    • A lubricant composition is disclosed comprising a superabsorbent polymer combined with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. In the composition, the material for decreasing friction comprises a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A method of lubricating a surface is also disclaosed comprising coating said surface with the lubricating composition comprising the superabsorbent polymer combined with a material for decreasing friction between moving surfaces, wherein the material for decreasing friction comprises a petroleum lubricant, water, synthetic lubricant, grease, solid lubricant or metal working lubricant, and optionally an additive.
    • 公开了一种润滑剂组合物,其包括与用于减少运动表面之间的摩擦的材料组合的超吸收性聚合物。 超吸收性聚合物在水中吸收其重量的约25至大于100倍,并且可以包含丙烯酸,丙烯酸酯,丙烯腈或丙烯酰胺的聚合物,包括其共聚物或其淀粉接枝共聚物或其混合物。 在组合物中,用于减少摩擦的材料包括含有添加剂的石油润滑剂,含有添加剂的水,合成润滑剂,润滑脂,固体润滑剂或金属加工润滑剂,其中合成润滑剂,润滑脂,固体润滑剂或金属加工润滑剂任选地含有 添加剂。 润滑表面的方法也被包括在内,包括用包含超吸收性聚合物的润滑组合物涂覆所述表面,所述润滑组合物与用于减少运动表面之间的摩擦的材料组合,其中用于减少摩擦的材料包括石油润滑剂,水,合成润滑剂, 固体润滑剂或金属加工润滑剂,以及任选的添加剂。
