Abstract

The invention discloses a piece of sound insulation noise reduction wall paper and a preparation method thereof. The piece of wall paper comprises a substrate layer, a sound insulation noise reduction coating layer on the substrate and a pattern layer printed on the sound insulation noise reduction coating layer, wherein the substrate layer is a piece of high filled composite paper and comprises the ingredients by weight percent: 75-85% percent of calcium carbonate, 0-5% percent of calcium metasilicate and 10-25% percent of polyethylene; and the sound insulation medium in the sound insulation noise reduction coating layer is aluminum powder, iron powder or the mixture powder of the aluminum powder and the iron powder. The preparation method of the wall paper comprises the following steps: adopting the high filled composite paper as the substrate; coating the coating layer material consisting of the aluminum powder, the iron powder or the mixture powder of the aluminum powder and the iron powder so as to obtain the sound insulation noise reduction coating layer; and adopting the rotary screen printing to manufacture the wall paper with the function of sound insulation and noise reduction. The wall paper prepared by using the method integrates the decoration attractiveness of the wall paper and the function of a sound insulation noise reduction material, and is lower in polymer content, so that the wall paper is an environmental-friendly, ecological and healthy wall paper and can be widely applied to public places such as hotels, entertainment venues, airports, shopping malls, schools, kindergartens, hospitals, supermarkets and the like, and high-rise building decoration as well.

Description

technical field [0001] The invention belongs to the field of sound-proof and noise-reducing wallpaper and a preparation method thereof, and in particular relates to a sound-proof and noise-reducing wallpaper and a preparation method thereof. Specifically, it is to provide a kind of highly filled synthetic paper as the base material, which is coated with a cheap non-toxic, non-radioactive metal powder sound insulation and noise reduction coating with noise reduction function on the surface of the base material by coating method, and adopts rotary screen printing Ways to manufacture wallpapers with sound insulation and noise reduction functions. Background technique [0002] With the improvement of people's living standards, especially the quality of life requirements, the attention paid to the living environment is getting higher and higher. After air pollution and water pollution, noise pollution (noise generated by gas disturbance, noise generated by solid vibration, liquid...
