Embodiment

[0182] Hereinafter, the present invention will be described concretely with reference to examples, comparative examples, and test examples. However, these descriptions do not limit the present invention.

[0183] Hereinafter, unless otherwise specified, parts or % represent parts by weight or % by weight.

[0184] The properties were determined as follows.

[0185] polymer stability

[0186] The aqueous dispersion prepared in the production example was left to stand at room temperature for one week, and the stability was visually evaluated.

[0187]

[0188] Antifouling test

[0189] The antifouling test was carried out with reference to ASTM (American Society for Testing and Materials: American Society for Testing and Materials standard) D6758-00 and JG / T304-2011. Dirt was attached to the sample-coated PET film using water-based whiteboard pens (ZEBRA blue and red) and oil-based markers (Sharpie blue and black). After 10 minutes, wipe with various wiping methods i...

manufacture example 1

[0196] In a 500ml reaction flask, make CF 3 CF 2 -(CF 2 CF 2 ) n -CH 2 CH 2 OCOCH=CH 2 (n=2.0) (C6SFA) 15g, methyl methacrylate 28g, butyl acrylate 22g, hydroxyethyl acrylate 27g, methacrylic acid 3g, methacrylate-3-chloro-2-hydroxypropyl 0.5g, glycerin 0.5 g of methacrylate was dissolved in 150 g of 2-propanol, and after nitrogen substitution in the reaction flask, a solution of 0.4 g of azobisisobutyronitrile and 9 g of water was added, heated to 80° C., and reacted for 20 hours. Then, neutralization was performed, 150 g of pure water was added, and 2-propanol was distilled off at 60 degreeC with stirring, and the aqueous dispersion liquid was obtained. The solid content was adjusted to 40%, and the composition of the polymer was basically the same as that of the loaded monomer.

manufacture example 2

[0198] Add 150 g of pure water, 3 g of alkyl sulfonate, and 3.0 g of polyoxyethylene alkyl ether into a 500 ml reaction flask, and after nitrogen substitution, add 2,2-azobis(2-amidinopropane) dihydrochloride A solution of 0.4g of salt and 9g of water, heated to 80°C, mixed slowly and dropwise added CF 3 CF 2 -(CF 2 CF 2 ) n -CH 2 CH 2 OCOCH=CH 2 (n=2.0) 5 g of (C6SFA), 32 g of methyl methacrylate, 37 g of butyl acrylate, 21 g of hydroxyethyl acrylate, and 3 g of methacrylic acid. After completion of the dropwise addition, it was allowed to react for 20 hours to obtain an aqueous dispersion. The solid content was adjusted to 40%, and the composition of the polymer was basically the same as that of the loaded monomer.

Abstract

The invention relates to a water-based paint composition. The water-based paint composition contains: (1) a fluorine-containing acrylic acid polymer, and (2) an aqueous medium, wherein the fluorine-containing acrylic acid polymer is provided with a repetitive unit originated from a fluorine-containing monomer (a) and a repetitive unit originated from non-fluorinated (meth)acrylate or a (meth)acrylamide monomer (b), the fluorine-containing monomer (a) is a compound shown in a formula CH2=C(.X).C(=O).Y.Z.Rf (I) [in the formula, X is a hydrogen atom, Y is .O. or .NH., Z is a directly bonded or bivalent organic group, and Rf is C1-C20 hydrofluoroalkane]. The water-based paint composition provided by the invention can give excellent water repellent and oil repellent properties, antifouling property and decontaminability, and especially can give excellent antifouling property and decontaminability specific to oily dirt.

Description

technical field [0001] The present invention relates to a water-based coating composition excellent in antifouling property and a coated article whose surface is coated with the composition. Background technique [0002] Conventionally, metal, inorganic, plastic, wood, paper, leather, fiber, and other products are surface-coated for the purpose of protecting the surface, imparting design and functionality, and various coatings have been developed. [0003] Japanese Patent No. 4213257 discloses an antifouling paint and varnish that uses a fluorine-containing copolymer. The fluorine-containing copolymer is composed of 15-85 mole percent of fluoroolefin, 0.1-85 mole percent of perfluoroalkyl acrylate monomer. 20 mol% and 2 to 50 mol% of hemiacetal ester. [0004] Japanese Patent No. 4967190 discloses a water-based coating composition, which contains: 0.1-99% of fluorine-containing monomers with polyfluoroalkyl groups, 0.1-80% of non-fluorine monomers with ketone carbonyl or al...
