▎ 摘  要

NOVELTY - Epoxy resin cement comprises component A aandnd component B, and the usage ratio of component A and component B is 3-6:1, component A contains 40-60 pts. wt. epoxy resin, 13-23 pts. wt. thinner, 8-12 pts. wt. surfactant, 3-5 pts. wt. epoxycyclohexyl-cage polysilsesquioxane structure (1), 5-8 pts. wt. silane coupling agent, 10-14 pts. wt. fumed silica, 8-12 pts. wt. unsaturated polyester resin, 18-25 pts. wt. nano light calcium bromide, component B contains 60-80 pts. wt. hardener, 10-20 pts. wt. DMP-30 (RTM: 2,4,6-tris(dimethylaminomethyl)phenol) accelerator, 15-20 pts. wt. ultraviolet absorber, 2-5 pts. wt. aramid fiber powder, 2-5 pts. wt. flame retardant, 2-5 pts. wt. graphene oxide nanosheets. USE - Epoxy resin cement used for hydraulic and hydroelectric engineering, bridge engineering, high-speed rail traffic engineering, building engineering and the like. ADVANTAGE - Environment-friendly anti-abrasion and anti-deterioration epoxy resin cement has higher strength, toughness, impact resistance and abrasion resistance, the ultraviolet aging resistance, flame retardance, thermal linear expansion coefficient and the like of the epoxy resin cement are obviously improved, the problems of curling, shelling and cracking in the construction process are solved, the comprehensive performance is good. DETAILED DESCRIPTION - Epoxy resin cement comprises component A and component B, and the usage ratio of component A and component B is 3-6:1, component A contains 40-60 pts. wt. epoxy resin, 13-23 pts. wt. thinner, 8-12 pts. wt. surfactant, 3-5 pts. wt. epoxycyclohexyl-cage polysilsesquioxane of structure (1) R=alkyl group, 5-8 pts. wt. silane coupling agent, 10-14 pts. wt. fumed silica, 8-12 pts. wt. unsaturated polyester resin, 18-25 pts. wt. nano light calcium bromide, component B contains 60-80 pts. wt. hardener, 10-20 pts. wt. DMP-30 (RTM: 2,4,6-tris(dimethylaminomethyl)phenol) accelerator, 15-20 pts. wt. ultraviolet (UV) absorber, 2-5 pts. wt. aramid fiber powder, 2-5 pts. wt. flame retardant, 2-5 pts. wt. graphene oxide nanosheets. An INDEPENDENT CLAIM is included for preparation method of epoxy resin cement involves mixing epoxy resin, diluent and surfactant in component A, stirring evenly, adding it into a shearing disperser, and then adding epoxycyclohexyl-cage polysilsesquioxane, silane coupling agent, fumed silica and nano light calcium bromide, shearing and dispersing to a fineness of less than 50. Mixing curing agent and DMP-30 accelerator in component B, stirring evenly, adding it into a shearing disperser, adding UV absorber, aramid fiber powder, flame retardant and graphene oxide nanosheets, grind to fineness less than 50. Mixing the mixture prepared in step (1) and step (2) in proportion, and shearing and dispersing with a shearing disperser.
