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 effects of the invention, but the present invention is not limited thereto.
Surface antisticking paster
In a first aspect, the present invention provides a sticker for releasing a surface. In the first embodiment of the present invention, as shown in fig. 1, the surface release sticker a of the present invention comprises an adhesive layer 1, a base material layer 2, a pattern layer 3, a matte film layer 4, and a release layer 5, which are stacked.
In the sticker a with a release-resistant surface according to the present invention, the adhesive layer 1 is provided on the first side surface of the base material layer 2, and is used to easily attach the sticker a with a release-resistant surface according to the present invention to a desired position. The adhesive layer 1 can be made of any material having an adhesive effect, such as double-sided tape.
In the surface antisticking paster A, the substrate layer 2 has the characteristics of high density and good stiffness and mainly plays a role in supporting. The material of the base material layer 2 is preferably synthetic paper, and more preferably has a density of not more than 0.8g/cm2The synthetic paper (e.g., 300 g or 350 g hard pearl synthetic paper) of (2) can provide the substrate layer 2 with a high rigidity because of its low specific gravity.
Further, the first side surface and/or the second side surface of the base material layer 2 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 can not be folded after being bent, and better ink adhesion can be realized when the base material layer 2 is sprayed and printed with patterns. The invention has no special requirement on the film coating liquid, and only the dyne value of the coating liquid coated on the surface of the material reaches more than 40. In practice, the skilled person will be able to select them as required.
Further, the second side surface of the substrate layer 2 may be subjected to corona treatment, so that the surface tension coefficient of the substrate layer 2 is greater than or equal to 40 dyne/cm, and the printability (i.e., ink adhesion) of the substrate layer 2 is further enhanced.
In the sticker a with the anti-sticking surface of the invention, the pattern layer 3 is arranged on the second side surface of the substrate layer 2, and can be an ink pattern, for example, a sun-proof ink is adopted, and the color of the sticker a can not fade after being illuminated for more than three years under normal illumination. Any commercially available sunfast ink can be used in the surface release sticker of the present invention.
In the surface release sticker a of the present invention, the dummy film layer 4 covers the pattern layer 3 for bonding the release layer 5 and the pattern layer 3. The matte film layer 4 is an adhesive film with super-strong viscosity, and after being compounded with the pattern layer 3 and the base material layer 2, the lamination of the sticker and the surrounding whitening (so-called whitening, or printing whitening, which means that white spots appear on the printing surface due to insufficient adhesive force between ink and printing substances in printing) caused by weak viscosity can not occur. And, the surface tension coefficient of the matte layer 4 is 40 dyne/cm or more, so that the adhesion of the anti-sticking layer 5 is good when the anti-sticking layer 5 is provided thereon. Preferably, the matte film layer 4 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 product. 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.
In the surface release sticker a of the present invention, the release layer 5 covers the matte film layer 4, which has a release effect that when a sticker with glue is attached to the surface of the release layer 5, the sticker is easily torn off or easily drops off by itself. The releasing layer 5 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 silicone oil and the acid-base resistant additive which are generally commercially available can be used in the invention. Because the silicone oil content is high, the surface of the anti-sticking layer 5 is very smooth, so that the anti-sticking effect is very good, and meanwhile, the effects of acid and alkali resistance, oil resistance and water resistance can be realized.
At present, a silicone oil film is usually arranged on a base material of a film with an anti-sticking effect in the market, but the use requirement is often not met, and the main performance is that the film is not strong in viscosity and easy to bubble, and the silicone oil film is easy to fall off from the base material when the film is used for a long time. In the sticker with the anti-sticking surface, the anti-sticking layer 5 and the dummy film layer 4 are respectively adopted, the anti-sticking layer 5 is used for preventing sticking on the surface, and the dummy film layer 4 is used for firmly sticking the anti-sticking layer 5 on a substrate.
When the dummy film layer 4 is arranged, the corona treatment is carried out on the dummy film layer 4, the surface tension coefficient is more than or equal to 40 dyne/cm, which mainly makes the surface of the dummy film layer 4 uneven, so that the contact area is increased, the unit area usage of the chemical reagent of the anti-sticking layer 5 on the dummy film layer after the corona treatment is larger than that on the dummy film layer without the corona treatment, the usage is increased, but the surface height is not increased (the height is increased, but the height is increased, the coating is easy to become brittle and easy to fall off after long time), thus, through the irradiation of the UV light source, the light source can well penetrate the reagent layer (namely the anti-sticking layer 5), the reagent can fully react with the dummy film through heat, so that the occlusion is better, the anti-sticking layer 5 is dry and more thorough, the curing effect of the anti-sticking layer 5 is better, thereby achieving the effect of avoiding bubbling and shedding. In addition, the anti-sticking layer 5 has high silicone oil content, and after sufficient time leveling and proper light intensity, a very smooth silicone oil layer is formed on the surface, and the silicone oil does not react with oil, water, acid, alkali and the like, so that the effects of acid and alkali resistance and easy falling off after other non-setting adhesives are stuck on the silicone oil layer are achieved. And, optionally, the release layer 5 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 5 and the dummy film layer 4 respectively, not only can an excellent anti-sticking effect be achieved, but also the problems of bubbling and shedding can be avoided.
Alternatively, in order to protect the adhesive layer before the surface-antisticking sticker is adhered to a target site, as shown in fig. 2, in a second embodiment of the present invention, the surface-antisticking sticker a' of the present invention further includes a base paper layer 6 disposed on a surface of the adhesive layer on a side away from the base material layer. The base paper layer 6 may be a paper with one side surface being release-resistant, such as a release paper.
In the surface release sticker a' of the present invention, both the adhesive layer 1 and the base paper layer 6 are commercially available, and for example, the adhesive layer 1 and the base paper layer 6 may be a double-sided adhesive tape of type 3M-55236 compounded together at the time of purchase.
The invention has no special limit on the thickness of each layer of the sticker with the anti-sticking surface and the length and the width of the sticker, and the sticker can be reasonably set by a person skilled in the art according to the needs when in actual use.
In the case of using the sticker A' with a surface release agent of the present invention, the base paper layer 6 is removed, and then the sticker is stuck to a target position with the adhesive layer 1 facing the target position.
Preparation method of sticker with anti-sticking surface
In a second aspect, the invention provides a method for preparing a sticker with a release-resistant surface, which comprises the following steps: performing corona treatment on one side surface of the substrate layer 2; a preset pattern forming pattern layer 3 is arranged on the surface of one side of the base material layer 2 which is subjected to corona treatment; coating glue on the pattern layer 3 to form a dummy film layer 4; coating gloss oil on the matte film layer 4, and drying to form an anti-sticking layer 5; and an adhesive layer 1 is provided on the other surface of the base material layer.
Optionally, in order to protect the adhesive layer 1 before the sticker with the surface anti-sticking property is pasted on a target position, the preparation method of the invention further comprises the step of arranging a base paper layer 6 on the surface of the adhesive layer 1 far away from the base material layer. And optionally the adhesive layer 1 and the base paper layer 6 are provided simultaneously.

By the corona treatment, particularly, by using a power higher than a conventional corona treatment power (about 1.6 kw), the surface tension of the side surface of the base material layer 2 can be increased, thereby increasing printability and preventing ink drop, film peeling, and the like.
S103, setting a pattern layer: a predetermined pattern formation pattern layer 3 is provided on the corona-treated side surface of the base material layer 2. Specifically, the preset pattern may be set by printing and/or code spraying.
