Problems solved by technology

At the same time, we found that after the material was added with activated carbon as an adsorbent, due to the uneven distribution of micropore size in the activated carbon, the difference was huge, and the largest pore size was as large as about 1000 angstroms, so other medium molecular weight additives added at the same time were often added together. Adsorption, which in turn affects other properties of the material, such as thermo-oxidative stability, etc.
Therefore, this method has little practical value

Abstract

A polypropene composition with low odor and low volatile components is proportionally prepared from polypropene, talc powder, fine-porous silica gel, toughening agent poe, thermal stabilizer DSTP, thermal stabilizer 3114 and thermal stabilizer 618 through mixing, dual-screw extruding out and granulating.

Description

technical field [0001] The present invention relates to a polypropylene composite material with low odor and low volatile content, and more specifically relates to adding an odor inhibitor which can effectively suppress the unpleasant smell in the polypropylene composite material and reduce the volatile content in the polypropylene composite material, Thus a low-odor, low-volatile polypropylene composite material is prepared. 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, Howev...
