Abstract

The invention discloses a nano inorganic antibacterial fiber masterbatch and a preparation method thereof. The nano inorganic antibacterial fiber masterbatch is composed of, by weight, 1-30 parts of fiber resin, 1-50 parts of nano inorganic antibacterial powder, 1-5 parts of silicon oil, 1-10 parts of a silane coupling agent, 1-5 parts of isocyanate and 0.1-0.5 part of an antioxidant. The preparation method includes: adding the nano inorganic antibacterial powder into a sand mill, then adding the silane coupling agent, and grinding at a high speed until a paste state is achieved; adding the isocyanate, and grinding at a high speed to obtain organic-inorganic hybrid nanopowder; jointly subjecting the nanopowder and the fiber resin to twin-screw extrusion for preparing the masterbatch. The prepared nano inorganic antibacterial fiber masterbatch is widely applicable to various fibers.

Description

technical field [0001] The invention relates to the field of polymer synthesis modification and processing, in particular, the invention relates to an inorganic antibacterial fiber masterbatch and a preparation method thereof. Background technique [0002] At present, with the improvement of people's living standards, the requirements for functional fibers and their textile products are getting higher and higher, and fibers with antibacterial functions and their textile products are one of the major categories. The preparation methods of antibacterial fibers are generally divided into two types, one is wet impregnation, the fibers or their textile products are immersed in a surface treatment agent containing antibacterial agents, and then dried and cured to obtain antibacterial fibers or textiles, but their washing resistance is poor. , the antibacterial agent is easy to peel off after washing, which leads to the decline of antibacterial performance; another preparation me...
