Abstract

The invention discloses a low-gloss polyolefin elastomer composite material and a preparation method thereof. The low-gloss polyolefin elastomer composite material is composed of polypropylene, polyethylene, a delustering agent, a toughening agent, an antioxidant, a lubricant, a light stabilizer and an aid. The composite material disclosed by the invention has the characteristics of low surface gloss, good toughness, excellent heat resistance and the like, the raw materials are easily available, and the cost is low; and moreover, toxic and harmful substances such as vulcanizing agent and a vulcanizing aid are not added, secondary pollution is avoided, the preparation technology is simple, and the production cost is low.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a low gloss polyolefin elastomer composite material and a preparation method thereof. [0002] technical background [0003] Polypropylene (PP) material has excellent heat resistance, good bending fatigue resistance, low price and wide application, but PP has poor low temperature toughness. In order to improve the toughness of polypropylene, copolymerized polypropylene is prepared by copolymerizing ethylene and propylene. Copolymerized polypropylene generally contains 1%-7% by weight of ethylene molecules and 99%-93% by weight of propylene molecules. On the polymer chain, ethylene molecules are inserted in the middle of propylene molecules in a random and block manner, which improves the toughness of polypropylene. However, the toughness of copolymerized polypropylene is much worse than that of elastomers. For special application environments, ...
