Polyurethane rubber sound and vibration insulation cushion and use method thereof
The invention relates to a polyurethane rubber sound and vibration insulation cushion which is mainly used for sound and vibration insulation of central air-conditioner rooms such as office buildings. The polyurethane rubber sound and vibration insulation cushion is characterized in that the vibration cushion is of an up-and-down double-layer structure, the upper layer is a surface layer (2), the lower layer is a bottom layer (1), the surface layer (2) and the bottom layer (1) are both made of waste polyurethane rubber particles, and multiple through holes (3) are evenly distributed in the bottom layer (1). The polyurethane rubber sound and vibration insulation cushion is prepared from the waste polyurethane rubber particles, the cost is low, a space net-shaped structure is formed after the particles are pressed, interspace is large, the elasticity is good, the sound absorption effect is good, and the vibration reduction effect is good; the through holes are additionally formed in the bottom layer, and the sound absorption effect and the vibration reduction effect are further improved; colorful waste polyurethane rubber particles are adopted by the surface layer, the distinguishing degree is high, and attractiveness is achieved; in addition, through holes are not formed in the surface layer, cement paste in concrete can be prevented from being poured, and the elasticity is guaranteed.
