Abstract

The invention discloses a strong washing resistant waterproofing agent for textiles. The strong washing resistant waterproofing agent is prepared from the following raw materials in parts by weight: 10-20 parts of perfluorooctyl acrylate, 20-30 parts of n-butyl acrylate, 1-3 parts of fumed titanium dioxide, 10-15 parts of high-grade fatty alcohol acrylate, 1-4 parts of nekal, 2-5 parts of alkyl glyceryl ether sulfonate, 2-4 parts of polyether silicone oil, 1.5-3 parts of dimethylol urea, 0.5-1 part of zinc nitrate hexahydrate, 0.2 to 0.5 part of catalyst, and 100 to 140 parts of water. According to the invention, perfluorooctyl acrylate, n-butyl acrylate and high-grade fatty alcohol acrylate innovatively react in the presence of the catalyst, and fumed titanium dioxide, nekal, alkyl glyceryl ether sulfonate, polyether silicone oil, dimethylol urea and zinc nitrate hexahydrate are blended for reacting to obtain the waterproofing agent for textiles with good water and oil repellency andstrong washing resistance.

Description

technical field [0001] The invention relates to the field of textile processing materials and preparation, in particular to a strong washing-resistant textile waterproofing agent 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. The current disadvantages of water repellents for textiles are insufficient oil repellency and poor washing resistance, which limits their application in th...
