Abstract

The invention provides an asphalt polishing disc. By adding fluff components to the asphalt, it can not only drive the relative movement of the polishing material particles, increase the movement trajectory of the polishing material, thereby increasing the polishing rate, but also reduce the surface of the electronic components during the polishing process. It has the function of chip removal; by adding white carbon black to the asphalt, it can play the role of nanoparticles, effectively improve the elastic modulus performance, and can hold other polishing materials. Further, in asphalt, wax Under the synergistic effect of the specific component content of , fluff and white carbon black, the strength and toughness of the asphalt polishing disc after molding are effectively improved, making it difficult to deform, so that the asphalt polishing disc of the present invention has high surface stability and is used for processing electronic components When , it can effectively improve the surface flatness and polishing precision of the optical element, and the polishing speed is fast.
