Description

technical field

[0001] The invention belongs to the field of polypropylene modification processing, in particular to a low-odor, high-toughness, high-electret polypropylene melt-blown material and a preparation method thereof. Background technique

[0002] In the context of the continuous raging of the new crown virus and the unrelenting protection against the epidemic, wearing a mask as an important means of protection can greatly reduce the transmission rate of the new crown virus, and it is also one of the essential protective tools for people to travel now. With the normalization of epidemic protection, people's requirements for masks are getting higher and higher. Polypropylene melt blown material is used as the raw material for the core layer of masks. Only high-quality polypropylene melt blown material can produce good filtering effect, low odor, Melt blown cloth with high toughness.

[0003] At present, the polypropylene melt-blown material on the market is mainly b...
