Background

With the rapid development of social economy in China, the problem of environmental pollution becomes an increasingly prominent contradiction in economic development. The high-intensity noise harms human bodies, causes fatigue, generates negative emotions, and even causes diseases in the aspects of nervous systems, cardiovascular systems, endocrine systems, digestive systems, vision and the like. Noise pollution, water pollution, air pollution and solid waste pollution are considered as four main environmental problems in the world, and are extremely harmful. Therefore, the prevention and control of noise has become one of the important problems to be solved urgently in the current social development.

The noise control method has two main aspects: one is to control the vibration source and the sound source; and secondly, the transmission of vibration and noise to the periphery is cut off. Controlling the vibration source is a radical method, but because many sound sources exist objectively, people focus on the control of the noise mainly on the transmission control. Currently, a common method of noise transmission control is sound absorption and sound insulation. The sound absorption is to adopt sound absorption materials and a sound absorption structure to reduce reverberant sound caused by reflection, thereby achieving the purpose of controlling noise; the sound insulation is that sound insulation materials or sound insulation structures are used for isolating or blocking the transmission of sound energy, and noise is isolated from a receiver so as to achieve noise prevention, control and control.

At present, for pipelines with large noise, such as drain pipes, exhaust pipes and the like, sound insulation treatment is generally carried out by wrapping coiled materials (such as EVA (ethylene vinyl acetate) foaming sound insulation heat preservation coiled materials disclosed in patent document CN 214574794U), although the mode can play a certain sound insulation effect, the mode is still not enough to meet the minimum requirement of civil building sound insulation design specifications, and meanwhile, the traditional sound insulation coiled materials also have the defects of weak waterproofness and poor vibration insulation effect, and the problems of dampness, cracking and the like are easy to occur after long-term use.
