Abstract

The invention provides an environment-friendly sand-p0lastic composite material. A nano negative ion activating material is dispersed in the sand-p0lastic composite material, so that the problem thata material loses the negative ion activating function as the negative ion generating material arranged on the surface of the material is easy to fall off and is worn and polluted in the prior art. Inaddition, according to the environment-friendly sand-p0lastic composite material provided by the invention, the functions of an existing sand-p0lastic composite material are expanded, and the application range of the sand-p0lastic 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 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 chem...
