High-performance adhesive impregnated carbon fiber and curing method thereof
The invention belongs to the field of buildings, and discloses a high-performance adhesive impregnated carbon fiber and a curing method thereof.The adhesive is composed of 100 parts by mass of water glass, 50-100 parts by mass of a concrete interface treating agent and 1-2 parts by mass of a defoaming agent, the carbon fiber is impregnated into the adhesive and maintained for 10 min, the carbon fiber is taken out and then straightened and fixed, the curing time is not shorter than 3 days within the temperature range of 5-25 DEG C, and the curing time is not shorter than 3 days within the temperature range of 5-25 DEG C. The curing time is not less than 2 days when the temperature is higher than 25 DEG C. The high-performance glue has good water resistance, alkali resistance and high temperature resistance after being cured, so that after the carbon fiber bundle impregnated by the glue is cured, the mechanical property of the carbon fiber bundle can still be kept unchanged even if the carbon fiber bundle is soaked in clear water or an alkaline solution or in a high-temperature environment.
本发明属于建筑领域，本发明公开一种高性能胶粘剂浸渍碳纤维及其固化方法，该胶粘剂由100质量份的水玻璃、50～100质量份的混凝土界面处理剂、1～2质量份的消泡剂组成，将碳纤维浸渍到胶粘剂中，维持10min，取出后拉直并固定，5～25℃范围内固化时间不小于3天，高于25℃时固化时间不小于2天。该高性能胶固化后具有良好的耐水、耐碱、耐高温性能，因此，采用该胶浸渍的碳纤维束固化后，即使经历清水或碱性溶液浸泡，或在高温环境中，仍能保持其力学性能不变。
