Abstract

The present invention relates to chemically synthesized assistant for metal cutting, and is especially one kind of water-base cutting fluid with cooling, rust-preventing, cleaning and lubricating functions. The present invention is obtained through mixing antirust agent, surfactant, lubricant and other metal machining assistants at certain condition. Specifically, the water-base cutting fluid contains p-tert-butyl benzoic acid 1-3 wt%, benzoic acid 2-5 wt%, boric acid 2-4 wt%, ethanolamine 2-8 wt%, polyethylene glycol of molecular weight 400-600 4-8 wt%, benzotriazole 0.1-0.5 wt%, non-ionic polyacrylamide 0.05-0.2 wt%, and water for the rest. The water-base cutting fluid has excellent abrasion dust settleability, no stickness to grinding wheel, excellent antirust performance, excellent cooling performance, good lubricating performance, environment friendship, etc.

Description

technical field [0001] The invention belongs to a chemical synthesis additive used in the technical field of metal cutting, a water-based cutting fluid with cooling, antirust, cleaning and lubricating functions and a preparation method thereof. Background technique [0002] According to the national standard GB6144-85, cutting fluids are divided into four categories: Class I is suitable for rough grinding and rough machining; Class II anti-rust type is suitable for high anti-rust performance; Class III extreme pressure type is suitable for heavy duty of various machine tools Cutting and powerful grinding; Class IV is suitable for cutting and grinding of various metals (ferrous metals, copper, aluminum, etc.), as well as extreme pressure cutting or precision cutting. The present invention relates to type II. The existing traditional coolant, also known as saponified oil, is composed of mineral oil and emulsifier, which not only causes a great loss of energy, increases a lot ...
