Problems solved by technology

A method for manufacturing and constructing nano-coatings is disclosed. The method uses ultrasonic dispersion, but only ultrasonic technology is used, and nano-slurry is not prepared separately. The uniform wrapping effect of modified substances on the surface of nano-materials is not good. And no constant temperature device is used, prone to severe local reactions

Abstract

The invention relates to a preparation device and method of nanoparticle functional slurry. The preparation device comprises a reactor and a mixing shaft, a supersonic generator is arranged in the reactor, the exterior of the reactor is provided with a metering pump, a material outlet of the metering pump directly faces to the reactor, the preparation device also comprises an ampere-voltage meter, a measurement device of the ampere-voltage meter stretches into the reactor, and the preparation device also comprises a thermostat. Through stirring rotation rate and ultrasonic frequency design, nano-material dispersibility is effectively improved. Control of the nanoparticle functional slurry is effectively improved so that effects of uniformly coating the surfaces of the nanoparticles with the modification substance are obtained. Through a constant-temperature water bath, a violent local reaction is avoided in the slurry. Through observation of the ampere-voltage meter value, photovoltaic conversion effects can be visually identified.

Description

technical field [0001] The invention relates to functional slurry equipment, in particular to nanoparticle functional slurry equipment and a method for preparing nanoparticle functional slurry for fluorocarbon coatings using the device. Background technique [0002] Nanomaterials modified coatings are technically difficult, but the application effect is good. Due to the strong electronegativity and high polarity of fluorine atoms, the copolymers synthesized from fluorine monomers have a large crystallization tendency, and it is difficult to solve the key technology of compatibility between nanomaterials and organic solvents for fluorocarbon coatings. Therefore, the research and development focus at home and abroad is currently Mainly focus on the fields of water-based fluorocarbon coatings and powder fluorocarbon coatings. There are also a few companies that use other nano-materials to modify fluorocarbon coatings, but they have not been successful; especially in terms of l...
