Multifunctional solid type concrete super plasticizer, preparation method and application
The invention relates to a multifunctional solid type concrete super plasticizer, a preparation method and application, and belongs to the technical field of concrete admixtures. The multifunctional solid type concrete super plasticizer is formed by condensation polymerization of a monomer A, a monomer B, a monomer C and a monomer D, the weight-average molecular weight of the multifunctional solid type concrete super plasticizer is 10000 to 50000; the monomer A is an aromatic compound with a phosphonic acid or phosphorous acid group; the monomer B is an aromatic carboxylic ester compound with small molecular polyether; the monomer C is aryl long-chain polyether. The multifunctional solid type concrete super plasticizer can be used as a dispersant of a hydraulic cementing agent and/or a potential hydraulic cementing agent, is a concrete super plasticizer integrating water reduction, shrinkage reduction and slump loss resistance, is clean in production and high in production efficiency, and can reduce the transportation cost and improve the cost performance of a product.
本发明涉及一种多功能固体型混凝土超塑化剂、制备方法及应用，属于混凝土外加剂技术领域。所述多功能固体型混凝土超塑化剂由单体A、单体B、单体C以及单体D缩聚而成；所述多功能固体型混凝土超塑化剂的重均分子量为10000‑50000；所述单体A为带膦酸或亚膦酸基团的芳香类化合物；所述单体B为带小分子聚醚的芳香羧酸酯类化合物；所述单体C为芳香基长链聚醚。所述多功能固体型混凝土超塑化剂可用作水硬性胶结剂和/或潜在水硬性胶结剂的分散剂，是集减水、减缩和保坍于一体的混凝土超塑化剂，该混凝土超塑化剂生产清洁，生产效率高，能降低运输成本，提高产品的性价比。
