Abstract

The invention discloses a low-VOC low-odor environmental-friendly flame-resistant glass fiber reinforced PP composite material and a preparation method thereof. The material comprises, by weight, 30-75 parts of PP resin, 10-50 parts of glass fibers, 10-40 parts of environmental-friendly flame-resistant agent, 1-8 parts of compatilizer, 0.1-2.0 parts of absorbing agent, 0.1-2.0 parts of processing agent and 0.1-0.5 part of antioxidant. According to the low-VOC low-odor environmental-friendly flame-resistant glass fiber reinforced PP composite material and the preparation method thereof, the low-odor phosphorus and nitrogen halogen-free flame-resistant agent with big molecular weight and good heat stability is selected and used, the flame-resistant effect is good, and the mechanical property is good; the glass fiber are added, and the PP strength and heat-resistance temperature are improved; the volatile organic compound is removed effectively by adding the absorbing agent and inorganic nano-materials cooperating with a specific double vacuum technique, so that the modified polypropylene with high strength, good heat-resistant performance, low odor and low VOC is obtained; the low-VOC low-odor environmental-friendly flame-resistant glass fiber reinforced PP composite material can be formed by injection moulding and compression moulding; the requirements of the majority of automobile trim parts, especially the automobile trim of a school bus, with high flame-resistant requirement are met.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a low-VOC, low-odor, environmentally friendly, flame-retardant glass fiber reinforced PP composite material and a preparation method thereof. Background technique [0002] As a general-purpose plastic, polypropylene (PP) has light weight, excellent comprehensive performance, simple production process and wide application. It has become one of the fastest-growing plastics in general-purpose plastics. Although polypropylene has many advantages, due to its low oxygen index and flammability, its application in the fields of electronics, electrical appliances and automobiles has been greatly restricted. In recent years, the country has paid more and more attention to the flame retardancy of plastics, especially for plastic accessories used in household appliances, aviation, automobiles and other industries. [0003] In addition, polypropylene also has d...
