a) Adding 3g of initiator TPO into pentaerythritol triacrylate to be fully dissolved, and adding 15-S-15 surfactant into the initiator TPO to obtain uniform resin liquid;
b) Then, 650g of 2500# ceramic alumina abrasive, 300g of tetrahydrofuran acrylate and 100g of epoxy resin powder coating are uniformly mixed;
c) Spraying the mixed resin liquid obtained in the step a) on the mixed resin liquid obtained in the step b), stirring while fully wetting and uniformly mixing to obtain high-viscosity slurry, wherein the temperature of the slurry is controlled to be 30-40 ℃ again, and the viscosity is controlled to be 25000-35000Pc.s;
d) And then transferring the slurry onto a polyester film substrate through a slit, extruding the polyester film substrate through a prismoid roller, and carrying out setting curing and thermocuring by using a UV light source to obtain the 2500# grinding consumable.
5. The method for preparing a grinding consumable material suitable for high-rotation-speed and low-pressure grinding according to claim 3, wherein the 600# grinding consumable material is matched with a mechanical grinding device under the conditions of pressure F =10N, r =5500r/min and time t =60s.
6. The method for preparing a grinding consumable suitable for high-speed and low-pressure grinding according to claim 4, wherein the 2500# grinding consumable is matched with a mechanical grinding device under the conditions of pressure F =10N, r =5500r/min and time t =60s.
