Abstract

The invention provides an environment-friendly super-hydrophobic oil-resistant surface treating agent for a textile. The surface treating agent mainly comprises the following raw materials by weight: 1 to 15 parts of a fluorine-containing compound, 1 to 5 parts of a silicon-containing compound, 1 to 15 parts of a fluorine-silicon copolymer, 0.5 to 5 parts of a silane coupling agent and 50 to 95 parts of a solvent. The surface treating agent is prepared by subjecting the above-mentioned raw materials to a reaction at 5 to 45 DEG C for 0.5 to 3 h. The surface treating agent has good hydrophobicity to the textile. The invention has the following advantages: the synthetic method for the surface treating agent is simple and is convenient for large-scale production; the surface treating agent can endow the textile with super-hydrophobicity, oil resistance and antifouling property; the surface treating agent is environment-friendly and does not contain perfluorocapylic acid (PFOA) and perfluorooctane sulfonate (PFOS) compounds; the surface treating agent is simple and convenient to use and applicable to manners like spraying, dip-coating and brush coating; the surface treating agent has a fast drying speed, can be used at room temperature and is free of requirements for special treatment; and the surface treating agent is applicable to a textile made of cotton, hemp, wool, silk, pile, fiber, leather or the like.

Description

technical field [0001] The invention relates to a superhydrophobic and oil-repellent surface treatment agent for environment-friendly textiles, a synthesis method and application. Background technique [0002] The free energy of the material surface determines whether the material is hydrophilic or hydrophobic. The lower the free energy, the stronger the hydrophobicity; the microscopic roughness of the surface determines the strength of hydrophilicity and hydrophobicity. The rougher the surface, the stronger the hydrophobicity. Water is a substance with relatively high surface energy, so substances with lower surface energy than water, such as some substances containing silicon and fluorine, will show hydrophobicity, and water will shrink into a spherical shape on the surface of such substances. Since super-hydrophobic materials have many unique surface properties, such as waterproof, oil-proof, anti-fouling, snow-proof, anti-corrosion and self-cleaning and super-hydrophobic...
