Modified abs special material for automobile and its production method

Abstract

The invention provides a modified ABS automobile special material comprising the following components in the formula in parts by weight: 100 parts of resin matrix ABS, 5-15 parts of active filler hollow microsphere, 4-8 parts of high rubber powder ABS, 0.5-0.8 part of age resister and 2-4 parts of master batch. In the above formula composition, the matrix resin ABS is granular substance; the active filler hollow microsphere is processed by silane coupling agent KH 550; the age resister mainly comprises master antioxidant, slave antioxidant and uvioresistant agent which are all powdery substance; the color of the master batch is determined according to product requirements, and the master batch is granular substance. The invention utilizes the principle that solubility parameters are similar; other polymers and various auxiliary agents, such as age resister, flexibilizer, fillers and the like are added into the ABS material and carry out molten mechanical mixing at certain temperature so as to obtain a new material applied on lorry parts.

Description

technical field [0001] The invention relates to the technical field of polymer modification, and relates to a formulation design technology and a production method of modified ABS automotive special materials. Background technique [0002] Due to the superior characteristics of plastics, a large number of plastics are used in automobile design, which can not only realize the lightweight design of automobile structures, but also comprehensively reflect the requirements for automobile design performance, namely lightweight, safety, anti-corrosion, shape and comfort. In addition, it is also beneficial to reduce costs and save material resources. [0003] ABS (acrylonitrile-butadiene-styrene copolymer) has many varieties, good surface treatment effect and low price. Therefore, it has always been popular in body materials and plays an important role in the production of auto parts. Although PP (polypropylene) has come from behind in the production of auto parts, the aristocrati...

AI Technical Summary

Problems solved by technology

[0005] 1. Generally, ABS is easy to degrade under the action of sunlight and hot oxygen due to its chemical structure containing double bonds, resulting in pulverization, discoloration and loss of some mechanical properties

[0006] 2. The strong light reflection in the cab of the car will cause discomfort and fatigue to the driver, and affect the driver's vision at night, so it is necessary to improve the surface roughness of the product
