Polyethylene glycol bisalkenyl succinate monoalkyl ester and preparation method thereof

Abstract

Polyethylene glycol bisalkenyl succinate monoalkyl esters comprising the following ingredients: alkenyl maleic anhydride of a suitable alkyl group, an alkyl fatty alcohol, polyethylene glycol of a suitable degree of polymerization, a catalyst, a suitable alkyl Alkenyl maleic anhydride and alkyl fatty alcohol react under the action of catalyst to generate alkenyl succinic acid monoalkyl ester, alkenyl succinic acid monoalkyl ester and polyethylene glycol with appropriate degree of polymerization , The reaction gives polyethylene glycol double alkenyl succinic acid monoalkyl ester. The present invention adopts a specific chemical molecular structure to make it have excellent emulsifying properties, and adjusts the ratio of the general-purpose low-molecular emulsifier and the invented high-molecular emulsifier to be used together to control the produced steel plate rolling oil. The diameter of the emulsion particles can be adjusted, and the required stable lubricating performance can be maintained during the steel rolling process. It has low oil coke formation tendency and good steel plate post-rolling annealing cleanliness, and solves the problem of complex rolling oil formulation. The invention is used in the field of steel plate rolling.

Description

technical field [0001] The invention relates to the field of steel plate rolling oil, in particular to a steel plate rolling oil emulsification additive polyethylene glycol bisalkenyl succinate monoalkyl ester having emulsifying performance and capable of stabilizing the particle size of the emulsified liquid and a preparation method thereof. Background technique [0002] The present invention relates to a lubricating oil additive for cold rolling steel sheets and strips. When cold-rolling steel plates, it must go through various processes such as pickling-cold rolling-cleaning-annealing-levelling-inspection. The composition of general steel plate cold rolling oil is based on grease, mineral oil or fatty acid synthetic fat, etc., adding various emulsifiers, antirust agents, extreme pressure agents, lubricants, oily agents, antioxidants and other additives. into an oil-in-water emulsion. Usually used at a concentration of 1-20%, it can play a lubricating role to prevent the...
