Abstract

The invention discloses a high-adhesion polyaniline anticorrosive coating. The anticorrosive coating comprises, by weight parts, 42-60 parts of acrylic resin, 16-27 parts of cyanate ester, 12-20 parts of urethane acrylate, 6-13 parts of polyaniline powder, 5-11 parts of brucite powder, 3-9 parts of camphorsulfonic acid, 3-10 parts of glyceryl tristearate, 4-8 parts of sodium cocoyl isethionate, 2-7 parts of zinc dioleate, 1-6 parts of citric acid, 1-5 parts of maleic anhydride grafted polypropylene, 2-5 parts of titanium dioxide, 1-3 parts of fibrous wollastonite powder, 3-9 parts of coupling agent, 36-55 parts of organic solvent and 3-9 parts of deionized water. The invention further discloses a method for preparing the anticorrosive coating. The anticorrosive coating is good in adhesion and anticorrosive functions and salt resistance and has good comprehensive performance. Moreover, the preparation method is simple, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of paint materials, in particular to a polyaniline anticorrosion paint with high adhesion and a preparation method thereof. Background technique [0002] As we all know, polyaniline is a conductive polymer, which not only has high electrical conductivity, but also has the advantages of low raw material cost, good environmental stability, easy preparation, high yield, and corrosion resistance. Polyaniline is widely used in coatings, absorbing materials, batteries and conductive fibers and other fields. [0003] In the field of coating applications, although polyaniline has excellent anti-corrosion properties, its bonding strength with metal materials is weak, and its utilization rate is low. In addition, its machinability and compatibility with resins are also poor. The use of polyaniline in the field of anti-corrosion coatings is limited. Contents of the invention [0004] The technical problem to be solved is: in...
