Abstract

The invention relates to the field of speciality chemicals for the repair and maintenance of automotive engines, and particularly relates to an engine protective agent. The engine protective agent is characterized by comprising the following chemical components in parts by weight: 65-86 parts of secondary hydrogenation base oil, 6.1-31.2 parts of polyisobutylene-bis-succinimide, 1.0-28 parts of antioxidant, 0.1-11.9 parts of sulfurized isobutylene, 0.1-12.7 parts of ethylene oxide, 0.1-19.8 parts of ZDDP (zinc dialkyl dithiophosphate) and 0.1-6.8 parts of vegetable oil. The engine protective agent has the characteristics that (1) the unique components are adopted; (2) the formula comprising the ZDDP and the vegetable oil is adopted; (3) the polyisobutylene-bis-succinimide is adopted. The engine protective agent has the advantages that (1) the lubrication property of the engine protective agent is improved; (2) the engine protective agent has no corrosion to rubber, plastic parts and metal pieces.

Description

technical field [0001] The invention relates to the field of professional special chemicals for automobile maintenance, in particular to an engine protective agent. Background technique [0002] The technology of automobile engine is constantly improving, the size of engine is getting smaller and smaller, the control is getting more and more precise, and the requirements for lubricating oil are becoming more and more stringent. Special attention should be paid to: lubricating oil will produce acidic substances during normal use, and the existence of these acidic substances will accelerate the acidification and oxidation of lubricating oil. [0003] substances formed after combustion quantity reason water 90—120 gallons production of complete combustion unburned gasoline 3---10 gallons Rich mixture coal ash 1 / 2---2 catties substances produced by incomplete combustion Varnishes and Lipids 1 / 4---1 catties Substances that do not b...
