LDPE/HDPE/Surlyn共融体系的制备与研究
|
摘要
为了提高低密度聚乙烯(LDPE)导爆管的强度与耐热性,用高密度聚乙烯(HDPE)和沙林(Surlyn,Na~+)构成编号1～6配比组分共融体系,并对共融体系进行微观结构、力学性能和TG-DSC测试。实验结果表明:与LDPE(普通塑料导爆管源料)相比,共融体系断面发生变化是由于球状颗粒包覆物(不容的Surlyn相)在断面形成部分孔洞;少量Surlyn相的存在,会使共融体系强度、热分解特性出现突增;2%Surlyn和10%Surlyn的共融体系呈现多个连续的质量损失过程;利用HDPE/Surlyn改善LDPE共融体系LDPE/HDPE/Surlyn的强度、耐热性的优化配比范围为1%～10%Surlyn。
In order to improve the strength and heat resistance of low density polyethylene(LDPE) detonating tubes, the co-melting system was constructed by using high density polyethylene(HDPE) and Surlyn(Na~+) to form a blend of numbered components 1 to 6 and its microstructure, mechanical properties and TG-DSC were tested. Experimental results show: compared with pure LDPE(ordinary plastic detonating tube source material), the change in the cross section of the co-melt system is due to the formation of a partial hole in the section of the spherical particle coating(unstable Surlyn phase); the presence of a small amount of Surlyn phase will cause a sharp increase in the strength and thermal decomposition characteristics of the infused system; 2% Surlyn co-melting system and 10% Surlyn'co-melting system presents multiple consecutive quality loss processes; the optimal ratio range is 1%～10%Surlyn by using HDPE/Surlyn to improve the strength and heat resistance of LDPE/HDPE/Surlyn in LDPE co-melting system.
