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 a fully synthetic water-based sapphire cutting fluid and a preparation method thereof. The sapphire cutting fluid comprises the following components in weight percent: 8% to 25% of lubricant; 2% to 10% of antirust agent; extreme pressure 0.25% to 2% of sedimentation agent; 0.5% to 3% of bactericide; 0.2% to 0.8% of wetting agent; 3% to 5% of cosolvent; 4% to 15% of pH value stabilizer; Defoamer 0.2% ~ 0.8%; the balance is water. The fully synthetic water-based sapphire cutting fluid described in the present invention is compounded with reasonable additives, and its lubricating and wetting and penetrating properties are better than those of general water-based sapphire cutting fluids, and can reach the level of oil-based sapphire cutting fluids while avoiding oil-based sapphire cutting fluids. The product has disadvantages such as poor powder settlement, large oil mist, potential safety hazards in case of open fire, and difficult post-processing.

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...
