Heat insulating and preserving coating for exterior wall of building

Abstract

The invention provides a heat insulating and preserving coating for an exterior wall of a building. The heat insulating and preserving coating comprises the components: polymer emulsion, functional filler, titanium dioxide, a thickening agent, a wetting agent, a dispersing agent, a defoaming agent and water, wherein the functional filler is a self-prepared fly ash zeolite molecular sieve; the polymer emulsion is soft styrene-acrylic emulsion. The coating has the advantages that a coating layer formed on a building wall body is outstanding in performance, the heat insulating and preserving effect is superior to that of other similar heat preserving coatings, and the temperature difference can reach more than 10 DEG C compared with a blank phase; in addition, the heat insulating and preserving coating has the advantages of being environmentally-friendly, nontoxic, high in adhesive force, difficult to crack, easy to construct, etc., is applicable to the coating layer for heat preserving of the exterior wall of the building, and shows a remarkable environmental protection and energy saving effect.

Description

technical field [0001] The invention relates to a thermal insulation material, and also relates to the technical field of coal-based solid waste recycling, in particular to a thermal insulation coating used on the surface of building exterior walls. Background technique [0002] With the rapid development of human science and technology and economy, human energy consumption is increasing day by day. Among them, building energy consumption has accounted for 30% to 40% of the total energy consumption in the country. my country has promulgated a series of policies and regulations, mandatory energy-saving measures must be taken for buildings. The improvement of energy-saving technology of building exterior wall enclosure structure can improve the thermal insulation performance of buildings, which can effectively reduce building energy consumption, which is of great significance to the reduction of energy consumption of the whole society. The main significance of the insulation...

Problems solved by technology

[0003] At present, most of the thermal insulation materials on the market use expanded perlite, diatomaceous earth, vermiculite, asbestos, etc. as thermal insulation fillers. A relatively static state, thereby blocking the transfer of heat and improving the thermal insulation performance of the material; but their common shortcomings are poor stability, poor thermal insulation effect after moisture absorption, and low mechanical strength
