NOVELTY - Thermosetting composite material with high gloss and superior electrical properties comprises 15-50 pts. wt. unsaturated polyester-o-benzene-graphene composite resin, 0.5-1.5 pts. wt. curing agent, 30-50 pts. wt. inorganic filler, 70-120 pts. wt. calcium carbonate, 0.1-1 pts. wt. wetting agent, 0.1-0.5 pts. wt. thickener, 1-3 pts. wt. release agent, 10-30 pts. wt. alkali-free high-strength fiber, and 0.5-1.8 pts. wt. auxiliary agent. USE - Thermosetting composite material with high gloss and superior electrical properties. ADVANTAGE - The thermosetting composite material with high gloss and superior electrical properties solves the problems of low gloss, low density, low bending strength, poor insulation effect and poor environmental protection performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a thermosetting composite material with high gloss and superior electrical properties, which involves: (A) stirring o-phthalic resin, unsaturated polyester, and graphene at high speed according to obtain a composite resin; (B) mixing the composite resin obtained with the required curing agent, wetting agent and thickener to obtain a mixture A; and (C) pouring the mixture A into the kneader, and sequentially adding the required calcium carbonate, silicone oxide release agent, alkali-free high-strength fiber and auxiliary agents and mixing to obtain final product.
