Problems solved by technology

[0009] The mechanical properties of glass fiber reinforced AS largely depend on the bonding strength of AS and glass fiber. Due to the poor interface bonding between resin and glass fiber, the reinforcing effect of glass fiber cannot be fully exerted. The strength, toughness, and Poor performance such as heat resistance
[0010] In addition, because AS material is a poor conductor of electricity, it is easy to accumulate static charge during processing and use. When the static charge accumulates to a certain extent, static electricity will cause the material to absorb dust, cause material damage, and may also generate static spark discharge, causing The chemical product warehouse exploded and caught fire, causing major personal accidents

Abstract

The invention relates to a low-odor antistatic high-performance glass fiber reinforced AS composition, which contains, by weight, 30-80% of AS resin, 10-30% of glass fiber, 1-10% of a compatilizer, 1-5% of jellyfish granules, 0.1-1% of a coupling agent, 10-15% of an antistatic agent and 0.1-3% of an auxiliary agent. The total percentage of the above components is 100%. The antistatic agent is a permanent antistatic agent and contains molecular distilled glycerin monostearate component, which is specifically hardened palm glyceride. The jellyfish granules used in the invention are easily available, has advantages of simple preparation technology and low cost, can effectively remove odor and will not influence mechanical property of the composition. By adding the antistatic agent, surface resistivity of the AS composition can be reduced from 1016 Omega to 109 Omega, and the antistatic effect is good.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a low-odor, antistatic high-performance glass fiber reinforced AS composition and a preparation method thereof. Background technique [0002] Acrylonitrile-styrene (AS) resin is a thermoplastic made by copolymerizing two monomers of styrene (St) and acrylonitrile (AN). AS resin has excellent properties, excellent dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and mechanical processing, and is an important engineering plastic. [0003] Glass fiber reinforced AS has good application value in the field of household appliances due to its good processability, dimensional stability and tensile strength, such as axial flow, cross flow and centrifugal fan blades in air conditioners. The performance of glass fiber reinforced AS parts directly affects the quality of air conditioners and is closely related to our daily life. ...
