Anti-static transparent heat-insulating nano glass paint and preparation method thereof

Abstract

The invention discloses anti-static transparent heat-insulating nano glass paint. The anti-static transparent heat-insulating nano glass paint is prepared from the following raw materials in parts by weight: 20-21 parts of nano 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 imino oxadiazine diketone, 40-50 parts of N, N'-dimethyl formamide, 20-22 parts of a sulfuric acid solution with concentration being 20%, 20-22 parts of perfluoro caprylic acid, 3-4 parts of methyl methacrylate, 0.1-0.2 part of potassium peroxodisulfate, 3-3.5 parts of isocyanate, 1.2-1.3 parts of nano carbon sol and 0.7-0.9 part of sodium borohydride. According to the anti-static transparent heat-insulating nano glass paint, the nano carbon sol, sodium borohydride and imino oxadiazine diketon are used for mixing and modifying, so that the sodium borohydride and imino oxadiazine diketon are uniformly dispersed in the nano carbon sol, the nano carbon sol has hydrophilicity and lipophilicity and can be compatible with resin very well, the wear resistance, oxidization resistance and electrostatic resistance of the resin are improved, and the strength is not affected.

Description

technical field [0001] The invention relates to the technical field of glass coatings, in particular to an antistatic 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.
