Thermosetting resin wetting agent, and preparation method and application thereof

The invention provides a thermosetting resin wetting agent, and a preparation method and an application thereof. Raw materials of the thermosetting resin wetting agent comprise, by mass, 20-30% of a phenol monomer, 30-45% of an aldehyde monomer, 10-25% of high-boiling point alcohol, 0.1-5% of a catalyst and 15-25% of a viscosity regulator, and the high-boiling point alcohol is alcohol with the boiling point being higher than 150 DEG C. The viscosity of the resin wetting agent is 200-1000 cP/25 DEG C, and the resin wetting agent has certain initial viscosity, low water content, self-curing performance and slow curing speed. Compared with traditional wetting agents, the wetting agent provided by the invention has a wetting performance, also can assist the bonding of resin powder to abrasive and reduce the use amount of the resin powder, avoids the defect of low grinding wheel density caused by fast solidification, and improves the comprehensive performances of grinding wheels. 本发明提供种热固性树脂类润湿剂及其制备方法和应用，所述热固性树脂类润
