Problems solved by technology

[0007] Although the discrete pure cationic strip rolling fluid has the above advantages, its disadvantage is that its performance stability is very poor during the long-term use of the rolling mill. The aging of the product caused by the reaction will lead to a significant decrease in the cleaning performance of the discrete pure cationic strip rolling fluid after the product is used for 1-2 months, and the oil concentration feedback ability is significantly reduced, and its oil consumption is also significantly increased.

Abstract

The invention discloses a maintenance-free polymerized cation-containing metal rolling liquid in the field of rolling steel. The maintenance-free polymerized cation-containing metal rolling liquid comprises the following components in parts by weight: 80 to 90 parts of base oil, 1.0 to 5.0 parts of extreme pressure agent, 0.5 to 1.0 parts of antioxidant, 0.5 to 2.0 parts of emulsifier, and 0.5 to 1.5 parts of polymerized cation surfactant, wherein the molecular structure formula of the polymerized cation surfactants is shown in the specification, m is 10 to 25, and n is 5 to 18. The maintenance-free polymerized cation-containing metal rolling liquid has the technical effects of maintaining the high lubricity, high cleanliness and low oil consumption of the traditional cation metal rolling liquid, and also overcoming the defect that the traditional cation metal rolling liquid is easily aged in the long-time operation.

Description

technical field [0001] The invention relates to a maintenance-free metal rolling fluid containing polymerized cations and a preparation method. Background technique [0002] In recent years, with the rapid development of the national economy, the demand for high-strength steel sheets (HSS) for automobiles and the production of tinplate ultra-thin substrates (thickness less than 0.2mm) has increased sharply in the cold-rolled market. The rolling of high-strength steel plates and extremely thin tin plates places extremely high requirements on the lubricating and cleaning properties of the rolling fluid. [0003] At present, in order to meet the requirements of rolling high-strength steel plates and extremely thin tin plates, the mainstream rolling liquid technology products tend to develop towards the discrete pure cationic type. The so-called discrete pure cationic rolling liquid refers to the introduction of Monomer surfactants with cationic properties, such as one or more ...
