Abstract
The invention provides an indoor thermal insulation coating. The coating is prepared from the following raw materials in parts by weight: acrylic resin, aggregate particles, superfine calcium carbonate, a thickening agent, a coalescing agent, carbamate, a defoaming agent, a PH regulator, water, modified cellulose and a carbon forming agent. The preparation method of the acrylic resin comprises the following steps: 1, stirring and mixing 100-200 parts by weight of methacrylate, 300-320 parts by weight of a polyvinyl compound and 0.5-1 part by weight of an initiator at 0-10 DEG C, heating to 20-30 DEG C, and carrying out polymerization reaction for 30-60 minutes; and 2, adding 100-150 parts by weight of a silane-protected hydroxyl acrylate monomer and 50-60 parts by weight of an organosilicon polymer into the mixture obtained in the step 1 under a stirring condition, and carrying out a polymerization reaction at 20-30 DEG C for 30-60 min to obtain an acrylic resin product. The acrylic resin has the advantages of good thermal insulation effect, good coating effect exactly similar to granite texture, good toughness, and no addition of any color paste. And the product is suitable for public places, suitable for modeling, not easy to fade and long in service life.
Description
technical field [0001] The invention relates to the field of coatings, in particular to an indoor thermal insulation coating. Background technique [0002] In northern my country, especially in the northeast, a large amount of coal is used for heating in winter. Under the premise that the country is vigorously advocating low carbon and low emissions, it is mandatory to require energy-saving insulation for residential and public buildings. Energy-saving insulation for building walls has become increasingly popular. Attention, the government and enterprises are looking for ways to keep buildings warm and reduce the use of coal. At present, wall insulation mainly adopts methods such as pasting insulation boards on external walls and painting paint. Paint is the first choice for building wall decoration materials. Wall insulation can not only Solving the problem of thermal insulation and relatively thinning the thickness of the wall is an effective energy-saving way to achieve bui...
