Concrete surface anti-carbonization curing agent, preparation method and application thereof
The invention provides a concrete surface anti-carbonization curing agent, a preparation method and application thereof. The concrete surface anti-carbonization curing agent comprises the following raw materials in parts by weight: 150 to 230 parts of alpha-methacrylic acid, 190 to 240 parts of sodium thiocyanate, 70 to 90 parts of acrylic emulsion, 2 to 4 parts of 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate, 170 to 190 parts of nano silicon dioxide, 35 to 45 parts of nano montmorillonite powder, 1 to 3 parts of hydroxypropyl methyl cellulose, 1 to 3 parts of industrial ethanol and 195 to 206 parts of water. According to the invention, after the curing agent is sprayed on the surface of concrete, a thin compact nano-film can be quickly formed on the surface, so that the evaporation speed of water on the surface of the concrete can be remarkably reduced in a dry and windy severe environment; and the curing agent contains the anti-carbonization component and the permeation component, so that under the synergistic effect of the anti-carbonization component and the permeation component, the curing agent can effectively act on the concrete surface, and the carbonization depth of the concrete surface is obviously reduced.
本发明提供了一种混凝土表面抗碳化养护剂及其制备方法和应用，该混凝土表面抗碳化养护剂，以重量份计，包括以下原料：α‑甲基丙烯酸150～230份、硫氰酸钠190～240份、丙烯酸乳液70～90份、十二碳醇酯2～4份、纳米二氧化硅170～190份、纳米蒙脱石粉35～45份、羟丙基甲基纤维素1～3份、工业乙醇1～3份、水195～206份。本发明提供的养护剂喷涂在混凝土表面，能够快速在表面形成一薄层致密的纳米薄膜，在干燥、大风的恶劣环境中，能够显著降低混凝土表面水分的蒸发速度。同时，养护剂中含有抗碳化组分和渗透组分，在二者协同作用下，能够有效作用于混凝土表面，明显降低混凝土表面的碳化深度。
