Description
Изобретение относитс к композици м дл получени пенополиогирольных изделий, наход щих широное применение в различн1 х: отасл х промышленности.This invention relates to compositions for the preparation of polyurethane foam articles that are widely used in various industries: industries.
Известна композици дл получени пенополистирольннх изделий, состо ща из вспенивающегос полистирола , лимонной кислоты и двууглекислого натри ,A known composition for the preparation of polystyrene foam products consisting of expandable polystyrene, citric acid and sodium bicarbonate,
Пенополистирольные издели получают из этой композиции методом лить под давлением. Polystyrene products are obtained from this composition by injection molding.
Недостатком этой композиции вл етс то, что ее трудно перерабатывать в качественные издели м,9тодом экструзии, а также и то, что Пенополистирольные издели на ее основе горючи. Кроме того, поскольку указанную композицию перерабатывают в Пенополистирольные издели литьем под давлением, то получаемые издели имеют большую плотность и неавномерное распределение нлохносH по сечению издели . ,The disadvantage of this composition is that it is difficult to process it into high-quality products, the method of extrusion, as well as the fact that Polystyrene foam products based on it are combustible. In addition, since the above composition is processed by injection molding into polystyrene foam products, the resulting products have a greater density and uneven distribution of negative across the product section. ,
Целью изобретени вл етс улучшение переработки композиции на основе всепенивающегос полистирола методом экструзии и получени на ее основе огнестойких изделий .The aim of the invention is to improve the processing of the composition based on the all-absorbing polystyrene by extrusion and on the basis of its fire-resistant products.
Эта цель достигаетс тем, что в композицию, состо щую из вспенивающегос полистироле, лимонной 0 кислоты и двууглекислого натри , введен тетрабромпараксилол при следующем соотношении компонентов, вес.ч.:This goal is achieved in that tetrabromparaxylene is introduced into the composition consisting of expandable polystyrene, citric acid and sodium bicarbonate in the following ratio of components, parts by weight:
Вспенивающийс полистирол 1СЮ 5 Лимонна кислота 0,3-2Expandable polystyrene 1СЮ 5 Citric acid 0.3-2
Двууглекислый натрий 0,2.2Sodium bicarbonate 0.2.2
Тетрабромпараксилол 1,0-10.Tetrabromoparaxylene 1.0-10.
На основе композиции по изобретению методом экструзии получают Пенополистирольные издели с равномерным распределением плотности и высокой огнестойкостью, причем огнестойкость изделий выше огнестойкости изделий, полученных на основе композиций, в которых используетс вспенивающийс полистирол, соBased on the composition of the invention, extruded polystyrene products are obtained by extrusion with a uniform density distribution and high fire resistance, and the fire resistance of the products is higher than the fire resistance of the products obtained on the basis of compositions that use expanding polystyrene with
