Description

Изобретение относится к литью под давлением изделий из пластмасс, в частности к получению литьевых материалов на основе полиэтилентерефталата (ПЭТФ), а именно его от- 5 ходов, и может быть использовано в производстве товаров народного потребления.The invention relates to the injection molding of plastic products, in particular to the production of molding materials based on polyethylene terephthalate (PET), namely its waste, and can be used in the production of consumer goods.

Цель изобретения - улучшение перерабатывающей способности компози- 10’ дии при литье под давлением и повышение физико-механических показателей изделий.The purpose of the invention is to improve the processing capacity of the composition of the 10 'diya during injection molding and increase the physico-mechanical properties of the products.

В композиции используют поликарбонат дифлон (ПК) по ТУ 6-05-1668-79 15 и ударопрочный полистирол (УП) по ОСТ 6-05-406-80.The composition uses polycarbonate diflon (PC) according to TU 6-05-1668-79 15 and high impact polystyrene (UE) according to OST 6-05-406-80.

ПЭТФ известен как исходный материал для формования волокон и пленок, прочность которых достигается 20 при ориентации. При их производстве образуются отходы как ориентированных, так и не ориентированных (аморфных) материаловОба вида отходов смешивают и подвергают грануляции 25 с целью снижения их удельной поверхности и ограничения окислительных процессов при переработке.PET is known as a starting material for the formation of fibers and films, the strength of which is reached 20 during orientation. During their production, wastes of both oriented and not oriented (amorphous) materials are formed. Both types of waste are mixed and granulated 25 in order to reduce their specific surface and limit oxidative processes during processing.

По существенным техпроцессам грануляции пленочных и волокнистых зд !отходов получают вторичный ПЭТФ с низкой молекулярной массой по ТУ 6-19-150-80 (удельная вязкость 0,5%--ного раствора ПЭТФ в трикрезоле 0,1-0,25 с) .According to the significant technological processes of granulation film and fiber zd ! wastes receive secondary PET with low molecular weight according to Specifications 6-19-150-80 (specific viscosity of a 0.5% solution of PET in tricresol is 0.1-0.25 s).

Сравнительная характеристика некоторых физико-механических показателей первичного ПЭТФ и его отходов приведена в табл. 1.Comparative characteristics of some physico-mechanical parameters of primary PET and its waste are given in table. one.

Пример 1. Отходы ПЭТФ в количестве 980 г влажностью не более 0,01%, 10 г поликарбоната и 10 г ударопрочного полистирола перемешивают в барабане шаровой мельницы в течение 15 мин. Приготовленную композицию загружают в бункер литьевой машины и изготавливают изделия при следующих технологических параметрах литья:.Example 1. PET waste in the amount of 980 g with a moisture content of not more than 0.01%, 10 g of polycarbonate and 10 g of impact-resistant polystyrene are mixed in a drum of a ball mill for 15 minutes. The prepared composition is loaded into the hopper of the injection molding machine and the products are manufactured with the following technological casting parameters:

Пример 2. Отходы ПЭТФ в количестве 650 г, 220 г ударопрочного полистирола и 30 г поликарбоната, высушенные до влажности 0,01%, смешивают и перерабатывают так же, как и в примере 1.Example 2. Waste PET in the amount of 650 g, 220 g of impact polystyrene and 30 g of polycarbonate, dried to a moisture content of 0.01%, mixed and processed in the same way as in example 1.

Пример 3. Отходы ПЭТФ в количестве 450 г, 500 г ударопрочного полистирола и 50 г поликарбоната с влажностью 0,01% смешивают и перерабатывают при тех же параметрах, что и в примере 1.Example 3. Waste PET in the amount of 450 g, 500 g of impact polystyrene and 50 g of polycarbonate with a moisture content of 0.01% are mixed and processed with the same parameters as in example 1.
