▎ 摘  要

NOVELTY - Antistatic composition comprises a group (A) antistatic component comprising 80-100 parts mass bisphenol A type epoxy resin, 60-80 parts mass acrylic epoxy resin, 10-20 parts mass conductive inorganic substances, 5-10 parts mass curing agent, 1-5 parts mass reinforcing fibers and 1-4 parts mass processing aid, and a group (B) organic solvent. USE - The antistatic composition is useful for antistatic treatment of polymer composite materials (claimed). ADVANTAGE - The composition effectively improves the adhesion effect of the antistatic composition on the surface of the composite material product, reduces the problems of pure epoxy resin being easily oxidized outdoors, weathered and brittle, ensures to increase the shelf-life, and effectively reduces the cracking of the antistatic composition, and does not affect the mechanical properties of composite material products, and is applied through simple coating, and convenient for application. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the composition, involving adding bisphenol A epoxy resin, acrylic epoxy resin, and processing aids to an equipment, heating at 40-60℃, stirring, adding conductive inorganic substance, reinforcing fiber and curing agent to prepare the component of group (A), and mixing the group (A) component with the component (B) to obtain the composition.
