Abstract

The invention discloses a sound-absorption and flame-retardant automotive trim material and a preparation method thereof. Raw materials of the trim material comprise a polypropylene resin, an ABS resin, polymethyl methacrylate, a polyester fiber, a degummed jute fiber, barium sulfate, polyvinyl alcohol, arsenic trioxide, a flame retardant, a toughening agent and a silane coupling agent. The preparation method comprises the following steps: modifying the polyester fiber and the degummed jute fiber with the silane coupling agent, uniformly mixing the polypropylene resin, the ABS resin, the polymethyl methacrylate, the barium sulfate, the polyvinyl alcohol, the arsenic trioxide, the flame retardant, the toughening agent and the modified fibers by a high mixing machine, carrying out fusion ina screw extruder, and carrying out extrusion to obtain the trim material. The material not only greatly absorbs interior noise to improve the comfort in the automobiles, but also has favorable flame retardance and can improve the safety performance.

Description

technical field [0001] The invention belongs to the technical field of automotive interior materials, in particular to a sound-absorbing and flame-retardant automotive interior material and a preparation method thereof. Background technique [0002] The interior materials consumed by an ordinary family car are about 20-40kg. These decorations are mainly composed of flammable textiles, fiber lining boards, polyurethane foam, artificial leather, hot-melt adhesives and other materials. , and are mainly distributed in more than forty parts such as ceilings, door linings, carpets, seats, seat belts, sound insulation felts, luggage compartment liners, and sealing filter felts. During the transportation of automobiles, due to electrical short circuit, engine failure, traffic accidents and other reasons, it is very easy to cause fire, resulting in property loss and even casualties. However, flammable automotive interior decorations tend to aggravate the degree of fire in accidents....
