Abstract

The invention provides a functional polyacrylic ester. The functional polyacrylic ester is polyacrylic ester modified by using salicylic aldehyde and quaternary ammonium salt. The salicylic aldehyde and the quaternary ammonium salt are two sterilizing and bacteria-resisting substances of different mechanisms, have sterilizing and bacteria-resisting synergic actions, can be used for effectively reducing the medicament resistance of bacteria microorganisms, are taken as film forming substances of an ocean anti-pollution coating, and can be used for chelating and adsorbing copper ions or nickel ions in seawater to generate novel sterilizing and bacteria-resisting effects. A method for preparing the functional polyacrylic ester provided by the invention is easy and practical, and the raw material source is rich.

Description

technical field [0001] The invention relates to a functional polyacrylate, in particular to a polyacrylate modified by salicylaldehyde and a quaternary ammonium salt, which is used as a film-forming substance for marine antifouling paint and belongs to the field of functional materials. technical background [0002] For many centuries, people have been exploring and researching anti-biofouling technologies and methods for marine vessels and marine facilities in seawater. At present, the most effective way is coating. The so-called anti-fouling principle of coating is the self-purification effect of low surface energy of the coating, so that marine organisms have no adhesion on the surface of the coating; the second is to add biocidal antibacterial and antifouling agents to the coating. Adding biocidal, antibacterial and antifouling agents is a widely used, simple and low-cost method for applying antifouling coatings. The traditional biocidal, antibacterial and antifouling a...
