Description
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 uvioresistant, high-temperature resistant coating for wall.
Background technology
In prior art, skin coating commonly used is mostly to be coating prepared by base-material with vinylbenzene-ACRYLIC EMULSION, pure acrylic latex or elastomeric propylene yogurt liquid.Its shortcoming is to produce 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, owing to there being vinylbenzene in coating, be material, smell is quite dense; When exterior wall applies, smell distributes in a large number in atmosphere, has caused pollution; And the set time of such coating is relatively long, therefore, should be noted that Changes in weather during coating, in the rainfall connected, can not construct, therefore, larger limitation is arranged.In the NORTHWEST CHINA area, the sweltering heat in summer, sun heat radiation intensity is high, and the body surface temperature can be up to more than more than 70 degrees centigrade, 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 the solar heat reflection function, do not have the effect of cooling energy-saving.
Because the temperature of the outer surface of building shined upon for a long time is lasting, raise, 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 the 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, reflect the absorption reduced the sunlight heat by raising, 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 there is certain toxicity in traditional reflective insulation material, and unstable chemcial property, is difficult for prolonged preservation, heat-reflecting heat-insulating performance and reaches in time 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 again to have sticking power preferably, lower cost and better simply preparation method.
Summary of the invention
For the deficiency existed on prior art, the invention provides a kind of unioresistant, high-temperature resistant coating.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of environment-friendly type building beyond the region of objective existence wall uvioresistant, high-temperature resistant coating, it is by the A component, B component and component C form, each component consists of by weight: contain following material and content: based on polyaspartic ester resin 25-35 part, 20 parts of aromatic hydrocarbons mixed solvents, nanometer scale ceramics powder 8-10 part, 2～4 parts of mica powders, diacetone alcohol 10-18 part, ethylene glycol monobutyl ether: 3～8 parts, 7～11 parts of the cellulose thickener solution of 2% mass percent, 1.0～1.4 parts of the polyphosphoric acid salt dispersant solutions of 10% mass percent, emulsifying agent: 1～3 part, sodium hydroxide: 0.1～0.3 part, ethanol: 30～50 parts, deionized water: 70～100 parts, titanium dioxide: 140～180 parts, component B, by by weight, includes following material and content: coating curing agent: 0.02～1 part of 3～5 part, initiator, dispersion agent 1, flow agent 0.6, defoamer 0.3, deaerating agent 0.3, 25 parts, modification Ammonia solidifying agent, daconil M: 2～4 parts, dry film mould inhibitor: 5 ~ 3 parts, component C is environment protection colour mixed phase mineral dye, skin coating described above, it prepares by the following method:
The first step: each raw material of weighing: based on polyaspartic ester resin 25-35 part, 20 parts of aromatic hydrocarbons mixed solvents, diacetone alcohol 10-18 part, ethylene glycol monobutyl ether: 3～8 parts, emulsifying agent: 1～3 part, sodium hydroxide: 0.1～0.3 part, ethanol: 30～50 parts, deionized water: 70～100 parts, titanium dioxide: press 18～22 parts of titanium dioxides for 140～180 parts, 8～15 parts of talcum powder, 5～10 parts, calcium carbonate, 2～4 parts of mica powders, 7～11 parts of the cellulose thickener solution of 2% mass percent, 1.0～1.4 parts of the polyphosphoric acid salt dispersant solutions of 10% mass percent take and are separated,
Second step: abrasive grains raw material: titanium dioxide, talcum powder, calcium carbonate, mica powder are mixed and be ground to particle minimum diameter≤50 μ m by shredder, the fine particle that obtains mixing,
The 3rd step: dissolve: the fine particle of the mixing that the second step grinding is obtained and other raw material that the first step takes are put into reaction vessel together, while being heated to 50～60 ℃, stir, and churning time is 45～60 minutes, obtains mixed emulsion;
