玻璃纤维浸润剂的制备与性能
|
摘要
通过玻璃纤维浸润剂的制备,采用浸润剂中的硅烷偶联剂(KH550)进行接枝改性,并对二氧化硅进行接枝改性,探讨了制备浸润剂乳液的工艺条件等。分析了硅烷偶联剂的改性效果,制成的浸润剂乳液的性能,还分析了制备的浸润剂涂覆到玻璃纤维表面后得到的玻璃纤维的力学性能等。FT-IR测试结果表明,烯丙基聚氧乙烯聚氧丙烯环氧基醚(AEPH)已接枝到硅烷偶联剂上,硅烷偶联剂(KH550)接枝到二氧化硅上。接触角测试结果表明,二氧化硅的疏水性得到了明显改善。将改性后的硅烷偶联剂和二氧化硅加入到双酚A环氧乙烯基树脂为主成膜剂的乳液中,通过对乳液进行粒径、表面张力测试,结果表明:制备的乳液达到预期的要求。将乳液涂覆到玻璃纤维后,扫描电镜结果表明:浸润剂涂覆到了玻璃纤维表面上,且含1%改性硅烷偶联剂浸润剂比含0. 5%改性硅烷偶联剂浸润剂的涂覆厚度大。力学性能结果表明,浸润剂涂覆后,玻璃纤维的拉伸强度明显提高。
Through the preparation of the glass fiber infiltrant,the silane coupling agent( KH550) in the infiltrant for glass fiber was graft-modified,the silica was graft-modified,and the infiltrant emulsion was processed. The modification effect of the silane coupling agent,the properties of the resulting sizing emulsion,and the mechanical properties obtained by applying the prepared infiltrant to the surface of the glass fiber were analyzed. The FT-IR test results showed that allyl polyoxyethylene polyoxypropylene epoxy ether( AEPH) had been grafted onto the silane coupling agent,and the silane coupling agent( KH550) was grafted onto the silica. The angular test confirmed that the hydrophobicity of the silica was improved. The modified silane coupling agent and silica were added to the emulsion of the bisphenol an epoxy vinyl resin as the main filmforming agent,and the emulsion was granulated. The results of diameter and surface tension test showed that the prepared emulsion reached the expected requirements. The emulsion was applied to the glass fiber,and the scanning electron microscopy showed that the infiltrant was coated on the surface of the glass fiber and contained 1% modified silane coupling agent. The infiltrant was thicker than the 0. 5% modified silane coupling agent. The tensile strength of the glass fiber after the infiltrant coating was improved by mechanical properties analysis.
