The invention discloses a reinforcing agent for pervious concrete, and relates to the technical field of building auxiliary agents. The reinforcing agent is prepared from the following components in parts by weight: 30 to 50 parts of sodium lignin sulfonate, 30 to 40 parts of polyurethane emulsion, 10 to 20 parts of polyoxyethylene ether, 8 to 16 parts of triethanolamine, 5 to 12 parts of dodecyl acrylate, 5 to 8 parts of sodium dodecyl benzene sulfonate and 2 to 5 parts of coupling agent. The preparation method comprises the following steps: mixing the coupling agent, the sodium lignin sulfonate, the polyoxyethylene ether and the sodium dodecyl benzene sulfonate for the first time, then adding the polyurethane emulsion, the triethanolamine and the dodecyl acrylate for mixing for the second time, and keeping the temperature at 40 DEG C after mixing for the second time. All raw material components of the concrete are optimally configured, particularly the polyurethane emulsion, the polyoxyethylene ether, the triethanolamine and the dodecyl acrylate are introduced, and tests show that the water permeability of the concrete can be effectively improved.
本发明公开了一种透水混凝土用增强剂，涉及建筑用辅助剂技术领域。其中增强剂，以重量份计，包括以下组分：木质素磺酸钠：30份‑50份，聚氨酯乳液：30份‑40份，聚氧乙烯醚：10份‑20份，三乙醇胺：8份‑16份，十二烷基丙烯酸酯：5份‑12份，十二烷基苯磺酸钠：5份‑8份，偶联剂：2份‑5份；其制备方法如下：先将偶联剂、木质素磺酸钠、聚氧乙烯醚、十二烷基苯磺酸钠进行第一次混合，然后加入聚氨酯乳液、三乙醇胺、十二烷基丙烯酸酯进行第二次混合，第二次混合后保持温度为40℃，即可。对混凝土的各原料组分进行了优化配置，尤其是引入了聚氨酯乳液、聚氧乙烯醚、三乙醇胺及十二烷基丙烯酸酯，经测试，可以有效提升混凝土的透水性能。
