Waste carbon fiber reinforced full-length prestress resin anchoring agent and preparation method thereof
The invention discloses a waste carbon fiber reinforced full-length prestress resin anchoring agent and a preparation method thereof, and relates to the field of reinforced supporting materials, an in-situ polymerization method is adopted, waste carbon fibers are added into an unsaturated polyester resin system to prepare a carbon fiber/unsaturated polyester resin hybrid material, and good dispersion of the carbon fibers in a polymer is achieved. The molar ratio of the carbon fiber/unsaturated polyester resin hybrid material is as follows: waste carbon fiber, PET or phthalic anhydride saturated binary acid, fumaric acid or maleic anhydride, propylene glycol and neopentyl glycol is 0.1: 1: 1.1-1.5: 1.2-1.3: 1. The weight ratio of the resin mortar to the resin premix to the waste chopped fibers to the high-strength filler is 100: (2-10): (400-600). The waste carbon fiber reinforced full-length prestress resin anchoring agent can solve the problem of insufficient shearing strength of an anchoring material in full-length prestress anchoring under high ground pressure. The method is an economical, efficient and environment-friendly treatment method for the carbon fiber waste. The preparation method is simple and easy to operate, and the cost can be remarkably saved.
本发明公开了一种废旧碳纤维增强全长预应力树脂锚固剂及其制备方法，涉及加固支护材料领域，采用原位聚合方法，将废旧碳纤维添加到不饱和聚酯树脂体系制备了碳纤维/不饱和聚酯树脂杂化材料，实现碳纤维在聚合物中的良好分散。碳纤维/不饱和聚酯树脂杂化材料摩尔比例：废旧碳纤维、PET或邻苯二甲酸酐饱和二元酸、富马酸或顺酐、丙二醇、新戊二醇0.1：1：1.1‑1.5：1.2‑1.3:1。树脂胶泥重量比：树脂预混料、废旧短切纤维和高强填料100：2‑10：400‑600。本发明的废旧碳纤维增强全长预应力树脂锚固剂能解决高地压下全长预应力锚固中锚固材料剪切强度不足的问题。本发明是碳纤维废料经济、高效、环保的处理方法。本发明的制备方法简单、易操作，能显著节省成本。
