Aqueous cutting fluid for hard and brittle material multi-line cutting and preparation method thereof

Abstract

The invention discloses an aqueous cutting fluid for hard and brittle material multi-line cutting and a preparation method thereof. The aqueous cutting fluid comprises, by weight, 5-20% of ammonium carboxylate, 5-25% of a water-soluble lubricant, 10-20% of an antirust agent, 0.5-4% of a bactericide, 10-20% of a water-soluble anti-wear reagent at extreme pressure, 10-20% of triethanolamine, 0.1-4% of a settling agent, 0.01-0.1% of benzotriazole, 0.01-0.5% of an antifoaming agent and the balance water. The water-soluble lubricant is a mixture of poly(ether ester), glycerol and sulfurized fatty acid according to a weight ratio of (10-45): (3-18): (2-20). The cutting fluid has good integrated performances such as cooling performances, lubricity, settlement performances, defoaming performances, antirust properties and cleaning effects and satisfies hard and brittle difficult-to-cut material batch processing requirements of a multi-line cutting machine. The preparation method of the aqueous cutting fluid has simple processes, can be operated easily, realizes a low cost and can be finished at the normal temperature.

Description

technical field [0001] The invention relates to the technical field of cutting fluid and its preparation, in particular to an aqueous cutting fluid for multi-wire cutting of hard and brittle materials and a preparation method thereof. Background technique [0002] Hard, brittle and difficult-to-process new composite materials such as magnetic materials, sapphire, crystalline silicon, and special ceramics often need to be processed into sheets in batches by multi-wire cutting machines. The processing of traditional hard, brittle and difficult-to-machine composite materials generally adopts cooling and lubrication methods such as internal cutting special cutting oil, low-viscosity light oily cutting lubricant + SiC, mortar cutting, PEG cutting, etc. These old cooling and lubrication methods have long existed high Environmental pollution problems, for example, traditional internal cutting special cutting oils, such as Mold M6, Great Wall 00088, etc., have the problems of large ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a water-based cutting fluid for multi-wire cutting of hard and brittle materials and a preparation method thereof in view of the deficiencies in the prior art. Good lubricity, settling, defoaming, anti-rust and cleaning properties, which meet the batch processing requirements of multi-wire cutting machines for hard, brittle and difficult-to-process materials. When applied to multi-wire cutting machines, it can effectively reduce the number of workpieces The contact pressure between the cutting wires can reduce the broken wires of the cutting wires, improve the service life and processing efficiency of the cutting wires, and the surface finish of the processed workpieces is good. In addition, there is no irritating odor during processing, and there is no environmental pollution. problem, safe and environmentally friendly to use
