Description
Синтетические высокомолекул рные каучуки, обладающие наиболее высокими физико-механическими показател ми , полученные с помощью эмульсионной полимеризации, без применени регул тора, вл ютс обычло труднообрабатываемыми.Synthetic high-molecular rubbers with the highest physicomechanical indicators, obtained using emulsion polymerization, without the use of a regulator, are usually difficult to process.
Дл улучшени обрабатываемости таких каучуков в латекс.ы их ввод т различного -рода м гчители (главным образом нефтепродукты) в виде йодных эмульсий, в присутствие эмульгаторов.To improve the workability of such rubbers, latexes are introduced into them of various types of emollients (mainly petroleum products) in the form of iodine emulsions, in the presence of emulsifiers.
При этом последующа коагул и,и латекса производитс обычным способом.The subsequent coagulum and the latex is produced in the usual way.
Методы введени м гчителей раз 1ообразны .The methods of the introduction of the softener are 1 times.
Предлагаетс способ получени дивинилстирольных и дивинилмети.тсткрольных масл ных каучуков путем смещени водной эмульсии масла с латексом перед коагул л .ией.A method for the preparation of divinyl styrene and divinyl methylene chloride rubber rubbers is proposed by displacing the aqueous emulsion of the oil with the latex before coagulation.
Улучшение свойств каучука достигаетс тем, что в качестве пластификатора-наполнител вместо известHbix масел примен ют спецкально подобранное нефт ное масло авгол-18 , хорошо совмещающеес с каучуком. Дл получени стабильной масл ной эмульсии, не расслаивающейс при смешении с латексом, гlpIiмeн ют стеарат триэтаноламина вместо известных слеата натри , стеарата кали и других.Improvement of rubber properties is achieved by using special high-grade oil AUGOL-18, which combines well with rubber, instead of known Hbix oils as a plasticizer-filler. To obtain a stable oil emulsion that does not delaminate when mixed with a latex, tri-ethanolamine stearate, instead of the known sodium sulfate, potassium stearate, and others, is used.
При этом cTeapiiHOHaH кислота раствор етс в мас.те, затем Njacca (JXлaждaeтc и омыл етс 2огным водным раствором триэтаноламина.At the same time, cTeapiiHOHaH acid dissolves in wt.%, Then Njacca (JH is saturated and washed with 2N aqueous triethanolamine solution.
Такой прием эму.1ьгировапи масла позвол ет по.чуч1ггь мелкод1-;сперсную эмульсин:) в мешалках с небольHiHM числом оборотов (50-150 об/мин.) без применени специальных аппаратов-эмульгаторов.Such a method of emu.1ngirovapi oil allows one to mix fine 1-; spurs emulsin :) in mixers with a low HiMH speed (50-150 rpm) without the use of special emulsifying apparatuses.
В состав эмульсии входит масло, стеаринова кислота, триэтано.тамин и вода.The composition of the emulsion includes oil, stearic acid, triethano.tamin and water.
слови смещени эмульсии масла с латексо.м следующие. Латекс охлаждаетс до 25-35, так как при белее высоких температурах эмульси масла разрушаетс . Само смешение эмульсии масла и латекса можно производить дво ко: или смешивают заранее отмеренные количества латекса и эмульсии в емкости, что с цсльн, облегчени сварш cirra из OTiibHbx ггемснтов, ош постоит из пли™ , р ва.ниых на коп не-иолнокруж,ных .ыступов и ограничии ш д. фик осрова и положени неполных колец и щ. мых отрсзшв на врем CB.piUi.According to the displacement of the oil emulsion with latex, the following. The latex is cooled to 25-35, since at higher temperatures, the emulsion of the oil is destroyed. The mixture of oil and latex emulsion itself can be doubled: or pre-measured quantities of latex and emulsion are mixed in a container, which can be done with the aid of OTiibHbx heaters OTiibHbx gemsets, Osh will be built from Pl ™, Rv. protrusions and restrictions w. fic ture and the position of incomplete rings and shch. we have received at the time of CB.piUi.
