Problems solved by technology

For the above reasons, there is a problem that in a (meth)acrylate polymer having a fluoroalkyl group having a side chain whose carbon number is as short as 7 (especially 6 or less), since the crystallinity of the side chain is low, Therefore, the practical performance cannot be satisfied by using it as it is.
In these gazettes, there is no research on strong water repellency

Embodiment

[0143] Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these Examples.

[0144] Hereinafter, unless otherwise specified, a part or % or a ratio means a weight part or a weight % or a weight ratio.

[0145] The procedure of the test is described below.

[0146] Spray water repellency test

[0147] According to JIS-L-1092, the spray water repellency test was carried out. The spray water repellency test is represented by water repellency No. (as shown in Table 1 described below).

[0148] Use a glass funnel with a volume of at least 250 ml and a spray nozzle capable of spraying 250 ml of water in 20 to 30 seconds. The test piece frame is a metal frame with a diameter of 15 cm. Three test piece sheets having a size of about 20 cm×20 cm were prepared, and the sheets were fixed on the test piece fixing frame so that there were no wrinkles in the sheets. The center of the spray was placed at the center of...

[0160] Add CF to 500ml reaction flask 3 CF 2 -(CF 2 CF 2 ) n -CH 2 CH 2 OCOC(Cl)=CH 2 (n=2.0) 14.9g, stearyl acrylate 13.47g, isobornyl methacrylate 33.71g, pure water 110g, dipropylene glycol monomethyl ether 18.62g, dioctadecyldimethylammonium chloride 3.08g, octadecyltrimethylammonium chloride 0.87g, polyoxyethylene lauryl ether (EO: 20. EO represents the number of ethylene oxide units) 2.1g, polyoxyethylene isotridecyl ether (EO : 3) 0.65 g was emulsified and dispersed at 60° C. for 15 minutes with stirring. After nitrogen substitution in the reaction flask, 0.62 g of dodecylmercaptan, 0.31 g of 2,2-azobis(2-amidinopropane) dihydrochloride (hereinafter referred to as V-50) and 9 g of water were added The solution was reacted at 60°C for 5 hours to obtain an aqueous dispersion of the polymer. The composition of the polymer is nearly identical to that of the feed monomer.

Abstract

The present invention discloses a fluorine-containing composition comprising a fluorine-containing polymer having repeating units derived from (A) a fluorine-containing acrylate as an alpha-chloroacrylate having a fluoroalkyl group Monomers, (B) a monomer having a linear or branched hydrocarbon group without a fluoroalkyl group, and (C) a monomer having a cyclic hydrocarbon group without a fluoroalkyl group.

Description

technical field [0001] The present invention relates to a fluorine-containing composition (fluorine-containing treatment agent composition), in particular to a surface treatment agent composition such as a water and oil repellent composition. The composition of the present invention can be used to impart excellent water repellency, oil repellency, and stain resistance to fiber products (such as carpets), paper, nonwoven fabrics, stone materials, electrostatic filters, dust covers, and parts of fuel cells. Background technique [0002] Currently, various fluorine-containing compounds have been proposed. Fluorine-containing compounds have the advantage of being excellent in properties such as heat resistance, oxidation resistance, and weather resistance. Fluorine-containing compounds are used as water and oil repellents and antifouling agents, for example, by taking advantage of the low free energy of fluorine-containing compounds, that is, the property that they are difficul...
