一种碳酸钙填充改性的线性低密度聚乙烯薄膜及其制备方法
摘要：
本发明涉一种碳酸钙填充改性的线性低密度聚乙烯薄膜，由以下组分制成：线性低密度聚乙烯55-80份，滑石粉25-35份，碳酸钙45-55份，硬脂酸钙3-5份，偶联剂1.1-1.6份，硼酸0.7-2.5份，改性剂0.7-1份，抗氧剂0.7-1.5份；该薄膜具有拉伸强度高、横向断裂伸长率高、直角撕裂强度好等优点。
摘要（英）：

The invention relates to a calcium-carbonate-filling-modified linear low density polyethylene film and a preparation method thereof. The calcium-carbonate-filling-modified linear low density polyethylene film is prepared from 55-80 parts of linear low density polyethylene, 25-35 parts of French chalk, 45-55 parts of calcium carbonate, 3-5 parts of calcium stearate, 1.1-1.6 parts of coupling agent, 0.7-2.5 parts of boric acid, 0.7-1 part of modifier and 0.7-1.5 parts of antioxidant. The film has the advantages of high tensile strength, high transverse elongation at break, favorable angle tear strength and the like.
