Abstract

The invention discloses an outer-wall thermal insulating paint and a preparation method thereof. The invention is characterized in that the paint is prepared by mixing paint with a thermal insulating substance and comprises following components: the thermal insulating substance, silane coupling agent, emulsion, water, hollow glass microsphere, paraffin, mica, silica and polyacrylamide. The invention also discloses the preparation method of the outer-wall thermal insulating paint. Compared with the prior art, the invention has the advantages that the mixture of thermal insulating substance rectorite and attapulgite is added into the paint, thus increasing the heat-resisting volume of the paint; the characteristics of strong reflecting capacity and good anticorrosion performance of the micasheet are combined with those of the traditional thermal insulating filler-hollow glass microsphere, thus greatly enhancing the thermal insulating capability of the paint; and in addition, the production can be carried out conveniently, raw materials are easily available, and the cost is lower.

Description

technical field [0001] The invention relates to a heat-insulating paint, in particular to a heat-insulating paint containing a substance with excellent heat-insulating performance, and also relates to a preparation method of the heat-insulating paint. Background technique [0002] Thermal insulation coatings are widely used in thermal insulation materials and construction industries. Therefore, the development of an environmentally friendly heat-insulating coating with good heat-insulating performance, corrosion resistance and convenient construction is more and more favored by the industry. At present, the most widely used thermal insulation coatings are thermal insulation materials such as expanded perlite, expanded vermiculite, floating beads, fly ash, diatomaceous earth, asbestos, glass wool, mineral wool, aluminum silicate fiber, etc. To achieve the purpose of heat insulation, such as the patent number is ZL02114836.8 Chinese invention patent: "Hollow microsphere filli...
