Environment-friendly composite early-strength water reducing agent and preparation method thereof
The invention discloses an environment-friendly composite early-strength water reducing agent, which is characterized by including the following components in parts by weight: 15 to 20 parts of 3-(1-naphthyl) acrylic acid/3-[N, N-dimethyl-[2-(2-methylprop-2-enoyloxy) ethyl] ammonium] propane-1-sulfonic acid inner salt/4-vinyl-2, 3-dihydrobenzofuran/alliin copolymer; 4 to 8 parts of hyperbranched polylysine; 2-5 parts of sodium alginate; 4 to 7 parts of celestite; 1-3 parts of spar; 1 to 3 parts of N-(3-triethoxysilylpropyl) glucosamide; and 30-40 parts of water. The invention also discloses apreparation method of the environment-friendly composite early strength water reducing agent. The environment-friendly composite early-strength water reducing agent disclosed by the invention is remarkable in early-strength water reducing effect, small in mixing amount, capable of effectively improving the compressive strength of concrete, reducing the shrinkage rate of the concrete and shorteningthe production period of the concrete, free of obvious negative effects on the comprehensive performance of the concrete, and green and environment-friendly in preparation and use processes.
本发明公开了一种环保型复合早强减水剂，其特征在于，包括如下重量份计的各组分：3‑(1‑萘基)丙烯酸/3‑[N,N‑二甲基‑[2‑(2‑甲基丙‑2‑烯酰氧基)乙基]铵]丙烷‑1‑磺酸内盐/4‑乙烯基‑2,3‑二氢苯并呋喃/蒜氨酸共聚物15‑20份、超支化聚赖氨酸4‑8份、海藻酸钠2‑5份、天青石4‑7份、似晶石1‑3份、N‑(3‑三乙氧硅基丙基)葡糖酰胺1‑3份、水30‑40份。本发明还公开了所述环保型复合早强减水剂的制备方法。本发明公开的环保型复合早强减水剂早强减水效果显著，掺量少，能有效改善混凝土的抗压强度、降低其收缩率、缩短其生产周期，对混凝土综合性能无明显负面影响，制备和使用过程中绿色环保。
