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, and then placed in deionized water for ultrasonic cleaning for 3 times, each time for 5 min, and finally placed in Sonicated in absolute ethanol for 6 min and 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 0.8 mole of nickel chloride into the pulverizer, grind and disperse at 3000 rpm for 3 minutes, then transfer to a crucible, and react in a reaction box at 180 degrees Celsius for 40 minutes. minute, then proceed to pulverizer while hot, pulverize after cooling for 3 minutes, then adopt volume ratio to be 40% ethanol aqueous solution washing product 3 times, dry 1 hour under 80 degree of temperature to obtain nickel abietate;

[0022] Add 50 parts by weight of dry short oil alkyd resin and 2 parts by ...

Abstract

The invention discloses a simple preparation method of rosin-based short-oil alkyd resin anticorrosive enamel paint, which comprises the following steps: by using dry short-oil alkyd resin and nickelabietate prepared by hot melting reaction as film-forming substances and o-xylene as a solvent, then adding activated calcium carbonate, kaolin, carbon black, leveling agent polyether modified polydimethylsiloxane copolymer and a manganese salt of a drier naphthenic acid, and stirring at a high speed to obtain the rosin-based short-oil alkyd resin anticorrosive enamel paint. The enamel paint has high 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 simple preparation method of rosin-based short-oil alkyd resin anticorrosion enamel. 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 great significa...
