Problems solved by technology

[0002] Grinding brushes are used to remove excess plug hole resin, copper reduction, and polishing on HDI boards. At present, cylindrical cores are mostly made of cylindrical cores plus a polishing layer covering the surface of cylindrical cores. Cylindrical cores Most of them are inorganic layers such as ceramic tubes, cotton tubes, bakelite tubes, glass fiber tubes, paper tubes or aluminum tubes. When the two layers are bonded to each other, it is easy to form delamination of the inorganic and organic bonding surfaces, making the two layers bonded. Firm and easy to fall off, thus affecting the service life of the brush

Abstract

The invention belongs to the technical field of grinding tools, and particularly relates to a rubber baseorganic ceramic grinding block and a preparation method thereof. The rubber baseorganic ceramicgrinding blockcomprises a ceramic grinding block base body, an adhesive layer bonded to the upper part of the ceramic grinding block base bodyand a rubber layer bonded to the upper part of the adhesive layer. According to the rubber baseorganic ceramic grinding block, the phenomenon of delaminating of an inorganic and organic bonding faceis avoided, the ceramic grinding block basebody and rubberlayer bond firmlyand not prone to being fallen off, and thusthe service life of the grinding block is longer; in addition, by using a PU hot melt adhesive covering film, the grinding block has the advantages of environmental protection and no pollution, long time heating baking and curing are not required, thus energy consumption is low, and rapid production is facilitated; and the preparation method of the rubber baseorganic ceramic grinding block is simple and easy to operate, and is suitable for large-scale production.
