Abstract

The invention discloses a crystal cluster type inorganic binding agent and a preparation method thereof. The crystal cluster type inorganic binding agent is prepared from the following components in percentage by weight: 20-60wt% of SiO2, 5-23wt% of Al2O3, 5-15wt% of B2O3, 1-5wt% of K2O, 1-8wt% of Li2O, 0-8wt% of Na2O, 1-4wt% of ZnO, 0-5wt% of BaO, 0-5wt% of MgO and 1-7wt% of a crystal cluster nucleating agent. In the smelting process, molten materials are nucleated under the supercooling condition that smelting is conducted at the high temperature, then rapid cooling is conducted to the relatively low temperature, heat preservation is conducted for a period of time, and then water quenching is conducted, a large number of tiny nucleation points are formed, silicate oxyanion groups are deposited and stacked on the nucleation points in combination with the sintering process of stepped heating, and a crystal cluster structure similar to a complexing type is formed, so that the glass ceramics are reinforced and toughened.

Description

technical field

[0001] The invention relates to a superhard material binder, in particular to a crystal cluster type inorganic binder and a preparation method thereof. Background technique

[0002] Superhard material abrasives mainly refer to a grinding tool with a certain shape and strength prepared by using diamond or cubic boron nitride as abrasive grains, with the help of metal, ceramic inorganic matter or resin and other binders. Compared with metal bonds and resin bonds, ceramic inorganic bond products have outstanding advantages such as high processing efficiency, good shape retention, strong self-sharpening, and good high temperature stability, and are widely used in the field of grinding processing.

[0003] In the current vitrified inorganic bond superhard abrasive tools, the main component of the general-purpose vitrified bond is glass. Since glass is a brittle material with poor strength, the overall strength of the superhard grinding block used as a binder is i...
