The invention relates to an
adhesive for
grinding wheel meshes and a preparation method of the
adhesive. The
adhesive comprises 80-110 parts of
thermoplastic phenolic resin, 1-6 parts of curing agent, 20-40 parts of thermosetting
phenol resin liquid, 60-140 parts of
alcohol, 0.5-2 parts of flexibilizer, 0.5-2 parts of
coupling agent and 0.5-2 parts of
plasticizer. The preparation method includes adding the
alcohol into a stirrer, adding the
thermoplastic phenolic resin whiling stirring, stirring for 3-4 hours, adding the thermosetting
phenol resin liquid containing the
coupling agent, the
plasticizer and the flexibilizer containing the
alcohol after phenolic resin blocks are totally dissolved, stirring for 3-4 hours prior to adding the curing agent, and continue stirring for 4-6 hours to obtain the adhesive. The adhesive prepared by the method can be ready-to-use and ready-to-prepare and is good in stability
pollution and mainly used for impregnation of the
grinding wheel meshes,
pollution and waste are reduced,
brittleness of the
grinding wheel mashes, strength and adhesive performance are improved, and accordingly
wear resistance of grinding wheels is improved, highest rotation speed of the
grinding wheel is increased, and service life of the
grinding wheel is improved.
