Abstract

The invention discloses an antibacterial non-woven material and a preparation method thereof, and belongs to the technical field of non-woven material preparation. The antibacterial non-woven materialcomprises 80-120 parts of polypropylene, 0.5-2 parts of an initiator A, 0.1-2 parts of an antioxidant, 1-3 parts of an antibacterial agent, 3-10 parts of electret master batch, 0.1-2 parts of a nucleating agent and 10-20 parts of LMPP, wherein the antibacterial agent is a silver ion antibacterial agent or a zinc ion antibacterial agent; the preparation method comprises the following steps: mixing, melt extrusion, mixing homogenization and melt-blowing molding, wherein the antioxidant is added into the tenth heating section of an extruder with 13 heating sections. The antibacterial non-woven material product can be used for preparing medical consumables such as masks and operation caps, can also be used for manufacturing female hygienic products, has a long-acting and lasting antibacterialeffect, and is higher in safety when being in direct contact with skin or wounds. Besides, the antioxidant is added into the tenth heating section so that the controllability of the melt index can beimproved, the consumption of the initiator A can be reduced, and the oxidation resistance of the product can be improved.

Description

technical field [0001] The invention relates to the technical field of nonwoven material preparation, more specifically, it relates to an antibacterial nonwoven material and a preparation method thereof. Background technique [0002] Non-woven material is a kind of non-woven material processed by non-woven technology such as mechanical and thermal bonding, which is different from traditional textile technology. Low price, recyclable, non-toxic and non-irritating, etc. [0003] At present, in the field of medical supplies and women's hygiene products, non-woven materials are used on a large scale, such as masks, surgical towels, surgical caps, protective clothing, disinfection wraps, diapers, sanitary napkins, etc. Since non-woven materials used in these fields are often in direct contact with skin or wounds, it is safer for users to choose non-woven materials with antibacterial function. [0004] The Chinese patent whose notification number is CN103161071B discloses a kind...
