Description

technical field [0001] The invention relates to the technical field of additives, in particular to a melt blown additive and its application. Background technique [0002] Due to the particularity of the PP meltblown process, PP raw materials suitable for meltblown nonwovens must meet three conditions: (1) very high melt index (greater than 400g / 10min); (2) narrow relative molecular mass distribution (MWD); (3) The ash content is very low. Only PP raw materials with high MFR can meet the requirements of the melt blown process, produce qualified microfiber nonwovens, and reduce energy consumption. For the production of melt-blown nonwovens, if the relative molecular mass distribution is too wide and the content of low relative molecular mass PP is more, the stress cracking of PP will be more severe, and it is easy to break filaments during the production of nonwovens; ultra-high relative molecular mass PP More content will increase the viscosity of PP, and even gel particle...
