Abstract
The invention discloses a diamond grinding wheel with high oxidation resistance, and belongs to the technical field of grinding wheel manufacturing. The invention is prepared from the following raw materials in parts by weight: 40-45 parts of diamond abrasive, 20-23 parts of green silicon carbide, 3-4 parts of aluminum oxide, 1-2 parts of copper powder, 1-2 parts of cobalt powder, 2-3 parts of chromium oxide, 1-2 parts of carbon black, 7-9 parts of bismaleimide and 7-9 parts of melamine resin. The oxidation resistance of the diamond grinding wheel is improved by adding resins with different heat resistance and hardness, and the grinding performance is improved by blending modification of bismaleimide and melamine resin respectively.
Description
Technical Field
The invention relates to the technical field of grinding wheel manufacturing, in particular to a diamond grinding wheel with strong oxidation resistance.
Background
The grinding tool of the abrasive grinding tool is a general name of the product of the abrasive grinding tool, is a name of industrial teeth and a name of a product of a dissolving agent, and during grinding, a grinding tool of the common abrasive grinding tool is used for machining parts to be machined so as to meet certain technical requirements. Thus, the abrasive tool product can directly affect the surface quality of the product.
Disclosure of Invention
The invention aims to provide a diamond grinding wheel with strong oxidation resistance.
The technical scheme of the invention is as follows: a diamond grinding wheel with strong oxidation resistance is prepared from the following raw materials in parts by weight: 40-45 parts of diamond abrasive, 20-23 parts of green silicon carbide, 3-4 parts of aluminum oxide, 1-2 parts of copper powder, 1-2 parts of cobalt powder, 2-3 parts of chromium oxide, 1-2 parts of carbon black, 7-9 parts of bismaleimide and 7-9 parts of melamine resin.
According to a further technical scheme, the ratio of the bismaleimide to the melamine resin is 1: 1.
The invention has the beneficial effects that:
aiming at the defect that phenolic resin in a diamond grinding tool is easy to oxidize in the prior art, the oxidation resistance of the diamond grinding wheel is improved by adding resins with different heat resistance and hardness, and the grinding performance is improved by blending modification of bismaleimide and melamine resin respectively.
Detailed Description
The invention will be further illustrated and understood by the following non-limiting examples.
The invention relates to a diamond grinding wheel with strong oxidation resistance, which is prepared from the following raw materials in parts by weight: 40-45 parts of diamond abrasive, 20-23 parts of green silicon carbide, 3-4 parts of aluminum oxide, 1-2 parts of copper powder, 1-2 parts of cobalt powder, 2-3 parts of chromium oxide, 1-2 parts of carbon black, 7-9 parts of bismaleimide and 7-9 parts of melamine resin.
During preparation, the ratio of the bismaleimide to the melamine resin is controlled to be 1: 1.
The bismaleimide has the characteristics of good heat resistance, high hardness and high impact strength, but has higher curing temperature and poorer technological property, and is not suitable for directly using pure grease as a module;
the melamine resin has good heat resistance, high hardness and low impact strength, but experiments show that when bismaleimide: when the ratio of the melamine resin to the melamine resin is 1:1, the product has better wear resistance.
Therefore, the invention realizes the oxidation resistance of the diamond grinding wheel by adding the bismaleimide and the melamine resin into the original raw material components.
Claims (2)
