Abstract

The invention provides thin coating type water-based heat insulation and thermal isolation paint and a preparation method thereof. The thin coating type water-based heat insulation and thermal isolation paint is prepared from the following ingredients in parts by mass: 5 to 20 parts of hydrophobic modified expanded vermiculite, 5 to 20 parts of hollow glass micro beads, 20 to 45 parts of emulsion, 5 to 15 parts of filling materials, 0.1 to 1 part of wetting agents, 0.1 to 1.0 part of dispersing agents, 0.8 to 1.5 parts of thickening agents, 0.1 to 0.5 part of pH regulators, 0.01 to 0.2 part of antifoaming agents, 0.01 to 0.2 part of sterilizing agents and 10 to 30 parts of water. The thin coating type water-based heat insulation and thermal isolation paint provided by the invention has the advantages that hydrophobic modified expanded vermiculite and the hollow glass micro beads are used and are uniformly dispersed into the elastic acrylic ester type emulsion with excellent heat-resistant weather-resistant anti-corrosion alkali-resistant and water-proof performance to form the paint; good heat insulation and thermal isolation performance is realized; the coating thickness can be reduced to 850 to 1500 micrometers.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to the technical field of building wall coatings, in particular to a thin-coated water-based thermal insulation coating and a preparation method thereof. Background technique [0002] The energy problem is a major challenge that our country needs to deal with for a long time. Building energy consumption occupies a pivotal position in the total energy consumption of human society, and its proportion is usually between 30% and 40%. The largest energy consumption points of buildings are air conditioners and Heating, whose energy consumption accounts for 55% of the total building energy consumption. As far as my country is concerned, according to the latest data released by the Ministry of Construction, 80% of the newly added 2 billion square meters of construction area in my country each year are high-energy buildings, and the proportion of high-energy buildings in the existing 43 bil...
