Description
本発明は、補強材、補強材付部材、および補強方法に関する。 The present invention relates to a reinforcing material, a member with a reinforcing material, and a reinforcing method.
従来、鋼板に貼付して使用されるシート状の補強材があり、例えば特許文献１では、発泡性組成物の層と、ガラスクロス等の層とが積層されてなるシート状の補強材が開示されている。 Conventionally, there is a sheet-shaped reinforcing material that is used by being attached to a steel plate. For example, Patent Document 1 discloses a sheet-shaped reinforcing material in which a layer of a foamable composition and a layer such as glass cloth are laminated. Has been done.
特許文献１は、そのような補強材を自動車の車体鋼板に貼付し、電着塗装時の乾燥熱で発泡性組成物の層を発泡および硬化させることによって、車体鋼板を補強することを提案している。 Patent Document 1 proposes that such a reinforcing material is attached to an automobile body steel sheet, and the body steel sheet is reinforced by foaming and curing a layer of a foamable composition with the drying heat during electrodeposition coating. ing.
しかしながら、上記従来技術のやり方は、被着体である車体鋼板に補強材を貼付した状態でそれら全体に高温の熱を加えなければならず、車体鋼板に比べて耐熱性の低い樹脂によって形成された被着体への適用は困難であることから、汎用性が低い。また、補強材が被着体に貼付された状態では、補強材が塗装の妨げになる虞がある。 However, in the method of the above-mentioned prior art, it is necessary to apply high-temperature heat to all of the body steel sheets to which the reinforcing material is attached, and the heat resistance is lower than that of the body steel sheets. Since it is difficult to apply it to an adherend, its versatility is low. Further, when the reinforcing material is attached to the adherend, the reinforcing material may interfere with painting.
また、貼付後、電着塗装において熱が加えられるまでの間は、発泡性組成物の層が完全には被着体に固着しておらず、それらの工程間で例えば搬送等にともなって振動が加わると、補強材が位置ズレし、その結果、所望の箇所を適切に補強できない虞がある。 Further, after the application, the layer of the foamable composition is not completely adhered to the adherend until heat is applied in the electrodeposition coating, and vibrations occur between these processes due to, for example, transportation. If is added, the reinforcing material may be misaligned, and as a result, the desired portion may not be properly reinforced.
本発明は、それらの課題に鑑みてなされ、汎用性が高く、塗装の妨げになり難いとともに、所望の箇所を適切に補強しうる補強材、補強材付部材、および補強方法を提供することを目的とする。 The present invention has been made in view of these problems, and provides a reinforcing material, a member with a reinforcing material, and a reinforcing method which are highly versatile, do not easily interfere with painting, and can appropriately reinforce a desired portion. The purpose.
上記目的を達成するための本発明の補強材は、樹脂によって形成された基材層を有し、当該基材層内に、高周波によって発熱する発熱粒子を含む。 The reinforcing material of the present invention for achieving the above object has a base material layer formed of a resin, and contains heat-generating particles that generate heat due to high frequencies in the base material layer.
上記目的を達成するための本発明の補強材付部材は、前記補強材と、前記補強材が貼付された部材と、を有する。 The member with a reinforcing material of the present invention for achieving the above object includes the reinforcing material and a member to which the reinforcing material is attached.
上記目的を達成するための本発明の補強方法は、前記補強材を、被着体である部材に対して前記基材層が接するように配置し、前記補強材に高周波を照射し、前記被着体に前記補強材を貼付する。 In the reinforcing method of the present invention for achieving the above object, the reinforcing material is arranged so that the base material layer is in contact with a member which is an adherend, and the reinforcing material is irradiated with a high frequency to be covered. The reinforcing material is attached to the body.
上記構成を有する発明によれば、補強材に含まれる発熱粒子が高周波を受けて発熱するため、補強材を被着体と独立して加熱可能であり、上記従来技術のように補強材を被着体に貼付した状態でそれら全体を加熱する必要がない。従って、被着体が熱の影響を受け難く、上記構成を有する発明は、金属製の被着体に加え、それに比べて耐熱性の低い樹脂製の被着体にも適用でき、汎用性が高い。 According to the invention having the above configuration, since the heat-generating particles contained in the reinforcing material generate heat by receiving a high frequency, the reinforcing material can be heated independently of the adherend, and the reinforcing material is covered as in the above-mentioned prior art. It is not necessary to heat them all while they are attached to the body. Therefore, the invention in which the adherend is not easily affected by heat and has the above configuration can be applied not only to the metal adherend but also to the resin adherend having lower heat resistance than the metal adherend, and is versatile. high.
上記構成を有する発明によれば、補強材を被着体と独立して加熱可能であることから、塗装時の乾燥熱を流用するために被着体に補強材を貼付した状態で塗装する必要がなく、このため、塗装が補強材によって妨げられるのを防止できる。 According to the invention having the above configuration, since the reinforcing material can be heated independently of the adherend, it is necessary to paint with the reinforcing material attached to the adherend in order to divert the drying heat at the time of painting. Therefore, it is possible to prevent the coating from being hindered by the reinforcing material.
上記構成を有する発明によれば、補強材は、被着体の所望の箇所に配置されると、発熱粒子の発熱を利用して、その場に直ぐに固着可能である。このため、補強材が位置ズレし難く、被着体の所望の箇所を適切に補強できる。 According to the invention having the above configuration, when the reinforcing material is placed at a desired position on the adherend, it can be immediately fixed to the place by utilizing the heat generated by the heat-generating particles. Therefore, the reinforcing material is unlikely to be displaced, and a desired portion of the adherend can be appropriately reinforced.
以下、添付した図面を参照しながら、本発明の実施形態を説明する。なお、図面の寸法比率は、説明の都合上誇張されており、実際の比率とは異なる。 Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. The dimensional ratios in the drawings are exaggerated for convenience of explanation and differ from the actual ratios.
図１に示すように、実施形態の補強材１００は、基材層１１０からなる単層構造を有し、その内部に発熱粒子１２０を含む。 As shown in FIG. 1, the reinforcing material 100 of the embodiment has a single-layer structure composed of a base material layer 110, and includes heat-generating particles 120 inside.
基材層１１０は、樹脂によって形成されている。基材層１１０を形成する樹脂は、良好な強度を有するがことが好ましく、そのような例として、ポリプロピレン（ＰＰ）、アクリロニトリル−ブタジエン−スチレン共重合体（ＡＢＳ）等が挙げられるが、これらに限定されない。基材層１１０の厚みは、例えば強度や被着体における配置スペース等を考慮して設定でき、数ｍｍ〜数ｃｍ程度であるが、特に限定されない。 The base material layer 110 is made of resin. The resin forming the base material layer 110 preferably has good strength, and examples thereof include polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), and the like. Not limited. The thickness of the base material layer 110 can be set in consideration of, for example, the strength and the arrangement space in the adherend, and is about several mm to several cm, but is not particularly limited.
発熱粒子１２０は、高周波を受けて発熱する性質を有する。このような性質を有すれば、発熱粒子１２０の形成材料は特に限定されないが、例えば、酸化亜鉛、炭化ケイ素、酸化チタン、チタン酸バリウム、チタン酸ジルコン酸バリウム、チタン酸鉛、ニオブ酸カリウム、水和ケイ酸アルミニウム、アルカリ金属またはアルカリ土類金属の水和アルミノケイ酸塩等の結晶水を有する無機物質等の一種単独または二種以上の組み合わせであり、発熱性の観点から、好ましくは、酸化亜鉛、炭化ケイ素である。 The heat generating particles 120 have a property of receiving high frequency and generating heat. The material for forming the heat-generating particles 120 is not particularly limited as long as it has such properties, but for example, zinc oxide, silicon carbide, titanium oxide, barium titanate, barium disilicate, lead titanate, potassium niobate, etc. It is one kind or a combination of two or more kinds of inorganic substances having crystalline water such as hydrated aluminum silicate, alkali metal or alkaline earth metal hydrated aluminosilicate, and is preferably oxidized from the viewpoint of heat generation. Zinc and silicon carbide.
次に、補強材１００を使用した補強方法を述べる。 Next, a reinforcing method using the reinforcing material 100 will be described.
図２に示すように、実施形態の補強方法では、まず、補強材１００が、被着体である部材１０に配置される。部材１０は、特に限定されないが、例えば、自動車の車体を構成するドアやリヤフェンダー等の部材である。 As shown in FIG. 2, in the reinforcing method of the embodiment, the reinforcing member 100 is first arranged on the member 10 which is an adherend. The member 10 is not particularly limited, but is, for example, a member such as a door or a rear fender that constitutes a vehicle body of an automobile.
部材１０は、金属製の基材１１の表面に塗膜１２が形成された構成を有する。基材１１は、例えば鋼板である。塗膜１２は、例えば電着塗装によって形成されるが、これに限定されず、他の塗装方法によって形成されてもよい。塗装は、部材１０に補強材１００が配置される前に施される。 The member 10 has a structure in which the coating film 12 is formed on the surface of the metal base material 11. The base material 11 is, for example, a steel plate. The coating film 12 is formed by, for example, electrodeposition coating, but is not limited to this, and may be formed by other coating methods. The coating is applied before the reinforcing member 100 is arranged on the member 10.
部材１０は、本実施形態では湾曲した形状を有するが、これに限定されず、平坦な形状を有してもよい。部材１０における所望の箇所に、補強材１００は配置される。本実施形態では、補強材１００は、部材１０の湾曲部に配置されるが、これに限定されず、平坦な箇所に配置されてもよい。補強材１００は、基材層１１０が可撓性を有するため、部材１０に押し当てられると、その形状に合わせて変形する。本実施形態では、補強材１００は、部材１０の湾曲部に沿うように変形する。 The member 10 has a curved shape in the present embodiment, but is not limited to this, and may have a flat shape. The reinforcing member 100 is arranged at a desired position on the member 10. In the present embodiment, the reinforcing member 100 is arranged at the curved portion of the member 10, but is not limited to this, and may be arranged at a flat portion. Since the base material layer 110 has flexibility, the reinforcing material 100 deforms according to its shape when pressed against the member 10. In the present embodiment, the reinforcing member 100 is deformed along the curved portion of the member 10.
補強材１００は、部材１０に押し当てられて配置されただけでは、部材１０に貼り付いていないため、部材１０への配置に続けて、その場に固着される。 Since the reinforcing member 100 is not attached to the member 10 only by being pressed against the member 10 and arranged, the reinforcing member 100 is fixed in place following the arrangement on the member 10.
具体的に、図３に示すように、補強材１００に高周波１Ｃが照射され、発熱粒子１２０の発熱を利用して、基材層１１０が部材１０に固着される。こうして、補強材１００は、部材１０に貼付される。 Specifically, as shown in FIG. 3, the reinforcing material 100 is irradiated with the high frequency 1C, and the base material layer 110 is fixed to the member 10 by utilizing the heat generated by the heat generating particles 120. In this way, the reinforcing material 100 is attached to the member 10.
高周波１Ｃは、補強材１００に向けて配置された電極１Ａ、１Ｂの間に生じる。電極１Ａ、１Ｂは、それらに高周波の電圧を印加する高周波発生装置（不図示）と電気的に接続している。 The high frequency 1C is generated between the electrodes 1A and 1B arranged toward the reinforcing member 100. The electrodes 1A and 1B are electrically connected to a high frequency generator (not shown) that applies a high frequency voltage to them.
本実施形態では、電極１Ａ、１Ｂは、補強材１００の同一面に対向し離間して配置されているが、このような配置に限定されない。電極１Ａ、１Ｂは、高周波１Ｃが補強材１００に作用するように配置されればよく、例えば、補強材１００を部材１０とともに厚み方向から挟むように配置されてもよい。ただ、このように厚み方向から挟む場合に比べ、図３のように補強材１００の同一面に電極１Ａ、１Ｂが配置された方が、高周波１Ｃがより補強材１００に作用し易く、好ましい。 In the present embodiment, the electrodes 1A and 1B are arranged so as to face the same surface of the reinforcing member 100 and are separated from each other, but the arrangement is not limited to this. The electrodes 1A and 1B may be arranged so that the high frequency 1C acts on the reinforcing material 100, and for example, the reinforcing material 100 may be arranged so as to sandwich the reinforcing material 100 together with the member 10 from the thickness direction. However, it is preferable that the electrodes 1A and 1B are arranged on the same surface of the reinforcing material 100 as shown in FIG. 3, because the high frequency 1C is more likely to act on the reinforcing material 100 than in the case of sandwiching from the thickness direction.
高周波１Ｃは交番電界であり、周波数が例えば１〜１００ＭＨｚであるが、この周波数に限定されない。発熱粒子１２０は、高周波１Ｃが照射されると誘電加熱によって発熱し、また、高周波１Ｃの停止とともに発熱が止む。例えばポリプロピレン（ＰＰ）等の熱可塑性樹脂によって形成された基材層１１０は、発熱粒子１２０が発熱すると、その熱によって軟化して部材１０になじみ、発熱粒子１２０の発熱が止むと、基材層１１０は硬化しつつ部材１０に固着する。 The high frequency 1C is an alternating electric field, and the frequency is, for example, 1 to 100 MHz, but the frequency is not limited to this frequency. When the high frequency 1C is irradiated, the heat generating particles 120 generate heat by dielectric heating, and the heat generation stops when the high frequency 1C stops. For example, the base material layer 110 formed of a thermoplastic resin such as polypropylene (PP) softens due to the heat generated by the heat-generating particles 120 and becomes familiar with the member 10, and when the heat generation of the heat-generating particles 120 stops, the base material layer 110 110 is fixed to the member 10 while being cured.
ただしこの形態に限定されず、基材層１１０の形成材料は、熱硬化性樹脂であってもよく、この場合、基材層１１０は、発熱粒子１２０の発熱によって、硬化するとともに部材１０に固着する。 However, the present invention is not limited to this form, and the material for forming the base material layer 110 may be a thermosetting resin. In this case, the base material layer 110 is cured by the heat generated by the heat generating particles 120 and is fixed to the member 10. To do.
また、基材層１１０は、発泡剤を含んでもよい。発泡剤としては、特に限定されないが、例えば、アゾビスイソブチロニトリル、アゾジカルボンアマイド、ベンゼンスルフォニルヒドラジド等の有機系発泡剤、重炭酸ナトリウム、炭酸アンモニウム等の無機系発泡剤、加熱膨張性の物質を含むマイクロカプセル等の１種または２種以上を使用できる。 Further, the base material layer 110 may contain a foaming agent. The foaming agent is not particularly limited, and is, for example, an organic foaming agent such as azobisisobutyronitrile, azodicarboxylic amide, benzenesulfonylhydrazide, an inorganic foaming agent such as sodium bicarbonate and ammonium carbonate, and a heat-expandable foaming agent. One or more types such as microcapsules containing substances can be used.
図４に示すように、基材層１１０は、発泡剤を含むと、発熱粒子１２０の発熱にともなって膨張し、厚みを増す。これは、基材層１１０に含まれる発泡剤が、発熱粒子１２０の熱で発泡することに起因する。 As shown in FIG. 4, when the base material layer 110 contains a foaming agent, it expands with the heat generation of the heat generating particles 120 and increases in thickness. This is because the foaming agent contained in the base material layer 110 foams due to the heat of the heat generating particles 120.
高周波１Ｃを照射する時間は、特に限定されないが、例えば数秒である。従って、部材１０への基材層１１０の固着や、発泡剤による基材層１１０の増肉は、短時間で済ませられる。高周波１Ｃの照射終了後、電極１Ａ、１Ｂは、補強材１００から離される。以上の作業によって、部材１０の所望の箇所が補強され、また、部材１０に補強材１００が貼付された補強材付部材が作製される。 The time for irradiating the high frequency 1C is not particularly limited, but is, for example, several seconds. Therefore, the fixation of the base material layer 110 to the member 10 and the thickening of the base material layer 110 by the foaming agent can be completed in a short time. After the irradiation of the high frequency 1C is completed, the electrodes 1A and 1B are separated from the reinforcing material 100. By the above work, a desired portion of the member 10 is reinforced, and a member with a reinforcing material is produced in which the reinforcing material 100 is attached to the member 10.
次に、本実施形態の作用効果を述べる。 Next, the action and effect of this embodiment will be described.
本実施形態によれば、補強材１００に含まれる発熱粒子１２０が、高周波１Ｃを受けて発熱するため、補強材１００を部材１０と独立して加熱可能である。従って、部材１０が熱の影響を受け難く、部材１０が本記実施形態のように金属製の場合だけでなく、それに比べて耐熱性の低い樹脂製の場合にも適用でき、汎用性が高い。例えば、本実施形態は、樹脂製のバンパー等にも適用できる。 According to the present embodiment, since the heat generating particles 120 contained in the reinforcing material 100 generate heat by receiving the high frequency 1C, the reinforcing material 100 can be heated independently of the member 10. Therefore, the member 10 is not easily affected by heat, and can be applied not only when the member 10 is made of metal as in the present embodiment but also when the member 10 is made of resin having lower heat resistance, and is highly versatile. .. For example, the present embodiment can be applied to a resin bumper or the like.
本実施形態によれば、補強材１００を部材１０と独立して加熱可能であることから、塗装時の乾燥熱を流用するために、部材１０の基材１１に補強材１００を貼付した状態で塗装する必要がなく、このため、塗装が補強材１００によって妨げられるのを防止できる。塗装は、腐食防止や意匠性向上のために施され、塗装が妨げられてしまうと、それらの機能が損なわれるが、本実施形態によれば、塗装が妨げられるのが防止されるため、塗装本来の役割が良好に発揮される。 According to the present embodiment, since the reinforcing material 100 can be heated independently of the member 10, the reinforcing material 100 is attached to the base material 11 of the member 10 in order to divert the drying heat at the time of painting. There is no need to paint, which prevents painting from being hindered by the stiffener 100. The painting is applied to prevent corrosion and improve the design, and if the painting is hindered, those functions are impaired. However, according to the present embodiment, the painting is prevented from being hindered, so that the painting is performed. The original role is well demonstrated.
本実施形態によれば、補強材１００は、部材１０の所望の箇所に配置されると、発熱粒子１２０の発熱を利用して、その場に直ぐに固着可能である。このため、補強材１００が位置ズレし難く、部材１０の所望の箇所を適切に補強できる。 According to the present embodiment, when the reinforcing member 100 is arranged at a desired position of the member 10, it can be immediately fixed to the place by utilizing the heat generated by the heat generating particles 120. Therefore, the reinforcing member 100 is unlikely to be displaced, and a desired portion of the member 10 can be appropriately reinforced.
また、基材層１１０が発泡剤を含むようにすれば、発泡剤の発泡によって、基材層１１０の肉厚および密度を変えられるため、補強材１００の強度を好適に調整できる。また、基材層１１０が発泡剤を含むようにすれば、発泡剤を発泡させることによって、基材層１１０に音を吸収させ易くすることが可能であり、このため、例えば部材１０が自動車のドア等で、音が問題となる場合に、静音性を高めることができる。 Further, if the base material layer 110 contains a foaming agent, the wall thickness and density of the base material layer 110 can be changed by foaming the foaming agent, so that the strength of the reinforcing material 100 can be suitably adjusted. Further, if the base material layer 110 contains a foaming agent, it is possible to make it easier for the base material layer 110 to absorb sound by foaming the foaming agent. Therefore, for example, the member 10 is an automobile. Quietness can be improved when sound is a problem at doors and the like.
本実施形態では、補強材１００が、基材層１１０からなる単層構造を有し、基材層１１０以外に他の層を有さない。このため、補強材１００が部材１０に配置される際、基材層１１０の変形が他の層によって妨げられることがなく、補強材１００が、部材１０の形状に良好に追従して部材１０を効果的に補強できる。 In the present embodiment, the reinforcing material 100 has a single-layer structure composed of the base material layer 110, and has no other layers other than the base material layer 110. Therefore, when the reinforcing member 100 is arranged on the member 10, the deformation of the base material layer 110 is not hindered by other layers, and the reinforcing member 100 satisfactorily follows the shape of the member 10 to form the member 10. Can be effectively reinforced.
本発明は、上述した実施形態に限定されるものではなく、特許請求の範囲内で種々改変できる。 The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the claims.
例えば、本発明の補強材は、上記実施形態のように基材層からなる単層構造に限定されず、基材層以外にも他の層を有してもよい。 For example, the reinforcing material of the present invention is not limited to the single-layer structure composed of the base material layer as in the above embodiment, and may have other layers other than the base material layer.
その例として、図５に示す補強材２００は、上記実施形態の基材層１１０に加え、基材層１１０に積層された補強層２０１を有する。基材層１１０と補強層２０１とは、剥離不能に一体となっている。 As an example, the reinforcing material 200 shown in FIG. 5 has a reinforcing layer 201 laminated on the base material layer 110 in addition to the base material layer 110 of the above embodiment. The base material layer 110 and the reinforcing layer 201 are inseparably integrated.
補強層２０１は、強度に優れ、例えば基材層１１０以上の強度を有する。また、補強層２０１は、基材層１１０に合わせてある程度変形可能である。補強層２０１は、例えば、ガラスクロス、カーボンファイバー等であるが、これらに限定されない。 The reinforcing layer 201 has excellent strength, for example, a base material layer 110 or higher. Further, the reinforcing layer 201 is deformable to some extent in accordance with the base material layer 110. The reinforcing layer 201 is, for example, glass cloth, carbon fiber, or the like, but is not limited thereto.
図６に示すように、変形例の補強材２００は、上記実施形態と同様に使用され、被着体である部材１０に対し、基材層１１０が接するように配置され、高周波１Ｃを照射して固着される。 As shown in FIG. 6, the reinforcing material 200 of the modified example is used in the same manner as in the above embodiment, is arranged so that the base material layer 110 is in contact with the member 10 which is an adherend, and is irradiated with high frequency 1C. Is fixed.
上記実施形態の補強材１００のように、基材層１１０以外の層を有さない単層構造を有する方が、変形し易く、被着体への形状追従性に優れるが、変形例のように補強層２０１を有することによって、より強度を高めることができる。 A single-layer structure having no layer other than the base material layer 110, such as the reinforcing material 100 of the above embodiment, is more easily deformed and has excellent shape followability to the adherend, but as in the modified example. By having the reinforcing layer 201 on the surface, the strength can be further increased.
上記実施形態の補強材１００、および変形例の補強材２００は、いずれも、枚葉形状を有するが、本発明の補強材の大きさや形状は特に限定されず、例えば被着体の貼付箇所に対応して形状や大きさを適宜設計可能である。 The reinforcing material 100 of the above embodiment and the reinforcing material 200 of the modified example both have a single-wafer shape, but the size and shape of the reinforcing material of the present invention are not particularly limited, and for example, the reinforcing material of the present invention may be attached to a portion. Correspondingly, the shape and size can be designed as appropriate.
また、本発明の適用は、自動車分野に限定されず、自動車以外の他の分野に本発明が適用されてもよい。 Further, the application of the present invention is not limited to the field of automobiles, and the present invention may be applied to fields other than automobiles.
