Abstract
The invention relates to a self-cleaning type outer wall coating and a preparation method thereof, and belongs to the technical field of coatings. The self-cleaning type outer wall coating is prepared from the following raw materials in parts by weight: 30 to 40 parts of organic silicon latex, 20 to 30 parts of organic fluorine latex, 20 to 30 parts of silicon-scrylic latex, 0.5 to 1.0 part of a defoaming agent, 0.5 to 1 part of a sodium acrylate dispersing agent, 3 to 5 parts of a sodium hexametaphosphate dispersing agent, 1 to 2 parts of isopropyl alcohol, 25 to 30 parts of titanium dioxide, 10 to 15 parts of pigment and 50 to 100 parts of water. Due to the use of the organic silicon latex and the organic fluorine latex which are relatively low in polarity in the coating formula and the adding of a little of the silicon-scrylic latex, the adsorption capacity of an outer wall coating layer to pollutants and dust is effectively reduced, the pollutant resistance of the coating layer is enhanced, and relatively high self-cleaning property is realized; the long-term aesthetic property of an outer wall is improved, and the service life of the coating is prolonged.
Description
Technical field
The present invention relates to a kind of coating and preparation method thereof, it is more particularly related to a kind of self-clean type exterior wall is applied
Material and preparation method thereof, belongs to technical field of coatings.
Background technology
Polyacrylic acid latex is widely used at present as the primary raw material of pure polyacrylicresin outer wall paint, due to its excellent weatherability
Property, preferably appearance of coat, can preferably compound processing characteristics, acrylic compounds exterior coating prepare in have highly important
Using.But because general commercially available acrylic based emulsion has stronger polarity, there is stronger adsorption capacity to dust, greasy dirt etc., by
Exterior coating coating prepared by it is caused the pollution of coating due to the absorption to above-mentioned substance and is stained, and has been had a strong impact on outer
The spatter property of wall coating and attractive in appearance.Simultaneously as need Jing often to clean metope, considerably increase outer wall coating service life and
Cost.
The content of the invention
Present invention seek to address that the problem that exterior coating easily pollutes in prior art, there is provided a kind of self-clean type exterior wall is applied
Material, the coating has self-cleaning function, it is ensured that the cleaning of exterior wall surface.
In order to realize foregoing invention purpose, its specific technical scheme is as follows：
A kind of self-clean type exterior coating, it is characterised in that：Including following raw materials by weight：
Organosilicon latex 30-40 parts
Organic fluoride latex 20-30 parts
The latex 20-30 parts of silicon-the third
Defoamer 0.5-1.0 parts
PAA dispersant 0.5-1 parts
Calgon dispersant 3-5 parts
Isopropanol 1-2 parts
Titanium dioxide 25-30 parts
Pigment 10-15 parts
Water 50-100 parts.
A kind of preparation method of self-clean type exterior coating, it is characterised in that：Comprise the following steps that：
A, in a 100L rustless steel container accurately weigh isopropanol, titanium dioxide, pigment, water and PAA by recipe requirements
Dispersant, calgon dispersant, isopropanol, preliminary stirring mixing；After above-mentioned each component dispersed with stirring is well mixed, transfer
To high speed disperser, defoamer is added；Disperse 0.5-1.0h at a high speed in high speed disperser；
B, it is subsequently adding organosilicon latex, Organic fluoride latex, the latex of silicon-the third and disperses 2-3h at a high speed in high speed disperser；Again will
It is transferred on double roller or three-roller through the scattered material of high speed and further mill dispersion 3-5 time；
C, cooling, discharging, filter, and are packaged to be product.
The Advantageous Effects that the present invention brings：
The present invention is by the relatively low organosilicon latex of polarity, Organic fluoride latex used in formulation for coating material, while adding a small amount of
The latex of silicon third, effectively reduces outer wall coating to pollutant, the adsorption capacity of dust, improves the antipollution thing of paint coatings
Property, with stronger self-cleaning.The long-term aesthetic property of exterior wall is not only increased, while improve the service life of coating.
