Abstract

The invention discloses a method for preparing an anti-icing zinc oxide coating on a copper surface, and the adhesion between the zinc oxide and the copper sheet is enhanced by dopamine hydrochloride. Zinc oxide on the surface of the copper sheet is fluorinated to increase its contact angle and rolling angle, and prolong the freezing time. The present invention adopts hydrothermal method, first prepares zinc oxide solution with sol-gel method, adds dopamine hydrochloride, prepares zinc oxide seed layer on the surface of copper sheet, after sintering at a certain temperature, hydrothermal method, control certain temperature, time, in After sintering at a certain temperature, it is treated with low surface energy substances and its surface static contact angle and freezing time are measured. The invention has the advantages of low production cost, simple preparation method, low requirements on reaction equipment, mild reaction conditions, no environmental pollution and large-scale production.

Description

technical field [0001] The invention relates to a method for preparing an anti-icing zinc oxide coating, in particular to a method for preparing an anti-icing zinc oxide coating on a copper surface. Background technique [0002] In nature, icing is a beautiful natural landscape that can bring visual enjoyment to human beings, but it also often causes inconvenience and even disasters to people's daily life and practical engineering. For example, in the power system, the bare aluminum conductors of high-voltage overhead transmission will be covered with ice in a certain atmospheric environment. When the transmission wire is seriously iced, disasters such as line tripping, wire galloping, line breakage, transmission tower collapse, insulator flashover, and communication interruption will occur. Icing on different parts of the aircraft surface will lead to poor aerodynamic performance, violent vibration of the aircraft, obstructing the pilot's sight, interfering with communicat...
