Abstract

The invention discloses a novel material for a needled carpet of a car. The novel material is prepared by the following steps of: taking 38-42wt% of styrol elastomer (SBS) as a main formula; adding auxiliary materials including 8-1wt% of processing oil, 24-26% of polyethylene, 22-26wt% of filler and 1wt% of processing aid, mixing, and then extruding and pelleting. In the invention, the novel styrol elastomer is taken as a main material, therefore, the novel material has excellent performances such as recyclability, simple processing process, environment friendliness, favorable low-temperature resistance, wide hardness, light weight, comfortable handfeel, no stickiness on hands, sound-adsorption and shock-adsorption properties and the like.

Description

technical field [0001] The invention relates to the technical field of carpet materials, in particular to a novel needle-punched carpet material for automobiles. Background technique [0002] People place carpets in cars, which not only can play the role of decorating the car, but also play the roles of comfort, anti-skid and shock absorption. Among the existing automobile carpets, two kinds are widely used, namely, needle-punched carpets and tufted carpets. In the total consumption of car carpets in the world, tufted carpets account for 48% and needle-punched carpets account for 44%, that is to say, there is not much difference in market share between the two. Because needle-punched carpets have better anti-skid performance and are easier to clean, so The number of people who choose and buy is gradually increasing, and solving their comfort is the best improvement to increase their market share. [0003] Most of the research on needle-punched carpets for automobiles focus...
