Fluid barrier material and preparing method of fluid barrier material

Abstract

The invention relates to the technical field of bulletproof barrier materials, and particularly discloses a fluid barrier material and a preparing method of the fluid barrier material. The fluid barrier material comprises STF, armored fabric and band adhesive tape. The armored fabric is of a three-dimensional interlayer structure and is provided with cavities, the STF is arranged in the cavities, and the armored fabric is sealed through the band adhesive tape. By means of the fluid barrier material, the compatibility and the stability of the STF and the armored fabric are improved; meanwhile, the technical problem that as the STF has the fluidity and is prone to downwards flowing under the effect of the gravity, the barrier performance at the upper portion of the armored fabric and the barrier performance at the lower portion of the armored fabric have great difference is solved, and the overall barrier performance of the fluid barrier material is improved.

Description

technical field [0001] The invention relates to the technical field of bulletproof protection, in particular to a liquid protective material and a preparation method thereof. Background technique [0002] Shear thickening fluid (shear thickening fluid, referred to as STF), is a new type of functional material, which is a slightly viscous liquid under normal conditions. When subjected to impact, a metastable "particle cluster" is generated due to fluid mechanics overcoming the repulsive force between particles. These "particle clusters" grow up with the increase of hydrodynamic force and are separated by the dispersion medium. As a result, the volume of the system becomes larger, and the macroscopic performance shows that the apparent viscosity increases sharply, even discontinuously, showing the impact resistance of a solid; and when the impact force decreases, it quickly returns to the original flexible state. reversibility. [0003] The liquid bulletproof and stabbing ma...

Problems solved by technology

[0005] The present invention aims to overcome the technical defects of poor compatibility and stability between STF liquid and protective fabric and poor protective performance in the existing liquid protective materials, improve the compatibility and stability of STF liquid and protective fabric, and solve the problem at the same time Due to the fluidity of STF, it is easy to flow downward when it is subjected to gravity, which causes a technical problem that the protective performance of the upper and lower fabrics is quite different, and improves the overall protective performance of the liquid protective material.
