Problems solved by technology

[0002] Polishing of glass jewelry requires a polishing disc. In the traditional sense, the polishing efficiency of the polishing disc is determined by the composition ratio of the polishing powder (cerium oxide and alumina composite powder) and the formula ratio of the polishing disc. Currently, the polishing disc formula produced on the market uses polishing The powder composition is more than 55%; however, cerium oxide is a metal oxide, which has a great impact on the environment, and cerium oxide is toxic to the human body: the salt of cerium oxide rare earth elements can reduce the content of prothrombin and make it inactive; and Inhibit the formation of thromboplastin, inhalation of cerium-containing dust will cause occupational pneumoconiosis, and the cost of rare earth itself is high. The current consumption of rare earth in Pujiang County is 1000-1500 tons per year; in summary, it is necessary to develop a polishing powder that can reduce polishing powder A high-quality, durable polishing disc with high content and polishing efficiency will be the top priority

Abstract

The invention discloses an optical glass polishing disk and a manufacturing method thereof. A polishing disc raw material comprises the following components in percentage by weight: 30-45% of polishing powder, 6-18% of resin, 10-22% a pore forming substance, 0.2-20% of aminolipin, 8-18% of a curing agent and 8-18% of a catalyst. By improving the formula of the polishing disc, the dosage of the polishing powder is reduced directly, the manufacturing cost is lowered, the environmental pollution is reduced, and damage on human body can be also reduced. The added aminolipin organic high-molecularpolymer in cross-linking reaction with resin is high in adhesive force and good in toughness. The polishing powder after coordinated bonding is high in Moh's hardness, and the grinding force of the optical glass polishing disk is enhanced; finally, the polishing disc is high in light out-coupling efficiency, good in polishing effect and durable. 300-400 tons of rare earth polishing powder can be saved by only one county of Pujiang every year.
