Abstract

The present invention discloses a nanometer silver / polyurethane / polypropylene elastic composite sound-absorbing cotton, which is prepared from the following raw materials by weight: 10-15 parts of thermoplastic polyurethane, 30-40 parts of polypropylene, 3-5 parts of nanometer silver, 0.3-0.5 part of poloxamer, 0.5-1 part of isopropyl myristate, 0.1-0.2 part of lauryl dimethyl betaine, 3-5 parts of acetyl tributyl citrate, 0.1-0.2 part of an antioxidant 1010, 0.5-1 part of pullulan, and 10-15 parts of a modified silica gel solution. The nanometer silver / polyurethane / polypropylene elastic composite sound-absorbing cotton of the present invention has characteristics of effective medium-low frequency noise absorbing control, good sound absorption, excellent mechanical property, high stability and wide application range, and has the antibacterial and deodorization added value.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing materials, in particular to a nano-silver / polyurethane / polypropylene elastic composite sound-absorbing cotton and a preparation method thereof. Background technique [0002] With the continuous development of economy and urban construction, noise pollution is becoming more and more serious, which brings adverse effects on people's daily life and study. Reducing the harm caused by noise has become an important issue. People make sound-absorbing materials to prevent and control noise, so that the noise is isolated or weakened. Among them, porous materials have a wide range of sound-absorbing frequencies and are widely used. The characteristic of porous sound-absorbing materials is that the sound-absorbing performance of the high-frequency band is better than that of the low-frequency band, and it is difficult to block the middle and low-frequency noise. By changing the material properties, ...
