Infrared isolation pulp and infrared isolation coating for toughened glass thereof

Abstract

The invention relates to a coating, in particular to an infrared separating slurry which is prepared from the following raw materials by weight percentages: 20 to 25 weight percentages of nanometer ATO powder or nanometer ITO powder, 20 to 30 weight percentages of alcohol, 15 to 25 weight percentages of glycol, 20 to 30 weight percentages of isopropanol, 15 to 25 weight percentages of water and 2 to 5 weight percentages of a dispersing agent SDBS. The nanometer silicon dioxide sol prepared by the sol-gel method of the infrared separating coating prepared from the slurry and used for tempered glass is different from the traditional organic resin, the coated film layer has high hardness, and after being processed at a high temperature with the glass, the coated film layer has the hardness of 5 H to 6H, aging resistance and twenty-year durability. The coating has very thin film layer, guarantees the transparency and high penetration rate of visual light of the glass, is convenient for transportation and the construction are convenient, greatly reducesthe cost.

Description

technical field [0001] The invention relates to the field of nano functional coatings, in particular to slurry, and also to infrared blocking coatings. Background technique [0002] Under the situation of vigorously promoting energy saving and emission reduction, the energy saving status of domestic buildings has been paid attention to, and the market demand for energy saving glass is also expanding day by day. The new national building energy efficiency standard stipulates that the energy efficiency of new buildings must reach 50%. At present, my country's building energy consumption accounts for 40% of the total energy consumption, and the energy lost through doors and windows accounts for 46% of building energy consumption. Therefore, building energy conservation must first be grasped from doors and windows. [0003] Building energy consumption is mainly lighting and air conditioning. Increase the transmittance of visible light as much as possible, reduce the time of tu...

Problems solved by technology

Because the glue will age, the service life is short, and its surface hardness is only 1H ~ 2H, which is easy to be damaged. The cost of the film with the same effect is twice that of heat-insulating glass, and it cannot be applied on concave-convex glass.

[0009] At present, the thermal insulation coating used on glass developed by people is to add infrared blocking material to the transparent organic polymer coating material. The disadvantage is that it is not wear-resistant and easy to age compared with glass.
