Problems solved by technology

Because of its insufficient electrical performance, anti-pollution and anti-aging performance, it is easy to cause power outage accidents such as pulverization and pollution flashover
[0004] Chinese patent application CN1545104A discloses the application of room temperature vulcanized addition-type silicone fluororubber on insulators, but the target product cannot be obtained according to the disclosed method, and it does not belong to one-component moisture-cured fluorosilicone rubber coating, which is not suitable for insulators. surface coating

Embodiment Construction

[0049] Synthetic components

[0050] Synthesis of Component A

[0051] 1. Synthesis of A1 fluorine-containing silicone resin polysiloxane

[0052] In the flask, add 36.4 grams of methylphenyldimethoxysilane, 280.8 grams of tridecafluorooctyltrimethoxysilane, 81.6 grams of methyltrimethoxysilane, 34.1 grams of dimethylphenylchlorosilane and 310 grams of toluene Stir and mix, add 72 grams of water dropwise over 1 hour, and the dropwise addition is complete. After stirring for 30 minutes, the temperature was raised to reflux for 1 hour, 300 grams of toluene and 250 grams of water were added and the mixture was stirred and separated. The aqueous acid layer was removed, and the organic layer was neutralized with NaHCO3, dried with anhydrous sulfuric acid and filtered.

[0053] Alcohol and solvent were distilled off under normal pressure to obtain a mixture of toluene and fluorosilicone resin with a solid content of 50%. Colorless and transparent, the HO-(hydroxyl) content is ab...

Abstract

The invention relates to a preparation method of antifouling flash insulator coating which is prepared by mixing fluorine-containing polysiloxane component A, linear hydroxyl-terminated polysiloxane component B, organic and inorganic silicon dioxide taken as reinforcing material component C, functional powder material component D, cross-linking agent E, catalyst component F and tackifier component G. The method prepares the single-component moisture curing antifouling flash insulator coating which is removed alcohol and oxime by adding fluorine-containing silicon material into the hydroxyl-terminated linear silicone and the reinforcing material, and has good electrical performance and aging resistance, better antifouling flash capability and excellent hydrophobicity and hydrophobicity migration performance.

Description

technical field [0001] The invention relates to coating technology, in particular to a fluorine-containing silicone rubber condensation-cured anti-pollution flashover insulator coating and a preparation method thereof. Background technique [0002] Organosilicon anti-pollution flashover insulators are a new type of electrical insulation materials that are developing rapidly at home and abroad, especially porcelain or glass insulators, whose anti-pollution flashover performance, hydrophobicity, and hydrophobicity can reach Existing usage requirements. Due to climate change, erosion by wind, sand, snow and rain, and damage by birds, the metal cables exposed outdoors will cause surface corrosion or aging to affect their normal power transmission and transformation work, especially in disastrous weather. Affecting people's use of electricity or causing equipment damage requires the use of higher-grade composite insulation materials to solve and avoid the above-mentioned unfavor...
