Problems solved by technology

Using the doping effect of the carboxyl group on the acrylate polymer chain to aniline, an acrylate-aniline copolymer was synthesized by in-situ polymerization; however, the research mainly focused on the effect of aniline content on the dielectric properties of the copolymer, and did not discuss the properties of the copolymer. Anti-corrosion performance
At present, there are few reports on the preparation of anti-corrosion materials by the copolymerization of acrylate and aniline.

Abstract

The invention discloses a dispersed and esterified metal surface treatment agent, the acrylate glue liquor particle surface contains a large number of carboxyl; the preparation method comprises the steps of putting aniline into the acrylate glue liquor, aniline monomer is firstly diffused into the interior of micelle, and dopped with the carboxyl, then aniline occurs polymerization reaction on the emulsion particle surface under the action of an oxidant; a contact angle of the polyaniline coating and water is increased, the adhesive force and waterproof are improved; metal surface is passivated by the coating through electron transfer and oxidation-reduction to create a protective effect; an inorganic component Ti4<+> is introduced to fluotitanic acid modified by silanization and TiO2 particles are formed in a heat curing process, and the TiO2 particles are uniformly filled in the gaps of a silane film, so that the whole silane film is more uniform and dense, the micro electrochemical reaction on the film surface can be effectively inhibited, and the decay resistance is greatly improved.

Description

technical field [0001] The invention relates to a treating agent, in particular to a dispersed esterified metal surface treating 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...
