Organic-inorganic composite retarding and toughening agent for magnesium phosphate cement and use method of organic-inorganic composite retarding and toughening agent
The invention belongs to the technical field of magnesium phosphate cement-based retarders, and discloses an organic-inorganic composite retarding and toughening agent for magnesium phosphate cement and a use method of the organic-inorganic composite retarding and toughening agent. The organic-inorganic composite retarding and toughening agent comprises borax and a water-soluble organic additive; the additive is prepared from polyacrylamide and gamma-methacryloyloxy propyl trimethoxy silane; the mass ratio of the polyacrylamide to the gamma-methacryloxy propyl trimethoxy silane is 1 to (0.5 to 3); the mass ratio of the borax to the organic additive is (5-30): 1. The invention also discloses a use method of the organic-inorganic composite retarding and toughening agent. The retarding toughening agent effectively prolongs the setting time of magnesium phosphate cement, increases the fluidity of the magnesium phosphate cement, and improves the strength, toughness and crack resistance of the magnesium phosphate cement and materials thereof to a certain extent; and meanwhile, the long-term strength is not reduced. The retarding flexibilizer provided by the invention is used for magnesium phosphate cement.
本发明属于磷酸镁水泥基缓凝剂的技术领域，公开了一种用于磷酸镁水泥的有机‑无机复合缓凝增韧剂及其使用方法。所述有机‑无机复合缓凝增韧剂包括硼砂和水溶性有机外加剂；外加剂包括聚丙烯酰胺和γ‑甲基丙烯酰氧基丙基三甲氧基硅烷；聚丙烯酰胺和γ‑甲基丙烯酰氧基丙基三甲氧基硅烷的质量比为1：(0.5～3)；硼砂和有机外加剂的质量比为(5～30)：1。本发明还公开了有机‑无机复合缓凝增韧剂的使用方法。本发明的缓凝增韧剂有效延长磷酸镁水泥的凝结时间，增加其流动性，同时一定程度上提高磷酸镁水泥及其材料的强度、韧性和抗裂性能；同时使长期强度不发生退缩。本发明的缓凝增韧剂用于磷酸镁水泥。
