[0050] Example 1

[0051] Take 15 grams of C 6 F 13 C 2 H 4 OCOCH=CH 2 , 10g octadecyl acrylate, 2g lauryl acrylate, 1g glycidyl acrylate, 1g hydroxyethyl acrylate, 1g acryloxyethyl trimethylammonium chloride, 10g tetrapropylene glycol, 56.6g water , 1 g of octadecyl trimethyl ammonium chloride, 2 g of stearyl alcohol polyoxyethylene (15) ether (abbreviated as OS-15) and 0.1 g of acetic acid are mixed uniformly, and emulsified at high speed for 20 minutes to obtain a pre-emulsion. The emulsification component does not include initiator, (modified) polyethylene wax emulsion and substances with 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 40 grams ( Modified) Polyethylene wax emulsion (solid content 33%, non-ionic, softening point 130°C, particle size 90nm), mix well and stir for 1 hour, then the initiator reacts, substan...

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...
