Problems solved by technology

[0003] In order to reduce the impact of noise, more sound insulation materials are used during decoration. The common sound insulation materials on the market are cement concrete, glass panels, etc. The sound insulation effect of these sound insulation materials is not very good, and these sound insulation materials are too heavy or thick. Inconvenient to install

Abstract

The invention discloses a soundproof material. The soundproof material comprises a first soundproof layer, a sound absorbing layer and a second soundproof layer. The first soundproof layer is prepared from polyethylene, polystyrene plastic, ethylene-propylene-diene rubber, steel slag powder, a wetting agent, a waterproof agent and an antioxidant. The sound absorbing layer is prepared from sound absorbing cotton, mineral cotton and glass fiber cotton felts. By sequential adhesion of the first soundproof layer, the sound absorbing layer and the second sound absorbing layer, great soundproof effects can be achieved, and the soundproof material is light in weight and convenient to mount.

Description

technical field [0001] The invention relates to a composite sound insulation material, which belongs to the field of building materials. Background technique [0002] Noise pollution is regarded as one of the three major environmental pollutions whose hazards are equal to air pollution and water pollution. Generally, noise exceeding 50 decibels will have harmful effects on human daily work and life, especially on sleep. Human beings spend nearly 1 / 3 of their time in sleep. Sleep is an important condition for human beings to eliminate fatigue, restore physical strength and maintain health. However, environmental noise can make people unable to sleep or be awakened. In this regard, the elderly and the sick are more sensitive to noise interference. When sleep is disturbed, work efficiency and health will be affected. Long-term sleep disturbance can cause insomnia, fatigue, memory loss, and neurasthenia syndrome. In residential environments, inter-floor noise is the most ann...
