Abstract

The present invention provides a multi-layer oil-water separation material, comprising at least a coalescing layer 1 and a coalescing layer 2, wherein the coalescing layer is a mixed layer of hydrophilic-hydrophobic fibers, including hydrophilic fibers and selected from hydrophobic fibers and adhesive fibers One or more of the fibers, the coalescing layer 2 is a hydrophobic fiber layer, including one or more of hydrophobic fibers and adhesive fibers. The present invention also provides the preparation method and application of the multilayer oil-water separation material. The multi-layer oil-water separation material provided by the present invention has high separation efficiency, low filtration resistance, strong efficiency stability, wide raw material sources and moderate thickness, and is suitable for industrialized large-scale production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials and filter materials, and in particular relates to a high-efficiency multi-layer oil-water separation material and a preparation method and application thereof. Background technique [0002] The moisture in diesel will reduce the combustion, lubrication, safety and other properties of diesel, cause corrosion and blockage of engine parts, and increase the content of harmful substances in the exhaust gas after combustion, so removing the moisture in diesel is important for the normal operation of the engine and environmental protection. very important. The oil-water separation filter can effectively remove the water in the diesel oil, and the oil-water separation material is the core component that determines the oil-water separation performance of the filter. Traditional oil-water separation materials have two forms: pre-filtered oil-water separation materials and high-efficiency oil-wat...
