Polyformaldehyde fiber sizing agent for concrete as well as preparation method and application of polyformaldehyde fiber sizing agent
The invention provides a polyformaldehyde fiber sizing agent for concrete. The polyformaldehyde fiber sizing agent is prepared from the following components in percentage by mass: 1.00 to 15.00 percent of polyethyleneimine, 2.00 to 30.00 percent of a polyurethane emulsion film-forming agent, 0.50 to 1.50 percent of a coupling agent, 0.01 to 2.00 percent of a pH value regulator and 51.50 to 97.49 percent of deionized water. The sizing agent disclosed by the invention can be used for carrying out surface modification on polyformaldehyde fibers and enhancing interface bonding between the fibers and concrete. The preparation method of the sizing agent is simple, easy to operate and suitable for large-scale industrial production, and meanwhile, the mechanical property of the modified polyformaldehyde fiber reinforced concrete is obviously improved. The invention also provides a preparation method and application of the polyformaldehyde fiber sizing agent for concrete.
本发明提供了一种混凝土用聚甲醛纤维上浆剂，包括以下质量百分比的成分：聚乙烯亚胺1.00～15.00％，聚氨酯乳液成膜剂2.00～30.00％，偶联剂0.50％～1.50％，PH值调节剂0.01～2.00％，去离子水51.50％～97.49％。本发明的上浆剂可以对聚甲醛纤维进行表面改性，并增强纤维与混凝土之间的界面结合。上浆剂的制备方法简单、操作容易，适合大规模工业化生产，同时改性后的聚甲醛纤维增强混凝土力学性能明显提高。本发明还提供了一种混凝土用聚甲醛纤维上浆剂的制备方法和应用。
