Chinese patent (application number: 201610396879.5, publication number: CN105999769A) reported ZrOCl 2 ·8H 2 O with hydrofluoric acid and C 6 h 5 PO(OH) 2 Prepare zirconium phenylphosphonate reaction liquid, place it in a polytetrafluoroethylene liner reactor with copper mesh, and react under certain conditions to obtain an oil-water separation mesh. The raw materials used in this method are toxic and highly corrosive. Preparation Harsh conditions limit the breadth of its application
Chinese patent (Application No.: 201410603941.4, Publication No.: CN105617718A) reported that acid chloride solution modified metal porous material-dopamine precursor, and prepared superhydrophobic metal mesh. During the preparation process, the pH value should be strictly controlled between 8 and 10. The cycle is long, the process is cumbersome and consumes energy, which is not suitable for large-scale industrial production
Although the material exhibits good hydrophobic properties, its surface is not wear-resistant due to its poor mechanical properties, which limits its market application.

Abstract

The invention discloses a preparation method and application of a corrosion-resistant super-hydrophobic stainless steel mesh. The oil-water separation mesh uses stainless steel mesh as a base material, and adopts a resin bonding method to firmly bond modified fly ash to the base On the material skeleton, corrosion-resistant super-hydrophobic stainless steel mesh is obtained after curing. The corrosion-resistant stainless steel mesh of the present invention still maintains high superhydrophobic durability after 100 wear tests. The corrosion-resistant stainless steel mesh of the present invention can be applied in the fields of separation of oil / water mixture and treatment of oily wastewater, and continuous oil-water separation can be realized by building a device, the treatment capacity of oil-water mixture is large, the operation is simple, and the separation effect is good. The corrosion-resistant oil-water separation stainless steel mesh of the present invention has a simple preparation process, the whole production cycle is as low as 5 hours, and the preparation raw materials are cheap and easy to obtain, and the environment is friendly, which is convenient for industrial large-scale batch production, and has high economic benefits and practical value.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a method for preparing a corrosion-resistant super-hydrophobic stainless steel mesh, and also relates to an application of the corrosion-resistant super-hydrophobic stainless steel mesh. Background technique [0002] In recent years, with the improvement of human living standards and industrial production levels, the discharge of oily wastewater has also increased year by year. According to statistics, the wastewater discharged from oil fields, refineries and petrochemical plants around the world contains about 300,000 tons of crude oil and its products; industrial waste engine oil and automobile waste oil total about 1.3 million tons. Therefore, the need for oil-water separation has become urgent, and the development of materials that can recycle these organic pollutants can avoid economic losses and environmental tragedies. [0003] At present, with th...
