Water montmorillonite nano composite heat insulating waterproof paint and preparation method thereof

Abstract

The invention discloses water montmorillonite nano composite heat insulating waterproof paint and a preparation method thereof. The water montmorillonite nano composite heat insulating waterproof paint comprises the following ingredients in percentage by mass: 30 to 35 percent of nano composite emulsion, 10 to 15 percent of polymer emulsion, 10 to 15 percent of rutile-type titanium pigment, 10 to15 percent of organic modified nano montmorillonite, 5 to 10 percent of nano oxide, 0.3 to 0.35 percent of pH adjusting agent, 0.50 to 0.65 percent of film-forming additive, 0.35 to 0.4 percent of elastic foam killer, 0.20 to 0.30 percent of wetting agent, 0.10 to 0.15 percent of dispersion agent, 0.50 to 0.65 percent of anti-freezing agent, 0.10 to 0.15 percent of sterilization antiseptic and 20to 25 percent of water. The water montmorillonite nano composite heat insulating waterproof paint not only has good compatibility, dispersion performance and good stability, but also has good water resistance, heat insulation, environmental protection, outdoor weather resistance and good adhesive attraction and has an antibacterial self-cleaning function.

Description

technical field [0001] The invention relates to a thermal insulation and waterproof material for building exterior walls, in particular to a water-based nanocomposite thermal insulation and waterproof coating and a preparation method thereof, belonging to the production field of building energy-saving and environmental protection coatings. Background technique [0002] Since the 1970s, the world's climate has warmed, and the earth's energy has been increasingly depleted. Building energy consumption accounts for 30% to 40% of human energy consumption, and most of them are used for heating and air conditioning. It is of great practical significance to develop thermal insulation coatings, especially thermal insulation coatings for exterior walls of buildings that are closely related to human life. The waterproof quality of building exterior walls is also an important indicator for evaluating the quality of construction projects. Therefore, the development of waterproof and th...
