Problems solved by technology

However, heat treatment at high temperature requires high energy, so it is problematic in terms of the international energy-saving trend
[0004] In addition, monomers having a fluoroalkyl group are expensive, so they are not economically satisfactory monomers, and monomers having a fluoroalkyl group are difficult to decompose, so there are problems even from an environmental point of view.

Embodiment 1

[0169] 60 g of stearyl acrylate, LATEMUL PD-420 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether, HLB=12.6) 2 g, LATEMUL PD-430 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether) were added to a 500 mL flask. Ether, HLB=14.4) 2g, octadecyldimethylamine hydrochloride 3g, tripropylene glycol 20g, and water 162.75g were mixed and stirred at 45°C to obtain a liquid mixture. The mixture is irradiated with ultrasonic waves to emulsify and disperse all the monomers. Next, 0.25 g of azobis(isobutylamidine) dihydrochloride was added to the mixed liquid, and it was radically polymerized at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorine-based compound with a polymer concentration of 26% by mass. polymer dispersion.

[0171] 55 g of stearyl acrylate, LATEMUL PD-420 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether, HLB=12.6) 2 g, LATEMUL PD-430 (manufactured by Kao Corporation, polyoxyalkylene alkenyl ether) were added to a 500 mL flask. Ether, HLB=14.4) 2g, 2-hydroxyethyl acrylate 5g, octadecyldimethylamine hydrochloride 3g, dodecyl mercaptan 0.15g, tripropylene glycol 20g and water 162.6g, and at 45 ℃ Mixing and stirring are performed to obtain a liquid mixture. The mixture is irradiated with ultrasonic waves to emulsify and disperse all the monomers. Next, 0.25 g of azobis(isobutylamidine) dihydrochloride was added to the mixed liquid, and it was radically polymerized at 60° C. for 6 hours under a nitrogen atmosphere to obtain a non-fluorine-based compound with a polymer concentration of 26% by mass. polymer dispersion.

Abstract

The present invention is a water repellent composition comprising a non-fluorine-based polymer containing a structural unit derived from a (meth)acrylate monomer (A) and a reactive emulsifier (B) The (meth)acrylate monomer (A) has a monovalent hydrocarbon group with a carbon number of 12 or more that may also have a substituent, and the reactive emulsifier (B) is selected from At least one of the compounds (B1) to (B3) containing overlapping unsaturated groups.

Description

【Technical field】 [0001] The present invention relates to a water-repellent composition, a water-repellent fiber product and a manufacturing method of the water-repellent fiber product. 【Background technique】 [0002] A fluorine-based water-repellent agent having a fluorine-containing group is conventionally known, and a fiber product in which water-repellency is imparted to the surface is known by treating the fluorine-based water-repellent agent on a fiber product or the like. Such a fluorine-based water repellent is generally produced by polymerizing or copolymerizing a monomer having a fluoroalkyl group. [0003] Although fiber products treated with fluorine-based water-repellent agents exhibit excellent water-repellent properties, in order to express water-repellent properties, the orientation of the fluoroalkyl group must be adjusted. temperature for heat treatment. However, heat treatment at high temperature requires high energy, so it is problematic in terms of the...
