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.
