Double-layer co-extrusion high-toughness static PS (polystyrene) black sheet

Abstract

The invention discloses a double-layer co-extrusion high-toughness static PS (polystyrene) black sheet, comprising a layer A and a layer B, wherein the layer A is attached above the layer B; the layer A is prepared from the following materials in parts by mass: 80-100 parts of special rubber and 2-5 parts of an antistatic agent; the layer B is prepared from the following materials in parts by mass: 50-60 parts of PS resin, 2-5 parts of an antistatic agent, 2-6 parts of SBS (styrene / butadiene / styrene block copolymer) resin, 10-15 parts of diffusion oil, 2-6 parts of an antioxidant and 2-3 parts of black color masterbatch. According to the double-layer co-extrusion high-toughness static PS black sheet, the soft protection for an electronic material is realized by the layer A, and the hard protection for the electronic material is realized by the layer B; furthermore, the double-layer co-extrusion high-toughness static PS black sheet is also capable of effectively preventing static electricity; the double-layer co-extrusion high-toughness static PS black sheet is simpler in structure and more convenient to manufacture, thus being suitable for promotion and use.

Description

Technical field [0001] The invention relates to a double-layer co-extruded high-toughness electrostatic PS black sheet. Background technique [0002] The outside of the electronic material is usually wrapped with a rubber sheet, but the rubber sheet in the prior art has a relatively large hardness and cannot form a flexible protection for the electronic material. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a double-layer co-extruded high-toughness electrostatic PS black sheet. The present invention realizes the soft protection of electronic materials through the A layer and the hard protection of the electronic materials through the B layer. Effectively prevent static electricity. [0004] To solve the above problems, the present invention adopts the following technical solutions: [0005] A two-layer co-extruded high-toughness electrostatic PS black sheet material, comprising a layer A and a layer B, the layer A is att...
