Abstract

The invention discloses a surface treatment composition containing fluorinated polyether siloxane. The composition comprises: (1) 70-99.99 parts by mass of fluorinated polyether siloxane which is represented by general formulae (A) and (B): (R<f>)[alpha]-M-(S)[beta] (A), (S)[beta]-M-(R<f>)-M-(S)[beta] (B), R<f> is a monovalent or divalent polyfluoropolyether group, M is a covalent bond or at leastdivalent organic linking group, S is a silyl group containing a hydroxyl group or a hydrolysable group, alpha and beta are both an integer of 1-10, and the sum of alpha and beta is smaller than or equal to 10, and the fluorinated polyether siloxane represented by the formula (B) in the fluorinated polyether siloxane at most accounts for 35% of the total mass of the fluorinated polyether siloxane;and (2) 0.01-30 parts by mass of a silane compound simultaneously containing an amino group and a hydroxyl group or a hydrolysable group. An antifouling coating prepared from the composition is excellent in antifouling property and wear resistance, can be cured at room temperature, and is good in smoothness and excellent in hand feeling.

Description

technical field [0001] The invention relates to a surface treatment composition, in particular to a surface treatment composition containing fluorinated polyether siloxane, which belongs to the technical category of surface treatment. Background technique [0002] The transparent optical devices of touch-type electronic display devices (such as mobile phone glass screens, etc.) are often in contact with fingers, and are easily polluted by fingerprints, sweat, oil, etc., and once the dirt is formed, it is difficult to remove without using solvents. There is a danger of damaging the display device; on the other hand, dirt also affects the visual perception of the display device. In order to prevent contamination of display devices by dirt and possible damage to devices during the removal of dirt, it is of great significance to develop surface coatings with antifouling and easy decontamination functions. [0003] In order to achieve the above objectives, researchers have devel...
