Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and functions of the present invention, but the present invention is not limited thereto.
The utility model provides an antiseized transparent film in surface, this transparent film can cover in order to play antiseized guard action on stickers such as advertisement or sign indicating number subsides. The transparent film with the anti-sticking surface comprises a substrate layer, a dummy film layer and an anti-sticking layer which are sequentially stacked; wherein, mute rete sets up between the first side surface of substrate layer and the second side surface of antiseized layer for bonding antiseized layer and substrate layer.
Optionally, in order to facilitate the fixation of the surface anti-sticking transparent film on the surface of the paster, the surface anti-sticking transparent film can further comprise an adhesive layer and a base paper layer; the adhesive layer is arranged on the second side surface of the base material layer; the base paper layer is arranged on the surface of one side, far away from the base material layer, of the adhesive layer and used for protecting the adhesive layer.
In the first embodiment of the present invention, as shown in fig. 1, the anti-sticking transparent film a includes an anti-sticking layer 1, a dummy film layer 2 and a substrate layer 3, which are stacked, wherein the dummy film layer 2 is disposed between the first side surface of the substrate layer 3 and the second side surface of the anti-sticking layer 1, and is used for bonding the anti-sticking layer 1 and the substrate layer 3.
In this embodiment, the release layer 1 has an anti-adhesive function, and when the sticker with glue is attached to the first side surface of the release layer 1, the sticker is easily torn off or easily drops off by itself. The anti-sticking layer 1 is made of gloss oil with high content of silicone oil, namely 25-35% (weight) (preferably 30%) of silicone oil and 8-13% (weight) (preferably 10%) of acid-base resistant additive are added on the basis of the formula of the conventional gloss oil, and the commercially available silicone oil and acid-base resistant additive can be used. Because the silicone oil content is high, the first side surface of the anti-sticking layer 1 is very smooth, so that a good anti-sticking effect can be realized, and meanwhile, the effects of acid and alkali resistance, oil resistance and water resistance can be realized.
In the present embodiment, the dummy film layer 2 is provided between the first side surface of the base material layer 3 and the second side surface of the release layer 1 for bonding the release layer 1 and the base material layer 3. Mute rete 2 is the glued membrane, after compounding with substrate layer 3, the sticker layering can not appear and play whitely on every side to mute rete 2's surface tension coefficient more than or equal to 40 dyne/centimetre, thereby make on it set up anti-sticking layer 1 when 1 adhesion force good of anti-sticking layer. Preferably, the matte film layer 2 can be made of UV reinforced composite glue, that is, a commercially available glue reinforcing agent is added to the commercially available glue and mixed to obtain the UV reinforced composite glue. For example, the UV glue purchased from shenzhen breuter ink coating limited and the UV glue purchased from shang heidson chemical industry limited are mixed with the glue reinforcing agent purchased from beijing chemical university, and in actual use, a person skilled in the art can select a proper ratio as required. One optional ratio range is: 45-60 percent (by weight) of UV glue purchased from Shenzhen Brute ink paint Limited, 20-35 percent (by weight) of UV glue purchased from Shanghai Dison chemical industry Limited and 5-20 percent (by weight) of glue reinforcing agent purchased from Beijing chemical university. Of course, it should be understood that the foregoing ratio ranges are merely exemplary, and in practice, one skilled in the art may select the glue, glue strengthener, and the ratio therebetween as desired. Furthermore, it should be noted that the glue and the glue enhancer are merely mixed together without any chemical reaction taking place between them.
In the present embodiment, the base material layer 3 is a transparent material having a supporting function, for example, a transparent polymer film. Conventional commercially available transparent polymer films can be used, such as polyethylene, polypropylene, polyethylene terephthalate, etc., and those skilled in the art can make reasonable selections as needed, and will not be described herein.
The first side surface and/or the second side surface of the base material layer 3 preferably has a UV coating layer. Different from the traditional water-based primer, the UV (ultraviolet) coating can realize very good printability, so that the composite film does not have crease after being bent. Different materials all have corresponding coating liquids, and the coating liquids can be obtained commercially, and the embodiment has no special requirements on the film coating liquid, and only needs the coating liquid to reach the dyne of more than 40 by coating on the surface of the material. In practice, the skilled person will be able to select them as required.
As mentioned above, the current films with anti-sticking effect on the market usually have a silicone oil film on the substrate, but this often fails to meet the requirement of use, mainly manifested by weak viscosity and easy bubbling, and the silicone oil film is easy to fall off from the substrate when used for a long time. In the antiseized transparent film in surface of embodiment, adopted antiseized layer 1 and mute rete 2 respectively, antiseized layer 1 is used for the surface antiseized, and mute rete 2 is used for the firm bonding of antiseized layer 1 on the substrate, through this kind of setting, can enough realize excellent antiseized effect, can avoid the problem of foaming and droing again.
Carry out corona treatment to dumb rete 2 when setting up dumb rete 2, this is mainly to make 2 surperficial unsmooth of dumb rete, thereby make area of contact increase, the unit area use amount of antiseized layer 1's chemical reagent on the dumb rete through corona treatment is bigger than the unit area use amount on the dumb rete that does not pass through corona treatment, the volume of using simultaneously has increased, but the surface height does not increase (highly increased can cause on the contrary because of the increase of height, the coating becomes fragile easily, it can drop easily to have lasted for a long time), so, through the shining of UV light source, the penetrating reagent layer that the light source can be fine (antiseized layer 1 promptly), the reagent can fully pass through the heat with dumb membrane and take place the reaction, thereby the interlock is better, and then antiseized layer 1 dry more thorough, the effect of antiseized. In addition, the silicon oil content of the anti-sticking layer 1 is high, after sufficient time leveling and proper light intensity, an ultra-smooth silicon oil layer can be formed on the surface, and the silicon oil does not react with oil, water, acid, alkali and the like, so that the effect of acid and alkali resistance and easy falling-off of other non-setting adhesives stuck on the silicon oil layer is achieved. And, alternatively, the release layer 1 may be subjected to corona treatment to have a surface tension coefficient of 40 dyne/cm or more and then coated with silicone oil, and the corona treatment can greatly increase the absorption amount of silicone oil, thereby contributing to further improvement of the release effect and also to permeation of UV light. Therefore, by adopting the anti-sticking layer 1 and the dummy film layer 2 respectively, not only can an excellent anti-sticking effect be realized, but also the problems of foaming and falling off can be avoided.
