Polycarboxylate superplasticizer as well as preparation method and application thereof
The invention relates to a polycarboxylate superplasticizer which comprises a structural unit A derived from polyoxyethylene ether monomers, a structural unit B derived from allyl phosphate monomers,a structural unit C derived from acrylic monomers and a structural unit D derived from styrene monomers, and the number ratio of the structural unit A to the structural unit B is 1: (2-15). The polycarboxylate superplasticizer is formed by polymerizing specific monomers according to a certain ratio, the setting time can be effectively shortened on the basis of a certain water reducing rate, gypsumis endowed with good mechanical performance and bonding performance, meanwhile, the process technology is simple and convenient, and the production process is free of pollution.
本发明涉及一种聚羧酸减水剂，包括衍生自聚氧乙烯醚单体的结构单元A、衍生自烯丙基磷酸酯类单体的结构单元B、衍生自丙烯酸类单体的结构单元C以及衍生自苯乙烯类单体的结构单元D，其中所述结构单元A和B的数量比为1:(2‑15)，所述聚羧酸减水剂采用特定的单体与配比聚合而成，具有一定减水率的基础上能够有效减少凝结时间，赋予石膏好的机械性能和粘接性能，同时工艺技术简便，生产过程无污染。
