Epoxy alloy industry anti-corrosion paint

Abstract

The invention relates to an epoxy alloy industrial anti-corrosive paint, which consists of an ethoxyline resin with high molecular weight, alloy of zinc, magnesium and aluminum, and isophorone diamine. The epoxy alloy industrial anti-corrosive paint is applicable to corrosion prevention of metal in air in coastlands, and is characterized by lower cost than the epoxy zinc-rich paint, long performance life, excellent appearance, and capability of being used as a finish coat alone.

Description

technical field

[0001] The invention relates to an anti-corrosion paint, which is composed of epoxy resin with large molecular weight, aluminum-magnesium-zinc alloy and isophorone diammonia (IPD). It is suitable for atmospheric industrial anticorrosion in coastal areas. Background technique

[0002] In recent years, epoxy zinc-rich paint is the most used industrial anti-corrosion paint to protect metal. Due to the relatively high density of metal zinc powder, in order to prevent the zinc powder from settling or slow down the settling speed of the zinc powder, it is necessary to add a certain amount of anti-settling agent to the paint; the viscosity of the paint will also increase with the addition of the anti-settling agent Therefore, when choosing epoxy resin, it is necessary to choose a resin with a small molecular weight (E44) as much as possible; in order to meet the brushability during construction, a large amount of solvent should be added to the paint, which will ser...
