Preparation method of modified basalt fiber for expansion fiber anti-crack waterproof agent
The invention relates to a preparation method of a modified basalt fiber for an expansion fiber anti-crack waterproof agent, wherein the preparation method comprises the following steps: S01, firstly melting sepiolite and basalt, and then cooling and drawing basalt fibers; S02, adding a silane coupling agent into an ethanol solution to obtain a coupling agent solution with the mass fraction of 2%; S03, soaking the basalt fibers in the coupling agent solution; S04, after the basalt fibers are dispersed in the coupling agent solution, pouring the obtained solution into a container, putting the whole solution into a water bath device, and heating for 1 h at the constant temperature of 80 DEG C; and S05, taking out short fibers, and drying to obtain the modified basalt fibers. The preparation method has the beneficial effects that after a certain amount of sepiolite is added into basalt and is melted at high temperature, the basalt can be melted with the sepiolite, and a chemical reaction is carried out, so that the modified basalt with a new net-shaped structure is formed. The chemical durability, the flexibility, the heat-resistant strength and the like of the basalt fibers are remarkably improved.
本发明涉及一种膨胀纤维抗裂防水剂用改性玄武岩纤维的制备方法，包括如下步骤：S01、将海泡石和玄武岩先熔化，再降温拉制玄武岩纤维；S02、将硅烷偶联剂加入乙醇溶液中，得到质量分数为2％的偶联剂溶液；S03、将玄武岩纤维浸泡于偶联剂溶液内；S04、待玄武岩纤维分散于偶联剂溶液内后，将所得溶液倒入容器中，并将其整体放入水浴装置中，于80℃恒温条件下加热1h；S05、取出短纤维，干燥，得到改性玄武岩纤维。本发明的有益效果为：通过玄武岩中添加一定量海泡石高温熔化后，玄武岩能与海泡石相熔，并发生化学反应，形成新网状结构的改性玄武岩。使玄武岩纤维的化学耐久性、柔韧性、耐热强度等均有显著提高。
