Problems solved by technology

In order to remove the mineral oil and grinding debris attached to the wafer, a large amount of water and alkaline cleaning agent must be used to achieve the degreasing effect, but the oily wastewater generated will pollute the environment and the subsequent treatment costs are huge

Embodiment 1

[0017] Taking the preparation of 1kg of low-viscosity grinding and cutting fluid as an example, the raw materials and quality ratios used are as follows:

[0018]

[0019] The preparation method of the above-mentioned low-viscosity grinding and cutting fluid is as follows: according to the mass ratio of the above-mentioned raw materials, 343g of deionized water, 285g of glycerin and 350g of 1,2-propanediol are sequentially added to a 2L stirring tank, and the low-speed stirrer is started to heat the material. When the temperature of the material in the mixing tank is 45°C, slowly add 7g of hydroxyethyl cellulose, continue to stir until the cellulose particles are soaked, start the high-speed disperser, stir at 1000 rpm for 60 minutes, add 15g of triethanolamine boron Ester, continue to stir for 120 minutes, and prepare 1 kg of low-viscosity abrasive cutting fluid.

Abstract

The invention provides low-viscosity grinding cutting fluid. The low-viscosity grinding cutting fluid comprises the following components in percentage by mass: 50% to 80% of polyhydric alcohols with 60 to 200 molecules, 18% to 46% of deionized water, 0.5 % to 3% of thickening agent, and 0.3% to 3% of lubricating agent. The low-viscosity grinding cutting fluid can enable the grinding micro powder to be dispersed uniformly, the viscosity of mortar prepared by adopting the low-viscosity grinding cutting fluid is low, and the low-viscosity grinding cutting fluid is used for cutting inorganic nonmetallic materials. The grinding cutting fluid provided by the invention has the characteristics that the cost is low, and the grinding cutting fluid can be cleaned by water easily, meanwhile, the difficulty that abrasive particles subsides fast when the low-viscosity cutting fluid is used by a multi-wire cutting machine is overcome, the suspension stability of abrasive materials in the cutting fluid is achieved effectively, and the cutting fluid is applied to precision cutting to optical substrates, quartz material, ceramic substrates and the like by a small-sized multi-wire cutting machine.

Description

technical field [0001] The invention belongs to the technical field containing abrasives or abrasives, and in particular relates to a low-viscosity grinding and cutting fluid used for multi-wire cutting of inorganic non-metallic materials. Background technique [0002] In recent years, the cutting of inorganic non-metallic materials such as quartz crystals, optical crystals, and ceramics mainly relies on the increasingly perfect multi-wire cutting technology. The friction heat generated, the cutting fluid used earlier at home and abroad mainly uses mineral oil as the main component. This oil-based cutting fluid has good cooling, lubricating, and dispersing properties, but it is flammable and pollutes the environment. There are many problems in oil treatment. With the increasing requirements of environmental protection, the use of cutting oil is less and less. [0003] As a known technology, the polyalkoxy alcohol type grinding and cutting fluid available on the market is us...
