Wear-resistant hydraulic-oil additive composition with excellent anti-emulsifying property

Abstract

The invention relates to a wear-resistant hydraulic-oil additive composition with excellent anti-emulsifying property for a lubricating oil additive composition of a hydraulic transmission system, belonging to the technical field of a lubricating oil additive. The wear-resistant hydraulic-oil additive composition comprises an extreme-pressure anti-wear agent containing sulfur, an anti-wear agent containing phosphorus, a metal deactivator, a detergent, an anti-rusting agent and an antioxidant. The raw material contains the following components in percentage by weight: 5-20 % of extreme-pressure anti-wear agent containing sulfur, 20-55% of anti-wear agent containing sulfur, 1-10% of metal deactivator, 5-20% of detergent, 2-5% of anti-rusting agent, 12-25% of antioxidant, and the balance of base oil, and the sum of the percentage of all the components is 100%. The additive composition adopts the existing mannich amine detergent usually used in the gasoline detergent to replace polyisobutylene succinimide, alkaline calcium sulfonate and a magnesium detergent used in the traditional lubricating oil additive, and obviously improves the anti-emulsifying property of industrial wear-resistant hydraulic oil.

Description

An anti-wear hydraulic oil additive composition with excellent anti-emulsification performance technical field The invention relates to an anti-wear hydraulic oil additive composition with excellent anti-emulsification performance, is a lubricating oil additive composition used in a hydraulic transmission system, and belongs to the technical field of lubricating oil additives. Background technique At present, due to changes in refining processes and raw materials, the quality of base oils has become increasingly unstable, which poses a severe challenge to lubricating oil manufacturers and additive suppliers. As a lubricating oil additive, since polyisobutylene succinimide and basic calcium sulfonate, magnesium detergent and dispersant are used as detergent and dispersants, the phenomenon of unqualified anti-emulsification performance often occurs when base oil is blended. Therefore, the development It is of great significance to develop an additive composition with broad-s...

At present, due to changes in refining processes and raw materials, the quality of base oils has become increasingly unstable, which poses a severe challenge to lubricating oil manufacturers and additive suppliers. As a lubricating oil additive, since polyisobutylene succinimide and basic calcium sulfonate, magnesium detergent and dispersant are used as detergent and dispersants, the phenomenon of unqualified anti-emulsification performance often occurs when base oil is blended. Therefore, the development It is of great significance to develop an additive composition with broad-spectrum base oil adaptability
