Problems solved by technology

However, as a long-term transportation pipeline, there should be no microbial growth and growth on the material as much as possible. This patent only considers the application of enhanced materials in terms of strength and toughness, and does not consider the microbial adsorption growth caused by the environment where the material is used.

Abstract

The invention belongs to the field of coating chemical industry, and concretely discloses a hydrophobic and oleophobic antibacterial coating. The coating is prepared by mixing 95-99 wt% of acrylatedepoxidized soybean oil, 0.05-2 wt% of ethyl lauroyl arginate hydrochloride and 1-3 wt% of an initiator. The coating has an ultraviolet curing characteristics; a coating layer formed by the coating hasan excellent antibacterial property on the basis of maintaining the original hardness and stability, and the surface of the coating layer has super-hydrophobic and oleophobic properties, so the anti-pollution performance is greatly enhanced; and the coating is suitable for daily maintenance of various pipelines, and is especially suitable for bacteriostatic and clean maintenance of the inner walls of the pipelines immersed in a water environment for a long term.

Description

technical field [0001] The invention relates to the field of paint chemical industry, more specifically, to a hydrophobic and oleophobic antibacterial paint and its application. Background technique [0002] PVC pipe (PVC-U pipe) rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It is the earliest plastic pipe that has been developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture. PVC pipe is used in applications for drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. In practical applications, the eutrophic environment in the industrial environment increases the possibility of the growth of microorganisms and bacteria. The reproduction of bacteria will affect the quality and transportation of the liquid in the pipeline. purity decreases. [0003] Patent CN...
