Fabric fluoride-free waterproof agent and preparation method thereof

Abstract

The invention discloses a fabric fluoride-free waterproof agent which consists of the following raw materials in parts by weight: 20-30 parts of n-butyl acrylate, 1-3 parts of gas-phase titanium dioxide, 10-15 parts of high-class higher aliphatic alcohol acrylate, 1-3 parts of polyethylene wax, 1-4 parts of naphthalene sulfonicacid dibutyl-sodium salt, 2-5 parts of alkyl glyceryl ether sulfonate,2-4 parts of polyether silicon oil, 1.5-3 parts of stearic acid, 0.5-1 part of zinc nitrate hexahydrate, 0.2-0.5 part of a catalyst and 100-140 parts of water. By adopting the fabric fluoride-free waterproof agent disclosed by the invention, the n-butyl acrylate and the high-class higher aliphatic alcohol acrylate are creatively reacted under the function of the catalyst, and are subjected to commixing reactions with the gas-phase titanium dioxide, the polyethylene wax, the naphthalene sulfonicacid dibutyl-sodium salt, the alkyl glyceryl ether sulfonate, the polyether silicon oil, the stearicacid and the zinc nitrate hexahydrate, then a good waterproof and anti-oil effect can be achieved, and meanwhile an environmental-friendly fluoride-free waterproof finishing agent which is good in washing resistance for fabrics can be prepared.

Description

technical field [0001] The invention relates to the field of textile processing materials and preparation, in particular to a fluorine-free waterproofing agent for textiles and a preparation method thereof. Background technique [0002] In order to meet people's continuous requirements for textiles, more and more textiles are endowed with functionality, and waterproof function is one of the important branches. Water and oil repellent fabric is a functional and intelligent fabric. Textiles treated with water and oil repellency can resist rainwater and oil stains, and can discharge sweat and sweat from the human body in a timely manner, so as to keep the human body dry and warm, and are water and oil repellent in decoration and industrial fields. Functional tablecloths, car protective covers, etc. are also popular. [0003] At present, the best waterproof finishing agents are still fluorine-containing organic polymers. Of course, most of these waterproof finishing agents co...

AI Technical Summary

Problems solved by technology

With the further improvement of people's requirements for the safety of textiles and chemicals, environmentally friendly fluorine-free waterproofing agents will become more and more popular, but the disadvantages of the existing fluorine-free environmentally friendly waterproofing agents are oil-proof performance and waterproof and washing resistance. Insufficient, far from reaching the effect of fluorine-based products, thus limiting its development and application in the textile field to a certain extent
