摘要
以聚丙烯(PP)粉料为基础原料,添加过氧化物生产无纺布专用PP树脂。研究发现:以熔体流动速率(MFR)为3.5～4.0 g/10 min的PP粉料为原料,使用固体过氧化物,生产MFR为40.0～50.0 g/10 min的无纺布专用PP树脂,生产过程平稳,产品质量能够满足要求。过氧化物的不同相态影响其在PP粉料中分散的均匀性,从而影响挤出造粒的稳定运行。
Special polypropylene（PP） resin for non-woven fabric was produced with taking PP powder as basic feedstock into which peroxide was added. The studies reveal that the production process can keep stable and the product quality can meet the requirements in the case of using the PP powder with melt flow rate （MFR） of 3.5-4.0 g/10 min as raw material and at the same time adding the solid peroxide to prepare the special resin with MFR of 40.0-50.0 g/10 rain. The peroxide has different phase states that affect its dispersion uniformity among the PP powder, thereby bringing impact on the process stability of pelletizing extrusion.
