Abstract

The invention discloses a breathable, environment-friendly and sound-absorbing material for decoration and a preparation method thereof. 9-21 parts, bamboo charcoal powder 7-20 parts, adhesive resin 7-18 parts, molybdenum disulfide 13-24 parts, prickly pear extract 12-25 parts, polyester fiber 7-23 parts, polyurethane 9-21 parts, 4-9 parts of antioxidant, 6-17 parts of film-forming aid, 4-11 parts of defoamer, 30-45 parts of water. The present invention has the following advantages: (1) The air-permeable, environmentally friendly and sound-absorbing material for decoration prepared by the present invention has good air permeability, and can adjust the indoor humidity in hot summer weather to make the human body feel comfortable; The breathable and environmentally friendly sound-absorbing material can continuously release negative ions and increase the content of negative ions in the room, which is beneficial to human health; (3) The breathable and environmentally friendly sound-absorbing material for decoration prepared by the present invention has good noise reduction and sound absorption effects, can effectively absorb external noise, and is beneficial human health.

Description

technical field [0001] The invention relates to the field of interior decoration materials, in particular to a breathable and environmentally friendly sound-absorbing material for decoration and a preparation method thereof. Background technique [0002] With the development of industry, the impact of noise pollution on the lives of urban residents is becoming more and more serious. Therefore, more families prefer to use sound-absorbing materials in interior decoration. Sound-absorbing material: Any material can absorb sound, but the degree of absorption is very different. Generally, materials with an average sound absorption coefficient of more than 0.2 for the above six frequencies are listed as sound-absorbing materials. Sound-absorbing materials Most of the sound-absorbing materials are loose and porous materials, such as slag wool, blankets, etc. The sound-absorbing mechanism is that sound waves penetrate into the pores of the material, and the pores are mostly open ho...
