Abstract
The invention discloses an anti-adhesion double-faced hardened membrane and a preparation method thereof. The double-faced hardening membrane comprises a substrate, a 3H hardened layer coated on one side of a substrate surface, and an AB hardened layer coated on the other side of the substrate surface. The preparation method comprises the following steps: coating the 3H hardened layer and the AB hardened layer on the two sides of the substrate surface after all components of the two layers are uniformly mixed respectively; ultraviolet curing after drying. According to the invention, silicon dioxide powders with a grain diameter of 10 nm-800 nm are added into the AB hardened layer of the substrate, and wetting dispersants containing acid pigment affinity groups are adopted in order to enable nano silicon dioxide to disperse better; meanwhile, modified polysiloxane auxiliaries are added to ensure that part of nano silicon dioxide particles float on the surface of coatings, so that a better anti-adhesion effect of the double-faced hardened membrane is guaranteed, and optical properties of the coatings are not affected.
Description
Technical field
The present invention relates to cured film technical field, relate to particularly a kind of two-sided cured film with resistance to blocking and preparation method thereof.
Background technology
Existing touch-screen generally adopts plating tin indium oxide as conductive layer (ITO:Indium Tin Oxides, indium tin oxide), and its carrier is glass or optics PET(polyethylene terephthalate) film.Conventionally optics PET film surface hardness is lower, is generally HB, for wearing quality, considers, need carry out hardening treatment to PET two sides, makes surface hardness be increased to 2H～3H.The subject matter existing is at present that PET two sides all scribbles hardened layer, and during rolling, hardened layer is mutually stacked together, on the one hand, owing to forming vacuum closed state between film, is difficult for separately; On the other hand, there is a large amount of molecular chains that exposes on hardened layer surface, and the mutual winding between the closely sealed rear generation macromolecular chain of two hardened layers, places the easy adhesion of the two-sided hardened layer of PET for a long time, causes film impaired serious, affects follow-up deep processing.
In prior art, the technology that reaches antiblocking effect by interpolation particulate is nearly following several:
(1) Chinese invention patent that publication number is 103172987A " antiblocking masterbatch and preparation method thereof for a kind of optics basement membrane ", propose to add in the production of polyester film median size between the crosslinked particulate of polystyrene type of 1～20 μ m or polymethylmethacrylate particulate to reach the effect of antiblocking;
(2) Chinese invention patent that publication number is 102211436A " a kind of Anti-blocking film with high hardness and manufacture method thereof ", proposition is in the one side of polymer basic unit, formation contains the UV-cured coating that mean particle size is the colloid silica of 0.01～0.05 μ m, has excellent antiblocking characteristic while making film axis volume.
The method that above-mentioned patent provides is mostly to adopt to add the antiblocking performance that antiblocking agent improves coating.Above patent has just set forth PET basement membrane or how PET one side coating reaches antiblocking performance, but the elaboration of the blocking action producing while not relating to the rolling of PET coated on both sides.The antiblocking agent major part that currently available technology adopts is for PET one side hard coat, and because the another side process of PET base material is processed, so antiblocking effect is excellent.And poor for the film antiblocking effect of two-sided hardening treatment, the easy adhesion of the two-sided hardened layer of PET after permanent placement, causes film impaired serious.If antiblocking particulate is all added on basic unit two sides, certainly will increase cost.If only add antiblocking agent in a finishing coat of base material, when when rolling, two sides hardened layer is stacked together, antiblocking effect is poor, and excessive interpolation particle can cause again mist degree higher, affects the optical property of coating.
Summary of the invention
In view of this, the object of the invention is to prior art to improve, two-sided cured film of a kind of anti and preparation method thereof is provided, while making cured film stacked together, can slide, the blocking action while reducing rolling, plays the effect of antiblocking.
For solving the above-mentioned problems in the prior art, the present invention carries out hardening treatment in the one side of PET base material, improves coatingsurface hardness to 3H, can prevent that PET coating is by scratch; And the another side of PET base material adds some nano-powders in formulation for coating material, under ultraviolet lighting, harden, form anti (Anti-Blocking is called for short AB) cured film.There is part particle projection on this AB layer surface, increased like this space between AB hardened face and high rigidity hardened face, reduced the vacuum tightness between coating, while making AB layer and hardened layer stacked together, can slide, blocking action while reducing rolling, can meet the performance requriements of ito thin film high rigidity, high-penetration and low haze again simultaneously.
Concrete, the two-sided cured film of anti of the present invention, comprise base material, (one side of base material is carried out after hardening treatment hardness in the coating of 3H to be coated on the 3H hardened layer of described base material one side surface, be called for short in full 3H hardened layer) and (another side of base material carries out playing after hardening treatment the Anti-Blocking coating of antiblocking effect to be coated on the AB hardened layer on described base material opposite side surface, be called for short in full AB hardened layer), according to mass fraction meter, described 3H hardened layer comprises following component:
