▎ 摘 要
NOVELTY - Silicone epoxy resin composition comprises: 2-6% epoxy-modified silicone oil, 15-30% bisphenol-A type epoxy resin, 3-6% epoxy resin curing agent, 60-79% transparent glass particles, 0.2-2% hydrophobic fumed silica, 0.01-0.05% graphene powder, where the epoxy resin curing agent comprises 10% ethoxy composition of propylamine, 40% diethylenetriamine and 50% acrylic acid as raw materials. USE - The silicone epoxy resin composition is useful as a concrete crack repairing material (claimed). ADVANTAGE - The silicone epoxy resin composition has fast curing speed, high strength, low shrinkage rate, high and low temperature resistance, and can replace the existing transparent concrete material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a silicone epoxy resin composition, comprises adding epoxy modified silicone oil and bisphenol-A type epoxy resin in a high speed disperser, stirring at 150-800 rpm for 15-30 min to obtain a mixture, adding hydrophobic white carbon black, graphene powder in the mixture, maintaining the temperature of 70-90 degrees C, stirring at 800-1000 rpm for 30-50 min, to obtain a solution-A, adding pre-mixed epoxy resin curing agent to solution, stirring at 800-1000 rpm for 5-10 min, then adding transparent glass particles at 300-400 rpm and stirring uniformly to obtain a mixture, pouring the mixture into a mold, and curing at room temperature for 8-24 hours to obtain a cured silicone epoxy resin composite material.
