Abstract
The invention discloses a base solution capable of removing acids and alkalis. The base solution capable of removing acids and alkalis contains a mixed saturated solution comprising NaHCO and ethylene diamine tetraacetic acid (EDTA)-Na2, wherein a mass ratio of NaHCO to EDTA-Na2 is (0.1 to 10) : (1.5 to 150). A preparation technology of the base solution capable of removing acids and alkalis is simple. Raw materials of the base solution capable of removing acids and alkalis have low prices. The base solution capable of removing acids and alkalis can resist erosion caused by alkalis and acids. Specially, the base solution capable of removing acids and alkalis can completely resist the erosion caused by alkalis in walls and the erosion caused by external acid substances and thus protecting painted surfaces well.
Description
Technical field
The invention belongs to building material field, specifically, relate to a kind of brush at the liquid at the bottom of the soda acid that removes on new and old cement wall surface, the concrete wall surface.
Background technology
The alkaline components that contains solubility in the body of wall cement is like calcium hydroxide Ca (OH)
2, sodium hydrogencarbonate Na
2CO
3Deng, in the cement ripening process, its metope is strong basicity, even ripe cement wall surface because the intravital moisture of wall exists, also can slowly be taken the alkaline matter in the cement out of metope.Wall construction is to brush one deck putty earlier at cement wall surface or concrete wall surface; Mopping is again found through long-term observation, brushed putty layer after; Alkaline matter can see through putty layer easily and arrive lacquer painting; Lacquer painting under the alkaline environment effect, phenomenon such as to grow dim appear in the lighter, mouldy, variable color, lustre lacking uniformity, weight person efflorescence occurs, comes off.Putty layer receives the erosion of alkaline matter for a long time, phenomenon such as also can cause efflorescence, come off.
For this reason, relevant technologies personnel advocate the method for using seal coat, for example; In CN1517415A, disclose the application for a patent for invention that name is called " a kind of water-based alkali resistant seal coat and evaluation method thereof ", it is this seal coat of brushing earlier before the brush finish lacquer, thereby reaches the protection to finish paint; There are two shortcomings but do like this: on the one hand; The thickness of seal coat is limited, generally has only tens microns, under such thickness, is difficult to accomplish the complete closed to the water-soluble alkaline material; On the other hand, even seal coat has good sealing to alkaline matter, only can quicken the efflorescence of inner putty layer and come off.So find in using that the method for seal coat neither a good solution.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of in the metope soda acid, protection wall surface putty layer and lacquer painting except that liquid at the bottom of the soda acid.
The present invention seeks to realize like this: a kind of except that liquid at the bottom of the soda acid, it is characterized in that: said except that the mixing saturated solution that comprises NaHCO and EDTA-Na2 in the liquid at the bottom of the soda acid, said NaHCO
3With the mass ratio of EDTA-Na2 be 0.1 ~ 10:1.5 ~ 150.
Above-mentioned except that also adding Mierocrystalline cellulose and Z 150PH, 0.05 ~ 0.1% of the mixing saturated solution mass ratio that said cellulosic add-on is NaHCO and EDTA-Na2 in the liquid at the bottom of the soda acid; The add-on of said Z 150PH be NaHCO and EDTA-Na2 mixing saturated solution mass ratio 2 ~ 5%.Add Mierocrystalline cellulose in order to improve viscosity, the sticking power of gaining in strength, prevent the rimose effect, add Z 150PH and make the whole film-forming properties that removes liquid at the bottom of the soda acid, also can improve adsorptivity, can also regulate flowability and viscosity simultaneously except that liquid at the bottom of the soda acid.
Above-mentioned Mierocrystalline cellulose is that Walocel MT 20.000PV is or/and Natvosol.
As optimization, above-mentioned except that NaHCO in the liquid at the bottom of the soda acid
3With the mass ratio of EDTA-Na2 be 0.5 ~ 3:10 ~ 50, the mixing saturated solution mass ratio that said cellulosic add-on is NaHCO and EDTA-Na2,0.05 ~ 0.08%; The add-on of said Z 150PH be NaHCO and EDTA-Na2 mixing saturated solution mass ratio 2 ~ 3%.
Above-mentioned except that NaHCO in the liquid at the bottom of the soda acid
3With the mass ratio of EDTA-Na2 be 1:15, the mixing saturated solution mass ratio that said cellulosic add-on is NaHCO and EDTA-Na2,0.05%; The add-on of said Z 150PH be NaHCO and EDTA-Na2 mixing saturated solution mass ratio 2%.For removing the best proportioning of liquid at the bottom of the soda acid.
Preparation technology of the present invention is very simple, earlier with NaHCO
3And EDTA-Na2 (EDTA Disodium) blending water dissolving is made into saturated solution, and then adds Mierocrystalline cellulose and Z 150PH and stir and get final product.NaHCO
3At the bottom of removing soda acid, form buffered soln in the liquid with EDTA-Na2, add the acid of equivalent, but can only become sodium hydrogencarbonate to yellow soda ash; The alkali that adds equivalent but can only become sodium carbonate by sodium hydrogencarbonate; Yellow soda ash+sodium hydrogencarbonate is exactly one group of PH buffer reagent, and buffering stores away H+ or OH-; In the certain limit, even you have added a lot of H+ or OH-, still have only yellow soda ash and sodium hydrogencarbonate in the solution, it is following how PH can not become its reaction formula: HCO
3 -1=H
+ 1+ CO
3 -2
Beneficial effect: preparation technology of the present invention is simple, the prices of raw and semifnished materials are cheap, and it can not only alkali resistant, can also be antiacid, can resist fully in the body of wall self with the erosion of alkali, erosion that also can anti-external acid material reaches good protection lacquer painting.
