Description
Известен способ получени лаковых смол на основе отходов полиэтилентерефталата путем их алкоголиза глицерином при высокой температуре в присутствии катализатора.A method is known for producing lacquer resins based on polyethylene terephthalate waste by alcoholising them with glycerol at a high temperature in the presence of a catalyst.
Дл упрощени технологического процесса и повышени качества смол предлагаетс полученные олнгомеры конденсировать с двухосновными кислотами при нагревании. Процесс алкоголиза провод т при 240°С и процесс поликонденсации- при 200-220°С.To simplify the process and improve the quality of the resins, it is proposed to condense the obtained olgomers with dibasic acids when heated. The process of alcoholysis is carried out at 240 ° C and the process of polycondensation at 200-220 ° C.
Пример. В реактор, снабженный мешалкой с затвором, термометром и обратным холодильником , загружают глицерин и нолиэтилентерефталат (отходы) в мол рном соотношении 0,5 : 0,7 (в случае полиэтилентерефталата расчет производитс по повтор юшемус звену, молекул рный вес 192), поднимают температуру до 240°С, выдерлсивают до посто нной температуры разм гчени по кольцу и шару (около 40 мин) и загружают 0,5 моль адининовой кислоты (себециновой, изофталевой ). Поликонденсацию олпгомеров провод т при 2QO-220°С в течение 3-4 час. Полученную смолу с кислотным числом 5-10л1г КОН/г,Example. Glycerin and polyethylene terephthalate (waste) in a molar ratio of 0.5: 0.7 are loaded into a reactor equipped with a stirrer with a shutter, a thermometer, and a reflux condenser (in the case of polyethylene terephthalate, the calculation is repeated using a Yushomus link, molecular weight 192), the temperature is raised up to 240 ° C; pull out to a constant softening temperature around the ring and the ball (about 40 minutes) and load 0.5 mol of adinic acid (self-citric, isophthalic). Polycondensation of olpgomers is carried out at 2QO-220 ° C for 3-4 hours. The obtained resin with an acid number of 5-10l1g KOH / g,
гидроксильным числом 5-6% и температурой разм гчени по кольцу и шару 65-85°С раствор ют в смеси трикрезола с сольвентом (1 : 1), добавл ют 1,5-3,0% эфира титановой кислоты.hydroxyl number of 5-6% and softening temperature around the ring and the ball 65-85 ° C are dissolved in a mixture of tricresol and solvent (1: 1), 1.5-3.0% of titanium ester is added.
Смолу используют дл эмалировани медных проводов круглого и пр моугольного сечени . Покрыти хорошо нанос тс , обладают высокой адгезией, термостойкостью и хорошей стойкостью к толуолу.The resin is used to enamel copper wires of round and rectangular cross section. The coatings are well applied, have high adhesion, heat resistance and good toluene resistance.
