preparation example Construction

[0021] A kind of preparation method of high-precision cutting emery wheel abrasive material, it comprises the following steps:

[0022] (1) Preparation of titanium dioxide sol; when preparing titanium dioxide sol, first dissolve butyl titanate in absolute ethanol under stirring, then add diethanolamine, after the solution is evenly mixed, add ethanol aqueous solution dropwise, continue stirring, and then Aging to obtain titanium dioxide sol; the ratio of butyl titanate, water, diethanolamine and ethanol in the titanium dioxide sol is 1:1:1:(25-28). The invention adopts butyl titanate as an organic precursor, takes ethanol as an organic solvent, and prepares titanium dioxide sol through alcoholysis, hydrolysis and polycondensation reactions.

[0023] (2) Prepare alumina sol; mix aluminum isopropoxide, nitric acid, and deionized water evenly, stir and reflux at 90°C for 10 hours, then let stand for 24 hours, and filter to obtain alumina sol, in which aluminum isopropoxide, nitri...

Abstract

The invention relates to an ultra hard diamond abrasive, and concretely relates to a preparation method of a high-precision cutting abrasion wheel abrasive. The method comprises the following steps: preparing titanium dioxide sol and alumina sol; cleaning diamond particles; immersing the cleaned diamond particles in the titanium dioxide sol, standing the diamond particles, and taking out the diamond particles; heating and drying the diamond particles, and cooling the dried diamond particles; immersing cooled diamond in the alumina sol, and drying and cooling the diamond; and carrying out heat treatment on the cooled diamond in a muffle furnace. The surface of diamond is coated with a titanium dioxide and alumina composite film, so the hydrophilicity of diamond and the wettability of a binder to the diamond in the sintering process are improved, the heat oxidation resistance of the diamond abrasive is effectively enhanced, and the binding force between the sintered binder and the diamond abrasive is improved, thereby the performances of the diamond are greatly improved, the strength of the diamond is increased, and the diamond can be used as an ultra hard diamond abrasion wheel abrasive, and is suitable for grinding ultra hard materials.

Description

technical field [0001] The invention relates to a high-precision cutting grinding wheel, in particular to a preparation method of high-precision cutting grinding wheel abrasives. Background technique [0002] In recent years, with the advancement of science and technology, people's requirements for production tools are developing in the direction of high efficiency, long life and high economy. In many fields, tools of ordinary materials can no longer meet the increasing requirements of laborers. Therefore, diamond The representative diamond grinding tool has developed rapidly, and its application has penetrated into the fields of mechanical processing, automobile manufacturing, aerospace, biology, medical equipment, electronic information, construction, transportation, geological mining and so on. [0003] At present, most of the artificially synthesized diamonds are in the form of powder or fine particles. In order to use diamonds for high-precision and high-efficiency grin...
