Abstract
The application relates to the field of decoration materials, and specifically discloses a sound-absorbing and noise-reducing interior decoration material and a preparation method thereof. A sound-absorbing and noise-reducing interior decoration material, prepared from the following raw materials in parts by weight: 30-50 parts of polyvinyl chloride resin; 7-12 parts of styrene-methylstyrene copolymer; 2-3.5 parts of reinforcing fiber ; Plasticizer 6~10 parts; Antioxidant 0.8~1.3 parts; Stabilizer 1.5~2 parts. The preparation method is as follows: mixing and stirring the raw materials in advance to obtain a mixture, and then kneading to obtain kneaded flakes, and then vulcanizing molding to obtain a sound-absorbing and noise-reducing interior decoration material, which has the ability to improve the impact resistance of polyvinyl chloride resin, The advantages of maintaining good sound absorption and noise reduction capabilities.
Description
technical field [0001] The application relates to the field of decoration materials, more specifically, it relates to a sound-absorbing and noise-reducing interior decoration material and a preparation method thereof. Background technique [0002] Modern life pays more and more attention to the health of the indoor environment, and the indoor noise reduction effect directly affects the quality of life. The indoor noise reduction treatment is mainly to confine the noise in a small space, or absorb the noise, so as to provide a comfortable acoustic environment; Indoor noise reduction methods are generally divided into sound insulation and sound absorption. Sound insulation is to use dense materials to isolate sound waves from the outside. . [0003] For sound absorption and noise reduction, people generally install sound-absorbing panels indoors, such as high-density foam boards and sound-absorbing cotton panels, and the installation of sound-absorbing panels generally uses l...
