Problems solved by technology

However, the water-soluble emulsified cutting oil currently available on the market has unsatisfactory lubricity (at 5% concentration, the tapping torque value is above 2100 N.cm, and the reaming surface roughness Ra value is above 0.7 μm); the permeability is poor (When the concentration is 5% and the particle size of iron powder is 100 mesh, the permeability test time is more than 60s); the formula contains harmful substances that are harmful to health; during the processing, the droplets of the diluent pollute the working environment, and the droplets are not volatile after drying Ingredients cause mechanical stickiness

Abstract

The invention discloses an environment-friendly emulsion cutting oil with high lubricity and high permeability for metal working. The emulsion cutting oil is composed of a polymer carboxylic acid, an amine, a surfactant, mineral oil, a synthetic lubricant, a defoamer and an anti-corrosive agent. The emulsion cutting oil disclosed by the invention causes small pollution during processing, has excellent lubricity and permeability, and is safe to human and environment.

Description

technical field [0001] The invention relates to an emulsified cutting oil used in metal processing. Background technique [0002] For a long time, the processing oils widely used in metal cutting and grinding processing are basically based on mineral oils, which are divided into two categories: non-water-soluble cutting oils and water-soluble emulsified cutting oils. Since non-water-soluble cutting oil has many disadvantages such as smoke, oil mist, easy to catch fire, and difficult to clean the processed parts, it is gradually being replaced by water-soluble emulsified oil with excellent processing performance, cooling performance, sanitation and safety performance. However, the water-soluble emulsified cutting oil currently available on the market has unsatisfactory lubricity (at 5% concentration, the tapping torque value is above 2100 N.cm, and the reaming surface roughness Ra value is above 0.7 μm); the permeability is poor (When the concentration is 5% and the particle...
