Production method of ABS mixing auxiliary bag

The invention relates to a production method of an ABS mixing auxiliary bag. The production method is characterized by including the following steps that diphosphite, ethylene bis stearamide and magnesium stearate are accurately metered through a weightlessness feeder according to the mass ratio and added into a vertical helix ribbon high-speed mixer, and the temperature, stirring rotating speed and mixing time are controlled in the mixing process; the mixed material is added into a screw extruder through the feeder, and the material amount in the screw extruder and the temperature in the screw extruder are controlled; nitrogen air cooling is carried out on the extruded product, and the extruded product is conveyed into a vacuum packager to be packaged after being cooled to obtain the auxiliary bag. The auxiliary bag, ABS powder and SAN are mixed and granulated, performance indexes such as whiteness, yellowness, impact strength, melt index, tensile strength and bending strength of the prepared ABS are tested,
