Problems solved by technology

However, for the aforementioned prior art scheme, the auxiliary substances added are not sufficiently mixed with the fluorine-containing water and oil repellent agent. On the premise of ensuring the water and oil repellent effect, the amount of auxiliary substances that can be added is less, and the use of fluorine-containing substances volume is still high

Embodiment 1

[0051] Take 15 grams of C 6 f 13 C 2 h 4 OCOCH=CH 2 , 10 grams of stearyl acrylate, 2 grams of lauryl acrylate, 1 gram of glycidyl acrylate, 1 gram of hydroxyethyl acrylate, 1 gram of acryloyloxyethyltrimethylammonium chloride, 10 grams of tetrapropylene glycol, 56.6 grams of water , 1 gram of octadecyltrimethylammonium chloride, 2 grams of stearyl polyoxyethylene (15) ether (abbreviated as OS-15) and 0.1 gram of acetic acid were mixed uniformly and emulsified at high speed for 20 minutes to obtain a pre-emulsion. The emulsification components do not include initiators, (modified) polyethylene wax emulsions and substances with a boiling point lower than the emulsification temperature; then the pre-emulsion is ultrasonically dispersed (high-pressure homogenization is also possible), and the pre-emulsion after ultrasonic dispersion is mixed with 40 grams ( Modified) Polyethylene wax emulsion (solid content 33%, non-ionic, softening point 130°C, particle size 90nm) mixed even...

Abstract

The invention provides a wax-containing water-and-oil repellent agent, preparation technology and application, wherein the wax-containing water-and-oil repellent agent comprises the following components in percentage by mass: fluoropolymer 20%-30%, (modified) polyethylene wax emulsion 3%-40%, surfactant 1-5%, hydrophilic solvent 4-20%, PH adjustment auxiliary agent 0.001-3% and water. The water-and-oil repellent agent provided by the invention has an excellent water-and-oil repelling effect, and an environmental protection property. In-situ polymerization technology is adopted in the invention; compared with prior art, the fluorine-containing material can play a better role of water-and-oil repelling, and the content of elemental fluorine in the decrease the water-and-oil repellent agent can be reduced.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a wax-containing water and oil repellent agent for textiles, a preparation method and application thereof. Background technique [0002] Many fields require textiles to have waterproof and oil-repellent performance, and the waterproof and oil-repellent effect is usually obtained by finishing with waterproof and oil-repellent agents. See "Printing and Dyeing", Volume 21, Issue 12, 1995, pages 37-41, in the paper on fluorine-containing water and oil repellent (Ⅰ): the mechanism of water and oil repellency, the author Kubo Motoshin proposed that water and oil repellents are generally Fluorine-containing (meth)acrylate monomers and long-chain alkyl (meth)acrylate fluorine-free monomers are the main raw materials, plus a small amount of other monomers are copolymerized. See "China Leather", Vol. 38, No. 9, pp. 52-57, 2009, in the paper New Progress in the Research of Fluorinated Ac...
