Antibacterial wear-resistant paint spraying method for grain machinery

Abstract

The invention discloses an antibacterial wear-resistant paint spraying method for grain machinery. The method comprises: dissolving citric acid monohydrate in a deionized water-ethanol solution, dropwisely adding into a nanometer zinc oxide suspension liquid, magnetically stirring in an oil bath, washing with ethanol, centrifuging, and carrying out vacuum drying to obtain surface-modified nanometer zinc oxide; adding polyether sulfone into N,N-dimethylacetamide, and magnetically stirring and dissolving to obtain a polyether sulfone solution; adding chopped carbon fibers into N,N-dimethylacetamide, mechanically stirring, pouring a polyethersulfone solution, mechanically stirring, pouring into ethanol, carrying out suction filtration, washing with absolute alcohol, and drying to obtain polyethersulfone-coated carbon fibers; adding silane-modified nanometer titanium dioxide, the obtained surface-modified nanometer zinc oxide and the polyethersulfone-coated carbon fibers into pure water, ultrasonically dispersing uniformly, adding into an aqueous fluorocarbon coating material, stirring uniformly, and performing ultrasonic treatment to obtain an antibacterial wear-resistant paint; and uniformly spraying the surface of a grain machine with the obtained antibacterial wear-resistant paint, standing, and drying by hot air.

Description

technical field [0001] The invention belongs to the field of paint spraying, and in particular relates to a paint spraying method for antibacterial and wear-resistant grain machinery. Background technique [0002] Abrasion, as a common failure mode of metal materials, not only shortens the service life of metal parts, but also causes waste of resources and energy, and brings immeasurable national economic losses. Therefore, it is of great significance to improve the wear resistance of metal materials. Focus on the friction and wear performance of grain machinery. Mechanical paint, also known as mechanical paint, refers to the paint coated on the surface of machinery and various machine parts. It is mainly used for surface decoration and protection of machine tools, equipment, automobiles, hardware, and glass fiber reinforced plastics. [0003] Nano-zinc oxide is an effective bactericidal material, and it shows better enhancement properties to polymers. In order to prepare a...
