Изобретение относитс  к стабилизации поливинилхлорида (ПВХ) эноксисоединени ми (ЭС).This invention relates to the stabilization of polyvinyl chloride (PVC) by enoxo compounds (ES).

Известна йоливинилхлоридна  композици , содержаща  синергическую смесь эпоксидной диа-новой смолы (ЭД-5) и металлсодержащего стабилизатора. Однако термостабильность такой композиции недостаточно высока .A yvivinyl chloride composition is known, containing a synergistic mixture of epoxy diamine resin (ED-5) and a metal-containing stabilizer. However, the thermal stability of such a composition is not high enough.

Целью изобретени   вл етс  значительное увеличение термостабильности и морозостойкости , получение неокрашенных изделий, улучщение физико-механических свойств искусственной кожи на ИВХ-основе, расщирение ассортимента эпоксистабилизаторов. Дл  достижени  этой цели в композицию на основе поливинилхлорида (ПВХ) в качестве эпоксистабилизатора введен эпоксипропилфталимид (ЭПФ) в синергических смес х с металлсодержащими соединени ми в количестве 1- 5 вес. ч. В композицию дополнительно могут быть введены различные целевые добавки. В частности, дл  получени  искусственной кожи на ПВХ-основе в нее должен быть введен пластификатор .The aim of the invention is a significant increase in thermal stability and frost resistance, obtaining unpainted products, improving the physico-mechanical properties of artificial leather on IVH basis, expanding the range of epoxy stabilizers. To achieve this goal, epoxypropyl phthalimide (EPP) is introduced into the composition based on polyvinyl chloride (PVC) as an epoxy stabilizer in synergistic mixtures with metal-containing compounds in an amount of 1 to 5 wt. including the composition can additionally be introduced various target additives. In particular, in order to obtain an artificial leather on a PVC base, a plasticizer must be introduced into it.

Пример. Пленки, примен емые дл  получени  искусственной кожи, получают следующим образом. Стабилизаторы затирают с пластификатором и ввод т смесь в ПВХ-смолу,Example. The films used to make artificial leather are prepared as follows. The stabilizers are rubbed with a plasticizer and the mixture is introduced into the PVC resin,

Пленкообразование осуществл ют на вальцах при 135-145°С, затем пленки формуют на гидропрессе при 145±5°С в течение 10 мин с последующим охлаждением. Оптимальна  дозировка композиции: 5 вес. ч. ЭПФ и 1 -Film formation is carried out on rollers at 135-145 ° C, then the films are molded in a hydraulic press at 145 ± 5 ° C for 10 minutes, followed by cooling. The optimal dosage of the composition: 5 wt. h. epp and 1 -

2 вес. ч. стеарата кальци , 50 вес. ч. пластификатора , например дибутилфталата, на 100 вес. ч. ПВХ марки С-70.2 wt. including calcium stearate, 50 wt. including plasticizer, for example dibutyl phthalate, per 100 weight. h. PVC brand C-70.

Полученные пленки испытывают на прочность как до старени , так и после облучени The films obtained are tested for strength both before aging and after irradiation.

лампой ПРК-2, определ ют термостабильность и морозостойкость.lamp PPK-2, determine thermal stability and frost resistance.

Результаты испытаний представлены в таблице в сравнении с аналогичными показател ми при испытании ПВХ-пленок, содержащих промышленный стабилизатор ЭД-5.The test results are presented in the table in comparison with similar indicators when testing PVC films containing the industrial stabilizer ED-5.

Как видно из таблицы, предел прочности при раст жении, морозостойкость, а особенно термостабильность значительно выше в случае применени  ЭПФ.As can be seen from the table, the tensile strength, frost resistance, and especially thermal stability are much higher in the case of the use of EPP.

Предмет изобретени  Subject invention

Поливинилхлоридна  композици , содержаща  синергическую смесь эпокси- и металлсодержащих стабилизаторов, например стеарата кальци , отличающа с  тем, что, с целью увеличени  термостабильности и морозостойкости , получени  неокрашенных изделийPolyvinyl chloride composition containing a synergistic mixture of epoxy and metal containing stabilizers, e.g. calcium stearate, characterized in that, in order to increase thermal stability and frost resistance, to obtain unpainted products

и улучшени  физико-механических свойств искусственной кожи на основе этой композиции, в качестве эпоксистабилизатора применен эпоксипропилфталимид, и компоненты вз ты в следующем соотнощении (в вес. ч.):and improving the physicomechanical properties of artificial leather based on this composition, epoxypropylphthalimide was used as an epoxy stabilizer, and the components were taken in the following ratio (in weight parts):
