Reflection heat insulating coating for building

Abstract

The invention discloses a reflection heat insulating coating for a building. The reflection heat insulating coating comprises the following components in parts by weight: 9.5 to 23 parts of water, 0.44 to 1.08 parts of thickener, 0.45 to 0.55 part of dispersing agent, 0.1 to 0.2 part of wetting agent, 0.4 to 0.8 part of defoaming agent, 0.05 to 0.25 part of multifunctional auxiliary agent, 0.05 to 0.15 part of preservative, 0.05 to 0.25 part of mildew preventive, 15 to 25 parts of titanium dioxide, 0 to 22.5 parts of nano heat insulating powder slurry, 2 to 6.5 parts of filling, 1 to 2 parts of anti-freezing agent, 1.25 to 2 parts of coalescing agent, 0.01 to 0.02 part of emulsifying agent, 25 to 40 parts of emulsion, 2.5 to 5 parts of hydrophobing agent, 0.05 to 0.15 part of pH value adjustment agent and 0.02 to 0.07 part of tributyl phosphate. After the coating is formed into a film, the surface of the coating is high in hydrophobicity; the coating has hydrophobic, water-proof and self-cleaning functions; and the heat insulating performance of the coating film can be improved.

Description

technical field [0001] The invention relates to a reflective and heat-insulating coating for buildings, which belongs to the technical field of building materials. Background technique [0002] In recent years, with the country's emphasis on building energy conservation, the external wall insulation market has developed rapidly. Although various forms of external wall insulation systems such as rock wool board, polystyrene board, extruded board and thermal insulation particle mortar have played a certain role in energy saving and emission reduction in the construction field, some shortcomings have gradually been exposed, such as The construction method is complex, the construction period is long, the cost is high, and the quality control is difficult. [0003] In view of this, great progress has been made recently in the research of reflective and heat-insulating coatings for buildings. Different from traditional external insulation of external walls, reflective thermal in...

AI Technical Summary

Problems solved by technology

However, this kind of reflective heat-insulating coating has the following unavoidable problems: (1) Due to the shielding effect of other fillers, the reflective effect of functional fillers is affected; (2) Because the particle size of functional fillers is generally large, in some (3) Due to the brittle and brittle characteristics of functional fillers, they cannot be produced completely according to the traditional architectural coating process, so most manufacturers currently use the rolling altar method for production , and this production process has low efficiency, prolonged production time, difficult equipment cleaning, and large investment in equipment

[0005] Therefore, the existing reflective and heat-insulating coatings for buildings restrict their development and application in the field of building energy conservation.
