Automobile corrugated pipe plastic

Abstract

The invention discloses a kind of automobile corrugated pipe plastic. The automobile corrugated pipe plastic is characterized by comprising the following materials, by weight, 20-36 parts of PA6 resins, 1-6 parts of PP-g-MAH, 2-5 parts of expanded perlite powder, 3-7 parts of binders, 1-4 parts of methyl methacrylate, 2-6 parts of azodicarbonamide, 25-30 parts of polyvinyl ester, 14-20 parts of disebacate ester, 3-8 parts of carbon black, and 14-20 parts of dioctyl benzene dicarbonate. The plastic modified material has good heat resistance, and the thermal deformation temperature is above 95 DEG C. The plastic modified material has good cold resistance, and the brittleness temperature is subzero 50 DEG C. The plastic modified material has good performances of tensile strength and shock strength, and the automobile corrugated pipe prepared from the material has a long service life.

Description

technical field [0001] The invention relates to an automobile bellows plastic. Background technique [0002] The improvement of people's consumption ability has led to the rapid development of the automobile industry, among which the growth of passenger cars is particularly rapid. To resist extreme cold and extreme heat, but also to protect the safety of drivers and passengers. Automobile bellows are commonly used in automobiles. Previously, automobile bellows were mainly imported, with high cost and long production cycle; with the improvement of domestic auto parts manufacturing technology, and getting rid of the limitations of importing auto parts and engines, domestic experts and engineers A lot of research and technical improvements were done. [0003] Automotive corrugated pipes are used in automobile wiring harnesses, and plastic (PA, PE, PP, PVC) corrugated pipes are generally used. Each of the above-mentioned corrugated pipes has its own advantages and disadvantage...

AI Technical Summary

Problems solved by technology

[0003] Automotive corrugated pipes are used in automobile wiring harnesses, and plastic (PA, PE, PP, PVC) corrugated pipes are generally used. Each of the above-mentioned corrugated pipes has its own advantages and disadvantages. For example, PVC materials have poor heat resistance, while PP or PE materials The mechanical properties of the bellows made of PA are a little worse than those of PA bellows, but they are better than PA bellows in terms of product stability and water absorption.
