preparation example Construction

[0034] In the present invention, a kind of preparation method of high leveling glass thermal insulation paint, its steps are:

[0035] 1) Add water and polyvinyl alcohol to the modified colloidal rheological thickener formula in the reaction pot according to the weight ratio, and then gradually raise the temperature to 95°C at a stirring speed of 110-180 rpm;

[0036] 2) After the polyvinyl alcohol is completely melted, cool down to 60°C, then slowly add acrylamide, sodium bisulfite and n-methacrylamide in sequence according to the mass ratio, then raise the temperature and keep it at 110-180 rpm Continue to stir;

[0037] 3) When the temperature rises to 70°C, slowly add the persulfate initiator solution according to the ratio, and react for two hours to form a modified colloidal rheological thickener;

[0038] 4) Weigh the raw materials according to the weight ratio of the above high leveling glass heat insulation coating formula, then add the polymer emulsion and water int...

Embodiment 1

[0042] 1) Add 70 kilograms of water and 7.5 kilograms of polyvinyl alcohol into the reaction pot according to the mass ratio, and then gradually raise the temperature to 95°C at a stirring speed of 110-180 rpm;

[0043] 2) After the polyvinyl alcohol is completely melted, cool down to 60°C, then slowly add 6 kg of acrylamide, 0.2 kg of sodium bisulfite and 0.5 kg of n-methacrylamide according to the mass ratio, then raise the temperature and keep it at 110- Continue stirring under the condition of 180 rpm;

[0044] 3) When the temperature rises to 70°C, slowly add 2 kg of persulfate initiator solution according to the proportion, and react for two hours to form a modified colloidal rheological thickener;

[0045] 4) Weigh the raw materials according to the above mass ratios, then add 50 kg of polyacrylate emulsion and 25 kg of water into the stirring container, and slowly add nano indium tin oxide ( 20 kg of ITO) slurry and stirred for 20 to 50 minutes at room temperature of ...

Abstract

The invention discloses a thermal insulating glass coating with high leveling property and a preparation method thereof. The thermal insulating glass coating with high leveling property comprises the following formulations: 20-75 of polymer emulsion, 0.05-10 of fluorine surfactant, 5-30 of functionality nano-filler, 0.2-0.5 of mould inhibitor, 0.1-1 of compound antifoaming agent, 0.6-2 of anti-freezing agent, 1-20 of modified colloidal rheology thickening agent and 10-50 of water. In the invention, the product is used for various transparent thermal insulating coatings with transparent glass surfaces and infrared light reflection. The coating is spread on the glass surfaces radically without influencing the transparent property of the glass and can reflect the infrared light irradiating to the glass surface so as to prevent the infrared light from projecting on the glass surface and penetrating through the glass surface to rise the temperature, thereby achieving achieve functions of transparency and thermal insulation. Compared with the prior art, the technical product of the invention has the advantages of high leveling property, excellent wettability, low production cost and thelike.

Description

technical field [0001] The invention relates to a nano-functional coating, in particular to a high-leveling nano-glass heat-insulating coating and a preparation method thereof. Background technique [0002] For half a century, with the massive exploitation of non-renewable resources such as petroleum, coal mines, and natural gas in the world, especially after the energy crisis in 2004, people have paid more attention to energy conservation and consumption reduction. Building energy conservation is not only an important issue faced by countries all over the world, but also a basic national policy of our country. At the World Climate Conference held in Copenhagen in December 2009, facing the serious threat of global warming, the governments and peoples of all countries placed the responsibility of saving energy, reducing consumption and reducing carbon emissions to save the earth and build a beautiful homeland. Low-carbon buildings based on low energy consumption, low polluti...
