[0624]

[0625] Represented compound 25g (5.9×10 -3 mol), diethylene glycol 2-bromoethyl methyl ether 3g (1.3×10 -2 mol), tetrabutylammonium iodide 0.05g (1.3×10 -4 mol) mixed. Next, after adding potassium hydroxide 1.8g (3.3×10 -2 mol), heated at 60°C for 6 hours. Then, 3 g of diethylene glycol 2-bromoethyl methyl ether (1.3×10 -2 mol), potassium hydroxide 1.8g (3.3×10 -2 mol), heated at 60°C for 14 hours. Furthermore, after adding diethylene glycol 2-bromoethyl methyl ether 3g (1.3×10 -2 mol), potassium hydroxide 1.8g (3.3×10 -2 mol), heated at 60°C for 4 hours. After heating, it was cooled to room temperature, and aqueous hydrochloric acid solution was added dropwise. After recovering the fluorine compound layer as the lower layer by a liquid separation operation, it was washed with acetone. The lower layer after cleaning is recovered again, i.e. the fluorine compound lay...

Abstract

The fluorine-containing coating agent composition contains: (A) an organic silicon compound containing a hydrolyzable group or a hydroxy group modified by a fluorooxyalkylene group-containing polymerresidue, and / or a partial (hydrolyzed) condensate thereof; and (B) an organic silicon compound containing a polyether group and a hydrolyzable group or a hydroxy group modified by a fluorooxyalkylenegroup-containing polymer residue, and / or a partial (hydrolyzed) condensate thereof, wherein the mixture mass ratio of component (A) and component (B) is 15:85-85:15. When the composition is applied asa surface treatment agent, the surface treatment agent containing the fluorine-containing coating agent composition can form a cured coating film which has excellent water repellency and oil repellency, and which has both excellent steel wool abrasion resistance and eraser rubber abrasion resistance.

Description

technical field [0001] The present invention relates to a fluorine-containing coating composition, in particular, to a hydroxyl or hydrolyzable group-containing organosilicon compound modified with a polymer residue containing a fluorinated oxyalkylene group and / or a part thereof (hydrolyzed) condensates and organosilicon compounds containing hydroxyl or hydrolyzable groups and polyether groups modified with polymer residues containing fluorooxyalkylene groups and / or partial (hydrolyzed) condensates thereof to specific A fluorine-containing coating agent composition that forms a film with excellent water and oil repellency and abrasion resistance, a surface treatment agent containing the composition, and an article surface-treated with the surface treatment agent. Background technique [0002] In recent years, touch panelization of screens has been accelerated, including displays for mobile phones. However, the screen of the touch panel is bare, and there are many chances o...
