摘要
研究了采用化学发泡法进行微发泡的 Ｐ Ｐ／ Ｃａ Ｃ Ｏ３ 复合体系的注射成型工艺．复合体系中 Ｃａ Ｃ Ｏ３ 填充量可达８０ 份，当发泡剂用量为０．６ 份～１．０ 份，交联剂用量为０．１ 份～０．３ 份，成核剂适量时，所得 Ｐ Ｐ／ Ｃａ Ｃ Ｏ３ 复合材料的综合性能优良，比 Ｐ Ｐ降低成本约３０％
The injextion moulding of the microcellular PP/CaCO 3 composites which were made from mothod of chemical was studied.When the content of CaCO 3 is 80 share,the content of blister is 0.6 share^1.0 share,the content of cross linking agent is 0.1 share^0.3 share,the content of nucleating agent is adequate,the microcellular PP/CaCO 3 composite keep superior properties,reduce production costs about 30%.
