Problems solved by technology

Because the microbead material used is a hard material with a high content, the paint film cannot cover the fine cracks on the wall
At the same time, the microbead material is easy to pulverize, and the reflective heat efficiency of the reflective particles is greatly reduced after pulverization and c

Example Embodiment

[0029] The elastic reflective thermal insulation architectural coating of this example is an elastic reflective thermal insulation architectural coating used for exterior walls in hot summer and cold winter areas or areas with hot summer and warm winter. It is made by mixing the following raw materials by mass fraction: pure acrylic elastic resin emulsion 20%-40%, silicone resin emulsion 20%-30%, hollow polymer particles 6%-15%, reflective raw material 5%-15% , lead-free pigment 12%~25%, Rohm and Haas polymer dispersant 0.1%~0.5%, Nopco defoamer 0.1%~0.5%, wetting agent 0.1%~0.3%, BYK leveling agent 0.2%~0.5%, BYK UV Absorption Stabilizer 0.1%~0.3%, Toloy Co., Ltd. Anti-mold and Antibacterial Agent 0.1%~0.2%, Coalescence Auxiliary 0.5%~2.5%, Deionized Water 5%~ 25%.

[0030] The preparation method of the elastic reflective thermal insulation architectural paint of the present invention is as follows: 0.1%-0.5% of Rohm and Haas polymer dispersant, 0.1%-0.5% of Nopco defoamer, ...

Abstract

The invention discloses an elastic, reflective and heat-insulation coating and a preparation method thereof. The elastic building coating comprises, by mass, 20-40% of a pure acrylic elastic resin emulsion, 20-30% of a silicone resin emulsion, 6-15% of hollow polymer particles, 5-15% of a reflective raw material, 12-25% of a leadless pigment, 0.1-0.5% of a polymeric dispersant, 0.1-0.5% of an antifoaming agent, 0.1-0.3% of a wetting agent, 0.2-0.5% of a leveling agent, 0.1-0.3% of an ultraviolet light absorption stabilizer, 0.1-0.2% of a mildew inhibition antiseptic, 0.5-2.5% of a film forming assistant, and 5-25% of deionized water. The elastic, reflective and heat-insulation coating adopting the pure acrylic elastic resin emulsion and the elastic silicone resin emulsion can realize paint film elasticity and fine crack coverage, and makes the contamination resistance of the paint film be better than that of paint films formed by traditional elastic coatings and traditional heat insulation and reflection coatings.

Description

technical field [0001] The invention relates to the technical field of water-based architectural coatings, in particular to an elastic reflective heat-insulating architectural coating and a preparation method thereof. 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. For example, in hot summer and warm winter or hot summer and cold...
