Problems solved by technology

[0002] The existing container coating technology generally adopts a three-coat system of epoxy zinc-rich primer, secondary epoxy primer and weather-resistant topcoat, which requires many times of coating, takes a long time, and costs high
These deficiencies arise because the three-coat system requires three applications, each requiring time for the paint to dry

Abstract

The invention discloses a one-component heavy-duty anti-corrosion coating with bottom and surface integrated and a preparation method thereof. The anti-corrosion coating comprises chloroether resin, acrylic resin, epoxy resin, antirust pigment, coloring pigment, filler, auxiliary agent and plasticizer , thinners and solvents. Its preparation method: weigh each component according to the parts by weight; put in a solvent and a diluent in a stirring state, and put in a powdered chloroether resin while stirring; put in bentonite in the dissolved chloroether resin solution while stirring; Put in acrylic resin, wetting and dispersing agent, coloring pigment, anti-rust pigment and filler under stirring state, and carry out sand grinding; put in epoxy resin, plasticizer, polyamide wax paste, defoamer and leveling agent under stirring state , stirring for 0.5~1.5h. The present invention replaces the secondary primer and topcoat system on the outside of the container in the traditional sense, which not only reduces the number of coatings and drying time, but also reduces the time for the workpiece to go offline, greatly shortens the production cycle of the workpiece, and reduces the production cost. cost.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a bottom-surface-integrated single-component heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] The existing container coating technology generally adopts a three-coat system of epoxy zinc-rich primer, secondary epoxy primer and weather-resistant topcoat, which requires many times of painting, takes a long time, and costs high. These deficiencies arise because three-coat systems require three applications, each requiring a certain amount of time for the paint to dry. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a one-component heavy-duty anti-corrosion coating and its preparation method, which replaces the surfacer and top coating system of the traditional container, and not only reduces the number of coating times and drying time , It also reduces the time for the workpiece ...
