Embodiment 1
[0013] An engine oil dispersant, which is composed of base oil; polyisobutylene succinimide; sulfonate; a mixture of two components of diarylamine and hindered phenol; polyisobutylene amine. The base oil is a mixture of 150BS and 400SN and 10 centistokes. The weight ratio of the three components is 1:1:1. The mixture of diarylamine and hindered phenol needs to be mixed in advance, the weight ratio of the two components is 1:1, the temperature is controlled between 40-45° C. during mixing, and the mixture is stirred for 120 minutes. The percentage by weight of each component is: 22% of base oil; 46% of polyisobutylene succinimide; 9% of sulfonate; 14% of the mixture of diarylamine and hindered phenol; 9% of polyisobutylene amine; Base oil; polyisobutylene succinimide; sulfonate; a mixture of two components of diarylamine and hindered phenol; Between 45-55°C, stir for 90 minutes. After filtering, the product of the present invention is produced.
