Problems solved by technology

[0004] The purpose of the present invention is to provide a production process of antibacterial, environmentally friendly and anti-counterfeiting aluminum foil paper. By compounding a layer of isolation layer on the surface of the aluminum foil layer, and then compounding the paper base layer on the surface of the isolation layer, since the polyethylene oxide in the isolation layer is extremely It is easy to dissolve in hot water. By soaking the aluminum foil in hot water, the aluminum foil layer and the paper base layer can be separated through the dissolution of polyethylene oxide. The separated aluminum foil layer can be directly reused, which is not only easy to recycle, but also saves costs. In addition, no pollutants will be generated during the recycling process to achieve environmental protection performance. At the same time, the recycled aluminum foil layer still exists in the form of aluminum foil and can be used directly without additional processing, reducing costs and processes, thereby solving the problems in the prior art. Aluminum foil paper is usually discarded directly after use, or it is crushed and then dissolved with acid-base paired aluminum foil, and then the dissolved aluminum ions are recovered. The recovery process is complicated, the cost is high, and it is easy to produce acid-base waste. liquid, the problem of polluting the environment

Embodiment 1

[0023] The concrete preparation process of antibacterial discoloration colloid is as follows:

[0024] Step 1: Weigh 1 kg of pentanedione and add it to the reaction container, add 6 L of ethanol solution to it at the same time, stir and dissolve it, then add sodium hydroxide dropwise therein to adjust the pH of the solution to 13, and then add 560 g of acrolein to the reaction container, Stir the reaction at room temperature for 5-6 hours, then heat to 70°C and evaporate for 4-5 hours to remove the ethanol solvent and unreacted acrolein, then add dilute hydrochloric acid to the obtained product dropwise to adjust the pH of the product to 7, then adjust the acidity The adjusted product was extracted with ether, and the upper oil phase was collected and then subjected to vacuum distillation to obtain dialdehyde diketone;

[0025] Step 2: Weigh 1 kg of 2,4-dinitrophenylhydrazine and add it to 10 L of acetic acid solution, cool it down to 5-10° C. and stir to dissolve, then add 65...

Abstract

The invention discloses a production process of anti-bacterial environment-friendly anti-counterfeiting aluminum foil paper. The process specifically comprises the steps that waste paper is smashed and then is added into a sodium hydroxide solution to be soaked to obtain paper powder; the paper powder is added into anti-bacterial color changing colloid to obtain color changing gelling paper pulp;a certain amount of polyethylene oxide is weighed, and is melted at the temperature of 70 DEG C, and sprayed to the surface of an aluminum foil layer while it is hot, at the moment, an isolation layeris formed on the surface of the aluminum foil layer, the prepared color changing gelling paper pulp is evenly coated on the surface of the isolation layer, and anti-bacterial anti-counterfeiting aluminum foil paper is obtained. The isolation layer is compounded on the surface of the aluminum foil layer, a paper base layer is compounded on the surface of the isolation layer, due to the fact that polyethylene oxide in the isolation layer is prone to be dissolved in hot water, the aluminum foil paper is soaked in hot water, through dissolving of polyethylene oxide, separation of the aluminum foil layer and the paper base layer is achieved, the separated aluminum foil layer can be directly recycled, recycling is easy, cost is saved, and in the recycling process, no pollutant is generated.

Description

technical field [0001] The invention belongs to the field of aluminum foil paper preparation, and relates to a production process of antibacterial, environment-friendly and anti-counterfeiting aluminum foil paper. Background technique [0002] Aluminum foil paper is widely used in the packaging field. When it is lower than the packaging of high-end products, it is difficult for consumers to distinguish the authenticity of the product, and aluminum foil paper is generally made of aluminum foil and paper layers. The paper layer is in a humid environment. It is easy to breed bacteria and fungi and become moldy. Therefore, in the prior art, bactericidal substances are usually added directly to the pulp. In the existing bactericidal substances, heavy metal ions or quaternary ammonium salt cationic groups are usually introduced into it, but heavy metal ions are usually absorbed by adsorption. The load is easy to desorb under certain conditions, reducing its effect, and at the same...
