Abstract

The invention belongs to the technical field of noise vibration control, and particularly relates to an oil-resistant high-temperature-resistant damping rubber, a preparation method and application thereof. The oil-resistant high-temperature-resistant damping rubber comprises 80-100 parts of nitrile butadiene rubber, 10-30 parts of chlorinated butyl rubber, 50-70 parts of a filler and 32-82 partsof an auxiliary agent. According to the damping rubber, chlorinated butyl rubber with weak polarity and nitrile butadiene rubber with strong polarity are used as blending components, so that the working temperature range of the rubber can be widened, the internal friction damping of the rubber can be greatly improved, vibration isolation effects are optimized, and the rubber has good damping and vibration isolation performance; when the rubber is used for noise reduction of a transformer and an electric reactor, outward transmission of noise can be effectively reduced, and the vibration transmission efficiency of a transformer body and an electric reactor body to an oil tank is reduced; and the rubber has good oil resistance and high-temperature resistance and can be used for a long time in insulating oil under the high-temperature condition.

Description

technical field [0001] The invention belongs to the technical field of noise and vibration control, and in particular relates to an oil-resistant and high-temperature resistant damping rubber, a preparation method and application thereof. Background technique [0002] In order to meet the requirements of long-distance and cross-regional power transmission, UHV projects continue to be constructed and developed. The working load of sound source equipment such as transformers and reactors remains at a high level all year round, and the near-field sound pressure level generated reaches 75-80dB(A) , making the substation and converter station interface face the pressure of excessive noise emission, seriously affecting the quality of life of surrounding residents. Conventional noise reduction projects generally choose to install box-in sound insulation covers or install sound barriers at station boundaries. However, practice has proved that the former hinders the daily inspection...
