Problems solved by technology

However, vaseline and hydrocarbon-based grease are mainly made of various low-melting waxes, so the dropping point is between 50 and 70°C. In the hot summer, because the steel-reinforced aluminum strand itself will generate a certain amount of heat, the anti-corrosion oil is easy to remove. Dripping from the steel-reinforced aluminum stranded wire does not have the effect of anti-corrosion, and it also increases the cost of the manufacturer and pollutes the environment.

Abstract

The invention discloses lubricating grease for protecting aluminum-conductor steel-reinforced cables and a preparation method of the lubricating grease, and relates to the technical field of chemical engineering. The lubricating grease comprises the following components in percentage by weight: 50-90% of base oil, 1-5% of isocyanate, 1-5% of fatty amine, 1-6% of aromatic amine, 1-6% of a tackifier, 1-5% of a rust inhibitor, 0.25-0.8% of an anti-oxidant and 0.04-0.08% of a metal corrosion inhibitor, wherein the base oil is mineral oil or synthetic base oil of which the temperature is 40 DEG C and the kinematic viscosity is 120-500 mm<2> / s. The lubricating grease has the advantages that the normal operation of the aluminum-conductor steel-reinforced cables in a seriously corroded offshore industry area can be guaranteed, the service lives of the aluminum-conductor steel-reinforced cables in the seriously corroded offshore industry area can be effectively prolonged, the water-resistant, rustproof and anti-corrosive functions can be realized, and the protecting requirements for the aluminum-conductor steel-reinforced cables can be ensured.

Description

Technical field: [0001] The invention relates to the technical field of chemical industry, in particular to a lubricating grease used for the protection of steel-cored aluminum stranded wires and a preparation method thereof. Background technique: [0002] ACSR is made of aluminum wire and steel wire and is widely used in overhead transmission lines. As the leading product of electric power overhead conductors, the design life of aluminum steel-cored wire is 30 years in the power sector. The service life of aluminum-steel wire is determined by the life of the steel core. The key to solving this problem is to improve the steel core corrosion performance. The steel core will be corroded under the action of moisture, chemical gas, tears and other substances in the atmosphere, and this corrosion is more serious especially in coastal industrial areas. The degree of corrosion is closely related to the composition of the material and the protection of the surface. Corrosion of s...
