Problems solved by technology

The functional monomer forms a short side chain with a reactive group on the main chain of the waterproofing agent, and the reaction of the reactive group forms a strong constraint on the main chain, forming a hard hand feeling; Resistance, many reactive groups are self-crosslinked, do not form a strong bond with the fabric, and the durability improvement is not obvious

Embodiment 1

[0056] Get 11 grams of perfluorohexylethyl methacrylate, 1 gram of fluorine-containing monomer B (by 2mol of perfluorohexylethyl alcohol, 1mol of hexamethylene diisocyanate (HDI) trimer and 1mol of hydroxybutyl acrylate reaction), 10.4 g behenyl acrylate, 2 g styrene, 2 g telechelic polymer B, 5.7 g dipropylene glycol ether, 5 g Ethoqual C / 25 (ethoxylated quaternary ammonium salt), 0.3 g acetic acid , 58.8 grams of water, heated up to 55 degrees, and emulsified at high speed for 60 minutes to obtain a pre-emulsion; then nitrogen gas was passed for 30 minutes, and the temperature was controlled at 62 degrees Celsius. Add 0.2 g of azobisisobutylamidine hydrochloride and 3.6 g of vinyl chloride, and keep the reaction for 8 hours. Finally, lower the temperature of the system to room temperature and filter through a 300-mesh filter cloth to obtain the water and oil repellent.

Abstract

The invention discloses a high-efficiency water- and oil-repellent agent comprising a telechelic polymer. The water- and oil-repellent agent comprises the following components by mass percentage: 20-35% of fluorine-containing polymer, 2-8% of surfactant, auxiliary Agent 2-10% and water. The water and oil repellent provided by the invention has good water and oil repellent effect. The waterproof and oil-repellent agent provided by the invention adopts special raw materials, and has better waterproof and oil-repellent effect, good hand feeling and better washing resistance compared with the prior art.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a waterproof and oil-repellent agent containing a telechelic polymer and a preparation method thereof. Background technique [0002] Water and oil repellents can impart hydrophobic and oleophobic properties to the surface of textiles. The most used on the market is fluorine-containing water and oil repellent. Most of the current waterproof and oil-repellent agents have the disadvantages of poor hand feeling and poor washability, and the efficiency of waterproof and oil-repellent finishing needs to be improved. These disadvantages are rooted in the design defects of the molecular structure of the waterproofing agent. [0003] Kubo Yuanshen (Jubao Yuanshen. Fluorine-containing waterproof and oil-repellent agent (I) - the mechanism of waterproof and oil-repellent properties [J]. Printing and Dyeing, 1995, 21 (12): 37-41) listed conventional waterproof and oil-repellent agents M...
