Preparation process of self-cleaning surface of stainless steel power distribution cabinet

Abstract

The invention provides a preparation process of a self-cleaning surface of a stainless steel power distribution cabinet, and belongs to the technical field of metal surface treatment and modificationthereof. The process comprises the following steps of polishing a stainless steel substrate by using abrasive paper to remove an oxide film on the surface of the stainless steel substrate; then usingdeionized water and acetone for cleaning the surface of the stainless steel substrate, and then carrying out sand blasting coarsening treatment to obtain the stainless steel substrate with the rough surface; and then, modifying by adopting a low-surface-energy material, and drying to finally obtain the stainless steel super-hydrophobic surface. The invention solves the problems that the surface ofthe stainless steel is easy to corrode and generate scratches, and the prior art that utilizes an ultrashort pulse laser preparation method has higher process requirement, high precision requirementand high equipment cost and is difficult to realize large-scale production. The super-hydrophobic surface prepared by the method can enable the surface of the power distribution cabinet to have excellent antifouling performance and abrasion resistance, and the preparation process has the advantages of environmental protection, safety, simplicity in operation, high deposition rate, controllable cost, industrialization and great advantages and application prospects.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment and modification thereof, in particular to a preparation process for a self-cleaning surface of a stainless steel electric cabinet. Background technique [0002] Stainless steel is widely used in industrial production and life due to its smooth surface, high plasticity, toughness and mechanical strength, corrosion resistance to acids, alkaline gases, solutions and other media. Most of the stainless steel plates currently on the market have smooth surfaces, which are easily corroded by strong acids and alkalis in the air. After they are made into products, they will be affected by impacts or scratches. There are traces on the surface of the board, which affects the quality of the product and also affects the visual effect. [0003] Existing super-hydrophobic interface materials have special hydrophobic properties, can be used for surface self-cleaning, and the surface is wear-resis...
