Modified ABS generation particle preparation method

Abstract

The present invention relates to a modified ABS generation particle preparation method, which comprises: (1) crushing, cleaning and drying recovered waste computer shells so as to be spare, and controlling the moisture content of less than 0.01%, (2) crushing, cleaning and drying recovered waste PC mineral water buckets so as to be spare, and controlling the moisture content of less than 0.01%, and (3) adding the recovered ABS material, the recovered PC material, PMMA, ABS high glue powder and a MBS powder material to a high-speed kneader according to a ratio of 70:10:7:8:5, kneading for 20 min, discharging the material, pouring into a granulator material hopper, and carrying out extrusion granulation to obtain the modified ABS generation particles, wherein the process temperatures of the granulator extruder from the material feeding segment to the die head sequentially are 200 DEG C, 220 DEG C, 230 DEG C, 210 DEG C, 210 DEG C, 210 DEG C and 210 DEG C. The modified ABS generation particles produced by using the method have characteristics of strong aging resistance, high tensile strength and good bending strength.

Description

technical field [0001] The invention belongs to the field of ABS granules, in particular to a preparation method of modified ABS regenerated granules. Background technique [0002] At present, ABS recycled materials generally have problems such as aging, decrease in tensile strength, bending strength and notched impact strength, and low surface gloss. ABS / PC / PMMA is a mature technology in the industry. On the one hand, it improves the heat resistance and tensile strength of ABS. On the other hand, it reduces the viscosity of PC melt, improves processing performance, and reduces the sensitivity of product internal stress and impact strength to product thickness. sex. Improve heat resistance, impact resistance and rigidity of thin-walled products. Its tensile strength (Mpa) is 41.2, notched impact strength (J / M) is 457.8, and bending strength (Mpa) is 78.0, but it can only be used in refrigerators, telephone casings, etc. Contents of the invention [0003] The purpose of ...
