Polypropylene honeycomb-core glass fiber polypropylene composite plate and manufacture method thereof

Abstract

The invention discloses a polypropylene honeycomb core glass fiber polypropylene composite board. The composite board is composed of a polypropylene glass fiber layer, a polypropylene honeycomb core and a polypropylene glass fiber layer laminated sequentially from bottom to top. The constituent materials of the composite board are in parts by weight, including 29.5 parts of polypropylene fibers, 35 parts of glass fibers, 0.5 parts of carbon black, and 35 parts of polypropylene honeycomb cores; the raw materials of the polypropylene honeycomb cores are in parts by weight, wherein 90 parts of polypropylene, 10 parts of low melting point polypropylene. The invention has the characteristics of heat aging resistance, permanent moisture resistance, mildew resistance and no peculiar smell, no deformation, no peculiar smell and no mildew after long-term use, low odor, low volatility and low VOC, the inner and outer materials are the same, the core layer and the The skin has good adhesion, high load-bearing strength, and high peeling strength. Leftovers and scrap products can be recycled directly, saving resources and meeting environmental protection requirements.

Description

technical field [0001] The invention relates to the technical field of composite new materials, in particular to a polypropylene honeycomb core glass fiber polypropylene composite board and a manufacturing method thereof. Background technique [0002] With the rapid development of the world economy and the steady improvement of people's living standards, automobiles, as a means of transportation in human society, bring people into a modern civilized society. The rapid development of the automobile industry has also led to the development of related industries, among which automotive interior materials are booming. Car interior is an important part of a car, and it is usually required to have the characteristics of beauty, softness, comfort, warmth, good elasticity, and no peculiar smell. [0003] At present, domestic automotive interior materials are mostly paper-core honeycomb boards, rigid polyurethane boards, hemp fiber boards or ABS boards, which are prone to mold and m...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic automotive interior materials are mostly paper-core honeycomb boards, rigid polyurethane boards, hemp fiber boards or ABS boards, which are prone to mold and mildew during the rainy season, brittle at low temperature is more serious, poor moisture resistance, and easy to deform when exposed to water; Moreover, in recent years, the emission of VOC in the car has attracted people's attention. VOC is an organic compound that is easy to volatilize at room temperature, including formaldehyde, toluene, styrene, etc.
