Problems solved by technology

However, oil-based products have some defects as cutting fluids: first, there is a large oil mist on site, with a certain pungent smell, and long-term exposure is harmful to the health of workers; second, there are certain safety hazards when oil products encounter open flames; Discharge treatment is difficult, and there are many sulfides in the oil sludge, which affects the environment
Contains no wetting agent, which may cause dry cutting wear due to insufficient wetting and penetration when cutting at high depths of cut

Abstract

The invention provides total-synthesis water-based cutting fluid for sapphire and a preparation method of the cutting fluid. The cutting fluid for the sapphire comprises the following components of: in percent by weight, 8-25% of lubricant, 2-10% of rust inhibitor, 2-7% of an extreme-pressure additive, 0.25-2% of a settling agent, 0.5-3% of fungicide, 0.2-0.8% of a wetting agent, 3-5% of a cosolvent, 4-15% of pH stabilizer, 0.2-0.8% of defoamer and the balance water. According to the total-synthesis water-based cutting fluid for the sapphire, the reasonable additives are adopted for compounding, lubricating and wetting permeation performance of the cutting fluid are better than common water-based cutting fluid for sapphire, the total-synthesis water-based cutting fluid for the sapphire canreach the level of oil-based cutting fluid for the sapphire, and meanwhile the defects of poor powder sedimentation, large oil mist, potential risks for open flames, difficult post-processing and thelike of the oil-based product are avoided.

Description

technical field [0001] The invention belongs to the technical field of sapphire crystal cutting and cutting fluid, and in particular relates to a fully synthetic water-based sapphire cutting fluid and a preparation method thereof. Background technique [0002] As an important technical crystal, sapphire crystal is widely used in high-tech fields such as laser, integrated circuit, precision instrument, mechanical automation, military industry and aerospace. To meet these high-precision industry demands, it is becoming more and more important to process high-quality sapphire devices quickly and efficiently. However, due to the high hardness and high strength of sapphire itself, the tool is easy to wear during processing, resulting in reduced processing efficiency and even product chipping. Therefore, sapphire processing has higher requirements for processing fluid than ordinary glass cutting fluid. [0003] Traditional sapphire cutting, especially the cutting of sapphire crys...
