Description
C. DISCUSSION OF PRIOR ART AND BACKGROUND OF THE INVENTION
[0001] The application of protective roofing sheets, particularly
rubber roofing sheets, to the upper surface of a roof, involves the
use and application of an adhesive product applied to the upper
surface of the roof infrastructure. After a minimum limited waiting
period of approximately ten minutes, the bottom surfaces of the
roofing sheets are adhered flush against the upper surface portion
of the roof infrastructure on which the adhesive material is
applied. This minimum waiting period causes problems of the
inefficiency in the overall installation process. This adhering
process is adapted to create a firm bond between the upper surface
of the roof structure and the roof covering sheets, and with the
adhesive undersurface it creates a more substantial moisture
barrier to protect the integrity of the roof.
[0002] In the existing art, the adhesive glues or other substances
presently used to create this adhesion between the covering sheets
and roof structure generally have a significantly high viscosity.
Because of this high viscosity, the process of applying the
adhesive substance to the roof infrastructure requires a heavy
duty, high pressure spray mechanism that involves expensive
equipment. Moreover, because of the significant viscosity of the
adhesive substance used in this context, the sprayer must be
cleaned internally after each use, with solvents usually involving
high pressure injections. This itself has proven to be a time
consuming procedure.
[0003] Yet another consideration that is of significance in the use
of existing adhesive substance or glues is that when applied to the
upper surface of the base roof structure the adhesive substance
usually causes isolated globs or other imperfections in the
relative smoothness of the adhesive layering. These globs or
imperfections potentially eventually lead to blistering or
bubble-like rises which ultimately lessen the adhesive strength the
bond between the rubber roof sheets and the base roof
structure.
[0004] Another problem in the use of existing adhesive material for
fixing rubber roof sheets to a building structure is the toxicity
and environmental aspect. Almost all existing adhesive substances
on the market and in use today are comprised of chemicals that are
dangerous to the environment and potentially toxic to humans.
Because of this latter suspect and the other problems above
discussed there is a pressing need for improved adhesive substances
in this area.
D. OBJECTS OF INVENTION
[0005] The following are objects of the subject invention:
[0006] It is object of the subject invention to provide means to
adhere rubber roof sheets to a roof infrastructure.
[0007] It is also an object of the invention to provide improved
process methods to adhere rubber roof sheets to a roof
infrastructure.
[0008] An additional object of the subject invention is to provide
an improved method of affixing roof sheets to the upper surface of
a roof structure.
[0009] A further object of the subject invention is to provide am
improved process of applying an adhesive material to a roof
structure.
[0010] Yet another object of the subject invention is to provide an
improved roof sheet adhering process that is relatively economical
and safe to use from an environmental perspective.
[0011] A further object of the subject invention is to provide
efficient process and means to adhere roofing sheets to a roof base
structure.
[0012] Other and further objects of the subject invention can be
seen in the following description and claims read in view of the
drawings herein.
E. DESCRIPTION OF GENERAL EMBODIMENT AND SUMMARY OF INVENTION
[0013] The subject invention is a process for applying adhesive
product for adhering roof covering sheets to the upper surface of a
building, such process comprising applies in the following products
in various combination ratios:
[0014] (a) synthetic rubber and resin;
[0015] (b) toluene;
[0016] (c) cyclohexane;
[0017] (d) dearomatised petrol;
[0018] With such product being applied by utilizing a spraying
device to apply such product in an even layered film and then
adhering to the bottom surfaces of a roofing sheet over such
applied film. This positioning of the rubber roof sheets is
preferably consummated immediately after the application of the
adhesive product. Additionally certain other compounds may be added
to the above product to minimize the viscosity of the product and
render the product more compatible with the environment.
[0019] In using this general formulation to apply rubber roof
sheets or other types of roof sheets to the upper surface of a
roof, the product and process above described generates a less
viscous adhering substance that can for a given volume of advance
can cover, in some situations approximately ten times the surface
area that existing adhering products are capable of covering. This
aspect therefore means that a given volumetric unit of the subject
product can replace a larger quantity of the existing adhering
products to accomplish the same end result if adhering roofing
sheets. Additionally, the subject product as applied with the given
process, as generally described has a substantially greater
adhering capability and strength, with longer lasting adhering
effects.
[0020] Further, in using the subject product there is no necessity
to use a high pressure sprayer to apply the adhesive material by
reason of a lower viscosity and no need use expensive time
consuming procedures to clean the sprayer after each use. Indeed,
most low pressure sprayers will be adequate to accomplish the
spraying process in applying the subject adherent. Further the
adhering substance herein can also be sued to spray and coat the
insulation material used in the roofing infrastructure in order to
protect the integrity thereof. The environmentally compatible
aspects are such that the composition is easy to disintegrate into
a relatively harmless way into the environment.
[0021] An additional attribute of this product is that the
substance herein dries more quickly without bubbling and as a
result the roofing sheets can be applied more quickly so as to
render the overall adhesive and installation process more
efficient, with the end product having a greater adhesive
quality.
G. DESCRIPTION OF PREFERRED EMBODIMENT
[0022] In describing the preferred embodiment of the subject
invention it is to be stressed that the following description is
only of one specified embodiment of the invention. In so describing
a specified embodiment no limitation on the scope of the subject
invention will be construed as a result. Further, in describing the
subject invention and the components of the adherent substance it
is to be understood that the individual components, and specified
application process as specifically delineated, may include other
compounds, elements or process methods that fall within the same
general chemical classification for such specific product. If such
substitute substances or process means are not specifically
described it shall not limit the scope of the invention and the

[0024] It is to be noted that this formulation may vary from the
percentages described above. Moreover, this formulation may be
enhanced by the addition of various Hydrogen based compounds such
as hydrogen sulfide and other certain hydrogen compounds.
Additionally, certain nitrogen based compounds are helpful in this
formulation. Either or both the hydrogen or nitrogen based
compounds contribute to a certain degree to the lower viscosity of
the product and its adherent quality is helping to the ultimate
adhesive quality of the product, as well lowering the environmental
and health problems that are attendant with other existing adhesive
products used in this area.
[0025] In the preferred embodiment, the subject invention
compromises the process of applying the following product, or any
variant thereof including other compounds hydrogen or nitrogen
based compounds, or other additive.

[0030] Such application herein consummated by a sprayer applying a
film of such product over a roof surface and then placing the
bottom surface of one or more rubber roof sheets over the upper
surface of such film of adhesive material.
[0031] In summary, the subject invention is a process of applying
an adhesive for adhering roofing sheets to a roof surface comprised
of spraying an adhesive product comprising:
[0032] (a) synthetic rubber and resin;
[0033] (b) toluene;
[0034] (c) cyclohexane;
