Polycarboxylic acid additive with high slump loss resistance and preparation process thereof
The invention discloses a polycarboxylic acid additive with high slump loss resistance, which is prepared from the following raw materials in parts by weight: 300-400 parts of monomer, 200-400 parts of water, 1-10 parts of ammonium persulfate, 1-3 parts of ferrous iron, 1-10 parts of sodium hypophosphite, a material A and a material B. The material A comprises 10-50 parts of acid, 7-15 parts of ethylene glycol, 1-10 parts of glyceride and 10-100 parts of water, and the material B comprises 1-6 parts of VC, 10-100 parts of water and 100-200 parts of replenishing water. After the ethylene glycol is added into the additive, the workability and the slump retaining property of the additive are obviously improved, so that the stability of the working performance of the concrete is ensured, the problem that the slump of the concrete is relatively high is avoided, and the quality of the concrete is ensured.
本发明公开了一种高保坍性聚羧酸添加剂，由下述重量份的原料制备而成：单体300‑400份、水200‑400份、过铵1‑10份、亚铁1‑3份、次磷酸钠1‑10份、A料与B料，所述A料包括酸10‑50份、乙二醇7‑15份，甘油酯1‑10份与水10‑100份，所述B料包括VC1‑6份、水10‑100份与补水100‑200份。本申请通过在添加剂中添加有乙二醇后，添加剂的和易性和保坍性上有一个明显的提升，去保证混凝土工作性能的稳定性，避免了混凝土坍落度较快的问题，保证了混凝土的质量。
