[0235] Hereinafter, the present invention will be described in detail by way of examples, but the present invention is not limited to these examples.
[0236] Examples 1 to 13 are production examples, Examples 15, 22 to 26, 28 to 30, and 32 to 37 are examples, and Examples 14, 16 to 21, 27, and 31 are comparative examples.

[0238] The molecular weight of the copolymer recovered by the recovery method described below was measured.
[0239] (recycling method)
[0240]6 g of emulsions were added dropwise to 60 g of 2-propanol (hereinafter referred to as IPA), and stirred to deposit a solid. The resulting solid was isolated after centrifugation at 3000 rpm for 5 minutes. 12 g of IPA was added again, and it stirred well. After centrifugation at 3000 rpm for 5 minutes, the resulting solid was separated from the supernatant, and vacuum-dried overnight at 35° C. to obtain a copolymer.

[0307] Add 218g of FMA, 3g of HEMA, 109g of PEO-13, 96g of AM3130, 82g of DPG, 239g of water, and 0.3g of StSH into a glass beaker, heat at 60°C for 30 minutes, and then use homogeneous mixing machine (BIO Mixer, manufactured by Nippon Seiki Seisakusho Co., Ltd.), to obtain a mixed solution.
[0308] The obtained mixed solution was treated at 40 MPa with a high-pressure emulsifier (manufactured by APV Ranier, Minilab) while maintaining the temperature at 60° C. to prepare an emulsion. The obtained emulsion liquid was poured into the reaction container made of stainless steel, and it cooled to 40 degreeC or less. After adding 1.3 g of V-50 and replacing the gas phase with nitrogen, 49 g of VDC was introduced, and a polymerization reaction was performed at 60° C. for 15 hours while stirring to obtain an emulsion of a copolymer (A-1). The solid content was 36.1% by mass. Table 2 shows the input amount of each raw material. Table 3 shows the ratio of each monomer unit, the adde...

Abstract
The present invention can obtain a porous substrate having a moisture-permeable, waterproof film and a water-repellant, oil-repellant treated surface that has favorable water-repellant, oil-repellant properties and washing durability, has suppressed permeation of a coating liquid for forming the moisture-permeable, waterproof film, and has suppressed delamination of the moisture-permeable, waterproof film. This water-repellant, oil-repellant composition contains: a copolymer (A) having 60-95 mass% of a unit that is on the basis of a monomer having an RF group having no greater than 6 carbon atoms, and 5-40 mass% of a unit that is on the basis of vinylidene chloride; a copolymer (B) having 50-95 mass% of a unit that is on the basis of a halogenated olefin and 5-50 mass% of a unit that is on the basis of a monomer having a cross-linkable functional group; and a medium (C). The proportion of copolymer (A) is 70-90 mass%, and the proportion of copolymer (B) is 10-30 mass%.
Description
technical field [0001] The present invention relates to a water- and oil-repellent composition and an article whose surface is treated with the water- and oil-repellency composition. Background technique [0002] As a method of imparting water and oil repellency to the surface of a base material such as cloth, it is known to use a polyfluoroalkyl group based on a carbon number of 8 or more (hereinafter, the polyfluoroalkyl group is referred to as R f A method of dispersing a copolymer of monomer units of the base) in an aqueous medium to obtain an emulsion, and treating a substrate with a water and oil repellent composition composed of the emulsion. [0003] However, recently EPA (U.S. National Environmental Protection Agency) pointed out that perfluoroalkyl groups having a carbon number of 7 or more (hereinafter, the perfluoroalkyl group is referred to as R F base) compounds are decomposed in the environment and in vivo, and the decomposition products may accumulate, that ...
