Abstract

The invention discloses water-based color-changing heat-insulating glass paint and a preparation method thereof, and belongs to the technical field of coatings. The water-based color-changing heat-insulating glass paint is composed of a component A and a component B, wherein the component A is prepared from the following components in parts by mass: 65-80 parts of acrylic hydroxy resin, 3-5 partsof a solvent, 10-20 parts of distilled water, 0.5-1.0 part of a dispersant, 5-10 parts of heat-insulating nanoparticles, 3-5 parts of discoloration fiber, 0.3-0.6 part of a defoaming agent and 0.5-1.0part of a thickening agent; and the component B is prepared from the following components in parts by mass: 10-12 parts of an isocyanate curing agent and 8-10 parts of a high boiling point solvent. The glass paint has a heat-insulating effect, no dew condensation and frost occurs on the glass surface in alternating cold and heat and cold winter, and the glass paint further has a color changing function, under the irradiation of sunlight, ultraviolet rays and infrared rays, color can be changed so that a shading and beauty illusion effect is achieved to meet the attractive pursuit of people.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based color-changing heat-insulating glass paint and a preparation method thereof. Background technique [0002] Reflective heat insulation coating has good heat insulation effect, can reflect about 80% of solar radiation heat, and the construction of heat insulation coating is simple, only simple spraying is required; the cost is low, only 1 / 2 of inorganic heat insulation materials. Therefore, using thermal insulation coatings to reduce building energy consumption is a very feasible means of energy conservation and emission reduction, especially for the regions south of the Yangtze River in my country. [0003] The development speed of heat-insulating coatings is very fast, and the environmental protection water-based heat-insulating coatings that are used more at present, such as water-based reflective heat-insulating coatings (CN 1986664 A); have gradually developed w...
