However, the addition of ceramic hollow microspheres and particle size distribution have an impact on the performance of the coating. The research results show that the increase in the addition of ceramic hollow microspheres will increase the reflectivity of the coating, but at the same time the viscosity of the coating will increase, which is not conducive to The workability of the coating increases the roughness and porosity of the coating film surface, easily absorbs impurities and moisture, and reduces the adhesion and stain resistance of the coating film
The coating thickness of this material needs to be thicker, and the surface is also relatively rough, so it has not been popularized and applied in a large area.
In addition, the existing thermal insulation coatings have poor environmental protection effect, therefore, how to develop environmentally friendly nano-reflective thermal insulation coatings has important practical significance

Abstract
The invention discloses an environmentally friendly nanometer reflective thermal insulation coating. The environmentally friendly nanometer reflective thermal insulation coating comprises, by weight,30-40 parts of a smell-removal emulsion, 30-40 parts of a pure acrylic emulsion, 15-25 parts of potassium titanate whisker slurry, 6-8 parts of ceramic microbeads, 2-5 parts of nanometer titanium dioxide, 0.2-0.6 parts of a dispersant, 5-9 parts of a filler, 0.3-0.7 parts of an antifoaming agent, 10-14 parts of alumina powder and 0.4-0.8 parts of an antibacterial agent. The environmentally friendly nanometer reflective thermal insulation coating has effects of environmental protection, mildew resistance and bacterial inhibition, outstanding reflective and thermal insulation properties, film strength and elongation, has strong function durability, short film drying time and good hardness, and has good elongation performances and heat resistance. The coating film can prevent mildew for a long time. The antibacterial formaldehyde-removing coating is non-toxic and environmentally friendly and can high effectively purify formaldehyde.
Description
technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an environment-friendly nano-reflective heat-insulating coating. Background technique [0002] Reflective heat insulation coatings first appeared in the United States in the 1940s. Air with low thermal conductivity was introduced between multi-layer aluminum films to make composite materials. new era. At the beginning, the research on reflective and heat-insulating coatings was mainly based on vacuum ceramic microbeads. Rely on the composition of vacuum ceramic microbeads with extremely small particle size and their compatible resin. This kind of ceramic heat-insulating coating is applied to the interior and exterior walls of buildings, which can play a role in heat insulation. In summer, the indoor temperature can be lowered, and in winter, the indoor temperature can be increased. However, the addition of ceramic hollow microspheres and the particle size distribu...
