Abstract

The invention provides an asphalt polishing plate. A fluff component is added into the asphalt, so that relative movements of polishing material particles can be driven, movement locus of the polishing material is increased, and polishing rate is improved; and at the same time abrasive dust generated on the surface of an electronic component during a polishing process is brought out, and the component has a dust removing effect. White carbon black is added into the asphalt and plays the effect of nanometer particles, so that the elastic modulus property is effectively improved, and other polishing materials can be held; further, in the synergistic effect of specific component contents of asphalt, wax, fluff and white carbon black, strength and toughness of the moulded asphalt polishing plate are effectively improved, so that the asphalt polishing plate is non-deformable; surface stability of the asphalt polishing plate is high, so that during processing of electronic components, surface flatness and polishing precision of optical elements are effectively improved, and the polishing speed is fast.
