Insulation material formulation and production process

  1 low voltage insulation material

  1.1 recipe

  Epoxy Resin E-44 100

  Diluent dibromophenyl glycidyl ether

  Flame Retardant Antimony Trioxide 10

  Activated silicon powder 400 mesh 200

  Curing agent 593 25

  Diethylenetriamine 3

  1.2 production process

  1.2.1 silicon powder drying to moisture content of 0.2% or less

  1.2.2 in the following order plus epoxy resin, thinner, flame retardant, silicon powder to the reactor

  1.2.3 heated to 100 ≧, in -0.1Mpa vacuum degassing under the material 30min to uniform

  1.2.4 cooled to 50 ≧ below, adding curing agent to keep the temperature does not exceed 50 ≧, degassing vacuum -0.1Mpa, mixing time of not more than 30min, you can enter the casting process.

  2. High pressure low voltage insulation material

  2.1 recipe

  Epoxy Resin E-44 100

  Diluent dibromophenyl glycidyl ether

  Flame Retardant Antimony Trioxide 10

  Activated silicon powder 400 mesh 300

  Curing agent S101 95

  Accelerator DMP-30 1.5

  2.2 production process

  2.2.1 silicon powder drying to moisture content of 0.2% or less

  2.2.2 in the following order dubbed two components

  A component epoxy resin, accelerator, flame retardant, silicon powder 200

  B component curing agent, thinner, silicon powder 100

  2.2.3 A component temperature to 80-100 ≧, in -0.1Mpa vacuum degassing under the material 30min to uniform

  2.2.4 B component temperature to 50 ≧, in -0.1Mpa vacuum degassing under the material 30min to uniform

  2.2.5 cooling to 50 ≧ below, the A component into the B component, keep the temperature does not exceed 50 ≧, degassing vacuum -0.1Mpa, mixing time 30min, you can enter the casting.
