Abstract Sulfurized isobutylene (SIB) is widely used for extreme-pressure additive. However, the high sulfur content of SIB may cause excessive metal corrosion. Here, we present a strategy for the one-pot encapsulation of SIB in zeolitic imidazolate framework-8 (ZIF-8). The tribological properties of SIB@ZIF-8 as an oil additive was studied by a ball-on-disk reciprocating tribometer. In comparison to SIB and mechanically mixed SIB/ZIF-8, SIB@ZIF-8 displayed better inhibition of metal pairs corrosion, and exhibited higher anti-wear property and load-carrying capacity. This may be attributed to slow release of SIB from SIB@ZIF-8 during the friction process. This study broadens the tribological application of ZIF-8 and also provides a highly promising extreme-pressure additive for future industrial applications.

一锅合成SIB@ZIF-8具有增强的防腐性能和优异的润滑性能

摘要 硫化异丁烯（SIB）广泛用于极压添加剂。但是，SIB 的高硫含量可能会导致过度的金属腐蚀。在这里，我们提出了一种将 SIB 单锅封装在沸石咪唑酯骨架 8 (ZIF-8) 中的策略。SIB@ZIF-8 作为油添加剂的摩擦学性能通过球盘往复式摩擦计进行了研究。与SIB和机械混合SIB/ZIF-8相比，SIB@ZIF-8表现出更好的金属对腐蚀抑制能力，并表现出更高的抗磨损性能和承载能力。这可能是由于在摩擦过程中SIB@ZIF-8缓慢释放SIB。该研究拓宽了 ZIF-8 的摩擦学应用，也为未来的工业应用提供了一种极具前景的极压添加剂。
