Description

A kind of unioresistant, high-temperature resistant coating

Technical field

The present invention relates to a kind of new anti-corrosion coating and preparation method thereof, more particularly, relate to a kind of unioresistant, high-temperature resistant coating.

Background technology

In NORTHWEST CHINA area, summer is hot, and sun heat radiation intensity is high, and body surface temperature can be up to more than more than 70 degrees Celsius, and winter-spring season dust storm is very large, very strong to the wind abrasion of paint film.Practical anti-blown sand coating adopts urethane in the market, and weathering resistance and anti-blown sand performance are general, and there is no solar heat reflection function, do not have the effect of cooling energy-saving.

The lasting rising of temperature due to the outer surface of building being shined upon for a long time, outer surface of building is that the temperature of the material of construction outside surfaces such as cement, concrete, ceramic tile, metal, insulating brick can reach 40-50 ℃, on color steel, water-proof material, temperature can reach 60 ℃, reaches the temperature of scalding people.Under such outer surface of building high temperature, in habitat, the inevitable rising of temperature in factory building workshop etc., to normal human subject live, material is deposited, the safety of equipment all causes very large impact, likely can produce the great potential safety hazards such as blast, if excess Temperature, need cooling, caused the significant wastage of the energy simultaneously.

In order to reduce the thermal radiation of the sun, by raising, reflect the absorption reducing sunlight heat, therefore having coating heat insulation, that reflect functions such as lowering the temperature, anticorrosion arises at the historic moment, become having reduced to a great extent sun heat radiation harm in the urgent need to, these coating and thering are fabulous market outlook of painting industry.But traditional reflective insulation material exists certain toxicity, and unstable chemcial property, be difficult for prolonged preservation, heat-reflecting heat-insulating performance in time and the variation of environment and the defect of variation etc.Consider above-mentioned practical situation, those skilled in the art is being devoted to study a kind of novel water corrosion-resistant epoxy paint always, replace existing solvent-borne type protective system, and simultaneously need have good sticking power, lower cost and better simply preparation method.
