Abstract

The invention discloses a preparation method of long-oil alkyd resin anticorrosive enamel paint with high corrosion potential, which comprises the steps of by taking dry long-oil alkyd resin and zincabietate synthesized by the method as film-forming substances and isobutanol as a solvent, adding organic kaolin, organic bentonite, carbon black, simethicone and aluminum naphthenate serving as a drier, and stirring at a high speed to obtain the simple rosin-based long-oil alkyd resin anticorrosive enamel paint. The enamel paint has low corrosion current, high corrosion potential and large electrochemical impedance, that is, the enamel paint has good local corrosion resistance, and can be applied to anti-corrosion engineering in the fields of house balcony metal base railings, petrochemical equipment, pipelines, offshore oil platforms, wharf facilities, ships and the like.

Description

technical field

[0001] The invention relates to the field of enamel, in particular to a preparation method of high corrosion potential long-oil alkyd resin anticorrosion enamel. Background technique

[0002] Due to the low potential of petrochemical equipment, pipelines, offshore oil platforms, ships and other metal material equipment, they are extremely vulnerable to corrosion by the atmospheric environment, especially the parts of ship equipment below the waterline are extremely vulnerable to corrosion due to long-term immersion in corrosive media such as sodium chloride. It is easy to cause severe localized corrosion. The current treatment method is to add a large amount of heavy metal compounds such as lead tetraoxide to the paint formula. However, these highly toxic heavy metal lead plasmas are continuously precipitated in this type of anti-corrosion coating, which seriously pollutes the ocean, river and soil environment, and affects the global ecological environment. ...
