Modified plastic copper-plated steel fiber as well as preparation method and application thereof
The invention discloses a modified plastic copper-plated steel fiber as well as a preparation method and application thereof, and belongs to the field of mineral inorganic materials. The modified plastic copper-plated steel fiber is prepared by the following method: plating copper on the steel fiber; then the copper-plated steel fibers are subjected to structural shaping, so that the middle parts of the copper-plated steel fibers are wavy, and the two ends of the copper-plated steel fibers are forked; and soaking the molded copper-plated steel fiber in a phosphoric acid solution, and after soaking is finished, drying the molded copper-plated steel fiber to obtain the modified molded copper-plated steel fiber. After copper plating, structure shaping and phosphoric acid surface modification treatment, the bonding performance between the steel fibers and the UHPC is remarkably improved, and therefore the consistency and stability of the bone holding force of the steel fibers are improved. Meanwhile, the treatment method is simple and easy to operate, time and cost are saved, and production efficiency is improved.
本发明公开了一种改性塑形镀铜钢纤维、其制备方法及应用，属于矿用无机材料领域。本发明的改性塑形镀铜钢纤维，由如下方法制备而成：对钢纤维进行镀铜；然后将镀铜钢纤维进行结构塑形，使其中间部分呈波浪型，两端呈分叉状；然后将塑形镀铜钢纤维置于磷酸溶液中浸泡，待浸泡结束后，烘干，获得改性塑形镀铜钢纤维。经镀铜、结构塑形和磷酸表面改性处理后，钢纤维与UHPC混凝土之间的粘结性能得到显著改善，从而提高了钢纤维握骨力的一致性和稳定性。同时，本发明的处理方法简单易于操作，节省时间和成本，提高生产效率。
