The invention relates to a concrete surface reinforcing agent as well as a preparation method and application thereof, and the concrete surface reinforcing agent comprises the following raw materials in percentage by mass: 15%-24% of organic silicon resin, 12%-35% of filling powder, 2%-5% of latex powder, 4%-8% of sodium sulfate, 0.3%-3% of an additive and 30%-56% of water, the filling powder is formed by mixing modified titanium dioxide powder with a core-shell structure and modified kenaf fiber powder according to the mass ratio of 1: (0.8-1.5); the modified titanium dioxide powder takes titanium dioxide powder as a core and coumarone resin as a core shell, and the core shell has a porous structure. The concrete surface reinforcing agent is prepared by using the filling powder instead of organic silicon resin, and the concrete surface treated by the concrete surface reinforcing agent is better in compression resistance compared with the untreated concrete surface, and also has a good anti-permeation effect, a good anti-carbonization effect and a good anti-freezing effect.
本发明涉及一种混凝土表面增强剂及其制备方法和应用，所述混凝土表面增强剂包括以下质量百分比的原料：有机硅树脂15％‑24％、填充粉末12％‑35％、乳胶粉2％‑5％、硫酸钠4％‑8％、外加剂0.3％‑3％、水30％‑56％，所述填充粉末为具有核壳结构的改性二氧化钛粉末与改性葛麻纤维粉末按照质量比1:(0.8‑1.5)混合而成；所述改性二氧化钛粉末为以二氧化钛粉末为核芯，以古马隆树脂为核壳，核壳上具有多孔状结构。本发明通过利用填充粉末代替有机硅树脂制备获得混凝土表面增强剂，经该混凝土表面增强剂处理后的混凝土表面较未经处理的混凝土表面，其抗压能力更好，也具有良好的抗渗透效果、抗碳化效果，且还具有良好的抗冻效果。
