Problems solved by technology

The vinyl chloride / vinylidene chloride has better water resistance and good water resistance effect in textile application processing fibers, but due to the low boiling point of olefins, it often causes danger when the emulsification reaction temperature of acrylic is increased, and the latter is in the latter stage. When processing textile fibers, it often causes problems such as monomer residues

Synthetic example 1

[0109] Synthesis Example 1: Fluorine-containing monomer with urethane structure (D-V1)

[0110] Place 100 grams of IPDI monomer and 0.03 grams of catalyst ES 100Ag catalyst in a three-neck round bottom bottle equipped with a mechanical stirrer, and add 55.6 grams of HEMA (2-hydroxyethyl methacrylate) into the round bottom bottle by dropwise addition, with full temperature control Below 40°C and react for 3 hours. In the second step, add 163 grams of dodecafluoroheptanol (2,2,3,3,4,4,5,5,6,6,7,7-dodecafluorooctan-1-ol) into the circle dropwise In the bottom bottle, the temperature was controlled below 40°C throughout the whole process and the reaction was carried out for 4 hours. After the reaction is completed, 318.6 grams of transparent and colorless mucus can be obtained.

[0112] Synthesis Example 2: Fluorine-containing monomer with urethane structure (D-V2)

[0113] Place 100 grams of IPDI monomer and 0.03 grams of catalyst ES 100Ag catalyst in a three-neck round bottom bottle equipped with a mechanical stirrer, and add 55.6 grams of 2-hydroxypropyl methacrylate into the round bottom bottle by dropwise, and the temperature control throughout the process is below 40 °C and reacted for 3 hours. In the second step, 156.6 grams of dodecafluoroheptanol (2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptan-1-ol) was added dropwise into the circle In the bottom bottle, the temperature was controlled below 40°C throughout the whole process and the reaction was carried out for 4 hours. After the reaction is completed, 312.2 grams of transparent and colorless mucus can be obtained.

Abstract

The invention relates to a fluorine water-repellent and oil-repellent agent, provides a fluorine-containing copolymer, a hydroxyl-containing cationic surfactant, a polyoxyethylene ester group-containing nonionic surfactant, self-synthetic fluorine-containing polyurethane monomers, and forming a stable water-dispersible fluorine water-repellent and oil-repellent agent via an emulsion polymerization.

Description

technical field [0001] The present invention relates to a surface treatment agent, and more specifically refers to a fluorine water and oil repellent agent. Background technique [0002] Fluorine-containing compounds are often used as surface treatment agents and are widely used in the surface treatment of substrates, such as textiles, wood, metal, concrete, etc. The substrates that can show better results are textiles, which include natural fibers , Synthetic fiber and semi-synthetic fiber, the fluorine-containing compound can make the surface of the fiber hydrophobic, prevent water from adhering and reduce pollution. [0003] At present, to make fiber products have water-repellent and oil-repellent properties, fluoroalkyl acrylates are commonly used, and water-based fluorine-containing water- and oil-repellent agents obtained by emulsification and copolymerization with copolymerizable monomers. [0004] It is known that in order to improve the straight-chain perfluoroalky...
