Early-strength polycarboxylic acid high-performance water reducing agent and preparation process thereof
The invention discloses an early-strength polycarboxylic acid high-performance water reducing agent, which is prepared from the following raw materials in parts by weight: 330 to 350 parts of monomers, 400 to 600 parts of deionized water, 111.4 to 123.8 parts of a material A, 65 to 95 parts of a material B, 5 to 10 parts of an initiator and 3 to 5 parts of a neutralizer, the material A is prepared from 1 to 3 parts of thiohydracrylic acid, 0.4 to 0.8 part of VC (Vitamin C) and 110 to 120 parts of deionized water; the material B is prepared from 25 to 35 parts of acrylic acid and 40 to 60 parts of deionized water. The invention discloses a preparation process of the water-based paint. The invention belongs to the technical field of water reducing agents, and particularly provides an early-strength polycarboxylic acid high-performance water reducing agent and a preparation process thereof, the water reducing agent has the characteristics of high-pressure steam curing, low mixing amount, high water reducing rate, early strength and improvement of concrete toughness, and meets the production requirements of PHC pipe piles.
本发明公开了一种早强型聚羧酸高性能减水剂，包括下列重量份数的原料：单体330‑350份、去离子水400‑600份、A物料111.4‑123.8份、B物料65‑95份、引发剂5‑10份、中和剂3‑5份；所述A物料包括巯基丙酸1‑3份、VC0.4‑0.8份和去离子水110‑120份；所述B物料包括丙烯酸25‑35份和去离子水40‑60份，并公开了其制备工艺。本发明属于减水剂技术领域，具体提供了一种早强型聚羧酸高性能减水剂及其制备工艺，该减水剂具有高压蒸养、掺量低、高减水率、早强和提高混凝土韧性的特点，满足PHC管桩生产要求。
