Abstract
The invention discloses reflective thermal insulating coating. The reflective thermal insulating coating is composed of 4-6% of magnesium carbide, 25-35% of fluorine carbon emulsion, 5-12% of nanometer hollow glass fiber, 12-15% of titanium dioxide, 0.7-1.0% of dispersing agent, 0.5-0.9% of anti-foaming agent, 0.5-1.0% of preservative, 20-30% of emulsion resin and 21-32% of de-ionized water by weight. The reflective thermal insulating coating has good heat insulating property and weather resistance.
Description
Technical field
The present invention relates to reflectivity thermal insulating coating.
Background technology
The application of coating in each field very extensive, as exterior wall, car body etc., the requirement of existing coating to heat-proof quality is more and more higher, according to investigations comparative analysis, and hollow glass micropearl type outer wall heat-insulating coating exists following defect: 1. paint film is thicker, and consumption paint amount is large.2. coating surface porous, compact in paint film is inadequate, and cause paint film water tolerance bad, resistance to soiling is poor.3. the finished product paint shelf lives is short, and after general one month, viscosity becomes large, and retrogradation becomes paste, impact construction.4. heat-insulating efficiency is not good enough.
Summary of the invention
In order to improve heat-proof quality and weathering resistance, the invention provides a kind of reflectivity thermal insulating coating.
For achieving the above object, a kind of reflectivity thermal insulating coating, according to weight percent meter, is prepared from by following raw material;
Magnesium carbide 4%-6%
Fluorine carbon emulsion 25%-35%
Nano-hollow glass fibre 5%-12%
Titanium dioxide 12%-15%
Dispersion agent 0.7%-1.0%
Defoamer 0.5%-0.9%
Sanitas 0.5%-1.0%
Emulsion resin 20%-30%
Deionized water 21%-32%.
Further, emulsion resin is the one in benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex.
The invention has the beneficial effects as follows: owing to adding magnesium carbide, nano-hollow glass fibre and titanium dioxide, therefore, infrared reflectance can reach more than 90%, and heat insulation rate can to 98%.Owing to adding fluorine carbon emulsion, emulsion resin and nano-hollow glass fibre, make the thickness of paint film little, consumption paint amount is little, and pore is few, weathering resistance and water-tolerant.
Embodiment
Below in conjunction with specific embodiment, the present invention is further elaborated.
Reflectivity thermal insulating coating, according to weight percent meter, is prepared from by 4%-6% magnesium carbide, 25%-35% fluorine carbon emulsion, 5%-12% nano-hollow glass fibre, 12%-15% titanium dioxide, 0.7%-1.0% dispersion agent, 0.5%-0.9% defoamer, 0.5%-1.0% sanitas, 20%-30% emulsion resin, 21%-32% deionized water.Wherein, emulsion resin is the one in benzene emulsion, pure-acrylic emulsion, organosilicon crylic acid latex.Described dispersion agent is triethyl hexyl phosphoric acid, sodium lauryl sulphate or methyl amyl alcohol; Described defoamer is polysiloxane-polyether copolymer, and described sanitas is nitrite.
