Multifunctional curing agent for concrete in low-temperature environment and preparation method of multifunctional curing agent
The invention discloses a multifunctional concrete curing agent in a low-temperature environment and a preparation method of the multifunctional concrete curing agent. The multifunctional concrete curing agent comprises 15%-30% of a permeation densification component, 15%-30% of an acrylic emulsion, 40%-68% of a paraffin emulsion and 0.5%-1% of a coalescing agent. The concrete densifying agent has two components of permeation densifying and organic film forming, and when the concrete densifying agent is uniformly distributed on the surface of concrete for curing in a construction mode of smearing or spraying and the like, the densifying component permeates into the concrete and continuously reacts with calcium ions in the concrete, so that the densifying effect is improved. Slightly-soluble or insoluble crystalline substances such as hydrated calcium silicate and ettringite which are insoluble in water are formed, capillary channels are blocked, and water evaporation channels are reduced. And the organic film-forming component is evaporated, and emulsion particles are gathered together to form a thin film with low moisture permeability on the surface of the concrete. The inorganic densification component and the organic film-forming component act together, so that the water retention effect of the concrete is improved.
本发明公开了一种低温环境下混凝土多功能养护剂及其制备方法，包括渗透增密组分15％～30％，丙烯酸乳液15％～30％，石蜡乳液40％～68％，成膜助剂0.5％～1％。本发明具有渗透增密以及有机成膜两种组分，将其采用涂抹或喷洒等施工方式均匀分布到混凝土表面进行养护时，增密组分渗入到混凝土内部，不断与混凝土内部的钙离子发生反应，形成不溶于水的水合硅酸钙和钙矾石类等微溶或不溶结晶物质，堵塞毛细孔道，减小水分蒸发的通道。有机成膜组分通过蒸发，乳液颗粒聚拢后在混凝土表面形成透湿性较小的薄膜。无机增密组分和有机成膜组分共同作用，提升混凝土的保水效果。
