Abstract
The invention belongs to the technical field of materials, and relates to a manufacturing method of nano-copper antibacterial and antiviral melt-blown cloth master batch. The method comprises the following steps of mixing and hybridizing graphene, nano-copper, microporous silicon dioxide and a nano-microcapsule wrapping material to obtain a nano-microcapsule-coated graphene composite material; and mixing and melting the nano-microcapsule-coated graphene composite material and a polypropylene material, and carrying out extrusion granulation to obtain the nano-copper antibacterial and antiviral melt-blown cloth master batch. The invention also relates to application of the nano-copper antibacterial and antiviral melt-blown cloth master batch obtained by the preparation method in melt-blown cloth with antibacterial and virus-inactivating properties. According to the method and application, the nano-copper is used as an antibacterial auxiliary agent to form the nano-microcapsule-coated graphene composite material, and the nano-microcapsule-coated graphene composite material and the polypropylene material form the melt-blown non-woven fabric master batch so that the nano-copper can be firmly embedded in a polyester fiber molecular structure to form a non-dissolution type antibacterial fiber, and then the fiber and the non-woven fabric obtain continuous antibacterial property.
Description
technical field [0001] The invention belongs to the field of material technology, and relates to a method and application of a melt-blown cloth masterbatch, in particular to a manufacturing method and application of a nano-copper antibacterial and antiviral melt-blown cloth masterbatch. Background technique [0002] Compared with organic antibacterial agents, inorganic antibacterial agents have received extensive attention due to their stable physical and chemical 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 mass parts: 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 parts of ...
