摘　　要：研制了一种成本低、电性能优于环氧层压板的新型耐高压绝缘板。该绝缘板采用低压片状模塑料(LPMC)模压技术,经低吨位压机压制而成。当片材中树脂与填料质量比不大于1.0:1.6时,压制的绝缘板吸水率为1.9mg/g,浸水体积电阻不小于4.0×10^(13)Ω,介电常数不大于4.4,介电损耗因数不大于0.015。该绝缘板的研制将无论是从性能上还是从成本上都可以取代现有的环氧层压绝缘板。A new kind of low price and high voltage-resistant insulation board with good electric property which is prior to epoxy laminated insulation board was prepared. The insulation board applied with the technic of low pressure compression molding was compressed by low tonnage hydraulic press. When the mass ratio of resin to filling in the recipe is less than 1.0 ： 1.6, the water absorption of manufactured insulation board is 1.9 mg/g and the inundated resistance is beyond 4.0×10^13Ω. Besides, the dielectric constant is below 4. 4 and the dielectric loss is below 0. 015. This kind of insulation board, whether in electric proper- ties or in prices, may take the place of epoxy laminated insulation board in the market.
