摘要
通过改变注塑压力、注塑速度、模具温度、注塑温度等注塑成型工艺参数,研究了两种制样方式对改性聚酰胺(PA)6抗冲击性能的影响。结果表明:相同注塑成型工艺条件下,自带缺口试样的冲击强度都高于自制缺口的试样;注塑压力和注塑速度对自带缺口试样的冲击强度影响较大,但对自制缺口试样的冲击强度影响不大;模具温度和注塑温度对两种制样方式的PA 6的缺口冲击强度影响均较大。
The influences of two sampling preparation methods on impact performance of modified polyamide(PA)6 were investigated by changing the injection molding process parameters such as injection pressure,injection speed,mold temperature and injection temperature.The results show that the notched impact strength of the samples with built-in notched injection molding is higher than that of the samples with self-made notched injection molding under the same injection molding process parameters.Injection pressure and injection speed exert great influence on the notched impact strength of the sample with built-in notched injection and little effect on that of the sample with self-made notched injection.Both mold temperature and injection temperature affect the notch impact strength of PA 6 prepared by two sample preparation methods respectively.
