Polycarboxylate water reducer for lightweight concrete and preparation method thereof
The invention provides a polycarboxylate water reducer for lightweight concrete and a preparation method thereof. The polycarboxylate water reducer for lightweight concrete comprises 30-38% of macro-monomer, 0.2-0.5% of hydrogen peroxide, 2.8-4.8% of acrylic acid, 1.0-3.0% of a modifier, 0.10-0.20% of mercapto-propionic acid, 0.05-0.12% of vitamin C, 0.3-0.8% of a regulator, 0.07-0.1% of sodium hydroxide, and the balance being water. The dripping material is improved, so that mother liquor molecules wrap the cement particles more fully, the inclusion and homogenization effects on the cement particles with molecular repulsion are achieved, and the wrapping performance of the lightweight concrete adapts to the requirements of various materials.
本发明提供一种用于轻质混凝土的聚羧酸减水剂及其制备方法，该用于轻质混凝土的聚羧酸减水剂，以质量百分比计，包括30‑38％的大单体、0.2‑0.5％的双氧水、2.8‑4.8％的丙烯酸、1.0‑3.0％的改性剂、0.10‑0.20％的巯基丙酸、0.05‑0.12％的维生素C、0.3‑0.8％的调节剂、0.07‑0.1％的氢氧化钠，余量为水。本发明通过改善滴加料使母液分子对水泥颗粒的包裹更加充分，对分子排斥水泥颗粒起到包容和均匀的作用，使轻质混凝土的包裹性能适应各种材料的要求。
