Abstract

The invention discloses a flame retardant, transparent and heat insulating nano glass coating .The flame retardant, transparent and heat insulating nano glass coating is prepared from, by weight, 20-21 parts of nano antimony tin 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, 40-50 parts of N, N'-dimethylformamide, 20-22 parts of a sulfuric acid solution with the concentration being 20%, 20-22 parts of perfluoro caprylic acid, 3-4 parts of methyl methacrylate, 0.1-0.2 part of potassium persulfate, 3-3.5 parts of isocyanate, 0.4-0.5 part of sulfosalicylic acid, 0.3-0.4 part of edetic acid, 0.4-0.5 part of nano copper and 1.2-1.4 parts of a hydroxyl aluminum oxalate solution .According to the flame retardant, transparent and heat insulating nano glass coating, the sulfosalicylic acid and the edetic acid are utilized to modify the nano copper and the hydroxyl aluminum oxalate solution, the nano copper and hydroxyl aluminum oxalate are evenly dispersed in the coating, flame retardance and wear resistance are improved, and the shading property for ultraviolet light of the coating is further improved .

Description

technical field [0001] The invention relates to the technical field of glass coatings, in particular to a flame-retardant 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 valu...

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.
