Embodiment approach

[0044] As a preferred embodiment, the abrasive sheet includes the following components by weight percentage: 50-60% of bonding agent, 10-15% of diamond abrasive and 20-30% of filler.

[0045] As a preferred embodiment, the filler comprises 10-15% of cerium oxide, 20-30% of cryolite and 10-15% of titanium dioxide by weight percentage. Cerium oxide can significantly improve the smoothness after chamfering; cryolite is conducive to heat dissipation during grinding; titanium dioxide bleaches the color of the product, and avoids staining when the tile is chamfered.

[0046] As a preferred embodiment, the filler also includes one or more components of aluminum oxide, zinc oxide and calcium carbonate in parts by weight, which are mainly to improve life and reduce cost.

[0047] As a preferred embodiment, the filler further comprises 30% to 40% of alumina and 10% to 15% of calcium carbonate by weight.

[0048] As a preferred embodiment, the filler further includes 30% to 40% of zinc ox...

Abstract

The invention discloses a ceramic tile chamfering grinding sheet and a production method thereof, belonging to the field of grinding tools. The binding agent in the grinding sheet at least comprises two components: melamine resin and bismaleimide resin; the grinding sheet It includes the following components by weight percentage: 50-60% of the bonding agent, 10-15% of the diamond abrasive and 20-30% of the filler; the production method includes: step 1, mixing the components uniformly in proportion to obtain Homogeneous mixture; step 2, put the homogeneous mixture into the steel mold and level it, put the nylon hook cloth into the steel mold, and put the indenter; step 3, put the steel mold and the indenter into the hydraulic press for heating and sintering Forming; finally, the tile chamfering polishing sheet is obtained. The beneficial effects of the invention are as follows: the ceramic tile chamfering grinding sheet produced by the formula and production method has the advantages of good wear resistance, good sharpness, good grinding stone effect, convenient replacement and environmental protection of materials.

Description

technical field [0001] The invention relates to the field of abrasive tools, in particular to a ceramic tile chamfering abrasive sheet and a production method thereof. Background technique [0002] At present, the tools used for edging and chamfering ceramic tiles include metal chamfering wheels, resin chamfering wheels and rhombohedral chamfering wheels, and they all have some problems. [0003] (1) Metal chamfering wheel: The wear resistance is the best, but the use effect is the worst. If the grinding amount is slightly larger, the edge will collapse. If the grinding amount is small, some tiles will leak, which is also the proportion of the market. the smallest; [0004] (2) Resin chamfering wheel: expensive, poor sharpness, high hardness of tile glaze or fast walking speed will lead to unsmooth chamfering quality. The market share is also low. [0005] (2) Lattice earth chamfering wheel: The life span is very short, 2 pieces need to be replaced every day, and the enti...
