Abstract

The invention relates to a superhard grinding tool ceramic bonding agent, a preparation method of the superhard grinding tool ceramic bonding agent and a superhard grinding tool ceramic bonding agent standard sample, and belongs to the technical field of chemical component detection samples and preparation thereof. The superhard grinding tool ceramic bonding agent is prepared from, by mass percent, 50%-70% of SiO2, 5%-30% of B2O3, 2%-8% of Al2O3, 2%-8% of Li2O, 2%-8% of Na2O, 0.5%-4% of MgO, 0.5%-5% of ZrO2 and 1%-5% of P2O5. The superhard grinding tool ceramic bonding agent can be used for the standard sample of superhard grinding tool ceramic bonding agent detection and analysis. The superhard grinding tool ceramic bonding agent standard sample is reasonable in component design and accurate in definite value; the problem that no superhard grinding tool ceramic bonding agent standard sample exists at present is solved; a qualified standard curve can be drawn on a modern advanced instrument; and efficient and accurate detection on the superhard grinding tool ceramic bonding agent is achieved.

Description

technical field [0001] The invention relates to a vitrified bond for superhard abrasive tools and a preparation method thereof, and a standard sample of vitrified bond for superhard abrasive tools, and belongs to the technical field of samples for chemical composition detection and their preparation. Background technique [0002] As a grinding tool, superhard abrasives are widely used in the fields of high-efficiency precision grinding in aerospace, electronic information, automobile, construction, mining, stone processing and other industries. Superabrasives refer to products made of superabrasives (diamond or cubic boron nitride) as abrasives, ceramics, resins or metals as binders, metals and other materials as substrates, and processed through specific processes. According to different types of binders, superabrasives are divided into three categories: ceramic superabrasives, resin superabrasives, and metal superabrasives. [0003] Vitrified bond for superhard abrasives ...
