Problems solved by technology

However, due to the low hardness of the paint film on the glass surface of the existing products, it is only suitable for the inner side of the insulating glass, and if it is used for a single piece of glass, the paint film is easily damaged by external forces during later use, such as When cleaning the glass, wipe it with a rough object, which will cause scratches and scratches on the paint film
In the case that single-pane glass is still widely used in buildings in our country, the problem of low hardness of the paint film of existing products has led to the failure of large-scale promotion and application of products

Embodiment 1

[0016] Add 60 parts of inorganic ceramic resin (A-10-9, Shanghai Ruiju Polymer Materials Co., Ltd.) and 40 parts of ATO slurry (China Shipbuilding Industry Corporation, solid content 21-22%) to the paint mixing tank in turn. , stir at 500rpm for 15min (min); slowly adjust the speed to 1500rpm (rev / min), gradually add 0.3 part of defoamer, continue stirring for 15min; add 0.15 part of foam inhibitor and 0.2 part of substrate wetting agent, reduce The rotating speed was adjusted to 800 rpm and stirred for 15 min; 6.5 parts of co-solvent diethylene glycol butyl ether was added, the rotation speed was adjusted to 600 rpm, and the stirring was continued for 20 min; the rotating speed was reduced to 500 rpm and defoaming was performed for 20 min. If there is still a lot of foam, it can be left to stand for about 24 hours to defoaming, then filtered and packaged.

Embodiment 2

[0018] Add 60 parts of inorganic ceramic resin (K7000, American Huajinsi Co., Ltd.) and 40 parts of ATO slurry into the paint mixing tank in turn, and stir at 600rpm for 15min; slowly adjust the rotation speed to 1000rpm, and gradually add 0.2 part of the Foaming agent, continue stirring for 15min; add 0.2 part of foam inhibitor and 0.3 part of substrate wetting agent, reduce the speed to 800rpm, add 0.3 part of leveling agent, continue stirring for 20min; reduce the speed to 500rpm, defoaming for 10min . If there is still a lot of foam, it can be left for about 12 hours to defoaming, then filtered and packaged.

Embodiment 3

[0020] Add 70 parts of inorganic ceramic resin (KZ-707, Philadelphia Chemical Company, USA) and 30 parts of ATO slurry (China Shipbuilding Industry Corporation, solid content 21-22%) in turn to the paint mixing tank, and stir at 600 rpm. 15min; slowly adjust the speed to 1000rpm, gradually add 0.3 part of defoamer, and continue stirring for 15min; add 0.2 part of foam inhibitor and 0.2 part of substrate wetting agent, reduce the speed to 800rpm, and stir for 15min; add 7.5 parts of auxiliary Solvent ethylene glycol butyl ether, adjust the rotation speed to 600rpm, continue stirring for 20min; lower the speed to 500rpm, defoaming for 20min. If there is still a lot of foam, it can be left for about 12 hours to defoaming, then filtered and packaged.

Abstract

The invention provides high-hardness one-component transparent heat-insulation paint for glass. The paint contains the following ingredients of: by weight, 50-90 parts of high-hardness polymer resin, 10-50 parts of a nanometer heat-insulation slurry, 0-10 parts of a cosolvent, 0-0.5 part of an antifoaming agent, 0-0.5 part of a foam inhibitor, 0-0.5 part of a base-material wetting agent and 0-0.5 part of a leveling agent. The high-hardness one-component transparent heat-insulation paint for glass in the invention has more than 6H of paint film hardness, can effectively avoid the destroy of outside force to the paint film when used on a single piece of glass, has over 50% of infrared ray blocking rate and more than 70% of visible light transmittance, can block most daylight radiant heat, but has little influence on lighting. The paint provided by the invention has advantages of simple construction process and low use cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness single-component transparent heat-insulating coating for glass. Background technique [0002] With the rapid development of science and technology and social production, energy and environment have become two major issues that the whole society is paying more and more attention to, thus putting forward higher requirements for energy conservation and environmental protection. Glass curtain walls and windows, which are widely used in large-area windows and transparent ceilings of buildings, automobiles, display freezers and other occasions, need to effectively isolate heat radiation, and have higher requirements on the permeability of visible light. Since ordinary glass is not selective in the transmission of sunlight, while sufficient visible light is transmitted, a large amount of heat in the infrared region of the solar spectrum will also be transmitted. In ord...
