Problems solved by technology

However, cutting fluids often become a source of hazards to occupational health and safety and environmental pollution during their use. Currently, there are several high-gloss cutting fluids commonly used in the market: oily cutting fluids, solvent-based cutting fluids, and emulsified cutting fluids. Problem: Oily cutting fluids are likely to cause dermatitis and respiratory damage to the operator; solvent-based cutting fluids are flammable and explosive; for water-soluble emulsified cutting fluids and other oily cutting fluids, they are composed of water, mineral oil and emulsifiers. It is characterized by good lubricating performance, but poor cooling, permeability, and stability, short service life, environmental protection problems when discharged, non-biodegradable, easy to produce mildew, odor, etc., and if the waste liquid is not passed through Effective treatment and direct discharge into rivers, rivers, seas, etc. will cause serious air pollution and water pollution, causing irreversible damage to the ecological environment
However, the water-soluble cutting fluid in the prior art does not have very ideal performance and effect in terms of service life, anti-embroidery, lubricity, and adaptability to different materials. For example, the Chinese patent application number 201010296416.4 discloses "a water-soluble Cutting fluid and its preparation method” has the advantages of long service life, good extreme pressure lubricity, rust resistance, cooling and cleaning properties, but its defoaming and hard water adaptability are not ideal, and its lubricity is not good The maximum no-jaw load value is not high enough

Abstract

The invention discloses a synthesized high-gloss cutting fluid for a smart phone frame. The cutting fluid comprises the following components in parts by weight: 10-20 parts of a rust inhibitor A, 3-8parts of a rust inhibitor B, 25-35 parts of a surfactant, 3-7 parts of a dispersing agent, 0.5-2 parts of a nonferrous metal corrosion inhibitor, 0.1-0.5 part of a settling agent, 0.2-0.8 part of an extreme pressure lubricant and the balance of water. The invention further provides a preparation method of the synthesized high-gloss cutting fluid. The cutting fluid provided by the invention is a water-based completely-transparent liquid, so that a clean environment of a processing site is guaranteed. Rapid defoaming can be finished within 5 seconds, and the processing state of a workpiece can be clearly observed during a using process, so that the product processing quality is guaranteed. Nano particles are selected as the extreme pressure lubricant, and a maximum non-seizure load value canbe up to 1380 N, so that the anti-friction and anti-wear performance of the cutting fluid is greatly improved. The hard water adaptability is up to 20000 ppm, and the dispersion characteristic of calcium soaps and magnesium soaps are achieved, so that the cutting fluid has extremely high hard water resistance. Long-term stability of lubricating performance and cleaning performance of the cuttingfluid is guaranteed, and the service life of the cutting fluid is prolonged.
