| titleOfInvention | Cationic Antistatic Agent For PET Sheet Having Release Properties |
| abstract | The present invention relates to a cationic antistatic agent for PET sheet having a release property, the cationic antistatic agent for PET sheet of the present invention, to 100 parts by weight of the quaternary ammonium salt modified silicone oil represented by the following formula (1), A pale yellow transparent viscous liquid prepared by mixing 50 to 200 parts by weight of a cationic emulsifier of a quaternary ammonium salt and 300 to 400 parts by weight of water, wherein the nonvolatile content is 20 to 25% by weight and pH 4 to 5 . <Formula 1> (Wherein n is 180 to 220 and m is 4 to 6.) <Formula 2> In addition, the quaternary ammonium salt modified silicone oil, 120 weight of amino modified silicone oil having a refractive index of 1.40 ~ 1.42 (25 ℃ reference), amine equivalent 0.6 ~ 0.8 mg / g, viscosity 800 ~ 1,200 cPs (25 ℃ reference) 40 parts of emulsifier (LA-7) in which 7 mol of ethylene oxide was added to lauryl alcohol and 15 parts by weight of emulsifier (TDA-7) in which 7 mol of ethylene oxide was added to tridecyl alcohol were uniformly mixed in a main reactor. Preparing process; Preparing a solution in which 9 to 11 parts by weight of dimethyl sulfate (DMS) and 25 parts by weight of isopropyl alcohol (IPA) are uniformly mixed in a co-reactor; The solution prepared in the secondary reactor was added dropwise to the mixed solution prepared in the main reactor for 1 hour while maintaining the temperature of the main reactor at 60-65 ° C., followed by quaternization of the amino-modified silicone oil, followed by aging by raising the temperature to 70 ° C. Conducting the reaction for 1 hour; When the aging reaction is completed, the distilled water 300 to 500 parts by weight in the auxiliary reactor is prepared by maintaining the temperature at 50 ℃ while maintaining the temperature at 50 ℃ uniformly mixed for 1 hour. And the emulsifier consisting of the cationic surfactant of the quaternary ammonium salt, 150 parts by weight of the emulsifier (LM-2) and 2 parts of ethylene oxide added to laurylamine and 55 parts by weight of isopropyl alcohol (IPA) to the main reactor and the temperature Preparing a solution that is uniformly mixed while maintaining the temperature at 60 ° C; While maintaining the temperature of the main reactor at 60 ℃ constant dimethylsulfate (DMS) 55 ~ 70 parts by weight dropping for 2 hours while proceeding the quaternary cation reaction and the temperature is raised to 70 ℃ to produce a aging reaction for 60 minutes It is characterized by. The cationic antistatic agent for PET sheet of the present invention was imparted with the release property and antistatic function of silicon by quaternary cationization of silicone oil, and emulsified and dispersed by reacting tertiary amine with dimethyl sulfate (DMS) as an auxiliary emulsifier. In addition to improving the emulsification stability and mechanical stability of silicone oil by providing antistatic properties at the same time, and also to reduce process loss and defects caused by poor peeling, as well as to increase releasability Due to the use of the dimethylsilicone emulsion being treated, it is possible to simultaneously solve the disadvantage that it is difficult to give a stable resistance value to the sheet. In addition, the PET sheet treated with a cationic antistatic agent having a release property of the present invention has a 10 8 ~ 10 9 Ω degree enough to satisfy 10 11 Ω before and after molding, the resistance value is a general reference value, and without addition of other release agents As it can be processed in one liquid form, it can give process efficiency at the same time. Therefore, the quaternary ammonium salt-type silicone product gives the delamination phenomenon at PET sheet processing factory smoothly to improve the process efficiency and at the same time excellent antistatic function. It can be usefully applied to PET sheet products that give differentiated functions, such as wrapping paper. |
