Abstract

The invention relates to a coating, in particular to a modified epoxy phenolic resin coating and a preparation method thereof. The coating is prepared by mixing, grinding and filtering epoxy resin, phenolic resin, zirconium oxide powder and an adhesion enhancer. Epoxy resin and phenolic resin are used as base materials, so that the coating is high in strength, not prone to abrasion and high in corrosion resistance. The modified material zirconium oxide powder and the adhesive force enhancer are added into the base material, so that the adhesive force and mechanical properties of the coating can be improved, the binding force between the coating and metal is increased, and the coating is not liable to strip off.

Description

technical field [0001] The invention relates to a coating, in particular to a modified epoxy phenolic resin coating for anti-corrosion coating on metal materials and a preparation method thereof, and is especially suitable for offshore oil and gas gathering and transportation pipes. Background technique [0002] Metal materials are damaged by the action of the surrounding medium, which is called metal corrosion. During corrosion, a chemical or electrochemical heterogeneous reaction occurs on the surface of the metal, which converts the metal into an oxidized (ionic) state. This will significantly reduce the mechanical properties of metal materials such as strength, plasticity, and toughness, destroy the geometry of metal components, increase wear between parts, deteriorate electrical and optical physical properties, shorten the service life of equipment, and even cause disasters such as fire and explosion. sex accident. Therefore, when metal materials are used, their surfa...
