摘要
以聚乙烯(PE)、超细化氢氧化镁(MH)/PE环保阻燃母粒(或超细化氢氧化镁(MH))、尼龙6(PA6)及聚乙烯接枝马来酸酐(PE-g-MAH)为原料,采用熔融挤出法制备了聚乙烯瓦斯隔离板片材,并研究了不同原料的种类和用量对其阻燃性能、阻气性能及力学性能的影响。研究结果表明,超细化氢氧化镁(MH)/PE环保阻燃母粒复配阻燃体系具有更好的阻燃效果,且添加量低;尼龙6(PA6)和相容剂PE-g-MAH的加入明显提高了瓦斯隔离板的气体阻隔性能;制备的聚乙烯瓦斯隔离板的力学性能满足《高分子防水材料》(GB18173.1-2012)的基本要求(拉伸强度≥16 MPa,断裂伸长率≥550%)。
The PE gas isolation plate is prepared by melt extrusion method, with polyethylene（PE）, ultrafine MH/PE environment-friendly flame retardant masterbatch （ultrafine MH）, polyamide 6 （PA6）, and maleic anhydride grafted PE（PE-g-MAH） as raw materials. The effect of different kinds and contents of raw materials for its flame retardant properties, gas barrier properties and mechanical properties are characterized. The results show that. ultrafine MH/environment-ffiendly flame retardant masterbatch （MH/flame retardant masterbatch） has better flame retardant property using less than MH. Addition of PA6 and compatibilizer PE-g-MAH can obviously improve the gas barrier properties. In addition, the mechanical properties of PE gas splitter plate meets the technology requirements of stipulated in Polymer Water-proof Materials （GB18173.1-2012） which specifies that the Tensile Strength ≥16 MPa and Breaking Elongation ≥550%.
