中文摘要：

熔融制备了聚丁烯-1/高岭土（PB-1/kaolin）和PB-1/CaCO3纳米复合材料,分析了高岭土在PB-1中的分散情况以及高岭土和CaCO3用量对PB-1力学性能的影响.研究结果表明,当高岭土质量分数为2％时,高岭土在PB-1中分布均匀;当高岭土质量分数达6％时,出现微团聚现象.材料的拉伸强度在高岭土质量分数为5％左右时达最大值,而弯曲强度、弯曲模量和断裂伸长率在高岭土质量分数为4％左右时达最大值.在实验用量（0～20％）范围内,材料的拉伸强度、弯曲强度和弯曲模量在CaCO3质量分数为5％时达最大值,但此时断裂伸长率较小.

英文摘要：

The polybutylene- 1 / kaolin （ PB- 1/kaolin） and polybutylene- 1/calcium carbonate （ PB- 1/Ca- CO3 ） nanocomposites were prepared by melt-mixing. The dispersity of nano-kaolin and the effect of nano-kao- lin and nano-CaCO3 on the mechanical property of PB-1 were investigated. The results showed that nano-kao- lin has better dispersed in PB-1/kaolin nanocomposites when the mass concentration of nano-kaolin was 2 %, when it was 6%, ＂Reunion＂ phenomenon obviously manifested. When the mass concentration of nano-kaolin was 5%, the tensile strength was maximum, whereas the flexural strength, flexural modulus and elongation at break reached maximum when it was 4% In the experimental dosage range, when the mass concentration of nano-CaCO3 was 5 %, the tensile stren[gth, flexural strength and flexural modulus were maximum. At the same time, elongation at break was minimum.
