Abstract

The invention provides shear thickening liquid containing SiO2 particles. A protector made from the shear thickening liquid can realize all-direction protection; in addition, the filling concentration of the shear thickening liquid needs to be considered so as to ensure the light and flexible performances of the protector; moreover, the protector still is fit with the body to play the protection role when joints stretch. Furthermore, the protector has good air permeability.

Description

technical field [0001] The invention belongs to the field of shear thickening liquid, and in particular relates to a shear thickening liquid used as a protective gear filling. Background technique [0002] Nowadays, extreme sports such as ice skating, skateboarding, parkour, etc. have become the sports that many people love. However, these sports are all dangerous. If you are not careful, you may be injured or even fractured. Although most people have appropriate protective equipment when performing the above sports, the traditional protective equipment is either too heavy to keep the action unchanged; or it is too light and thin to provide sufficient protection. [0003] By using high-concentration nano-scale particles to prepare the rheological phenomenon of the liquid, it can buffer part of the external shear force, and when the liquid is transformed into a state close to a solid, it can completely resist. It is known that the liquid prepared with high-concentration nano...
