Heat-resistant air conditioner sound insulation cotton

Abstract

The invention discloses heat-resistant air conditioner sound insulation cotton which comprises a hollow polyester cotton roll, a polypropylene layer and a non-woven fabric. The polypropylene layer isarranged on the surface of the hollow polyester cotton roll; the polypropylene layer and the hollow polyester cotton roll form a net structure; and the non-woven fabric is coated on the surface of thenet structure formed by the polypropylene layer and the hollow polyester cotton roll through colloid. According to the heat-resistant air conditioner sound insulation cotton, through melting and blowing polypropylene on the hollow polyester cotton roll, the strength of the sound insulation cotton is improved, so that the sound insulation cotton is not likely to break and age, good in weather resistance and long in service life during installation and use. The colloid is added between the non-woven fabric and the hollow polyester cotton roll, so that the stability of the produced sound insulation cotton structure is improved by more than 30%, the sound insulation cotton is more stable and durable, and the service life of the sound insulation cotton is effectively prolonged.

Description

technical field [0001] The invention relates to the field of air conditioner compressors, in particular to a heat-resistant air conditioner sound insulation cotton. Background technique [0002] Air-conditioning is a common household appliance, and noise is an important factor affecting the comfort index of air-conditioning and one of the important indicators for evaluating the quality of air-conditioning. It not only pollutes the surrounding environment, but also affects people's life and work. With the development of the economy and the continuous improvement of living standards, people have higher and higher requirements for the noise index of air conditioners. In addition to good performance and safety indicators, low noise is also one of the important indicators for improving the market competitiveness of air conditioners. The noise of the outdoor unit of the air conditioner mainly comes from the compressor and the fan. The motor of the compressor body emits medium and...

AI Technical Summary

Problems solved by technology

[0003] At present, the sound insulation cotton used to wrap the compressor in the prior art, the sound insulation layer and the sound absorption layer are stacked together by glue to form the sound insulation cotton. Considering the noise reduction effect, the material of the sound absorption layer is generally selected from non-woven fiber, but because of The tear strength is generally low. In the air conditioner production process, when wrapping the compressor, the gaps of the sound insulation cotton are often caused, such as pipe holes, incisions, edges and other parts, where local stress is too large, resulting in cracking of the sound-absorbing layer, which affects the aesthetics and sound absorption. reduce the appearance quality and noise reduction effect of the sound insulation cotton
