Abstract

The invention discloses a low-density low-VOC scraping-resistant modified polypropylene composite material and a preparation method thereof. The composite material consists of the following raw materials in parts by weight: 60-80 parts of polypropylene, 15.5-31 parts of a toughening-VOC adsorption compound additive, 1-2 parts of a scraping agent, 0.02-0.05 part of an antioxidant and 2-4 parts of pure water. The toughening-VOC adsorption compound additive consists of the following raw materials in parts by weight: 3-8 parts of ethylene-octene copolymer (POE), 1 part of a compatilizer, 1 part ofa coupling agent, 0.5-1 part of nano vermiculite and 10-20 parts of diatomite with micropores in the surface. The composite material has low density, low VOC and high scraping resistance, and is suitable for automotive trim.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a PP composite material and a preparation method thereof. Background technique [0002] Automobiles are one of the most important means of transportation in modern society. With the development of society, automobile materials are required to have the characteristics of light weight, simple processing, and easy recycling. Polypropylene is a general-purpose thermoplastic with excellent comprehensive properties. It has the characteristics of low price, light weight, solvent resistance, good elasticity, rigidity, easy recycling, and non-toxicity. It is an important lightweight material for automobiles and is widely used in the field of auto parts. used widely. [0003] At present, with the continuous change of consumption concepts, people have put forward higher requirements for the aesthetics, comfort, and environmental protection of automotive interior parts, especially for the s...
