Problems solved by technology

The poor heat insulation effect of ordinary glass is one of the main reasons for the energy loss or energy consumption increase of buildings. The hot summer makes the air conditioning load significantly increase.
[0003] At present, the metal-coated heat-reflective glass and various heat-reflective films used in the market, although they can block part of the sunlight to achieve the purpose of heat insulation and cooling, but there are some problems in the application of these products. Metal-coated heat reflection Glass has a good heat insulation effect, but the transmittance of visible light is very low, and its application on building glass will affect indoor lighting; the high reflection of metal-coated heat-reflective glass on visible light will cause light pollution, and its application in buildings is currently prohibited
Although the heat reflective film glass has a high visible light transmittance, but the heat insulation effect is poor
In addition, the above two heat insulation methods require expensive equipment, a large amount of energy consumption, and high cost, which is not conducive to large-scale promotion in the market

Abstract

The invention discloses a preparation method of heat-resisting transparent heat-insulation UV-curing coating, belonging to the technical field of photocureable coating. The preparation method comprises steps of respectively putting the mixed solution of dispersing agent and diluent and different nano-powders into a beaker, adjusting pH to 9.0-10.0, carrying out ultrasonic dispersion after stirred on a magnetic stirrer, and stopping ultrasonic agitation to obtain nano-powder slurry; according to different nano-powder mass ratios, evenly mixing the slurry; putting hydroxy silicone oil, crylic acid and 4-methoxyphenol into the breaker at the temperature of 110 DEG C to react for 5 hours, and preparing UV curing resin; adding nano slurry into the UV curing resin, defoamer, thickening agent and film-forming auxiliary agent, adjusting pH to 9.0-10.0 to obtain heat-resisting transparent heat-insulation UV-curing coating. The invention has simple preparation and construction technology, effectively lowers production cost and is favorable for popularizing to the market. The prepared coat has higher visible light transmittance, infra-red reflectivity, transparent coat, strong hardness, favorable adhesive force, resistance to soiling, ultraviolet ray aging resistance and high temperature resistance.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature-resistant transparent heat-insulating ultraviolet light curing coating used on building glass and fire trucks, and belongs to the technical field of light curing coatings. Background technique [0002] With the rapid development of social economy, energy saving has become the focus of the whole society. Because ordinary glass is not selective to sunlight, when sunlight passes through the glass window, the heat generated by sunlight radiation is also transmitted into the room at the same time, increasing the indoor temperature. The poor heat insulation effect of ordinary glass is one of the main reasons for the energy loss or energy consumption increase of buildings. The hot summer makes the air conditioning load significantly increase. [0003] At present, the metal-coated heat-reflective glass and various heat-reflective films used in the market, although they can block part of the s...
