采用美国GRACE公司生产的茂金属聚丙烯(mPP)催化剂,在中国石油独山子石化公司国产第2代环管工艺聚丙烯装置上进行了高熔体流动速率mPP的生产,对产品性能进行了评价,并进行了熔喷布试生产。结果表明:生产的高熔体流动速率mPP熔体流动速率可达到150 g/min,其粉料经造粒后熔体流动速率下降约25%;与降解法熔喷料相比,高熔体流动速率mPP的结晶(熔融)温度、结晶度、灰分和挥发分质量分数明显较低,氧化诱导期相当,但混料后的高熔体流动速率mPP生产的熔喷布纤维较粗,布面偏硬,过滤效率低。
- Abstract:
-
High melt flow rate metallocene polypropylene(mPP) was produced by adopting metallocene catalyst in the 2nd generation round-pipe polypropylene unit in Dushanzi Petrochemical Company,PetroChina. The performance of the product was evaluated and the melt-blown fabric test was carried out. The results showed that the melt flow rate of mPP could reach 150 g/min, and the melt flow rate of mPP had decreased about 25% after granulation. The crystallization temperature, the mass fraction of crystallinity, ash content and volatiles of the high melt flow rate mPP were obviously lower than those of degradation melt-blown material, and the oxidation induction period was similar. However, the melt-blown fabric produced by the high melt flow rate mPP was thicker, the cloth surface was harder, and the filtration efficiency was lower.
