Description

A kind of inorganic silicate humidity controlling coating and preparation method thereof

Technical field

The present invention relates to technical field of coatings, particularly relate to a kind of inorganic silicate humidity controlling coating and preparation method thereof.

Background technology

Inorganic aqueous silicate coating is applied to bridge, boats and ships, offshore oil facility, various storage tank and steel rust prevention engineering by advanced countries such as American-European and Japan already.And because this product can be directly and the characteristic of cement generation chemically crosslinked, during for the cement works thing, its sticking power, physical property, voltinism also are better than organic coating.

Existing humidity controlling coating mainly divides two kinds: a kind of is the powder humidity controlling coating, and the operation of this kind coating is difficult for, and dust is very big to harm.Another kind is the emulsion paint type, and it is main base-material that this kind coating adopts organic synthetic resin, and arrange in pairs or groups other auxiliary agents and color stuffing form; But because its organic composition is more, the smell aspect is difficult to avoid, and needs in addition to add more sterilant and carries out antibiotic; And because itself and contactant surface are physical attachment, relatively poor for the sticking power on some more coarse potter's clay or mineral material surface, paint film peels off easily.

Summary of the invention

In order to address the above problem, the object of the invention is to, a kind of inorganic silicate humidity controlling coating is provided; This coating has overcome in the preparation manipulation process dust on the one hand can accomplish odorlessness on the other hand to the injury of human body, is easy to simultaneously be attached to more coarse material surface.

Two of purpose of the present invention provides the preparation method of described inorganic silicate humidity controlling coating.

The present invention is achieved through the following technical solutions:

A kind of inorganic silicate humidity controlling coating is comprised of the following material that calculates according to weight percent:

Preferably, described silicate is that mass concentration is 29% potassium silicate or sodium silicate solution, and is main as main base-material in the present invention.

Preferably, described protruded packing is diatomite or zeolite powder; Be mainly used in absorbing, discharge moisture and regulate humidity.

Preferably, described filler is 700 purpose coarse whitings or grey calcium powder.

Wherein, described water is as the preferred distilled water of primary solvent; Defoamer is used for suppressing and the system of elimination foam, preferred BYK-024; That wetting dispersing agent rises is wetting, dispersion and stabilization, preferred EFKA4560; Anion releasing is used for keeping with fresh air, the rock ASC-01 in sky; Titanium dioxide is used for providing opacifying power, the preferred R-706 of Du Pont; Mierocrystalline cellulose is used for regulation system viscosity, preferred Tao Shi QP30000; Bamboo charcoal powder is used for absorbing formaldehyde; The preferred Tao Shi AMP-95 of multifunctional assistant; The preferred Sol RS of sanitas; Benzene emulsion is as the prothetic group material, preferred BASF; Thickening material is the polyurethanes thickening material, preferred Ke Laien AT10.

The method for preparing described inorganic silicate humidity controlling coating; Comprise and be prepared as follows step:

Steps A, silicate and the water of described amount are put in the reactor, and under 400～600rpm, stirred 3～8 minutes, obtain finely dispersed mixture I;

Step B, add defoamer, wetting dispersing agent and the Sodium hexametaphosphate 99 of described amount in the steps A in the gained mixture I, and under 400～600rpm, stirred 3～8 minutes, obtain finely dispersed mixture II;

Step C, add negative ion releasing agent, titanium dioxide, Mierocrystalline cellulose, protruded packing, bamboo charcoal powder and the filler of described amount in the step B in the gained mixture II, and under 1300～1600rpm, stirred 25～35 minutes, obtain finely dispersed mixture III;

Step D, add multifunctional assistant, sanitas, benzene emulsion and the thickening material of described amount in the step C in the gained mixture III, and under 100～150rpm, stirred 10～20 minutes, obtain described inorganic silicate humidity controlling coating.

The main base-material (filmogen) that the present invention uses is silicate solutions, divide from classification, belong to the inorganic paint category, and from the mechanism of action, be that silicate solutions and ground produce chemical action, be combined closely with ground, (simple physics infiltration is because just physics infiltration is relative relatively poor with the ground combination than prior art on work-ing life, after humidity surpasses hygroscopic limit or the certain number of times of moisture adsorption and releasing, film can inner water-filling and bubbling come off) to grow.

The present invention is by special chemical action between each material in the prescription, so that very fine and close between ground and the coating in the use procedure, be difficult for bearing mould (itself having splendid mildew-resistant effect), mainly be the damping in the inorganic paint.Only have the humidity of adjusting could prevent dew, mildew-resistant, regulating humidity is the sufficient condition of anti-dew, mildew-resistant.Moisture absorption is in order to reduce indoor humidity, for dewfall not; Moisture releasing is to be unlikely to contain water excess and to produce mould in order to make to film.

The present invention is owing to make water as solvent, not only environmental protection does not contain APEO, ultralow VOC, and increases cooperation usefulness between the adsorption by protruded packing, bamboo charcoal powder and negative ion releasing agent self and the three, can accomplish odorlessness, when absorbing decomposing formaldehyde, long term maintenance is with fresh air; Especially the cooperation of other auxiliary agents, so that the present invention in the situation of not adding sterilant, has good germ resistance, and nonflammable, can be used for the harsh ground such as coarse potter's clay or mineral material surface.
