摘要： A low-sling, high tack fiber lubricant having a final viscosity of from 50 SUS to 200 SUS characterized in that the lubricant contains: a mineral oil-vehicle; a high molecular weight oil-soluble polymer having a number average molecular weight in the range of from 3,500,000 to 7,500,000 selected from: (i) polyisobutylene homopolymer; (ii) a polymer of straight chain alpha-monoolefins/having 4 to 20 carbon atoms; and (iii) a copolymer of isabutylene and straight chain alpha-monoolefin; a low molecular weight oil-soluble polyisobutylene homopolymer having a number average molecular weight in the range of from 500,000 to 3,000,000 and an emulsifier or mixture of emulsifiers wherein the ratio by weight of component (b) to component (c) is from 9:1 to 1:9, wherein said lubricant is prepared by a process comprising selecting a mineral oil vehicle having a viscosity from about 5 to 50 SUS lower than the final viscosity of the lubricant; admixing components (b), (c) and (d) into the mineral oil vehicle to provide an admixture having viscosity of from 5 to 30 SUS above the final viscosity of the lubricant, and applying controlled low shear force to the admixture containing the polyisobutylene additive to reduce viscosity of the admixture to the final viscosity of the lubricant.
摘要翻译：一种低吊，高粘性纤维润滑剂，其最终粘度为50SUS至200SUS，其特征在于，润滑剂包含：矿物油载体; 数均分子量在3,500,000至7,500,000范围内的高分子量油溶性聚合物，其选自：（i）聚异丁烯均聚物; （ii）具有4-20个碳原子的直链α-单烯烃聚合物; 和（iii）异丁烯和直链α-单烯烃的共聚物; 数均分子量在500,000至3,000,000范围内的低分子量油溶性聚异丁烯均聚物和乳化剂或乳化剂混合物，其中组分（b）与组分（c）的重量比为9：1 至1：9，其中所述润滑剂通过以下方法制备，所述方法包括选择粘度比润滑剂的最终粘度低约5至50SOS的矿物油载体; 将组分（b），（c）和（d）混合到矿物油载体中以提供高于润滑剂的最终粘度的粘度为5至30SUS的混合物，并将受控的低剪切力施加到含有聚异丁烯的混合物添加剂以降低混合物对润滑剂的最终粘度的粘度。
