[0037]The present application also relates to a preparation method of the concrete curing agent, the method comprising the following steps:
[0038] (1) Dissolve the stabilizer and the quick-hardening component in water respectively to form a stabilizer solution and a quick-hardening component solution for subsequent use;
[0039] (2) Add paraffin wax emulsion, defoamer, plasticizer, and film-forming aid into the reaction vessel at one time and stir evenly. Usually, the stirring time is about 1-2 minutes, and the stirring speed is controlled at 100-300r / min;
[0040] (3) Add the EVA emulsion and the silicone-modified acrylate emulsion into the reaction vessel in turn and stir, the stirring speed is controlled at 400-500r / min, after adding the two emulsions, continue to stir for 0.5-1min;
[0041] (4) The standby stabilizer solution and the quick-hardening component solution are added to the reaction vessel successively, and the remaining water (i.e., deduct the water in the st...
Embodiment 1
[0051] The curing agent used for early curing of cement concrete pavement in this embodiment is composed of the following components: 55 parts by mass of paraffin emulsion, 15 parts by mass of EVA emulsion, 5 parts by mass of silicone modified acrylate emulsion, 0.8 parts by mass of stabilizer, 0.06 parts by mass of foaming agent, 0.7 parts by mass of plasticizer, 0.8 parts by mass of film-forming aid, 0.5 parts by mass of rapid hardening component, and 22.14 parts by mass of water.
[0052] The stabilizer is composed of sodium dodecyl sulfonate, sodium trimetaphosphate and nano-silicon dioxide, wherein the weight ratio of sodium dodecyl sulfonate: sodium trimetaphosphate: nano-silicon dioxide=3:4:3. The rapid hardening component is composed of lithium carbonate and triethanolamine, and the weight ratio of lithium carbonate and triethanolamine is 1:3.
[0053] The preparation of the curing agent comprises the following steps: first, dissolve the weighed stabilizer and the quic...
