Abstract
The present invention relates to coating and production method thereof in a kind of colorful tempering, be characterized in, this coating is mainly by polyvinyl alcohol, dibutyl phthalate (or ethylene glycol), materials such as Sodium hexametaphosphate 99, zinc sulfide white, titanium dioxide, calcium hydroxide, water and tributyl phosphate, whitening agent, benzene emulsion are formed, and its production method mainly is that polyvinyl alcohol dissolving back adds all the other raw materials after the abundant reaction with dibutyl phthalate (or ethylene glycol) again in reactor and the last benzene emulsion that adds that stirs promptly gets finished product with low cost.
Description
The present invention relates to a kind of multicolor finish middle level and spray coating and production method thereof in the colorful tempering that uses.
Multicolor finish is the new decorative material for building that development in recent years is got up, and when the spraying multicolor finish, must have the priming paint and the middle coating intermediate of bottoming usefulness to do the basis.Coating is main film forming substance with vinylformic acid or benzene emulsion mostly in using at present both at home and abroad, and its shortcoming is a complex manufacturing, the cost height.
It is simple to the objective of the invention is to invent a kind of production technique, coating and production method thereof in the low colorful tempering of cost.
The present invention is achieved in that
Coating in a kind of colorful tempering comprises metering water and following raw materials according and weight ratio thereof.
1, polyvinyl alcohol.Be a kind of fine glue after polyvinyl alcohol dissolves, can organically the coating stopping composition be combined as a whole, become the main film forming substance of this coating, but it is poor to be less than 1% o'clock filming function, not only cost is high but also cause that coating is feeding-up, hiding power is poor more than 7%.
2, dibutyl phthalate or ethylene glycol.After the polyvinyl alcohol film forming, when high humidity, be softish, crisp and easy to be broken under the drying regime, so need carry out plasticising handles, what polyvinyl alcohol was had better plastification is dibutyl phthalate and ethylene glycol, according to the consumption of polyvinyl alcohol, should add in the coating and be no less than 0.05% and no more than 0.5% dibutyl phthalate or ethylene glycol or the two and share.
3, Sodium hexametaphosphate 99.This material mainly plays dispersion, prevents sedimentary effect in coating, it is serious to be less than 0.1% o'clock precipitation, is prone to false thickly more than 0.5%, and inconvenience is deposited and constructed.
4, whitening agent.This material has the effect that improves product whiteness, raw material whiteness height can be less with or need not, its control ratio should be 0≤whitening agent≤0.2%.
5, tributyl phosphate.Coating will influence quality product in various degree if produce bubble when making or construct, so need to adopt defoamer to carry out defoaming treatment.Tributyl phosphate is comparatively ideal defoamer, but its consumption is crossed conference reduction paint adhesion, and therefore 0≤tributyl phosphate≤0.5% is advisable.
6, zinc sulfide white and titanium dioxide.These two kinds of materials can improve the over-all properties of coating as stopping composition, improve the whiteness and the opacifying power of coating.Practice shows: 2%≤zinc sulfide white≤6%, 2%≤titanium dioxide≤8% is advisable.
7, calcium hydroxide or calcium oxide.Using this material is one of key of this coating, calcium oxide is met water and is generated calcium hydroxide, construct behind metope as the coating stopping composition, finally become lime carbonate, can improve the hardness and the water tolerance of coating greatly, but, surpass 25% and make the coating overdrying feeding-up if pressing calcium hydroxide calculates, influence coating appearance and construction, therefore 5%≤calcium hydroxide≤25% or quite normal calcium oxide are advisable.
8, benzene emulsion.Benzene emulsion is the novel building glue, and water tolerance and cohesiveness are preferably arranged, and improves the coating over-all properties, then will increase cost but consumption is too high, and therefore 0≤benzene emulsion≤5% is advisable.
According to construction requirement, also can add 0≤talcum powder≤15% or 0≤lime carbonate≤20% or the two in this coating and share and make filler.
It is pointed out that increasing stopping composition in this coating makes its retrogradation, then can doublely do priming paint or make level and smooth light separately has better intensity and water-proof reinforced wall surface paint; After in this coating, adding various pigment, also can directly be used as painting coating.
The production method of coating of the present invention is:
A, will partly measure water and inject reactor and be warming up to 60～85 ℃, and add polyvinyl alcohol, and stop after the dissolving fully heating up, and add dibutyl phthalate or ethylene glycol then, and it is standby to be cooled to normal temperature after it is fully reacted;
B, that Sodium hexametaphosphate 99 is added in an amount of hot water dissolving is standby;
C, that whitening agent is added in an amount of water dissolving is standby;
D, the liquid that a, b, c step are obtained and metering water mix and stir, and add zinc sulfide white, titanium dioxide, calcium hydroxide (or calcium oxide) and also stir;
E, the product that the d step is obtained grind filtration, and the stopping composition that adds benzene emulsion and necessity at last gets product.
Advantage of the present invention is: water-tolerant, strong covering power, cost are low, and production technique is simple.
Following table is the Chemical Composition proportioning (weight %) of 5 groups of embodiment of the present invention
Last tabular go out each form part, all produced ideal product by the method for the invention according to difference construction needs.
