Embodiment 6

[0083] The main material is 100 parts by weight of hydroxyl-terminated polydimethylsiloxane;

[0084] Reinforcing materials are white carbon black and MQ resin, the dosage is shown in Table 1

[0085] (1) Premixing of base rubber: fully mix the main material, white carbon black and flame retardant in the reaction kettle according to the selected parts by weight, the stirring rate is 400 rpm, and the stirring time is 4h to obtain the mixture;

[0086] (2) Low molecular weight removal: Stir the mixture under vacuum at 100-150°C for 2 hours to obtain a premix;

[0087] (3) Blending of cross-linking agent and catalyst: add selected cross-linking agent and catalyst in parts by weight to the premix, and continue to mix and stir, the stirring speed is 400 rpm, and the stirring time is 2h to obtain the intermediate material .

[0088] (4) Mixing of diluent and MQ resin: add selected diluent and MQ resin in parts by weight to the intermediate material, and fully mix and stir at a sti...

Abstract

The invention discloses an anti-haze and anti-pollution-flashover coating as well as a preparation method and an application thereof and belongs to the technical field of chemical coatings. White carbon black and MQ resin are taken as reinforcing materials of the anti-haze and anti-pollution-flashover coating. Compared with the traditional RTV (room temperature vulcanization) silicone coatings, the anti-haze and anti-pollution-flashover coating has double-phobic technological advantages including hydrophobic and oleophobic, has a self-cleaning function on dust particulate matters, can prevent adhesion of organic fouling, resists weather and salt-spray corrosion, thereby having the anti-haze performance..

Description

technical field [0001] The invention belongs to the technical field of chemical coatings, and in particular relates to an anti-fog and haze anti-pollution flashover coating and a preparation method and application thereof. Background technique [0002] The electric power industry is the foundation of national security and industrial and agricultural development. Therefore, the safe operation of electric power equipment and transmission and transformation circuits is very important. In practical applications, in addition to carefully considering the configuration of substations and transmission and transformation circuits, it is also a common method to apply anti-pollution flashover insulating coatings on insulating equipment, such as insulators and insulating sleeves. Among the anti-pollution flashover insulating coatings applied outside insulating equipment, room temperature vulcanized silicone rubber (RTV) is the most used base material, such as RTV-I, RTV-II, PRTV and oth...
