摘要: 对乙烯基酯树脂(MFE711W型)作为树脂基体制作的小口径连续缠绕玻璃钢管道的工艺性能、玻璃钢(FRP)力学性能、耐腐蚀性能进行了研究,与不饱和聚酯树脂及乙烯基树脂/不饱和树脂混合树脂(UP/VE)进行力学性能、防腐蚀性能对比,证明MFE711FW在小口径连续缠绕管道应用上的优越性。连续缠绕工艺采用钴/过氧化甲乙酮体系,常温固化,解决了乙烯基酯树脂活性低,不适用于快速成型工艺的缺陷。

Abstract: In order to make up small diameter corrosion-resistance glass fiber rein forced plastics (GFRP) pipeline which was molded by continuous winding, the matrix properties of GFRP between viny ester resin (VE), unsaturated polyester resin (UP) and UP/VE mixture were realized in the present work. Influence factors of gel time is analyzed. The mechanical properties of different resin casting and GFRP are compared. Bending strength retention rate after immersion of corrosion medium is tested. The results show that the process performance of VE (MFE711FW resin), UP (MERICAN9708) and UP/VE mixture (weight ratio 1∶1) is comparable. The resin gel time is affected by the initiator, accelerator, accelerator assist promoter and temperature. The mechanical properties of pure resin and GFRP of VE are the best. The bending strength retention rate after 6 months immersion at 80 ℃ of VE is up to 80%, while the UP retention rate is below 20% after 2 months immersion at 80 ℃. The GFRP is apt to be damaged compared to pure resin. VE is more suitable for small diameter corrosion-resistance continuous winding GFRP pipeline.

Key words: small diameter continuous winding, vinyl ester resin, FRP pipe, corrosion resistance
