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.
