Viscosity reduction type polycarboxylic acid high-performance water reducing agent mother liquor for wind power mixing tower concrete and preparation method of viscosity reduction type polycarboxylic acid high-performance water reducing agent mother liquor
The invention discloses a viscosity reduction type polycarboxylic acid high-performance water reducing agent mother liquor for wind power mixing tower concrete and a preparation method thereof.The viscosity reduction type polycarboxylic acid high-performance water reducing agent mother liquor is prepared from, by mass, a base material, a dripping material A and a dripping material B. The base material comprises 30%-40% of methyl allyl polyoxyethylene ether, 0.005%-0.015% of butyl acrylate, 0.1%-1.2% of an initiator and 40%-62% of purified water, the dropping material A comprises 3%-4.5% of acrylic acid and 3%-4.5% of purified water, and the dropping material B comprises 0.005%-0.01% of a reducing agent, 0.1%-0.3% of a chain transfer agent and 5%-10% of purified water. The polycarboxylate superplasticizer has a high water-reducing rate, can maintain better workability and fluidity, is beneficial for improving the construction efficiency, and well solves the problem of difficult construction when a traditional polycarboxylate superplasticizer is used for producing high-grade premixed concrete of a mixing tower.
本发明公开了一种用于风电混塔砼的降粘型聚羧酸高性能减水剂母液及其制备方法，按照质量百分比计，降粘型聚羧酸高性能减水剂母液包括底料、滴加料A和滴加料B，其中，底料包括甲基烯丙基聚氧乙烯醚30％～40％、丙烯酸丁酯0.005％～0.015％、引发剂0.1％～1.2％和纯净水40％～62％，滴加料A包括丙烯酸3％～4.5％和纯净水3％～4.5％，滴加料B包括还原剂0.005％～0.01％、链转移剂0.1％～0.3％和纯净水5％～10％。本发明具有较高的减水率，能够保持更好的和易性和流动性，有利于提高施工效率，很好地解决了传统聚羧酸减水剂在生产混塔高标号预拌混凝土时所存在的施工困难方面的问题。
