Problems solved by technology

A clear trend of old materials that have exposed many shortcomings and are not suitable for modern production requirements
[0003] At present, metal repair generally adopts methods such as surfacing welding, thermal spraying, electroplating, and electric brush plating. The repair process not only requires expensive equipment, but also consumes a lot of energy, and sometimes the thermal repair process also causes parts deformation, cracks, etc.
[0004] Up to now, some metal repair materials with epoxy resin as the main component have appeared on the market. Most of these repair materials have the following disadvantages: 1. The strength of the cured material is poor, and it is difficult to carry out various mechanical reprocessing; 2. Narrow application range; 3. Poor properties such as wear resistance, aging resistance, high temperature resistance, oil resistance, and weak acid and alkali resistance; 4. Small molecules volatilize during curing, and the curing body shrinks
