Abstract

The present invention relates to modified polymer paint technology, and is especially one kind of composite anti-fouling metallic paint with nanometer particle and its preparation process. The preparation process of the composite anti-fouling metallic paint includes the following steps: 1. dissolving room temperature vulcanized silicon rubber in organic solvent xylene to form glue liquid; 2. preparing nanometer powder of silica, magnesia, titania and barium sulfate in certain weight proportion and treated with sodium laurate as organic surface treating agent, and adding the nanometer powder into the glue liquid gradually while vibrating; 3. adding small amount of dispersant, coupling agent and organic tin catalyst; and 4. setting the glue liquid and vibrating beads into vibrating bottle, adding silica, magnesia, titania and barium sulfate successively, vibrating, and filtering to obtain the slurry as the anti-fouling metallic paint.

Description

technical field [0001] The invention relates to a preparation method of a high-performance nano particle composite antifouling flashover coating. The invention belongs to the technical field of preparation technology of modified polymer paint. Background technique [0002] Pollution flashover is due to the fact that the surface of the insulating material of the power equipment is polluted by solid, liquid and gas conductors to form a dirty layer, which is wetted by fog and rain, resulting in partial discharge and increased leakage current. When the degree of wetting increases and the magnitude of the leakage current increases, the partial discharge arc increases, and the arc length reaches a critical value, and flashover occurs on the surface of the insulator. The previous anti-fouling flashover measures were manual cleaning, replacement of large creepage distance porcelain bottles, installation of sheds, and replacement of anti-fouling insulators. These measures were incon...
