Low-cost polycarboxylate superplasticizer for concrete and preparation process of low-cost polycarboxylate superplasticizer
The invention discloses a low-cost polycarboxylate superplasticizer for concrete. The low-cost polycarboxylate superplasticizer is specifically prepared from the following components in parts by weight: 310-330 parts of a monomer, 20-30 parts of acrylic acid, 5-10 parts of a neutralizer, 300-500 parts of deionized water, 80-115 parts of a material A, 75-120 parts of a material B and 3-5 parts of an initiator, the material A comprises 30-45 parts of acrylic acid and 50-70 parts of deionized water; and the material B comprises 5-10 parts of phosphorus-based polyester and 70-110 parts of deionized water. The invention discloses a preparation process of the phosphorus-based polyester. The invention belongs to the technical field of water reducing agents for concrete, and particularly provides a low-cost polycarboxylic acid water reducing agent for concrete and a preparation process of the low-cost polycarboxylic acid water reducing agent.
本发明公开了一种低成本混凝土用聚羧酸减水剂，具体包括下列重量份数的组分：单体310‑330份、丙烯酸20‑30份、中和剂5‑10份、去离子水300‑500份、A物料80‑115份、B物料75‑120份和引发剂3‑5份；A物料包括丙烯酸30‑45份和去离子水50‑70份；B物料包括磷基多元脂5‑10份和去离子水70‑110份，并公开了其制备工艺。本发明属于混凝土用减水剂技术领域，具体提供了一种低成本混凝土用聚羧酸减水剂及其制备工艺。
