Abstract
The utility model discloses a high temperature resistant aluminum foil label, which comprises a bottom paper layer, a back glue layer, a base material layer and a high temperature resistant printable coating; wherein, the substrate layer is an aluminum foil with the thickness of 50um, the upper surface of the substrate layer is provided with a uniform high-temperature resistant printable coating with the thickness of 10um-30 um; and gluing the lower surface of the substrate layer to form a back glue layer with the thickness of 30-70 um, and adhering a bottom paper layer on the lower surface of the back glue layer. The high-temperature-resistant printable coating on the upper surface of the high-temperature-resistant aluminum foil label can optimize the high-temperature resistance of an aluminum foil base material, the high temperature resistance can reach 370 ℃, meanwhile, the high-temperature-resistant printable coating has printing and printing performances, and the base paper layer on the lower surface of the high-temperature-resistant aluminum foil label can keep the activity of adhesive molecules of a back adhesive layer, so that the initial adhesion and the adhesive holding performance of the base paper layer are good. In addition, the label has good water resistance, solvent resistance, acid and alkali resistance and weather resistance.
Description
Technical Field
The utility model relates to a sign label technical field, in particular to high temperature resistant aluminium foil label.
Background
In the industrial production process, many places need to carry out information identification on products, such as the processes of warehousing and selling of the products and the like. And the industries such as steel, metallurgy and the like need to stick labels in a high-temperature environment, for example, large-specification round steel and other slow heat dissipation industrial products, and the requirement on the high-temperature resistance of the labels is higher.
The general labels are made by sticking paper or punching identification contents on painted metal sheets, and the labels have poor high-temperature resistance, are easy to corrode under natural conditions, damage the identification contents and even damage the labels. Therefore, a high temperature resistant label suitable for a long-time high temperature environment is needed.
Disclosure of Invention
The utility model aims at the weak point of above-mentioned conventional art, provide a high temperature resistant aluminium foil label.
In order to overcome the technical problem, the utility model discloses a technical scheme is:
a high temperature resistant aluminum foil label comprising: the base paper layer, the back glue layer, the base material layer and the high-temperature-resistant printable coating;
the substrate layer is an aluminum foil, and the thickness of the substrate layer is 50 um; coating on the upper surface of the film, and arranging a uniform high-temperature-resistant printable coating with the thickness of 10-30 um; gluing the lower surface of the base material layer to form a back glue layer with the thickness of 30-70 um; and a bottom paper layer is adhered to the lower surface of the back glue layer.
The back adhesive layer is a pressure-sensitive adhesive synthesized by taking polydimethylsiloxane as a main peroxide as a catalyst.
The high-temperature-resistant printable coating is a modified acrylic resin coating, and the thickness range is 10-30 um.
The base paper layer is release paper or release film.
The high-temperature-resistant printable coating is used for carrying out silk-screen printing, gravure printing, embossing printing, bar code printing or offset printing according to the application occasions of the labels.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses a high temperature resistant printable coating of high temperature resistant aluminium foil label upper surface can optimize the high temperature resistance ability of aluminium foil substrate, and high temperature resistant can reach 370 ℃, makes it possess simultaneously and prints and printing performance.
2. The utility model discloses a high temperature resistant aluminium foil label is waterproof, solvent-resistant, acid and alkali-resistance, weatherability good.
3. The utility model discloses a high temperature resistant aluminium foil label is printed and is printed effectually, and printing ink adhesive force is strong.
4. The utility model discloses a ground paper layer of high temperature resistant aluminium foil label lower surface can keep the gluing molecule activity of gum layer, and just viscidity and hold viscidity are good, can not descend after long-time the use viscidity and can stick more firmly on the contrary, the long-time storage of the article of being convenient for traces to the source. Meanwhile, the utility model can be protected from the external environment and is convenient for release.
