Abstract

The invention discloses a preparation method of a titanium dioxide-polyaniline composite corrosion-resistant coating. According to the preparation method, the steps of preparing nanometer titanium dioxide, synthesizing titanium dioxide-polyaniline, coating the surface of a metal plate with the titanium dioxide-polyaniline, and the like are synchronously carried out in a hydrothermal reaction kettle, and are completed through one step. The technical problem in the prior art that nanometer titanium dioxide is easy to agglomerate in a mixed solution system comprising the nanometer titanium dioxide and polyaniline is solved well, the technological process is greatly shortened, and the process control difficulty is reduced; besides, the step of heating and drying the composite coating required in the prior art is eliminated, and a series of technical problems that a coating easily cracks due to organic matter volatilization to further influence the combination firmness between the composite coating and a metal matrix, and the like are solved. The preparation method has the characteristics of being short in technological process, simple to control, stable and reliable in product quality, and the like, and the titanium dioxide-polyaniline composite corrosion-resistant coating prepared is suitable for being used as cathodic protection of copper, steel or stainless steel base material.

Description

Technical field

[0001] The invention relates to a method for preparing a titanium dioxide-polyaniline composite coating, in particular to a method for preparing a titanium dioxide-polyaniline composite anticorrosive coating. Background technique

[0002] Titanium dioxide has a unique photoelectric conversion effect. The titanium dioxide is made into a coating and applied to the metal surface. Under light, the valence band electrons of titanium dioxide are excited to the conduction band to form electron-hole pairs, and the negative electrons enter the metal matrix to make the metal electrode The potential is reduced to the cathodic protection zone where corrosion does not occur, as a non-sacrificial photocathodic protection material, to achieve corrosion protection of metals. This corrosion protection ability depends on the photoelectric efficiency of titanium dioxide.

[0003] However, the photoelectric efficiency of pure titanium dioxide is low, and the protective effect of the a...
