Abstract

The invention discloses a production method of an ABS composite powder additive. The production method comprises the process steps of vacuum powder feeding, powder weightlessness flow metering and powder conveying, mixing and extrusion, air cooling, pelletizing and screening, air conveying, storage and packaging. The dispersion uniformity of the obtained additive in an ABS product is relatively better, the defective rate of an ABS device is reduced, the ABS device can realize automatic vacuum feeding of the powder additive, , and various properties of the ABS product prepared by mixing the composite additive with ABS powder and SAN for granulation are greatly improved.

Description

technical field [0001] The invention relates to an auxiliary agent for ABS resin mixing, in particular to a production method of an ABS composite powder auxiliary agent. Background technique [0002] In ABS production, ABS resin and SAN resin need to be mixed. Before ABS resin and SAN resin are mixed, ethylene bis stearamide (hereinafter referred to as EBS), phosphite antioxidant (hereinafter referred to as SPEP), After auxiliary agents such as magnesium stearate (hereinafter referred to as MAGST) and ABS resin and SAN resin carry out simple physical mixing, add in ABS resin and SAN resin according to certain ratio, there is following problem in the production technology of prior art: [0003] (1) Magnesium stearate (MAGST) needs to be conveyed to the silo by air conveying and materials such as ABS and SAN after feeding. The magnesium stearate particles are fine, and the material loss is large during the air conveying process (partially enters the dust collector), resulting ...
