High-temperature resistant antistatic artificial synthetic stone and manufacturing process thereof

Abstract

The invention discloses a composite composition of antistatic artificial synthetic stone. The materials of the glue solution include polybismaleimide, bisphenol A novolac epoxy resin, bisphenol A epoxy resin, nanoscale silicon dioxide, high-strength hollow glass beads and conductive carbon ink; the solvent is dimethyl formamide and/or acetone/butanone; the reinforcing material is antistatic graphite glass fiber cloth and/or graphite glass fiber felt, wherein any one or two are used. The antistatic artificial synthetic stone disclosed by the invention solves the problems in high-temperature resistance of antistatic synthetic stone, high density of antistatic synthetic stone, uniform static conduction action of antistatic synthetic stone, thermal deformation of antistatic synthetic stone and influence on the health of users and operators caused by a little toxic smoke generated in the using process of the antistatic synthetic stone since the high-temperature resistance does not meet the requirements; moreover, the product density is reduced, and the problem of serious abrasion of the post-processing tool of the user is solved.
