Abstract

The invention provides a sand-plastic composite material. The sand-plastic composite material has the advantages that firstly, a negative ion generating material is dispersed into the sand-plastic composite material, so that the problems that in the prior art, the negative ion generating material which is arranged on the surface of the material easily falls off and is worn and contaminated and theefficiency of exciting negative ions, of the material, is lost are solved; in addition, by means of the environmentally-friendly sand-plastic composite material provided by the invention, the functions of a conventional sand-plastic composite material are extended and the usage range of the sand-plastic composite material is expanded.

Description

technical field [0001] The invention relates to the field of composite materials, and belongs to a sand-plastic composite material capable of purifying 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...
