Abstract

The invention relates to an impact-resistant material for human body protection, including a base material and a filler, and is characterized in that: the base material is bacterial cellulose with a three-dimensional porous structure inside, and the filler is a shear thickening liquid of a colloidal system. The thickening liquid is filled with the three-dimensional pores inside the bacterial cellulose, the mass proportion of the bacterial cellulose is 20%-35%, and the shear thickening liquid is 65%-80%. The invention also relates to a preparation method of an impact-resistant material for human body protection, comprising the following steps: obtaining a colloidal system shear thickening liquid; obtaining a wet macroporous BC film; and obtaining an impact-resistant material for human body protection. The invention uses bacterial cellulose as the base material to ensure the flexibility and comfort of the protective material; the shear thickening liquid of the colloidal system is used as the filling material, and while the protective effect is comparable to that of Kevlar fiber, it can also have excellent flexibility. ,comfortable to wear. The invention has the advantages of simple structure, low cost, easy manufacture and convenient use.

Description

technical field [0001] The invention relates to a personal protective material, in particular to an impact-resistant material for human body protection and a preparation method thereof. Background technique [0002] Bacterial Cellulose Fiber (BCF, BC for short) is a fiber with a three-dimensional polymer network structure synthesized by Acetobacter xylinum through biological fermentation. The diameter of a single fiber is about 100nm. It has extremely excellent mechanical properties and excellent Shape maintenance ability. These characteristics show that the fiber is a good energy-absorbing material and has great potential for preparing protective materials. At the same time, the BC membrane has excellent flexibility and can effectively cover the neck and joints of the human body. It has excellent mechanical properties and shape maintaining ability. These characteristics show that the fiber is a good energy-absorbing material and has the potential to prepare protective mate...
