Abstract
An alkali-resistant sealing water priming paint is prepared from acrylic emulsion (35-60 wt.%), water (35-60) and assistant (35-60). A method for evaluating its performance features that it is used for a color finish and a sevious condition is simulated as its application environment. Its advantages are high penetrability, high alkali resistance and high storage stability.
Description
Technical field the present invention relates to a kind of building coating, especially is used as the seal coat of latex type coating.The invention still further relates to the evaluation method of this seal coat.
Background technology is building coating in the market, can be divided into two classes, and a class is an oil paint, and another kind of is water-borne coatings.Major part all contains the benzene series solvent in the oil paint, and they have shortcomings such as volatile, scent of, poisonous, contaminate environment in the process of producing, store, using.Though and water-borne coatings is better than oil paint aspect above-mentioned,,, so just destroyed the decorative effect that applies the water emulsion coating on it because base material can ooze out alkaline matter when being used on the base material of conditional request harshness the time; So, must seal base material.Traditional priming paint is because perviousness, and alkali resistance is relative with stability in storage teaches poorly, and when causing being applied on the base material, sealing effect is relatively poor, occurs paint film easily.In order to overcome above-mentioned defective, building coating is had higher requirement to the performance of seal coat especially alkali-resistivity, and traditional priming paint can not adapt to present requirement.
Summary of the invention is in order to overcome the defective of building coating alkali-resistivity difference, and the present invention discloses a kind of novel aqueous alkali resistant seal coat.This seal coat through scientific and reasonable collocation, strengthens its alkali-resistivity by ACRYLIC EMULSION, water, auxiliary agent, even in comparatively harsh alkaline environment, also can effectively prevent the alkali that oozes of basic unit, and its use range also become more wide.
The present invention is achieved like this:
This seal coat is by the ACRYLIC EMULSION of the 35-60% of counting by weight percentage, the water of about 35-60%, and the auxiliary agent of 0.1-1% is formed, wherein:
ACRYLIC EMULSION is an interpolymer latex of polystyrene and acrylic ester.
Auxiliary agent is by the 10-30% defoamer, the 10-30% sanitas, and the 40-60% thickening material is formed, wherein:
Used defoamer is a mineral oil defoaming agent.
Used thickening material is an association type polyurethanes thickening material.
The alkali resistance of the system of selecting for use of emulsion requirement own is relatively good, possesses lower minimum film-forming temperature (MFT) (＜10 ℃), and the particle diameter of latex particle as far as possible little (＜0.3 μ m) so just can guarantee good penetration and sealing effect.
Defoamer should be chosen in the system consistency preferably, and promptly emulsible defoamer so both can satisfy the requirement of froth breaking, can not occur inconsistent oil slick phenomenon again.
Thickening material should be selected to add at the associative thickener of emulsion thickening or at the cellulose thickener of water thickening, comparatively it is desirable to add association type polyurethanes thickening material.
, earlier ACRYLIC EMULSION, water, defoamer, sanitas are mixed in proportion during this seal coat in preparation, stir, and then the thickener soln that interpolation and water are prepared with 1: 4 ratio promptly makes this seal coat.
In the prescription, selected main film forming substance-emulsion because particle diameter is less, ties in other component, thereby has guaranteed system good penetration, alkali resistance, package stability.Even in comparatively harsh alkaline environment, also can effectively prevent the alkali that oozes of basic unit, overcome the defective of traditional priming paint alkali resistance difference, thereby disadvantages such as some paint films can not appear in the latex finish paint that has effectively guaranteed to apply on it, can be used as the supporting seal coat of generic latex exterior coating, multiple layer latex outer wall paint, special-effect latex outer wall paint, therefore it is a kind of ideal environment-friendly type seal coat, has the value of applying.
If seal coat of the present invention large-area applications in construction can also be taked spraying or brushing.
The present invention is the evaluation method of disclosed this seal coat also.
This method is: cooperate a kind of latex toning finish paint and simulate condition more harsh in the practical application and carry out evaluation to its performance with this seal coat, step is as follows:
This seal coat and the seal coat that the prescription of changing emulsion makes are brushed simultaneously on undressed asbestos plate, directly apply finish paint after dry 5-7 hour, finish paint adds the ultramarine color paste toning of 6-10%, dry about 24 hours, then asbestos plate is lain against on the sponge that is immersed in the basic solution, observe variation after seven days.Wherein:
The emulsion content that cooperates the finish paint system of this seal coat is 20-40%.
Harsh condition is to apply the model that finishes to lie against on the sponge that is immersed in all the time in the basic solution.
The basic solution concentration of using is 3-8%, and solution can be basic solutions such as NaOH, KOH.
Sponge highly is 1-2cm.
Can find to contrast model after the observation and tangible accumulation of salt in the surface soil dipping and foaming can occur, and the model of the present invention's prescription does not change.
This evaluation method has been simulated the alkaline condition in the reality preferably, can very easily make intuitively this kind seal coat and estimating.

Embodiment
Recently prepare this seal coat by following weight percent:
50% ACRYLIC EMULSION 6515 (Eternal);
49.5% water;
0.1% defoamer NXZ (Cognis);
0.1% sanitas LFM (Cognis);
0.3% thickening material 1514 (Cognis).
Compare according to above-mentioned evaluation method, wherein basic solution adopts 5% NaOH solution, and sponge highly is 1.5cm, can find:
Tangible accumulation of salt in the surface soil dipping and foaming appear on the contrast model already, and the model no abnormality seen of the present invention's prescription.All are normal in the package stability experiment with up-to-date style lacquer.
This experimental result has illustrated that this kind seal coat has good alkali-resistivity, even also can effectively prevent the alkali that oozes of basic unit in comparatively harsh alkaline environment.
