Concrete early strength agent and preparation method thereof
The invention discloses a concrete early strength agent and a preparation method thereof. Comprising the following components in parts by weight: 5.50 to 12.50 parts of hyperbranched polyether containing phosphine end groups, 0.042 to 0.072 part of polyethylene glycol and carboxylic acid polycondensate, 0.036 to 0.047 part of unsaturated sulfonic acid monomer, 0.036 to 0.047 part of unsaturated amide monomer, 3.80 to 6.00 parts of unsaturated anhydride monomer, 5.50 to 13.00 parts of soluble calcium salt, 0.40 to 0.70 part of dispersing agent, a small amount of PH (Potential of Hydrogen) regulator, 0.06 to 0.20 part of initiator and 65.00 to 83.00 parts of water. The early strength of the concrete can be obviously improved, the water reducing effect is achieved, the synthesis process is not complex, the cost is low, the practicability is high, and the concrete early strength improver is suitable for wide popularization.
本发明公开了一种混凝土早强剂及其制备方法，包括以下组分制备：含膦端基超支化聚醚5.50‑12.50份、聚乙二醇而羧酸缩聚物0.042‑0.072份、不饱和磺酸类单体0.036‑0.047份、不饱和酰胺类单体0.036‑0.047份、不饱和酸酐类单体3.80‑6.00份、可溶性钙盐5.50‑13.00份、分散剂0.40‑0.70份、PH调节剂少量、引发剂0.06‑0.20份与水65.00‑83.00份，可以明显提高混凝土早期强度，并且兼有减水的作用，并且合成工艺不复杂，成本较低，实用性较强，适应于广泛推广。
