| titleOfInvention | Sponge sand for grinding electronic parts and production method thereof |
| abstract | The invention discloses sponge sand for grinding electronic parts and a production method thereof, and the technical scheme is that the sponge sand comprises a sponge base layer, a primer layer adhered to the surface of the sponge base layer, an adhesive layer adhered to one side of the primer layer, which is far away from the sponge base layer, and an abrasive layer adhered to one side of the adhesive layer, which is far away from the primer layer; the production method comprises the following steps: a. cutting the anti-sticking adhesive tape; b. laying an anti-sticking adhesive tape; c. coating an adhesive layer; d. planting sand; e. drying the adhesive layer; f. uncovering the anti-sticking adhesive tape; g. laying an elastic layer; h. pressing the adhesive layer; i. drying the bottom glue layer; j. drying; k. cutting; offer the chip groove of a plurality of crisscross distributions on the layer of polishing, the piece that produces in the middle of the process of polishing can enter into in the middle of the chip groove to spill in the middle of the chip groove, make sponge sand piece in the middle of the process of using, be difficult to reduce the effect of polishing. |
