Problems solved by technology

[0003] The existing RTV anti-fouling flashover coating is a new material that has emerged in recent years to improve the insulation level of electrical equipment. The service life of the RTV coating was five years at first. With the advancement of technology, the product performance has been further improved. The service life has also been increased to ten years, but this has reached the limit service life of RTV paint

Abstract

The invention discloses monocomponent PRTV anti-pollution-flashover paint and a preparation method thereof. The monocomponent PRTV anti-pollution-flashover paint is composed of the following materials in parts by weight: 28-38 parts of polydimethylsiloxane, 10-19 parts of hydroxyl-terminated fluorine-containing polysiloxane, 3-5 parts of nanometer silica, 1-3 parts of a coupling agent, 0.5-1 part of a catalyst, 2-3 parts of decabromodiphenyl ether, 1-2 parts of a pigment and 40-50 parts of a solvent. The monocomponent PRTV anti-pollution-flashover paint has the beneficial effects that a fluorine material and a nanometer material are organically combined and blended with silicone rubber, silicone rubber is taken as main base rubber and fluorosilicone rubber is taken as auxiliary base rubber; and the monocomponent PRTV anti-pollution-flashover paint has the main technical advantages of being good in flame retardant effect, substantially reduced in cost.

Description

technical field [0001] The invention relates to the technical field of insulating material production, in particular to a single-component PRTV antifouling flashover coating and a preparation method thereof. Background technique [0002] Electrical equipment arranged outdoors is easily affected by the environment, and its insulation level is likely to decrease in extreme cases, leading to electrical insulation failure. Therefore, how to improve the adaptability of outdoor electrical equipment insulation to the environment has become one of the concerns of electrical equipment maintenance personnel. Of course, the first consideration is to consider the atmospheric environment of electrical equipment at the design stage and to select the equipment in a targeted manner. However, as the equipment is put into operation, the insulation level of the equipment will age and decrease, and the environment in which the equipment is located Changes, as well as the quest for increased eff...
