Problems solved by technology

[0004] However, the existing cushioning technology for footwear mainly has the following limitations: the current cushioning structures and materials achieve the purpose of cushioning by deforming and prolonging the time of impact; The deformation of the foot will make the foot become unstable at the moment of contact with the ground, which increases the chance of knee and ankle injuries
Therefore, the cushioning function of existing footwear needs to be improved

preparation example Construction

[0026] The non-Newtonian fluid materials involved in the embodiments of the present application can be prepared by conventional methods in the art, or commercially available materials can be used, and there is no special limitation on its composition. Regarding the preparation method of non-Newtonian fluid materials, you can refer to a preparation method of a shear thickening liquid in the Chinese patent document of patent number ZL201410009134, which includes the following steps:

[0027] Mixing the non-volatile liquid medium and the volatile solvent evenly to obtain a mixed solution;

[0028] adding nanoparticles into the mixed solution, stirring and dispersing to form an emulsion; and removing the volatile solvent in the emulsion to obtain the shear thickening liquid.

[0029] In some embodiments, the mass ratio of the non-volatile liquid medium to the volatile solvent is between 1 / 2˜1 / 6.

[0030] In some embodiments, the non-volatile liquid medium is at least one of ethyl...

Embodiment 1

[0060] Embodiment 1 Shock-absorbing component preparation

[0061] The non-Newtonian fluid material is made according to the method of the examples in the above-mentioned patent documents, and the main component is inorganic micro-nano particles, and the inorganic micro-nano particles are SiO 2 , the particle size range of inorganic micro-nano particles is 50-900nm; the viscosity of the non-Newtonian fluid is 50000Pa·s at 25°C.

[0062] Material A is a mixture containing polyether polyols, catalysts, etc., including the above-mentioned non-Newtonian fluid and dimethylsiloxane; material B is MDI. The total pouring amount of materials A and B: 5-30 grams (adjust the pouring amount according to the size and specifications of different parts); the pouring time is 1-6 seconds. The preparation process is as follows:

[0063] Picking materials → mold preheating, filling A and B tanks → preparation, mixing, circulation → test machine, adjusting the pouring amount of A and B materials ...

Embodiment 2

[0070] The sole structure of embodiment 2 application

[0071] The shock-absorbing part (hardness 40C) prepared in Example 1 is attached to the heel of the EVA foam midsole; wherein, the midsole hardness is 55C, and the midsole thickness is as follows: Figure 4 As shown, the maximum thickness of the forefoot is 15.71mm, and the maximum thickness of the heel is 28.06mm.

[0072] Assemble the midsole into conventional shoes for plantar pressure test, the test results can be found in Figure 5 . Figure 5 Among them, ESA stands for sole with shock-absorbing parts, RF is a kind of cushioning material, the full name is REBOND FOAM, and the thickness of the test sample is the same as ESA. The experimental equipment for the test is the novel plantar pressure testing instrument. The test method is to put the insole with a sensitive sensor into the shoe, and then the subject moves at a constant speed to record the force on the plantar during the exercise.

Abstract

The invention relates to the technical field of footwear products, and provides a shoe sole using a non-Newtonian fluid material, and a sneaker. The shoe sole comprises a midsole, wherein the midsoleis provided with a shock absorption part, and the shock absorption part is a non-Newtonian fluid polyurethane part. According to the invention, the excellent shock absorption performance of a non-Newtonian fluid is fully utilized, and the non-Newtonian fluid is combined with polyurethane to manufacture the shock absorption part for the shoe sole. The shoe sole provided by the invention comprises the non-Newtonian fluid polyurethane shock absorption part, and the characteristic that non-Newtonian fluid hardens instantly when being impacted is fully reserved, so a shoe is not deformed basicallyat the moment of touching the ground, a perfect ground touching shape can be kept, stable ground touching of all joints of the feet of a user is achieved, and the injury probability of knee joints andankle joints is better reduced. Detection data show that the shock absorption effect of the non-Newtonian fluid polyurethane part is improved by 15% or above compared with the shock absorption effectof an existing shock absorption material.

Description

technical field [0001] The present application relates to the technical field of footwear products, in particular to a shoe sole and sports shoes using non-Newtonian fluid materials. Background technique [0002] In the process of running and other sports, due to the effect of inertia, the moment the bottom of the athlete's shoes touch the ground, the ground will produce a counter-impact force on the soles (generally equivalent to 3-5 times the body weight), and this huge impact force is very easy to give Some injury to the athlete's knee and / or ankle. Shoes are foot articles for people to protect feet and other parts from being injured, and the shock-absorbing or shock-absorbing function of shoes is very important and necessary. [0003] At present, many shoes on the market adopt the technology of improving the shock-absorbing performance of the sole. One method is to use a high elastic material to make the cushioning midsole; the other method is to use various cushioning...
