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 an efficient water-proofing and oil-proofing agent containing a telechelic polymer. The water-proofing and oil-proofing agent comprises the following components in percentage by mass: 20 to 35 percent of fluorine-containing polymer, 2 to 8 percent of surfactant, 2 to 10 percent of an aid and water. The water-proofing and oil-proofing agent provided by the invention has goodwaterproof and oilproof effects. The water-proofing and oil-proofing agent provided by the invention adopts special raw materials, and have better waterproof and oilproof effects, better hand feelingand more excellent 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...
