Embodiment Construction

[0007] 1. Preparation of sand mill particle slurry: 20%-30% of calcined natural flake graphite containing particle size below 10um, 2% of grinding aid tannin, 3% of dispersant NNO, a little ammonia water and 65% of pure water 75% of the slurry is ground in a vertical stirring mill for 48 hours. During the grinding process, the jacket keeps circulating cooling water. The slurry will remove most of the impurity iron through a circulating pump and a permanent magnet iron remover. After grinding, it will be discharged into graphite particles Slurry, 95% of its particle size should be below 200nm.

Abstract

The invention discloses a multipurpose processing liquid of water-based nanometer flake graphite, wherein the metal processing liquid uses the natural nanometer flake graphite; due to the waterborne property, the flake graphite has excellent lubricity, conductivity of electricity and heat and high temperature stability; therefore, the metal processing liquid has excellent lubrication property, cooling property, extreme pressure anti-wear property (high temperature stability), environmental protection, and prevents static electricity; the metal processing liquid shall be used for refined and high speed metal cutting process, metal grinding process and metal drawing process and the like via proper regulation. The metal processing liquid is a water-based metal processing liquid which has environmental protection, excellent properties and wide use.

Description

technical field [0001] The invention relates to the technical field of metal processing aids, in particular to a water-based nano-scale graphite multipurpose processing fluid. Background technique [0002] With the development of machining technology, the demand for metalworking fluids has increased rapidly, and the requirements for various indicators, especially the lubrication function, cooling function and high temperature stability, are also getting higher and higher. Traditional metalworking fluids are divided into two categories: solvent-based and water-based. Solvent-based metalworking fluids have better lubricity, but poor cooling performance and greater impact on the environment; water-based metalworking fluids have better cooling performance. However, the lubricating performance is often not up to the requirement. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a water-based na...
