Problems solved by technology

[0003] However, the water and oil repellent compositions of Patent Document 1 and Patent Document 2 are insufficient in water and oil repellency, especially in durability of water and oil repellency.
[0004] In addition, in the existing processing baths of water- and oil-repellent agents prepared by diluting and blending general aqueous dispersions, the following problems often occur: the dispersions are broken due to the mechanical impact received when the blanks are placed into them. Destruction, coagulation and precipitation of emulsified particles, polymer adhesion on the dial roller, resulting in substrate contamination, roller contamination, etc.

Embodiment 1

[0185] Add monomer A:C to 1L autoclave 6 f 13 CH 2 CH 2 OCOC(Cl)=CH 2 (C6SFCLA) 110g, monomer B: lauryl methacrylate (LMA) 48g, monomer D: cyclohexyl methacrylate (CHMA) 42g, pure water 446g, tripropylene glycol 76g, polyoxyethylene dodecyl 10.2 g of alkyl ether, 2.47 g of polyoxyethylene octadecyl ether, and 7.6 g of polyoxyethylene isotridecyl ether were emulsified and dispersed using a high-pressure homogenizer after heating at 60°C. After emulsification, 2.5 g of dodecyl mercaptan and 62 g of monomer C: vinyl chloride (VCl) were charged under pressure. Furthermore, 1.6 g of 2,2- azobis(2-amidinopropane) dihydrochloride was added, and it was made to react at 70 degreeC for 3 hours, and the aqueous dispersion liquid of a polymer was obtained. The water repellency (water and oil repellency) and viscosity of the aqueous dispersion liquid whose solid content concentration was adjusted to 30 weight% with pure water were evaluated. The results are shown in Table 2.

Embodiment 2

[0187]Use lauryl acrylate (LA) as monomer B, omit monomer C: vinyl chloride (VCl), add monomer F: glycerol monomethacrylate (GLM), in addition, with embodiment 1 In the same manner, an aqueous dispersion of the polymer was obtained (refer to Table 2 for the input amount of each component). The water repellency and viscosity of the aqueous dispersion whose solid content concentration was adjusted to 30% by weight with pure water were evaluated. The results are shown in Table 2.

Embodiment 3

[0189] Use octyl acrylate (OA) as monomer B, add monomer E: diacetone acrylamide (DAAM) and monomer F: glycerol monomethacrylate (GLM), in addition, operate in the same way as in Example 1, An aqueous dispersion of the polymer was obtained (see Table 2 for the input amount of each component). The water repellency and viscosity of the aqueous dispersion whose solid content concentration was adjusted to 30% by weight with pure water were evaluated. The results are shown in Table 2.

Abstract

Disclosed is a fluorine-containing polymer comprising: (a) a repeat unit in which the alpha-position is an acrylate ester monomer substituted with a monovalent organic group or a halogen atom and which is derived from a fluorine-containing monomer having a fluoroalkyl group; (b) a repeat unit which is an alkyl acrylate having a C6-13 alkyl group and is derived from a non-fluorine monomer; and (c) a repeat unit derived from a non-fluorine (meth)acrylate monomer having a cyclic hydrocarbon group. A surface treatment agent which imparts a base material with excellent water repellency, oil repellency, anti-soiling properties, and soil release properties can be obtained.

Description

technical field [0001] The present invention relates to a fluoropolymer and a treatment agent containing the fluoropolymer. The treatment agent of the present invention is excellent in water and oil repellency, and particularly excellent in durability of water and oil repellency. Background technique [0002] Conventionally, for example, International Publication No. 2002 / 083809 (Patent Document 1), International Publication No. 2009 / 008512 (Patent Document 2) and International Publication No. 2004 / 096939 (Patent Document 3) have proposed the use of fluoropolymers various surface treatment agents. Patent Document 1 and Patent Document 2 disclose the composition of a water and oil repellent agent containing a fluoropolymer containing a (meth)acrylate monomer having an alkyl group having 15 or more carbon atoms, such as stearyl acrylate. thing. [0003] However, the water and oil repellent compositions of Patent Document 1 and Patent Document 2 are not sufficient in water a...
