Abstract
Description
Изобретение относится к промышленности пластмасс и касается разработки термопластичной композиции на основе полипропилена для получения изделий с улучшенными оптическими и физико-механическими показателями. The invention relates to the plastics industry and for the development of a thermoplastic composition based on polypropylene to obtain products with improved optical and physico-mechanical properties.
Известны технологические приемы переработки полипропиленовых композиций, к которым в первую очередь относят температуры расплава, скорости охлаждения, ведение различных структурообразователей и ПАВ, способствующих получению изделий с необходимыми свойствами (Иванюков Д.В., Фридман М.Л. Полипропилен. - М.: Химия, 1974, с. 67-69, 138-140). Known technological methods for processing polypropylene compositions, which primarily include melt temperatures, cooling rates, the maintenance of various structure-forming agents and surfactants that contribute to the production of products with the necessary properties (Ivanyukov D.V., Fridman M.L. Polypropylene. - M.: Chemistry , 1974, p. 67-69, 138-140).
Наиболее близким техническим решением является полипропиленовая композиция, включающая стабилизатор и технологическую добавку, обеспечивающих оптимальные реологические характеристики и физико-механические показатели изделиям на ее основе (RU 2028330 С1, 05.07.1991). The closest technical solution is a polypropylene composition, including a stabilizer and a technological additive, providing optimal rheological characteristics and physical and mechanical properties of products based on it (RU 2028330 C1, 05.07.1991).
Однако данная композиция не обеспечивает изделиям улучшения оптических характеристик. However, this composition does not provide products with improved optical characteristics.
Поставленная техническая задача решается тем, что композиция на основе полипропилена, включающая стабилизатор, представляющий собой "Ирганокс 1010" - эфир 3,5-ди-трет-бутил-4-гидроксифенилпропионовой кислоты и пентаэритрита, и технологическую добавку, в качестве последней содержит фосфит на основе 2,2'-тиобис(4-метилфенола) и диметилдибензолиденсорбитол при следующем соотношении компонентов композиции в маc.ч.:
Полипропилен - 96,7-99,7
Пентаэритритовый эфир 3,5-ди-третбутил-4 окси-фенилпропионовой кислоты - 0,1-0,2
Фосфит - 0,05-0
Диметилдибензолиденсорбитол - 0,15-2,5
По изобретению используют:
- "Ирганокс 1010" торговая марка стабилизатора ПП (Швейцария), представляющего собой пентаэритритовый эфир 3,5-ди-трет-бутил-4-окси-фенилпропионовой кислоты (см. Стабилизация пленочных материалов и искусственных кож. - М.: ЦНИИТЭИлегпром, 1974, с. 139);
- фосфит на основе 2,2'-тиобис(4 метилфенола), представляет собой полифункциональный антиоксидант, торговая марка "ТБФ-Ф", кристалический порошок, Т. пл. = 100oC , М.м. = 520 (см. Стабилизация пленочных материалов и искусственных кож. - М.: ЦНИИТЭИлегпром, 1974, с. 81, 83, 87-88);
диметилдибензолиденсорбитол - кристаллический порошок, Т.пл. = 100oС, М. м. = 365.The stated technical problem is solved in that the composition is based on polypropylene, including a stabilizer, which is Irganox 1010 - an ether of 3,5-di-tert-butyl-4-hydroxyphenylpropionic acid and pentaerythritol, and the technological additive contains phosphite as based on 2,2'-thiobis (4-methylphenol) and dimethyldibenzene-sordensol in the following ratio of components of the composition in wt.h .:
Polypropylene - 96.7-99.7
3,5-di-tert-butyl-4 hydroxy-phenylpropionic acid pentaerythritol ester - 0.1-0.2
Phosphite - 0.05-0
Dimethyldibenzene-sensorbitol - 0.15-2.5
According to the invention use:
- "Irganox 1010" trademark stabilizer PP (Switzerland), which is a pentaerythritol ester of 3,5-di-tert-butyl-4-hydroxy-phenylpropionic acid (see. Stabilization of film materials and artificial leather. - M .: TSNIITEIlegprom, 1974 p. 139);
- phosphite based on 2,2'-thiobis (4 methylphenol), is a multifunctional antioxidant, TBF-F trademark, crystalline powder, T. pl. = 100 o C, M.m. = 520 (see. Stabilization of film materials and artificial leather. - M.: TSNIITEIlegprom, 1974, p. 81, 83, 87-88);
dimethyldibenzene-densensorbitol - crystalline powder, mp = 100 o C, M. m. = 365.
Изобретение иллюстрируют примеры. The invention is illustrated by examples.
Пример 1
Полипропилен "Каплей" (ТУ2211-015-00203521-95) смешивают с ингредиентами композиции при комнатной температуре с последующей переработкой смеси через щелевую головку экструдера марки "ОМУ" в лист толщиной 1,5 мм и шириной (585±1) мм.Example 1
Polypropylene "Drop" (TU2211-015-00203521-95) is mixed with the ingredients of the composition at room temperature, followed by processing the mixture through a slit head of an "OMU" brand extruder into a sheet 1.5 mm thick and 585 ± 1) mm wide.
Режимы формования представлены в табл. А. Forming modes are presented in table. A.
Расплав полимерной композиции из щелевой головки подается на 3-валковый каландр, где калибруется необходимая толщина. После прохождения 3-го вала - охлаждающего, лист в свободном состоянии подвергается вытяжке со скоростью 3,7 м/мин и после полного охлаждения подается на термовакуумное формование. The molten polymer composition from the slit head is fed to a 3-roll calender, where the required thickness is calibrated. After passing through the 3rd shaft - cooling, the sheet in the free state is subjected to extraction at a speed of 3.7 m / min and after complete cooling is fed to thermal vacuum molding.
Формование изделий из листа осуществляют на термоформовочной машине "ОМУ Р25Я10" со скоростью 16 циклов в минуту, при средней температуре 11-зонного верхнего нагрева формующего гнезда 439,5oС и нижнего 10-зонного - 389oС. Толщина готового изделия 0,2 мм. Свойства готового изделия представлены в табл. 2.Sheet products are formed on the OMU R25Y10 thermoforming machine at a speed of 16 cycles per minute, at an average temperature of the 11-zone top heating of the forming socket 439.5 o С and the lower 10-zone - 389 o С. Thickness of the finished product 0.2 mm Properties of the finished product are presented in table. 2.
Примеры 2-5
Аналогично примеру 1 готовят композиции, составы которых указаны в табл. 1 и на экструдере готовят листы толщиной 1,5 мм, из которых на термоформовочной машине формуют изделия толщиной 0,20 мм. Свойства изделий представлены в табл. 2.Examples 2-5
Analogously to example 1 prepare compositions, the compositions of which are shown in table. 1 and sheets with a thickness of 1.5 mm are prepared on an extruder, of which products with a thickness of 0.20 mm are formed on a thermoforming machine. The properties of the products are presented in table. 2.
Анализ данных, приведенных в табл. 2, свидетельствуют о том, что использование в качестве технологической добавки смеси фосфита на основе 2,2'-тиобис(4-метилфенола) и диметилдибензолиденсорбитола оказывает существенное влияние на изменение оптических и физико-механических показателей изделий из предложенной композиции. Analysis of the data given in table. 2, indicate that the use of a mixture of phosphite based on 2,2'-thiobis (4-methylphenol) and dimethyldibenzene-sensorbitol as a technological additive has a significant effect on the change in the optical and physicomechanical parameters of products from the proposed composition.
