Изобретение касаетс создани изделий из полистирола.The invention relates to the creation of products from polystyrene.
Известны композиции на основе полистирола И1 полимерного или сажевого наполнителей. Однако издели , полученные на основе этих композиций, короб тс при повышенных температурах , а пленки имеют большую усадку.Known compositions based on polystyrene I1 polymeric or carbon black fillers. However, the products obtained from these compositions are boxed at elevated temperatures, and the films have a greater shrinkage.
Цель изобретени - снизить усадку пленок и повысить формоустойчивость изделий на основе полистирола при повышенных температурах .The purpose of the invention is to reduce the shrinkage of films and improve the dimensional stability of products based on polystyrene at elevated temperatures.
Это обеспечиваетс введением в полистирол порошка полиамида 68 с размером частиц менее 40 мк И1 сажи ДГ-100 (газовой канальной диффузионной с удельной геометрической поверхностью около 100 ).This is ensured by the introduction of polyamide 68 powder with a particle size of less than 40 microns I1 of carbon black DG-100 (gas channel diffusion with a specific geometric surface of about 100) into polystyrene.
Предлагаема композици характеризуетс значительно меньшими внутренними напр жени ми , отсутствием усадки выше температуры стекловани (100°С и короблени прИ этих температурах, а также повышенной величиной прочности.The proposed composition is characterized by significantly lower internal stresses, the absence of shrinkage above the glass transition temperature (100 ° C and warping at these temperatures, as well as increased strength.
Пример. Композицию на основе полистирола эмульсионной полимеризации марки А (ГОСТ 9440-60), содержащую 0,5% вес. порошка из отходов вторичной переработки полиамида 68 с размером частиц менее 40 мкм и 0,05% вес. сажи ДГ-100, получают смешиванием в течение одного часа на шаровой мельнице . Из этой композиции отпрессовывают при температуре 180°С и удельном давленииExample. Composition based on polystyrene emulsion polymerization grade A (GOST 9440-60), containing 0.5% weight. powder from waste recycling polyamide 68 with a particle size less than 40 microns and 0.05% weight. soot DG-100, obtained by mixing for one hour in a ball mill. From this composition, it is pressed at a temperature of 180 ° C and a specific pressure

из полистирола № композиций на его основе, а также величины коэффициентов термического линейного расширени представлены в таблице . Предмет изобретени Композици на основе полистирола и полиамидного наполнител , отличающа с тем, что, с целью снижени усадки и повышени 5 формоустойчивости изделий из полистирола при повышенных температурах, порошок полиамида 68 с размером частиц менее 40 мк в количестве 0,05-0,8 вес. % введен в композицию совместно с 0,01-0,1 вес. % канальной, диффузионной газовой сажи с удельной геометрической поверхностью около 100 ( ДГ-100).polystyrene No. of compositions based on it, as well as the values of thermal linear expansion coefficients are presented in the table. The subject of the invention is a composition based on polystyrene and polyamide filler, characterized in that, in order to reduce shrinkage and increase 5 dimensional stability of polystyrene products at elevated temperatures, polyamide 68 powder with a particle size less than 40 microns in an amount of 0.05-0.8 weight . % introduced into the composition together with 0.01-0.1 weight. % channel diffusion carbon black with a specific geometric surface of about 100 (DG-100).
