Abstract

The invention discloses a composite coating containing deodorizing module and a preparation method thereof. A fluffy porous material is used as a carrier; through the design of two coating solutions,the two coating solutions are sprayed onto two sides of the bulky porous material respectively to form a catalyst layer and an acidic deodorizing layer; the two coating solutions do not react with each other and can effectively exert the effect of removing alkali and acid odor gases; the catalyst layer can effectively remove acid gases such as sulfur dioxide, thiol substances such as methyl mercaptan and ethanethiol, and aldehyde pollutants such as formaldehyde and acetaldehyde; the acidic deodorizing layer can remove alkaline gases such as trimethylamine and ammonia gas; a material is endowedwith flame-retardant performance, and functional diversity and comprehensive improvement on the performance are achieved; on the other hand, through the optimization of components of the coating solutions, the performance of coating is stable, the activity decay is unlikely to occur, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of air purification filter materials, in particular to a deodorizing module with a composite coating and a preparation method thereof. Background technique [0002] The current spray-bonded cotton deodorization products have certain adsorption and chemical deodorization properties, and are mainly used in refrigerators to remove acidic and alkaline odorous gases in refrigerators, such as trimethylamine, ammonia, sulfur dioxide, etc. The structure of existing spray-bonded cotton deodorization products is as follows: figure 1 As shown, using glued cotton as a carrier, spray acidic deodorizing substances on both sides of the A and B sides of the glued cotton, such as potassium permanganate, boric acid, phosphoric acid, nitric acid, hydrochloric acid, oxalic acid, citric acid, hypochlorous acid, etc. , its purpose is to remove trimethylamine, ammonia and other alkaline odor gases; after drying the product, spray...
