Embodiment

[0213] Hereinafter, the present invention will be specifically described with reference to Examples and Comparative Examples. However, these descriptions do not limit the present invention.

[0214] Hereinafter, unless otherwise specified, parts, %, or ratios represent parts by weight, % by weight, or ratio by weight.

[0215] The procedure of the test is described below.

[0216] Spray water repellency test

[0217] According to JIS-L-1092, the spray water repellency test was carried out. The spray water repellency test (shown in Table 1 below) is represented by water repellency No.

[0218] Use a glass funnel with a volume of at least 250ml and a nozzle capable of dispensing 250ml of water in 20-30 seconds. The test piece frame is a metal frame with a diameter of 15 cm. Three test pieces with a size of about 20 cm×20 cm were prepared, and the pieces were fixed to the test piece support frame so that the pieces were not wrinkled. Center the spray so that it is in the ...

manufacture example 1

[0223] Add stearyl acrylate 115.20g, pure water 240g, tripropylene glycol 33.0g, stearic acid dimethylaminopropylamide 6.08g, polyoxyethylene isotridecyl ether ( EO: 18. EO represents the number of oxyethylene units) 5.43g, polyoxyethylene isotridecyl ether (EO: 3) 1.71g, acetic acid 2.4g, under stirring at 60 ℃ with ultrasonic emulsification dispersion 15 minute. After nitrogen substitution in the reaction flask, a solution of 0.24 g of lauryl mercaptan, 0.48 g of 2,2-azobis(2-amidinopropane) 2 hydrochloride, and 9 g of water was added, and the reaction was carried out at 60° C. for 5 hours. An aqueous dispersion of the polymer is obtained. The composition of the polymer is basically the same as that of the added monomers.

Abstract

Provided is a surface treatment agent that does not use a fluorine-containing monomer, and in particular does not use a monomer containing a fluoroalkyl group. Disclosed are (1) a non-fluorinated polymer that comprises a repeating unit that is derived from a long-chain (meth)acrylate ester monomer indicated by formula (a), CH2=CA11-C(=O)-O-A12 (wherein A11 is a hydrogen atom or a methyl group, and A12 is a straight chain or branched aliphatic hydrocarbon group that has 18-30 carbons), (2) a surfactant that contains a surface-active compound that has either or both an amide group and an amino group, and (3) a surface treatment agent that is an aqueous emulsion that contains a liquid medium that contains water.

Description

technical field [0001] The invention relates to an aqueous emulsion surface treatment agent, especially a water and oil repellant and an antifouling agent. Background technique [0002] Fluorine-containing water and oil repellent agents containing fluorine-containing compounds are currently known. The water and oil repellent agent exhibits good water and oil repellency when treating substrates such as fiber products. [0003] According to recent research results [EPA report "PRELIMINARYRISKASSESSMENTOFTHEDEVELOPMENTALTOXICITYASSOCIATEDWITHEXPOSURETOPERFLUOROOCTANOICACIDANDITSSALTS" (http: / / www.epa.gov / opptintr / pfoa / pfoara.pdf)], as a long-chain fluoroalkyl compound, PFOA (perfluorooctanoic acid: perfluorooctanoic acid) Concerns about environmental load gradually became clear. On April 14, 2003, the EPA (US Environmental Protection Agency) issued an intensified scientific investigation on PFOA. [0004] On the other hand, Federal Register (FRVol.68, No.73 / April16, 2003 [FRL...
