Embodiment 1

[0063] 1-1. A thermosetting antistatic material was produced by mixing: 10% by weight of polyethylene (3,4-ethylenedioxythiophene) (Baytron, PH), 5% of acrylic-amino Potassium ester polymer (Stahl Asia Pte Ltd., WF-4644), 31.5% water, 50% isopropanol, 3% 1-methyl-2-pyrrolidone and 0.5% slip agent (silicon resin series ).

[0064] 1-2. Using an extruder at 170-190°C, and through the T-plate pressing process, the polypropylene resin is extruded, and then passed through an embossing roll, a polishing roll or a cooling roll to produce an embossed Layer 0.5mm thick polypropylene gasket, and then apply the above thermosetting antistatic material with a thickness of 0.1μm (coating film after drying) on ​​one side surface of the above polypropylene gasket by gravure printing coating method, And carry out thermosetting treatment at a temperature of 60-80°C, and apply thermosetting antistatic material and thermosetting treatment on the reverse side in the same way to manufacture antist...

Embodiment 2

[0067] 2-1. A light-hardening nano hardening substance is produced by mixing the following substances: by weight percentage, 50% acrylic unit (20% polydipentaerythritol hexaacrylate, 30% pentaerythritol triacrylate, Korea Miwon business), 10% of the alkyl-alkoxy acrylic unit [poly-dipentaerythritol hexaepoxyacrylate (Dipentaerythritol hexaetoxyacrylate: DPHEA), SATOMER Co.)], 25% of the inorganic oxide---water-dispersed silicon Stone sol (Nalco 2327, NALCO Co.), 5% silane compound [3-methacryloxypropyltrimethoxysilane, (3-methacrylocxa propyl trimethoxy silane), Shin-etsu chemical Co.], 10% A mixture of gum stabilizers (acryloyl morpholine, SATOMERCo.).

[0068]2-2. Add the following substances to produce a light-hardening antistatic material: by weight percentage, 15% of the light-hardening nano-hardening substance produced in the above-mentioned 2-1 step, 10% polyethylene (3,4-B Dioxythiophene) (Baytron PH, Bayer Co.), 1% photoinitiator (Igacure 184, Ciba Geigy Co.), 0.2% s...

Embodiment 3

[0071] 3-1. A thermosetting antistatic material is produced by mixing the following components, 2% of carbon nanotubes (MWCNT, Nanocyl), 5% of acrylic acid-potassium urethane polymer (Stahl Asia Pte Ltd., WF- 4644), 42.5% water, 50% isopropyl alcohol, 0.5% slip agent (silicon resin series).

[0072] 3-2. Except for the method of producing thermosetting antistatic material in the above step 3-1, adopt the same method as the above Example 1 to produce an antistatic gasket for lamination of beverage and food containers.

Abstract

The invention relates to an anti-static gasket for stacking beverage and food containers and a manufacturing method thereof. The anti-static gasket comprises an insulator film, an embossed layer formed on at least one side surface of the insulator film, and an anti-static layer on the other side, opposite to the side connected with the embossed layer, of the insulator layer. The manufacturing method of the anti-static gasket for stacking beverage and food containers includes the steps of manufacturing the insulator film by extruding an ethylene series high polymer material; enabling the insulator film to pass through an embossed roll to form the embossed layer on at least one side surface of the insulator film; coating an anti-static material on the other side, opposite to the side connected with the embossed layer, of the insulator layer to form the anti-static layer. By the aid of the anti-static gasket, phenomena strikes among the containers, foreign material adhering caused by static, tiny dust pollution and surface scraping and the like can be effectively avoided, sliding phenomenon of the food containers can be reduced to the largest extend, and the stacked containers can be separated conveniently.

Description

technical field [0001] The invention relates to an antistatic gasket for lamination of beverage and food containers and a manufacturing method thereof. Through the antistatic gasket for stacking beverage and food containers and its manufacturing method in the present invention, it is possible to effectively prevent contact between containers, foreign matter sticking caused by static electricity, and fine dust when packaging and transporting beverage and food containers. Contamination and surface scratches, etc., and can minimize the sliding phenomenon of food containers, and facilitate the separation of stacked containers. In addition, the curling phenomenon of the antistatic gasket in the present invention is almost zero. Background technique [0002] In the process of manufacturing, packaging, and transporting beverage and food containers, insulating paper cut into discs for lamination gaskets used to support or protect containers is generally used. However, the above-me...
