Preferably, the epoxy resin is bisphenol A-type liquid epoxy resin.
Preferably, the percent of pass that the cellulose hydroxypropyl methyl ether crosses 200 mesh screens is not less than 98%, methyl cultivation
For 22-28%, hydroxypropyl base value is 5-10%.
Preferably, it is 1 that the wear resistant filler, which is weight ratio,：The silicon carbide powder of 1.2-2 and the mixture of ceramic.
Preferably, it is 1 that the preservative, which is weight ratio,：The mixture of the aluminium triphosphate and ferrophosphorus powder of 2-5.
Preferably, the curing agent is phenolic aldehyde amine or polyamide；The levelling agent is BYK-354；The dispersion
Agent is one or more in tween, Si Pan, polyvinyl alcohol and polyethylene glycol.
Preferably, it is 1 that the solvent, which is weight ratio,：The dimethylbenzene of 0.5-5 and the mixture of acetone.
The present invention also provides a kind of preparation methods of generator blade corrosion-resistant abrasion coating, include the following steps：
Step (1)：Epoxy resin is first put into stirred tank with solvent first and is mixed, the temperature controlled in stirred tank exists
55-65 DEG C, mixing speed 500-600r/min, mixing time 2-3h are set, organic siliconresin is then placed in and continues to stir, stirred
Time is 50-60min；
Step (2)：Mica powder, nano silicon dioxide, wear resistant filler and cellulose hydroxypropyl methyl ether is added, sets mixing speed
Dispersant is added after stirring to viscous liquid in 540-620r/min, mixing time 1-2h, preservative continues to stir 40-
50min；
Step (3)：Then graphite powder is added in stirred tank and is stirred evenly, mixing speed 700-800r/min, mixing time
