| 中文摘要: |
| 钙塑复合包装材料片材的力学性能对制品性能有显著影响,其主要影响因素有加工工艺和材料配方。 实验研究了加工温度及偶联剂的种类、添加量对片材力学性能的影响。 对不同加工温度下钙塑片材的力学性能进行了测试分析,确定了最佳挤出温度为 190 ℃ 。 对不同种类及用量的偶联剂对钙塑复合包装材料的力学性能的影响进行了研究,结果表明:对钙塑材料而言,偶联剂种类对力学性能的影响很大,尤其是拉伸强度和弯曲强度,硅烷偶联剂最适合用于钙塑材料的偶联剂;偶联剂的用量对拉伸强度和冲击强度的影响很大,当其质量分数为 2. 25% 时,拉伸强度提高了 23. 24% ,冲击强度提高了近 3 倍。 |
| 英文摘要: |
| Mechanical properties of the calcium-plastic composite have great influence on containers. The main factors influencing the mechanical properties are the process and material formulations. The influence of processing temperature and the kind and dosage of coupling agent was studied. The best processing temperature was determined to be 190 ℃ by means of mechanical properties test of corrugated calcium carbonate-plastic materials processed at different temperatures. The effects of types and dosage of coupling agents on the mechanical properties of corrugated calcium carbonate-plastic materials were studied. The results showed that the type and dosage of coupling agent has great influence on the mechanical properties of the composite, especially tensile and bending strength; the silane coupling agent is the most suitable for calcium carbonate-plastic composite packaging materials; the dosage of coupling agent has great influence on tensile and bending strength; when the mass fraction of coupling agent is 2. 25% , the tensile and bending strength increase by 23. 24% , and the impact strength increases by 3 times approximately. |
