Problems solved by technology

The leveling agent used in traditional carbon steel plate leveling is often water or leveling liquid (aqueous product). However, this type of leveling agent has problems such as insufficient lubrication, broken belts, residual watermarks on the steel plate, and leveling liquid spots when leveling the steel plate. Even increasing the concentration of the product can not solve the above problems
[0004] In addition, in order to solve the defects caused by water-based products, most iron and steel enterprises currently use dry leveling agents to level steel plates. However, when dry leveling agents level steel plates, the pressure of leveling and rolling is high, which will cause poor shape and low processing accuracy of steel plates. , surface roughness, etc. cannot meet the requirements of customers, and at the same time, the post-process still needs to be coated with anti-rust oil products, resulting in increased production costs and longer production cycles

Abstract

The invention discloses flattening antirust oil for cold-rolled steel plates and a preparation method thereof; the flattening antirust oil is made from, by weight, 300-500 parts of trimethylolpropane oleate, 200-400 parts of a multi-effect antirust agent, 10-30 parts of alcohol ethoxylate-9, 450-650 parts of paraffin-based basic oil, 40-60 parts of vulcanized olefin cottonseed oil, 10-30 parts of polyisobutene, and 5-10 parts of an antioxidant. The flattening antirust oil has good lubricating property and antirust property, and can be applied to a flattening process to reduce surface roughness of cold-rolled steel plates, reduce rolling pressure and shorten production cycle.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and more specifically relates to a leveling antirust oil for cold-rolled steel plates and a preparation method thereof. Background technique [0002] With the development of electronic products, it is necessary to replace some materials with good electrical conductivity with alloy materials or coating materials. However, the current level of technology and processing methods cannot meet the production needs. [0003] The leveling of plain carbon steel plate is an important link in metal processing. The leveling agent used in traditional carbon steel plate leveling is often water or leveling liquid (aqueous product). However, this type of leveling agent has problems such as insufficient lubrication, broken belts, residual watermarks on the steel plate, and leveling liquid spots when leveling the steel plate. It is to improve the use concentration of the product and cannot solve the abo...
