Embodiment

[0228] Hereinafter, the present invention will be specifically described with reference to Examples and Comparative Examples. However, these descriptions do not limit the present invention.

[0229] Hereinafter, unless otherwise specified, parts, %, or ratios represent parts by weight, % by weight, or ratio by weight.

[0230] The procedure of the test is described below.

[0231] Bundesmann water repellency test

[0232] According to the method described in JIS L1092 (C) (Bundesmann test), the water repellency was evaluated by raining under the conditions of 80 cc / min of rainfall, 20° C. of rainwater temperature, and 5 minutes or 10 minutes of raining time. The water repellency is represented by 6 grades (0, 50, 70, 80, 90 and 100) from 0 to 100. A higher score indicates better water repellency. Grades marked with + (-) indicate that they are slightly better (worse) in quality.

manufacture example 1

[0234] In a 500mL autoclave, add stearyl acrylate=45g, isobornyl methacrylate=5g, pure water=145g, tripropylene glycol=15g, sorbitan monooleate=1.5g, polyoxygen Ethylene (EO: 18) secondary alkyl (C12-14) ether = 2 g, di-octadecyl dimethyl ammonium chloride = 1.5 g, ultrasonic emulsification and dispersion at 60° C. for 15 minutes while stirring. After substituting nitrogen in the autoclave, 2,2-azobis(2-amidinopropane) 2 hydrochloride=0.5 g was added, and it was made to react at 60 degreeC for 3 hours, and the aqueous dispersion liquid of the polymer was obtained. Further, the solid content concentration was adjusted to 30% with pure water. The monomer composition of the resulting polymer is basically the same as that of the added monomer.

manufacture example 2

[0236] Add stearyl acrylate=40g, isobornyl methacrylate=10g, pure water=145g, tripropylene glycol=15g, acetylene glycol polyoxyethylene adduct=1g, Polyoxyethylene (EO: 18) isotridecyl ether = 2 g, dioctadecyl dimethyl ammonium chloride = 2 g, and was dispersed by ultrasonic emulsification at 60° C. for 15 minutes while stirring. After substituting nitrogen in the autoclave, 2,2-azobis(2-amidinopropane) 2 hydrochloride=0.5 g was added, and it was made to react at 60 degreeC for 3 hours, and the aqueous dispersion liquid of the polymer was obtained. Further, the solid content concentration was adjusted to 30% with pure water. The monomer composition of the resulting polymer is basically the same as that of the added monomer.

Abstract

The present invention provides a surface treatment agent that does not use a fluorine-containing monomer, especially a fluorinated alkyl-containing monomer. The surface treatment agent is an aqueous emulsion, containing: (1) non-fluoropolymer, which has a formula derived from (i): CH2=CA11-C(=O)-O-A12 [wherein, A11 is a hydrogen atom or a group, A12 is a straight-chain or branched aliphatic hydrocarbon group with 18 to 30 carbon atoms] a repeating unit of a long-chain (meth)acrylate monomer represented by (ii) a (meth)acrylate monomer having a cyclic hydrocarbon group base) repeating units of an acrylate monomer; (2) a surfactant comprising one or both of a nonionic surfactant and a cationic surfactant; and (3) an aqueous liquid medium.

Description

technical field [0001] The present invention relates to surface treatment agents, especially water and oil repellents and antifouling agents. 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 "PRELIMINARY RISK ASSESSMENT OF THEDEVELOPMENTAL TOXICITY ASSOCIATED WITH EXPOSURE TO PERFLUOROOCTANOIC ACID ANDITS SALTS" (http: / / www.epa.gov / opptintr / pfoa / pfoara.pdf)], etc., as long-chain fluorine PFOA (perfluorooctanoic acid), a kind of substituted alkyl compound, has gradually become clear about the environmental load concerns. On April 14, 2003, the EPA (US Environmental Protection Agency) issued an intensified scientific investigation on PFOA. [0004] On the other hand, Federal Register (FR Vol.68, No.73 / Apri...
