Embodiment 1

[0018] 1. Material handling

[0019] The material was polished with 1.0 μm and 0.3 μm alumina powder on a polishing cloth in turn, then placed in 5% hydrochloric acid for 5 min, then placed in deionized water for ultrasonic cleaning for 3 times, each time for 5 min, and finally placed in an Sonicated in water and ethanol for 6 min and then dried for later use.

[0020] 2. Preparation of nickel anti-corrosion enamel with and without rosin acid

[0021] Add 1 mole of abietic acid and 1 mole of nickel acetylacetonate into a round bottom flask, add an appropriate amount of solvent benzyl alcohol, heat and reflux at 200 degrees Celsius for 45 minutes, then transfer it to a pulverizer while it is hot, and pulverize after cooling 2 minutes, then use a volume ratio of 60% ethanol aqueous solution to wash the product, and dry it for 1 hour at a temperature of 80 degrees Celsius to obtain nickel abietate;

[0022] Add 45 parts by weight of dry short oil alkyd resin and 2.0 parts by ...

Abstract

The invention discloses a preparation method of short-oil alkyd resin anticorrosive enamel paint with high corrosion potential, which comprises the steps of taking dry short-oil alkyd resin and prepared nickel abietate as film-forming substances, taking o-xylene as a solvent, then adding activated calcium carbonate, kaolin, carbon black, a leveling agent polyether modified polydimethylsiloxane copolymer and a manganese salt of a drier naphthenic acid, and stirring at a high speed to obtain the short-oil alkyd resin anticorrosive enamel paint with high corrosion potential. The enamel paint hashigh corrosion potential, low corrosion current and high electrochemical impedance, has good local corrosion resistance, and can be applied to heavy anti-corrosion engineering in the fields of house balcony iron-based 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 short oil alkyd resin anticorrosive enamel with high corrosion potential. Background technique [0002] Because petrochemical equipment, pipelines, offshore oil platforms, ships and other equipment are corroded by the atmospheric environment, especially the parts of ship equipment below the waterline are prone to localized corrosion due to long-term immersion in corrosive media such as sodium chloride. The current treatment method is to add a large amount of carcinogenic heavy metal compounds such as trilead tetroxide to the paint formula. However, these carcinogenic heavy metal lead plasmas are continuously precipitated in this type of anti-corrosion coating, which seriously pollutes the ocean, river and soil environment. Serious impact on the ecological environment and human body. However, since there is no suitable alternative technology at present, it is of grea...
