Embodiment Construction
[0034] Below, in conjunction with specific embodiment, the present invention will be further described:
[0035] A kind of filler-free halogen-free flame-retardant epoxy resin composition, it comprises two components A and B, and described A component comprises:
[0036] Low halogen bisphenol A type epoxy resin 128 55-75%
[0037] Bisphenol F epoxy resin 170 5-15%
[0038] Phosphorus nitrogen series flame retardant 10-30%
[0039] Phosphate flame retardant 10-20%
[0040] The B component includes:
[0041] Polyetheramine curing agent D230 10-20%
[0042] Isophoronediamine IPDA 50-70%
[0043] N-Aminoethylpiperazine N-AEP 20-30%;
[0044] The percentages of each component are percentages by weight; the code name is GT-910B.
[0045] The composition is obtained after mixing the components A and B according to the weight ratio of 100:19-21.
