Abstract

The invention discloses a hydrophobic and oleophyllic bi-component acrylic resin and a preparation method and application thereof. The hydrophobic and oleophyllic bi-component acrylic resin comprises an A component and a B component, wherein the A component comprises 10 to 15 weight percent of hard monomer, 15 to 25 weight percent of higher alkyl methacrylates, 5 to 10 weight percent of fluorinated acrylic ester, 8 to 15 weight percent of cross linking monomer, 1 to 3 weigh percent of initiator, 10 to 25 weight percent of butyl acetate and 20 to 32 weight percent of dimethylbenzene; and the B component is an isocyanate curing agent of which the NCO content accounts for 10 to 23 percent of the total weight of the curing agent. The preparation method comprises a step of evenly mixing the A component with the B component which accounts for 14 to 32 weight percent of the A component to prepare the hydrophobic and oleophyllic bi-component acrylic resin. The bi-component acrylic resin has hydrophobic and oleophyllic performance and can serve as a coating for porous materials such as stainless steel metal meshes and filter paper to play a role in separating oil from water.

Description

technical field [0001] The invention relates to a functional acrylic resin, in particular to a hydrophobic and lipophilic two-component acrylic resin and a preparation method thereof. The acrylic resin can be used for oil-water separation. Background technique [0002] The wettability of the surface of the material can endow the material with many special functions. For example, the hydrophobic surface enables the material to have self-cleaning functions such as rain, snow, fog, and dust, while the lipophilic surface makes the material easy to be spread by oil, which is mainly used in oil exploration. And oil-water separation industry and other fields. Coating is the simplest and most direct way to change the wettability of the material surface. By coating a coating with special surface wettability, the wettability of the material surface can be directly changed. In coatings with special wettability, fluorine-containing acrylic resins are widely used. For example, the inte...
