Description

technical field [0001] The invention relates to the technical field of insulator surface painting, in particular to an organic composite insulator roller paint device and a roller paint process. Background technique [0002] Synthetic insulators are high-voltage insulators made of silicone rubber materials. Different types of synthetic insulators are different. Silicone composite insulators are mainly used in substations. They have good hydrophobicity, aging resistance, tracking resistance and electrical corrosion resistance. It has high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and brittle fracture resistance, light weight, convenient installation and maintenance, and the installation dimensions of the upper and lower ends are the same as those of the corresponding porcelain pillars. The installation dimensions of the insulators are the same and can be used interchangeably. Synthetic insulators are composed of...

Problems solved by technology

[0003] In the prior art, the sheds of organic composite insulators generally adopt the process of integral injection molding, so the silicone rubber sheds and mandrels must be made in one-to-one correspondence, and one mold can only produce one corresponding silicone rubber shed. It has great limitations; and before injection, the core of the insulator needs to be polished and coated with a series of operations such as adhesive. Due to the interface effect, the organic insulating layer and the surface of the core have poor adhesion, and the insulating layer is easily damaged. Affect the service life of the insulator; In addition, injection molding requires high sealing requirements, and there will be excess insulating paint on the thimble or gas injection port when demoulding, which needs to be further polished. Therefore, in fact, the molding efficiency is low and there is a certain scrap rate.

[0004] Therefore, the main structure of the umbrella shed of the existing organic composite insulator is made of silicone rubber, and the surface is dropped by hard objects, such as wind, snow, and rainstorms, the insulator is prone to cracking, and the hydrophobicity of the surface is changed. Therefore, the best The solution is to carry out surface treatment on the shed of the composite insulator to further enhance the hydrophobic, dustproof and dielectric effects of the insulator surface. At present, domestic insulator manufacturers do not have relevant research and development in this area, and need to be in line with foreign advanced surface treatment technologies.
