example 1

[0018] The nanoscale powder of lanthanum hexaboride, a rare earth material, was forced to stir in pure water for 10 minutes, then ultrasonically dispersed for 30 minutes, and then added to a sand mill to grind and disperse for 24 hours to obtain nano-lanthanum hexaboride pure water dispersion. The particle size of the nanometer lanthanum hexaboride in the liquid is about 30 nanometers. Then add an appropriate amount of the dispersion liquid into the water-based acrylic resin, complex alcohol, and additives, and then compulsively stir and disperse to obtain the nano-rare earth heat-insulating transparent coating. And the weight ratio of dispersion liquid, water-based acrylic resin, complex alcohol and additives is as follows:

Abstract

The invention discloses a nano-rare earth heat-insulated transparent coating and a preparation method thereof. The preparation method comprises the following steps of: firstly, forcibly stirring a nano-rare earth material lanthanum hexaboride in pure water for 10 minutes, then performing ultrasonic dispersion on the mixture for 30 minutes, and adding the mixture into a sand grind to perform grinding and dispersion for 24 hours to obtain a pure water dispersion liquid of the nano-lanthanum hexaboride; secondly, adding an appropriate amount of the dispersion liquid into a water-based acrylic resin or water-based polyurethane resin, composite alcohol and an additive; and finally, forcibly stirring and dispersing the mixture for 30 minutes to obtain the nano-rare earth heat-insulated transparent coating. The nano-rare earth heat-insulated transparent coating can reduce the indoor temperature by 7 to 10 DEG C when used on glass, and the light transmittance of the nano-rare earth heat-insulated transparent coating is up to over 80 percent.

Description

technical field [0001] The invention relates to a nano rare earth heat-insulating transparent coating and a preparation method thereof, belonging to the field of new materials. The invention can be used on the surface of transparent materials such as building glass curtain wall, window glass, vehicle glass and the like, and has excellent heat insulation performance. Background technique [0002] In recent years, my country's economy has developed rapidly, and resource and energy issues have become increasingly prominent, so energy conservation and environmental protection are particularly important at present. Especially in the urban renewal in recent years, it has highlighted the problems of high energy consumption, high pollution, and high carbon emissions caused by a large number of existing buildings due to defects in maintenance structures. According to statistics, 30% to 50% of building energy consumption is consumed on maintenance structures, and the main way of diss...
