[0003] Description of Related Art
[0004] High performance silicone rubber is a kind of organic
polymer material with advantages of high elasticity, heat-and-cold
resistance, weather resistance, ozone and UV resistance, radiation
resistance, electrical insulation, physiological inertia and high
permeability. It can be widely used in various industries including
aerospace, electrical and electronic, machinery, chemical industry,
building materials, and health care as well as in daily life. The
silicon rubber industry has developed very rapidly in recent years.
Presently, high performance silicon rubber is heavily used in the
fields of building, sealing, electrical, electronic, and
automobiles. In the near future, automobile, electrical and
electronic likely will replace the construction and building to
become the main consumer market. Although mechanical properties,
stability, adhesiveness, thermal and electrical properties of
silicon rubber have always been the focus of the market, the
concern of surrounding environment and self-health status has been
increased drastically. As a result, there is an increased emphasis
on the environmental performance of the high performance silicon
rubber.

rubber protection shell and the manufacturing methods for meeting
the development demands of high performance eco-friendly silicon
rubber.

gel to get a mixture, then mix the mixture with 75% of
anion-carried capsule mesoporous silica microsphere, silicon
nitride micro powder and nano-biomass silica hydrated micro powder;
grind the mixer in the ultrafine grinder for 30 to 40 minutes;

adopt injection molding method to get the eco-friendly bottom shell
for preparation of the next step;
[0010] Cooling the eco-friendly bottom shell, then place into the
prepared mold and assembly the mold to the injection molding
machine for preparation of the next step;

super-dissolving silica gel micro powder in which the weight
percentage of nano platinum contained is 15% to manufacture the
computer protection shell through bottom shell and internal surface
injection molding, which has advantages of good mechanical property
and conductivity.
[0013] Meanwhile, adding anion-carried capsule mesoporous silica
microsphere in the manufacturing process can further improve the
protective function of the protection shells, as well as enhancing
the function of environmental protection; adding colored gel can
enable the color-control of the protection shells; adding silicon
nitride micro powder, fiberglass and nano-biomass silica hydrated
micro powder can help to improve the hardness, compressive capacity
and environmental safety of the protection shells.
