Preparation of Energy-saving Exterior Wall Thermal Insulation Coatings

The preparation of energy-saving exterior wall thermal insulation coating is as follows:

1. Main raw materials

Self-crosslinking acrylic copolymer emulsion and deionized water, nano anti-aging agent, imported rutile titanium dioxide and infrared radiation pigments, ceramic hollow microspheres and imported additives (ammonia salt dispersant and wetting agent produced in Japan, anti-corrosion agent produced in Britain) Anti-mildew and anti-algae agent, British thickener, film-forming aid and defoamer produced by Eastman Company of the United States), designed and manufactured through formula optimization.

2. Coating production equipment

High-speed disperser, paint mixing tank, sand mill, Diaphragm Pump, precision trap, thick slurry pump, etc.

3. Production formula of energy-saving exterior wall thermal insulation coating

4. Production process of energy-saving exterior wall thermal insulation coating

Add deionized water into the dispersion tank, add dispersant and defoamer and stir evenly. While stirring, add titanium dioxide and infrared radiation pigments to disperse at a high speed until the fineness is less than 30 μm, and then transfer to the paint mixing tank. While stirring, add anti-corrosion, anti-mildew and anti-algae agents, film-forming aids and antifreeze agents, and slowly add a certain amount of self-linked pure acrylic acid emulsion and defoamer. Control the stirring speed, slowly add the functional hollow additive of heat-insulating coating under stirring, stir until uniform and free of particles, then use thickener to adjust to a suitable viscosity, color (or white), filter and pack. Warehouse after passing the test. The above is the preparation information of energy-saving exterior wall heat insulation coatings compiled by CHINA New Paint Network, I hope it will be helpful to everyone.
