Abstract

The invention discloses a little-odor and few-VOCs (volatile organic compounds) automotive paper honeycomb composite board, which comprises a paper honeycomb core layer, hot melt adhesive film layers, a non-woven fabric layer and a surface layer material, wherein the hot melt adhesive film layers are adhered to the upper surface and the lower surface of the paper honeycomb core layer; the non-woven fabric layer is adhered to the surface of a hot melt adhesive film; the surface layer material covers the non-woven fabric layer; the paper honeycomb core layer has a honeycomb-shaped structure consisting of hexagonal hole grids and triangular hole grids; a dentate adhering structure is formed between the surface layer material and the non-woven fabric layer; the hot melt adhesive film is prepared from the following raw materials of polyneopentylene-1,6-hexamethylene adipate glycol, a polyoxyethylene-polystyrene-polyoxyethylene triblock copolymer, polyethylene acrylate, pentaerythritol, neopentyl glycol, hexadecanoic acid, lauryl-L-glutamic acid-[alpha],[gamma]-dibutylamine, zinc ricinoleate, 2,5-dimethyl-2,5-di-(tert-butylperoxy)acetylene, a hydroxyketone photoinitiator and the like. The little-odor and few-VOCs automotive paper honeycomb composite board is little in odor; the VOCs are below a standard limit minimum.

Description

technical field [0001] The invention relates to a paper honeycomb composite board for automobiles, in particular to a low-odor and low-VOC paper honeycomb composite board for automobiles and a dry forming process thereof. Background technique [0002] Paper honeycomb composite board has the characteristics of high strength, light weight, and easy molding. In recent years, it has been widely used in automotive interior parts such as spare tire covers, coat racks, and sunroof sliders. It has gradually replaced traditional wood powder boards, GMT boards, and wood boards. and other materials. In recent years, the emission of VOC in the vehicle interior has aroused great concern. VOC is an organic compound that is easy to volatilize at room temperature. Well-known varieties include formaldehyde, toluene, and styrene. The main source of VOC in the car is produced by the volatilization of various parts. The main volatilized interior materials include plastic parts, foam, leather ...
