Problems solved by technology

Chinese patent CN1100750A discloses a lubricant dry powder for metal thermoplastic processing. When this product is used, it needs to be prepared into a suspension with a certain proportion of water. Because the dispersion effect is poor and unstable, the prepared suspension has a short storage time and needs to be prepared. On-site preparation and immediate use, so few companies use it
The disadvantages of the product of this invention are poor dispersion and stabilization effect, uneven and dense film formation, and poor water erosion resistance

Abstract

The water plumbago mandril lubricant which applies to metal thermoplastic processing, especially applies to roller mandril uses plumbago powder as lubricant, uses compound resin latex as film agent, uses borax or tripoly sodium phosphate as antioxidant, hexa sodium phosphate as dispersant, natrium stearate calcium soap as stabilizing agent, phosphate butyl tri-ester as antifoam, carboxyl ethyl fibrin as thick-increasing agent, 1,2-propyl diethanol as film assistant agent, the residual is water.

Description

technical field [0001] A lubricant suitable for thermoplastic processing of metals, especially for continuous rolling tube mandrel rods. Background technique [0002] Mandrel lubricant is mainly an important process consumable material for continuous rolling mills in iron and steel enterprises. Since the long mandrel is in the steel pipe with a high temperature above 900°C, and under the condition of extremely high rolling pressure, it will have a large relative sliding with the steel pipe, so the high-performance mandrel lubricant is the key to whether the unit can vital factor for normal production. Chinese patent CN1100750A discloses a lubricant dry powder for metal thermoplastic processing. When this product is used, it needs to be prepared into a suspension with a certain proportion of water. Because the dispersion effect is poor and unstable, the prepared suspension has a short storage time and needs to be prepared. It is formulated on-site and ...
