Problems solved by technology

However, since most of the film-forming substances of coatings are organic polymers, traditional photodegradants still cannot avoid the problems of film-forming substances being degraded and low catalytic efficiency. In addition, TiO2-based photodegradable materials can only It has high efficiency and low efficiency under visible light, which is one of the reasons that limit its wide application

Embodiment 1

[0027] Add 5 parts of 1% graphene oxide aqueous solution to 50 parts of water, stir evenly, slowly add 4 parts of butyl titanate dropwise, continue stirring at 30°C for 2-3 hours after the dropwise addition, then add 3 parts of template agent P123 to dissolve in 80 parts of aqueous solution, after mixing, add hydrochloric acid to a concentration of 1-2M, then dropwise add 8 parts of tetraethyl orthosilicate, react at 40°C for 15h after the dropwise addition, then raise the temperature to 95°C and age for 30h to obtain a black mixture . The black mixture was filtered and dried at 60° C. for 10 h to obtain a gray-black solid. The solid was burned at 500° C. for 5 h under the protection of an inert gas to remove the template to obtain the TiO2 immobilized graphene-modified mesoporous amphiphilic composite material M1.

Embodiment 2

[0029] Add 10 parts of 1% graphene oxide aqueous solution to 80 parts of water, stir evenly, slowly add 5 parts of isopropyl titanate dropwise, continue stirring at 40°C for 2 hours after the dropwise addition, then add dropwise 4 parts of template agent F127 to dissolve in 70 parts of aqueous solution, after mixing, add hydrochloric acid to a concentration of 1-2M, then dropwise add 9 parts of butyl orthosilicate, react at 40°C for 15h after the dropwise addition, then raise the temperature to 120°C and age for 20h to obtain a black mixture . The black mixture was filtered and dried at 100° C. for 5 h to obtain a gray-black solid. The solid was burned at 500° C. for 10 h under the protection of an inert gas to remove the template to obtain the TiO2 immobilized graphene-modified mesoporous amphiphilic composite material M2.

Embodiment 3

[0031] Add 15 parts of 1% graphene oxide aqueous solution to 50 parts, stir evenly, slowly add 5 parts of titanium tetrachloride dropwise, continue stirring at 40°C for 3 hours after the dropwise addition, then add dropwise 4 parts of template agent P123 to dissolve in 100 parts of aqueous solution, after mixing, add hydrochloric acid to a concentration of 1-2M, then dropwise add 8 parts of methyl orthosilicate, react at 40°C for 20h after the dropwise addition, then increase the temperature to 80°C and age for 48h to obtain a black mixture . The black mixture was filtered and dried at 80° C. for 6 h to obtain a gray-black solid. The solid was burned at 500°C for 6 hours under the protection of an inert gas to remove the template to obtain the TiO2 immobilized graphene-modified mesoporous amphiphilic composite material M3.

Abstract

The invention discloses an air purification coating additive and a preparation method and application thereof in the technical field of chemical coatings. The air purification coating additive is prepared from, by weight part, 5-20 parts of 1% graphene oxide aqueous solution, 4-5 parts of titanium source, 8-12 parts of silicon source, 3-5 parts of template and 130-150 part of distilled water. The air purification coating additive can degrade organic pollutant and is amphiphilic, and accordingly can be stably dispersed in oil systems as well as aqueous systems; by immobilizing TiO2 into graphene oxide modified mesoporous amphiphilic composite materials, the dispersibility of the TiO2 can be enhanced, and meanwhile, due to the large surface area of graphene and mesoporous silicon dioxide, formaldehyde and organic matter absorption capacity can be greatly improved; hydrophobicity of the graphene enhances surface distribution of the air purification coating additive in coating films, accordingly greatly improves the probability of contact with the organic pollutant and further improves the degradation efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a coating additive capable of purifying air, a preparation method and application thereof. Background technique [0002] In recent years, the problem of environmental pollution has become more and more serious, and the research on semiconductor photodegradation of organic pollutants has attracted more and more interest, especially TiO2 photocatalyst. TiO2 has the advantages of high catalytic activity, good stability, ability to degrade organic pollutants, and low cost and non-toxicity. Therefore, it is widely used in medical disinfection, domestic wastewater and industrial wastewater treatment, architectural functional coatings, interior decoration materials, and solar cells field has been widely used. However, in the application of coatings, due to the strong photocatalytic activity of TiO2, the film-forming material is easily degraded. In addition, the addition of na...
