Abstract

The invention discloses an anti-fingerprint additive for a hard coating and a preparation method thereof. Its components are: perfluoropolyether, fluorine-containing polysiloxane, acrylate monomer and organosilicon ring compound. The preparation method includes: a) adding fluorine-containing polysiloxane and solvent A into a three-necked flask, fully stirring the above solution evenly, and heating to the reaction temperature; b) adding perfluoropolyether and solvent A into the three-necked flask while stirring , to obtain perfluoropolyether and organic fluorosilicon polymer; c) add acrylate monomer, catalyst and solvent A to the three-necked flask under stirring, react for 4-20h, then continue to drop organosilicon ring compound, react for 4-20 hours 10h; d) Cool to room temperature after the reaction, and dilute to 20% solid content with solvent B. The anti-fouling additive of the present invention exists stably at room temperature and has good compatibility with coatings. After UV curing and film formation, it can provide excellent water and oil repellency, anti-fouling, anti-fingerprint, smoothness, Heat resistance and friction resistance properties.

Description

technical field [0001] The invention relates to the technical field of special polymer materials in chemical synthesis, in particular to a hard coating anti-fingerprint additive and a preparation method thereof. Background technique [0002] UV curing refers to a method in which a photoinitiator triggers the rapid polymerization of monomers under the irradiation of ultraviolet light. Compared with thermal curing, UV curing has the advantages of less environmental pollution, high coating film quality, and low energy consumption, so it is widely used in light-curing coatings, adhesives and ink printing, microelectronics and other fields. UV resin has excellent properties such as hardness and light transmittance, and has been widely used in smart phones, tablet computers, and optical displays. Fatty substances such as sweat. [0003] In order to solve the above problems, patent document 1 (CN101146840A) mainly utilizes monofunctional perfluoropolyether alcohols, polyacrylate ...
