Abstract

The present invention discloses a dry outdoor type electric power complete equipment insulation casting material, which comprises the following raw materials, by weight, 100 parts of an EHL-55A modified high purity and flexibility alicyclic epoxy resin, 80-85 parts of an EHLS-60 modified methylhexahydrophthalic anhydride, 17-20 parts of an EHLP-200 reactive toughener, 0.2-0.3 part of a N,N-benzyldimethylamine accelerator, 300-350 parts of EHLA-400 coupling silicon micropowder, and 1-3 parts of an LA epoxy resin colorant. The invention further discloses a preparation method for the dry outdoor type electric power complete equipment insulation casting material. The dry outdoor type electric power complete equipment insulation casting material has characteristics of good outdoor weathering resistance, excellent mechanical performance, excellent dielectric performance and excellent heat resistance, can not deform and crack under high temperature impact and low temperature impact (-40 to 125 DEG C), and has high insulation and mechanical properties.

Description

technical field [0001] The invention relates to an epoxy casting insulating material, in particular to a dry type outdoor electrical complete equipment insulating casting material. Background technique [0002] Epoxy resin is used as casting insulation, which started around 1950 in foreign countries, but China has gradually applied it to the casting and encapsulation insulation of motors, electrical components and large electronic components since the 1970s. After decades of introduction, digestion and independent research and development, China has completed high-level research on continuous full vacuum casting and full vacuum casting technology. It realizes the air-gap-free casting product process with high degree of automation and large casting output, which creates conditions for the development of high-voltage products. At the same time, with the improvement of casting technology and equipment, higher requirements are put forward for the technology of epoxy casting ins...
