Abstract

The invention discloses an environment-friendly sound-insulating interior building material. The environment-friendly sound-insulating interior building material comprises the following raw materials in parts by weight: 5-7 parts of polyvinyl acetate, 6-10 parts of polyvinyl alcohol, 4-8 parts of silica sol, 7-9 parts of a water-soluble polyurethane solution, 4-6 parts of nanometer carbon black, 15-17 parts of sound-insulating fiber, 10-16 parts of broken glass powder, 8-14 parts of glass microbeads, 5-9 parts of enhanced oxide, 7-9 parts of calcium carbonate powder, 8-12 parts of a compound flame-retardant additive, 25-35 parts of a mineral filler and 2-6 parts of a sterilizing additive. The environment-friendly sound-insulating interior building material has relatively good worm-proof, sterilizing, sound-absorbing and sound-insulating performance, and has relatively strong advantages in aspects of the uniformity, the breathability, the tensile strength, the elastic recovery rate and the heat-insulating function; meanwhile, the environment-friendly sound-insulating interior building material uses safe and reliable components as raw materials, is free of environment pollution, relatively low in cost and concise in process, and has a relatively high practical value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of building sound insulation materials, in particular to an environment-friendly sound insulation material for building interior decoration and a preparation method thereof. Background technique [0002] With the continuous acceleration of urbanization, noise pollution is becoming more and more serious. In order to effectively cut off noise, the usual solution is to use soundproofing materials. Existing sound insulation materials are generally cement concrete, glass plates, etc., and the sound insulation effect of these sound insulation materials is not very good, so the usual solution is to increase the thickness of the sound insulation materials. The problem caused by this is that the quality of the sound insulation material is too heavy, the cost is too high, and the installation process is very inconvenient. [0003] On the other hand, sound insulation materials are divided into: sound insulation mater...
