Abstract

The invention discloses a hard coating anti-fingerprint additive and a preparation method thereof. The hard coating anti-fingerprint additive contains the following components: perfluoropolyether, fluorine-containing polysiloxane, an acrylate monomer and an organic silicon cyclic compound. The preparation method comprises the following steps: a) adding the fluorine-containing polysiloxane and a solvent A into a three-mouth flask, fully stirring the solution to be uniform, and heating to a reaction temperature; b) adding the perfluoropolyether and the solvent A into the three-mouth flask while stirring so as to obtain a perfluoropolyether and organic fluorosilicone polymer; c) adding the acrylate monomer, a catalyst and the solvent A into the three-mouth flask while stirring, reacting for 4-20 hours, continuing to drip the organic silicon cyclic compound, and reacting for 4-10 hours; and d) cooling to room temperature after the reaction is ended, diluting to the solid content of 20% by using a solvent B. The antifouling additive disclosed by the invention stably exists at the room temperature, has excellent compatibility with coatings, and can provide excellent water resistance, oil resistance, fouling resistance, fingerprint resistance, smoothness, heat resistance and friction resistance for the hard coating after beingsubjected to UV (Ultraviolet)-curable film forming.

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 ...
