Thermal protective coatings for supersonic flight
When supersonic aircraft fly in the atmosphere, its surface temperature will be as high as 400 ~ 500℃. E-type epoxy resin modified by phenyl silicone resin has good performance, its tensile strength is not less than 7.1MPa, the elongation at break reaches 1.04%, and the adhesion reaches 498.4N/cm2. The specific heat capacity is 1.627×103J/(kg·K), the thermal conductivity is only 0.146W/(m·K), the thermal insulation parameters are 0.087kg2/(m4·s), the linear ablation rate of oxygen-acetylene ablation is 0.194 mm/s, and the mass ablation rate is 0.0729g/s. The thermal insulation test results show that, Its back wall temperature does not exceed 260℃ at an ambient temperature of 500℃.
Floor coating with good impact resistance and long term antifouling
At present, the main products of floor coatings are epoxy and polyurethane systems, but they still have some problems in impact resistance and long-term antifouling, for this, Guangzhou Chemical Co., Ltd. of Chinese Academy of Sciences developed silicone modified epoxy resin floor coatings with good impact resistance and long-term antifouling.
Nuclear radiation resistant coating
Radiation resistant coatings are mainly used for nuclear reactor, nuclear power plant, isotope test and other vulnerable to radioactive contamination of internal and external surfaces of the building, installation and equipment protection, required coating with high resistance to radiation and easy decontamination, corrosion resistance and other should have special chemical resistance, and can absorb radiation, radioactive sources in order to protect the surrounding environment.
