Super-hydrophobic and anti-pollution flashover one-component adhesive, and preparation method and application thereof

Abstract

The invention relates to super-hydrophobic and anti-pollution flashover one-component adhesive, and a preparation method and application thereof, and belongs to the technical field of adhesives and coatings. The adhesive comprises the following components in part by mass: 100 parts of hydroxyl-terminated polysiloxane, 50 to 150 parts of fire retardant, 1 to 5 parts of hydrophobic enhancer, 0.2 to 2 parts of structure modifier, 3 to 15 parts of cross-linking agent, and 0.2 to 5 parts of catalyst. The method comprises the steps of performing vacuum drying treatment to the hydroxyl-terminated polysiloxane, reinforcing filler, the fire retardant, the hydrophobic enhancer and the structure modifier which are mixed for 1 to 3 hours at 80 to 150 DEG C, cooling the mixture, feeding the cross-linking agent and the catalyst to the mixture, uniformly mixing, and then obtaining the adhesive. The adhesive can be dissolved in organic solvent and then is served as coating. The adhesive has the advantages that the adhesive can be directly used, the bonding strength is high, the flame retardant rating is high, the pollution prevention effect is good, the technology is simple, the controllability is good, the adhesive can be directly used and can also be dissolved in solvent to perform coating operation, and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesives and coatings, and in particular relates to a superhydrophobic antifouling anti-flash one-component adhesive and its preparation method and application. Background technique [0002] At present, during the long-term use of power transmission and transformation equipment, the surface will be covered with a lot of solid particles such as dust, so that the surface of the power transmission and transformation equipment has a certain conductivity, so electricity will leak during use, which wastes resources and brings Certain security risks. The power required by the electric locomotive is the high-voltage single-phase power-frequency alternating current on the catenary wire, and the current enters the locomotive through the pantograph and the main circuit breaker to provide power for the locomotive. In recent years, the smog weather environment that often occurs in many places in China, the air conta...

Problems solved by technology

Commonly used RTV anti-fouling flashover coatings are mostly two-component, which need to be prepared on site when used, which is troublesome to operate. At the same time, there are disadvantages such as low hydrophobicity, low hydrophobic recovery, and no flame retardancy.

Commonly used RTV antifouling flashover coatings contain a large amount of solvents, and there are technical problems such as inconvenient transportation and storage
