Abstract

The invention provides a transformation method for high temperature resistance and superhydrophobic property of outdoor power equipment. The method comprises the following steps: 1) pretreatment: carrying out corona treatment on the surface of outdoor electric equipment to be sprayed to activate the surface and increase surface energy; 2) dilution: diluting a high-temperature-resistant super-hydrophobic nano-coating to be sprayed by the use of 0.1-0.2 times by weight of deionized water; and 3) spraying: spraying the diluted high-temperature-resistant super-hydrophobic nano-coating obtained in the step 2) onto the surface of the outdoor power equipment pretreated in the step 1), wherein pressure is 0.15-1.5 MPa; the distance from a spray gun to the surface of the base material is no less than 5 cm; and the included angle from the spray gun to the surface of the base is 70-90 degrees. By the transformation method, contact angle of water on the surface of the outdoor power equipment after coating is 161-175 degrees; roll angle is less than 8 degrees. It is ensured that the outdoor power equipment has strong hydrophobicity and has high temperature resistance, oil resistance and self-cleaning performance.

Description

technical field [0001] The invention relates to a method for modifying the super-hydrophobic performance of equipment, in particular to a method for modifying the high-temperature-resistant super-hydrophobic performance of outdoor power equipment. Background technique [0002] With the continuous rapid growth of my country's economy, the State Grid Corporation of my country, based on the basic national conditions of China's unbalanced energy distribution and productivity development, plans to build AC 1000 kV and DC ±800 kV UHV power grids in order to optimize the allocation of power resources in a wider range , to realize the efficient utilization of my country's limited energy resources. Because outdoor power equipment is responsible for long-distance power transmission, intermediate power transformation and transmission reserves, etc., it plays a mainstay role in the entire power system. However, since outdoor power equipment is exposed to light, rain and acid-base corros...
