摘要
研究了油酸聚乙二醇酯对聚甲醛电学性能及力学性能的影响,实验结果表明,油酸聚乙二醇酯能极大的降低聚甲醛的体积电阻,具有优异的抗静电效果。油酸聚乙二醇酯添加量为1份时,体积电阻率降为107Ω·cm数量级,最低体积电阻率可达106Ω·cm数量级。同时,油酸聚乙二醇酯的添加提高了聚甲醛的缺口冲击韧性,但聚甲醛的强度有所下降。
The effects of oleic acid polyglycol ester on the antistatic and mechanical properties of polyoxymethylene were studied. The experimental results showed that oleic acid polyglycol ester could greatly decrease the volume resistance of polyoxymethylene and produce excellent antistatic effect. The volume resistance reduced to 10^7 Ω. cm order of magnitude when the weight loading was 1% and the minimum resistance could reach 10^6Ω. cm order of magnitude. Meanwhile, the additive of oleic acid polyglycol ester improved the notched impact toughness of polyoxymethylene, although the strength of polyoxymethylene has a little drop.
