Изобретение относитс к области получени пластичных смазок, обладающих новышенной электронроводностью, предназначенных дл электрических контактов, а также приборной техники, эксплуатирующейс в радиотехнической и электронной промышленности в услови х электрических нагрузок.The invention relates to the field of production of greases having a new electrical conductivity, intended for electrical contacts, as well as instrumentation used in the radio engineering and electronics industries under the conditions of electrical loads.
Известны пластичные электропровод щие смазки на основе олигонитрилсилоксановых жидкостей в качестве дисперсионной среды и загустителей - силикагел или солей металлов (I, II, III и IV групп периодической системы ), высших жирных кислот с добавлением диснергатора и присадок. Однако эти смазки не всегда удовлетвор ют требовани м, предъ вл емым к смазкам дл электрических контактов по качеству контактировани , например , контактов селекторов телевизионных каналов, что снижает надежность работы апнар-атуры .Plastic conductive lubricants based on oligonitrile siloxane fluids are known as a dispersion medium and thickeners — silica gel or metal salts (I, II, III, and IV groups of the periodic system), higher fatty acids with the addition of disnergator and additives. However, these lubricants do not always satisfy the requirements imposed on lubricants for electrical contacts in terms of the quality of contact, for example, contacts of selectors of television channels, which reduces the reliability of the apnar-atura operation.
Цель изобретени - разработка рецептуры пластичной смазки дл электрических контактов , обладающей высоким качеством контактировани и низким электрическим сопротивлением ..The purpose of the invention is to develop a plastic lubricant formulation for electrical contacts with high contact quality and low electrical resistance.
. Дл этого ло предлагаемому способу ввод т в смазку дополнительный загуститель - -бентонит . Введение бинарного загустител нридает смазке улучшенные контактные свойства.. For this, the proposed method is introduced into the lubricant additional thickener - - bentonite. The introduction of a binary thickener gives the lubricant improved contact properties.
обусловленные снижением электросопротивлени .caused by a decrease in electrical resistance.
Использование одного бентонитового загустител не создает пластичной системы ввиду 5 того, что модифицированные глинистые загустители (бентониты) недостаточно хорошо набухают в нолиорганосилоксановых л идкост х. Силнкагельный загуститель придает бентонитовой смазке улучшенные реолог 1ческие 0 свойства.The use of a single bentonite thickener does not create a ductile system due to the fact that the modified clay thickeners (bentonites) do not sufficiently swell in polyorganosiloxane oils. Strong-gel thickener gives the bentonite lubricant improved rheologic properties to 0.
Применение в нластичных смазках двойных загустителей вл етс одним из путей улучшени их эксплуатационных свойств, создани смазочных материалов, обладающих одновре5 менно комплексом специфических свойств.The use of double thickeners in nlastic lubricants is one of the ways to improve their operational properties, to create lubricants that simultaneously possess a complex of specific properties.
В качестве дисперсионной среды примен ют олигонитрилсилоксановую жидкость, обладающую наибольшей элек:тронроводимостью из всех известных типов олигоорганосилоксано0 вых жидкостей (удельное объемное сопротивление ом-см). В качестве диспергаторов пластичной системы примен ют ацетон, ацетонитрил, а также бензол и толуол. В качестве присадки целесообразно в смазку вводить бензотриазол (0,1-3 вес.%), ионол (1- Звес.%).Oligonitrile siloxane liquid with the highest electrical conductivity of all known types of oligoorganosiloxane liquids (specific volume resistance ohm-cm) is used as a dispersion medium. Acetone, acetonitrile, and also benzene and toluene are used as dispersants of the plastic system. As an additive, it is advisable to introduce benzotriazole (0.1–3 wt.%), Ionol (1– Zves.%) Into the lubricant.

В аппарат с механическим перемешиванием загружают 1/3 жидкой основы нитрилполисилоксановой жидкости, добавл ют расчетное количество антиокислительных и противокоррозионных присадок, нагревают содержимое аппарата до температуры 80-100°С, при которой происходит полное растворение приса док, затем загружают оставшуюс часть жидкости , загустители и диспергатор. Всю массу загруженных компонентов выдерживают в аппарате при периодическом перемешивании в течение 4-6 час, затем 3-4 раза пропускают через гомогенизатор и фильтруют через сетку с размером чеек 60-80 мк.1/3 of the liquid base of nitrile polysiloxane liquid is loaded into the apparatus with mechanical agitation, the calculated amount of antioxidant and anticorrosive additives is added, the apparatus is heated to a temperature of 80-100 ° C, at which the complete dissolution occurs, then the rest dispersant. The entire mass of the loaded components is kept in the apparatus with periodic stirring for 4-6 hours, then 3-4 times passed through a homogenizer and filtered through a grid with a mesh size of 60-80 microns.
