Waterborne heat insulation waterproof coating material

Abstract

The invention discloses a water-based heat insulation and waterproof coating which is characterized in that the coating consists of materials with following weight percentage (two components), wherein, component A: 1-20 percent of soft water, 0.1-0.3 percent of hydroxyethyl cellulose, 0.1-0.2 percent of preservative, 0.1-0.4 percent of anti-mildew agent, 0.1-0.2 percent of organic amine, 0.1-0.3 percent of amine salt dispersant, 0.01-0.18 percent of defoamer, 1-4 percent of ethylene glycol, 80-93 percent of good alkali resistant and high elastic pure acrylic emulsion which can be mixed with cement, and 3-13 percent of ethylene - polyvinyl acetate emulsion; component B: 3- 20 percent of coarse whiting, 3-13 percent of saponite, 1-13 percent of titanium pigment, 1-6 percent of calcined kaolin, 5-16 percent of hollow sodium silicate particles with the average size approximating to 10 to 70 Mum, and 57-88 percent of the cement, wherein, A:B is equal to 1:0.8-1.3. The invention can be used for roofs and exterior walls, etc. and has the advantages of good heat insulation and waterproof effect, fine durability, easy coating, low cost and water-base environmental protection.

Description

technical field [0001] The invention relates to a water-based coating, in particular to a water-based and environmentally friendly heat-insulating and waterproof coating with good heat-insulating and waterproofing effects, good durability, easy coating, low cost and the like for roofs and exterior walls. Background technique [0002] At present, the coatings used for roofs and exterior walls are oil-based coatings or ordinary water-based architectural coatings, polymer cement-based coatings, etc. Oil-based coatings are not environmentally friendly, difficult to coat, high in cost, easy to age, and have poor heat insulation effects; while ordinary Water-based architectural coatings, polymer cement-based coatings, etc. have poor heat insulation and waterproof effects, and some have poor durability. Generally speaking, lack a kind of coating that is used for roof, the better coating of comprehensive performance of exterior wall etc. heat-insulating waterproof coating. The main...

Problems solved by technology

The main reason is that the organic solvent content is high; or the choice of film-forming substances and inorganic substances is not well matched; or the light and heat resistance of inorganic substances is poor, and the heat insulation and waterproof methods are single, and the effect is poor, etc.
