Environmentally friendly anti-fog transparent thermal insulation nano glass coating and preparation method thereof

Abstract

The invention discloses an environmentally friendly anti-fog transparent thermal insulation nano glass coating, which is prepared from the following raw materials in parts by weight: 20 to 21 parts of nano tin antimony oxide, 0.2 to 0.3 part of dispersant SN-5040, 79 to 81 parts of waterborne polyurethane resin, 30 to 35 parts of deionized water, 40 to 50 parts of N,N'-Dimethyl formamide, 20 to 22 parts of 20% sulfuric acid solution, 20 to 22 parts of perfluorooctanoic acid, 3 to 4 parts of methyl methacrylate, 0.1 to 0.2 part of potassium persulfate, 3 to 3.5 parts of isocyanate, 0.7 to 0.9 part of hexadecyl phosphate, 0.1 to 0.2 part of diferrocene acetylene, and 0.7 to 0.8 part of nano sepiolite powder. According to the invention, the nano sepiolite powder is modified by using the hexadecyl phosphate and the diferrocene acetylene, so that the dispersity of the nano sepiolite powder is improved, harmful substances of the coating can be adsorbed to improve the environmental performance, and water molecules can be adsorbed so that the water molecules cannot condense, thus improving the anti-fog performance.

Description

technical field [0001] The invention relates to the technical field of glass coatings, in particular to an environmentally friendly anti-fog 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 bro...

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.
