Description
Изобретение относитс к составу композиции па основе полиметилметакрилата, примен емой , например, дл получени литьевых ударопрочных материалов, а также изделий, получаемых методом экструзии, используемых дл производства морозостойких топливопроводов , товаров широкого потреблени и крупногабаритных изделий светотехнического назначени .The invention relates to a composition based on polymethyl methacrylate based on, for example, for the production of injection-molded impact-resistant materials, as well as extrusion products used for the production of cold-resistant fuel lines, consumer goods and large-sized lighting products.
Известна композици , включающа полиметилметакрилат (ПММА) и сополимер метилметакрилата (ММА), бутадиена (БД) и стирола (СТ).A known composition comprising polymethyl methacrylate (PMMA) and a copolymer of methyl methacrylate (MMA), butadiene (BD) and styrene (CT).
Недостатком известной композиции вл етс низка ударопрочность.A disadvantage of the known composition is low impact resistance.
Цель изобретени состоит в повышении ударопрочности композиции при сохранении низкой температуры текучести. Поставленна цель достигаетс тем, что в состав композиции дополнительно ввод т сополимер метилметакрилата с бутилакрилатом (БА) с содерл анием звеньев бутила-крилата 30-50 вес. %.The purpose of the invention is to increase the impact strength of the composition while maintaining a low pour point. This goal is achieved by additionally adding methyl methacrylate-butyl acrylate (BA) copolymer with the content of butyl-crylate units of 30-50 wt. %
Компоненты композиции берут в следующем соотношении, вес. ч.:The components of the composition taken in the following ratio, wt. including:
Полиметилметакрилат100Polymethyl methacrylate100
Сополимер метилметакрилата , бутила крилата, стирол л Б---О Сополимер метилметакрилата с бутилакрилатом1 -15.Methyl methacrylate copolymer, butyl crylate, styrene l B --- O Methyl methacrylate copolymer with butyl acrylate1-15.
В качестве сополимера метилме:акри ата, бутадиена и стирола используют сополимер,As a copolymer of methylme: acry ata, butadiene and styrene, a copolymer is used,
