Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat insulating material.

[0002]

[Prior art]

 Conventionally, neoprene sponge rubber with closed cells is used for wet suits such as marine sports, but since these conventional sponge rubbers are not breathable even though they are known to retain heat, they are suitable for ski wear, camping equipment, etc. Expansion to land sports equipment and apparel products was restricted. This non-breathable neoprene sponge rubber has many holes with a diameter of 0.5 to 0.6 mm. This perforated rubber is breathable but has the problem of water leakage. Have Also known as synthetic fibers having the ability to exchange light with heat are Thermotron (trademark) manufactured by Unitika and Active Thermo (trademark) manufactured by Toray Industries, Inc. Furthermore, moisture is passed but water is not passed. GORE-TEX (trademark) Entrant (trademark) and the like are known as moisture-permeable films.

Each of the above products has excellent properties, but on the other hand, it does not have the properties required for each product, so that it is not universal. There is. Perforated rubber, for example, is breathable, but has the problem of water leakage.Synthetic fibers, which have the ability to exchange light for heat, allow water to pass through and breathable films keep moisture out. It has the property of passing water but not water, but it lacks heat retention.

[0004]

[Problems to be solved by the device]

 The problems to be solved are that conventional products have the ability to exchange light for heat, have the property of allowing moisture to pass through but not water, and have all the properties of excellent heat retention. Since it is not available, it is still inadequate for land sports equipment such as ski wear and camping equipment, and apparel products. The present invention solves the above problems, has the ability to exchange light with heat, has the property of allowing moisture to pass through but not water, and has all the properties of excellent heat retention. By providing materials, it is an object to provide thermal insulation materials useful for land sports equipment such as ski wear and camping equipment, and apparel products.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems and achieve the object of the invention, the heat insulating material according to the present invention is characterized in that it is configured as follows. That is, a first layer of synthetic fibers containing or adhering ceramic microparticles capable of exchanging light into heat, a second layer of moisture permeable film, and holes having a diameter of 0.5 to 0.6 mm are formed. The third layer of the closed-cell sponge rubber sheet having a large number of holes and the fourth layer of the synthetic fiber are integrally formed.

【Example】

 FIG. 1 is a structural explanatory view of one embodiment of a heat insulating material according to the present invention. Here, 1 is a synthetic fiber layer capable of exchanging light into heat, 2 is a moisture permeable film layer, 3 is a perforated rubber layer, and 4 is a synthetic fiber layer.

The first layer is a layer 1 of synthetic fibers containing or adhering ceramic microparticles capable of exchanging light for heat. Examples of the ceramic microparticles capable of exchanging light into heat include zirconium carbide. As synthetic fibers containing or adhering ceramic microparticles capable of exchanging light into heat, Thermotron (trademark) manufactured by Unitika and Solar α (trademark) manufactured by Desant using Thermotron manufactured by Unitika are used. , Active Thermo (trademark) manufactured by Toray Industries, Inc., and the like. Since such a layer 1 is provided on the outermost first layer, when it is used outdoors, it is possible to convert the sunlight light into heat to store and retain heat, which has a great heat retaining effect.

The second layer is layer 2 of the moisture permeable film. By making very small holes in the synthetic resin film, it is possible to give it the property of allowing moisture to pass but not water. Examples include GORE-TEX (trademark) Entrant (trademark) and the like. By providing the layer of the moisture permeable film as the second layer, it is possible to give the heat insulating material of the present embodiment a property of allowing moisture to pass but not water. That is, even if the first layer gets wet with water, the water is not blocked by the second layer and does not permeate to the third layer, and the moisture from the third and fourth layers passes through the second layer. It can be used freely as it can be diverged to the outside.

The third layer is a layer 3 of a closed-cell sponge rubber sheet having a large number of holes having a diameter of 0.5 to 0.6 mm. The closed-cell sponge rubber sheet does not have air permeability, but it can be provided with air permeability by forming a large number of holes having a diameter of 0.5 to 0.6 mm. The number of holes may be, for example, 16,000 holes per square meter. Examples of this rubber sheet include Bentec (trademark) and Tritex (trademark) manufactured by Yamamoto Chemical Co., Ltd. By providing the rubber sheet 3 in the third layer, moisture from the surface of the body can pass through the fourth layer, the third layer, the second layer and the first layer to diffuse to the outside.

The fourth layer is a layer 4 of synthetic fibers. As an example of the layer 4 of synthetic fibers, for example, ordinary nylon or ester jersey, knit or pile, or the like can be cited. Further, it may be a layer of synthetic fibers in which far-infrared ceramic particles are contained or adhered. Examples of the constituent material of the far-infrared ceramics include aluminum oxide, zirconium oxide, titanium oxide, barium oxide, silicon oxide and the like. By providing this 4th layer near the body, it is possible to enhance the heat retaining property, and by using far-infrared ceramics, the heat radiated from the body and the like are reflected, so that the heat retaining property is further enhanced. You can

The above-mentioned first layer, second layer, third layer, and fourth layer are integrally formed. As a method of integrally forming this, it is possible to form each layer by welding or adhering each layer.

[0012]

[Effect of device]

 Since the heat insulating material according to the present invention is configured as described above, it has the ability to exchange light with heat, has the property of passing moisture but not water, and is said to have excellent heat retaining properties. By providing a heat insulating material having all the properties, it is possible to provide a heat insulating material that is useful for land sports equipment such as ski wear and camping equipment and apparel products.
