Binary composite fiber reinforced epoxy resin-based rapid repair material and preparation method thereof
The invention relates to the technical field of repairing materials, and discloses a binary composite fiber reinforced epoxy resin-based rapid repairing material and a preparation method thereof, and the binary composite fiber reinforced epoxy resin-based rapid repairing material comprises the following raw materials by mass: 259.85 g of epoxy resin, 89.36 g of a curing agent, 25.99 g of a diluent, 24.22 g of a flexibilizer, 1200 g of fine aggregate, 259.85 g of a filler, 1.04 g of an antifoaming agent, 0.78-2.34 g of basalt fiber, and 15.59-31.18 g of calcium sulfate whisker. According to the basalt fiber-calcium sulfate whisker binary composite fiber reinforced epoxy resin-based rapid repair material and the preparation method thereof, the basalt fiber with a relatively large size and the calcium sulfate whisker with a relatively small size are mixed and doped; a large number of freely-distributed fibers can restrain propagation of microcracks in different areas and in different scales in a repairing material matrix, the defects that a conventional epoxy resin-based repairing material is poor in early performance, large in brittleness, insufficient in toughness and the like are effectively overcome, and matching of early high strength and high toughness of the epoxy resin-based repairing material is achieved.
本发明涉及修补材料技术领域，且公开了一种二元复合纤维增强环氧树脂基快速修复材料及其制备方法，包括以下质量比例的原料：环氧树脂259.85g、固化剂89.36g、稀释剂25.99g、增韧剂24.22g、细骨料1200g、填料259.85g、消泡剂1.04g、玄武岩纤维0.78～2.34g、硫酸钙晶须15.59～31.18g。本发明在玄武岩纤维‑硫酸钙晶须二元复合纤维增强环氧树脂基快速修复材料及其制备方法中，尺度较大的玄武岩纤维和尺度较小的硫酸钙晶须混杂掺入，大量自由分布的纤维可以约束修补材料基体内部不同区域以及不同尺度的微裂缝扩展，有效改善了常规的环氧树脂基修补材料早期性能较差、脆性大、韧性不足等缺陷，实现了环氧树脂基修补材料早期高强度与高韧性的匹配。
