Abstract

The invention discloses low-temperature composite calcium sulfonate-based lubricating grease and a preparation method thereof, and belongs to the technical field of lubricating grease, wherein the low-temperature composite calcium sulfonate-based lubricating grease comprises the following raw materials in parts by weight: 35-40 parts of low-temperature base oil, 1.1-1.5 parts of a converting agent, 3.5-5.5 parts of a composite thickening agent, 25-30 parts of ultrahigh-base-number synthetic calcium sulfonate, 3.5-5.5 parts of monoalkyl titanate, 1.5-2.5 parts of micro-nano borate, 1.5-2.0 parts of glacial acetic acid, 1.2-1.8 parts of cyclohexylamine, 0.5-1.5 parts of a high-temperature antioxidant, 1.0-2.0 parts of an oxidation and corrosion-resistant additive and 0.1-3.5 parts of a surfactant. By blending the low-temperature base oil, the low-temperature resistance of the lubricating grease can be improved from the raw materials, and by adding the oxidation and corrosion-resistant additive, the oxidation resistance and the corrosion resistance of the lubricating grease can be improved, so that the service life of the lubricating grease is prolonged, and the lubricating grease issuitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a low-temperature composite calcium sulfonate-based lubricating grease and a preparation method thereof. Background technique [0002] Grease English name: lubricating grease; grease thick grease like semi-solid. It is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill voids and prevent rust. It is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener. [0003] The vast majority of greases are used for lubrication and are called antifriction greases. Anti-friction grease mainly plays the role of reducing mechanical friction and preventing mechanical wear, and at the same time also plays the role of protecting against metal corrosion and sealing and dustproof. There are some greases that are primarily used to prevent rust or corrosion of metals, called protective greases. For example, th...
