Embodiment 1

[0113] Add 150 g of C to a 1 L autoclave n f 2n+1 CH 2 CH 2 OCOCH=CH 2 (mixture of compounds with n=6, 8, 10, 12, 14 (n average is 8)) (FA) (fluorine-containing monomer), 75 g of octadecyl acrylate, 3 g of N-methylol propylene Amide, 300 g of pure water, 80 g of tripropylene glycol, 25 g of polyoxyethylene lauryl ether, and 10 g of epoxidized soybean oil were dispersed under ultrasonic emulsification at 40° C. for 30 minutes while stirring. After emulsification, 1 g of n-dodecyl mercaptan was added, and then 40 g of vinyl chloride (chlorine-containing polymerizable compound) was press-filled. 0.8 g of azobisisobutylamidine-2 hydrochloride was added and reacted at 60° C. for 5 hours to obtain an aqueous emulsion of a polymer. The composition of the polymer is such that the reaction rate of vinyl chloride is about 80%, and the reaction rate of other monomers is about 100%. To this aqueous emulsion, 0.7 g of sodium bicarbonate was added to obtain an aqueous dispersion of a ...

Embodiment 2～5

[0117] The same operation as Example 1 was repeated except having used the same weight of the compound shown in Table 1 as a chlorine-containing polymerizable compound and an epoxy compound. In Example 4, the same weight (105 g) of octadecyl α-chloroacrylate was used instead of vinyl chloride and stearyl acrylate.

[0118] In addition, the amount of sodium bicarbonate added when changing the pH setting is as follows.

Abstract

Disclosed is an aqueous liquid dispersion of a water and oil repellent agent which contains (I) a copolymer between a polymerizable compound having a perfluoroalkyl group or perfluoroalkenyl group, and an acrylic acid group, methacrylic acid group or alpha-substituted acrylic acid group, a chlorine-containing polymerizable compound, and another optionally present polymerizable compound which is copolymerizable with the foregoing compounds, and (II) a hydrochloric acid trapping compound. Such an aqueous liquid dispersion of a water and oil repellent agent is excellent in shelf life stability, and is capable of providing a base material with excellent water and oil repellency.

Description

technical field [0001] The present invention relates to an aqueous dispersion of a water- and oil-repellent agent, and more specifically, to an aqueous dispersion of a water- and oil-repellent agent containing a chlorine-capturing compound. Background technique [0002] It is known that a polymer of a polymerizable compound having a perfluoroalkyl or perfluoroalkenyl group and an acrylic or methacrylic acid group can be used as a water and oil repellent agent for fiber fabrics, etc., especially by using a surfactant to polymerize Aqueous dispersions obtained by dispersing substances in aqueous media are widely used in industry. [0003] It is also known that excellent durability can be obtained by copolymerizing a chlorine-containing polymerizable compound such as vinyl chloride, vinylidene chloride, or α-chloroacrylate on the above-mentioned fluorine-containing polymerizable compound. [0004] However, if these copolymers are stored for a long period of time, not only the ...
