Abstract

The invention relates to an ultraviolet radiation resistant composite insulator material added with nano particles and a preparation method thereof. According to the preparation method, silicon rubberis taken as a unit, and<x>g is taken, 20<x>% nano SiO2 is taken, 5<x>% of hexamethyldisilazane is taken, 10<x>%-40<x>% nano TiO2 is taken, and 1<x>% of 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane istaken; a twin-roller machine is started, and after the temperature reaches 30 EDG C, the silicone rubber is placed in the middle of two rollers for mixing; after homogenization, nano SiO2 is added into silicone rubber evenly, and then the mixture is mixed by two rollers; at the same time, the hexamethyldisilazane is added three times; after all the additives are added, twin-roller mixing is carried out, nano TiO2 is uniformly added, and after the additives are added, twin-roll mixing is carried out to obtain a mixed material; the 2,5-Dimethyl-2,5-di(tert-butylperoxy)hexane is uniformly droppedon the mixed material, twin-roller mixing is carried out, a sample is shoveled, the sample is rolled into a croissant shape, the sample is placed between the rollers for mixing again, the sample is taken down, and the sample is placed between two clean PET films; and the sample is vulcanized at high temperature by using a tablet press. The addition of the nano TiO2 does not affect the hydrophobicity of the composite insulator material.

Description

technical field [0001] The invention relates to a composite insulator material resistant to ultraviolet radiation. In particular, it relates to an ultraviolet radiation-resistant composite insulator material added with nanoparticles and a preparation method thereof. Background technique [0002] Since the application of high-voltage transmission technology, porcelain insulators have become the insulation equipment for main transmission lines due to their superior insulation performance. Porcelain insulators are widely used in high-voltage direct current transmission lines due to their good insulation performance and weather resistance. However, due to the fact that porcelain insulators are wet in bad weather conditions, flashovers will occur when snow melts, posing a threat to the safety of transmission lines, and causing major economic losses and safety accidents in severe cases. Finding alternatives to porcelain insulators has become a research hotspot in the study of hi...
