Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to gloves for handling refrigeration equipment, for example, when manually operating refrigeration equipment that cannot be handled with bare hands because the temperature is too low, such as valves and levers in liquefied natural gas piping systems. The present invention relates to gloves used for the purpose of protecting an operator's hands from cold and heat.

2. Description of the Related Art Hitherto, leather gloves have been used as gloves for handling such cooling and heating equipment.

0003

[Problems to be Solved by the Invention] However, when new, leather gloves have fine voids between the fibers and have high insulation properties, but at the same time, they are easily wetted and have high hygroscopic and water absorption properties, so it is difficult to absorb The moisture that has been removed will freeze when it comes into contact with the cooling equipment, resulting in poor workability such as the gloves being stuck to the equipment and becoming difficult to remove.Furthermore, repeated use not only reduces strength due to wetness, but also damages the fine particles between the fibers. This reduces air gaps and reduces heat insulation, leading to the risk of frostbite due to heat being drawn away from the fingertips in a short period of time when manually operating cooling and heating equipment.

[0004] Therefore, in order to solve the above problem, it is possible to use rubber gloves, but in this case, although the freezing of moisture on the outer surface of the gloves due to the above-mentioned hygroscopicity etc. can be prevented, the rubber gloves are It has the drawbacks of poor insulation and low strength. In particular, at low temperatures, they lose their flexibility and become extremely weak, so for example, if your gloves tear when you forcefully operate a low-temperature valve, you may end up touching the extremely low-temperature valve with your bare hands. In such a case,
There is also the risk that your hands will momentarily freeze on the low-temperature bulb and become unable to remove it from the contact surface.

[0005] An object of the present invention is to provide gloves for handling cooling and heating equipment that do not absorb moisture or water on the surface, have excellent heat insulation properties, and have sufficient strength.

[0006]

[Means for Solving the Problems] In order to achieve this object, the characteristic structure of the gloves for handling cooling and heating equipment according to the present invention includes a heat shielding layer on the outside that has water repellency and prevents ventilation and water passage. In addition to this, a reinforcing layer made of cloth is provided on the inside and is integrally constructed.

[0007]

[Function] According to the above structure, the outer heat shielding layer has water repellent properties and prevents ventilation and water passage, so that water vapor emitted from the fingers inside the glove does not pass through the glove and go out. Therefore, this water vapor does not condense or freeze on the glove surface. Furthermore, since no moisture is absorbed from the outside, this moisture does not freeze on the surface of the glove and the insulation properties of the glove do not deteriorate. Furthermore, since the inner reinforcing layer is made of cloth and is integrally overlaid on the heat shielding layer, it increases the strength of the heat shielding layer while also being flexible and does not inhibit the movement of the fingers.

[0008]

[Effects of the Invention] Therefore, the present invention prevents moisture from inside and outside of the gloves from condensing and freezing on the surface, causing the gloves to stick to heating and cooling equipment or reducing the insulation properties, unlike conventional leather gloves. Moreover, due to its excellent strength and flexibility,
It was possible to provide gloves for handling cooling and heating equipment that are safe and have good workability even after repeated use.

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. Figure 1 shows gloves for handling liquefied natural gas cooling and heating equipment. The structure of the material of this glove is shown in the partially cutaway portion of FIG. 1 and the cross-sectional view of FIG. 2. This material is integrally formed by overlapping a surface layer 1 made of synthetic resin, an aluminum vapor deposition layer 2, a protective layer 3, and a reinforcing layer 4 from the outside, and has a moisture absorbing layer 5 overlaid on the inside. 7 in the diagram
is an adhesive layer interposed between the layers to bond them together. The surface layer 1 is formed by mixing white fine powder pigment of titanium oxide as a heat-shielding ceramic filler with water-repellent white polyurethane, and has no air permeability or water permeability, and mainly absorbs radiant heat in the near-infrared region. Obstruct. The aluminum vapor-deposited layer 2 is made by vapor-depositing aluminum on one side of a polyamide film, and is mainly used to block radiant heat over almost the entire infrared region. The surface layer 1 and the aluminum vapor deposited layer 2 are laminated with an adhesive layer 7 made of an adhesive interposed therebetween to form a heat shielding layer 6 which has water repellency and blocks ventilation and water passage. The protective layer 3 is made of polyethylene and is for protecting the aluminum-deposited surface of the aluminum-deposited layer 2. The reinforcing layer 4 is made of nylon woven fabric and is formed integrally with the heat shielding layer 6 via the protective layer 3 and the adhesive layer 7 to increase the strength of the heat shielding layer 6. The moisture absorption layer 5 is made of cotton cloth and is provided along the inside, thereby preventing the inside of the glove from getting stuffy during use. As the adhesive layer 7, a polyurethane adhesive was used. This means that moisture from inside and outside the gloves will not condense or freeze on the surface, causing the gloves to stick to heating and cooling equipment or reduce their insulation properties, and because they have excellent strength and flexibility, they can be used repeatedly. The gloves are also designed to be safe and easy to work with when handling heating and cooling equipment. Table 1 shows a comparative example in which the temperature was measured by pressing the material used in this example excluding the moisture absorption layer 5 and the material of a conventional leather glove against a metal surface at -80°C. It can be seen that under the same conditions, the material according to the invention exhibits a smaller temperature drop over time than the material for leather gloves.

[Table 1]

[Another Embodiment] Each of the layers may include, for example, a fluorine-based resin as a matrix material for the surface layer 1, a filler such as zinc oxide, a polyester or polycarbonate as a film for the aluminum vapor deposited layer 2, and a protective layer 3. The reinforcing layer 4 is a woven fabric or non-woven fabric made of natural fibers such as hemp or drawn yarn such as polyester, polyethylene, polypropylene, etc. The moisture absorbing layer 5 is made of linen cloth, etc., as described in the previous embodiment. Others may be used in place of them. The moisture absorption layer 5 can also be formed into a felt shape by, for example, spraying short cotton fibers onto the reinforcing layer. Further, instead of the aluminum vapor deposited layer 2, for example, a film laminated with thin aluminum foil may be used.

As shown in FIG. 3, when the outer surface of the glove is provided with many convex portions 8 made of silicone resin or the like on the fingertips, etc., an anti-slip effect is obtained, and the contact area that comes into direct contact with the cooling and heating equipment is reduced. Since it is smaller, the influence of cold and heat can be reduced.

[0013] Furthermore, if there are seams, they may be sealed with silicone resin or the like.

The heat shielding layer 6 may be formed in a different form, such as by providing a water repellent layer on the outer surface, an aluminum evaporation layer inside the water repellent layer, and an auxiliary layer mixed with titanium oxide inside the aluminum evaporation layer. You can also.
