Abstract

The invention discloses graphene oxide-containing water-based metal cutting fluid and a preparation method thereof. The graphene oxide containing water-based metal cutting fluid consists of a lubricating additive, an anti-rusting agent, a defoaming agent, benzotriazole, triethanolamine oleate, ethanol amine and water. The contents of the raw materials are as follows in percentage by weight: 0.5-5% of the lubricating additive, 30-40% of the anti-rusting agent, 0.4-0.6% of the defoaming agent, 0.2-0.4% of the benzotriazole, 2-4.5% of a detergent, 1-2% of ethanol amine and the balance water, wherein the lubricating additive is a graphene oxide dispersion liquid. The graphene oxide-containing water-based metal cutting fluid has the beneficial effects that due to addition of a graphene oxide additive, not only are properties of the cutting fluid improved, such as the lubrication property, the anti-wearing property and the cooling property, but also graphene oxide has slight environment influence and is beneficial to environmental protection.

Description

technical field

[0001] The invention relates to the technical field of metal processing, in particular to a water-based metal cutting fluid containing graphene oxide and a preparation method thereof. Background technique

[0002] Cutting fluid is a mixed lubricant used to lubricate and cool machining tools and machined components during metal cutting. According to the different media, it can be divided into oil-based and water-based. Among them, oil-based cutting fluid is widely used in the field of metal processing due to its good lubricity and rust resistance, but its biodegradability is too poor to last for a long time. It exists in the environment, which has a serious impact on biology and ecology; water-based cutting fluid has good cooling and cleaning performance, low cost, no pollution, and meets the requirements of sustainable development. Now it is gradually replacing traditional oil Basic cutting fluid. However, water-based cutting fluid also has many defects, su...
