Abstract

Disclosed is a microemulsifying metal-cutting-fluid composition, comprising base oil or oily agent, mixed alcohol-amine, boric acid, anionic surfactant, nonionic surfactant, antirust agent, copper alloy corrosion inhibitor, preservative, deionized water and the like. The invention has the advantages of excellent lubricity, cooling ability, cleaning ability and a long lifetime of metal cutting fluid, being suited to various metal processing technologies such as cutting, reaming, boring, grinding. Also, the wastewater is easy to treat.

Description

technical field [0001] The invention relates to metal cutting lubrication technology, in particular to composition components of microemulsion semi-synthetic metal cutting fluid. Background technique [0002] Microemulsion semi-synthetic metal cutting fluid is a kind of water-based cutting fluid, which has excellent lubricity, extreme pressure and anti-wear properties, cleaning performance, corrosion resistance, long life, etc. Microemulsion semi-synthetic metalworking fluids have excellent performance in various processing conditions such as grinding and grinding, and have been more and more widely used. For different processing materials (such as cast iron, carbon steel, magnesium-aluminum alloy, nickel alloy, etc.), processing conditions (such as turning, drilling, grinding, etc.), processing technology (such as line speed, feed rate, etc.), there will be corresponding Highly targeted semi-synthetic metalworking fluid products to meet the lubrication and cooling requirem...
