Abstract

The invention provides a sand-plastic partition wall with a sound attenuation function. The sand-plastic partition wall comprises an outer plate, a plurality of first sound attenuation layers and an outer plate which are arranged sequentially, wherein the outer plate comprises the following raw materials in parts by weight: 25-35 parts of quartz sand, 5-7 parts of anion generating material, 15-20parts of polypropylene resin, 17-25 parts of polyethylene resin, 2-5 parts of couplant, 7-10 parts of silicon carbide whiskers, 10-15 parts of adhesive and 2-3 parts of surfactant, wherein the anion generating material comprises magnesia-alumina spinel and an anion excitation material loaded onto the magnesia-alumina spinel; and the adhesive is prepared from an epoxy resin adhesive, sodium carboxymethyl cellulose and aluminum sol.

Description

technical field [0001] The invention relates to the field of composite materials, and belongs to a sand-plastic partition wall which realizes gas purification and sound absorption by generating negative ions. Background technique [0002] As we all know, a lot of paint and adhesives are used in the process of house decoration, and paints and adhesives often contain a lot of formaldehyde. This will cause the formaldehyde content in the indoor air to exceed the standard, which will cause damage to the human body. At present, the methods commonly used to remove indoor formaldehyde harmful gases are mainly physical methods and chemical methods. Among them, the physical method is to use porous materials such as activated carbon to adsorb the indoor formaldehyde gas, so as to reduce the indoor harmful gas content. However, in this way, due to the limited adsorption capacity of activated carbon, the removal of formaldehyde is not ideal. The chemical method is mainly through the ...
