Waterproof and environment-friendly paper honeycomb composite board for automotive interior, and preparation method of composition board

Abstract

The invention discloses a waterproof and environment-friendly paper honeycomb composite board for automotive interior, and a preparation method of the composition board. The waterproof and environment-friendly paper honeycomb composite board is formed by compounding a piece of non-woven fabric, a hot melt adhesive membrane, a bamboo fiber felt, another hot melt adhesive membrane, a paper honeycomb core, another hot melt adhesive membrane, a GMT felt and another hot melt adhesive membrane from bottom to top; each hot melt adhesive membrane is prepared from the following raw materials in parts by weight: 20-30 parts of ternary co-polypropylene, 10-20 parts of a vinyl-propylene copolymer, 5-10 parts of C5 / C9 copolymer resin, 2-4 parts of high molecular weight polypropylene (PP) wax and 1-2 parts of an antioxidant; the bamboo fiber felt is prepared from the following raw materials in parts by weight: 40-50 parts of bamboo fiber, 5-10 parts of brucite powder, 5-8 parts of sepiolite powder, 10-15 parts of a urea-formaldehyde resin adhesive, 7-12 parts of silicone acrylic emulsion, 1-2 parts of nano titanium dioxide and 4-6 parts of castor oil. The waterproof and environment-friendly paper honeycomb composite board has the characteristics of being less in odor and less in volatile organic compounds (VOC), resisting low temperature and heat aging, being permanent in moisture resistance, mould-proof and free from undesirable odor, and the like, and is non-toxic and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of automobile interior decoration materials, in particular to a waterproof and environment-friendly paper honeycomb composite board for automobile interior decoration and a preparation 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 automobile interior materials are mostly rigid polyurethane boards, hemp fiber boards or ABS boards, which are p...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic automobile interior materials are mostly rigid polyurethane boards, hemp fiber boards or ABS boards, which are prone to mold and mildew during the rainy season, become brittle at low temperatures, have poor moisture resistance, and are easily deformed when exposed to water; The emission of indoor VOC has aroused people's great attention. VOC is an organic compound that is easy to volatilize at room temperature, including formaldehyde, toluene, styrene, etc.
