Embodiment

[0012] The casting method of a kind of resin grinding wheel of the present embodiment, comprises abrasive material, phenolic resin, coagent and wetting agent; Coagent is hydroxymethylated lignin, and lignin is alkali lignin, calcium lignosulfonate or sodium lignosulfonate. The mass ratio of abrasive, coagent, wetting agent and phenolic resin is 5:0.25:0.7:1. Preferably, inorganic fillers are also included; the inorganic fillers are iron sulfide and cryolite. Preferably, the mass ratio of iron sulfide, cryolite and phenolic resin is 1.1:0.25:1;

[0013] Hydroxymethylated lignin was prepared as follows:

[0014] A) Lignin solution is obtained after mixing lignin with lye;

[0015] B) Add aldehyde compounds to the above lignin solution, heat up the reaction, and precipitate hydroxymethylated lignin. The lye is sodium hydroxide solution, potassium hydroxide solution, rubidium hydroxide solution or cesium hydroxide solution, lignin The mass ratio of lye to lye is 0.3:1, aldehyd...

Abstract

The invention discloses a casting method of a resin grinding wheel. According to the casting method of the resin grinding wheel, abrasive materials, phenolic resin, an active auxiliary and a wetting agent are adopted. The active auxiliary is hydroxylated lignin. According to the casting method of the resin grinding wheel, the hydroxylated lignin is used as the active auxiliary, participates in resin solidification in the manufacturing process of the resin grinding wheel and enables a solidified substance to form a micropore structure when the resin is solidified, and therefore the pore ratio of the resin grinding wheel is increased; and in this way, the resin grinding wheel has higher cut resistance degree and cutting efficiency.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a casting method of a resin grinding wheel. Background technique [0002] In the prior art, the method of increasing the pores of the resin grinding wheel is mainly to select different types of abrasives or add inorganic fillers when pressing the grinding wheel blank. By adding inorganic fillers to increase the proportion of pores in the resin grinding wheel, if the proportion of inorganic fillers is too small, the proportion of pores will be small, and if the proportion of inorganic fillers is too large, the strength of the grinding wheel will be reduced and the grinding ability will be reduced. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art field, the object of the present invention is to provide a casting method of resin grinding wheel, the cast resin grinding wheel has a higher air hol...
