Abstract

The invention relates to a low-odor polypropylene compound and a preparation method thereof. A low-odor polypropylene composite material incorporating a three-component stabilizer system formulated from the following raw materials in weight percent (%): polypropylene 55-95, talc 0-40, fatty acid ester compound 0.5-3, nano zinc oxide 0.5-3, nano titanium dioxide 0.5-3, heat stabilizer DSTP 0.1-1.0, heat stabilizer 31140.1-1.0, heat stabilizer 6180.1-0.5, wherein the fatty acid ester compound is carbon Long-chain fatty acid esters with carbon atoms in the chain between 25-45; the heat stabilizer DSTP is octadecyl thiodipropionate; the heat stabilizer 3114 is 3,5-di-tert-butyl-4 -Diethyl hydroxybenzyl phosphate; heat stabilizer 618 is dioctadecyl pentaerythritol bisphosphite. The invention has the characteristics of simple preparation process, low cost, excellent physical and chemical comprehensive properties, excellent odor characteristics and the like.

Description

technical field [0001] The present invention relates to a low-odor polypropylene compound, and more particularly relates to preparing a low-odor polypropylene compound by adding a multi-component odor suppressant system that can effectively suppress the unpleasant smell in the polypropylene compound material. Acrylic composite. The invention also relates to a method for preparing the composite material. Background technique [0002] In recent years, due to the rapid development of engineering modification technology of polypropylene materials, its application in the automotive field has become more and more extensive. However, as an important part of engineered polypropylene materials in the automotive field, various automotive interior parts made of engineered polypropylene materials, although they can meet the corresponding requirements in all aspects of performance, However, due to the fact that these materials emit certain unpleasant odors to varying degrees, they have...
