Problems solved by technology

[0002] At present, the epoxy resin sheets on the market are all of a single color (that is, pure color). In order to change its color, you can consider adding quartz stone particles, but the quartz stone particles added during processing are prone to sedimentation, resulting in poor dispersion of product particles. uniform
In addition, the surface scratch resistance and temperature resistance of the obtained epoxy resin sheet are not ideal

Abstract

The invention relates to an epoxy resin composite board which comprises the following raw materials in parts by weight: 20-30 parts of epoxy resin, 3-8 parts of an amine curing agent, 55-70 parts of silica powder, 5-9 parts of graphene, 0.1-0.3 part of color paste, 0.1-0.3 part of a flame retardant aid, 0.05-0.2 part of a silane coupling agent and 0.5-2 part of natural minerals. The particle sizeof the silica powder is 300-500 meshes, and the particle size of the natural mineral substance is 50-250 meshes. The invention also relates to a preparation method of the epoxy resin composite board.According to the invention, graphene is added into an epoxy resin system to participate in reaction, and then natural minerals with different particle sizes are added to fill gaps of silica powder, sothat the plate is tighter, and the surface scratch resistance, wear resistance and temperature resistance of the plate are obviously improved. By adding the graphene and the silane coupling agent, the product is not easy to warp and deform.

Description

technical field [0001] The invention relates to the field of epoxy resin, in particular to a method for preparing an epoxy resin profile. Background technique [0002] At present, the epoxy resin sheets on the market are all of a single color (that is, pure color). In order to change its color, you can consider adding quartz stone particles, but the quartz stone particles added during processing are prone to sedimentation, resulting in poor dispersion of product particles. uniform. In addition, the surface scratch resistance and temperature resistance of the obtained epoxy resin sheet are not satisfactory. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and aims to provide an epoxy resin composite board with good surface scratch resistance and temperature resistance, and obvious improvement in color and luster and a preparation method thereof. [0004] Concrete technical scheme of the present invention is as follows: [0005...
