Description
Technical field
The present invention relates to additives for building materials technical field, refer to a kind of curing compound and preparation method thereof especially.
Background technology
Concrete needs large quantity of moisture in hydration process, lack moisture will delay even to stop hydration process, originally certain moisture is there is in concrete mix, its mixing water is even greater than the moisture needed for hydrated cementitious, but owing to there is a large amount of capillary porosity ducts in concrete, moisture more easily runs off, the evaporation of moisture simultaneously and the water suction of basic unit also make the moisture in concrete lose fast, therefore, carrying out smoothly of concrete hydrating process be ensured, moisture-keeping maintaining must be carried out to it.
Curing compound, also known as concrete curing liquid, is a kind of class coating material, can form closed film, make concrete surface and air exclusion when it is sprayed at concrete surface, significantly reduces moisture from concrete surface drain evaporation.Thus utilize the moisture of self in concrete to complete hydration to greatest extent, reach the object of maintenance.
Conventional concrete curing agent film forming speed is slow, and needs first to heat and could use under the environment that temperature is lower, and practicality is poor.
In addition, curing compound can be divided into water glass type and emulsion-type two kinds by the kind of its main film forming substance, and water glass type curing agent and hydrolysis product of cement react and generate ettringite colloidal film; Emulsion-type curing agent then forms one deck oil film by being coated in concrete surface.The curing agent of this two type all can stop the evaporation of moisture in concrete, wherein emulsion-type curing agent effect is better than water glass type curing agent, emulsion-type curing agent water retention is generally about 70%, the water retention of water glass type curing agent is about 20%, how to improve curing agent water retention further and becomes problem in the urgent need to address.
