Problems solved by technology

However, the use of these materials not only complicates the construction procedure, but also consumes more internal space due to the large thickness of the coating when used on the interior wall, resulting in a high overall cost.
Especially for old buildings that did not use insulation layer before, it is more difficult to increase the construction of insulation layer

Abstract

The invention relates to a thermal insulation material and a preparation method thereof. The thermal insulation material is prepared by mixing mica, vinyl alcohol, polyethylene vinyl acetate, polyvinyl alcohol, cement, saponite, butyronitrile, epoxy resin, hydroxypropyl methyl cellulose, sodium dodecyl benzene sulfonate, dibutyl phthalate, polyacrylamide and starch ether by adding water, wherein the mica is powder with particle size range from 1 micron to 0.6 millimetre. The preparation method comprises the following steps of: mixing the ingredients, adding water in the ingredients, uniformly stirring the ingredients, coating the obtained pulp on a surface needing thermal insulation, wherein the coating thickness is at least 1.5mm. The thermal insulation material is good in thermal insulation effect, simple to prepare, convenient to construct and low in construction cost, thereby being especially suitable for performing thermal insulation on old buildings.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation, and in particular relates to a thermal insulation material and a preparation method thereof. Background technique [0002] With the increasing energy consumption, efficient use of energy and energy conservation have become one of the most important issues of concern to all human beings. Since the 1990s, my country has promulgated the "Energy Conservation Law" and formulated a series of energy conservation laws and regulations, which put forward specific standards and requirements for energy conservation. At present, a variety of thermal insulation materials can be seen in the market, such as mineral wool, foamed plastics, perlite, resin materials, thermal insulation mortar and so on. However, the use of these materials not only complicates the construction procedure, but also consumes more internal space due to the large thickness of the coating when used on the interior wall, resulti...
