Abstract

The invention discloses a perpetual anti-static weather-resistant PC / ASA material and a preparation method thereof. PC, SAN resin and ASA high glue powder are mixed according to a certain ratio, and the mixture is added with a static inhibitor, a compatilizer, an anti-ultraviolet light auxiliary agent and a certain amount of a photostabilizer to obtain the perpetual anti-static high-weather-resistance PC / ASA material which is high in electrostatic dissipation ability and high in weather resistance; as long as a small amount of perpetual static inhibitor is added in the material, requirements of mass PV3977 and PV1303 can be met; and the performance of the material can meet the requirements of a mass material testing schedule TL52652A. According to the preparation method of the perpetual anti-static high-weather-resistance PC / ASA material, screw combination is reasonable, the process is simple, and the prepared perpetual anti-static high-weather-resistance PC / ASA material is good in anti-static property and high in weather resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a PC / ASA material with permanent antistatic and high weather resistance and a preparation method thereof. Background technique [0002] Most polymer materials tend to accumulate static electricity during production and use, resulting in electrostatic dust collection, electrostatic discharge and other undesirable phenomena. In severe cases, sparks can be generated, causing fire or explosion, which brings troubles to industrial production and daily life. Therefore, The research on materials with antistatic function has attracted people's attention. [0003] At present, the antistatic function of antistatic resin materials is mostly realized by adding antistatic agents. Traditional antistatic agents are composed of small molecule surfactants, composed of hydrophilic groups and hydrophobic groups. The antistatic agent migrates from the inside of the resin to the surface of t...
