Abstract

The application belongs to the technical field of materials, and relates to a method for manufacturing nano-copper antibacterial and antiviral melt-blown cloth master batches, comprising the following steps: mixing graphene, nano-copper, microporous silica and nano-microcapsule wrapping materials to obtain Nano-microcapsule-coated graphene composite material; nano-microcapsule-coated graphene composite material and polypropylene material are mixed, melted, extruded and granulated to obtain nano-copper antibacterial and antiviral melt-blown cloth masterbatch. It also relates to the application of the nano-copper antibacterial and antiviral meltblown cloth masterbatch obtained by the above manufacturing method in a meltblown cloth with antibacterial and virus inactivation properties. Using nano-copper as an antibacterial additive to form nano-microcapsule-coated graphene composite material, and forming a melt-blown non-woven fabric masterbatch with polypropylene material, can make nano-copper firmly embedded in the molecular structure of polyester fiber to form a non-dissolving type Antibacterial fibers, so that fibers and nonwovens can obtain continuous antibacterial properties.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a manufacturing method and application of a meltblown cloth masterbatch, in particular to a manufacturing method and application of a nano-copper antibacterial and antiviral meltblown cloth masterbatch. Background technique [0002] Compared with organic antibacterial agents, inorganic antibacterial agents have received extensive attention due to their stable physicochemical properties, good heat resistance, non-toxicity and low resistance to bacteria. [0003] For example, the Chinese patent application with the patent publication number CN106221014A provides a component comprising the following parts by mass: 50-65 parts of nano neodymium oxide, 8-15 parts of polypropylene, 1-5 parts of nano-copper powder antibacterial agent, 0.1-5 parts of coupling agent, 0.1-5 parts of dispersant, 2-8 parts of polypropylene wax, 50-65 parts of nano titanium dioxide antibacterial agent, 20-40 ...
