Abstract
The invention discloses a method for preparing clear water concrete protectant, which comprises raw material mixing and a production process. The clear water concrete protectant prepared by the method has the characteristics of avoiding changing the color and appearance of a base layer, improving the durability of the clear water concrete, prolonging the service life of the clear water concrete, along with ultrahigh infiltrability, high breathability, high waterproof performance, high environmental friendliness, colorlessness and transparency. Compared with products of the same kind, the clear water concrete protectant has higher infiltrability, high fouling resistance and high alkali resistance.
Description
Affiliated technical field
The present invention relates to the protectant production technology category of clear-water concrete.
Background technology
Clear-water concrete claims decorative concrete again, the one-time-concreting moulding, do not do any outer decoration, therefore the surface effect that directly adopts onsite concrete is different from normal concrete as facing, its surfacing is smooth, color and luster is even, and corner angle are clearly demarcated, and it not only has honesty, sedate naturally outward appearance charm, softness, firm, warm, cold and detached sensation can be given, and the building emotion can be expressed.At present, be widely used as the decorative plate of outer wall of buildings, bridge pier and the also clear-water concretes that adopt of bridge construction such as high-speed railway, viaduct more, as Capital Airport T3 terminal exterior wall cladding, the Beijing-Shanghai High-Speed Railway bridge pier.But the clear-water concrete protection is one of more formidable common quality defect in using always, and it directly has influence on the security and the weather resistance of clear-water concrete structure.
At present, market supernatant water concrete protective agent is to be main film forming base-material with the pure silicon resin, adds pigment and the formulated aqueous semi-transparent liquid product of various auxiliary agent, and this series products has certain waterproofing protection effect.But this product water-repellancy, perviousness and polluting proofing property are relatively poor.
Summary of the invention
Purpose of the present invention is exactly to prepare a kind of clear-water concrete protective material with higher water-repellancy, perviousness and contamination resistance.
Realize that the protectant concrete grammar of clear-water concrete of the present invention is:
The at first selected protectant raw material of clear-water concrete of the present invention is also pressed following prescription (weight %) preparation:
Deionized water 60-65;
Silicone resin emulsion 27-32;
Silicone additives 6-10;
Methyl siliconic acid potassium 0.3-0.8;
Silicone antifoam agent 0.2-0.4;
Isothiazoline sanitas 0.1-0.3.
After proportioning raw materials is selected, carry out concrete production technique:
At first deionized water is joined in the stirring tank, start stirrer, add silicone resin emulsion, silicone additives, methyl siliconic acid potassium and silicone antifoam agent then successively, stirred 20-40 minute, add the stirring of isothiazoline sanitas at last and got final product discharging in 10-20 minute.
The present invention is that employing type siloxane silicone material is a base-material; be equipped with the aqueous transparent liquid product that multiple auxiliary agent is prepared from; being used for clear-water concrete set of surfaces concrete surface protecting is all over the body with repairing decoration; can repair the various flaws on clear-water concrete surface, can keep a kind of new high-tech product of concrete true qualities and quality again.Its superpower penetrating power, high ventilation " breathing " function, excellent water resistance, the splendid feature of environmental protection, water white transparency, the color that does not change basic unit and outward appearance, the prevention damage that to be some media of carrier with water suffer to close with water to the erosion of clear-water concrete, the weather resistance that improves clear-water concrete, the work-ing life that prolongs clear-water concrete, protection clear-water concrete, prevent that mould, liver moss from producing, reduce weathering, the salt marsh and the accumulation of salt in the surface soil, avoiding polluting and keep clean.
The performance of clear-water concrete protective material of the present invention and existing like product is as shown in table 1:
Table 1
| Performance | Standard-required | Clear-water concrete protective material of the present invention | Existing like product |
| The water-intake rate ratio, % | ≤20 | 17 | 23 |
| Perviousness | 2mm, anhydrous mark does not have variable color | 0mm, anhydrous mark does not have variable color | 1mm has the water mark that variable color is arranged |
| Resistance to soiling, % | ≤20 | 12 | 25 |
| Alkali resistance | 48h is no abnormal | 48h is no abnormal | The 48h light discolouration |
Clear-water concrete protective material of the present invention has been compared following advantage with existing like product:
One, belong to aqueous product, asepsis environment-protecting, the construction odorlessness is to environment and body harmless;
Two, superpower penetrating power, high ventilation " breathing " function has IMAGE;
Three, paint film water white transparency, the color that does not change clear-water concrete and outward appearance;
Four, You Yi water resistance and anti-fouling performance.
By the table in as seen, clear-water concrete protective material of the present invention has better perviousness, resistance to soiling and alkali resistance than existing like product.
Embodiment
Realize that the protectant embodiment of clear-water concrete of the present invention is:
The at first selected protectant raw material of clear-water concrete of the present invention is also pressed following prescription (weight %) preparation:

Silicone additives 8;
Methyl siliconic acid potassium 0.5;
Silicone antifoam agent 0.3;
Isothiazoline sanitas 0.2.
After proportioning raw materials is selected, carry out concrete production technique:
At first deionized water is joined in the stirring tank, start stirrer, add silicone resin emulsion, silicone additives, methyl siliconic acid potassium and silicone antifoam agent then successively, stirred 30 minutes, add the stirring of isothiazoline sanitas at last and got final product discharging in 15 minutes.
