And because the coating amount of the glue is reduced and the weak-glue is adopted, the peeling force of the label paper from the rolled aluminum foil is reduced, and the condition that the label paper is smoothly peeled from the aluminum foil without tearing the rolled aluminum foil can be met.

Embodiments of the present application will be further described with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present application provides a label sticker 100 including a protective layer 20 and a label paper 10, wherein the label paper 10 is used for sealing and fixing a roll-shaped aluminum foil 201.

The rolled aluminum foil 201 has a winding end and a pasting region, and the winding end partially overlaps the pasting region in the circumferential direction of the rolled aluminum foil 201. The seal of the rolled aluminum foil 201 is fixed, that is, the relative positions of the winding end and the pasting region are fixed, and the movement of the winding end relative to the pasting region is prevented, so that the rolled aluminum foil 201 is maintained in a wound state. The label paper 10 needs to be torn off when the roll-shaped aluminum foil 201 needs to be used. By the structure of the label paper 10, the roll-shaped aluminum foil 201 can be opened without tearing the roll-shaped aluminum foil 201 as much as possible when the label paper 10 is torn off.

It is understood that the label paper 10 may also be used for sealing and fixing other products such as a plastic wrap, a plastic bag, and the like, and is not limited herein.

Referring to fig. 2, the label paper 10 includes an adhesive layer 16 and a base layer 17, and glue is uniformly coated on the base layer 17 to form the adhesive layer 16. The glue is weak glue, and the weak glue is glue with the peel strength of less than 20 MPa.

In one embodiment, the glue is a silicone glue. The peeling strength of the silica gel glue is generally about 18 MPa. Compared with epoxy adhesives, polyurethane adhesives, acrylic adhesives and the like, the silica gel glue has weaker bonding force.

The silica gel glue can be prepared by the following method:

according to the mass parts, the silica gel glue is prepared by mixing 90-120 parts of silica gel resin, 0.5-2.5 parts of cross-linking agent, 1-5 parts of anchoring agent, 1-3 parts of catalyst and 90-120 parts of solvent.

Wherein the cross-linking agent is hydroxyl silicone oil, such as Dow 7028.

The anchoring agent comprises one or a combination of more of gamma-aminopropyltriethoxysilane, gamma-glycidoxypropyltrimethoxysilane, gamma- (methacryloyloxy) propyltrimethoxysilane, N- (beta-aminoethyl) -gamma-aminopropylmethyldimethoxysilane, gamma-glycidoxypropylmethyldiethoxysilane, vinyltriethoxysilane, vinyltrimethoxysilane and vinyltris (beta-methoxyethoxy) silane. Preferably, the anchoring agent is a combination of gamma-aminopropyltriethoxysilane, gamma-glycidoxypropyltrimethoxysilane, gamma- (methacryloyloxy) propyltrimethoxysilane. Such as the dow 303 model product.

The catalyst adopts a platinum catalyst; such as the platinum catalyst Pt 4000.

The solvent is 120# solvent oil and ethyl acetate, and the weight percentage is 70: 20-40 by mixing.

In one embodiment, the base layer 17 is a plastic film, which is a non-polar polymer and has a low surface tension of 29 to 30mN/m, and theoretically, if the surface tension of an object is less than 33mN/m, the silica gel glue is difficult to adhere to the surface firmly, and the surface is treated by a corona method. The processing principle is that high-frequency and high-voltage electricity is applied to processing equipment to generate high-frequency and high-voltage discharge and generate fine and dense violet-blue sparks. Various ions generated after air ionization accelerate and impact the plastic film in the label sticker 100 under the action of a strong electric field. The chemical bonds of the plastic molecules are broken and degraded, and the surface roughness and the surface area are increased. During discharging, a large amount of ozone is generated, which is a strong oxidant and can oxidize plastic molecules to generate groups with stronger polarity, such as carbonyl, peroxide and the like, so that the surface energy of the plastic is improved. The surface of the base layer 17 is corona-treated at a high voltage to increase its surface roughness and surface area and to increase its surface energy. Thereby make silica gel glue can comparatively firmly adhere to on plastic film.

And uniformly coating the prepared silica gel glue on one surface of the treated base layer 17, and then putting the base layer into a curing chamber for curing to obtain the label paper 10 with the bonding layer 16.

Optionally, the coating weight of the silica gel glue is 1-3 g/square meter.

The coating weight of glue of a label sticker 100 product commonly used in the market at present is 6-8 g/square meter, and compared with the coating weight of glue of a label sticker 100 product commonly used in the market, the coating weight of the silica gel glue in the embodiment is reduced, and the cost is reduced. And because the coating weight of the liquid silica gel glue is reduced and the weak adhesiveness of the silica gel glue, the stripping force of the label paper 10 is reduced, so that the aluminum foil can be smoothly stripped without tearing the aluminum foil.

An important index parameter of the label paper 10 is peel strength, which is the force required to peel a pressure-sensitive adhesive tape having a certain width from the surface of a specific adherend, and the interfacial peel strength P, P ═ F/L, is calculated by testing the peel force F and the sample width L. The peel strength can be measured according to GB/T2792-2014 by using a YGJ-02A adhesive tape press rolling machine and an XLW (PC) intelligent electronic tension tester produced by Labthink blue light. The test environment temperature is 23 +/-2 ℃ and the relative humidity is 65% +/-5%. The adhered material is SUS304# stainless steel plate, the width of the adhesive tape is 25mm, and the peeling rate is 300 mm/min. Each sample was measured 3 times and the arithmetic mean was taken.

Example 1: uniformly coating the prepared silica gel glue on one surface of the treated base layer 17, and then placing the base layer into a curing chamber for curing to obtain the label paper 10 with the bonding layer 16, wherein the coating quantity of the silica gel glue is 1-3 g/square meter.

Comparative example 1: the preparation method of a label sticker 100 commonly used in the market is the same as that of example 1, and the coating amount of glue is 6-8 g/square meter.

The above label paper 10 was subjected to peel strength test, and the specific test results are shown in table 1:

table 1:

as can be seen from the above test data, the peel strength of the label paper 10 in this embodiment is lower than that of the conventional label paper 10, and the average peel strength of the label paper 10 in this embodiment is 2.454GF, while the tearing strength of the aluminum foil paper is 7 GF. The peeling force in this embodiment is smaller than the force for tearing the aluminum foil paper, so the label paper 10 in this embodiment can seal and fix the aluminum foil roll 200, and the roll-shaped aluminum foil 201 may not be torn when the aluminum foil roll 200 is opened by tearing the label paper 10.

In the present test, the width of the label paper 10 of the sample of the present embodiment is the same as that of the comparative example, so that the change in peel strength from that of the conventional label paper 10 can be obtained by comparing the peel forces.
