摘要:
Provided is a method for preparing a grease composition, which comprises mixing grease components under high pressure and high flow rate impingement. In one embodiment, a first mixture of an amine in a lubricating base oil is mixed with an isocyanate in a lubricating base oil under high pressure and high flow impingement. In another embodiment, the mixing and reaction occurs in a reaction injection molding device. The orifice size through which each of the mixtures is introduced into a reaction/mixing zone is less than 0.030 inch (0.0762 centimeter) in diameter. The resulting grease composition is an extremely low noise grease, being virtually clear of any urea thickener particles, and/or can exhibit good high temperature resistance and mechanical stability.
摘要(中):
提供了一种制备润滑脂组合物的方法,其包括在高压和高流速冲击下混合润滑脂组分。 在一个实施方案中,润滑基础油中的胺的第一混合物在高压和高流动冲击下与异氰酸酯在润滑基础油中混合。 在另一个实施方案中,混合和反应发生在反应注射成型装置中。 将每种混合物引入反应/混合区的孔口尺寸小于0.030英寸(0.0762厘米)。 所得的润滑脂组合物是极低噪音的润滑脂,其实际上不含任何脲增稠剂颗粒,和/或可表现出良好的耐高温性和机械稳定性。
