preparation example Construction

[0777] In the preparation process of the dilatant energy-absorbing component, other optional additives are preferably antioxidants, heat stabilizers, crosslinking agents, toughening agents, plasticizers, and foaming agents.

[0778] In the present invention, the optional fillers mainly play the following roles in the shoe material: ① reduce the shrinkage of the product, improve the dimensional stability, surface finish, smoothness and flatness or dullness of the product etc.; ②Adjust viscosity; ③Meet different performance requirements, such as improving the impact strength and compressive strength, hardness, stiffness and modulus of shoe materials, improving wear resistance, increasing heat distortion temperature, improving electrical conductivity and thermal conductivity, etc.; ④Improving pigment Excellent coloring effect; ⑤ endows light stability and chemical corrosion resistance; ⑥ acts as a compatibilizer, which can reduce costs and improve the competitiveness of shoe mater...

Embodiment 1

[0792] The flexible adaptive protector provided in this embodiment is a patella protector belt. Its inner layer is a sweat-absorbing fabric, and the inner layer fabric and another outer layer fabric are sewn together with a 2mm thick EVA sponge and a dilatant energy-absorbing component with a length of 30mm and a thickness of 5mm. The dilatant energy-absorbing component is located inside the EVA sponge. In order to prevent the dilatant energy-absorbing assembly from sliding left and right, it is also stitched and fixed on its left and right sides. The surface of the outer fabric is sewn with a piece of Velcro and a piece of elastic band. The starting point of the wool is sewn with a plastic buckle for passing through the elastic band. The plastic buckle can be attached to the fur surface of the Velcro in reverse; the inner side of the end of the elastic band (the front side when in use) can have a logo. Wherein, the dilatant energy-absorbing component is based on hybrid cova...

Embodiment 2

[0794]The flexible adaptive protective gear provided in this embodiment is a headband. The outer layer is a sweat-absorbing elastic fiber fabric sewn into a tube, and the inner core is a vitrified polyurethane sponge composite dilatant energy-absorbing component filled with polysiloxane based on dynamic covalent cross-linking of inorganic borate silicon ester bonds. The thickness of the composite is 3mm, the density is 0.3g / mL, and the hardness at rest is 15C. According to the EN1621-2012 standard method, the impact test of the dilatant energy-absorbing component of the protective gear is carried out. Using the impact energy of 10J, the measured impact force is 6.3±0.2kN, and the same parameters are measured under the same test conditions. The penetration impact force of the reference sample below is 15.2±0.3kN, and the dilatant energy-absorbing component improves the energy-absorbing performance of the product by about 58%. Under the pulling force of the elastic fabric, the ...

Abstract

The invention discloses a flexible self-adaptive protective tool which is characterized in that the flexible self-adaptive protective tool comprises an expansive flow energy absorption assembly composed of expansive flow polymers, and the expansive flow energy absorption assembly is at least combined with a fastening piece and / or a shaping piece to form the wearable protective tool; the hardness of the expansive flow energy absorption assembly is not larger than 90 A or 70 C or 50 D. And under the action of the fastening piece and / or the shaping piece, the fitting degree of the expansive flow energy absorption assembly and the protected part is not lower than 30%. The flexible self-adaptive protective tool disclosed by the invention has good protective property and comfort, and is not easy to fall off or shift.

Description

technical field [0001] The invention relates to a protective gear, in particular to a flexible self-adaptive protective gear. Background technique [0002] Sports injuries are an important problem faced by human beings, especially for sports enthusiasts, professional athletes and the elderly, and the losses caused by sports go hand in hand. Various protective gear products emerge in endlessly, but they are often bulky or inconvenient for movement, and their protective functions are also quite limited. Joints are one of the most vulnerable joints in the human body, such as knee joints, hand joints, ankles, elbow joints, etc. Some sheath products with elastic components are often used to fit and protect joints, but the protection capabilities of such products are also very limited, and they cannot cope with multi-scene transitions during exercise. Therefore, a new class of adaptive tight-fitting flexible adaptive protective gear products is needed to solve the problem of app...
