摘　　要：为了分析改性GCC在不同粒径的情况下,对纸张的抗张强度、撕裂强度以及耐破强度等物理性能的影响,在相同改性条件下,将淀粉-硬脂酸钠复合物包覆GCC,筛分出粒径大小范围为(18.568 29.929)μm、(29.92935.155)μm、(35.155 38.985)μm、(38.985 43.135)μm、(43.135 54.025)μm、(54.025 61.113)μm、(61.113 74.137)μm、>74.137μm的八种试样。结果表明,当粒径在(35.155 54.025)μm时,纸张抗张、撕裂以及耐破强度指标最好。Modified GCC in different particle sizes was put into paper, the effects on tensile, tear and burst strength and other properties of the paper were studies. In order to analyze what will happen, using starch - sodium stearate complexes coated GCC,8 samples were classified according to the particle size range from 18. 568micrometer to 74. 137micrometer under certain conditions. The results show that when the particle size is from 35. 155micrometer to 54. 025micrometer,the paper tensile, tear and burst indexes were the best.
