Problems solved by technology

[0002] At present, some insulation materials are mostly used on the surface of large storage tanks and houses, but the laying of these insulation materials has a lot to do with the flatness of the surface. The insulation layer is thick, has many seams, is heavy, and is not waterproof; in addition, the laying of insulation materials requires a lot of manpower, and the construction is very inconvenient

Abstract

The invention discloses heat insulation paint, which comprises the following ingredients in percentage by weight: 40 to 60 percent of latex, 2 to 10 percent of zirconium dioxide ceramic powder, 5 to 15 percent of hollow ceramic microspheres, 10 to 25 percent of hollow glass microspheres, 2 to 5 percent of aluminum silicate, 1 to 2 percent of titanium pigment, 0.2 to 1 percent of solutizers, 0.2 to 1 percent of defoaming agents, 0.2 to 1 percent of wetting agents, 10 to 20 percent of water and 0.01 to 0.2 percent of rare earth. Meanwhile, the invention also discloses a method for preparing the heat insulation paint. The heat insulation paint provided by the invention has the advantages of thin coating, light weight, good attaching force, long service life and obvious heat insulation effect and is convenient to construct. The problem that heat insulation materials are difficult to be paved on the surface of a large-size storage tank is solved.

Description

technical field [0001] The invention relates to a thermal insulation paint, in particular to a thermal insulation paint used for the outer surface of a large storage tank and the surface of a house and a preparation method thereof. Background technique [0002] At present, some insulation materials are mostly used on the surface of large storage tanks and houses, but the laying of these insulation materials has a lot to do with the flatness of the surface. For some storage tanks with curved surfaces, it is difficult to lay insulation materials, which may cause The insulation layer is thick, has many seams, is heavy, and is not waterproof; in addition, the laying of insulation materials requires a lot of manpower, and the construction is very inconvenient. Therefore, it is a good choice to design a kind of thermal insulation coating to solve this kind of problem. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to address...
