Embodiment 1

[0210] As a solvent, 10 parts by mass of MORESCO WHITE P-40 (low-viscosity hydrocarbon, manufactured by MORESCO Co., Ltd., trade name) and DOW CORNING TORAY SH 200 FLUID 100cs (low-viscosity methyl polysiloxane, manufactured by Dow Corning Toray Co., Ltd. , trade name) 10 parts by mass of MQ-1600 (trimethylsilyl-containing polysiloxane, manufactured by Dow Corning Toray Co., Ltd., trade name) as a silicone resin was added, and mixed until organic The silicone was dissolved to obtain a mixture. Next, after confirming that the mixture was uniform, 0.14 parts by mass of laurylamine was added as the compound (1) to the mixture, and the mixture was heated to dissolve laurylamine. The heated mixture was cooled to room temperature. Then, in the cooled mixture, 0.75 mass of SOFTANOL50 (5 moles of ethylene oxide adduct of branched chain alcohol with 12 to 14 carbon atoms, manufactured by Nippon Catalyst Co., Ltd., trade name) as a nonionic surfactant was mixed. and SOFTANOL 90 (a 9-m...

[0214] 30 g of stearyl acrylate, 10 g of lauryl acrylate, 20 g of vinyl chloride, 30 moles of tristyrenated phenol, 5 g of ethylene oxide adduct, and ARCARD (Arcard) T-28 (manufactured by Lion Corporation) were added to a 500 mL pressure-resistant flask. , trade name, stearyl trimethylammonium chloride) 3g, tripropylene glycol 25g and water 206.7g, mixed and stirred at 45°C to prepare a mixed solution. Ultrasonic waves were irradiated to this mixed solution to emulsify and disperse all the monomers. Next, 0.3 g of azobis(isobutylamidine) dihydrochloride was added to the mixed solution, and it was subjected to radical polymerization at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorinated acrylic polymer containing 20% ​​by mass. non-fluorinated acrylic polymer dispersion. Next, 50 parts by mass of the obtained fluorine-free acrylic polymer dispersion containing 20% ​​by mass of the fluorine-free acrylic polymer and 50 parts by mass of the dispersion obtai...

Abstract

This water repellent agent composition contains a compound represented by general formula (1) and a silicone resin. [In formula (1), R31 represents a monovalent hydrocarbon group having 4-30 carbon atoms; R32 represents hydrogen, a monovalent hydrocarbon group having 1-30 carbon atoms, or an organic group represented by -R36-N(R37)-R38 (where, R36 represents a divalent hydrocarbon group having 1-30 carbon atoms, and R37 and R38 each independently represent hydrogen or a monovalent hydrocarbon group having 1-30 carbon atoms); R33 represents a divalent hydrocarbon having 1-30 carbon atoms; R34 and R35 each independently represent hydrogen or a monovalent hydrocarbon group having 1-30 carbon atoms; a represents an integer of 0-2; and when a is 2, a plurality of R32's and R33's may be the same as or different from each other.

Description

technical field [0001] The invention relates to a water-repellent composition and a method for manufacturing water-repellent fiber products. Background technique [0002] Conventionally, a fluorine-based water-repellent agent having a fluorine group is known, and a fiber product in which water repellency is imparted to the surface is known by treating a fiber product or the like with the fluorine-based water-repellent agent. Such a fluorine-based water repellent agent is generally produced by polymerizing or copolymerizing a monomer having a fluoroalkyl group. A fiber product treated with a fluorine-based water repellent exhibits excellent water repellency, but the monomer having a fluoroalkyl group is difficult to decompose, so there is a problem in terms of the environment. [0003] Therefore, in recent years, studies on non-fluorine-based water repellents that do not contain fluorine have been advanced. For example, Patent Document 1 below proposes a water repellent age...
