Preparation method of aluminum-based power transmission line with anti-icing coating layer

The invention relates to a nanometer coating material, and provides a preparation method of an aluminum-based power transmission line with an anti-icing coating layer. The anti-icing coating layer prepared by a hydrolysis method has a static water contact angle greater than 150 degrees; after the anti-icing coating layer is applied to an aluminum sheet, the icing time can be obviously delayed, andthe icing area can be reduced; when the common aluminum sheet is completely covered with ice after 10 h, the icing area of the coating layer is only 60%; after being abraded, the coating layer stillhas certain anti-icing property; after the anti-icing coating layer is applied to the aluminum wire, the ice removal ability is obviously reduced. 本发明涉及纳米涂层材料，提供种具有防覆冰涂层的铝基输电线路的制备方法。本发明通过水解法制备出的防覆冰涂层具有大于150°的静态水接触角，应用在铝片上面不仅能够明显延缓结冰时间，而且能够减少覆冰面积，当10h后普通铝片达到全覆冰时，涂层覆冰面积仅为60%。在进行磨损之后仍具有定的防覆冰性能。此外，应用到铝线能够还能明显降低脱冰力。
