Double-component aluminum metal anti-corrosion repairing agent and preparation method thereof

Abstract

The invention discloses a double-component aluminum metal anti-corrosion repairing agent and a preparation method thereof. The repairing agent comprises the following components in parts by weight: 20 to 25 parts of epoxy resin, 10 to 15 parts of curing agent, 18 to 23 parts of reinforced stuffing, 10 to 15 parts of coupling agent, 5 to 8 parts of micro powder, 3 to 6 parts of active agent, 1 to 3 parts of tackifier, 0.1 to 0.5 part of defoaming agent and 30 to 35 parts of thinning agent. A membrane layer formed by the repairing agent on the surface of an aluminum base material can resist the high temperature of 700 DEG C and has no phenomenon of obvious stripping, burring and the like. The double-component aluminum metal anti-corrosion repairing agent is excellent in water resistance, alkali and acid resistance and weather resistance.

Description

technical field

[0001] The invention relates to an aluminum metal repairing agent. Background technique

[0002] Some aluminum alloy equipment that needs to work under high temperature conditions, such as aluminum alloy fan blades, aluminum alloy quenching furnaces, etc., generally need a repair agent to repair when they are damaged or broken. The key technology of bonding is a two-component (or multi-component) cement-like composite material composed of high molecular polymer, metal powder, ceramic powder and fiber, which is widely used in wear-resistant, corrosion-resistant repair and pre-treatment of parts. Protective coating and used to repair various defects of parts (such as cracks, scratches, dimensional tolerances, casting pores, sand holes) and sealing plugging, etc. The process is simple and easy, just mix the two components in proportion, It is applied on the surface that has been derusted and degreased, and can be repaired after curing. It is a labor-saving,...
