Description
Technical field
The present invention relates to a kind of concrete coating, relate in particular to efficient concrete curing coating.
Background technology
Conventional concrete conservation is accurately weighed according to the design requirements of cement, coarse and fine aggregate and water, stir well coated with straw or immediately after forming grass Lian, in 28 days always kept moist to achieve health purposes.Cement forms saturated tricalcium aluminate and aqua calcis with the mixing water effect in concrete.In this high alkali environment; The continuous aquation of cement clinker forms sulphur tricalcium aluminate, sulfuric acid DFP, celite, tricalcium silicate, Dicalcium Phosphate (Feed Grade) isogel deposition or crystallization and calcium hydroxide crystallization, makes concrete reach ideal intensity and each item performance index until the complete aquation of cement.When maintenance was not in place, cement fully aquation formed gel, obviously influences each item performance index and application functions thereof such as its intensity, density, because its porosity is big, is easy to receive extraneous all kinds of material to corrode, like the sulfate ion fragmentation of can expanding very soon.Particularly carbon dioxide in air is easy to combine to form lime carbonate with calcium hydroxide, makes rebar passivation film destroy rapid corrosion, and various gels are corroded in carbonic acid gas continuation simultaneously and the generation destruction is closed in calcification.
Concrete curing is not only loaded down with trivial details but also time-consuming; And need take construction investment, expense was surprising especially when on-the-spot lack of water need be transported water curing, therefore both at home and abroad already large-scale popularization use concrete curing coating; Spray maintenance coating after the concrete moulding immediately and just can place of water support operation, can save most of water and support expense.
At present, import concrete curing coating is near the laboratory maintenance effect, but costs an arm and a leg, and domesticly seldom adopts.Though homemade concrete curing coating is economical and practical, effect is undesirable.Conventional maintenance is time-consuming expensive and usually do not reach technical requirements.Therefore, it is economical and practical that development and popularization is used, and can meet or exceed the efficient concrete curing coating of laboratory maintenance concrete strength, improves from the concrete curing aspect or guarantee that its quality has just had clear meaning for China.
Summary of the invention
Technical problem to be solved by this invention provides a kind of saving of work and time and the good efficient concrete curing coating of maintenance effect.
For addressing the above problem; Efficient concrete curing coating of the present invention, it is characterized in that: this coating is made up of the raw material of following weight ratio: chlorine partial emulsion 32.0 ~ 42.2%, Z 150PH 0 ~ 2.0%, OP-10 emulsifying agent 0.14 ~ 0.50%, deionized water 28.5 ~ 64.8%, tributyl phosphate 0.50 ~ 0.60%, butanols 0.50%, terepthaloyl moietie 0.36 ~ 0.60%, tsp 0.31 ~ 0.46% are formed with light calcium carbonate filler 0 ~ 32.5%.
Said Z 150PH is 17-99s (H) the type Z 150PH of alcoholysis degree 99.8 ~ 100% (mol/mol), viscosity 20.0 ~ 32.0mpa.s.
The preparation method of aforesaid efficient concrete curing coating is characterized in that: each raw material of weighing at first in proportion is dissolved in tsp in the deionized water then; Add Z 150PH again; After soaking 4 ~ 8 hours under the room temperature, stir on intensification limit, limit, to 96 ℃ of dissolvings fully; Be cooled to 40 ℃ subsequently, obtain Z 150PH liquid; Secondly, in said Z 150PH liquid, add OP-10 emulsifying agent and chlorine partial emulsion, stir, and adjustment pH value to 7.0 ± 0.5, base-material promptly got; At last, in base-material, add tributyl phosphate, butanols, terepthaloyl moietie and light calcium carbonate filler, packing gets product after stirring.
The present invention compared with prior art has the following advantages:
1, the present invention selects for use the superior chlorine partial emulsion of resistance to air loss as host, selects for use the also very superior Z 150PH 17-99s (H) of resistance to air loss as thickening material and protective colloid; The concrete face often has greasy dirt, and is very big to the formation influence of filming, and adds the hydrophilic OP-10 emulsifying agent of an amount of molecule one end oleophylic one end for this reason; The concrete face exists the grains of sand, bubble impression, step etc. also can influence the continuity of filming; Select for use inexpensive tsp as permeate agent; With the OP-10 emulsifying agent synergy that can reduce surface energy, infiltrate in the concrete micropore when making coating form continuous film, strengthen film adhesive; Select for use water as carrier, can significantly reduce cost, avoid environmental pollution; In order to prevent that system from joining and apply the generation influence of air bubbles, selected for use an amount of tributyl phosphate, butanols as skimmer.
2, the present invention is enclosed in mixing water in the concrete, and hydrate does not run off, and moisturely everywhere in the concrete also reaches unanimity; It all is uniformity that hydrated cementitious speed, hydrate distribute; Therefore, the effect of maintenance concrete is excellent, can meet or exceed the intensity (referring to table 1) of touchstone maintenance concrete.
The test of table 1 concrete curing effect comparison
Annotate: 1, this test is accomplished by scape electricity the second stage of the project headquarters matter peace place.2, testing laboratory's maintenance has been done at matter peace place simultaneously, and its ultimate compression strength is identical with the water curing of bag straw bag.
When 3, using, only need the present invention evenly is applied on the concrete body, make the maintenance work saving of work and time; Simultaneously, vertical face is smeared one time after the concrete form removal, after the drying again plane of structure smear one time and get final product, simple and easy to do.
4, the present invention is to the influence of reinforcing bar in the concrete: because the concrete surface is by sealing in advance, though water cut is big in the concrete, reinforcing bar is in saturated Ca (OH)
2In the solution, but the passive film that rebar surface forms naturally can effectively protect it that corrosion does not take place, and after moisture was overflowed gradually, reinforcing bar was still at Ca (OH)
2Crystallization needn't worry to take place corrosion in surrounding; Coating can intercept CO in the air effectively simultaneously
2, O
2Deng SO in invasion and the soil
2- 4Etc. the corrosion of objectionable impurities, therefore, the present invention is to gaining everything and lose nothing to concrete.
5, because the present invention is raw materials used nontoxic, tasteless, pollution-free, therefore, compliance with environmental protection requirements of the present invention.
6, through test, just formed effective coating when the present invention uses within two hours, mechanical property is good, does not influence the back process engineering and is connected.
7, the present invention saves money: every square meter only needs the maintenance costs of several maos.
