Technical Field

The invention relates to the field of soundproof cotton, in particular to a manufacturing method of heat-resistant soundproof cotton for an air conditioner.

Background

Noise is an environmental pollution, is considered as the third most serious public nuisance which is second only to air pollution and water pollution, brings great pain and serious harm to people in daily life, work, study and spirit, and is particularly harmful to children, old people, patients and heart disease patients. Various soundproof cotton materials are generally used in sound sources such as machines or noise transmission media in order to reduce the influence of noise. There are various soundproof cotton materials in the market at present, and this kind of product has played certain effect to the noise reduction, but because this kind of product used material and material structure are too single, can not play the better effect of making an uproar of falling, must have the soundproof cotton of multi-material multifunctional composite structure just can play good syllable-dividing effect.
