Description

A kind of environment-friendly type building beyond the region of objective existence wall uvioresistant, 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 environment-friendly type building beyond the region of objective existence wall uvioresistant, high-temperature resistant coating.
Background technology
In prior art, conventional skin coating is mostly be coating prepared by base-material with vinylbenzene-ACRYLIC EMULSION, pure acrylic latex or elastomeric propylene yogurt liquid.Its shortcoming produces fine cracks after being applied to body of wall, puts forth effort poor, anti-pollution characteristic and poor performance at low temperatures etc.; In addition, be material owing to there is vinylbenzene in coating, smell is quite dense; When exterior wall applies, smell distributes in an atmosphere in a large number, causes pollution; And the set time of such coating is relatively long, therefore, should be noted that Changes in weather during coating, can not constructs in the rainfall connected, therefore, have larger limitation.In NORTHWEST CHINA area, summer is hot, and sun heat radiation intensity is high, and body surface temperature can up to more than more than 70 degrees Celsius, and winter-spring season then dust storm is very large, very strong to the wind abrasion of paint film.Anti-blown sand coating practical in the market adopts urethane, and weathering resistance and anti-blown sand performance generally, and do not have solar heat reflection function, do not have the effect of cooling energy-saving.
Because the constant temperature of the outer surface of building shined upon for a long time raises, the temperature of the material of construction outside surfaces such as outer surface of building is cement, concrete, ceramic tile, metal, insulating brick can reach 40-50 DEG C, on color steel, water-proof material, temperature can reach 60 DEG C, reaches the temperature of boiling hot people.Under such outer surface of building high temperature, in habitat, the inevitable rising of the temperature of plant floor etc., live to normal human subject, material deposits, the safety of equipment all causes very large impact, likely can produce the great potential safety hazards such as blast, if temperature is too high, need cooling, cause the significant wastage of the energy simultaneously.
In order to reduce the thermal radiation of the sun, by improving the absorption of reflection minimizing to sunlight heat, therefore there is heat insulation, to reflect functions such as lowering the temperature, anticorrosion coating arise at the historic moment, become reducing sun heat radiation harm to a great extent in the urgent need to, these coating there are fabulous market outlook of painting industry.But there is certain toxicity in traditional reflective insulation material, and unstable chemcial property, not easily preserve for a long time, heat-reflecting heat-insulating performance in time and the change of environment and the defect of change 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 need again good sticking power, lower cost and better simply preparation method simultaneously.
