Description

Известно применение -продуктов переработки нефти в качеотве растворителей при регенерации резииы -из синтетическогО каучука.It is known to use the products of oil refining as a solvent for the regeneration of rubber — from synthetic rubber.

Авторы изобретени  предлагают способ регенерации резины из синтетического каучука, состо щий в том, что в качестве растворител  примен ют перегон ющуюс  в пределах 100-250° фракцию смолы, получаемой при ароматлзации нефти или, так называемый, нефт ной сольвент.The inventors propose a method for regenerating synthetic rubber rubber, which consists in using a fraction of the resin distilled within the aromatization of oil or the so-called oil solvent as a solvent.

Последний представл ет собой остаток от разгонки легкого масла и состоит , глаВНым образом, из ароматических углеводородов. Нар ду с тем в «ем содержитс  около 20% непредельных соединений жирного р да. Соаш1вент  вл етс  отходом производства , не имеющим до насто щего времени рационального применеми , и получаетс  при пиролизе «ефти IB больших количествах, измер емых тыс чами тон .The latter is a residue from the distillation of a light oil and consists mainly of aromatic hydrocarbons. In addition, it contains about 20% unsaturated fatty compounds. Soventvent is a waste product that has not been used rationally up to now, and it is obtained by pyrolyzing ' ephti IB large quantities, measured in thousands of tons.

Технологический процесс регенерации резины из СК при помощи сольвента осуществл етс  следующим образом .The technological process of rubber regeneration from SC using the solvent is carried out as follows.

Измельченна  резина напре ваетс  в зак;рытом сосуде с 10 3-крат«ымThe ground rubber is directed in a zak; ditched vessel with 10 3-fold

количеством сальвента при 100-175в течение различного времени, в зависимости от рода и качества регенерируемой резины. Из полученного раствора удал ют затем растворитель одним из известных способов.the amount of salventa at 100-175 for various times, depending on the type and quality of the rubber being regenerated. The solvent is then removed from the resulting solution by one of the known methods.

Пример 1. Протекторную резину раствор ют при ISO в 7, 5-кратном количестве сольвента в течение 12 часов . Растворитель отгон ют острым napOjM. Полученный регенерат обладает следующими показател ми: пластичность ПО Карреру - 0,20; прочность на разрыв - 103 кг/см-; относительное удлинение - 430%; остаточное удлинение - 12%.Example 1. The tread rubber is dissolved at ISO 7, 5 times the amount of solvent within 12 hours. The solvent is distilled off with a sharp napOjM. The resulting regenerate has the following indicators: the plasticity of Carrera software is 0.20; tensile strength - 103 kg / cm; relative lengthening - 430%; residual elongation - 12%.

Пример 2. Протекторную резину раствор ют при 175° в услови х, описанных в примере 1. Полученный регенерат обладает следующими показател ми: пластичн1остъ по Карреру - 0,42; прочность на разрыв - 59 кг см-; относительное удлинение - 6257с; остаточное удлинение - 20%.Example 2. The tread rubber is dissolved at 175 ° under the conditions described in Example 1. The resulting regenerate has the following characteristics: Carrere plasticity - 0.42; tensile strength - 59 kg cm-; relative elongation - 6257c; residual elongation - 20%.

Регенераты, получаемые с помощью сольвента, обладают гладкой поверхностью , блест щим разрезом, превосхо«Д1но обрабатываютс  и не имеют непри тного запаха.The regenerates obtained with the help of the solvent have a smooth surface, a brilliant cut, which is excellently treated and does not have an unpleasant odor.
