A kind of superhydrophobic electric rubber and preparation method thereof

Abstract

The invention belongs to the technical field of rubber, and proposes a super-hydrophobic electric rubber, comprising: 30-50 parts of filler, 0-10 parts of sodium polyacrylate, 60-150 parts of sodium silicate, 10-12 parts by mass. Parts of dimethyldiethoxysilane, 3-4 parts of vinyl silane coupling agent, 1-2 parts of ethyl orthosilicate, 0-3 parts of pigment, 10-15 parts of white carbon black, 35-55 parts of γ ‑Trifluoropropylmethicone, 10‑15 parts hydroterminated polysiloxane, 8‑15 parts α‑vinyl‑α, ω‑dialkoxypolydimethylsiloxane, 3 parts ‑15 parts structuring control agent, 5‑12 parts vulcanizing agent, 150‑180 parts water, 5‑8 parts silica, 3‑6 parts aluminum hydroxide, 4‑6 parts polypropylene fiber, 1‑2 parts 2 , 5‑Dimethyl‑2, 5‑di-tert-butylperoxyhexane. Through the above technical solution, the problem of insufficient hydrophobic migration of rubber in the prior art is solved.

Description

A kind of super-hydrophobic power rubber and preparation method thereof technical field The invention belongs to technical field of rubber, relate to a kind of super-hydrophobic power rubber and preparation method thereof. Background technique During the long-term operation of power grid system equipment, it is often exposed to different pollution conditions, and the operating environment is very harsh. The hydrophobicity of composite insulators will be lost over time during the operation of high-voltage lines. The durability of the hydrophobicity of composite insulators in special environments such as dust and high salt spray cannot meet the requirements of anti-pollution flashover in the power grid. At present, the insulator shed is hardened, embrittled, pulverized, the mandrel is loose, pulverized and other problems eventually lead to insulator discharge, arcing, electric corrosion, and even To flashover, short-circuit rupture and other accidents. The composite ...
