Embodiment

[0205] Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these Examples.

[0206] Hereinafter, unless otherwise specified, parts, %, or ratios represent parts by weight, % by weight, or ratio by weight.

[0207] The test procedure is described below.

[0208] Spray water repellency test

[0209] A spray water repellency test was performed in accordance with JIS-L-1092. The spray water repellency test is represented by water repellency No. (number) (as shown in Table 1 described below).

[0210] Use a glass funnel with a volume of at least 250ml and a nozzle capable of spraying 250ml of water in 20-30 seconds. The frame for fixing the test cloth is made of metal with a diameter of 15 cm. Three test cloths having a size of approximately 20 cm×20 cm were prepared, and the test cloths were fixed to the frame so that the test cloths were not wrinkled. Place the center of the spray on the center of the tes...

Abstract

The utility model provides a surface treating agent. By using the surface treating agent, fiber substrate can have good waterproof performance. The surface treating agent includes (1) fluorine-containing polymer provided with (a) a repetitive unit sourced from a fluorine-containing monomer acting as Alpha-chlorin acrylate of perfluoroalkyl and (b) a repetitive unit sourced from a non-fluorine-containing monomer; and (2) cationic surfactant added after the polymerization of fluorine-containing polymer.

Description

technical field [0001] The present invention relates to a fluorine-containing composition (surface treatment agent) containing a fluorine-containing polymer comprising α-chloroacrylate as a constituent monomer, which has high water repellency and excellent stability when inclusions are present in a treatment liquid . Background technique [0002] It is known that a polymer having a perfluoroalkyl group or a perfluoroalkenyl group and a polymerizable compound having an acrylic group or a methacrylic group can be used as a water and oil repellent agent for textiles and the like, especially by using a surfactant to make the polymer An aqueous dispersion obtained by dispersing a polymer in an aqueous medium is widely used industrially. [0003] In addition, it is generally known that excellent durability can be imparted by copolymerizing a chlorine-containing polymerizable compound such as vinyl chloride or vinylidene chloride with the above-mentioned fluorine-containing polyme...
