Description
Technical field
The present invention relates to a kind of preparation method of curing compound.
Background technology
Concrete pouring is an important step of concrete construction, after concrete depositing, must carry out maintenance in the process of initial set, and namely keep necessary humidity and temperature, hydration reaction carries out to make it have suff water to ensure; Suitable maintenance can increase substantially the performances such as concrete weather resistance, intensity, wear resistance, volume stability.Traditional maintenance process litters a bag maintenance, plastics film maintenance and watering maintenance, and these methods are time-consuming, take a lot of work and serious waste water resources.Use the method for film forming curing agent curing concrete long-standing, but its maintenance effect cannot meet actual needs, film forming curing agent is as emulsion type concrete curing agent, mainly prepared by benzene emulsion, after benzene emulsion curing agent is sprayed at concrete surface, in atmosphere along with the volatilization of solvent in curing agent, form fine and close polymer curing film, thus hinder the evaporation of concrete surface moisture.But the surface bonding power of traditional benzene emulsion and green concrete humidity is poor, cause its Water-saving effect unsatisfactory, product performance are difficult to the requirement reaching practical application.
Patent CN102010230 provides a kind of preparation method of curing compound, use (methyl) acrylate, vinylbenzene and organic fluorine unsaturated monomer and/or organosilicon unsaturated monomer, macromolecule emulsion is obtained through letex polymerization, carry out composite with membrane-forming agent, softening agent, defoamer and water afterwards, obtain curing compound.This invent organic fluorine unsaturated monomer used and organosilicon unsaturated monomer expensive, cost is high; And the organic fluorine formed and organosilicon polymer hydrophobicity strong, be unfavorable for that curing agent is to the even coating at concrete surface of the wetting of green concrete surface and curing agent.
Patent CN102976652 provides a kind of preparation method of curing compound of high water retention, comprises the steps: vinylbenzene and acrylic ester monomer to be prepared as emulsion, in emulsion, drip initiator solution; Vinylbenzene, acrylic ester monomer, vinylformic acid and initiator are added drop-wise in reactant and are obtained by reacting polymer emulsion, then it is mixed with film coalescence aid, softening agent, defoamer, flow agent and water, obtain curing compound.This invention is traditional benzene emulsion, and the introducing of nucleocapsid structure can only reduce the minimum film-forming temperature of emulsion, fundamentally can not improve the curing film of formation to the restraining effect of green concrete surface-moisture.
Patent ZL02111497.8 provides a kind of water-base liquid film-type concrete curing agent, this curing agent is made up of acrylate polymer emulsion, wax emulsion, film coalescence aid, wetting agent, softening agent and flow agent, when being coated on concrete and the sand-cement slurry surface of initial set, form the colourless fluid-tight efficient curing film of continuous print, can penetrate into again in concrete pore simultaneously, sealed hair pore, prevents the generation of moisture evaporation and cement concrete surface excreting water phenomenon.This invention is the curing agent that acrylate polymer emulsion and wax latex composite compounding are formed, the composite not positive synergy of physical action, and the consistency of the two is bad.
Above-mentioned curing agent invention is all only considered from curing agent self, does not consider the keying action of curing agent and concrete surface.
