Abstract

The invention relates to the technical field of organic silicon polymer application and provides a preparation method of a shear thickening fluid. The preparation method realizes compatible matching of micro / nano-particles and a dispersion medium and improves system shear thickening effects and system storage stability. The shear thickening fluid is prepared by mixing micro / nano-particles and an organic silicon polymer, wherein a mass ratio of the micro / nano-particles to the organic silicon polymer is (1-3): (2-4). The preparation method is simple and has short preparation time. The shear thickening fluid obtained by the preparation method has stable quality, can be mass-produced easily, has low energy consumption, produces less three wastes and has a low cost. The invention also provides a use of the shear thickening fluid in a liquid protection composite material. The liquid protection composite material prepared from the shear thickening fluid has no toxicity and no pollution and is suitable for a human body and industrial production.

Description

technical field

[0001] The invention relates to the technical field of application of low-viscosity silicone oil, in particular to the preparation of a shear-thickening suspension dispersed in low-viscosity silicone oil. Background technique

[0002] The possibility of human beings facing injuries in real life is constantly increasing, and the requirements for the types and performance of protective equipment are also increasing. With the development of high-performance fiber materials, personal protective materials have also made great progress in recent years, gradually developing from the original hard and semi-rigid products to the current soft products and the latest liquid protective equipment. The field of protection has great market prospects. As a macroscopic phenomenon, the shear thickening effect of this dispersion system has long attracted people's attention, such as the blockage of transmission pipelines and the destruction of instruments, etc. In production pr...
