Abstract

The invention relates to the technical field of automotive upholsteries and specifically relates to a preparation method for a soundproof pad of an automobile carriage. The preparation method comprises the following steps: (1) mixing the raw materials of each layer: directly mixing the raw materials of each layer in parts by weight, wherein the soundproof pad comprises a first decorative layer, afirst soundproof layer, a mixed traditional Chinese medicine layer, a second soundproof layer and a second decorative layer which are arranged from bottom to top in turn, and the mixed traditional Chinese medicine layer is mainly prepared from purple perilla, elderberry, padus maackii, Chinese honey locust, peach leaves, cucumber, oleander leaves, foxglove, clove, musk, artemisia argyi and cattail; 2) injecting into a mould; 3) assembling the mould and molding. The soundproof pad is in light weight, has an excellent soundproof effect and is capable of effectively expelling and killing mice, cockroaches, ants, and the like; the soundproof pad has a certain sterilizing and insecticidal effect; the service life of the soundproof pad is obviously prolonged; the soundproof pad is environment-friendly and recyclable; the preparation method is simple and easy for production.

Description

technical field [0001] The invention relates to the technical field of automobile interior parts, in particular to a preparation method of an automobile compartment sound insulation pad. Background technique [0002] Car sound insulation pads can be applied to various parts of the car engine compartment, passenger compartment, trunk, etc., and have the characteristics of shock absorption, sound absorption, and heat insulation. The interior, like the appearance of the car, has become an important factor for people to choose a car, so the requirements for the interior parts of the car are getting higher and higher. At present, car sound insulation mats are mainly made of recycled fiber felt and PU foam, but because the location of car sound insulation mats is particularly suitable for mice, cockroaches, ants, etc., the service life of car sound insulation mats is not long, and bacteria breeds and produce unpleasant smells smell. Because the function of the existing automobil...
