High-strength self-leveling grouting material
The invention relates to a high-strength self-leveling grouting material which comprises a compound component of etherified cellulose and a modified polycarboxylate superplasticizer, and the etherified cellulose is a product obtained after cellulose is etherified by an etherifying agent; the modified polycarboxylate superplasticizer is a quaternary copolymer, and monomers of the quaternary copolymer are unsaturated polyether, unsaturated carboxylic acid, unsaturated sulfonate and polyol acrylate respectively. When the unsaturated polyether, the unsaturated carboxylic acid, the unsaturated sulfonate and the polyol acrylate are copolymerized according to a certain ratio, the obtained modified polycarboxylate superplasticizer is compounded with the etherified cellulose, and the obtained grouting material formula can have good bending strength and compressive strength and ideal flowing performance and expansion performance.
本发明涉及一种高强度自流平灌浆料，所述高强度自流平灌浆料包括醚化纤维素和改性聚羧酸减水剂的复配成分，其中醚化纤维素是纤维素经醚化剂醚化后的产物；改性聚羧酸减水剂为四元共聚聚合物，所述四元共聚聚合物的单体分别为不饱和聚醚、不饱和羧酸、不饱和磺酸盐以及多元醇丙烯酸酯。当不饱和聚醚、不饱和羧酸、不饱和磺酸盐和多元醇丙烯酸酯以一定配比共聚，所得到的改性聚羧酸减水剂与醚化纤维素复配后，所得灌浆料配方可以兼有良好的抗折抗压的强度，以及较为理想的流动性能和膨胀性能。
