Nanometer enhanced type fluorosilicone rubber long-acting anti-fouling flashing coating

Abstract

The invention provides a nanometer strengthening fluoride silicone rubber long-acting anti fouling and flashing coating material (nano PRTV coating material) which is used on an external insulation layer of a power system high pressure transmission and transformation device. The coating is composed of the following compositions (weight portion) of 20-40 percent of hydroxyl-fluoride containing polysiloxane, 2-5 percent of small molecular siloxane, 1-6 percent of cross linker, 0.02-1 percent of catalyst, 2-6 percent of nano silicon dioxide, 4-6 percent of decabromodiphenyl ethane, 1-2 percent of pigment and 30-50 percent of solvent. The coating provided by the invention is provided with perfect flame retardancy, solvent resistance, oil resistance, high and low temperature resistance and good self-cleaning performance. The surface of the coating material is smoother than dirt flash preventing coating material. Compared with the dirt flash preventing coating material, the coating material of the invention is greatly improved in aspects of hydrophobic migration speed, proportionality, sustainability, etc. Once filming can be realized. With the service life of more than 20 years, the coating material can be used permanently.

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and further relates to the application in the field of anti-fouling flashover on the outer insulating layer of electric equipment, which has fast, balanced and long-lasting hydrophobic migration, excellent flame retardancy and long-lasting aging resistance, Nano-reinforced fluorosilicone rubber long-acting anti-fouling flashover coating (referred to as nano-PRTV coating) with a service life of more than 20 years. technical background [0002] Applying RTV anti-fouling flashover paint on the insulating layer of power equipment has been proved to have a positive anti-fouling flashover effect. The quality of RTV anti-pollution flashover coatings varies greatly depending on the formula, and the anti-pollution flashover effect and economic benefits also vary greatly. RTV anti-pollution flashover coatings have more than 20 technical indicators, and their core indicators are: hydrophobic migr...
