Highly contamination resistant heat-insulating building coating

Abstract

The invention provides highly contamination resistant heat-insulating building coating, which comprises, by weight, from 30 to 40% of acrylate elastic emulsion, from 8 to 15% of modified organic silicon micro-emulsion, from 20 to 25% of rutile titanium dioxide, from 5 to 15% of infrared emitting powder and from 15 to 25% of filler. The highly contamination resistant heat-insulating building coating has a fine reflecting effect on solar radiation heat and is capable of emitting heat accumulating on the surface to the external space in a long wave form, so that surface temperature of a coated article is reduced, life and working environments can be improved, energy is saved and consumption is reduced. Furthermore, the coating has high contamination resistance, the reflecting effect on solar radiation cannot be reduced due to surface contamination, and accordingly the long-term stable heat-insulating effect can be maintained.

Description

technical field

[0001] The invention relates to the technical field of architectural coatings, in particular to a highly stain-resistant architectural heat-insulating coating. Background technique

[0002] External wall insulation materials have been widely used. For the external insulation of commonly used polystyrene boards and polystyrene particle insulation coatings, when ordinary coatings are used for finishing, the temperature of the protective layer can reach 80°C in summer, and the surface temperature can vary. Reaching 50°C, which often causes cracking of the anti-crack protection layer, which not only puts forward higher requirements for the flexibility of the anti-crack protection material, but also requires the elasticity, water resistance, temperature change resistance, and stain resistance of the finishing coating. , aging resistance and other requirements are more stringent.
