Description
Technical field
The present invention relates to the preparation method of a kind of UV coating, coating and coating; a kind of coating for the preparation of anti-dazzle, antistatic, antifouling coating particularly; the preparation method of coating and coating, prepared coating can be widely used in the fields such as all kinds of contactor control devices, electronics form, material surface protection.
Background technology
Along with American apple company with the iPhone mobile phone belt to after the world, the fast development of electronic touch technology, smart mobile phone, the various Pad that occurred in recent years just leading electronic product and household electrical appliance towards the future development of touch control, and computer is also just towards truly touch control future development.
Touch-screen needs ceaselessly by finger contact, and the grease on the finger, sweat and koniology are easy to be stained with on the screen, thereby has affected sharpness, the reduction reading property of screen.The effect of antifouling in order to play (anti-fingerprint); usually can in UV coating, add siliceous or fluorine-containing auxiliary agent or resin; coating with such coating preparation can have certain antifouling (anti-fingerprint) effect; the water contact angle of inventing such as patent CN101299073B is at 100-110 °, and the contact angle of water is greater than 80 ° in the disclosed patent of CN102634267.Yet all ignored such problem in most of patent, that is exactly concrete silicone content and fluorine content in siliceous, fluorine-containing auxiliary agent or the resin, and the position of these compositions in molecule segment.Our work is found, when silicone content or fluorine content are too low, need to add siliceous or fluorine-containing auxiliary agent or the resin of higher proportion, otherwise antifouling (anti-fingerprint) effect is relatively poor, and tends to have influence on other performances of coating when adding higher proportion; If but the silicone content of the siliceous or fluorine-containing auxiliary agent that adds or resin or fluorine content compatibility problem can occur when higher, have influence on equally the performance of coating.As seen, controlling silicone content and the fluorine content in fluorine-containing auxiliary agent or the resin that contains in silicon additive or the resin well is very important to the coating that preparation has well antifouling (anti-fingerprint) effect.And silicon, fluorine composition on short-chain branch during dense distribution antifouling (anti-fingerprint) effect of coating better than on main chain the time.In addition, general coating is difficult to eliminate after producing static, is easy to adsorb the decline that dust causes antifouling (anti-fingerprint) effect.Thereby to realize long-acting and anti-fouling (anti-fingerprint) effect, coating has certain static resistance and also is absolutely necessary.
If display screen is easy to occur the dazzling situation of dazzle in light direct projection situation, screen is not easy to see clearly literal, image above the screen, so generally all can carry out anti-dazzle and processes when allowing as much as possible display equipment reach comparatively soft display effect.The method of general realization anti-dazzle effect mainly is by the interpolation particle, has realized anti-dazzle effect of light such as CN101299073B by adding anti-dazzle particle, and CN1540365A provides a kind of organic particulate prepares antiglare film in conjunction with the inanimate matter particulate method.Yet the particle aggregation phenomenon is serious, difficulties in dispersion, and the coating homogeneity of preparation is relatively poor also unstable, and the anti-dazzle effect of gained film also can be affected.
It is found that also have the micro-nano structure of newborn convex except the Wax on surface by the research to lotus leaf surface, this micro-nano structure has improved the hydrophobic property of lotus leaf.According to this principle, can improve by the micro-rough degree that improves material surface the surface to the contact angle of water.When material surface was uneven, different optical effects can occur through out-of-date in light.When this concavo-convex yardstick during less than 100nm, anti-reflection effect (A.Nakajima, A.Fujishima, K.Hashimoto, etal.Adv.Mater., 1999,11,1365. are arranged; H.Yabu, M.Shimomura, Chem.Mater., 2005,17,5231.), and along with the increase of concave-convex surface yardstick, light will change diffuse-reflectance into by specular reflection on shining coating the time, so that light is so not dazzling, that is to say that certain surfaceness also can play the anti-dazzle effect.Thus, the certain surfaceness of control not only is conducive to hydrophobic raising but also can plays the anti-dazzle effect.And can well realize control to coating surface structure by technology such as roller coat, transfer printings, and be fit to very much industrialization and produce continuously.
