Embodiment

[0449] Although the composition of this invention is demonstrated more concretely by the following Example, this invention is not limited to these Examples.

Synthetic example

[0451] ·Synthesis of fluoropolymers

[0452] Fluoropolymer (A) was prepared according to the following procedure.

[0453]

[0454] [where, PFPE represents CF3 CF 2 CF 2 O(CF 2 CF 2 CF 2 O) n CF 2 CF 2 - base, m is an integer of 3-40. ]

Synthetic example 1

[0455] Synthesis Example 1 (Step a): Synthesis of 2-[3-poly(perfluoropropoxy)-2,2,3,3-tetrafluoropropoxy]ethoxyvinyl ether

[0456]

[0457] Put the following structural formula in a 1L eggplant-shaped bottle: PFPE-CH 2 Alcohol containing perfluoropolyether group represented by OH (Demnum SA (number average molecular weight 4000), Daikin Industries Co., Ltd.) 60g (15mmol), tetrabutylammonium hydrogensulfate 3.5g (103mmol), 40% sodium hydroxide aqueous solution 120mL and 250 mL of m-hexafluoroxylene, and stirred at room temperature for 30 minutes under a nitrogen atmosphere. 120 mL of 2-chloroethyl vinyl ether was added to the above mixture, a Dairy cooler was attached to the eggplant flask, and the mixture was stirred at 70° C. for 48 hours under a nitrogen atmosphere. After cooling, the solvent in the reaction solution was distilled off with an evaporator until almost completely dry. The remaining reactants were dissolved in a fluorine-based inert liquid (Fluorinert FC-7...

Abstract

Provided is a surface treatment composition which is capable of forming a surface treatment layer that has excellent wear durability and excellent surface lubricity, while having water repellency, oil repellency and antifouling properties. This surface treatment composition contains (A) at least one fluorine-containing polymer that has a curable moiety and (B) at least one silicon-containing polymer that has a curable moiety.

Description

technical field [0001] The present invention relates to a surface treatment composition. Specifically, it relates to a surface treatment composition containing a fluoropolymer and a silicon-containing polymer. Background technique [0002] Some fluorine-containing compounds are known to provide excellent water repellency, oil repellency, stain resistance, etc. if used in the surface treatment of substrates. The layers obtained from the surface treatment compositions containing fluorine-containing compounds are applied as so-called functional films to various substrates such as glass, plastics, fibers, building materials and the like. [0003] At present, especially in the application of optical parts, substrates made of inorganic glass are used. In order to prevent stains such as fingerprints, a layer using a fluorine-containing compound is formed on the substrate as an antifouling coating. . As such a fluorine-containing compound, a surface treatment composition containi...
