Problems solved by technology

This application introduces POSS bases into traditional polymers to prepare hydrophobic, amphiphilic, and hydrophobic and oleophobic coatings respectively. However, there is no literature report on the application of POSS-based fluoropolymers to metal filters to construct micro-nano dual-scale composite rough structures. To achieve the effect of superhydrophobic and superoilophilic, so as to realize the efficient separation of oil and water and the efficient transportation of oil

Abstract

The invention discloses a POSS (Polyhedral Oligomeric Silsesquioxane) based hybridized fluorinated acrylate resin, and a preparation method and an application thereof. The formula of the resin comprises the following components by weight percent: 0.9-14% of POSS based monomer, 1.5-10% of hard monomer, 2.5-14% of soft monomer, 4-10.5% of acrylic higher ester monomer, 1.8-6% of fluoridized acrylate monomer, 1.8-9% of cross-linked monomer, 0.4-1.5% of initiator and 50-80% of solvent. According to the invention, the acrylic higher ester monomer is introduced as an oleophilic monomer into a fluorinated acrylate copolymer and then a hydrophobic and oleophilic compound multi-scale structure is established on filter paper or a metal filter screen by virtue of aggregating self-assembly of the POSS base in the copolymer; therefore, a hydrophobic and oleophilic coating is prepared. The resin coating prepared from the resin provided by the invention is applicable to the oil-water separation field and capable of removing trace moisture in the fuel oil, and has great practical application significance.

Description

technical field [0001] The invention relates to an acrylate resin, in particular to a POSS-based hybrid fluorine-containing acrylate resin with superhydrophobic and superlipophilic properties, its preparation method and application; it belongs to organic / inorganic hybrid materials. Background technique [0002] With the development of aviation and automobile industries, people have higher and higher requirements for aircraft and automobile engines. As the "blood" of the engine - fuel and hydraulic oil, their quality directly affects the performance of the engine. Oil water content is an important indicator of oil quality and one of the main causes of engine failure. The filter in the engine uses coalescence separation to remove impurities such as particles and water in the oil. It is of great practical significance to select a filter screen (filter paper) with good hydrophilic and oleophobic properties to separate the water in the oil. [0003] In recent years, the research...
