Abstract
The invention discloses a melt-blown polypropylene material as well as a preparation method and application thereof. The melt-blown polypropylene material comprises the following components: 80-99 parts of polypropylene resin; 0.5 to 10 parts of antibacterial and antiviral electret masterbatch; 0.1 to 1 part of a free radical initiator; 0.1 to 0.5 part of a nucleating agent; 0.01 to 3 parts of anantioxidant; 0-3 parts of a lubricant. According to the invention, inorganic antibacterial and antiviral particles are introduced into melt-blown polypropylene; the material is endowed with intrinsicantibacterial and antiviral characteristics; after the melt-blown non-woven fabric is prepared, when viruses and bacteria are filtered, the viruses and bacteria remain on the melt-blown layer, the nano material on the composite material can rapidly wrap the viruses and bacteria, attack the bacteria and viruses, synergistically destroy the structure of the bacteria and viruses and block electron transfer of the bacteria and viruses, so that the effects of killing the viruses and bacteria and the like are achieved, and the material has excellent antibacterial performance and antiviral performance and high filtering efficiency.
Description
technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a melt-blown polypropylene material and a preparation method and application thereof. Background technique [0002] Melt-blown non-woven fabric is called the "heart" of medical surgical masks and N95 masks. It mainly uses polypropylene as the raw material, adopts melt-blown non-woven technology, and stretches the polymer with high-pressure and high-heat air to an average diameter of <5μm. The ultra-fine fibers in the filter material are randomly arranged and cross-arranged with the compartments to form a fiber filter layer with multiple curved channels. It has many voids, fluffy structure, and good anti-wrinkle ability. These ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the melt-blown non-woven fabric has good filterability, shielding, and heat insulation. and oil absorption.
