Problems solved by technology

At present, many studies on super-amphiphobic coatings can be recognized internationally, but super-amphiphobic coatings have not achieved large-scale industrial production. The reason is that there are still some basic problems in the production of super-amphiphobic coatings: ① In terms of performance: When the super-amphiphobic coating is put into use, it is easy to form a gap with the interface, causing problems such as coating oxidation ...

Abstract

The invention discloses a device and method for producing super-amphiphobic paint with modification of modified particles. The device comprises a super-amphiphobic paint component A production system and a super-amphiphobic paint component B production system. The super-amphiphobic paint component A production system comprises a first subsystem and a second subsystem. The first subsystem comprises a modified particle high-speed dispersing machine, a modified particle six-kettle parallel reaction device and a cyclone hydraulic separator. The second subsystem comprises a resin monomer raw material premixer, a fluorine-containing hydroxy-acrylic resin six-kettle series reaction device and a resin solvent preheater. The super-amphiphobic paint component B production system comprises a fluorine-containing PU prepolymer curing agent double-kettle series reaction device, a prepolymer raw material stirrer and a prepolymer raw material preheater. The device is capable of achieving consecutive production, convenient to maintain and good in achievability, and a process adopted in the method is simple.

Description

technical field [0001] The invention relates to the field of super-amphiphobic coatings, in particular to a device and method for producing super-amphiphobic coatings modified by modified particles. Background technique [0002] Due to its hydrophobic and oleophobic properties, super-amphiphobic coatings have broad application prospects in daily life and national production, especially the environmentally friendly double-layer coatings prepared by mixing surface-treated silica micro-nano particles and fluorine-containing resins. Component super-amphiphobic coating, its self-cleaning, anti-corrosion, anti-freezing and waxing, anti-adhesion and other functions make it widely used in the life and production of building materials, oil pipelines, glass ceramics, textile leather, electronic products, kitchen and bathroom utensils, etc. There are a wide range of applications. [0003] In recent years, many researchers and teams have conducted research on the production of super-am...
