Abstract

The invention discloses a preparation method of a high-performance fingerprint-resistant agent. The preparation method includes the following steps that hydroxyl-terminated perfluorinated polyether and allyl bromide react to obtain allyl-terminated perfluorinated polyether; allyl-terminated perfluorinated polyether and hydrogen-containing silicone oil are subjected to a layer adding reaction through silicone hydrogen, and perfluorinated polyether-hydrogen-containing silicone oil (unreacted hydrogen still exists in silicone oil) is obtained; the obtained product and allyl siloxane continue to be subjected to a silicone hydrogen water adding reaction to obtain a needed target product pectinate perfluorinated polyether-siloxane; then pectinate perfluorinated polyether-siloxane is prepared into the fingerprint-resistant agent. The prepared fingerprint-resistant agent has the advantages of being good in hydrophobic and oleophobic performance, excellent in anti-fouling property and good in fingerprint easy-to-move property, a fingerprint-resistant coating and a glass base material are high in bonding force, the product is good in abrasion resistance, and compared with the prior art, the durability and abrasion resistance of the fingerprint-resistant agent are greatly improved.

Description

technical field

[0001] The invention relates to the fields of touch screens, optical glass, architectural glass, etc., and in particular to a comb-shaped perfluoropolyether-siloxane obtained by reacting hydroxyl-terminated perfluoropolyether, hydrogen-containing silicone oil and allyl siloxane Alkanes can be formulated into high-performance anti-fingerprint agents. Background technique

[0002] In recent years, touch panelization of screens, represented by mobile phone displays, is accelerating. However, the exposed state of the touch panel makes it easy to be polluted by fingerprints, skin oil, sweat, cosmetics, etc. during use, which affects the appearance and use. Therefore, in order to improve the appearance and recognition, there are more and more requirements for the technology of making fingerprints not easy to adhere to the display surface or the technology of easy to remove dirt. The surface is not easy to cause damage, and it must have good wear resistance. Ther...
