Method for preparing anti-wear, anti-corrosion nano composite epoxy asphalt repair paint

Abstract

The present invention discloses the preparation process of antiwear, anticorrosive nanometer composite epoxy asphalt repair paint. The repair paint has organic surfactant coated nanometer level functional powder in 2-15 wt% added, and the nanometer level functional powder is one or two selected from titania, silica, zinc oxide, nickel oxide, alumina, chromium oxide, manganese oxide and barium sulfate. The nanometer level powder is first dispersed in small amount of epoxy resin through ball milling, sand grinding or high speed emulsification to form slurry, and the slurry is then mixed with the main epoxy asphalt repair paint component to obtain the antiwear, anticorrosive nanometer composite epoxy asphalt repair paint. The composite epoxy asphalt repair paint is used in repairing coated film and has high anticorrosive performance and high scratch resistance.

Description

technical field

[0001] The invention relates to a preparation method of an epoxy resin-based coating composition, and more specifically relates to a preparation method of an epoxy asphalt repair coating added with nano functional powder. Background technique

[0002] The ocean is a very corrosive environment. Almost all parts of marine engineering facilities and marine ships need anti-corrosion protection. Therefore, the scope of marine anti-corrosion coatings is very wide, and they all belong to the category of heavy-duty anti-corrosion coatings, such as anti-rust Primer, hull paint, deck paint, interior cabin paint, container paint, seaport facilities and platform paint, oil tank paint, seawater cooling pipeline and offshore oil pipeline paint, etc. Zinc-rich coatings are currently one of the hot spots in marine engineering protective coatings. The earliest zinc-rich paint was invented by Australian Victov Nightingale in the 1930s, an inorganic zinc-rich paint prepared by...
