Description
本考案は、放射線遮蔽用素材に関し、詳しくは重量が軽く且つ柔軟性を有する放射線遮蔽用素材に関するものである。 The present invention relates to a radiation shielding material, and more particularly to a radiation shielding material that is light in weight and has flexibility.
人体に有害な量の放射線から人体を保護する手段として、重金属であり放射線遮蔽効果を有する鉛が用いられている。例えば、放射線防護服は、一般に塊状やチップ状の鉛が生地と生地との間に密封されるように縫い付けられている。しかし、このような防護服は、鉛の比重が重いため、非常に重い上に、生地の柔軟性も損われるので、着心地が悪いどころではなく身動きすら取りにくくなる。故に、このような防護服は、日常生活で着られる様なものではなく、もっぱら緊急災害時など特殊な状況で用いられるのみである。しかし近年、放射線に被爆する危険性は特殊な状況のみならず日常生活の範囲にも潜んでいる。よって、日常的にも着られるような、一般の生地とあまり変わらない重さと柔軟性を保ちながらも、放射線遮蔽効果を持つ素材が求められている。 As a means for protecting the human body from a harmful amount of radiation to the human body, lead which is a heavy metal and has a radiation shielding effect is used. For example, radiation protective clothing is generally sewn so that massive or chip-like lead is sealed between the fabrics. However, such a protective garment has a high specific gravity of lead, so it is very heavy, and the flexibility of the fabric is also lost. Therefore, such protective clothing is not something that can be worn in daily life, but is only used in special situations such as during emergency disasters. However, in recent years, the danger of being exposed to radiation is lurking not only in special situations but also in the scope of daily life. Therefore, there is a demand for a material having a radiation shielding effect while maintaining the same weight and flexibility as ordinary fabrics that can be worn on a daily basis.
本考案は、上記事情に鑑みてなされたものであり、その目的は、軽量で且つ柔軟性を有する放射線遮蔽用柔軟性素材の提供にある。 The present invention has been made in view of the above circumstances, and an object thereof is to provide a radiation shielding flexible material that is lightweight and flexible.
上記目的を達成するために、本考案は、以下の放射線遮蔽用柔軟性素材を提供する。 In order to achieve the above object, the present invention provides the following radiation shielding flexible material.
本考案に係る放射線遮蔽用柔軟性素材は、可撓性を有すると共にその内外に多数の孔や空隙が存在している基布と、鉛粉と粘着剤とから混合されてなり、前記鉛粉が散在して前記基布の孔や空隙に嵌まりこむように前記基布の表面側に敷設されている鉛含有層とを有することを特徴とする。 The flexible material for shielding radiation according to the present invention is a mixture of a lead cloth and a pressure sensitive adhesive, and a lead cloth having a large number of holes and voids inside and outside, and the lead powder. And a lead-containing layer laid on the surface side of the base fabric so as to fit in holes and voids of the base fabric.
また、上記構成において、前記鉛含有層は、その含有する前記鉛粉および前記粘着剤のほぼ全てが前記基布の孔や空隙に嵌まりこんで、前記基布の表面近くにある内部構造と密接に結合して一体になっていてもよい。この場合、鉛含有層の敷設方法としてはローラープレスによる押圧加工を用いると好ましい。 Further, in the above configuration, the lead-containing layer is in close contact with an internal structure near the surface of the base fabric, in which almost all of the lead powder and the pressure-sensitive adhesive contained in the lead-containing layer fit into holes or voids of the base fabric. May be combined into a single unit. In this case, it is preferable to use pressing by a roller press as a method for laying the lead-containing layer.
また、前記鉛含有層は、前記基布の表面付近に位置する前記鉛粉が前記基布の表面における孔や空隙に嵌まり込むように、前記基布の表面と密に接していてもよい。この場合、鉛含有層の敷設方法としては浸染、コーティング、一体射出成形を用いると好ましい。 The lead-containing layer may be in intimate contact with the surface of the base fabric so that the lead powder located near the surface of the base fabric fits into holes or voids in the surface of the base fabric. . In this case, as a method for laying the lead-containing layer, it is preferable to use dip dyeing, coating, or integral injection molding.
更に、本考案は、上記の放射線遮蔽用柔軟性素材が数枚重なってなる放射線遮蔽用柔軟性素材をも提供する。 Furthermore, the present invention also provides a radiation shielding flexible material in which the radiation shielding flexible material is overlapped.
また、上記いずれかの放射線遮蔽用柔軟性素材は、更にカバー層に包まれているとよい。 In addition, any of the above-described flexible materials for shielding radiation may be further wrapped in a cover layer.
上記いずれの放射線遮蔽用柔軟性素材によっても、鉛粉を有する鉛含有層が、基布と全体的にあるいは部分的に一体となるように敷設され、鉛粉が基布における孔や空隙に嵌まり込むように散在しているので、放射線遮蔽効果を有している上に、柔軟性が保たれており且つ軽量である。 Regardless of any of the above radiation shielding flexible materials, the lead-containing layer having lead powder is laid so as to be wholly or partially integrated with the base fabric, and the lead powder fits into holes or voids in the base fabric. Since it is scattered so as to be trapped, it has a radiation shielding effect, and is flexible and lightweight.
以下、添付図面を参照しながら、本考案の具体的な実施形態を詳細に説明する。 Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.
（第１の実施形態）
図１〜図３は、本考案に係る放射線遮蔽用柔軟性素材の第１の実施形態を概略的に示した図であり、本実施形態における放射線遮蔽用柔軟性素材は、基布１１と、鉛含有層２０とからなっている。
(First embodiment)
1 to 3 are diagrams schematically showing a first embodiment of a radiation shielding flexible material according to the present invention, and the radiation shielding flexible material according to the present embodiment includes a base fabric 11, and FIGS. It consists of a lead-containing layer 20.
基布１１は、可撓性を有すると共にその内外に多数の孔や空隙１１１が存在している。基布１１を構成する材料としては、可撓性があり且つ多孔構造を有するもの、例えば不織布、繊維材料、樹脂材料、パルプ由来の材料あるいはこれらを組み合わせた混合材料を用いることができる。また、基布１１の厚みも本考案においては制限はなく、所望の放射線遮蔽効果が備わるように調整することができるが、２ｍｍ以上の厚みを有するように形成するとよい。 The base fabric 11 has flexibility and has a large number of holes and voids 111 inside and outside thereof. As a material constituting the base fabric 11, a flexible material having a porous structure, for example, a nonwoven fabric, a fiber material, a resin material, a pulp-derived material, or a mixed material combining these materials can be used. Further, the thickness of the base fabric 11 is not limited in the present invention and can be adjusted so as to provide a desired radiation shielding effect, but it may be formed to have a thickness of 2 mm or more.
鉛含有層２０は、主に鉛粉２１と粘着剤２２とから混合されてなっており、鉛粉２１が散在して（図２参照）基布１１の上述した孔や空隙１１１に嵌まり込むように、基布１１の表面側に敷設されている。なお、鉛粉２１は、主に鉛金属を例えば研磨することで所定の粒径にした粉末であり、粘着剤２２は、粘着性を有する液体であり、鉛粉２１と基布１１とを結合する媒体となるものである。 The lead-containing layer 20 is mainly composed of a lead powder 21 and an adhesive 22, and the lead powder 21 is scattered (see FIG. 2) and fits into the above-described holes and voids 111 of the base fabric 11. Thus, it is laid on the surface side of the base fabric 11. In addition, the lead powder 21 is a powder having a predetermined particle size mainly by polishing lead metal, for example, and the adhesive 22 is a liquid having adhesiveness, and the lead powder 21 and the base fabric 11 are combined. It becomes a medium to do.
本実施形態における、基布１１への鉛含有層２０の上記敷設態様を具体的に説明すると、鉛含有層２０は、図４〜図６に示されているようなローラープレスを用いた押圧加工により、その含有する鉛粉２１および粘着剤２２のほぼ全てが、基布１１の表面の孔から内部の空隙に嵌まり込むようにして、基布１１の表面近くにある内部構造と密接に結合している。即ち、鉛含有層２０は、基布１１に染み入るようにこれと一体になっている。 If the said installation aspect of the lead-containing layer 20 to the base fabric 11 in this embodiment is demonstrated concretely, the lead-containing layer 20 will be a press process using the roller press as shown in FIGS. Accordingly, almost all of the lead powder 21 and the adhesive 22 contained therein are closely coupled to the internal structure near the surface of the base fabric 11 so that the lead powder 21 and the adhesive 22 are fitted into the internal space from the holes on the surface of the base fabric 11. Yes. That is, the lead-containing layer 20 is integrated with the base fabric 11 so as to penetrate.
なお、上記ローラープレスによる押圧加工には、一般の印刷機を用いることができる。例えば、図４に示されているような上下１組のローラー１を数組有する印刷機を用いる場合、鉛含有層２０となる材料２０ａを塗料としてローラー１に予め塗布しておく。その後、基布１１をローラー１に通すと、鉛含有層２０となる材料２０ａが基布１１の表面に押圧されることにより、該材料２０ａ中の鉛粉２１が基布１１の孔や空隙１１１に粘着剤２２と共に入り込むと共に、ローラー１の押圧により基布１１の孔や空隙１１１が押し潰されるように狭まり、鉛含有層２０が基布１１と密接に結合して一体となるように形成される（図５参照）。 In addition, a general printing machine can be used for the press process by the said roller press. For example, when using a printing machine having several pairs of upper and lower rollers 1 as shown in FIG. 4, the material 20 a to be the lead-containing layer 20 is applied to the roller 1 in advance as a paint. Thereafter, when the base fabric 11 is passed through the roller 1, the material 20 a that becomes the lead-containing layer 20 is pressed against the surface of the base fabric 11, so that the lead powder 21 in the material 20 a becomes holes or voids 111 in the base fabric 11. It is formed so that the hole and the gap 111 of the base cloth 11 are crushed by the pressure of the roller 1 and the lead-containing layer 20 is intimately coupled with the base cloth 11 together. (See FIG. 5).
また、図４に示されているように、基布１１は数組のローラー１に通されるが、２組目以下のローラー１を通ると、上述のように鉛含有層２０となる材料２０ａが基布１１の表面に繰り返し押圧されることにより、基布１１の特に表面付近により多くの鉛粉２１が嵌まり込むようになる（図６参照）。よって、基布１１における鉛粉２１の密度は、押圧加工の回数（ローラー１の組数）により調節することができ、鉛粉２１の密度は放射線遮蔽効果に対応するので、本考案に係る放射線遮蔽用柔軟性素材は、製造工程の簡易な変更によりそれぞれ異なるレベルの放射線遮蔽効果を備えることができる。 As shown in FIG. 4, the base fabric 11 is passed through several sets of rollers 1, but when passing through the second and subsequent sets of rollers 1, the material 20 a that becomes the lead-containing layer 20 as described above. Is repeatedly pressed against the surface of the base fabric 11, so that more lead powder 21 is fitted into the base fabric 11 particularly near the surface (see FIG. 6). Therefore, the density of the lead powder 21 in the base fabric 11 can be adjusted by the number of pressing processes (the number of sets of rollers 1), and the density of the lead powder 21 corresponds to the radiation shielding effect. Shielding flexible materials can have different levels of radiation shielding effects by simple changes in the manufacturing process.
なお、本考案において、鉛含有層２０の基布１１への敷設方法は上述したローラープレスによる押圧加工に限らず、他の方法、例えば、浸染、コーティング、一体射出成形などにより敷設しても構わない。 In the present invention, the method of laying the lead-containing layer 20 on the base fabric 11 is not limited to the pressing process using the roller press described above, but may be laid by other methods such as dip dyeing, coating, integral injection molding, and the like. Absent.
例えばコーティングにより敷設した場合には、鉛含有層２０は、基布１１の表面付近に位置する鉛粉２１および粘着剤２２のみが、基布１１の表面における孔や空隙１１１に嵌まり込むように、基布１１の表面と密に接するようになる。即ちこの場合、鉛含有層２０と基布１１とは全体が一体にはならず、それらの部分同士だけが重なって一体になる。 For example, when laid by coating, the lead-containing layer 20 is such that only the lead powder 21 and the adhesive 22 located in the vicinity of the surface of the base fabric 11 are fitted into the holes or voids 111 on the surface of the base fabric 11. In close contact with the surface of the base fabric 11. That is, in this case, the lead-containing layer 20 and the base fabric 11 are not integrated as a whole, but only those portions are overlapped and integrated.
本考案は、鉛粉２１を有する鉛含有層２０が、上述したように基布１１と全体的にあるいは部分的に一体となるように敷設されており、鉛粉２１が基布１１における孔や空隙１１１に嵌まり込むように散在しているので、基布１１の柔軟性が損なわれていない上に、従来技術である鉛塊や鉛片を基布１１に固定した放射線遮蔽用素材と比べて遥かに軽量である。 In the present invention, as described above, the lead-containing layer 20 having the lead powder 21 is laid so as to be wholly or partially integrated with the base cloth 11, and the lead powder 21 has holes or holes in the base cloth 11. Since it is scattered so as to fit in the gaps 111, the flexibility of the base fabric 11 is not impaired, and compared with a radiation shielding material in which lead blocks and lead pieces are fixed to the base fabric 11 as in the prior art. Far lighter.
つまり、本考案に係る放射線遮蔽用柔軟性素材は、例えば衣類、包装袋、食品容器、乗り物など、放射線の遮蔽が必要なあらゆる場に応用することができる。特に、本考案に係る放射線遮蔽用柔軟性素材によれば、軽量化および柔軟性の保持が果たされているので、日常的に着用できる衣類の素材として用いられることができる。 That is, the flexible material for shielding radiation according to the present invention can be applied to any place where radiation shielding is required, such as clothing, packaging bags, food containers, and vehicles. In particular, according to the flexible material for shielding radiation according to the present invention, the weight reduction and the maintenance of flexibility are achieved, so that it can be used as a clothing material that can be worn on a daily basis.
（第２の実施形態）
図７には本考案に係る放射線遮蔽用柔軟性素材の第２の実施形態が示されている。基布３１は上記第１の実施形態のように鉛含有層３０が一体となるように敷設されたものであるが、本実施形態では、この基布３１の一側表面に、印刷により更なる鉛含有層３０が積層されるように（図示では２層）設けられている。これにより第２の実施形態では放射線遮蔽効果が更に向上されている。
(Second Embodiment)
FIG. 7 shows a second embodiment of the flexible material for shielding radiation according to the present invention. The base fabric 31 is laid such that the lead-containing layer 30 is integrated as in the first embodiment. In the present embodiment, the base fabric 31 is further printed on one side surface of the base fabric 31 by printing. The lead-containing layer 30 is provided so as to be laminated (two layers in the drawing). Thereby, the radiation shielding effect is further improved in the second embodiment.
（第３の実施形態）
図８には本考案に係る放射線遮蔽用柔軟性素材の第３の実施形態が示されている。第２の実施形態とほぼ同じであるが、違いは、第２の実施形態では基布３１の一側表面に鉛含有層３０を積層したが、本実施形態では基布４１の両側表面にそれぞれ更に鉛含有層４０が基布４１と積層するように設けられている。
(Third embodiment)
FIG. 8 shows a third embodiment of the radiation shielding flexible material according to the present invention. Although it is almost the same as the second embodiment, the difference is that the lead-containing layer 30 is laminated on one side surface of the base fabric 31 in the second embodiment. Further, a lead-containing layer 40 is provided so as to be laminated with the base cloth 41.
（第４の実施形態）
図９には本考案に係る放射線遮蔽用柔軟性素材の第４の実施形態が示されている。基布５１は上記第１の実施形態のように鉛含有層２０が一体となるように敷設されたものであるが、本実施形態ではこの基布５１が数枚（図示では３枚）重なって粘着結合されている。つまり、本実施形態に係る放射線遮蔽用柔軟性素材は第１の実施形態における放射線遮蔽用柔軟性素材が数枚重なってなったものである。これにより該素材の厚みが増すことで放射線遮蔽効果が更に向上されている。
(Fourth embodiment)
FIG. 9 shows a fourth embodiment of the flexible material for shielding radiation according to the present invention. The base fabric 51 is laid such that the lead-containing layer 20 is integrated as in the first embodiment, but in this embodiment, several base fabrics 51 (three in the figure) overlap. Adhesive bond. That is, the radiation shielding flexible material according to the present embodiment is formed by overlapping the radiation shielding flexible material according to the first embodiment. Thereby, the radiation shielding effect is further improved by increasing the thickness of the material.
（第５の実施形態）
図１０は本考案に係る放射線遮蔽用柔軟性素材の第５の実施形態が示されている。基布４１およびその両側表面に設けられている鉛含有層４０は第３の実施形態によるものと同じだが、本実施形態では更に、両方の鉛含有層４０の各表面がカバー層６０により覆われている。即ち本実施形態における放射線遮蔽用柔軟性素材は、第３の実施形態における放射線遮蔽用柔軟性素材が更にカバー層６０に包まれてなったものである。
(Fifth embodiment)
FIG. 10 shows a fifth embodiment of the radiation shielding flexible material according to the present invention. The base cloth 41 and the lead-containing layer 40 provided on both side surfaces thereof are the same as those according to the third embodiment. However, in this embodiment, the surfaces of both lead-containing layers 40 are further covered with the cover layer 60. ing. That is, the radiation shielding flexible material in the present embodiment is obtained by further wrapping the radiation shielding flexible material in the third embodiment in the cover layer 60.
カバー層６０は、例えば一枚をＰＥＴで、もう一枚をＰＶＣやＰＥ、ナイロンなどの樹脂で構成し、それら二枚を放射線遮蔽用柔軟性素材を包み込むように貼り合わせてから、例えば超音波溶着法を用いて溶着することで形成できる。 The cover layer 60 is composed of, for example, one sheet of PET and the other sheet of resin such as PVC, PE, or nylon, and the two sheets are bonded together so as to wrap the radiation shielding flexible material. It can be formed by welding using a welding method.
カバー層６０に包まれることで、本実施形態における放射線遮蔽用柔軟性素材は、鉛含有層４０から鉛粉が脱落することを防ぐことができる。よって、本実施形態に係る放射線遮蔽用柔軟性素材は、例えば一般の包装袋の材料に適している。 By wrapping in the cover layer 60, the radiation shielding flexible material in the present embodiment can prevent the lead powder from dropping off from the lead-containing layer 40. Therefore, the flexible material for radiation shielding according to the present embodiment is suitable for a general packaging bag material, for example.
なお、更なる変化例として、カバー層６０は基布１１を直接包むように設けられてもよい。即ち、上記第１、第２、第４の実施形態における放射線遮蔽用柔軟性素材も、その外表がカバー層６０に包まれるようにしてなってもよい。 As a further variation, the cover layer 60 may be provided so as to directly wrap the base fabric 11. That is, the radiation shielding flexible material in the first, second, and fourth embodiments may be configured such that its outer surface is wrapped in the cover layer 60.
