Abstract

The invention relates to a low-TVOC (total volatile organic compound) long glass fiber reinforced polypropylene material for an automotive trim and a preparation method of the material. The material comprises, by weight, 30-50 parts of glass fiber yarns, 100 parts of polypropylene resin, 2-8 parts of antioxidants, 1-3 parts of light stabilizers, 0-5 parts of flexibilizers, 0.5-5 parts of crosslinking agents and 0.5-5 parts of adsorbents. The long glass fiber reinforced polypropylene material has the characteristic of low TVOC, is simple in process and meets the requirements of practical production. The requirements of broad consumers for continuous improvement of in-car air quality are further met, and development of green environment-friendly materials in automobile industries in China ismore effectively pushed.

Description

technical field [0001] The present invention relates to a low TVOC long glass fiber reinforced polypropylene material for automobile interior decoration and its preparation method, in particular to a kind of low TVOC polypropylene resin and adding adsorbent, controlling the processing temperature and combining post-treatment baking material The process removes volatile small molecular organic compounds, thereby preparing long glass fiber reinforced polypropylene materials with low TVOC. Background technique [0002] Long glass fiber reinforced polypropylene materials have received more and more attention in the automotive industry. Compared with short fiber reinforced polypropylene, they have higher tensile, flexural strength and modulus, which will help realize the use of polypropylene general plastics in automobiles. It is widely used in industrial bearing parts and has become one of the popular materials for automobile lightweight. The long glass fiber reinforced polypro...
