The oil specifications in China’s automotive market are mainly based on API specifications and D1 specification in China,so the evaluation of the compatibility between automotive engine seals and oil products should use ASTM D7216-22.Therefore,the evaluation method of the compatibility of lubricating oil and rubber by using ASTM D7216-22 was proposed,and the effects of common base oil,ashless dispersant and anti-oxidation and anti-corrosion agent in engine oil on rubber compatibility were evaluated.The results show that Class I and Class III base oils have an impact on the shrinkage of nitrile rubber (NBR) and polyacrylate rubber (ACM),and on the expansion of fluororubber (FKM),silicone rubber (VMQ) and polyethylene acrylate rubber (MAC),but both meet the requirements of D1-2019 specification in China for rubber compatibility.The oil-rubber compatibility of CK4 15W-40 blended with polyisobutylene succinimide ashless dispersant RHY161(macromolecule conventional type) and RHY162(macromolecule soot type) meets the requirements of D1 specification.The dibutyl dithiocarbamate with purity of 99.86% has good compatibility with five kinds of rubber sheets studied.The oil products blended with Class I base oil (MVI500),Class III base oil (VHVI6),dispersant RHY162,dibutyl dithiocarbamate (antioxidant) and other additives show good rubber compatibility.
