Composite lubricating grease special for ship

Abstract

The invention discloses composite lubricating grease special for a ship, and belongs to the technical field of lubricating grease. The composite lubricating grease special for the ship is obtained through a reaction of following components: 80 to 90 parts of base oil, 30 to 40 parts of thickening agent, 15 to 25 parts of emulsion breaker, 3 to 6 parts of anti-wear reagent at extreme pressure, 2 to 5 parts of purification dispersing agent and 5 to 8 parts of friction modifier. The base oil is composed of polyolefin and fluorocarbon oil. The thickening agent is composite soap base thickening agent. According to the composite lubricating grease special for the ship, through the special combination of the thickening agent and the base oil, all kinds of auxiliary agents are added, the stability of the physical property of the composite lubricating grease special for the ship is guaranteed and the mechanical stability is maintained while the comparatively good physical property of the lubricating grease is guaranteed and the resistance to the extreme pressure property is improved greatly, no corrosion exists on metal, environmental protection is achieved, and good practicality is achieved.

Description

technical field

[0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a special composite lubricating grease for ships. Background technique

[0002] Grease is a thick, greasy semi-solid used for frictional parts of machinery to lubricate and seal. Also used on metal surfaces to fill voids and prevent rust; it is primarily formulated with mineral oil (or synthetic lubricating oil) and a thickener. In the marine industry, the waterproof performance of grease is required to be high. In the prior art, the traditional lubricating grease has poor adaptability to changes in the environment, which easily causes equipment failure and even casualties. Contents of the invention

[0003] Purpose of the invention: the purpose of the present invention is to provide a special composite grease for ships, so that it can overcome the defects of large changes in the physical properties of the grease, ensure the stability of the physical pr...

Examples

Embodiment 1

[0013] A special composite lubricating grease product 1 for ships, which is obtained by reacting the following components: 80 parts of base oil, 30 parts of thickener, 15 parts of demulsifier, 3 parts of extreme pressure antiwear agent, 2 parts of detergent and dispersant and friction The improver is 5 parts; the base oil is composed of polyolefin and fluorocarbon oil; the thickener is a complex soap-based thickener. Detergent and dispersant polyisobutylene succinimide. The extreme pressure antiwear agent is chlorinated paraffin or phosphate ester. The friction modifier was sulfurized cottonseed oil. Demulsifiers are condensation products of amines and ethylene oxide.

Embodiment 2

[0015] A finished product 2 of special composite lubricating grease for ships, which is obtained by reacting the following components: 80-90 parts of base oil, 40 parts of thickener, 25 parts of demulsifier, 6 parts of extreme pressure anti-wear agent, and 5 parts of detergent and dispersant and 8 parts of friction modifier; base oil is composed of polyolefin and fluorocarbon oil; thickener is complex soap-based thickener. Detergent and dispersant polyisobutylene succinimide. The extreme pressure antiwear agent is chlorinated paraffin or phosphate ester. The friction modifier was sulfurized cottonseed oil. Demulsifiers are condensation products of amines and ethylene oxide.

Embodiment 3

[0017] The finished product 1 and finished product 2 obtained in embodiment 1 and embodiment 2 were tested for physical properties respectively, and the changes in physical properties during the actual operation of the ship were detected, and it was found that the stability of finished product 1 and finished product 2 was better than that of traditional lubricating grease.
