摘　　要：分别使用石蜡型、淀粉型和硅烷型浸润剂制造无碱玻璃纤维,并通过试验对比分析3种纤维的几何形貌、绝缘树脂浸润能力和拉伸性能,然后制成无碱玻璃纤维带,研究3种无碱玻璃纤维带在绝缘树脂浸透速率、表面毛刺状态和强度方面的差异。结果表明:硅烷型无碱玻璃纤维带的绝缘树脂浸透速率最大、与绝缘树脂复合后的弯曲强度最高;淀粉型无碱玻璃纤维在织带过程中产生的毛刺最少;石蜡型无碱玻璃纤维在织带过程中的强度损失最少。提出了无碱玻璃纤维带的选材原则:按照绝缘树脂浸透速率优先原则选择硅烷型玻璃纤维;按照防电晕优先原则选择淀粉型玻璃纤维;按照强度优先原则,在一般工况下选择石蜡型玻璃纤维,在严苛动载工况下选择硅烷型玻璃纤维。Alkali-free glass fibers were prepared using paraffin type,starch type,and silane type impregnating agent,respectively,and their geometric morphology,insulating resin wettability,and tensile properties were compared and analyzed.Three kinds of alkali-free glass fiber tapes were prepared,and the differences of their insulating resin impregnating rate,surface burr state,and strength were studied.The results show that the insulating resin impregnating rate of silane type alkali-free glass fiber tape is the largest,and the bending strength is the highest after compositing with insulating resin.The burr of starch type alkali-free glass fiber tape produced in the webbing process is the least,and the strength loss of paraffin type alkali-free glass fiber is the least in the process webbing.The material selection principles of alkali-free glass fiber tape is put forward.According to the priority principle of insulating resin impregnation rate,the silane glass fiber is selected.According to the priority principle of corona resistance,the starch type glass fiber is selected.According to the priority principle of strength,paraffin glass fiber is selected under general working conditions,and silane glass fiber is selected under severe dynamic load condition.
