Preparation method of concrete forming curing agent
The invention discloses a preparation method of a concrete forming curing agent, the preparation method comprises the following steps: preparing modified powder by using a grinding device, and uniformly stirring the modified powder, polyethylene glycol, vinyl trimethoxy silane, sodium silicate, hydroxymethyl cellulose, aluminum chloride and water to obtain the concrete forming curing agent. The concrete forming curing agent can quickly form a covering film on the surface of concrete to prevent water evaporation of the concrete so that sufficient hydration is ensured, the autotrophication purpose is achieved, and the modified powder in the concrete forming curing agent increases the impermeability of the concrete and effectively prevents the saltpetering phenomenon; the superfine powder prepared by the grinding device is more easily acidified by concentrated sulfuric acid, the acidification effect is good, the dispersing performance and the adsorption performance of the modified powder are further improved, and the prepared concrete forming curing agent is good in curing effect.
本发明公开了一种混凝土成型养护剂的制备方法，该制备方法中通过使用粉磨装置制备改性粉体，然后将改性粉体、聚乙二醇、乙烯基三甲氧基硅烷、硅酸钠、羟甲基纤维素、氯化铝以及水搅拌均匀，得到该混凝土成型养护剂，该混凝土成型养护剂可以在混凝土表面迅速形成覆盖薄膜，阻止混凝土水份蒸发，从而保证充分水化，达到自养的目的，而且该混凝土成型养护剂中的改性粉体增加了混凝土的抗渗性能，有效防止了泛碱现象的产生；该粉磨装置制备得到的超细粉体更易被浓硫酸酸化且酸化效果好，进一步的提高了改性粉体的分散性能和吸附性能，使得制备的混凝土成型养护剂的养护效果好。
