Abstract

The invention relates to an inner trim board for a motor car and a preparing method of the inner trim board. The inner trim board is of a five-layer structure formed through fiber opening, carding, composite net laying and puncture. The first layer is a nylon fiber layer. The second layer is an activated carbon fiber layer. The third layer is a kapok fiber layer. The fourth layer is an activated carbon fiber layer. The fifth layer is a nylon fiber layer. An inner trim board product capable of being used for the motor car is manufactured through the working procedures of singeing, flame retardant treatment liquid immersion, drying and hot rolling. The prepared inner trim board product has the advantages of being high in strength, insulating from sound and capable of absorbing sound, adsorbing formaldehyde and odor smells, preserving heat, retarding flames and the like and meeting the requirements of the motor car for safety and functionality of the inner trim board.

Description

[0001] Technical field: [0002] The invention relates to an interior trim panel for motor vehicles and a preparation method thereof, in particular to a multilayer interior trim panel for motor vehicles and a preparation method thereof. Background technique: [0003] With the rapid development of EMUs in my country, with an average annual growth rate of 72.3%, the localization of EMUs has reached more than 75%, so the demand for EMU interior panels has increased rapidly. Motor car interior panels have high requirements on materials, which need to have functional characteristics such as sound insulation, sound absorption, and heat preservation on the basis of high strength, and have safety characteristics such as flame retardancy. At present, most interior trim products are mainly aimed at automobiles, such as automotive interior trim and its production method (CN200610168547), automotive interior parts with multi-layer structure (CN200680005411), its sound insulation, hea...
