Problems solved by technology

The commonly used poly-a-olefin type pour point depressant products in China, when the pour point depressant molecules are co-crystallized with wax molecules, lack a certain polar adsorption capacity, and cannot well meet the requirements of low-temperature performance of high-grade lubricating oil. Pour point depressant products will inevitably increase the cost of use

Abstract

The invention relates to a preparation method for a fumarate copolymer pour point depressant for lubricating oil. The method mainly comprises the following steps: selecting fumaric acid, a higher alcohol (carbon number 8-18), vinyl acetate, styrene, toluene, and benzoyl peroxide (BPO), wherein the fumaric acid and the higher alcohol (carbon number 8-18) are analytical reagents and purchased froma Tianjin Guangfu fine chemical research institute; the vinyl acetate, the styrene and the toluene are analytical reagents and purchased from a Beijing chemical work; and the benzoyl peroxide (BPO) isan analytical reagent. According to the invention, the fumarate copolymer pour point depressant for the lubricating oil prepared by the method has excellent pour point depressing performance in a plurality of base oil, and is a novel pour point depressant with excellent performance for the lubricating oil, and has higher application value and broad market prospects.

Description

technical field [0001] The invention relates to a preparation method of a fumarate copolymer lubricating oil pour point depressant. Background technique [0002] Energy conservation and environmental protection are major strategies for the sustainable development of the global economy and society in this century. Excessive energy consumption has caused more and more serious environmental problems. Using suitable lubricating oil is an important and effective method to reduce automobile exhaust emissions and save fuel. With the continuous development of the machinery industry, the requirements for the performance of lubricating oil continue to increase. As an additive to improve the pour point of oil products, pour point depressants play a very important role in lubricating oil. In the history of nearly a hundred years since the first application for the patent of pour point depressant by human beings, condensation products of chlorinated paraffin and phenol, polymethacrylate...
