preparation example Construction

[0037] The preparation process of shear thickening liquid in step 2 comprises the following steps:

[0038] Step 201: gradually adding nano silicon dioxide particles into polyethylene glycol and stirring continuously;

[0039] Step 202: dispersing the mixed suspension obtained in step 201 by ultrasonic waves;

[0040] Step 203: Put the dispersed mixed solution obtained in step 202 into a vacuum drying oven to evacuate to remove air bubbles to obtain a shear thickening solution.

[0041] Step 3: Mix silicone rubber 1 with two different components in a ratio of 1:1. After removing air bubbles, dip-coat the surface of the warp-knitted spacer fabric in step 1, and then perform curing treatment to form an anti-leakage pocket spacer fabric;

[0042] Step 4: Pour the shear thickening liquid 3 in step 2 into the middle layer 23 of the bagged spacer fabric in step 3, and then use step 3 to mix the silicone rubber of two different components in a ratio of 1:1 Sealing is carried out t...

Abstract

The invention relates to the technical field of a protection structure, in particular to a shock-resisting flexible protection structure and also provides a manufacturing method of the shock-resisting flexible protection structure. The shock-resisting flexible protection structure comprises silicone rubber, a three-dimensional warp-knitted spacer fabric and a shear thickening solution, wherein the shear thickening solution comprises nano silicon dioxide particles and polyethylene glycol, the shear thickening solution is filled in an intermediate layer of the warp-knitted spacer fabric, the silicone rubber is used for packaging two sides and periphery of the warp-knitted spacer fabric to form a leak-proof bagged sealing structure. By utilizing the nano silicone dioxide particles, the thickening effect of the shear thickening solution can be adequately played, the nano silicon dioxide particles can be instantaneously converted from liquid state to solid state when suffering the shock effect, and the intelligent conversion is realized; by utilizing the warp-knitted spacer fabric, the entire flexible protection structure is stable, the mechanical property is excellent, and the shock-resisting flexible protection structure can be used for bending parts and curve structure parts such as joints.

Description

Technical field: [0001] The invention relates to the technical field of protective structures, in particular to an impact-resistant flexible protective structure, and also provides a manufacturing method of the impact-resistant flexible protective structure. Background technique: [0002] The human body often causes self-injury due to falls, slips and collisions with foreign objects during exercise and the use of various precision electronic instruments. In order to prevent various accidents, various protective structures have appeared, so that they can play a certain role in cushioning and shock absorption when they are impacted, thereby reducing the peak impact force and reducing the damage to human bodies and objects. There are three types of protective structures currently in use: rigid, semi-rigid and flexible. Among them, the hard and semi-rigid materials will restrict the individual's activities during use, and bring a lot of inconvenience during use. Although the f...
