Abstract

The present invention discloses a thermal-insulation building thin layer aqueous coating material and a preparation method thereof, wherein the coating material comprises the following raw materials by weight: 16-30 parts of an acrylic emulsion, 10-20 parts of a filler, 20-26 parts of barium residue, 1-5 parts of kaolin, 5-18 parts of titanium dioxide powder, 1-4 parts of dodecanol lipoid, 0.1-0.2 part of 2-methyl-4-isothiazolin-4-one, 0.1-0.4 part of 2-n-octyl-4-isothiazolin-3-one, 0.1-0.4 part of BASF A10, 0.1-0.5 part of sodium polyacrylate, 8-15 parts of sodium tripolyphosphate, and 10-20 parts of water. The preparation method comprises: taking samples according to the weight part ratio, taking the filler, the barium residue, the kaolin, the titanium dioxide powder and the water, mixing, adding the sodium tripolyphosphate, stirring to achieve a uniform state, adding the acrylic emulsion and the dodecanol lipoid, stirring to achieve a uniform state, adding the remaining raw materials, and carrying out ball milling to obtain the finished product. According to the present invention, characteristics of good performance, low cost, energy saving, and emission reducing can be achieved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a heat-insulating building thin-layer water-based paint, and also relates to a preparation method of the heat-insulating building thin-layer water-based paint. Background technique [0002] The traditional thermal insulation of buildings usually adopts externally hung organic or inorganic insulation boards, but the floor space is large, the construction period is long and the construction process is complicated, and there are also safety hazards such as flammability, easy delamination, easy falling off, and easy leakage. . [0003] With the development of coating technology, building thermal insulation coatings have been used in the field of building energy conservation due to their advantages of economy, environmental protection, convenient use, and obvious energy-saving effects. a technological trend. Coatings are mainly composed of aggregates with thermal insula...
