PPE/PS alloy, preparation method and application thereof

Abstract

The invention discloses a PPE / PS alloy, which is prepared by compounding PPE and PS, so that a carbon nanotube has good dispersibility in an alloy resin matrix, the surface resistance of an injection molded part is greater than E5, the injection molded part is not easy to decarburize and high in thermal deformation temperature, and when glass fibers are added, the surface of the injection molded part has no floating fibers, and the PPE / PS alloy also has the advantage that the surface of the injection molded part has no floating fiber, and is suitable for preparing an ICTRAY disc.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PPE / PS alloy and its preparation method and application. Background technique [0002] Electronic packaging materials are developing rapidly with the development of the electronics industry. Electronic packaging materials include ICTRAY discs, carrier tapes, wafer boxes, etc. Taking ICTRAY discs as a class, the materials commonly used are conductive carbon black modified PPE (poly 2,6-dimethyl-1,4-phenylene ether) materials, carbon fiber reinforced PPE materials, glass fiber conductive carbon black modified Permanent PPE material, carbon fiber reinforced PES material, etc. [0003] In the prior art, the ICTRAY plate injection-molded with conductive carbon black modified PPE material has high surface gloss, strong toughness, and uniform distribution of resistance value. But there are disadvantages. When cleaning the dust on the surface with a hard brush, it is easy ...
