Concrete water reducer and preparation method thereof
The invention relates to a concrete water reducing agent which is prepared from the following components in parts by weight: 30 to 50 parts of starch, 100 to 150 parts of acrylamide, 50 to 80 parts of acrylic acid, 180 to 220 parts of isopentenyl polyoxyethylene ether, 30 to 40 parts of 30 percent hydrogen peroxide, 3 to 6 parts of ascorbic acid and 0.1 to 0.2 part of mercaptoethanol. The concrete water reducing agent is prepared through the steps of enzymolysis with amylase, gelatinization, raw material mixing, pH value adjustment, concentration and the like. The concrete water reducing agent has the characteristics of good water-retaining property, workability, expansibility and pressure resistance.
本发明涉及一种混凝土减水剂，包括以下重量份组分，淀粉30‑50份、丙烯酰胺100‑150份、丙烯酸50‑80份、异戊烯基聚氧乙烯醚(TPEG‑2400)180‑220份、30％过氧化氢30‑40份、抗坏血酸3‑6份、疏基乙醇0.1‑0.2份。通过淀粉酶解、糊化，原料混合、酸碱度调节、浓缩等步骤制备成混凝土减水剂。本发明中的混凝土减水剂具有保水性、和易性、扩展性及抗压性好的特点。
