For example, singular expressions include plural expressions unless the context clearly indicates otherwise, and expressions regarding direction are established based on the position depicted in the drawings for the sake of explanatory convenience.

[0019] FIG. 1 is a perspective view of a cooling neck band according to one embodiment of the present invention, FIG. 2 is a cross-sectional view along line AA of FIG. 1, and FIG. 3 is a cross-sectional view along line BB of FIG. 1.

[0020] As illustrated in FIGS. 1 to 3, the composition of a cooling neck band according to one embodiment of the present invention comprises an upper outer layer (11), an upper inner layer (12) forming an upper space (21) together with the upper outer layer (11), a lower inner layer (13) forming an intermediate space (22) together with the upper inner layer (12), a lower outer layer (14) forming a lower space (23) together with the lower inner layer (13), a phase change material (PCM) (40) filled in the intermediate space (22), and a superabsorbent polymer (SAP) (50) filled in the intermediate space (22) together with the PCM (30).

[0021] The above cooling neck band is formed with an outer line (31) that does not come into contact with the human body when worn on the neck of the human body and an inner line (32) that comes into contact with the human body, and the upper outer skin (11), upper inner skin (12), lower inner skin (13), and lower outer skin (14) are formed such that one end of the upper outer skin (11), upper inner skin (12), lower inner skin (13), and lower outer skin (14) is overlapped and compressed so that an outer line seam (31a) is formed protruding from the outer line (31) toward the middle space (22), and the other end of the upper outer skin (11), upper inner skin (12), lower inner skin (13), and lower outer skin (14) is overlapped and compressed so that an inner line seam (32a) is formed protruding from the inner line (32) toward the middle space (22).

[0022] The upper outer shell (11), upper inner shell (12), lower inner shell (13), and lower outer shell (14) have an injection part (33) formed protruding outward from the middle part of the outer line (31).

[0023] In the injection section (33), an upper flow path (33a) for injecting a filler into the upper space section (21), an intermediate flow path (33b) for injecting a filler into the intermediate space section (22), and a lower flow path (33c) for injecting a filler into the lower space section (23) are formed.

[0024] The above phase change material (PCM) (40) is selected from paraffin, fatty acids, and hydrated salts.

[0025] The above phase change material (PCM) (40) can store or release a significant amount of thermal energy (latent heat) during the phase change. Since it has a melting point of 18°C ​​or 28°C, when the surrounding temperature rises, such as in summer, it changes from solid to liquid later than water and melts, thereby absorbing heat for a long time and providing a cooling effect.

[0026] The above superabsorbent polymer (SAP) (50) uses sodium polyacrylate in the form of beads.

[0027] The above sodium polyacrylate is a polymer material that strongly absorbs water. It absorbs hundreds to thousands of times its own weight in water, expands, increases in volume, and simultaneously transforms into a gel form to become elastic. During the process of absorbing water, it undergoes an endothermic reaction.

[0028] The superabsorbent polymer (SAP) (50) is mixed with water in a ratio of 0.5:3, that is, a ratio less than water, and then sealed in a gel state, and when the superabsorbent polymer (SAP) (50) is frozen in a freezer, it forms into solid ice.

[0029] The above superabsorbent polymer (SAP) (50) is surrounded by a phase change material (PCM) (40), and since the melting point of the superabsorbent polymer (40) is lower than the melting point of the phase change material (PCM) (40), when the superabsorbent polymer (40) melts, it absorbs the heat of the phase change material (PCM) (40), thereby producing the effect of delaying the melting of the phase change material (PCM) (40).

[0030] Meanwhile, a plurality of through holes (not shown) may be formed in the upper outer skin (11) and lower outer skin (14) of the area that comes into contact with the human body along the inner line (32) to absorb sweat or condensation caused by temperature difference from the human body into the upper space (21) and lower space (23).

[0031] In addition, the upper space (21) and lower space (23) are filled with a powder-type superabsorbent polymer (SAP) to absorb sweat or condensation that flows into the upper space (21) and lower space (23), and by changing into a swollen gel form and storing moisture, the wearing comfort of the part that comes into contact with the human body along the inner line (32) can be improved.

[0032] The super absorbent polymer (SAP), which had absorbed moisture in the upper space (21) and lower space (23) and turned into a swollen gel state, shrinks back to its original form in powder form after the moisture evaporates after use.

[0033] In addition, a waterproof layer can be formed on the lower surface of the upper inner layer (12) and the upper surface of the lower inner layer (13) forming the intermediate space (22) to prevent leakage of moisture from the superabsorbent polymer (SAP) (50) and the phase change material (PCM) (40).

[0034] The process of forming a waterproof layer on the lower surface of the upper inner lining (12) and the upper surface of the lower inner lining (13) is as follows.

[0035] First, a silane primer layer is formed by applying a silane primer to the lower surface of the upper inner skin (12) and the upper surface of the lower inner skin (13).

[0036] Next, a waterproof layer is formed by applying a liquid waterproof coating composition consisting of liquid silicone, a fluorine-based water-repellent additive, and a fine silica filler onto a silane primer layer, and then the waterproof layer is cured.

[0037] In addition, a functional layer can be formed on the upper surface of the upper outer shell (11) and the lower surface of the lower outer shell (14) in the area excluding the part that comes into contact with the human body, to prevent insects from approaching during outdoor activities while enhancing the cooling sensation.

[0038] The process of forming a functional layer on the upper surface of the upper outer shell (11) and the lower surface of the lower outer shell (14) is as follows.

[0039] First, the upper surface of the upper outer shell (11) and the lower surface of the lower outer shell (14) are plasma treated to improve the coating adhesion.

[0040] Next, peppermint oil microcapsules are manufactured by encapsulating peppermint oil as a core in a polyurethane shell. The peppermint oil repels insects due to its menthol component and simultaneously provides a cooling effect.

[0041] In this case, to improve the thermal conductivity of the upper surface of the upper outer shell (11) and the lower surface of the lower outer shell (14), a peppermint oil microcapsule can be manufactured by adding boron nitride (BN) with a thermal conductivity of 200 to 400 W / m·K to the peppermint oil.

[0042] Next, a coating composition consisting of peppermint oil microcapsules, a silicone binder, a dispersant, and silica microparticles is formed.

[0043] Next, a coating composition is coated on the upper surface of the upper outer shell (11) and the lower surface of the lower outer shell (14) in areas excluding the parts that come into contact with the human body, and then cured at a low temperature.

[0044] Next, liquid silicone is coated onto the coating composition and then cured.

[0045] In addition, to reflect solar heat and block radiant heat in the above functional layer, titanium dioxide and hollow ceramics may be added to a coating composition consisting of peppermint oil microcapsules, a silicone binder, a dispersant, and silica microparticles.
