Abstract

The invention discloses a low-smell vehicle polypropylene composite material and its preparation method and is characterized in that the low-smell vehicle polypropylene composite material comprises the following components: by weight, 50-85% of polypropylene resin, 5-25% of a mineral filler, 0-20% of glass fiber, 0.6-4.5% of a smell absorption masterbatch, 0-1.5% of zinc ricinoleate, 0-2% of abietate, 5-15% of a flexibilizer, 0-1% of an anti-oxidant 1010, 0-5% of a toner, and other auxiliary agents. The polypropylene is one or a combination of co-polypropylene or high-crystallized homo-polypropylene with the crystallization degree being 50%-70%. The mineral filler is one or more of powdered steatile, calcium carbonate or mica powder. The anti-oxidant 1010 is tetra[beta-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester. The composite material provided by the invention has excellent comprehensive properties and has a characteristic of low smell grade.

Description

technical field [0001] The invention relates to a rubber and plastic material, in particular to a low-odor automotive polypropylene composite material and a preparation method thereof. Background technique [0002] With the development of the automobile industry, in addition to the gradual improvement in the performance of automobiles, consumers also have higher and higher pursuits for the appearance, comfort, and whether the car body is green, environmentally friendly, and healthy. Because the car body space is relatively closed, the volatile gas from the car body interior parts will directly affect the air quality in the car, especially at high temperature. Focusing on the problem of odor generated by automobile materials, at present, the industry basically adopts the method of adding odor adsorbents to plastic parts, and has achieved certain results. When selecting an adsorbent, due to the influence of various additives on the properties of the material, most of them are...
