Description
В технике приготовлени масл но-смол ных лаков, олиф и эмалевых красок имеет значение процесс полимеризации масел, определ ющий мал рпо-технические качества продукта.In the technique of preparing oil-resin varnishes, linseed oil, and enamel paints, the process of polymerization of oils is important, which determines the small-technical qualities of the product.
В промышленности полимеризацию масел ведут обычно путем термической обработки их при температуре 280-290° в присутствии катализаторов , в качестве которых примен ют окислы металлов и органические перекиси. Однако этот способ полимеризации масел требует много времени, например дл нодсолпечного масла около 60-70 часов.In industry, the polymerization of oils is usually carried out by heat treatment of them at a temperature of 280-290 ° in the presence of catalysts, in which metal oxides and organic peroxides are used. However, this method of polymerizing oils takes a long time, for example, for nodsolpechnogo oil about 60-70 hours.
Известен ускоренный способ полимеризации масел, также основанный на их термической обработке, но при температуре до 300 и в присутствии 5-10% непредельных органических соединений алифатического и ароматического - р да, склонных к полимеризации, как-то: изопрена, ундециленовой и акрилоной кислоты, стирола, дивинилацетиле1 а , полимеров, соответствуюП1 ,их им галоидопроизводных и т. п. При этом способе рекомендуетс нести нроцесс полимеризации в автоклаве.There is an accelerated method for the polymerization of oils, also based on their heat treatment, but at temperatures up to 300 and in the presence of 5-10% unsaturated organic compounds of aliphatic and aromatic - a number that are prone to polymerization, such as: isoprene, undecylenic and acrylon acid, styrene, divinylacetyl1 a, polymers, corresponding to P1, their halogen derivatives, etc. In this method, it is recommended to carry out the polymerization process in an autoclave.
Описываемый способ отличаетс от известных тем, что к термически обрабатываемому маслу добавл ют в качестве катализатора полистирол в количестве 0,2-1,5% , упроща этим технологический процесс полимеризации. Введепие полистирола в масло может проводитьс как в начале процесса, так и после некоторой предварительной полимеризации масла. При этом полимеризаци масла протекает быстрее в 2-3 раза с образованием более светлых продуктов в сравнении с продуктами, получаемыми при применении обычных катализаторов- глета, пиролюзита и др.The described method differs from those known in that polystyrene in an amount of 0.2-1.5% is added to the heat-treated oil as a catalyst, thereby simplifying the polymerization process. The introduction of polystyrene into the oil can be carried out both at the beginning of the process and after some preliminary polymerization of the oil. At the same time, the polymerisation of the oil proceeds by 2-3 times faster with the formation of brighter products in comparison with the products obtained using conventional catalysts — flat, pyrolusite, etc.
Химизм процесса состоит в постепенном нарушении полистиролом своей нормальной структуры, с образованием активных молекул моно- и димеров стирола и во взаимодействии этих молекул с молекулами масла. Полистирол, как известно , нелетучее высокомолекул рное органическое соединение. Поэтому процесс полимеризации масел но предлагаемому способу может вестись в любой открытой, установленной на лакокрасочных заводах аппаратуре.The chemistry of the process consists in the gradual disruption by polystyrene of its normal structure, with the formation of active molecules of mono- and dimers of styrene, and in the interaction of these molecules with the molecules of oil. Polystyrene is known to be a non-volatile, high molecular weight organic compound. Therefore, the process of polymerization of oils but the proposed method can be carried out in any open apparatus installed at paint and varnish factories.

Температ фу поднимают до 280-290 и провод т полимеризацию до ползчепи в зкости масла 40-45° по воронке МИИЛКа № 7 при 20°.An example of the polymerization of sunflower oil .. 1000 in. hours of oil is heated to a temperature of 260 ° and introduced into it 8 c. h, polystyrene. The temperature of fu is raised to 280-290 and polymerization is carried out until the oil viscosity creep is 40-45 ° using a MIILK No. 7 funnel at 20 °.
Предмет изобретени Способ полимеризации масел путем термической обработки их при температуре 280-290° в присутствии катализатора, отличающийс тем, что, с целью упрощени технологического процесса, в качестве катализатора примен ют полистирол , который добавл ют в количестве от 0,2 до 1,5% в начале процесса или после частичной полимеризации масла.The subject of the invention is a method of polymerizing oils by heat treating them at a temperature of 280-290 ° in the presence of a catalyst, characterized in that, in order to simplify the process, polystyrene is used as a catalyst, which is added in an amount of from 0.2 to 1.5 % at the beginning of the process or after partial polymerization of the oil.
