High temperature resistant thermal insulation coating

Abstract

The invention discloses a high temperature resistant thermal insulation coating, containing acrylic emulsion, fluorinated silicone rubber, film forming aid, a dispersing agent, pigment filler, water, and the like. The coating has the advantage of excellent high-temperature resistance so that the coating can be used on the surface of an object at a temperature of -80 DEG C to 1100 DEG C; meanwhile, the coating has the advantage of excellent thermal insulation effect so that the temperature of the surface of the object can be obviously reduced and more than 30% of heat loss can be decreased. The coating can be applied to inside and outside surfaces of all kinds of high temperature pipelines, furnaces and kilns.

Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature-resistant heat-insulating coating. Background technique [0002] Heat pipes will generate heat loss during steam or liquid transportation. The traditional method is to adopt the method of lining rock wool and wrapping iron sheets. The disadvantage of this method is that it is impossible to observe the "running, popping, dripping, and leaking" of the inner wrapping iron pipe. . In addition, the corrosion of pipelines is likely to cause hidden dangers in safety. [0003] The temperature-resistant coatings in the prior art usually have a temperature resistance range up to 700-800°C, and are poor in temperature denaturation resistance and corrosion resistance. Therefore, it is of great practical significance to research and develop a high-temperature-resistant heat-insulating coating that is more resistant to high temperature, has good temperature denaturation resistance, and excelle...
