Problems solved by technology

[0005] The sound-absorbing and shock-absorbing products used in existing automobile main carpets are generally divided into two types: cotton felt type and PU foam type; now, as the country has higher and higher requirements for the air quality in passenger cars, PU foam type The VOC value of the product has always been high; ordinary flat hot air felt products use fine denier fibers to meet the requirements of sound absorption and shock absorption, but the product has poor elastic recovery and does not have a good touch. poor effect

Abstract

The invention provides a composite sound insulation high-resilience automobile main carpet anti-vibration pad which comprises two horizontally laid sound absorbing layers and two vertically laid high-elasticity layers, wherein the sound absorbing layers and the high-elasticity layers are compounded into a whole in a staggered way; each sound absorbing layer has the square gram weight of 400-600g / m<2>, and each high-elasticity layer has the square gram weight of 1100-1300g / m<2>. The invention also provides a preparation method of the product. According to the automobile main carpet anti-vibration pad, the two horizontally laid sound absorbing layers and the two vertically laid high-elasticity layers are adopted, and the sound absorbing layers and the high-elasticity layers are compounded into a whole in a staggered way, so that the product is good in sound absorbing property and elastic recovery; furthermore, recycle cotton and a polyurethane (PU) foaming technology are not used, so that volatile organic compounds (VOC) are not produced, and the product is in accordance with the in-car air quality requirement of a passenger car in China and is non-toxic.

Description

technical field [0001] The invention relates to a shockproof pad and a manufacturing method thereof, in particular to a composite sound-insulating high-resilience automobile main carpet shockproof pad and a manufacturing method thereof. Background technique [0002] Carpet is a floor covering made of cotton, linen, wool, silk, grass and other natural fibers or chemical synthetic fiber materials, which are knitted, tufted or woven by hand or mechanically. It is one of the arts and crafts categories with a long history and tradition in the world. Covering the ground of residences, hotels, gymnasiums, exhibition halls, vehicles, ships, aircraft, etc., it has the effects of noise reduction, heat insulation and decoration. There are many ways to classify carpets. According to the manufacturing process, there are hand-tufted carpets, hand-woven plain weave carpets, hand-tufted carpets, hand-made felt blankets, and machine-made carpets; There are wool carpets, silk carpets, jute ...
