Abstract

The invention provides a high-property water-based emulsion cutting fluid composite, belonging to the field of metalworking fluid products. The composite is a water soluble product and comprises mineral oil, pentaerythritol fatty acid synthetic esters, a compound acidamide anti-rusting agent, an emulsifier, a corrosion inhibitor, a sulfide aliphatic acid ester extreme pressure lubricant, a bactericide and a defoamer; wherein, the compound acidamide anti-rusting agent is the composite of a component A, namely polycarboxylic acid hydramine acidamide and a component B, namely a mixture of triazole and a cosolvent butyl ether diglycol, thereby obviously improving the anti-rusting property of the product and broadening the anti-rusting applicability of diverse metals. The components of the composite product of the invention are scientific and reasonable in selection and use and balanced and harmonious in proportioning, thus achieving the effects of complementary action and synergy, therefore, the water-based emulsion cutting fluid of the invention not only enjoys high lubricating property, high anti-rusting property, high emulsibility, high antibacterial ability and high stability and has long service life, but also produces no pollution to the environment, does no harm to human bodies and satisfies the requirements of high-difficulty machining on the cutting fluid.

Description

technical field [0001] The invention discloses a high-performance water-based emulsified cutting fluid composition, which belongs to the field of metal processing fluid products, and in particular relates to machine tool cutting fluid products. Background technique [0002] Cutting fluids in the traditional sense mainly include oil-based cutting fluids and water-based cutting fluids. Starting from the use of water and animal and vegetable oils, they have a long history of development in machining and are widely used. Water-based cutting fluid is characterized by fast heat dissipation and low cost. Water-based cutting fluid is divided into three categories: emulsion (Solubleoil), synthetic cutting fluid (Synthetics) and semi-synthetic cutting fluid (Semi-synthetics). [0003] The classic emulsified cutting fluid is composed of emulsified oil, emulsifier, antirust agent and water. The emulsified oil used is mineral oil with a content of up to 80%. Sodium nitrate, this kind o...
