摘　　要：本文介绍了用线型低密度聚乙烯(LLDPE)进行填充发泡的试验结果。主要研究了填料用量、发泡剂及不同树脂用量与配比等对填充发泡材料的表观密度、拉伸强度和断裂伸长率等力学性能的影响。文中指出,以LLDPE树脂为主要原料配以少量的LDPE树脂制造填充发泡材料是可行的。所得泡沫塑料的主要性能接近或超过用单一LDPE制得的泡沫塑料,而且不需专用设备,用现有塑炼及层压设备即可生产LLDPE泡沫天花板,为LLDPE的应用开辟了一条新途径。通过实验,初步摸索到了制造LLDPE填充发泡材料的工艺条件和配方,为进一步进行这方面的研究工作提供了基础资料。This paper deals with the foaming of Linear Low Density polyethylene (LLDPE) with filler. The effects of the amounts of filler, foaming agent and bifferent resins used and their different ratios, etc. on the apparent density, tensile strength and elongation at rupture are mainly studied. It is pointed out that it is possible to make LLDPE foams with a small amount of LDPE. The main properties of the foams are close to or better than those of the LDPE ones. LLDPE foams can be made by using the present plasticating and laminating equipments. Special equipment is not needed in general. In the experiment, we got some useful technology data and formulas of producing LLDPE foams.
