Water-based cutting fluid for vermicular cast iron processing, and dilution solution thereof

Abstract

The present invention discloses a water-based cutting fluid for vermicular cast iron processing, and a dilution solution thereof. The water based cutting fluid comprises 3-10% of an anti-rust additive, 4-10% of fatty acid amide, 2-3% of organic amine, 3-10% of long-chain fatty acid, 2-5% of fatty alcohol polyoxyethylene ether, 5-8% of petroleum sodium sulfonate, 1-5% of a coupling agent, 10-15% of an extreme pressure additive, 15-20% of a synthetic ester, 1-2% of a sterilization agent, 0.5-1.0% of an anti-forming agent, and 32-45% of water, wherein the anti-rust additive is a boric acid anti-rust additive and dicarboxylic acid, and the coupling agent is a fatty alcohol and / or aliphatic ether. The water-based cutting fluid of the present invention has characteristics of good lubrication performance, good cooling performance, good anti-rust property, no chlorine, diamine, nitrite and other nitro compounds, no environmental pollution, no irritating odor, easy cutting, easy powder settlement, and effective cutter service life prolonging.

Description

technical field [0001] The invention relates to a water-based cutting fluid for processing vermicular graphite cast iron and its dilution fluid. Background technique [0002] my country began to study vermicular graphite cast iron in the 1960s, and it has been successfully studied and put into use effectively. Compared to gray iron or aluminum, CGI has 75% higher tensile strength, 40% higher modulus of elasticity, and 100% higher fatigue strength. In addition, the growth resistance and oxidation resistance of compacted graphite cast iron are higher than those of other cast irons, so it is widely used in the production of automobile engines. [0003] However, since the wear resistance of compacted graphite cast iron is higher than that of ordinary cast iron, it causes the characteristics that compacted graphite cast iron is difficult to process. The processing power required to process vermicular graphite cast iron is about 15% to 25% higher than that of gray iron. Even du...
