Abstract
A process for preparing building paint features that among used fillers, there is dolomite with molecular formula of MgCO3.CaCO3. After calcining and hydration, dolomite ash with molecular formula of Mg(OH)2.Ca(OH)2 is obtained, which then reacts with CO2 in air to generate magnesium carbonate and calcium carbonate. As said dolomite ash has gelling property and high stability and hardness after air hardening, the properties of paint such as water, brush, alkali, and freeze thaw resistances, weatherability, and adhesion are greatly improved, and the amount of adhesive used in paint is reduced.
Description
The present invention relates to a kind of manufacture method of building coating.
Up to the present, water soluble paint for building generally is compound formulated by mineral dye, filler, chemical assistant and tackiness agent.The performance of coating and cost depend on selected tackiness agent.The coating that with the water soluble resin is tackiness agent is low-grade coating, and as 106,107 coating etc., its cost is lower, but exists water tolerance, abrasion resistance, weathering resistance, adhesion strength poor, easily efflorescence, peel off, shortcoming such as flavescence.Though its performance of coating that with the synthetic resin emulsion is tackiness agent is better, the production process complexity, cost is too high, has been subjected to very big restriction so it is promoted the use of.In order to solve above-mentioned contradiction, the professional research institution of domestic some all is that the coating glue stick with the development high-performance and low-cost is a research direction, but does not make a breakthrough so far.
The manufacture method that the purpose of this invention is to provide a kind of building coating, make the coating of producing with present method have the excellent properties such as water-fast, weather-proof, freeze-thaw-, alkali resistance and adhesion strength height of synthetic resin emulsion class coating, have the low price of water soluble resin coating simultaneously.
In order to achieve the above object, building coating disclosed in this invention comprises in polyvinyl alcohol water soluble resin or synthetic resin emulsion, filler, pigment, chemical assistant and water, the used filler and comprises component A that component A is that molecular formula is Mgco
3Caco
3The calcined dolomite in powder that obtains after the aquation through calcining of rhombspar, the molecular formula of calcined dolomite in powder is Mg (OH)
2Ca (OH)
2
The degree of component A in coating is 15～25%;
The degree of component A in coating is preferably 18～23%.
Above-mentioned polyvinyl alcohol water soluble resin can select for use the urea hydroformylation to handle polyvinyl formal, and its degree in coating is 20%～40%.If use synthetic resin emulsion, then its degree in coating is 5%～20%.Include the phosphoric acid solution of quickly penetrating agent " T " and 10% concentration in the chemical assistant, their degree is respectively 0.01%～0.02% and 1%～2.5%.
Technological process of the present invention comprises the following steps successively
Grind---filtration---packing after going into the defoamer lather collapse.Perhaps in above-mentioned processing step, poly-by the following step after adding urea hydroformylation processing polyvinyl formal:
---packing.
Because the present invention includes component A in prescription, the main component of component A is Mg (OH)
2, Ca (OH)
2, Mg when paint brush is on buildings (OH)
2Ca (OH)
2With airborne CO
2Reaction generates CaCO
3And MgCO
3, MgCO wherein
3The speed that generates is than CaCO
3Faster, and MgCO
3Chemical property stable, have higher hardness and gelling, tackiness agent and filler compound action in they and the coating have improved the water-fast of coating greatly, washability, alkaline-resisting, freeze-thaw-, weathering resistance have improved adhesion strength.This coating is as follows through pressing exterior wall coating material of synthetic resin emulsion GB9755-88 standard test result: more than the water tolerance 96h, more than the alkali resistance 48h, freezing and thawing test is more than 10 times
Accelerated aging test is more than 250 hours
The test of scrubbing property is more than 1000 times
More than the adhesion strength 0.5MPa
Main performance index is the conformance with standard regulation all, by the thin matter decorative paint industrial standards JISA6909 of Japan---1984 prescriptive procedures test, adhesion strength can reach 1.0MPa, on the other hand, because the gelling of calcined dolomite in powder, thereby the performance that makes coating is not mainly determined by the performance of the glue paste that is adopted, but by the compound action of calcined dolomite in powder and tackiness agent, even mainly be that gelling by calcined dolomite in powder self is determined, thereby greatly reduce the consumption of tackiness agent in the prescription, thereby greatly reduce the production cost of coating.
The effect that adds quickly penetrating agent " T " and phosphoric acid solution in prescription is that component A is disperseed in water fast, and improves the stability that coating is stored.
The present invention has created new field for the utilization of the very abundant rhombspar of China's reserves, has opened up the new direction of coating research, is domestic initiation.
