Abstract

The invention provides a sand-plastic composite material with the effect of scavenging formaldehyde gas. Through dispersion of a negative ion exciting material in the sand-plastic composite material,the problem that in the prior art, the material loses the effect of exciting negative ions because a negative ion generating material is easy to shed off and is easy to wear and polluted due to arrangement on the surface of the material is solved. In addition, according to the sand-plastic composite material with the effect of scavenging the formaldehyde gas, the functions of the conventional sand-plastic composite material are expanded and the application range of the sand-plastic composite material is broadened; in the sand-plastic composite material, a rubber adhesive comprising an epoxy resin adhesive, sodium carboxymethyl cellulose and an aluminum sol is further added, and the components are compounded with quartz sand, polypropylene resin and polyethylene resin for use, so that the hardness of the sand-plastic composite material can be effectively improved.

Description

Technical field [0001] The invention relates to the field of composite materials, and belongs to a sand-plastic composite material for purifying formaldehyde gas by generating negative ions. Background technique [0002] As we all know, a lot of paints and adhesives are used in the process of house decoration, and the paints and adhesives often contain a lot of formaldehyde. This will cause the indoor air formaldehyde content to exceed the standard, resulting in damage to the human body. At present, the commonly used methods to remove harmful indoor formaldehyde gas are mainly physical methods and chemical methods. The physical method is to use porous materials such as activated carbon to adsorb formaldehyde gas in the room to reduce the harmful gas content in the room. But this method, due to the limited adsorption capacity of activated carbon, the removal of formaldehyde is not ideal. Chemical methods are mainly through the use of chemical reagents such as formaldehyde scave...
