Polycarbonate plastic sheet

Abstract

The invention discloses a polycarbonate plastic sheet. The polycarbonate plastic sheet comprises polycarbonate plastics and additives, wherein the additives comprise a shock resistant modifier, an ultraviolet absorber, a slip agent, an antifogging agent, a nucleating agent and a cross-linking agent, wherein the shock resistant modifier is ethylene-vinyl acetate copolymer, the ultraviolet absorber is benzophenone, the slip agent is organic siloxane emulsion, the antifogging agent is sorbitan monopalmitate, the nucleating agent is butadiene rubber, and the cross-linking agent is poly alkyl acrylate. The polycarbonate plastic sheet has high shock resistance, is not easy to scratch, can well absorb ultraviolet rays of sunlight, and has a long service life. And the lens has a smooth surface and fog is not easy to form on the surface of the lens.

Description

technical field

[0001] The invention relates to a decorative material, in particular to a polycarbonate plastic sheet. Background technique

[0002] Most of the spectacle lenses made of polycarbonate plastic sheets currently on the market have a short service life, and they are prone to scratches, roughness, fogging on the lens surface, and weakening of ultraviolet rays during use. Smaller, more damage to the eyes. Contents of the invention

[0003] The object of the present invention is to provide a polycarbonate plastic sheet with high impact resistance, smoothness, anti-fog and ultraviolet absorption.

[0004] The technical solution of the present invention is a polycarbonate plastic sheet, including polycarbonate plastic and additives, and the additives include impact modifiers, ultraviolet light absorbers, slip agents, antifogging agents, and nucleating agents and a crosslinking agent, the impact modifier is ethylene-vinyl acetate copolymer, the ultraviolet light ab...
