Problems solved by technology

However, the currently used polymer hollow microspheres and heat-insulating and reflective functional powders are used independently or in combination; the polymer hollow microspheres used to prepare polymer resins are mainly polymer resins without functional fillers, so the application of ordinary polymer hollow microspheres The heat insulation and reflection effect of the paint on the ball is not ideal, and needs to be further improved

Abstract

The invention discloses thermal insulation reflection coating polymer composite packing which consists of two parts, namely, functional packing and a polymer, wherein the functional packing accounts for 0-50% in weight ratio; the polymer accounts for 50-100% in weight ratio; the functional packing is packing with reflection and radiation functions for infrared rays, and is a composite of one or more of titanium dioxide, zirconia, aluminum oxide, hollow glass beads, hollow ceramic and silicon carbide; the polymer takes the shape of a microball; the microball can be a solid microball or a hollow microball. The packing can be applied to building coatings, paper surface coatings, leather treatment agents and the like, is particularly applicable to outer wall thermal insulating reflection coatings, and has the advantages of environment-friendliness, low cost, convenience for use, good effect and the like as no other polymer adhesives are used.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a heat-insulating reflective coating polymer composite filler. Background technique: [0002] At present, improving the thermal insulation performance of buildings is an important way to save energy and improve the function of buildings. Reflective coatings for building heat insulation can reduce the absorption of solar radiation energy by the surface of buildings by effectively reflecting solar heat radiation. Therefore, heat-insulating reflective coatings are getting more and more attention from society. At present, the widely researched heat-insulating and reflective coatings mainly use inorganic nano-powders, such as titanium dioxide and glass hollow microspheres, as raw materials to perform heat-insulating and reflecting sunlight. The use effect of colored paint or dark paint needs to be further improved. Studies have shown that the thermal effect mainly caused by inf...
