specific Embodiment 1

[0024] The photocatalytic environment-friendly nano-ceramic coating of the present invention can be formed according to the following formula:

[0025]

[0026] These components add up to a total of 1000 kg.

[0027] The aluminum sol is water-dispersed nano-scale alumina with a particle size of 20nm.

[0028] The photocatalytic medium is nano zinc oxide with a particle size of 15nm.

[0029] The pigment can be copper chrome black, which has excellent chemical corrosion resistance, outdoor weather resistance, heat stability, light resistance, and has no permeability and no migration.

[0030] The filler can be nano-sized microcrystalline powder silica, the whiskers have small particle size and strong dispersibility, which helps to achieve the purpose of uniform mixing in the coating.

[0031] The potassium titanate whiskers may be potassium octatitanate whiskers. This component can play a role in the molding and strength improvement of the overall coating.

specific Embodiment 2

[0032] The photocatalytic environment-friendly nano-ceramic coating of the present invention can be formed according to the following formula:

[0033]

[0034] These components add up to a total of 1000 kg.

[0035] The aluminum sol is water-dispersed nano-scale alumina with a particle size of 30nm.

[0036] The photocatalytic medium is a mixture of anatase and brookite nano-titanium dioxide in any proportion, and its particle size is 10nm.

[0037] The pigment can be titanium dioxide, which has strong hiding power, uniform and fine particles, easy dispersion and stable performance.

[0038] The filler can be alumina, which is a nano-scale powder with strong dispersion and easy to achieve uniform mixing in the coating. At the same time, because of its own nano-effect, it is beneficial to optimize the performance of the coating.

specific Embodiment 3

[0040] The photocatalytic environment-friendly nano-ceramic coating of the present invention can be formed according to the following formula:

[0041]

[0042]

[0043] These components add up to a total of 1000 kg.

[0044] The aluminum sol is water-dispersed nano-scale alumina with a particle size of 30nm.

[0045] The photocatalyst medium is anatase nano-titanium dioxide with a particle size of 10nm.

[0046]One of the pigments, optional cobalt blue, has excellent hiding power, color transparency and high tinting strength, thermal stability, light fastness, and high light reflectivity.

[0047] The filler may be potassium titanate whiskers, which are highly dispersible and help to achieve the purpose of homogenization and mixing in the coating. At the same time, because of the strength of the whiskers themselves, it is beneficial to strengthen the cohesion of the coating.

[0048] The potassium titanate whiskers may be potassium hexatitanate whiskers.

Abstract

The invention provides a photocatalytic environment friendly nano ceramic film coating and a preparation method thereof, belonging to the field of functional coating. The nano ceramic film coating is mainly prepared from nanoscale alumina sol, light touch media, pigment, filler, titanium potassium whisker, methyl trimethoxy silane, methyl-trimethoxysilane and the like, wherein, the light touch media is one or the complex system of nano titanium dioxide and nano zinc oxide. The preparation method is as follows: respectively weighing corresponding nanoscale alumina sol, light touch media, pigment, filler, methyl trimethoxy silane and methyl-trimethoxysilane, then mixing and dispersing at a high speed, and adding titanium potassium whisker to carry out low speed dispersion to obtain the photocatalytic environment friendly nano ceramic film coating. The coating prepared by the invention has the functions of self cleaning, sterilization, air purification and the like, and meanwhile, the coating has safety and no toxicity naturally, and is environment friendly nano ceramic film coating.

Description

technical field [0001] The invention belongs to the field of functional coatings, and relates to a nano-ceramic film coating with photocatalytic function and a preparation method thereof. Background technique [0002] At present, the problem of environmental pollution in our country is very prominent, especially the urban air pollution is very serious. Industrial coal burning releases a large amount of SO 2 , CO and other harmful gases; with the rapid development of the automobile industry, a large amount of nitrogen oxides and CO emitted by automobile exhaust have caused serious air pollution in large and medium-sized cities; many interior decoration materials and furniture will slowly release such as aldehydes, phenols, Small molecules such as alcohols are harmful organic substances, and central air conditioners also produce unpleasant odors and spread pathogenic microorganisms. Due to the aggravation of air pollution, it has become increasingly difficult to clean modern...
