A kind of anti-corrosion wear-resisting repairing material

Abstract

The invention discloses an anti-corrosive wear-resisting patching material which comprises the three components A, B and C, wherein the component A comprises vinyl ester resin and a coupling agent, the component B comprises ceramic packing, nitrile rubber and a curing agent, and the component C is a SBS (Styrene Butadiene Styrene) tackifier. Compared with existing patching materials, the anti-corrosive wear-resisting patching material disclosed by the invention can be cured at normal temperature without special curing heating equipment and plants, is good in temperature resistance, and can be used in a range from minus 60 DEG C to 232 DEG C.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an anti-corrosion and wear-resistant repair material for equipment or pipelines. Background technique [0002] CN102504204A discloses a wear-resistant material composited with organic polymers and silicon carbide that can be used to repair equipment and pipelines. However, the wear-resistant material needs to be cured at high temperature (80-100°C) when repairing equipment and pipelines, which is difficult for large-scale equipment or Long pipes increase the difficulty of curing, and the repair layer can only be used at a temperature of -40 ~ 150 ° C, especially in energy, chemical, electric power and other industries, its corrosion resistance under high temperature conditions is very poor, resulting in the application of During the process, the following situations often occur: (1) Adhesion decreases and flakes fall off; (2) Mechanical strength decreases; (3) The coating’s r...
