Composite interior material for motor car and preparation method thereof

Abstract

The invention relates to a composite interior material for a motor car and a preparation method thereof. The composite interior material comprises 60-80% of high performance fibers, 10-20% of flame retardant fibers and 10-20% of hot-melt fibers; and the preparation method comprises the following specific steps of: 1) opening the high performance fibers, the flame retardant fibers and the hot-melt fibers by a bale opener; reopening the high performance fibers, the flame retardant fibers and the hot-melt fibers by using a rough opener; and then mixing the high performance fibers, the flame retardant fibers and the hot-melt fibers by using a cotton blending machine; finely opening the mixture by using a fine opener; and combing the mixture by using a carding machine; 2) by using a nonwoven needle-punched machining technology, lapping the combed fibers in a cross way by a lapping machine; and then carrying out needle punching on the fibers by using a needle machine; and processing the fibers by using a singeing machine and a glazing calendar; and 3) carrying out composite hot pressing on a fiber felt which is a needle-punched, singed and calendared semi-finished product; and finally, forming the composite interior material together with a thermoplastic resin.

Description

technical field [0001] The invention relates to a composite interior decoration material and a preparation method thereof, in particular to a composite interior decoration material used in motor vehicles and a preparation method thereof. Background technique [0002] In recent years, the rapid development of high-speed trains and the rapid increase in the demand for high-end car interior materials, but as a major consumer of vehicle interior materials, there is almost no research and development of high-end interior materials. High-end automotive interior materials need to have high resilience, color fastness to sunlight and heat, and abrasion resistance of more than 10,000 times, and have strict safety indicators. At present, there is no corresponding general-purpose product, and customized products cannot meet the corresponding requirements in terms of the above-mentioned performances. The general composite interior materials have relatively low strength, flame retardant, ...
