3with the micro crystal of part ettringite, the little cavity in fill concrete, this process can the generation of acceleration of hydration gel of calcium silicate thing, thus has and improve the early strength of concrete surface and the effect of later strength; Emulsifying agent has hydrophilic and oleophylic two parts, containing surface-active material, the interfacial tension between liquid can be reduced, immiscible liquid is made to be easy to emulsification, when it is dispersed in dispersate surperficial, forms film or electrostatic double layer, disperse phase can be made with electric charge, the small droplets of disperse phase so just can be stoped to condense mutually, make the emulsion of formation more stable; Dispersant A and dispersant B can solid particulates unchangeably in dispersion liquid.
The preparation method of concrete abrasion-resistant enhancement type curing agent of the present invention is: wherein, and the preparation process of inorganic curing agent is: membrane-forming agent A, dispersant A, moisture adsorbent A, toughener and solvent orange 2 A are put into stainless steel cup, stirs; In the preparation process of organic curing agent: membrane-forming agent B, dispersant B and solvent B pour in beaker, after stirring, then pour moisture adsorbent B and emulsifying agent into, then stir, then organic curing agent and inorganic curing agent are mixed in proportion, obtain described concrete abrasion-resistant enhancement type curing agent.
What should be noted that in preparation process has: 1, this curing agent is made up of inorganic curing agent and organic curing agent two kinds of components, wherein the whole process for preparation of inorganic part is an endothermic process, a large amount of heat can be absorbed, so load weighted each component is put in stainless steel cup when preparing, use glass stick uniform stirring, instead of in beaker stirring and dissolving, otherwise beaker can be frozen broken; 2) described concrete abrasion-resistant enhancement type curing agent is emulsion liquid, close with the color of concrete itself, therefore will note carrying out mark when brushing, and notes identifying, in order to avoid the generation of holiday, recoat phenomenon; 3) to after onsite concrete or mortar Troweling press finishing, adopt painting way to be coated with curing agent during surperficial water stain-free, but will control uniformity coefficient well, and make every effort to even, must not drain spray; In order to ensure maintenance quality, be advisable to spray two times, require that second time sprinkling becomes vertical direction with first pass; 4) described concrete abrasion-resistant enhancement type curing agent is according to certain ratio and fixing spraying order composition, is non-concentrated type curing agent, is please rocked respectively by two kinds of curing agents before use evenly and re-use, and forbids thin up in use; 6) concrete abrasion-resistant enhancement type curing agent of the present invention has larger water-soluble, should not spray, but meet rain after curing agent film forming, then can not affect maintenance effect when rainy.
The constructional method of described concrete abrasion-resistant enhancement type curing agent is: with round brush by the brushing of concrete abrasion-resistant enhancement type curing agent on concrete surface, when brushing, brushing personnel reply has been coated with swiped through region and has marked, brush in order, push ahead successively.Brushing the first layer when concrete initial set, (summer about 0.5h, winter about 2h) brushing second layer after the brushing liquid film forming of the first layer, and the brushing direction of twice should be vertical, ensure the homogeneity of brushing, and the brushing order of the different curing agent of two kinds of functions can not be put upside down, first brushing can strengthen the inorganic curing agent of surface hardness, and have organic curing agent of health effect in brushing, brushing dosage is 0.22kg/m
2~ 0.23kg/m
2, its detected result is as shown in table 1:
