Problems solved by technology

However, due to the flow orientation during molding caused by the anisotropy of the glass fiber itself, the longitudinal and transverse shrinkage of the glass fiber reinforced product is inconsistent, the product is prone to warping, and the surface of the product is relatively rough.

Abstract

The invention discloses a high-property resin / mica composite material, which comprises the following parts: resin, mica powder, short glass fiber, coupling agent, anti-oxidant and lubricant, wherein the resin is nylon or polyterephthalic acid butanediol ester. The manufacturing method comprises the following steps: adding mica powder into coupling agent to do activating disposal; combining the screw component of double-screw squeezer; allocating screw block through three-segment kneading pattern; blending each component or transmitting each component into double-screw squeezer; squeezing; graining.

Description

Technical field: [0001] The invention relates to a polymer material. Background technique: [0002] Nylon is a polymer material with a long history and a wide range of uses. It has good physical and mechanical properties, including excellent mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, and it is easy to process . In the past ten years, the average annual growth rate of nylon resin used as engineering plastics is about 8%, and it has been widely used in industries such as automobiles, electronic appliances, packaging, machinery, construction, etc. There is a lot of room for development. Pure nylon resin has the disadvantages of low heat distortion temperature and poor dimensional stability. It is easy to absorb water, and its mechanical properties are greatly reduced after absorbing water. [0003] At present, the reinforcement and modification of nylon is mainly through fiber reinforcement to improve its per...
