Description
Получение морозостойких резин имеет весьма актуальное значение дл р да отраслей народного хоз йства , примен ющих различные резиновые издели .The production of frost-resistant rubbers is of great importance for a number of branches of the national economy that use various rubber products.
Еще большее значение имеет вопрос получени бензомаслостойкой резины , сопротивл ющейс действию низких температур (рукава, прокладки и т. п.).Of even greater importance is the issue of obtaining a gas-oil resistant rubber that resists the effects of low temperatures (sleeves, gaskets, etc.).
Дл получени бензомаслостойких изделий в насто щее врем примен етс севанит, резинит и совместные их комбинации, а также комбинации их с синтетическим натрий-бутадиеновым каучуком или с натуральным каучуком. Однако применение таких вулканизаторов при низких температурах ограничено вследствие плохой сопротивл емости холоду даже пор дка минус 25-30° С. Дл повышени морозостойкости указанных каучуков, в них ввод тс различные антифризы (дибутилфталат).Sevanite, rubber and their combined combinations, as well as their combinations with synthetic sodium-butadiene rubber or with natural rubber, are currently used to obtain gas-oil resistant products. However, the use of such vulcanizers at low temperatures is limited due to the poor resistance to cold, even on the order of minus 25-30 ° C. To increase the frost resistance of these rubbers, various antifreezes (dibutyl phthalate) are introduced into them.
Проведенные работы показали, что дл повышени морозостойкости изделий из бензомаслостойких смесей нет необходимости вводить в смеси те или иные дорогосто щие анти20The work performed has shown that in order to increase the frost resistance of products from gas oil and oil resistant mixtures, it is not necessary to introduce some kind of expensive antir
фризы, так как по существу действие их, в смысле повышени морозостойкости изделий, сравнительно невелико и ограничено, вследствие вымывани антифризов соприкасающейс с ними во врем работы жидкостью .friezes, since essentially their action, in the sense of increasing the frost resistance of products, is relatively small and limited, due to the leaching of the antifreezes that are in contact with them during operation.
Предлагаемый способ повышени морозостойкости изделий из бензомаслостойких смесей заключаетс в предварительном набухании издели в течение различных промежутков времени в бензине, маслах и других продуктов с низкой температурой застывани в зависимости от назначени примен емых резиновых изделий.The proposed method of improving the frost resistance of products made from gas-oil resistant mixtures consists in pre-swelling the product for various periods of time in gasoline, oils and other products with a low pour point depending on the purpose of the rubber products used.
Применение способа на практике имеет р д преимуществ:The application of the method in practice has several advantages:
1.Обработанные по этому способу бензомаслостойкие издели способны выдерживать температуру до минус 50-60° С, при которой обычные издели с антифризами тер ют все признаки эластичности.1. Gasoline and oil resistant products treated by this method are able to withstand temperatures up to minus 50-60 ° С, at which ordinary products with antifreeze lose all signs of elasticity.
2.Дл изготовлени морозостойких бензомаслоупорных смесей не требуетс применени специальных дорогосто щих антифризов.2. For the manufacture of cold-resistant gas-oil-resistant mixtures, no special expensive antifreeze is required.
3.Соприкасающиес с такими из№ 72159- 2 дели ми материалы (бензин, маслоновых смесей с содержанием антии др.), не загр зн ютс , вследствиефризов или без таковых, о т л и ч а говымывани антифризов.щ и и с тем, что издели подвер„ гают предварительному набуханию в Предмет изобретени бензине, маслах и т. п. жидких проСпособ повышени морозостойкостидуктах, имеющих низкую темпераизделий из бензомаслостойких рези-туру застывани .3. Materials in contact with such materials No. 72159-2 (gasoline, oil mixtures with an anti-chemical content) are not polluted, due to or without a freeze, antifreeze and that the products undergo preliminary swelling in the subject of the invention of gasoline, oils, etc., liquid processes to increase the frost-resistance of the products that have a low tempera- ture of petrol-oil-resistant freezing rubber.
