preparation example Construction

[0047] The preparation method of the antifouling film of the present invention is not particularly limited, for example, it can be produced by a coating method comprising the following steps:

[0048] (1) The coating composition prepared by blending components such as polyfluorosiloxane acrylic comb-type graft copolymer and antistatic agent (if necessary, other known additives can be added and diluted with solvent) is formulated into Coating solution;

[0049] (II) coating the coating solution on the surface of the substrate through a wire rod coating rod to form an antifouling layer;

[0050] (III) Sending the coated substrate into a dryer, heating at a suitable temperature for several minutes, evaporating the solvent, and performing thermal curing polymerization.

[0051] The solvent system described in the above step (I) is not particularly limited, for example, it may be benzene, ester or ketone or a mixture thereof. Non-limiting examples of benzene-based solvents includ...

Embodiment 1

[0058] Get 1 part by weight of polyfluorosiloxane acrylic acid-based comb-type graft copolymer [E-4263, Eternal Company] (about 55% of solid content), the main chain of the copolymer is an acrylic polymer, branched The chain part is composed of 2% fluorinated acrylic monomer and 3% siloxane monomer, the molecular weight is 20000~30000, adding 0.3 parts by weight of isocyanate crosslinking agent [Desmodur 3390, Bayer company] (solid content About 75%), then add 3 parts by weight of quaternary ammonium salt antistatic agent [GMB-36M-AS, Marubishi oil Chem.Co., Ltd] (solid content about 20%) to form a coating composition, finally use propylene glycol methyl Dilute with ether, ethyl acetate, toluene and other solvents to obtain a coating with a solid content of about 2.5% and a viscosity of less than 10 cps. After standing for defoaming, apply the prepared coating on a polyethylene terephthalate (PET) film [T100G-38, Mitsubishi Chem.Co.] (thickness 38 μm) through a wire rod coatin...

Embodiment 2

[0061] Use the coating composition and method of embodiment 1 to prepare antifouling film, but change the solid coating amount of antifouling layer to 75mg / m 2 .

Abstract

The invention provides an anti-fouling film containing base material, wherein, at least one side of the base material is provided with a coating compound to serve as an anti-fouling layer, the anti-fouling layer is formed by the coating compound, and the coating compound provides an anti-fouling layer with 10mg / m <2> to 500mg / m<2> of solid content containing a polyfluorosilicone acrylic acid series comb-shaped graft copolymer. The anti-fouling film can be used to serve as a protective film in liquid crystal display assemblies, and has good anti-fouling and antistatic performances, chemical resistance and ink mark resistance.

Description

technical field [0001] The invention relates to an antifouling film, in particular to an antifouling film which can simultaneously have good antifouling property and ink marking property. Background technique [0002] The liquid crystal display device is mainly an optical device composed of five components: a backlight module, a polarizer, a glass substrate, a liquid crystal layer and a color filter. Among them, the polarizer is to convert the natural light that is generally not polarized into polarized light. The liquid crystal display uses this polarized light, coupled with the twisting characteristics of liquid crystal molecules, to achieve the purpose of controlling whether the light passes or not. In the process of making liquid crystal panels, two polarizers must be used, and the upper and lower polarizers must be arranged at a specific direction and angle depending on the polarization direction, so that the polarized light generated by the first polarizer can pass thr...
