Abstract

The invention provides a resin binder form diamond abrasive pad. The resin binder form diamond abrasive pad comprises a diamond material layer, a non-woven fabric layer, a binder layer, a polyethylene terephthalate (PET) film layer and a polycarbonate (PC) plate layer with double faces attached with glue in sequence from top to bottom. The abrasive pad is fully filled without holes, the abrasion resistance and cutting efficiency of the abrasive pad are enhanced, an original tiled material layer is replaced with the flexible binder layer containing carbon nanofibers on the back layer of the abrasive pad, and fracture resistance and impact resistance of the abrasive pad are improved.

Description

technical field [0001] The invention relates to the technical field of rough and finish processing of optical lenses, in particular to a resin bond type diamond grinding pad and a preparation method thereof. Background technique [0002] At present, most domestic optical glass processing enterprises are gradually adopting fixed abrasive grinding to replace the traditional free grinding process. The fixed abrasive grinding process has high processing efficiency and product surface quality, and the cutting force of processed products is stable, which can be effectively reduce manufacturing cost. Therefore, the research on consolidated abrasive grinding pads has become a hot spot in the grinding processing industry. Lens Technology Co., Ltd. has applied for an epoxy resin type diamond grinding pad and its preparation method (CN201310403745.8). High efficiency, the prepared grinding pad has a simple structure and high grinding efficiency, but there are problems such as high raw...
