Abstract

The invention discloses a fluorine-containing acrylic superhydrophobic resin for oil-water separation and a preparation method thereof. The superhydrophobic resin passes raw materials such as hard monomers, soft monomers, fluorine-containing functional monomers, organic bentonite and fullerene through a solution. Prepared by free radical polymerization. The reaction process of the present invention is simple and the production cost is low. The performance of the fluorine-containing acrylic superhydrophobic resin prepared by the present invention is stable and meets the requirements of various technical indicators; its superhydrophobicity, aging resistance, high temperature and low temperature resistance and other performances are quite excellent. It has excellent oil-water separation performance, meets the application requirements of the separation filter element of the automobile engine filter, can effectively remove various water in the oil, and can be widely used in the separation filter element of the automobile.

Description

【Technical field】 [0001] The invention relates to a fluorine-containing acrylic superhydrophobic resin and a preparation method thereof, in particular to a fluorine-containing acrylic superhydrophobic resin for oil-water separation of automobile engine filters and a preparation method thereof. 【Background technique】 [0002] As relevant environmental protection policies and regulations have stricter requirements on exhaust emissions, automobiles have higher and higher requirements on the quality of fuel. Fuel is used as fuel for automobiles, and its quality directly affects the working conditions and service life of engines and automobiles. However, a small amount of water occasionally exists in various oils used in automobiles, and the polluted water in these oils exists in three forms: dissolved water, free water and emulsified water. Among them, emulsified water is tiny water droplets in suspension evenly dispersed in oil, and the particle size is generally in the range ...
