Description
BACKGROUND OF THE INVENTION
[0001] The present invention is directed to an aerosol paint
composition comprising a fungicide and to a sprayable aerosol
composition comprising the aerosol paint composition.
[0002] Although paints having mildew preventing agents are known,
it is difficult to formulate a sprayable aerosol composition having
a fungicide. In particular, it is difficult to incorporate a
fungicide into a solvent-based aerosol composition without the
fungicide becoming inactive. In addition, it is difficult to
incorporate a resin into a sprayable aerosol composition that
adheres to a wide variety of surfaces, especially to surfaces that
have been poorly cleaned.
[0003] It is an object of the present invention to develop a
sprayable aerosol composition containing a fungicide that can be
atomized properly in a continuous spray system, yet is thick enough
to cover a substrate completely in one coat, without sagging,
running, or dripping.
SUMMARY OF THE INVENTION
[0004] The aerosol paint composition according to the present
invention includes a resin; one or more solvents; a rheology agent;
an anti-settling agent; a dispersing agent; a pigment; a drying
agent; an anti-skinning agent; a fragrance; and a fungicide.
According to the present invention, the fungicide remains active in
a sprayable aerosol composition, the composition adheres well to
poorly-cleaned surfaces. The sprayable aerosol composition may be
used to provide both interior coatings and exterior coatings.
DETAILED DESCRIPTION OF THE INVENTION
[0005] According to the present invention, an aerosol paint
composition comprises a resin; one or more solvents; a rheology
agent; an anti-settling agent; a dispersing agent; a pigment; a
drying agent; an anti-skinning agent; a fragrance; and a fungicide.
The aerosol paint composition may also contain a filler or
extender. The aerosol paint composition may also contain an
anti-flocculation agent.
[0006] The resin in the aerosol paint composition of the present
invention acts as a binder which holds the various ingredients
together in a homogeneous mix and adheres to the substrate to be
coated or painted. In embodiments, the resin may be one or more of
an aromatic resin, alkyd resin, acrylic resin, polyester resin,
polyurethane resin, or epoxy resin. In preferred embodiments, the
resin may be an alkyd resin, including modified alkyds such as
vinyl toluene modified alkyd resins, acrylic modified alkyd resins,
styrene modified alkyd resins, acrylic/vinyl toluene modified alkyd
resins, and styrene/vinyl toluene modified alkyd resins. The resin
may be present in the aerosol paint composition in an amount of
about 10-70% by weight, preferably about 15-60% by weight, based
upon the total weight of the aerosol paint composition.
[0007] The aerosol paint composition may contain one or more
solvents. In embodiments, the one or more solvents include, but are
not limited to, an aromatic solvent, oxygenated solvent, aliphatic
solvent, or mixtures thereof. In preferred embodiments, the solvent
may be toluene, 150 Solvent, acetone, or mixtures thereof. 150
Solvent is a mixture of petroleum-based solvents generally
comprising aromatic petroleum distillates (96+%) and having a flash
point of about 150.degree. F. 150 Solvent is commercially available
as Hi Sol 15 or Aromatic 150. The one or more solvents may be
present in the aerosol paint composition in an amount of about
10-50% by weight, preferably about 15-40% by weight, based upon the
total weight of the aerosol paint composition.
[0008] The aerosol paint composition also comprises a rheology
agent. Suitable rheology agents may comprise organoclays, fumed
silica, dehydrated castor oil organic derivatives, English China
Clay; polyamides, polyimide modified alkyds, alkylbenzene
sulphonate derivatives, calcium and zinc stearates, calcium soyate,
and the like. In embodiments, the organoclay may be a clay such as
bentonite, smectite, kaolin, or montmorillonite to which organic
structures have been chemically bonded. Examples include, but are
not limited to, CLAYTONE.RTM. and TIXOGEL.RTM. organoclay additives
available from Southern Clay Products. The rheology agent allows
the paint to form a film without sagging or dripping. The rheology
agent may be present in the aerosol paint composition in an amount
of about 0.1-5% by weight, preferably about 0.1-3% by weight, based
upon the total weight of the aerosol paint composition.
[0009] The aerosol paint composition also comprises a dispersing
agent to aid in the uniform dispersing of various pigments and/or
powders into uniform particle size. The dispersing agent reduces
the time required to grind pigments and/or powders. The dispersing
agent also aids in maintaining a homogenous mix over time. The
dispersing agent is preferably polymeric and may include, but is
not limited to, dispersants sold under the trade names
Disperbyk.RTM. (an alkylammonium salt of a polyfunctional polymer
available from BYK-Chemie, USA), Anti-Terra-U (a solution of
unsaturated polyamine amides and acid polymers available from
BYK-Chemie, USA), Solsperse.RTM. (Avecia) and EFKA (EFKA
Chemicals). The dispersing agent may be present in the aerosol
paint composition in an amount of about 0.2-2% by weight,
preferably about 0.2-1% by weight, based upon the total weight of
the aerosol paint composition.
[0010] The aerosol composition may comprise one or more
anti-flocculation agents which work in conjunction with the
dispersing agent to enhance its effect. The anti-flocculation agent
also reduces the chance that different colored pigments will
separate from other and group together to form streaks or patches.
In embodiments, such flocculation agents include, but are not
limited to, Imperial Antifloat Compound (IAF) Compound X-2280
(barium sulfate). The anti-flocculation agent may be present in the
composition in an amount of about 0.1-2% by weight, preferably
about 0.2-1% by weight, based upon the total weight of the aerosol
paint composition.
[0011] The aerosol composition comprises one or more pigments to
impart various colors and shades. Suitable pigments are well known
in the art and are typical organic pigments, inorganic pigments, or
mixtures thereof. Example of such pigments include, but are not
limited to, titanium dioxide, carbon black, graphite, ceramic
black, antimony sulfide, black iron oxide, aluminum pastes, yellow
iron oxide, red iron oxide, iron blue, phthalo blue and green,
nickel titanate, dianisidine orange, dinitroaniline orange,
imidazole orange, quinacridone red, violet and magenta, toluidine
red, molybdate orange, and the like. The pigment may be present in
the aerosol composition in an amount of about 5-50% by weight,
preferably about 10-40% by weight, based upon the total weight of
the aerosol composition.
[0012] The aerosol composition may comprise one or more extenders
or fillers to reduce the cost and increase the opacity of the paint
film. Suitable fillers may include, but are not limited to,
amorphous, diatomaceous, fumed, quartz and crystalline silica,
clays, aluminum silicates, magnesium aluminum silicates, talc,
mica, delaminated clays, calcium carbonates and silicates, gypsum,
barium sulfate, zinc, calcium zinc molybdates, zinc oxide,
phosphosilicates and borosilicates of calcium, barium and
strontium, barium metaborate monohydrate, and the like. In
embodiments, the filler may be calcium carbonate such as
VICRON.RTM. 15-15. The filler may be present in the aerosol
composition in an amount of about 0-50% by weight, preferably about
5-40% by weight, based upon the total weight of the aerosol
composition.
[0013] The aerosol paint composition comprises one or more drying
agents to increase the speed with which the resin forms a hard film
(i.e., cures). Drying agents include, but are not limited to,
metallic and rare earth driers such as cobalt, calcium, potassium,
barium, zinc, manganese, tin, aluminum, zirconium and vanadium
napthenates, octoates, hexanates, and isodecanoates. In
embodiments, the drying agent may comprise a cobalt drier. Cobalt
driers include, but are not limited to, an organic cobalt salt such
as cobalt naphthenate or cobalt octoacte. The drying agent may be
present in the aerosol paint composition in an amount of about
0.05-0.5% by weight, preferably about 0.05-0.4% by weight, based
upon the total weight of the aerosol paint composition.
[0014] The aerosol paint composition may comprise one or more
anti-skinning agents to inhibit the skinning or formation of a
solid film at the surface of the liquid paint while it is kept in
storage (e.g., in drums or cans). In embodiments, the anti-skinning
agent may include, but is not limited to, methyl ethyl ketoxime,
o-cresol, or hydroquinone. An example of a commercially available
anti-skinning agent is Exkin or Trokyd AntiSkin. The anti-skinning
agent may be present in the aerosol paint composition in an amount
of about 0.1-0.5% by weight, preferably about 0.2-0.4% by weight,
based upon the total weight of the aerosol paint composition.
[0015] The aerosol paint composition may comprise one or more
fragrances. The fragrance may be used to reduce the offensive smell
often associated with spray paint. Any desirable known scenting or
fragrance types may be employed provided that the fragrance is
compatible with the other ingredients in the mixtures. Examples of
scents or fragrances for use in the present invention include, but
are not limited to, citrus fragrances such as commercially
available Citrus Fragrance Z-125-04; floral fragrances; fruit
fragrances; spice fragrances; and vanilla fragrances. The fragrance
may be present in the aerosol paint composition in an amount of
about 0.1-3% by weight, preferably about 0.1-2% by weight, based
upon the total weight of the aerosol paint composition.
[0016] The aerosol paint composition comprises one or more
fungicides to inhibit the growth of mold or mildew on the surface
of the paint. In embodiments, the fungicide may comprise
3-Iodo-2-propynl butyl carbamate. The fungicide may be
FUNGITROL.RTM., commercially available from Degussa Corporation or
International Specialty Products. However, thiabendazole and
diiodomethyl p-tolyl sulfone will not work in the aerosol paint
composition or sprayable aerosol formulation of the present
invention. Thus, AMICAL 48, commercially available from Dow
Chemical Co.; THIABENDAZOLE DISPERSION W, commercially available
from Lanxess Corporation; or FUNGITEX TBZ, commercially available
from CIBA Specialty Chemicals are incompatible with the aerosol
composition. The fungicide may be present in the aerosol paint
composition in an amount of about 0.1-3% by weight, preferably
about 0.1-1% by weight, based upon the total weight of the aerosol
paint composition.
[0017] The aerosol paint composition also comprises one or more
anti-settling waxes to prevent hard settling of the paint while it
is not in use. The pigments that are used to give color to the
paint are fairly heavy and tend to settle to the bottom of any
liquid medium when they are stored for extended periods. The
anti-settling wax prevents these pigments from forming a hard,
compacted, solid mass. This allows the aerosol can to be shaken and
for the homogenous state of the paint mixture to be restored. In
embodiments, the wax may be SUSPENO.RTM., commercially available
from Poly-Resyn, Inc. The anti-settling wax may be present in the
aerosol paint composition in an amount of about 0.5-5% by weight,
preferably about 1-3% by weight, based upon the total weight of the
aerosol paint composition.
[0018] The aerosol paint composition of the present invention is a
concentrate and may be combined with additional thinning solvents
and propellants to obtain a sprayable aerosol formulation. In
embodiments, the propellant may comprise propane, butane, or
combinations thereof. An example of the thinning solvent includes
acetone and an example of the propellant includes A-80 having a
pressure of about 80 psi.
[0019] According to the present invention, different methods may be
used in the manufacture of the aerosol paint composition. In
embodiments, a first method involves grinding the one or more
pigments into the resin with a high-speed dispersion mixer (such as
a cowles). Shading pastes may be subsequently added for color
correction. A second method involves grinding both white and
colored pigments using a high-speed mill, for example, a sandmill.
Shading pastes may be subsequently added for color correction. The
mixing speeds and temperatures may vary with the aerosol paint
composition and the equipment used. In embodiments, temperature of
about 100.degree. F. or higher may be reached due to milling and
grinding. In embodiments, mixing speeds may be up to about 10,000
rpm.
[0020] The sprayable aerosol formulation may be used with any
appropriate valve and actuator. In embodiments, the valve may be
model SV-77/U13 (Dip tube, AD Plain; Mount cup, EPT/LAMB con;
Gasket, 0.050 Butyl SV-77/92; Spring, 0.023; Body, BV assy
1.times.0.045 RE 1/8 inch SS Ball; Stem, 2.times.0.020 .349Nat).
The actuator may be a 35 mm actuator and overcap assembly
(0.020.times.0.030).
