Environment-friendly concrete high-efficiency water-reducing retarding plastic retaining agent and preparation method thereof
The invention discloses an environment-friendly concrete high-efficiency water-reducing retarding plastic retaining agent. The environment-friendly concrete high-efficiency water-reducing retarding plastic retaining agent is characterized in comprising the following components in parts by weight: 15-20 parts of a polymeric seleninic acid/N, N-bis (2-hydroxyethyl)-2-aminoethanesulfonic acid modified quaternary ammonium salt-15/2-methacryloyloxyethyl choline phosphate/4-trimethyl phosphobutyrate copolymer, 3, to 5 parts of 3-chloro boronic acid modified N-(trimethoxysilane propyl) ethanediaminetriacetate sodium, 1-3 parts of humic acid, 0.5-1.5 parts of beryllium chloride, 1-2 parts of zinc hydroxide and 30-40 parts of water. The invention also discloses a preparation method of the environment-friendly concrete high-efficiency water-reducing retarding plasticity retaining agent. The environment-friendly concrete high-efficiency water-reducing retarding plasticity retaining agent disclosed by the invention combines the advantages of a water reducing agent, a retarding agent and a plasticity-maintaining agent; the environment-friendly concrete high-efficiency water-reducing retardingplasticity retaining agent is good in comprehensive performance, low in air entraining amount, high in water reducing rate, remarkable in retarding and plastic retaining effect, safe and environment-friendly to use, and capable of effectively improving the flowability and workability of concrete, remarkably improving the pumping construction performance of the concrete and improving the strengthand durability of the concrete.
本发明公开了一种环保型混凝土高效减水缓凝保塑剂，其特征在于，包括如下重量份计的各组分：聚合型亚硒酸/N,N‑双(2‑羟乙基)‑2‑氨基乙磺酸改性季铵盐‑15/2‑甲基丙烯酰氧乙基磷酸胆碱/4‑磷丁酸三甲酯共聚物15‑20份、3‑氯甲基苯硼酸改性N‑(三甲氧基硅丙基)乙二胺三乙酸钠盐3‑5份、腐殖酸1‑3份、氯化铍0.5‑1.5份、氢氧化锌1‑2份、水30‑40份。本发明还公开了所述环保型混凝土高效减水缓凝保塑剂的制备方法。本发明公开的环保型混凝土高效减水缓凝保塑剂结合了减水剂、缓凝剂和保塑剂的优点，综合性能佳、引气量低、减水率高、缓凝保塑效果显著，使用安全环保，能够有效提高混凝土的流动性和工作性，显著改善混凝土的泵送施工性能，提高混凝土的强度和耐久性。
