Abstract

The invention relates to a fluorine-containing modified vegetable oil polymer water-repellent finishing agent, and preparation and an application thereof. The water-repellent finishing agent is obtained after a mixture is polymerized with styrene, wherein the mixture is composed of esters; the esters are generated from a reaction between fatty acid and CF3-(CF2)m-CH2OH or CF2H-(CF2)m-CH2OH; and the fatty acid is obtained by hydrolyzing vegetable oil. A preparation method of the water-repellent finishing agent comprises the following steps: (1) hydrolyzing the vegetable oil, thereby obtaining fatty acid sodium; (2) acidizing the fatty acid sodium, thereby obtaining higher fatty acid; (3) performing esterification on the higher fatty acid and fluorine-containing alcohol, thereby obtaining a fluorine-containing ester; and (4) adding the fluorine-containing ester to the styrene, thereby obtaining the water-repellent finishing agent. The water-repellent finishing agent provided by the invention is applied to the water-repellent finishing for cellulose fibers and blend fabrics thereof. The water-repellent finishing agent provided by the invention is free from obvious influence on air permeability, whiteness and breaking strength of the cellulose fibers. The water-repellent finishing agent provided by the invention has the advantages that a synthesizing process is simple, the cost is low, and raw materials are environment-friendly and cause less environmental pollution.

Description

technical field [0001] The invention belongs to the field of fluorine-containing water-repellent finishing agent and its preparation and application, and in particular relates to a fluorine-containing modified vegetable oil polymer water-repellent finishing agent and its preparation and application. Background technique [0002] Water-repellent finishing is an important aspect of functional finishing. With the continuous advancement of science and technology, new fabric water-repellent finishing technologies are constantly being adopted by people, and metal soaps, metal complexes, pyridines, methylol compounds, and organosilicon finishing agents have been used as finishing agents for fabrics. Water-repellent finish. [0003] However, the previous water-repellent finishing agents are gradually eliminated due to the adverse effects on fabric feel, air permeability, whiteness, poor durability and environmental factors, so people began to use low surface energy organic fluorine...
