  An organopolysiloxane, containing a C1-18, optionally halogenated, hydrocarbon group, is used as the fluid in a viscous coupling, with as additive: a) a phosphorus type anti-wear agent (27 formulae are given), e.g. a triaryl phosphate, optionally also with a sulfur or zinc dithiophosphate agent, each in amount of 0.01 - 5 wt %; or b) a metal deactivator, e.g. benzotriazole or other heterocylic compound or an organic acid, and or a corrosion inhibitor, e.g. a stearate, each in amount of 0.001 to 1 wt %. An antioxidant may also be added, e.g. an amine, in amount of 0.001 to 5 wt %. The fluids are exemplified as used in a coupling having 111 metal discs, with 25 to 50 rpm difference in speeds of rotation, at 130°C for up to 100 hours; they have improv­ed heat-resistance, and so suffer little change in viscosity or torque in use.

  有机聚硅氧烷含有 C1-18（可选）卤化烃基，可用作粘性偶联剂中的流体和添加剂： a) 磷类抗磨剂（给出了 27 个式），如磷酸三芳基酯，也可选择使用硫或二硫代磷酸锌 剂，每种的用量为 0.01 - 5 wt %；或 b) 金属失活剂，如苯并三唑或其他杂环化合物或有机酸，或腐蚀抑制剂，如硬脂酸 酯，每种的用量为 0.001-1 重量百分比。 还可添加抗氧化剂，如胺，添加量为 0.001 至 5 wt %。 这些润滑液可用于具有 111 个金属圆盘的联轴器中，转速相差 25 至 50 转/分，在 130°C 的温度下使用长达 100 小时；它们具有更好的耐热性，因此在使用过程中粘度或扭矩几乎不会发生变化。

  An oily lubricant for mixing with the refrigerant 1,1,1,2-tetrafluoroethane (R134a) is an ester of viscosity 2-30 mm² /s at 100°C. Suitable classes of esters are (1) polyesters of a polyol and straight or branched chain carboxylic acid (CA), (2) diesters of neopentyl glycol and a C6-9 CA, (3) complex esters of partial esters of an aliphatic polyhydric alcohol with C3-C9 fatty acids and aliphatic or aromatic di- CA, (4) C16-22 diallyl esters of aliphatic di - CA, (5) C18-26 diethyl esters of aromatic di - CA, and (6) diesters of an addition product of an alkylene oxide to a monohydric alcohol by an aliphatic di - CA. The viscosity is adjusted by using mixture of esters or by adding a polymer; suitable viscosity for a refrigerator is 2-9 mm²/s and for a car air conditioner it is 7-30 mm²/s. The ester should be purified to have a low acid number of 0.1-0.5 mg KOH (g), to prevent metal corrosion, whilst keeping high insulating property, and it is purified so as to be stable and to have no more than 500 ppm of moisture. An anti-wear agent of the sulfur type is preferably added in amount of 0.01-5 w/t%, and other additives can be an anti-oxidant and corrosion inhibitors. The lubricant has excellent compatibility with R134a, low hygroscopicity, high thermal stability and lubricating property.

  用于与制冷剂 1,1,1,2-四氟乙烷（R134a）混合的油性润滑剂是一种在 100°C 时粘度为 2-30 mm² /s 的酯类。 合适的酯类有：(1) 多元醇与直链或支链羧酸（CA）的聚酯；(2) 新戊二醇与 C6-9 CA 的二酯；(3) 脂肪族多元醇与 C3-C9 脂肪酸的部分酯与脂肪族或芳香族二 CA 的复酯、(4) 脂肪族二-CA 的 C16-22 二烯丙基酯， (5) 芳香族二-CA 的 C18-26 二乙酯，以及 (6) 脂肪族二-CA 的环氧烷与一元醇的加成产物的二酯。 粘度可通过使用酯类混合物或添加聚合物来调节；适用于冰箱的粘度为 2-9 mm²/s，适用于汽车空调的粘度为 7-30 mm²/s。 为了防止金属腐蚀，同时保持较高的绝缘性能，酯应经过提纯，使其具有 0.1-0.5 毫克 KOH（克）的低酸值。 硫类抗磨剂的添加量最好为 0.01-5w/t%，其他添加剂可以是抗氧化剂和腐蚀抑制剂。 该润滑剂与 R134a 具有良好的兼容性、低吸湿性、高热稳定性和润滑性。
