    • Thermoset microporous polymer lubricating compositions and methods for forming the same are disclosed. Each thermoset composition disclosed includes a thermosetting polymer that is formed into a microporous matrix capable of receiving a lubricating oil in the interconnected microscopic pores of the matrix during formation thereof, with the lubricating oil being thereafter retained in the pores until released through capillary draw, externally applied forces or elevated temperatures. Thermosetting polymers are set forth utilizing a number of different thermosetting resins, among which are polyurethanes that include an isocyanate (such as a diisocyanate), a polyol (such as a polyether-based polyol or a polyester-based polyol), and a catalyst (such as an amine or a metal salt) for forming a polyurethane polymer matrix the pores of which are filled with lubricating oil (such as a mineral oil or an ester-based synthetic oil), with surface energy modifiers (such as emulsifiers and foaming agents) also being utilized in some formulations to promote interconnected pore formation. The polyurethane matrix is formed by mixing the lubricating oil, catalyst and surface energy modifiers (if used) with the polyol to form an initial mixture, thereafter mixing the initial mixture with the isocyanate to form a final mixture, and then pouring the final mixture into a mold or utilization device (such as a bearing) where the final mixture is allowed to cure to thus form the polyurethane polymer matrix the pores of which are filled with the lubricating oil.
    • 公开了热固性微孔聚合物润滑组合物及其形成方法。 所公开的每种热固性组合物包括形成微孔基质的热固性聚合物,该微孔基体能够在其形成期间在基体的相互连接的微孔中接收润滑油,随后润滑油保留在孔中,直到通过毛细管吸附释放 施加的力或升高的温度。 使用许多不同的热固性树脂制备热固性聚合物,其中包括异氰酸酯(如二异氰酸酯),多元醇(如聚醚基多元醇或聚酯基多元醇)和催化剂( 例如胺或金属盐),用于形成聚氨酯聚合物基质,孔的孔用润滑油(例如矿物油或酯基合成油)填充,表面能改进剂(例如乳化剂和发泡剂 )也用于一些制剂以促进相互连通的孔形成。 通过将润滑油,催化剂和表面能改进剂(如果使用)与多元醇混合以形成初始混合物形成聚氨酯基质,然后将初始混合物与异氰酸酯混合以形成最终混合物,然后将最终混合物倒入 模具或利用装置(例如轴承),其中允许最终混合物固化,从而形成聚氨酯聚合物基质,其孔被润滑油填充。
