Abstract

The invention discloses a nano thermal insulation reflective coating additive for an exterior wall. The nano thermal insulation reflective coating additive comprises the main components in weight ratio: 160-250 parts of water, 1-2 parts of defoaming agent, 8-12 parts of dispersing agent, 0.5-2 parts of hydroxyethyl cellulose, 400-500 parts of thermal insulation reflective powder, 5-10 parts of nano TiO2 powder, 5-10 parts of nano SiO2 powder, 5-12 parts of ethylene glycol, 5-10 parts of film-forming additive, 200-300 parts of AC-261P waterborne acrylic emulsion and 1.0-2.0 parts of thickening agent. The nano thermal insulation reflective coating additive is prepared by stirring all the components according to the weight ratio. The coating additive for the exterior wall can be used for realizing the thermal insulation reflection of a color coating for the exterior wall, and furthermore, the energy conservation of a building is realized; water is used as a solvent, so that the nano thermal insulation reflective coating additive has the advantages of environment friendliness, exterior wall hydrophobicity, self-cleaning and the like.

Description

technical field [0001] The invention relates to a nano heat-insulating reflective paint additive for exterior walls, in particular to the heat-insulated reflective additive used for color paints to realize building energy saving. Background technique [0002] With the development of the global economy and the improvement of living standards, the demand for resources and energy is increasing. In particular, transportation and building energy consumption account for more than 50% of the total energy consumption, of which building energy consumption accounts for 30-40%. Building energy consumption is mainly used in heating and air conditioning, and improving the thermal insulation performance of buildings is an important way to save energy. Most of the energy on the earth comes from the sun, coal, oil, wind energy and water kinetic energy. The sun radiates energy to the earth's surface at a speed of 1.77×1017J / S, providing living conditions for life on earth, but strong therma...
