摘要：NOVELTY - An environmentally-friendly anti-ablative silicone rubber ceramic composite material comprises 50-150 parts mass silicone rubber, 20-80 parts mass white carbon black, 0.1-20 parts mass silicone oil, 5-80 parts mass porcelain powder, 5-30 parts mass melt additives, 5-20 parts mass coupling agent and 0.1-5 parts mass vulcanizing agent. The silicone rubber is methyl vinyl silicone rubber and/or methyl phenyl vinyl silicone rubber. The white carbon black is fumed silica and/or precipitated silica. The melt additive is lithium ceramic powder, borax and/or boric acid. USE - Anti-ablative environmentally-friendly silicone rubber ceramic composite material (claimed). ADVANTAGE - The environmentally-friendly silicone rubber ceramic composite material has excellent ablation resistance and mechanical properties. DETAILED DESCRIPTION - An environmentally-friendly anti-ablative silicone rubber ceramic composite material comprises 50-150 parts mass silicone rubber, 20-80 parts mass white carbon black, 0.1-20 parts mass silicone oil, 5-80 parts mass porcelain powder, 5-30 parts mass melt additives, 5-20 parts mass coupling agent and 0.1-5 parts mass vulcanizing agent. The silicone rubber is methyl vinyl silicone rubber and/or methyl phenyl vinyl silicone rubber. The white carbon black is fumed silica and/or precipitated silica. The silicone oil is hydroxy silicone oil, methyl hydrogen silicone oil and/or high-vinyl silicone oil. The porcelain powder includes aluminum oxide, zirconium oxide, magnesium oxide, zinc oxide and/or titanium oxide. The melt additive is lithium ceramic powder, borax and/or boric acid. An INDEPENDENT CLAIM is included for preparation of environmentally-friendly anti-ablative silicone rubber ceramic composite material, which involves mixing silicone rubber, white carbon black and coupling agent in an internal mixer at 80 degrees C or less, adding porcelain powder, melt additive and silicone oil, uniformly mixing, forming a ceramic silicone rubber, removing and cooling the ceramic silicone rubber to 25-30 degrees C, placing the obtained product in an open mill, adding curing agent and vulcanizing agent, mixing at 50 degrees C or less, molding using 25 ton flat plate curing device under 15 MPa at 160-180 degrees C for 4-20 minutes, and drying in air at 200 degrees C.
