| titleOfInvention | Manufacturing method of antistatic coating composition for PET sheet |
| abstract | The present invention relates to a method for producing an antistatic coating composition for PET sheets, based on 1,000 to 1,100 parts by weight of distilled water, as an emulsifier, sodium-di-2-ethylhexyl sulfosuccinate 2 ~ 3 parts by weight to a first reactor to prepare a dispersion medium, the first step of raising the internal temperature of the reactor to maintain at 85 ~ 86 ℃; 135 to 145 parts by weight of ethyl acrylate (EA) as a monomer for synthesis in the second reactor, 100 to 105 parts by weight of methyl methacrylate (MMA), 95 to 100 parts by weight of styrene (SM), methacrylic acid (MAA) 30 2 to 40 parts by weight, and 4 to 5 parts by weight of N-dodecyl mecaptan (n-DM) as a chain transfer agent and uniformly mixed to prepare a monomer mixture; The solution prepared by dissolving 4.5-5.5 parts by weight of ammonium persulfate (APS) as a polymerization initiator in 20-25 parts by weight of the dispersion medium prepared in the first reactor and distilled water was added to a third reactor having an internal temperature of 85-86 ° C., and then A third step of uniformly dropping the monomer mixture prepared in a reactor for 100 to 200 minutes to produce a white emulsion polymer; While maintaining the temperature of the third reactor at 75 ~ 80 ℃ by adding ammonia water to react methacrylic acid and ammonia water to replace the water-soluble resin, and then 100 ~ 120 parts by weight of the distilled water prepared separately to cool the third reactor A fourth step of preparing a water-soluble acrylic binder (Acryl-200B); 450-500 parts by weight of distilled water and 100-120 parts by weight of water-soluble acrylic resin binder (Acryl-200B) were mixed in a reactor equipped with a separate mixing stirrer and mixed uniformly, followed by N-methylpyrrolidone ( NMP) 70 ~ 90 parts by weight, 250 ~ 300 parts by weight of isopropyl alcohol (IPA) is added to form a homogeneously mixed mixture, PEDOT / PSS {Poly (3,4-ethylenedioxythiophene) poly (styrenesulfonate)} 150 to 180 parts by weight and additionally mixed to form a dark blue viscous liquid to prepare a fifth step, the third reactor for the complete synthesis of unreacted monomer when the addition of the monomer in the third step is finished The temperature is maintained at 85 ~ 86 ℃ and further characterized in that the aging reaction for 100 to 200 minutes. In addition, the fourth step is to accept the polymer resin in the form of emulsion, mixing 100 to 110 parts by weight of distilled water with 28 to 30 parts by weight of ammonia water at a concentration of 25% by volume and adding diluted ammonia water for 20 to 40 minutes. Characterized in that, the antistatic coating composition for PET sheet produced by the present invention is a dark blue viscous liquid, characterized in that the solid content of 2.2 ~ 2.5%, pH 4 ~ 5. The antistatic coating composition for PET sheet manufactured by the present invention is manufactured by using an acryl resin that is accommodated to improve compatibility with PEDOT / PSS, which is a water-dispersible conductive polymer, to improve adhesion and minimize solvent usage during the process. It is environmentally friendly because it can suppress the generation of fugitive solvents generated. Especially, water-soluble acrylic resins developed as binders are water-dispersible in the manufacturing process, water-soluble in the coating composition, and dried after being applied to the sheet. If there is a strong adhesive force and durability, there is an effect of forming a film having excellent antistatic properties. And the method of manufacturing the antistatic coating composition for PET sheets, since the characteristics of the conductive polymer used is a strong acid, when mixed with a binder and other additives must be neutralized using a suitable neutralizing agent, but the acrylic developed in the present invention Since the resin binder is substituted with alkali, there is an advantage that a separate neutralization step is not necessary. |
