Abstract

The invention provides an anticorrosive paint for copper alloy and a manufacturing method thereof, which can solve the problems of the prior art that the binding force of the coating layer is inferior, the service life of the coating layer is influenced, and the like. The invention relates to an anticorrosive paint with excellent anticorrosive property and strong adhesive force with copper alloy, which is manufactured by using epoxy resin enhanced with polyurethane as a base resin, improved aromatic amine curing agent as a curing agent and adding an accelerating agent with a certain amount of adhesive force.

Description

technical field [0001] The invention relates to an anti-corrosion coating, in particular to an anti-corrosion coating for copper alloy and a manufacturing method thereof. Background technique [0002] Copper alloy (copper alloy) is an alloy composed of pure copper as the base and adding one or several other elements. It has excellent electrical conductivity, thermal conductivity, ductility and other physical and mechanical properties, and its corrosion resistance is also relatively prominent. It is widely used in fields such as ships and ships, and is mainly used to make electrical equipment such as generators, busbars, cables, switchgear, transformers, heat exchangers, pipes, flat collectors for solar heating devices, and other heat-conducting equipment, and pipes for shipbuilding industry equipment. , propeller, etc. However, copper alloys are unstable in the atmosphere and are easily oxidized and discolored, especially in high temperature, high humidity, high salt, conta...
