Problems solved by technology

[0003] However, the current problem is that the heat resistance of polyurethane is very poor, and its strength will drop sharply with the increase of temperature.
However, there are still some problems that make the cooling effect unsatisfactory: first, when the coolant is cooled, the effect is not ideal for bonded abrasive tools with a temperature resistance lower than 200 degrees; second, for environments with relatively large grinding contact areas ( For example, when the cup-shaped grinding wheel is ground, the contact surface is large) th...

Abstract

The invention provides a grinding tool. The grinding tool comprises the main components of a grinding material, a filler, a binding agent, an antifoaming agent, a curing agent and a stabilizing agent, wherein the filler contains a compound which decomposes and absorbs heat at the temperature of 100 to 800 DEG C. The invention also provides a method for preparing the grinding tool. Compared with the prior art, the self-cooling effect of the grinding tool can be achieved; the work speed and the grinding performance of the grinding tool can be improved; the service life of the grinding tool is prolonged.

Description

Technical field [0001] The invention relates to a grinding tool, specifically a grinding tool used for grinding, grinding and polishing workpieces. Background technique [0002] Organic abrasive tools use organic molecular compounds as binding agents to bond the abrasive grains together to form a grinding tool with a certain rigidity (strength and hardness). Organic abrasives include resin abrasives made of natural and synthetic grease as a binder, and rubber abrasives made of natural or synthetic rubber binders. Organic abrasive tools are generally composed of abrasives, organic binders and pores. Organic binders include resin binders and rubber binders. Among them, polyurethane is a common rubber binder. Polyurethane is a very special performance material with good operating performance. Abrasive tools can be produced through mixing reactions, and the process cost is very low. At the same time, polyurethane is also a soft material with very good elasticity and good bon...
