Abstract

The invention provides a polypropylene compound with anti-ash absorption and good appearance. The material includes the following raw material formula in parts by weight: polypropylene: 30-98 parts; polyethylene: 1-10 parts; propylene-based elastomer: 1-15 parts Dustproof agent: 0.2-2 parts; Processing oil substitute: 0.5-5 parts; Primary antioxidant: 0.1-0.5 parts; Secondary antioxidant: 0.1-0.5 parts; Light stabilizer: 0.1-0.5 parts. In the anti-soot absorption polypropylene compound with good appearance, the polyethylene is VLDPE, the propylene-based elastomer is ethylene-propylene copolymer, and the processing oil substitute is ethoxylated laurylamide polyethyleneamine aqueous solution. The invention adopts masterbatch technology, and avoids the use and precipitation of lubricants, processing oils and additives through the selection of raw materials, and prepares a polypropylene compound with anti-dust absorption and good appearance.

Description

technical field [0001] The invention belongs to the technical field of polypropylene materials, and in particular relates to a polypropylene composite with anti-ash absorption and good appearance and a preparation method thereof. Background technique [0002] Polypropylene has the advantages of low density, low price and easy processing. It has been widely used in automobiles, home appliances and other industries. However, parts made of polypropylene materials are particularly easy to absorb dust in the air when placed in the air. A layer of dust is formed, which is difficult to wipe off, for which modification in terms of resistance to ash absorption is required. [0003] The anti-ash absorption method currently used is mainly to add antistatic agents or conductive compounds. CN109867861A achieves dustproof effect by adding cage-type polysilsesquioxane and antistatic additives; patent 201810227583.X achieves antistatic effect by adding hyperbranched polyethyleneimine; pate...
