Abstract

A preparation method of a tourmaline-based negative ion air-purifying functional composite filter material relates to the field of preparation methods of a composite filter material with an air-purifying function. First, the tourmaline and an adsorptive auxiliary agent A are stirred and mixed to obtain a mixed powder B. Then mix the mixed powder B with dispersant C and binder D to form a homogeneous solution E, and finally spray the homogeneous solution E on the glass fiber base cloth or non-woven fabric, and spray the glass fiber base cloth Or dry the non-woven fabric to obtain the tourmaline-based negative ion air-purifying functional composite filter material. The tourmaline-based negative ion air-purifying functional composite filter material prepared by the invention can simultaneously release negative ions beneficial to human health, absorb and degrade harmful pollutants in the air, and finally realize collaborative purification of air pollutants.

Description

technical field [0001] The invention relates to the field of preparation methods of composite filter materials with air purification function, in particular to a preparation method of tourmaline-based negative ion air purification functional composite filter materials. Background technique [0002] According to the standards of the World Health Organization (WHO), air pollutants refer to some harmful particles that remain in the atmosphere for a short time, including ozone, black carbon, dust, methane, bacterial microorganisms, etc. These pollutants are generally not easy to be detected, but they are the culprits that directly lead to cardiovascular and respiratory diseases, and are extremely harmful to human health. [0003] Traditional filter materials generally only filter dust, have no effect on harmful gases, and have limited ability to remove microorganisms. Therefore, the development and application of antibacterial and deodorizing materials is particularly important....
