摘要:
采用高温凝胶渗透色谱(GPC)仪、差式扫描量热(DSC)仪、偏光显微镜等分析了热灌装饮料瓶用丙丁共聚聚丙烯(牌号PB 13 HF,简称试样1)的结构与性能,并与相应的市售产品(牌号为E 980 BHF,简称试样2)性能进行了对比分析。结果表明:试样1与试样2的相对分子质量及其分布相近;与试样2相比,试样1的熔融结晶性能略有提高,热变形温度、拉伸屈服应力、弯曲应力等刚性较好,冲击强度略低,雾度相近。
Abstract:
The structures and performances of propylene and butylene copolymerized polypropylene (PB 13 HF, referred to as Sample 1) for hot-filled beverage bottles were analyzed by high temperature gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and polarization microscope et al,and compared with the performances of the corresponding commercially available products(E 980 BHF, referred to as Sample 2).The results showed that the relative molecular mass and its distribution of Sample 1 and Sample 2 was similar.Compared with Sample 2, the melt crystallization performance of Sample 1 was slightly improved, the rigidities of heat deformation temperature, yield stress, bending modulus and so on were better, the impact strength was slightly lower, and the haze was similar.
