Anti-sticking polypropylene composite material and preparation method thereof

Abstract

The invention provides an anti-sticking polypropylene composite material and a preparation method thereof. Small organic molecules, oligomers and other substances do not migrate to the material surface, thus preparing the anti-sticking polypropylene composite material. The invention also relates to a preparation method of the polypropylene composite material. The invention is used for improving the following technical problems: when automobiles are used under a higher temperature, the surfaces of polypropylene interior decorating materials may be sticky and unsmooth, thus affecting the comfort; and meanwhile, much flying dust can adhere to the surfaces of the interior decorating materials, so that the interior decorating materials become more difficult to clean. The key point of the technical solution is to provide the anti-sticking polypropylene material. Stronger basicity and larger specific surface area of the anti-sticking polypropylene material are utilized. More specifically, the anti-sticking polypropylene composite material is prepared by adding an anti-sticking agent. Meanwhile, the invention also discloses a preparation method of the polypropylene material. The anti-sticking polypropylene composite material is mainly applied to interior decorative parts of automobiles.

Description

technical field [0001] The present invention relates to an anti-adhesive polypropylene composite material, and more specifically relates to adding a kind of inorganic rigid particles that absorb oily substances such as small organic molecules and oligomers so that these oily substances do not migrate to the material. The surface is thus prepared as a non-adhesive polypropylene composite. [0002] The invention also relates to a method for preparing the polypropylene composite material. Background technique [0003] Polypropylene resin has excellent properties, such as low density, high strength, good high temperature resistance, and its low price and economy make it widely used in the automobile industry. The amount used in automobiles can reach 30kg- 50kg, and there are dozens of types of parts, mainly body interior parts, ventilation and heating system parts, engine-related parts and exterior parts. Especially for automotive interior systems, although polypropylene mater...
