Abstract

The invention discloses a solar heat reflective thermal insulation coating and a preparation method thereof. The coating comprises the following components: an adhesive, hollow glass beads, a wetting dispersant, a defoaming agent, an antifreeze agent, a coalescing agent, a thickening agent, a pH regulator, a pigment filler and water. The modified xanthan gum treated by the alternating copolymer of 1-octadecene and maleic anhydride is adopted to modify the silicon dioxide aerogel, so that the compatibility between the silicon dioxide aerogel and the acrylic emulsion is improved, the heat-insulating property and the stain resistance of the coating are improved, and the coating can be used as a reflective heat-insulating coating for building exterior walls, and can be used as a reflective heat-insulating coating for building exterior walls. And energy conservation of buildings can be realized.

Description

technical field [0001] The invention relates to the technical field of building energy-saving functional coatings, in particular to a solar heat-reflecting heat-insulating coating and a preparation method thereof. Background technique [0002] As an inexhaustible source of energy in nature, solar heat plays a vital role in our lives. In order to solve the problem of energy shortage, people are constantly designing and developing more effective ways and means to use solar energy. And achieved a series of progressive results. [0003] However, too much solar heat radiation can also cause a series of problems. One is that too much heat builds up on the ground, especially in the tropics in summer. There is continuous interaction between human beings and the surrounding environment. Thermal radiation has a great impact on human health and comfort. Second, excessive solar thermal radiation can also cause many adverse photochemical reactions, such as plastic aging, degradation, h...
