Abstract

The invention discloses a polishing abrasive disc for polished crystal tiles and a preparation method thereof. The polishing abrasive disc comprises the following materials in percentages by weight: 5-10% of main abrasive material diamond particles, 20-30% of phenolic resin, 10-15% of melamine resin, 25-35% of an auxiliary abrasive material and 25-40% of an auxiliary polishing material. The preparation method comprises the following steps: proportioning the materials to prepare a mixed powdery material; and then putting the material in a mould to be heated and sintered and moulded. According to the polishing abrasive disc for polished crystal tiles provided by the invention, two resins: phenolic resin and melamine resin which are mixed in a specific proportion are creatively adopted, so that an important breakthrough is obtained in the polishing aspect of the polished crystal tiles. The phenolic resin accounts for 20-30% and the polishing property of the phenolic resin is fully utilized; the melamine resin accounts for 10-15% and solves the problem that the sharpness of the phenolic resin is short. The two are reasonably matched in use according to the proportion, so that the polishing effect is extremely excellent. The brightness of the product in the market only reaches 15-30 degrees, but the brightness of the product disclosed by the invention can reach 30-50 degrees, and the polishing abrasive disc for polished crystal tiles is quite obvious in advantage.

Description

technical field [0001] The invention relates to the field of diamond grinding tools, in particular to a polishing grinding plate for polished crystal bricks and a preparation method thereof. Background technique [0002] Polished crystal tiles have high hardness, and the surface layer has 3mm thick glass-ceramics. During the wet grinding process of polished crystal tiles, the sharpness of grinding and polishing products is high, and products with low sharpness cannot be quickly polished and smoothed to smooth the glass-ceramic surface. In addition, the photometric characteristics of polished crystal bricks are also very important, which directly affects the product quality of polished crystal bricks. At present, the commonly used grinding and polishing products for polishing crystal tiles are diamond grinding discs used for assembly line processing. The sharpness and glazing performance are not good, especially the glazing performance. The luminosity of products currently on...
