Problems solved by technology

Because the cutting fluid contains chlorine, it cannot meet the RoHS standard
[0007] The cutting fluid provided in another patent application is not completely soluble in water, which makes it difficult to rinse the workpiece; or contains heavy metal elements (such as molybdenum)
[0008] Therefore, the above-mentioned cutting fluid or cutting fluid has more or less defects in terms of lubricity, permeability, cooling, cleaning, rust prevention and environmental protection.

Embodiment 1

[0025] An environment-friendly water-based sapphire cutting fluid is made from the following raw materials in parts by weight:

[0026]

[0027]

[0028] Preparation method: first prepare the extreme pressure agent according to the ratio of the three components in the extreme pressure agent, and then mix the above ten components to obtain the cutting fluid of the present invention.

[0029] In the present invention, the dispersant polyethylene glycol has good water solubility, and can also be used as a solvent, auxiliary agent, and suspending agent in the cutting fluid system; Flow away quickly. Moreover, the molecular weight of polyethylene glycol-400 is small, and it has good wetting ability to the processed cut surface during high-speed frictional movement, and its thermal stability is excellent. In the present invention, the used triethanolamine borate has good extreme pressure anti-wear properties, wettability, and good reactivity, and the extreme pressure agent co...

Embodiment 2

[0031] An environment-friendly water-based sapphire cutting fluid is made from the following raw materials in parts by weight:

Abstract

The invention provides environment-friendly water-based sapphire cutting fluid. The cutting fluid comprises, by mass, 10-20% of dispersing agents, 3-8% of wetting agents, 6-12% of extreme pressure agents, 2-6% of organic acid, 6-10% of organic alkali, 0.02-2.0% of chelating agents, 0.01-1.0% of defoaming agents, 0.01-1.0% of antirust agents and 0.01-1.0% of sterilizing agents, wherein the dispersing agents are polyethylene glycol, the wetting agents are glycerin and / or lauric acid normal alcohol ester, the extreme pressure agents contain a boric acid ester compound and a polyether type nonionic surface active agent, and the antirust agents are benzotriazole and / or methyl benzotriazole. The environment-friendly water-based sapphire cutting fluid meets the production requirement and is low in cost, practical and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of sapphire cutting and cutting fluid, in particular to an environment-friendly water-based sapphire cutting fluid. Background technique [0002] In the process of cutting sapphire raw materials into mobile phone or watch mirrors, mobile phone cameras, mobile phone buttons, etc., due to the superhard and high-strength properties of sapphire, the relative speed of the processing tool on the sapphire needs to be as high as 20000-25000M / S, and the interface in the cutting area is instantaneous The temperature can reach 600-1000°C. Therefore, sapphire cutting fluid should have better lubrication, penetration, cooling, cleaning and rust prevention than glass cutting fluid. [0003] Traditional cold working cutting fluids, such as mineral oil cutting fluids, carbonate emulsified cutting fluids, etc., when processing sapphire, are prone to chipping and cracking of processed products, and these liquids are prone to...
