Description
СПОСОБ СТАБИЛИЗАЦИИ ПОЛИВИНИЛХЛОРИДАMETHOD OF STABILIZATION OF POLYVINYL CHLORIDE
Изобретение относитс к способу стабилизации поливинилхлорида (ПВХ).This invention relates to a method for stabilizing polyvinyl chloride (PVC).
Известен способ стабилизации ПВХ с применением в качестве стабилизатора стеарата или силиката свинца.There is a method of stabilizing PVC using as a stabilizer stearate or lead silicate.
Предлагаемый способ заключаетс в том, что в качестве стабилизатора дл ПВХ примен ют упом нутые соли свинца вместе с полиоксибензиловыми эфирами общей формулыThe proposed method consists in using the lead salts together with the polyoxybenzyl esters of the general formula as a stabilizer for PVC.

Добавка в ПВХ 1 вес. ч. композиции стабилизатора «ФФ на 100 вес. ч. ПВХ повыщает термостабильность пластиката более чем в 3 раза. Стабилизатор хорошо совмещаетс с ПВХ и раствор етс в пластификаторе. Температура плавлени стабилизатора «ФФ 100-110°С.Additive in PVC 1 wt. including the composition of the stabilizer "FF per 100 weight. h. PVC increases the thermal stability of plastic compound more than 3 times. The stabilizer blends well with PVC and dissolves in the plasticizer. The melting point of the stabilizer FF is 100-110 ° C.

Вз тые компоненты смешивают в смесител х в течение 1 час при температуре 75- 80°С, затем композицию на вальцах перерабатывают в пластикат при температуре 160- 165°С в течение 15 мин.The taken components are mixed in mixers for 1 hour at a temperature of 75-80 ° C, then the composition on rollers is processed into plastic at a temperature of 160-165 ° C for 15 minutes.
Таблица 1Table 1
Таблица 2table 2
В табл. 2 приведены сравнительные данные по поливипилхлоридпым пластикатам, стабилпзированным двухосновным стеаратом свинца , смесью двухосновного стеарата свинца и продукта «ФФ, а также одним продуктом «фф.In tab. 2 shows comparative data on polyvinyl chloride plastics, stabilized dibasic lead stearate, a mixture of dibasic lead stearate and the product “FF, as well as one product” FF.
Аналогичные результаты получены при применении силиката свинца и смеси его с «ФФ.Similar results were obtained when lead silicate was used and it was mixed with FF.
Как видно из таблицы, один продукт «ФФ не про вл ет себ как стабилизатор. Смесь же его со свинцовыми стабилизаторами значительно повышает показатели по термостабильности и светотермостойкости пластиката .As can be seen from the table, a single FF product does not appear as a stabilizer. A mixture of it with lead stabilizers significantly improves the thermal stability and light-thermal resistance of plastic.
Предмет изобретени Subject invention
Способ стабилизации поливинилхлорида путем введени в пего силиката свинца или стеарата свипца, отличающийс тем, что, с целью повышени термостабильности и светотермостойкости поливинилхлорида, силикат свинца или стеарат свинца примен ют совместно с полиоксибензиловыми эфирами в соотпошепии соответственно .A method of stabilizing polyvinyl chloride by introducing lead silicate or swipe stearate into it, characterized in that, in order to increase the thermal stability and light-thermal resistance of polyvinyl chloride, lead silicate or lead stearate is used in conjunction with polyoxybenzyl esters in accordance with the corresponding schedule.
