Abstract

The invention discloses a non-graphitic water-soluble lubricant used for plasticity working The lubricant comprises an alkali metal salt of m-phthalic acid, a water-soluble polymer and water. The used alkali metal salt of m-phthalic acid has a good lubricating performance in a strict warm or hot plasticity working environment. A condensate formed by combining crystals of the alkali metal salt of m-phthalic acid and the water-soluble polymer of alkali metal salt or fiber derivative of polymaleic acid resin adheres to the surface of a die and forms a lubricating film, and the lubricating film has a same strength with a high-temperature spray film formed by a graphite lubricant, is heatproof, hard and solid, and has a small friction coefficient, so the non-graphitic water-soluble lubricant can be used for the warm or hot plastic working of iron or aluminum alloy materials, makes the part processing quality good, contains no graphite, and can greatly improve the working environment.

Description

technical field [0001] The invention relates to the technical field of lubricants for metal temperature or thermal plastic processing, in particular to a non-graphite water-soluble lubricant for plastic processing and a preparation method. Background technique [0002] For a long time, the lubricants used for metal temperature or thermal plastic processing mainly include graphite lubricants made of graphite dispersed in water, oil lubricants such as mineral oil, and non-graphite lubricants. During the use of graphite lubricants, graphite powder is easy to scatter, easily pollute the environment, and cause damage to the health of workers; graphite is a good conductor of electricity, and graphite dispersed in the air is likely to cause electrical accidents; after treatment with graphite lubricants The surface of high-quality forgings is not easy to clean, and it takes a lot of manpower and material resources. The use of oil-based lubricants presents a fire hazard. Chinese pa...
