[0024] The preparation technology of high-precision metal bond diamond grinding wheel sheet, it comprises the following steps:

[0025] (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.

[0026] (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...

Embodiment 1

[0034]First dissolve butyl titanate in absolute ethanol under stirring, then add diethanolamine, after the solution is uniformly mixed, then add ethanol aqueous solution dropwise, continue stirring, and then age at room temperature for 1 hour to obtain titanium dioxide sol, in which butyl titanate The ratio of ester, water, diethanolamine, and ethanol is 1:1:1:25; at the same time, mix aluminum isopropoxide, nitric acid, and deionized water evenly, stir and reflux at 90°C for 10h, and then let stand for 24h , and filtered to obtain alumina sol, wherein the ratio of aluminum isopropoxide, nitric acid, and deionized water is: 1:0.2:90. At the same time, the diamond particles are first soaked with hydrochloric acid solution, then rinsed with deionized water until the pH value of the rinse solution is 7, and dried, then ultrasonically cleaned with acetone, then rinsed with deionized water and dried, and then the cleaned diamond Soak the particles in the above titanium dioxide sol,...

Abstract

The invention relates to a diamond grinding disc using a metal adhesive, in particular to a producing technology of a high-precision diamond grinding disc using the metal adhesive. The producing technology comprises the following steps: preparing a titanium dioxide sol and an aluminum oxide sol; washing diamond particles; soaking the washed diamond particles in the titanium dioxide sol and the aluminum oxide sol, fishing out the diamond particles after standing, and after heating and drying, cooling; then, placing the diamond particles in a muffle furnace and carrying heat treatment; mixing and ball-milling a diamond abrasive material, nickel-chromium alloy powder, silicon carbide powder and sodium bicarbonate powder; and then, sieving the materials mixed and ball-milled, re-drying, sintering and unmolding so as to obtain the diamond grinding disc using the metal adhesive. Through soaking the diamond particles in the sols, the surfaces of the diamond particles are coated with a titanium dioxide and aluminum oxide composite film, and the performance of diamond is greatly improved. The producing technology uses the nickel-chromium alloy as the adhesive, the silicon carbide as a filler and the sodium bicarbonate as an auxiliary material, the quality of the produced diamond grinding disc is higher than that of a diamond grinding disc produced by a similar technology, and industrial production is facilitated.

Description

technical field [0001] The invention relates to a metal bonded diamond grinding wheel sheet, in particular to a preparation process for a metal bonded diamond grinding wheel sheet. 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 gr...
