Antibacterial transparent heat-insulation nanometer glass paint and preparing method thereof

Abstract

The invention discloses an antibacterial transparent heat-insulation nanometer glass paint .The antibacterial transparent heat-insulation nanometer glass paint is prepared from, by weight, 20-21 parts of nanometer tin antimony oxide, 0.2-0.3 part of a dispersing agent SN-5040, 79-81 parts of waterborne polyurethane resin, 30-35 parts of deionized water, 0.6-0.8 part of sodium fluorosilicate, 40-50 parts of N,N'-dimethylformamide, 20-22 parts of a 20% sulfuric acid solution, 20-22 parts of perfluorocaprylic acid, 3-4 parts of methyl methacrylate, 0.1-0.2 part of potassium persulfate, 3-3.5 parts of isocyanate, 1.2-1.3 parts of chitin whiskers and 0.2-0.3 part of hydrogenated castor oil .According to the antibacterial transparent heat-insulation nanometer glass paint, chitin whiskers, hydrogenated castor oil and sodium fluorosilicate are used for blending modification, the water resistance and lipophilicity of chitin whiskers are improved, and the caking property of chitin whiskers and resin is improved so that the strength and adhesive force of a coating can be better increased, and the antibacterial performance of the paint can be improved .

Description

technical field [0001] The invention relates to the technical field of glass coatings, in particular to an antibacterial transparent heat-insulating nano glass coating and a preparation method thereof. Background technique [0002] As society pays more and more attention to energy saving and environmental protection requirements, insulating glass that can be used in different places has become a common demand of people, but the existing insulating glass has the disadvantages of imperfect performance, complicated process or high cost. Nano antimony tin oxide (ATO) has good visible light transmittance and infrared barrier, and is an ideal heat insulation material. The method of adding nano-tin antimony oxide into the paint to make a transparent heat-insulating paint can effectively solve the heat-insulating problem of glass. Compared with similar products, it has the advantages of simple process and low cost, and has extremely high application value and broad application value...

Problems solved by technology

[0003] However, the coating film has certain water absorption and water permeability. After absorbing water, it is easy to cause wrinkles and fall off. Nano-indium tin oxide will be denatured under the action of long-term water, which will affect the heat insulation effect. Water resistance needs to be improved.

[0004] In addition, there are still some problems to be solved in the glass coating film, such as heat resistance, wear resistance, antistatic property, toughness, antibacterial property, acid and alkali resistance, transparency, scratch resistance, environmental performance, radiation resistance, anti-discoloration , Flame retardancy, UV resistance and other properties will have different requirements in different occasions. The current coatings still cannot meet the needs of all environments, and the performance needs to be further improved to meet the needs of production.
