AI Technical Summary

Technical Problem

Graphene tends to agglomerate in metal binders, resulting in uneven dispersion and weak interfacial bonding in diamond abrasives, which affects the stability of abrasive performance. Furthermore, metal binders have insufficient heat dissipation performance without coolant, leading to low abrasive utilization efficiency.

Method used

Graphene modified with hydroxylated boron nitride and iron-based metal binders were used, and the dispersibility and interfacial compatibility of graphene in the metal binder were improved by modification with silane coupling agents. The thermal conductivity of hexagonal boron nitride was also used to optimize the binder performance.

Benefits of technology

It improves the mechanical strength and thermal conductivity of diamond grinding wheels, reduces the coefficient of thermal expansion, and increases the service life and performance stability of grinding tools.

Abstract

This application discloses a graphene-modified iron-based metal binder, its preparation method, and its application, relating to the field of diamond grinding wheel technology. The graphene-modified iron-based metal binder comprises, by weight percentage: Fe 40-60%, Co 15-30%, Cu 15-30%, Sn 4-15%, and 0.1-1% hydroxylated boron nitride-modified graphene. The hydroxylated boron nitride-modified graphene is composed of the following raw materials in parts by weight: 1-2 parts silane-modified graphene oxide, 80-150 parts ethanol, 40-80 parts deionized water, 8.5-12.5 parts acetic acid, and 0.5-1 parts hydroxylated boron nitride. Using hydroxylated boron nitride-modified graphene in an iron-based metal binder, and then applying it to the preparation of diamond grinding wheels, can further improve the bending strength of diamond grinding wheels, reduce the coefficient of thermal expansion, and improve the thermal conductivity.
