Low-skin-allergy synthetic metal cutting fluid and preparation method thereof

Abstract

The invention relates to a cutting fluid for metal working and a preparation method thereof, particularly a low-skin-allergy synthetic metal cutting fluid which comprises 1-10% of triethanolamine, 1-10% of monoethanolamine, 2-10% of decanedioic acid, 4-10% of dodecanedioic acid, 4-10% of octanoic acid, 3-8% of alkaline retaining agent, 0.1-1% of corrosion inhibitor, 5-10% of epoxyethane and epoxypropane nonionic surfactant, 0.5-1% of bactericide and the balance of water. The preparation method comprises the following steps: proportioning the raw materials of the cutting fluid in percentage by weight, adding the pure water, triethanolamine, monoethanolamine, decanedioic acid and dodecanedioic acid into a reaction kettle, continuously stirring for 30 minutes, adding the octanoic acid, alkaline retaining agent, corrosion inhibitor, epoxyethane and epoxypropane nonionic surfactant and bactericide, and continuously stirring for 30 minutes, thereby obtaining the low-skin-allergy synthetic metal cutting fluid. Compared with the prior art, the low-skin-allergy synthetic metal cutting fluid has the advantages of low skin allergy, low fog, favorable lubricating property, favorable dirty oil drainage property and lower irritation for skin of operators.

Description

[technical field] [0001] The invention relates to a cutting fluid for metal processing and a preparation method thereof, in particular to a synthetic metal cutting fluid with low skin allergy and a preparation method thereof. [Background technique] [0002] At present, the traditional metal cutting fluid produces a large amount of smoke and splashed oil foam during use, which will affect the health of the operators, especially the cutting fluid containing extreme pressure additives such as sulfur, phosphorus, and chlorine, which is easy to use The skin is dry, cracked, red and swollen, which induces a variety of skin diseases and brings potential hazards to the health of field operators. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned deficiencies and provide a kind of low skin allergy synthetic metal cutting fluid, which has good low skin allergy, low aerosolity and good lubricating and sewage oil performance, and r...
