Embodiment 1

[0038] First, weigh the material with the following weight percentage distribution: 24 # Brown corundum 60 parts, 24 # 20 parts of white corundum, 20 parts of silicon carbide; 5 parts of resin solution, 10 parts of phenolic resin powder, and 3 parts of calcium sulfate whisker; the resin solution is prepared by phenolic resin solution and epoxy resin at a mass ratio of 8:2.

[0039] Its ingredients are:

[0040] Step 1 Mixing: Use a double-pot countercurrent mixer, pour the abrasive into the upper pot, add the resin solution and stir for 2 minutes, then add calcium sulfate whiskers and stir for 3 minutes, add phenolic resin powder to the lower pot, and stir for 5 minutes Then mix the ingredients in the upper and lower pots and stir evenly; put them into the vibrating sieve again to sieve out the hard lumps of the dough to obtain the spare molding material.

[0041] Step 2 Forming: Weigh the spare molding material, first pour the spare molding material required for half a grin...

Abstract

The invention discloses a calcium sulfate whisker reinforced resin grinding wheel, which comprises a grinding wheel body, wherein the grinding wheel body is formed by adhering and curing a grinding material, a reinforced mesh, a binding agent and a filling agent according to the following weight proportions; the grinding material comprises 50-60 parts of 20# brown corundum, 20-30 parts of 24# white corundum and 10-20 parts of silicon carbide; the reinforced mesh is a glass fiber and/or carbon fiber reinforced grinding wheel mesh; the binding agent comprises 5-7 parts of resin liquid and/or 10-12 parts of phenolic resin powder; the filling agent comprises 3-5 pars of calcium sulfate whisker; the resin liquid is prepared by phenolic resin liquid and epoxy resin according to the mass proportion of 8:(2-3); the calcium sulfate whisker is fiber-shaped single crystal, the diameter is 1-4mum, and the length is 20-80mum. The calcium sulfate whisker reinforced resin grinding wheel has the advantages that the grinding ratio is good, the safety speed is high, the impact-resistant property is strong, and the pollution to the working environment is little.

Description

technical field [0001] The invention belongs to the technical field of cutting grinding wheels, and in particular relates to a calcium sulfate whisker-reinforced resin grinding wheel and a manufacturing method thereof. Background technique [0002] Resin grinding wheel uses resin as an adhesive to bond loose abrasives and consolidate them into a thin slice grinding wheel of a certain shape. It is mainly used in the cutting of metal profiles. During the preparation of a general grinding wheel, the grinding wheel body is composed of abrasives and a mesh, and the abrasives are embedded in the mesh. Among them, abrasive, bond and porosity are the three basic elements of grinding wheel. Due to different abrasives, bonding agents and grinding wheel manufacturing processes, the performance of grinding wheels varies greatly. Therefore, suitable grinding wheels must be prepared according to specific conditions. [0003] The resin grinding wheel after adding the bond has the advant...
