Background technology
China is an ancient and civilized country, and a lot of historical and cultural heritages are arranged, and has extraordinary research, preservation and ornamental value.But a lot of historical relics, destruction is in various degree suffered in the pollution of in bad repair with age and environment.The lacquer that historical relic's protection is used is developed under this background and should uses.
Conventional acrylic resin sealing base material forms fine and close paint film, and moisture can't discharge, and along with the increase of body of wall moisture pressure, paint film bubbles easily, ftractures and comes off because of reasons such as dewfall, and the long-term moisture that causes is assembled, and easily causes floating sand, and cohesive force descends.
Its particle diameter of silicone resin reaches nano level, is seeped into the depths of basic unit after the construction by the capillary action very permeable, can not form the successive paint film, has the high ventilation property of breathing, and water vapor can freely come out from body of wall, and water molecules can not enter from the outside.
Silicone resin itself has very strong hydrophobicity performance, meets not swelling of water.Because silicone resin is similar to inorganic molecular structure, silicon resin coating fireproof performance is strengthened greatly than common coating, and weather resistance is splendid.The network structure of silicone resin is similar to quartz and water glass, and silicone resin is more far better than the thermotolerance of common acrylic resin, and being heated does not plastify, and pollutent contamination chance is little, so paint film has high contamination resistance.
Silicon resin coating does not change the color of original basic unit, keeps original style, just concrete, cement basic layer is played a good protection.
Organosilicon not only can be used on the historical relic of concrete substrate as filmogen, can be used on the Shimizu concrete building construction equally.Clear-water concrete has the composition of inorganic silicate, and the basic unit that also contains silicone ingredients and silicate in the silicone resin has good bonding force.
Comprehensive above various factors, cultural relics preservation agent is the pure silicon cold coating, uses on historical relic and buildings more and more.
Summary of the invention
The objective of the invention is to remedy the deficiencies in the prior art part, and basal plane lacquer that the historical relic's protection of a kind of simple for production, excellent performance, long service life uses and preparation method thereof is provided.

Another kind is a solid color enamel
This coat with lacquer preceding 15 raw materials and consumption identical with translucent colored paint outside, carbon black colored paint mass percent is 0.05-0.1.
Basal plane that historical relic's protection is used lacquer making method: 8% water, frostproofer, dispersion agent, pH value conditioning agent, 1% defoamer, wetting agent are added disperse in the cylinder earlier, dispersion is 5 minutes under the rotating speed of 300~400rpm.And then add coarse whiting, sericite, after 1200~1600rpm high speed dispersion to the fineness of slurry is 60 μ m, speed is reduced to 300~400rpm, add remainder water, the pure silicone resin of water-based, the pure organic silicon hydrophobic auxiliary agent of water-based, benzene emulsion, film coalescence aid and remaining defoamer again under the state that stirs, after treating the bubble completely dissolve, add acrylic thickener and polyurethane thickener and regulate viscosity, then, according to the color of on-the-spot base material, mix colours with carbon black color slurry at random.
The pH value conditioning agent is a kind of surfactant of regulating whole system potential of hydrogen, makes the pH value of system and the pH value basically identical of construction substrate.
Wetting agent is a kind of surfactant, makes powder easily by water-wet, is liquid-solid property from the gas-solid inversion of phases.
Dispersion agent is a kind of surfactant, can disperse and stabilising system in water-ground limestone and some kinds of powders in the mica powder.
Defoamer is to eliminate in the production process and the bubble that is generated in the construction process.Make coating have the apparent effect of good stability in storage, application property and paint film.
Frostproofer is the material of low freezing point classes such as ethylene glycol or propylene glycol.
Water-based pure silicon resin is the several prods of German Wa Ke company.Benzene emulsion is the ultra-fine grain diameter emulsion of BASF Aktiengesellschaft.
Film coalescence aid is the lauryl alcohol esters product of U.S. Yi Shi Man.
Thickening material is some kinds of products such as 430 and 278 of the TT-935 of U.S. Rhom and Hass, RM-2020 or this company of hamming.
To be the carbon black pigment powder grind to form the material of pulpous state through shredder to carbon black color slurry, can directly join in the coating, and the color that is used for regulating coating makes the solid colour of itself and base material.Carbon black has superpower opacifying power, can effectively cover in the color of original base material.
Construction technology is:
Translucent colored paint construction process is:
A. processing base level: before base treatment, body of wall needs the maintenance of certain hour, and the curing time in general new cement wall surface winter is 28 days, and the curing time in summer is 14 days.Maintenance is arrived the pH value of basic unit less than 10, and water ratio carries out processing base level again after 10%.
Should thoroughly remove loose, peeling, hollowing, atomizing basic unit, remove pollutents such as dust, greasy dirt, repair then, repair that the color of basic unit's integral body can be inconsistent later, produce aberration.At this kind situation, available translucent coating polishing or solid color enamel are brushed, so that whole color is consistent.
B. polishing: be to repair and the measure taked at local small area.Can carry out the scene according to the repairing situation of basic unit and transfer color, be transferred to a former basic unit look and repair a color between the look, pick the coating that mixes up with cloth and carry out wiping, with the value of chromatism of minimizing two places in the periphery of repairing area with translucent cultural relics preservation agent.Till with the naked eye not seeing.
C. spray cultural relics preservation agent varnish: press the A component: the mixed of B component=10: 1 is good, and the water of converting 10 times again dilutes.Directly evenly spray on the object plane, generally spray twice.In order to make protective material reach good perviousness, back one time and then last time directly spraying must pitch time.Spraying must put in place, and the spray of leakage and uneven phenomenon can not be arranged.With joining with usefulness, allocated the same day in the use, and finished using the same day.
This product belongs to aqueous product, and service tool cleans with clear water and gets final product.
3. the solid color enamel construction process is:
A. processing base level: the basal plane maintenance is identical with translucent colored paint.
Should thoroughly remove loose, peeling, hollowing, atomizing basic unit, remove pollutents such as dust, greasy dirt, repair then, the area of Xiu Buing is very big if desired, can't change the aberration of base material by polishing, just can cover the color of ground by the construction solid color enamel fully, make its color that keeps coating, but this kind color also can not depart from very much the color of original basic unit.
B. roller coating or spraying solid color enamel: directly carry out roller coating or spray real look cultural relics preservation agent after base treatment finished.Can construct one to two time according to practical situation.
