Technical Field

The invention belongs to the technical field of dies, and particularly relates to a formula and a preparation method of a metal bond elastic grinding block.

Background

At present, in some ceramic glazed tiles on the market, the surface enamel of the ceramic glazed tile is raised into points or patterns, the points of the enamel are required to be roughly ground and polished, and a full-resin-diamond segment elastic grinding tool is generally adopted for grinding under the condition, but the grinding tool is high in consumption speed, poor in wear resistance, small in grinding amount and low in grinding efficiency, and cannot achieve a full polishing effect. Therefore, further improvements are necessary.

Disclosure of Invention

The invention aims to provide a formula of a metal bond elastic grinding block and a preparation method thereof.

In order to achieve the purpose, the invention adopts the following technical scheme:

the formula of the metal bond elastic grinding block comprises the following raw materials in parts by weight:

2-4 parts of diamond, 50-60 parts of electrolytic copper powder, 4-7 parts of cobalt powder, 4-6 parts of electrolytic nickel powder, 10-17 parts of tin powder and 20-30 parts of carbonyl iron powder.

The fineness of the diamond is 200-230 meshes, the fineness of the electrolytic copper powder is 480-500 meshes, the fineness of the cobalt powder is 190-200 meshes, the fineness of the electrolytic nickel powder is 780-800 meshes, the fineness of the tin powder is 290-300 meshes, and the fineness of the carbonyl iron powder is 1100-1200 meshes.

A preparation method of a metal bond elastic grinding block comprises the following steps:
