NOVELTY - Preparing a heat-resistant composite material involves adding graphene oxide into N,N-dimethyl dodecylamine under stirring for 1 hours at 100 degrees C, then adding diphenoxyphosphine and strontium titanate, under stirring for 0.5 hours, and ammonium hexachloroiridate under stirring for 10 Minutes, then natural cooled to obtain graphene composite metal. The polyester resin, graphene composite metal, naphthol phenolic resin, maleic anhydride, and titanium dioxide whisker are dried, then crushed and uniformly added to the extruder at 195 degrees C to obtain mixture particles. USE - Method for preparing a heat-resistant composite material (claimed). ADVANTAGE - The method enables to prepare heat-resistant composite material, which has excellent heat resistance, flame retardant property, good processing performance, where the outer layer material with graphene, N,N-dimethyl lauryl amine and strontium titanate together improves the corrosion resistance property of the material, and used for modular application. DETAILED DESCRIPTION - Preparing a heat-resistant composite material involves adding graphene oxide into N,N-dimethyl dodecylamine under stirring for 1 hours at 100 degrees C, then adding diphenoxyphosphine and strontium titanate, under stirring for 0.5 hours, and ammonium hexachloroiridate under stirring for 10 Minutes, then natural cooled to obtain graphene composite metal. The polyester resin, graphene composite metal, naphthol phenolic resin, maleic anhydride, and titanium dioxide whisker are dried, then crushed and uniformly added to the extruder at 195 degrees C to obtain mixture particles. The mixture particles are added into film making machine to obtain outer layer material. The outer layer material is mixed with N-4-hydroxyphenyl maleimide and cyanate under stirring for 5 minutes at 120 degrees C, then added with phosphorus-containing phenolic resin, under stirring for 50 minutes, then with glyceryl monostearate, polyurea formaldehyde, under stirring for 20 minutes, methyl cyclohexene tetracarboxylic dianhydride and dicarboxy phthalimide, under stirring for 10 minutes, 1,8-octanedithiol, dibutyl zinc dilaurate, under stirring 5 minutes into the mold, and subjected to natural cooling to obtain middle material. The polystyrene, polyphenylene sulfide and hollow alumina are dried and mixed with 3,5-dimethylpyrazole, silicone phenolic resin and polyvinyl alcohol into an extruder at 175 degrees C to obtain second mixed particles, which are added into film making machine to obtain the inner material. The outer layer material, middle layer material and inner layer material are sequentially added into mold, and subjected to hot-pressing to obtain desired product.
