Abstract

The invention discloses a fluorine-free polyphenylene sulfide super-hydrophobic coating. The fluorine free polyphenylene sulfide super-hydrophobic coating is characterized by being prepared from the following raw materials in parts by weight: 70-95 parts of polyphenylene sulfide resin, 5-30 parts of silicone resin, 0.1-10 parts of nano sheet particles, 0.5-10 parts of nano fibers, 0.1-3 parts of cysteine, 200-500 parts of ethanol, 10-30 parts of water and 10-30 parts of a surfactant. The invention also discloses a method of preparing the fluorine-free polyphenylene sulfide super-hydrophobic coating. The coating solves the problems that an existing polyphenylene sulfide super-hydrophobic coating needs the addition of fluorine-containing substances and the wear resistance of the existing polyphenylene sulfide super-hydrophobic coating is insufficient.

Description

technical field [0001] The invention relates to a polyphenylene sulfide superhydrophobic coating and a preparation method thereof. Background technique [0002] In recent years, polyphenylene sulfide resin has been identified as one of my country's strategic new materials because of its high mechanical strength, high temperature resistance, strong chemical resistance, strong adhesion, and flame retardancy. Often used in electrical and electronic, machinery, construction, coatings and other fields. [0003] Although polyphenylene sulfide resin is often used as a base for traditional coatings, it is rarely used as a base for functional coatings. Although the existing literature [doi] 10.1016 / j.jallcom.2017.05.333 and [doi] 10.1166 / jnn.2012.6585 etc. use polyphenylene sulfide as the superhydrophobic coating film-forming material, but because of the hydrophobicity of polyphenylene sulfide itself Not good, the hydrophobic angle is only 78°, so it is usually necessary to add flu...
