Functional paint for outer wall

Abstract

The invention belongs to the field of paint, and relates to functional paint for an outer wall. The functional paint comprises a component A and a component B, and the component A is prepared from, by weight, 45-60 parts of base emulsion, 8-12 parts of glass beads, 7-10 parts of titanium dioxide, 7-12 parts of filler, 8-13 parts of water and 10-20 parts of auxiliary; the base emulsion is fluoroolefin and vinyl ester copolymer emulsion, and the filler is a mixture of one or more of kaolin, talcum powder and calcium carbonate and one or more of nano stannic oxide and nano antimony oxide; the component B includes water-based isocyanate and propylene glycol monomethyl ether acetate. The specific base emulsion is adopted in the paint, the match of all the ingredients in the paint is designed optimally, the obtained paint has heat insulation and reflection functions, is high in reflectivity, good in uniformity and anti-settling property, high weather and water resistance and has good adhesive force, and all good properties are stable.

Description

technical field

[0001] The invention belongs to the field of coatings and relates to a functional coating for exterior walls. Background technique

[0002] Exterior wall coatings can protect the exterior walls of buildings that have been exposed to wind, sun, and rain for years. They must have good enough water resistance, weather resistance, stain resistance and freeze-thaw resistance to ensure good performance. decorative effect and durability. Not only that, under the high radiation of the sun, the surface of the building is raised, and the heat is transferred to the interior of the building, which increases the working pressure of cooling equipment such as air conditioners, resulting in excessive energy consumption, which also requires Coatings can have the effect of heat insulation. In recent years, some reflective heat insulation materials and manufacturing methods have also appeared in the paint market, such as a Chinese invention patent with the patent number CN2014...
