Bending-resistant corrosion-resistant composite material electric pole and preparation method thereof
The invention discloses a bending-resistant and corrosion-resistant composite material electric pole. The invention discloses a preparation method of the electric pole, which comprises the following steps: adding the glass fiber into a nitric acid solution, carrying out ultrasonic treatment at 30-40 DEG C for 10-30 minutes at the ultrasonic frequency of 5-15 kHz, filtering, washing a filter cake, carrying out vacuum drying, adding the polyethyleneimine, the catalyst and the water, carrying out ultrasonic treatment at 60-80 DEG C for 1-5 hours, and filtering to obtain the composite glass fiber; the preparation method comprises the following steps: uniformly mixing aromatic polyurethane resin, polyether polyol and styrene, and immersing composite glass fibers into the mixture to obtain a prepreg a; uniformly mixing aliphatic polyurethane resin, polyether polyol and styrene, and immersing composite glass fibers into the mixture to obtain a prepreg b; the rod-shaped mold is heated, demolding wax is smeared on the outer side of the rod-shaped mold, and the dipping material a is wound from the root to the top of the rod-shaped mold; then winding the impregnated material b from the root to the top of the rod-shaped mold; and curing the wound rod-shaped mold at high pressure for 5-10 hours, and demolding.
本发明公开了一种抗弯曲耐腐蚀复合材料电杆。本发明公开了上述电杆制备方法，将玻璃纤维加入至硝酸溶液中，30‑40℃超声10‑30min，超声频率为5‑15kHz，过滤，洗涤滤饼，真空干燥，加入聚乙烯亚胺、催化剂、水，60‑80℃超声1‑5h，过滤得到复合玻璃纤维；将芳香族聚氨酯树脂、聚醚多元醇、苯乙烯混合均匀，再将复合玻璃纤维浸入其中，得到预浸料a；将脂肪族聚氨酯树脂、聚醚多元醇、苯乙烯混合均匀，再将复合玻璃纤维浸入其中，得到预浸料b；加热杆状模具，在杆状模具外侧涂抹脱模蜡，将浸渍料a从杆状模具的根部向顶部缠绕；然后将浸渍料b从杆状模具的根部向顶部缠绕；将缠绕后杆状模具高压固化5‑10h，脱模。
