NOVELTY - Composite resin preparation involves weighing raw materials such as graphene oxide grafted acrylic acid, graphene oxide grafted modified methacrylic acid, methacrylic acid ethylene oxidic ester, n-butyl methacrylate, ethyl acrylate, octavinylsilsesquioxane, 600-1500 meshes benzoyl peroxide, 500-5000 meshes white corundum powder, 0.5 micro-chopped glass fiber, polymerization inhibitor, initiator and defoaming agent in mass ratio of 2-10:2-10:2-10:3-15:5-20:0.2-2:0.1-1:0.1-1:20-60:20-50:0.2-2:0.1-1:0.1-1:0.05-0.5 respectively. USE - Method for preparing composite resin (claimed). ADVANTAGE - The composite resin has good biological compatibility, better adhesive force, durability, abrasion resistance and aging resistance property. The composite resin is easy to prepare on large-scale. DETAILED DESCRIPTION - Composite resin preparation involves weighing raw materials such as graphene oxide grafted acrylic acid, graphene oxide grafted modified methacrylic acid, methacrylic acid ethylene oxidic ester, n-butyl methacrylate, ethyl acrylate, octavinylsilsesquioxane, 600-1500 meshes benzoyl peroxide, 500-5000 meshes white corundum powder, 0.5 micro-chopped glass fiber, polymerization inhibitor, initiator and defoaming agent in mass ratio of 2-10:2-10:2-10:3-15:5-20:0.2-2:0.1-1:0.1-1:20-60:20-50:0.2-2:0.1-1:0.1-1:0.05-0.5 respectively. Graphene oxide grafted acrylic acid and graft methacrylic acid are stirred in a high speed stirrer at 100-800 revolutions per minute, and then the quartz powder, white corundum chopped micro-glass fiber, polymerization inhibitor, initiator and de-foaming agents are added in stirrer at 200-2000 revolutions per minute for 5-30 minutes, stirring the material and vacuum packaging to obtain the paste.
