Embodiments of the present creation will be described below based on Figs. 1 to 3 . This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

As shown in FIGS. 1 and 2, a protective member 100 according to an embodiment of the present invention includes a soft buffer body 1 in which a soft buffer body 1 is formed by foaming a polyol composition member, and is soft. A plurality of cells 11 are formed on the surface of the buffer body 1. The polyol composition member is a shear thickening structure and has a plurality of particle members 12 uniformly dispersed therein, and the plurality of particle members 12 are cerium oxide particles. The protective member 100 has a thickness of 1 mm to 50 mm, wherein the soft buffer body 1 is agglomerated by a momentary external force F, and the plurality of granular members 12 are agglomerated from one dispersion structure to an agglutination structure for resisting instantaneous external force. .

In detail, as shown in Fig. 1, in the present embodiment, the soft cushion body 1 is a knee guard. Of course, this creation is not limited to this. The soft cushion body 1 can be formed as any wearing member to protect a specific part of the body. For example, the soft cushion body 1 is formed as a wearable protector, such as a shatter-resistant garment, a fall-proof pants, or a shatter-resistant glove that must be worn when extreme sports or riding a heavy machine. In the present embodiment, the thickness T of the protective member 100 is between 1 mm and 7 mm. Of course, this creation is not limited to this. In other embodiments, the thickness T of the protective member 100 is between 1 mm and 300 mm, and preferably, the thickness T of the protective member 100 is no more than 6 mm. This slim design is used to enhance the comfort of wearing. In addition to being formed as a wearable member for wear, the soft cushioning body 1 can be applied elsewhere as a shock absorbing cushion to protect the article or to prevent human injury. For example, a container anti-collision bag, a container inflatable bag, or a container-filled bag at the packaging level, Or anti-collision corners or anti-collision handrails on the building level.

The polyol composition member is a shear thickening structure in which the particle member 12 is uniformly dispersed in the polyol 13 to form a dispersed structure in the polyol 13, that is, a shear thickening fluid having a shear thickening phenomenon. The shear thickening fluid is one of the non-Newtonian fluids, which exists in a liquid form under normal conditions, but when subjected to an instantaneous impact or compaction, the shear thickening fluid becomes solid as hard, which may be attributed to Under the critical shear rate, the hydrodynamic force of the solid particles exceeds the repulsive force between the particles, so the particles can contact each other and combine into a cluster, and some of the fluid will enter the pores of the cluster. Further, the liquid which causes fluidity outside the particles is reduced, resulting in an increase in viscosity. In the present embodiment, the particle member 12 is a cerium oxide particle member and a cupric oxide particles, and the polyol 13 is polyethylene glycol. Of course, this creation is not limited to this. In other embodiments, the polyol 13 can be selected from other polyols such as ethylene glycol or glycerol. Preferably, the particle member 12 is a nano-formed particle member 12 having a particle size of 6 nm to 300 nm and a particle size of the alumina-oxidized particles of 35 nm to 95 nm. In general, shear thickening is only possible if certain solid particles, such as cerium oxide, are present in very high levels in liquids. However, when the cerium oxide and the aluminum oxide are neutralized, shear thickening occurs at a low solid content of about 20% by weight. In the present embodiment, the weight percent concentration of the particulate member 12 in the polyol composition member is from 10% by weight to 50% by weight.

As shown in Fig. 2, the soft cushioning body 1 is not subjected to an external force, that is, in general, the granular member 12 is uniformly dispersed in the polyol 13, and the soft cushioning body 1 is in a soft state. When subjected to an external force such as an impact, a plurality of granular members 12 are brought into contact with each other to form a cluster, which causes the viscosity of the polyol 13 to rise, so that the soft buffer body 1 is hardened and has an effect of resisting external force.

The soft cushioning body 1 can be combined with a fiber cloth to form a wearable protector in addition to the wearable protective gear alone. As shown in FIG. 3, a protective member 100a according to a second embodiment of the present invention is a fall-proof outer casing, and the same as the protective member 100 will not be described again. The difference between the two is that the protective member 100a further includes a fiber body 2, and the fiber body 2 has a plurality of fiber members 21, which are soft. The mass buffer body 1 is disposed between the plurality of fiber members 21. In detail, the fiber main body 2 may be a finished product such as clothes, gloves, a sleeve, a hat, a mask, an eye mask, a mask, a head cover, or a sock, or may be a raw material or a semi-finished product of natural cotton, hemp, silk, or snail. . In the present embodiment, the soft buffer body 1 and the fiber main body 2 are combined in such a manner that the polyol composition member and the fiber main body 2 are co-foamed, so that the polyol composition member forms a foam on the fiber main body 2 and Combine. Of course, this creation is not limited to this. The protective member 100a can exist in a form in which the foamed body is covered with the fiber main body 2, that is, the fiber main body 2 is used as an inner lining, or the foamed body is provided between the two-layered fiber main bodies 2. Further, in other embodiments, the manner in which the soft buffer body 1 and the fiber body 2 are combined may be bonded by immersing the fiber body 2 in a polyol composition member.

In summary, the protective member of the present invention can be made into various shapes by shearing the characteristics of the thickened fluid, in a soft state under normal unstressed conditions, and having good ductility. In the case of wearing, the protective member can be properly attached to the body part, which not only improves the comfort when worn, but also limits physical activity. When the protective member is subjected to an instantaneous external force, it changes from a soft state to a hard structure to resist the impact of an external force. Moreover, the protective components of this creation have excellent protection effects through the EU CE certification EN1621-1 standard and EN1621-2 standard. Therefore, the protective members of the creation are both lightweight, comfortable, and excellent in protection. In addition, by the good ductility of the soft cushioning body 1, other objects, such as fiber cloth, can be further combined to make a garment having a cushioning effect, which has both aesthetic and protective effects. More preferably, the protective member of the present invention can be used as a shock absorbing cushion to protect other fragile items, such as glass, in addition to being worn as a wearer.
