Abstract

The invention provides a sand-plastic floor with an effect of purifying indoor air. The floor comprises a sand-plastic plate and a bottom plate, and further comprises a rubber layer, wherein the rubber layer is disposed between the sand-plastic plate and the bottom plate, and the rubber layer is provided with a plurality of air holes; the sand-plastic plate includes, by weight, the following raw materials: 25-35 parts of quartz sand, 1-3 parts of negative ion activation materials, 15-20 parts of polypropylene resin, 17-25 parts of polyethylene resin, 2-5 parts of a coupling agent, 10-15 partsof an adhesive, and 2-3 parts of a surfactant; and the adhesive is composed of an epoxy resin adhesive, sodium carboxymethylcellulose, and alumina sol.

Description

technical field [0001] The invention relates to the field of composite materials, and belongs to a sand-plastic board capable of purifying formaldehyde gas 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 use of chemical reagents...
