The invention is characterized by special components and preparation method of the paint, and provides an environmentally-friendly optical and thermal radiation-resisting nano-composite metal surface paint of which the solar radiation reflectivity is over 84.4 percent at 410 to 1,000nm, and a preparation method thereof.
Description
Technical field
The present invention relates to used coated material in a kind of metallic surface and preparation method thereof, especially, can be coated in thermal-radiating anti-optical heat radiation nano composite topcoating of metallic surface reflected light and preparation method thereof by special manufacturing method
Background technology
At present on the market the steel plate steel construction in the moving room of color steel roof, metal tank, silo bunker, petrochemical pipe surface, freight container, refrigerator car, mobile building, automobile holder, board house etc., scarcely possesses heat insulating function, part has the also of heat insulation and heat control function to adopt silver paint to carry out application more, but silver paint not only heat-proof quality is not good enough, torridity summer also needs it is carried out the trickle cooling, expended a large amount of HYDROELECTRIC ENERGY, silver paint belongs to oil paint simultaneously, and environmental hazard is strong.
The metallic insulation coating of emerging in large numbers recently also has problems, and number of patent application is that 03117347.0 grain, bunker storehouse nano heat-insulating reflective coating adopt vermiculite, sepiolite, ceramic bubbles, float pearl, pearlstone etc. and reach cooling-down effect for main lagging material reduces thermal resistance coefficient; Number of patent application is that 02109969.3 nanometer acrylic acid microemulsion, water-thinned heat reflecting and isolating paint and manufacture method thereof and number of patent application are 03111863.1 waterborne epoxy modified acrylic heat-reflecting insulating coating, though the oil paint improves to some extent, but its environment for use also has been to use organic solvent, does not reach environmental protection truly.
Summary of the invention
In order to overcome the technical problem that existing metallic insulation coating exists, the invention provides anti-optical heat radiation nano-composite coating material of a kind of environment-friendly type and preparation method thereof, this material is an environment-friendly type, pass through special manufacturing method, can be coated in the metallic surface and reach, thereby realize anti-optical heat radiation function in normal temperature quick-drying curing.
The technical solution adopted for the present invention to solve the technical problems is:
The anti-optical heat radiation nano-composite coating material of metallic surface environment-friendly type, its proportioning composition is expressed as follows according to massfraction:
