Abstract

The invention discloses an antirust coating for a metal pipeline. The antirust coating comprises the following ingredients in parts by weight: 30-50 parts of dicyanodiamide modified phenol-formaldehyde resin, 20-25 parts of epoxy acrylate, 5-12 parts of talcum powder, 10-20 parts of stearic acid, 6-8 parts of butanediol, 5-9 parts of glass powder, 3-6 parts of zinc chromate, 10-15 parts of macromolecular polymer. Through mixing and curing of the antirust coating and epoxy acrylate, the product has better adhesive power and antirust property, and is faster in curing speed, and the production efficiency can be effectively improved; the product does not contain any organic solvent, has no emission of volatile organic compounds (VOC), does not contain elements of Pb, Cr, Zn and the like, and has no environmental pollution in the production and use process, thus being a high-efficiency and green and environment-friendly coating.

Description

technical field [0001] The invention belongs to an antirust coating for pipelines, in particular to an antirust coating for oil pipelines. Background technique [0002] Among various anti-corrosion measures, the use of epoxy powder coatings as pipeline anti-corrosion coatings is currently considered to be an effective method. However, the production and coating process of powder coatings require special equipment, and the floor area is relatively large. At the same time, powder coatings are not suitable for thin coatings, only for thick coatings, and the shortcomings of powder coatings such as long curing time and high energy consumption are not suitable. The development trend of modern high-speed production lines. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a pollution-free and [0004] Rust preventive coating for metal piping with good water, chemical, abra...
