Graphene oxide modified slump retaining mother liquor and preparation method and use method thereof
The invention belongs to the field of auxiliary agents of building materials, and relates to a graphene oxide modified slump retaining mother liquor which is prepared from the following ingredients in parts by weight: 20 to 60 parts of graphene oxide dispersion liquid, 300 to 360 parts of isopentenol polyoxyethylene ether, 2.5 to 3 parts of hydrogen peroxide, 38 to 40 parts of acrylic acid, 50 to 55 parts of hydroxyethyl acrylate, 1.2 to 1.5 parts of ascorbic acid, 2 to 2.5 parts of thiohydracrylic acid and 25 to 35 parts of sodium hydroxide. Graphene oxide is introduced into the graphene oxide modified slump-retaining mother liquor so that the slump-retaining performance of the slump-retaining mother liquor is improved on the premise that the sensitivity of the slump-retaining mother liquor is not increased. Meanwhile, the invention also provides a preparation method and a use method of the graphene oxide modified slump retaining mother liquor.
本发明属于建筑材料的辅助剂类领域，一种氧化石墨烯改性保坍母液，包含以下重量份的成分：20‑60份氧化石墨烯分散液、300‑360份异戊烯醇聚氧乙烯醚、2.5‑3份双氧水、38‑40份丙烯酸、50‑55份丙烯酸羟乙酯、1.2‑1.5份抗坏血酸、2‑2.5份巯基丙酸、25‑35份氢氧化钠。本氧化石墨烯改性保坍母液引入了氧化石墨烯，在保持保坍母液敏感性不上升的前提下提升了保坍母液的保坍性能。同时本发明还提出一种氧化石墨烯改性保坍母液的制备方和使用方法。
