Problems solved by technology

[0003] At present, the use of heat-resistant grease for gap-type overhead conductors by cable manufacturers is still relatively limited. They use domestic anti-corrosion grease products instead, which are prone to excessive oil flow and high temperature under long-term high temperature conditions of 180°C and below. problems, resulting in weak anti-corrosion effect, weakened ability to resist external corrosion, and reduced service life of power lines

preparation example Construction

[0041] In the present invention, the preparation method of the polyurea-based composite thickener preferably includes the following steps: under normal pressure, add 1 / 2 base oil, p-toluidine and cyclohexylamine to the fat-making kettle, start mixing and heating , and add the adhesive; mix 1 / 2 base oil and diphenylmethane-4,4'-diisocyanate in an automatic mixer and heat; slowly add the isocyanate-base oil mixture into the fat-making kettle, mix with The organic amine-base oil mixture is fully reacted under stirring to obtain a thickener. In the present invention, the heating and mixing temperature of the 1 / 2 base oil and p-toluidine and cyclohexylamine is preferably 120~140°C; the 1 / 2 base oil and diphenylmethane-4,4'-bis The heating and mixing temperature of the isocyanate is preferably 80-120°C; the heating and mixing temperature of the two mixtures is preferably 150-200°C.

[0042] In the present invention, based on the mass parts of the base oil, the raw materials for pre...

Embodiment 1

[0062] Put 80 parts of mixed base oil, 6 parts of p-toluidine and 18 parts of cyclohexylamine into the fat-making kettle, start mixing and heating, add 3 parts of adhesive (random polypropylene) at 60°C, mix and heat to 130°C; 80 parts of mixed base oil and 36 parts of diphenylmethane-4,4'-diisocyanate are mixed and heated in an automatic mixer, and the mixture is heated to 100°C; slowly add the isocyanate-base oil mixture into the fat-making kettle, mix with The organic amine-base oil mixture is fully reacted under stirring, mixed and heated to 180°C, and continued to stir for 30 minutes; after fat formation, then add 1.6 parts of antirust agent (neutral barium dinonyl naphthalene sulfonate) and 1.7 parts of antioxidant , 3.5 parts of oil separation inhibitor (modified nano-silicon dioxide), continue to heat to about 250 ° C for 2 hours, then add 6 parts of solid filler (mica powder), and then perform cyclic shearing, homogenization and degassing treatment, Obtain heat-resist...

Embodiment 2

[0065] Put 82 parts of mixed base oil, 6.5 parts of p-toluidine and 16 parts of cyclohexylamine into the fat-making kettle, start mixing and heating, add 3.5 parts of adhesive (random polypropylene) at 60°C, mix and heat to 130°C; 82 parts of mixed base oil and 35 parts of diphenylmethane-4,4'-diisocyanate are mixed and heated in an automatic mixer, and the mixture is heated to 100°C; slowly add the isocyanate-base oil mixture into the fat-making kettle, and mix with The organic amine-base oil mixture is fully reacted under stirring, mixed and heated to 180°C, and continued to stir for 30 minutes; after fat formation, then add 1.8 parts of antirust agent (neutral barium dinonyl naphthalene sulfonate) and 1.9 parts of antioxidant , 3.8 parts of oil separation inhibitor (modified nano-silicon dioxide), continue to heat to about 250 ° C for 2 hours, then add 6.5 parts of solid filler (mica powder), and then carry out cyclic shearing, homogenization and degassing treatment, Obtain...

Abstract

The invention relates to the technical field of lubricating grease, and provides heat-resistant grease for a gap type overhead conductor, the heat-resistant grease is prepared from the following raw materials in parts by mass: 155-180 parts of base oil, 52 to 60 parts of a thickening agent, 1.5 to 2.5 parts of an antirust agent, 3-4.5 parts of an oil separation inhibitor, 1.5 to 2.5 parts of an antioxidant, 3-5 parts of an adhesive and 6-8 parts of a solid filler, wherein the thickening agent is a polyurea-based composite thickening agent and is prepared from diphenylmethane-4, 4 '-diisocyanate, p-toluidine and cyclohexylamine, the oil separation inhibitor comprises modified nano silicon dioxide, and the adhesive comprises atactic polypropylene. The heat-resistant grease for the gap type overhead conductor, provided by the invention, has excellent wide-temperature applicability and good salt mist resistance, water spraying resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a heat-resistant grease for gap-type overhead wires and a preparation method and application thereof. Background technique [0002] With the rapid development of my country's economy, especially the economy in the southern coastal areas, the amount of gap-type overhead conductors used for overhead power lines has increased sharply. Encountered various corrosion damages, seriously affecting the safety of power transmission. In order to meet the anti-corrosion and lubrication protection for gap-type overhead wires, high requirements are put forward for the grease's wide temperature applicability, salt spray resistance, water spray resistance and anti-aging performance. [0003] At present, the use of heat-resistant grease for gap-type overhead conductors by cable manufacturers is still relatively limited. They use domestic anti-corrosion grease products instead, which ar...
