Two-component heat-insulated waterproof paint

Abstract

The invention discloses two-component heat-insulated waterproof paint which comprises a slurry A component and a powder B component; the A component comprises the following ingredients by weight: 1-20% of soft water, 0.1-0.25% of organic amine, 80-95% of pure acrylic emulsion, and 2-14% of ethylene-polyvinyl acetate emulsion; the B component comprises the following ingredients by weight: 2-25% of heavy calcium, 2-14% of talcum powder, 1-14% of titanium dioxide, 1-7% of calcined kaolin, 4-17% of borsal hollow microspheres with an average particle size of about 10-80 microns, and 50-90% of cement; the mass ratio of the A component to the B component is 1:0.7-1.4. The invention is applicable to roofs, exterior walls, and the like, has good heat insulation and waterproof effect, good endurance, easy coating, no toxicity, no smell, no harm to human body, and no environment pollution.

Description

technical field [0001] The invention relates to a coating, in particular to a two-component heat-insulating and waterproof coating. Background technique [0002] At present, the coatings used for roofs and exterior walls are oil-based or ordinary water-based coatings, polymer cement-based coatings, etc. Oil-based coatings are not environmentally friendly, difficult to paint, high in cost, easy to age, and have poor heat insulation effects; Water-based coatings, polymer cement-based coatings, etc. have poor durability and cannot achieve the effect of heat insulation. Single-component polyurethane is used both indoors and outdoors. It is very thick after brushing, about 3.0mm, but this kind of waterproof coating has a strong smell, which is difficult for ordinary people to accept. The polyurethane is gel-like and very thick. It needs a scraper during construction, which is very laborious and complicated. , and the heat insulation effect is not good. Contents of the inventio...
