▎ 摘　　要

NOVELTY - A high-temperature resistant, creep-resistant graphene modified phenolic foam comprises 90-100 pts. wt. phenolic resin, 0.5-0.9 pt. wt. graphene, 2-3 pts. wt. phosphoric acid, 18-20 pts. wt. polyisocyanurate, 8-10 pts. wt. polysorbate, 12-14 pts. wt. dichlorotetrafluoroethane, 6-7 pts. wt. isophorone diamine, 5-8 pts. wt. dichloromethyltriethoxysilane, 2-4 pts. wt. diacetyl peroxide, calcium stearate, acetyl tributyl citrate, propyl gallate, basic magnesium carbonate, zirconium powder, asbestos fiber, aluminum hydroxide, talc powder, white carbon black, calcined kaolin and water. USE - High-temperature resistant, creep-resistant graphene modified phenolic foam (claimed). ADVANTAGE - The fragility of the foam is reduced, while the intrinsic properties of graphene enhance the endothermic capacity of the foam. The phenolic foam can prevent the occurrence of high temperature creep, and achieves excellent flame retardance property. DETAILED DESCRIPTION - A high-temperature resistant, creep-resistant graphene modified phenolic foam comprises 90-100 pts. wt. phenolic resin, 0.5-0.9 pt. wt. graphene, 2-3 pts. wt. phosphoric acid, 18-20 pts. wt. polyisocyanurate, 8-10 pts. wt. polysorbate, 12-14 pts. wt. dichlorotetrafluoroethane, 6-7 pts. wt. isophorone diamine, 5-8 pts. wt. dichloromethyltriethoxysilane, 2-4 pts. wt. diacetyl peroxide, 5-7 pts. wt. calcium stearate, 3-5 pts. wt. acetyl tributyl citrate, 7-9 pts. wt. propyl gallate, 10-12 pts. wt. basic magnesium carbonate, 24-30 pts. wt. zirconium powder, 7-9 pts. wt. asbestos fiber, 6-8 pts. wt. aluminum hydroxide, 5-7 pts. wt. talc, 4-6 pts. wt. white carbon black, 8-10 pts. wt. calcined kaolin and 20-25 pts. wt. water. An INDEPENDENT CLAIM is included for preparation of high-temperature resistant, creep-resistant graphene modified phenolic foam, which involves adding phenol resin, graphene and phosphoric acid, mixing into a blender, and stirring for 20-25 minutes to mix the mixture evenly, then heating at 175-180 degrees C, heat-preserving for 50-60 minutes to obtain a graphene-modified phenolic resin, (ii) adding basic magnesium carbonate, zirconium powder, asbestos fiber, aluminum hydroxide, talc powder, white carbon black and calcined kaolin together into a ball mill, finely grinding, controlling the particle size of the mixture to 1-2 mm, placing the finely grinded mixture in a stirring apparatus, and adding half of the water, fully mixing to obtain a mixed slurry, (iii) adding graphene-modified phenolic resin and the mixed slurry into an open mill, milling for 3-5 minutes at a temperature of 100-110 degrees C, then adding polyisocyanurate, polysorbate, dichlorotetrafluoroethane, isophorone diamine, dichloromethyltriethoxysilane, diacetyl peroxide, calcium stearate, acetyl tributyl citrate, propyl gallate and other raw materials and the remaining water, refining at 90-100 degrees C for 5-8 minutes to obtain a mixture, placing the mixture into a foam mold in the environment of 60-80 degrees C, carrying out foam reaction for 40-60 minutes to obtain the phenolic foam material.
