Embodiment 1

[0022] A polishing disk used for polishing crystal glass. The polishing disk includes a rigid substrate, a bonding layer and a polishing layer, and the rigid substrate and the polishing layer are fixedly connected through the bonding layer. The polishing layer on the polishing disc is made of the following components by mass percentage: 400g of surface-modified diamond abrasives with an average particle diameter of 5 microns; 700g of unsaturated resin with water swelling properties, specifically 191# o-phthalic unsaturated resin Combination of 500g of saturated polyester resin and 200g of polyurethane acrylate; 24g of curing agent, specifically methyl ethyl ketone peroxide; 400g of water-soluble additive, specifically sodium sulfate; 40g of processability adjusting additive, specifically ammonium fluoride. The polishing layer is manufactured by the following method: mix the above components, heat the mold containing the above mixture together with the mixture in an oven to 60°C...

Embodiment 2

[0025] 16 g of a curing accelerator, specifically cobalt octoate, was further added to the polishing layer composition in Example 1. Other components and preparation method are identical with embodiment 1. The curing accelerator can accelerate the decomposition process during the polymerization and curing process, that is, accelerate the progress of the polymerization and curing reaction.

[0026] Using the polishing disc prepared by the above method, polish 14mmX14mm crystal octagonal beads on a full-automatic octagonal bead grinder, the polishing pressure is 125kPa, the polishing disc rotation speed is 630rpm, and the polishing liquid uses tap water. After polishing, the crystal octagonal beads have clear edges and corners, and the surface is bright without scratches. ,, The processing efficiency is twice that of ordinary polishing discs containing cerium oxide, and the polishing disc still has polishing effect after working for 10 working days, and the use time is 2.5 times...

Embodiment 3

[0028] A polishing disk used for polishing crystal glass. The polishing disk includes a rigid substrate, a bonding layer and a polishing layer, and the rigid substrate and the polishing layer are fixedly connected through the bonding layer. The polishing layer on the polishing disc is made of the following components by mass percentage: the average particle diameter is 300g of surface-modified diamond abrasives of 10 microns; the unsaturated resin of water swelling property is 805# unsaturated polyester resin 400g and 350g of polyurethane acrylate; 20g of dibenzoyl peroxide as a curing agent, 20g of cobalt naphthenate as a curing accelerator; 450g of magnesium sulfate as a water-soluble additive, and 40g of ammonium fluoride as an additive for processing performance adjustment.

[0029]The preparation method is the same as in Example 1. The finished polishing disc is polished on a semi-automatic octagonal bead grinding machine with 28mmX28mm crystal square beads. The polishing...

Abstract

The invention relates to a polishing disk for polishing crystal glass. In the polishing disk for polishing crystal glass, a polishing layer comprises the following components in percentage by mass: 5 to 60 percent of grinding material, 10 to 60 percent of unsaturated resin with water swelling property, 0.5 to 5 percent of curing agent, 0.1 to 30 percent of water soluble additive and 0.05 to 8 percent of functional regulating additive, wherein the total mass percentage of the components is 100 percent. The grinding material may be diamond, carborundum and aluminum oxide. The polishing disk solves the problem that the diamond, carborundum, aluminum oxide and the like, which are harder than workpieces, cannot be used as a grinding material on the polishing disk, and has the advantages of high processing efficiency, high wear resistance and long service life.

Description

technical field [0001] The invention relates to a polishing disc for processing crystal glass. Background technique [0002] The processing of crystal glass crafts includes two process steps of grinding (grinding) and polishing, and the workpiece is processed by a grinding disc and a polishing disc respectively. Polishing is different from grinding (grinding). The abrasive discs used for grinding (grinding) usually use particles with a hardness exceeding the workpiece and larger particle sizes as abrasives, such as diamond, corundum, alumina, etc., to remove the workpiece material. China Patent Publication No. is that the patent of CN1490347 adopts carborundum as the grinding disc of abrasive material exactly. The polishing disc for polishing uses soft abrasives with small particle size, and the hardness cannot exceed the workpiece, such as cerium oxide, silica sol, etc., to achieve the removal of workpiece materials. If a high-hardness abrasive is used in the polishing pr...
