Abstract
The present invention provides a kind of reinforced concrete surface preservative, it is made up of the raw material of following weight part: silica flour 20-40 part, talcum powder 1-2 part, silica powder (174 ��m) 2-4 part, formaldehyde 10-20 part, emulsifying agent Aerosol? A-1022-3 part etc., favorable anti-corrosion effect of the present invention and easy to use.
Description
Technical field
The present invention relates to a kind of reinforced concrete surface preservative and its preparation method, belong to chemical technology field.
Background technology
Concrete antiseptic agent is a kind of completely new product that a new generation prevents steel reinforced concrete erosion, it breaches the traditional idea of Steel Concrete protection against corrosion, start use admixture rot-resistant novel method, fundamentally solve many deficiencies and the limitation of tradition anti-corrosion method. Use sulfate corrosion-resistance preservative for concrete that concrete can be made to have the good performances such as the erosion of anti-salt ion, freeze-thaw-circulation destruction and high resistance infiltration. Concrete structure is not only required anticorrosion but also requires impervious engineering by particularly suitable. Mixing this product can also make concrete shrinkage value reduce, and is convenient to mass concrete construction. Concrete antiseptic agent application is easy, it may not be necessary to special construction technique. This kind of anti-corrosion method has also fully utilized industrial waste flyash simultaneously, has the meaning of environmental protection.
Summary of the invention
Goal of the invention: it is an object of the invention to provide the reinforced concrete surface preservative of a kind of successful and its preparation method.
Technical scheme: it is an object of the invention to by following scheme realize:
A kind of reinforced concrete surface preservative, it is made up of the raw material of following weight part: silica flour 20-40 part, talcum powder 1-2 part, silica powder (174 ��m) 2-4 part, Sodium Silicofluoride 4-8 part, magnesium fluoride 3-5 part, ventilation breather 4-8 part, potassium pyrophosphate 6-10 part, trisodium phosphate 4-8 part, zinc sulfate 2-4 part, ferrous sulfate 3-5 part, Sodium hexametaphosphate 99 4-8 part, POTASSIUM BOROHYDRIDE 2-4 part, borax 4-8 part, potassium sorbate 6-10 part, Witco 1298 Soft Acid 4-8 part, ammonium nitrate 4-8 part, saltpetre 4-8 part, formaldehyde 10-20 part, emulsifying agent AerosolA-1022-3 part, emulsifying agent Dowfax2A12-3 part, diethanolamine 5-10 part, sodium bicarbonate 1-2 part, lauryl mercaptan 2-3 part, NaOH0.5-1 part, dimethylbenzene 140-160 part.
The preparation method of described reinforced concrete surface preservative, comprises the following steps: take dimethylbenzene by formula rate, adds other materials, stirs 30-40min, to obtain final product.
Useful effect:
The present invention carries out modification by raw material, it is to increase depth of penetration, reduces water-intake rate, extends salt-fog resistant time and ageing-resistant time, and preservative effect is obvious, and easy to use.
Embodiment
Form by the following examples, the foregoing of the present invention is described in further detail again, but this should not being interpreted as, the scope of the above-mentioned theme of the present invention is only limitted to following example, and all technology realized based on foregoing of the present invention all belong to the scope of the present invention.
Embodiment 1: get silica flour 20 parts, talcum powder 2 parts, silica powder (174 ��m) 2 parts, Sodium Silicofluoride 8 parts, magnesium fluoride 3 parts, ventilation breather 8 parts, potassium pyrophosphate 6 parts, trisodium phosphate 8 parts, 2 parts, zinc sulfate, 5 parts, ferrous sulfate, Sodium hexametaphosphate 99 4 parts, POTASSIUM BOROHYDRIDE 4 parts, borax 4 parts, potassium sorbate 10 parts, Witco 1298 Soft Acid 4 parts, 4 parts, ammonium nitrate, 8 parts, saltpetre, 10 parts, formaldehyde, emulsifying agent AerosolA-1023 part, emulsifying agent Dowfax2A13 part, diethanolamine 5 parts, sodium bicarbonate 2 parts, lauryl mercaptan 2 parts, NaOH1 part, dimethylbenzene 140 parts, preparation method comprises the following steps: take dimethylbenzene by formula rate, add other materials, stir 30min, obtain.
The salient features of the reinforced concrete surface preservative that the present embodiment is obtained is such as following table.
| Sequence number | Project | The present invention | Ordinary reinforced concrete surface preservative |
| 1 | Depth of penetration | 4.5mm | 2.3mm |
| 2 | Water-intake rate | 0.3% | 1% |
| 3 | Salt spray resistance is tested | It is greater than 1800 hours | Lower than 1000 hours |
| 4 | Ageing-resistant experiment | It is greater than 2000 hours | Lower than 800 hours |
Illustrate that reinforced concrete surface preservative of the present invention has excellent antiseptic property, it may also be useful to effective and convenient.
