Embodiment 1

[0046] After mixing 9w% triethanolamine, 5w% monoethanolamine and 40w% water, add 5w% chlorinated paraffin, 10w% fatty alcohol polyoxyethylene ether (brand AEO-10), 5w% petroleum sulfonate sodium nitrate, 15w% oleic acid, 5w% pentaerythritol tetralaurate, 5w% mineral oil, 0.5w% benzotriazole, 0.5w% methyl silicone oil, stirred at 60°C for 30 Minutes, until completely transparent, no sediment, that is, the cutting fluid A (referring to the cutting fluid stock solution, the same as the following examples).

Embodiment 2

[0048] After mixing 21w% of triethanolamine, 3w% of monoethanolamine and 35w% of water, add 7w% of chlorinated paraffin, 5w% of fatty alcohol polyoxyethylene ether (AEO-10), 8w% of octanoic acid, 10w % oleic acid, 5w% pentaerythritol tetralaurate, 5.6w% mineral oil, 0.2w% benzotriazole, 0.2w% methyl silicone oil, stirred at a temperature of 60°C for 40 minutes until Completely transparent, no sediment, that is, the cutting fluid B is prepared.

Embodiment 3

[0050] After mixing 15w% triethanolamine, 4w% monoethanolamine and 38w% water, add 5w% chlorinated paraffin, 10w% fatty alcohol polyoxyethylene ether (AEO-10), 5w% dodecene Succinic acid, 15w% oleic acid, 2w% trimethylolpropane trilaurate, 5.2w% mineral oil, 0.5w% benzotriazole, 0.3w% methyl silicone oil, in Stir at a temperature of 55°C for 30 minutes until it is completely transparent and free of sediment, and the cutting fluid C is obtained.

Abstract

The invention disclose a micro-emulsification type stainless steel cutting fluid belonging to metal-cutting lubricant technical field to solve the problems that the existing cutting fluid can not be commendably used in cutting process of stainless steel and can endanger the health of the workers. The micro-emulsification type stainless steel cutting fluid comprises 20-40 wt% water, 5-20 wt% paraffin base mineral oil or naphthenic base mineral oil, 1-15 wt% non-ionic surfactant of alkyl phenol polyoxyethylene ether or fatty alcohol polyoxyethylene ether, 5-10 wt% chloroparaffin, 1-10 wt% petroleum sodium sulphonate and hardship or alkenyl succinic acid rust preventive, 5-25 wt% mixing alkyol amine of mono ethanolamine and trieanolamine, 5-15 wt% oleic acid, 2-10 wt% polyatomic alcohol lauric acid ester or polyatomic alcohol oleic acid ester, 0.1-0.5 wt%.benzotriazole, and 0.1-0.5 wt% methyl silicone oil anti-foam agent. The micro-emulsification type stainless steel cutting fluid is specially used in the cutting process of the stainless steel.

Description

technical field [0001] The invention belongs to the technical field of metal cutting lubricants, and relates to a microemulsion type stainless steel cutting fluid. Background technique [0002] Stainless steel cutting fluids generally include water-based cutting fluids and oil-based cutting fluids. Affected by the environment, the use of oil-based cutting fluids has been decreasing in recent years, and water-based cutting fluids are developing rapidly. Water-based cutting fluid includes three types: emulsified, fully synthetic, and microemulsified. [0003] There are many types of cutting fluids at home and abroad. Cutting fluid as described in CN1142529A, adopts kerosene, machine oil, chlorinated paraffin, emulsifier, swire oil, polyethylene glycol, antirust composition (comprising water, sodium benzoate, sodium nitrite, triethanolamine) etc. to form. This cutting fluid has a certain cutting and anti-rust effect, but because it contains sodium nitrite, it will cause canc...
