Abstract

The invention relates to an energy-saving heat-insulation heat-preserving hot plugging material and a preparation method thereof. The energy-saving heat-insulation heat-preserving hot plugging material is characterized by comprising the following components by weight percent: 0.3 to 0.4 percent of dispersing agent, 0.2 to 0.3 percent of defoaming agent, 0.5 to 0.8 percent of penetrating agent, 0.1 to 0.15 percent of polyacrylamide, 0.3 to 0.6 percent of high-temperature glue, 2.5 to 2.9 percent of closed cell perlite, 0.8 to 1.0 percent of hollow glass microbead, 0.7 to 0.9 percent of nano hollow ceramic microbead, 2.6 to 2.9 percent of bentonite, 2.0 to 3.0 percent of ceramic fibers, 0.5 to 1.0 percent of based-titanium whisker, 0.5 to 1.0 percent of polycrystalline aluminum oxide fibers, 0.1 to 4.0 percent of asbestos and the balance of water; the sum of the weight percentage is 100 percent. The energy-saving heat-insulation heat-preserving hot plugging material has the characteristics of thin coating, light weight, good heat-preserving effect, long service life, environment friendliness, recyclability and the like. The method is mature and reliable in process, and the prepared hot plugging material is stable in performance; convenience in construction is realized, construction by driving a car can be realized, and the difficulty that the heat-preserving material is difficult to pave on the surface of equipment such as a boiler top, a boiler bottom and a steam turbine body can be solved.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and in particular relates to an external thermal insulation coating for equipment and pipelines in electric power, chemical industry, petroleum and other industries and a preparation method thereof. Background technique [0002] At present, most of the insulation materials used in equipment or pipelines are laid in layers, which will inevitably produce seams, and the existence of seams will inevitably lead to an overall decline in the insulation effect; and the laying of some spherical or heterogeneous equipment insulation materials requires welding insulation nails Additional auxiliary devices such as grapples, grapples, etc. These auxiliary devices are just good conductors of heat, and their existence will inevitably cause an overall decline in the thermal insulation effect. Traditional thermal insulation products are mostly thick-layer thermal insulation materials. The th...
