Problems solved by technology

[0005] In addition, in the existing water-repellent and oil-repellent processing bath prepared by diluting the general aqueous dispersion, due to the mechanical impact received when it enters the treated gray cloth, the dispersion is destroyed, the emulsion particles are coagulated, precipitation, etc. Problems such as greige pollution and roll pollution caused by objects attached to the rollers occurred frequently
Although several methods with excellent stability of inclusions have been proposed (e.g. Japanese Patent Application Laid-Open No. 9-118877, WO2004 / 069924), with the diversity of water and oil repellent processing in recent years, it may not be possible to provide sufficient stability to meet the requirements. sex
Also, regarding the problem of polymer sticking to the roll, the more adhesive the polymer, the more likely it is to cause problems

Embodiment

[0228] Hereinafter, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these Examples.

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

[0230] The test procedure is described below.

[0231] Spray water repellency test

[0232] A spray water repellency test was performed in accordance with JIS-L-1092. The spray water repellency test is represented by water repellency No. (as shown in Table 1 described below).

[0233] 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 test piece frame is a metal frame with a diameter of 15 cm. Three test piece sheets having a size of approximately 20 cm×20 cm were prepared, and the sheets were fixed to the test piece fixing frame so that the sheets were not wrinkled. Place the center of the spray in the center of the sheet. Water...

[0249] Add CF to a 300mL autoclave 3 CF 2 -(CF 2 CF 2 ) n -CH 2 CH 2 OCOC(Cl)=CH 2 (n=2.0) (C6SFClA) 18.63g, stearyl acrylate (StA) 42.84g, isobornyl acrylate (IBMA) 0.62g, pure water 110g, dipropylene glycol monomethyl ether 18.62g, octadecyltri Methyl ammonium chloride 2.57g, polyoxyethylene lauryl ether (EO: 20. EO represents the number of ethylene oxide units) 2.65g, polyoxyethylene isotridecyl ether (EO: 3) 1.21g, under stirring, It was emulsified and dispersed by ultrasonic waves at 60°C for 15 minutes. After nitrogen substitution in the reaction flask, 0.62 g of lauryl mercaptan, 0.31 g of 2,2-azobis(2-amidinopropane) 2 hydrochloride (hereinafter referred to as V-50) and 9 g of water were added. solution, reacted at 60°C for 5 hours to obtain an aqueous dispersion of the polymer. The composition of the polymer is substantially identical to that of the feed monomer.

[0250] Carry out adhesive adhesion test and adhesion test. Table A shows the test results.

Abstract

The invention provides a water-repellent oil-repellent composition imparting excellent water- repellency and oil-repellency to substrates such as fiber products, and preventing the adhesion of the polymer on a roller in processing. The water-repellent oil-repellent composition is a fluorine-containing composition comprising a fluorine-containing polymer, and the fluorine-containing polymer has: (a) repeating units derived from a fluorine-containing monomer having a fluoroalkyl group, (b) repeating units derived from a second monomer, wherein the second monomer is a straight-chain or branched-chain hydrocarbon acrylate monomer having a carbon atom number of 12 to 30, and (c) repeating units derived from a third monomer, wherein the third monomer is an acrylate monomer with homopolymer glass transition temperature (Tg) or the melting point (Tm) of more than 50 DEG C (methyl); and in the fluorine-containing polymer, relative to the total amount of the second monomer (b) and the third monomer (c) being 100 parts by weight, the second monomer (b) is in an amount of 82 to 99.9 parts by weight or 2 to 60 parts by weight, and the third monomer (c ) in an amount of 0.1 to 18 parts by weight or 40 to 98 parts by weight.

Description

technical field [0001] The present invention relates to a fluorine-containing composition and a fluorine-containing polymer. According to the present invention, it is possible to produce fluorine-containing polymers that impart excellent water repellency, oil repellency, and antifouling properties to fiber products (such as carpets), paper, non-woven fabrics, stone materials, electrostatic filters, dust covers, and parts of fuel cells. things. 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, for example, as water and oil repellents and antifouling agents, taking advantage of their low free energy, that is, the property of being difficult to adhere. For example, U.S. Patent No. 5,247,008 describes an aqueous dispersion of a copolymer ...
