Abstract

The invention discloses a thermoplastic light compound plate and the manufacturing method, characterized in that it comprises acupuncture fiber carpet dipped in double faced foam of thermoplastic glue liquid and thermoplastic glue liquid layer coated on the surface, the density of compound plate is 0.35-0.90g/cm3, the weight of fiber scattered in bunchiness is 15-45% of acupuncture fiber carpet. The merit of invention is very remarkable. Special super long fiber and bunchiness fiber with certain proportion are maintained in the material so that the mechanical performance of material can be improved. In addition, the material is provided with foam structure, very good effect of heat and sound insulation. The invention is also provided with environmental protection and recovery.

Description

technical field [0001] The invention relates to a thermoplastic light-duty composite board and a preparation process thereof. Background technique [0002] At present, the commonly used boards for domestic automotive interiors include polyurethane resin foam composite boards, thermoplastic hemp fiber composite boards, semi-cured cotton felt boards, PP wood powder boards, PS foam boards, etc. The characteristics of the above materials cannot fully meet the needs of automotive interior materials. Requirements, such as high thermal deformation temperature, high tensile, light weight, flame retardant, environmental protection and other characteristic indicators, the thermal deformation temperature of most materials is around 82 ℃, and the high tensile decorative parts are often obtained by increasing the material per unit area. Re-implementation, such as the thermoplastic hemp fiber composite sheet used for the roof of Liuqi heavy truck M333, in order to meet the 350mm deep draw...
