摘要
采用不同粒径的碳酸钙经表面处理后填充线性低密度聚乙烯(LLDPE)制得母料。研究了偶联剂的种类及用量、密炼时间、碳酸钙粒径大小以及碳酸钙填充量对母料性能的影响。结果表明,复合型偶联剂LD-121用量为2%(质量分数,下同),对碳酸钙的处理效果最佳;密炼时间约为12 min、碳酸钙粒径大小为10.2μm、碳酸钙质量分数为75%时制得的母料综合性能最佳。
Master batch was prepared with linear low density polyethylene（LLDPE） and calcium carbonate of the surface treatment. The effects of the type and dosage of the coupling agents, mixing time, the size of fillers and the content of fillers on the performance of the master batch were studied. The experimental results show that LD-121 with the content of 2 % has the best modification effect. The performance of the master batch becomes best when the mixing time is about 12 min , the size of calcium carbonate is 10.2 μm and the content of calcium carbonate is 75 %.
