Abstract

The invention discloses a powdery tea leaf-based air purification filter membrane as well as a preparation method and application thereof. The air purification filter membrane comprises a membrane carrier and powdery tea leaves which are physically adhered to the surface of the membrane carrier, wherein the mass ratio of the membrane carrier to the powdery tea leaves is 1 : (0.2 to 15). The preparation method comprises the following steps: by taking clean fresh tea leaves without impurities as a raw material, crushing and sieving the clean fresh tea leaves, adding purified water, uniformly stirring to obtain tea leaf powder slurry, finally, enabling the tea leaf powder slurry to be uniformly dispersed on the surface of the membrane carrier through a physical method, and drying to obtain the powdery tea leaf-based air purification filter membrane. The invention provides a new use of the tea leaves, and by using the tea leaves as a functional matrix in air purification equipment, the powdery tea leaf-based air purification filter membrane has the characteristics of nature, safety, environmental protection and no pollution; the powdery tea leaf-based air purification filter membrane has the effects of adsorption, bacterium inhibition, deodorization and aroma enhancement, can also effectively purify air, improves the room environment, can expand the use of the tea leaves and increases the benefit of a tea farmer; and the raw materials used are easy to get and low-cost, the preparation method is simple, the actual application effect is remarkable, and important popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of application of air purification materials, more specifically, to a powdered tea-based air purification filter membrane and its preparation method and application. Background technique [0002] With the rapid development of global urbanization and industrialization, air pollution is one of the major problems facing all mankind. As far as our country is concerned, the pollution of fine particles in the air (PM2.5) and toxic volatile gases are the main sources of pollution. Studies have shown that fine particles in the air are one of the culprits that cause respiratory diseases, cardiovascular and cerebrovascular diseases and cancer. Therefore, to maximize the elimination and purification of fine particles and odors in the air, and to breathe pure air is a necessary condition for human survival. [0003] In the prior art, most of the core purification components of air purification equipment are composed o...
