Abstract

The invention relates to a heat-insulating coating for an external wall and a preparation method thereof. The coating comprises styrene and acrylic ester copolymerization emulsion, a zirconium-aluminic acid ester coupling agent, titanium dioxide, calcium carbonate, sericite powder, hollow microbeads, metal oxide, a leveling agent, a pigment dispersing agent, a bactericide mildew preventive, a pH regulator, hydroxyethyl cellulose and a defoaming agent, the preparation method comprises the following steps: mixing and stirring a filtrate, prepared from the raw materials, and a curing agent according to the weight ratio of (1-2):0.5, to obtain the heat-insulating coating for the external wall. The curing agent is a mixture of 70-90% of silicate solution and 10-30% of water, and is obtained by evenly mixing and stirring silicate solution and water. The heat-insulating coating for an external wall has the characteristics of being strong in chemical resistance, good in weather resistance and stain resistance, water resistance, wear resistance, and dampproof effect, high in glossiness, long in the service life of a coated film, and the like, and also has the reflection and heat insulation functions.

Description

technical field [0001] The invention relates to a preparation method of a heat-insulating paint, in particular to a heat-insulating paint for an exterior wall and a preparation method thereof, and belongs to the technical field of chemical composition and its preparation. Background technique [0002] Building energy conservation is one of the key points of my country's energy conservation work, and external wall insulation has become the main product of building energy conservation. For areas where thermal insulation is the main focus of thermal design, such as severe cold areas and cold areas, external wall insulation is not only reasonable, but also applicable, and has developed rapidly. For hot summer and warm winter regions where thermal design generally only considers heat insulation, or hot summer and cold winter regions where heat insulation is the main focus of thermal design, there is room for further improvement of the current external wall insulation. According ...
