Problems solved by technology

This technical scheme utilizes the hydrophilic surface of the water-based stain-resistant heat-reflective heat-reflective coating, so that the pollutants are easily washed away by rainwater, and the stain resistance (%) is 10, but the heat-insulating primer and water-based stain-resistant heat-reflective heat-reflective insulation are required. The purpose of tarnish resistance and heat insulation can only be achieved when thermal paint is used in combination, and its cost is relatively high, and it is inconvenient to use

Abstract

The invention discloses a staining-resistant heat-insulation coating. The staining-resistant heat-insulation coating comprises the following ingredients by part by weight: 15 to 40 parts of film-forming latex, 10 to 40 parts of fluroresin latex, 10 to 30 parts of heat reflection paint, 5 to 15 parts of hollow ceramic micro beads, 8 to 16 parts of packing, 1.5 to 5 parts of additive, and deionizedwater in balancing amount. As the ingredients such as water-based fluroresin latex are added into the film-forming latex, the purposes of staining resistance and heat insulation are realized. The invention further provides a preparation method of the staining-resistant heat-insulation coating, which comprises the following steps: adding the deionized water, part of the additive, the heat reflection paint, the packing and the hollow ceramic micro beads into a grinder; grinding to obtain a slurry; transferring the slurry to a deconcentrator; adding the film-forming latex, the fluroresin latex and the rest of additive into the slurry; stirring till the ingredients are dispersed; and filtering to obtain the staining-resistant heat-insulation coating. Therefore, the preparation technology is simple; the application is easy; and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to a stain-resistant heat-insulating coating and a preparation method thereof. Background technique [0002] Building energy consumption is one of the three main energy consumption in today's society, and the energy consumption generated by cooling such as air conditioners and fans is a very important part of it. Implementing heat insulation measures for building maintenance structures is the main means to reduce building energy consumption. At present, insulation materials such as extruded polystyrene foam board (XPS board) and polyurethane foam board are mainly used. However, materials such as XPS boards and polyurethane foam boards are flammable substances, and there are major safety hazards. Therefore, the development of inorganic heat insulation materials has become an important means of building energy conservation and emission reduction. Regrettably, the cost ...
