Problems solved by technology

When R f When it is reduced to a fluoroalkyl group with 4-6 carbon atoms, the waterproof and oil-proof function of the surface treatment agent becomes worse, and vinyl chloride or vinylidene chloride must be used to improve its effect; however, the use of vinyl chloride or vinylidene chloride The mixture of olefinic monomers and perfluoroalkylethyl methacrylate has effective water resistance and good water resistance when applied to textile processing fibers, but there is a problem of adhesion to the roller

manufacture example 1

[0050] Manufacturing example 1, as shown in Table 3, perfluorooctyl alcohol methacrylate (6FMA) 75g, isobornyl acrylate (IBOA) 15g, glycidyl methacrylate (GMA) 2.5g, diacetone acrylamide (DAAM) 6g, n-dodecyl mercaptan 0.75g, dipropylene glycol methyl ether 43.5g and deionized water 300g were stirred at 50°C for 20 minutes, and homogenized under high pressure at 40MPa. Put the high-pressure homogeneous emulsion into a 1L four-neck glass reaction bottle, add 0.8g of 2,2'-azobisisobutylamidine dihydrochloride, 28g of vinylidene chloride (VDC), and react at 60°C for 6 hours , to obtain an aqueous dispersion of acrylic polymer.

manufacture example 2

[0051] Manufacturing example 2, as shown in Table 3, perfluorooctyl alcohol methacrylate (6FMA) 75g, isobornyl acrylate (IBOA) 24g, glycidyl methacrylate (GMA) 2.5g, diacetone acrylamide (DAAM) 6g, n-dodecyl mercaptan (0.75g), dipropylene glycol methyl ether 43.5g and deionized water 300g were stirred at 50°C for 20 minutes, and homogenized under high pressure at 40MPa. Put the high-pressure homogeneous emulsion into a 1L four-neck glass reaction bottle, add 0.8g of 2,2'-azobisisobutylamidine dihydrochloride, 45g of vinylidene chloride (VDC), and react at 60°C for 6 hours , to obtain an aqueous dispersion of acrylic polymer.

Abstract

The invention discloses a water and oil drawing agent which is at least prepared by polymerizing a fluorine-containing monomer (A), a non-fluorine branched-chain monomer (B), a non-fluorine cross-linked monomer (C) and an olefin monomer (D), therefore, the favorable water and oil drawing effect can be achieved, and the adhesion problem on a roller can be relieved.

Description

technical field [0001] The invention relates to a water and oil repellent agent; in particular, it refers to a water and oil repellent agent belonging to fluorine-containing polymers. 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 For fibers and semi-synthetic fibers, this fluorine-containing chemical can make the surface of the fibers water-repellent and oil-repellent. [0003] Known according to the literature, such as the right formula H 2 C=C(X)C(=O)-Y-Z-R f refers to the perfluoroalkyl ethyl acrylate, when R f When the fluoroalkyl group has 8 carbon atoms, it is suitable for the manufacture of waterproof and oil-proof surface treatment agents. When R f When it is reduced to a fluoroalkyl group with 4-6 carbon ...
