Concrete surface reinforcing agent as well as preparation method and application thereof
The invention discloses a concrete surface reinforcing agent as well as a preparation method and application thereof, and belongs to the technical field of building materials. The coating mainly comprises the following raw materials in percentage by weight: 10 to 25 weight percent of lithium-based penetrating fluid, 3 to 10 weight percent of organic silicon resin, 3 to 10 weight percent of epoxy resin emulsion, 2 to 5 weight percent of sodium sulfate, 2 to 5 weight percent of latex powder, 1 to 5 weight percent of modified microcrystalline cellulose, 1 to 5 weight percent of talcum powder, 0.1 to 1 weight percent of coalescing agent, 0.1 to 0.5 weight percent of defoaming agent and the balance of water. The concrete surface reinforcing agent provided by the invention is based on the lithium-based penetrating fluid, the organic silicon resin and the epoxy resin emulsion which are strong in adhesive force, convenient to cure, strong in chemical stability and high in self strength, and is externally doped with the sodium sulfate, the latex powder, the modified microcrystalline cellulose, the talcum powder, the coalescing agent and the defoaming agent; when being smeared on the concrete surface, the concrete surface modifier can effectively improve the pore structure of concrete, so that the microstructure of the concrete surface is more compact, the surface strength and durability of the concrete are improved, and potential safety hazards caused by cracks of the concrete are solved.
本发明公开了一种混凝土表面增强剂及其制备方法和应用，属于建筑材料技术领域。其主要包括以下重量比的原料：锂基渗透液10‑25wt％、有机硅树脂3‑10wt％、环氧树脂乳液3‑10wt％、硫酸钠2‑5wt％、乳胶粉2‑5wt％、改性微晶纤维素1‑5wt％、滑石粉1‑5wt％、成膜助剂0.1‑1wt％和消泡剂0.1‑0.5wt％，其余量为水。本发明提供的混凝土表面增强剂以具有附着力强、固化方便、化学稳定性强和自身强度高的锂基渗透液、有机硅树脂、环氧树脂乳液为基础，外掺硫酸钠、乳胶粉、改性微晶纤维素、滑石粉、成膜助剂和消泡剂，涂抹在混凝土表面能有效改善混凝土的孔结构，使混凝土表面的微观结构更加致密，提高混凝土的表面强度和耐久性，解决混凝土因出现裂缝导致的安全隐患。
