Abstract

The invention discloses a metal surface treatment agent for a gelatinous film. The surfaces of acrylate adhesive solution particles in the metal surface treatment agent contain a large amount of carboxyls; aniline is added into the acrylate adhesive solution; aniline monomers diffuse to the inside of a micelle first, and are then doped with the carboxyls; subsequently, under the action of an oxidant, the aniline generates a polymerization reaction on the surfaces of emulsion particles, so that a contact angle of a polyaniline coating to water is increased, and the adhesive force and the water resistance are improved; according to the coating, the surface of metal is passivated to form a protecting action under the actions of electron transfer and oxidation reduction; an inorganic component Ti<4+> introduced by silanization-modified hexafluorotitanic acid forms TiO2 particles in a heating and curing process, and the TiO2 particles are uniformly filled in the gaps of a silane film, so that the whole film layer is more uniform and compact, a micro electrochemical reaction on the surface of the film layer can be effectively inhibited, and further the corrosion resistance is greatly improved.

Description

technical field [0001] The invention relates to a treatment agent, in particular to a gel-like film metal surface treatment agent and a preparation method thereof. Background technique [0002] Polyaniline is a kind of conductive polymer material with stable performance and environmental friendliness, and its oxidation-reduction potential is much higher than that of metal. Its coating can passivate the metal surface through electron transfer and redox in acidic or neutral medium. It has a protective effect and is a good material for metal anti-corrosion. However, polyaniline has strong molecular chain rigidity, is insoluble and infusible, and is difficult to process. It is usually used in combination with other film-forming substances. Acrylate resin is a commonly used film-forming substance, which has good film-forming properties and adhesion. [0003] At present, there are three ways to make polyaniline and acrylic resin composite films: polyaniline coating is coated with...
