Description

本発明は、補強方法に関する。
The present invention relates to a reinforcement 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 are sheet-like reinforcing materials that are used by being attached to steel plates. For example, Patent Document 1 discloses a sheet-like reinforcing material in which a layer of an expandable composition and a layer of glass cloth or the like are laminated. It is

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 to reinforce the steel plate of the automobile body by attaching such a reinforcing material to the steel plate of the automobile body, and foaming and hardening the layer of the foamable composition by the dry heat of the electrodeposition coating. ing.

特開2005-41210号公報JP-A-2005-41210

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, high-temperature heat must be applied to the whole of the reinforcing material attached to the steel plate of the vehicle body, which is the adherend. Since it is difficult to apply it to the adherend, it has low versatility. Further, when the reinforcing material is attached to the adherend, the reinforcing material may interfere with the coating.

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。 In addition, after application, the layer of the foamable composition is not completely fixed to the adherend until heat is applied in the electrodeposition coating, and during these steps, for example, vibration occurs during transportation. If the force is applied, the reinforcing member may be displaced, and as a result, there is a possibility that the desired portion cannot 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方法を提供することを目的とする。

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、前記補強材を誘電加熱し、前記被着体に前記補強材を貼付する。 The reinforcing method of the present invention for achieving the above object is to dispose the reinforcing material so that the base material layer is in contact with a member that is an adherend, dielectrically heat the reinforcing material, and The stiffener 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 high frequencies, the reinforcing material can be heated independently of the adherend. It is not necessary to heat the whole while being attached to the body. Therefore, the adherend is not easily affected by heat, and the invention having the above configuration can be applied not only to metal adherends but also to resin adherends with lower heat resistance compared to metal adherends, and has versatility. expensive.

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 apply the coating while the reinforcing material is attached to the adherend in order to utilize the drying heat during coating. , which prevents the coating from being impeded 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 arranged at a desired position of the adherend, the reinforcing material can be immediately fixed to the site using the heat generation of the heat generating particles. Therefore, the reinforcing material is less likely to be misaligned, and the 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. Note that 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 consisting of a base material layer 110, and heat-generating particles 120 are contained therein.

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 layer 110 is made of resin. The resin forming the base layer 110 preferably has good strength, and examples thereof include polypropylene (PP) and acrylonitrile-butadiene-styrene copolymer (ABS). Not limited. The thickness of the base material layer 110 can be set in consideration of, for example, the strength and arrangement space in the adherend, and is about several millimeters to several centimeters, 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。 Heat-generating particles 120 have the property of generating heat upon receiving high-frequency waves. The material for forming the heat generating particles 120 is not particularly limited as long as it has such properties, but examples include zinc oxide, silicon carbide, titanium oxide, barium titanate, barium zirconate titanate, lead titanate, potassium niobate, Inorganic substances having water of crystallization such as hydrated aluminum silicate, hydrated aluminosilicates of alkali metals or alkaline earth metals, etc., may be used singly or in combination of two or more. Zinc, 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, first, a reinforcing material 100 is placed on a 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 the 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 a coating film 12 is formed on the surface of a base material 11 made of metal. 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 painting is applied before the stiffener 100 is placed 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。 Although the member 10 has a curved shape in this embodiment, it is not limited thereto and may have a flat shape. A reinforcing material 100 is placed at a desired location on the member 10 . In this embodiment, the reinforcing member 100 is arranged on the curved portion of the member 10, but is not limited to this, and may be arranged on 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 this embodiment, the reinforcing member 100 deforms 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 material 100 is not attached to the member 10 only by being pressed against the member 10 , the reinforcing material 100 is fixed in place after being placed 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 member 100 is irradiated with the high frequency 1C, and the base material layer 110 is fixed to the member 10 using the heat generation of the heat generating particles 120 . Thus, 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。 A high frequency 1C is generated between the electrodes 1A, 1B arranged toward the stiffener 100. FIG. 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 on the same surface of the reinforcing material 100 with a space therebetween, 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 member 100. For example, the electrodes 1A and 1B may be arranged so as to sandwich the reinforcing member 100 together with the member 10 from the thickness direction. However, as compared to the case of sandwiching from the thickness direction in this way, it is preferable to dispose the electrodes 1A and 1B on the same surface of the reinforcing member 100 as shown in FIG.

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 has a frequency of, for example, 1 to 100 MHz, but is not limited to this frequency. The heat generating particles 120 generate heat by dielectric heating when irradiated with the high frequency 1C, and the heat generation stops when the high frequency 1C is stopped. For example, when the heat generating particles 120 generate heat, the base layer 110 formed of a thermoplastic resin such as polypropylene (PP) is softened by the heat and conforms to the member 10. When the heat generating particles 120 stop generating heat, the base layer 110 110 adheres to the member 10 while hardening.

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 material for forming the base material layer 110 is not limited to this form, and the material forming the base material layer 110 may be a thermosetting resin. 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。 Moreover, the base layer 110 may contain a foaming agent. The blowing agent is not particularly limited, but for example, organic blowing agents such as azobisisobutyronitrile, azodicarbonamide and benzenesulfonyl hydrazide; One or more 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 the foaming agent, it expands and increases in thickness as the heat generating particles 120 generate heat. This is because the foaming agent contained in the base material layer 110 is foamed by 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 irradiation time of high frequency 1C is not particularly limited, but is, for example, several seconds. Therefore, the fixing 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. The electrodes 1A and 1B are separated from the reinforcing material 100 after the irradiation of the high frequency 1C is completed. Through the above operations, the member 10 is reinforced at desired locations, and a member with a reinforcing member in which the reinforcing member 100 is attached to the member 10 is manufactured.

次に、本実施形態の作用効果を述べる。 Next, the effect of this embodiment is 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 this embodiment, the heating particles 120 included in the reinforcing material 100 generate heat by receiving the high frequency 1C, so 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 to the case where the member 10 is made of metal as in the present embodiment, but also to the case where the member 10 is made of resin having low heat resistance compared to that, and has high versatility. . For example, this embodiment can also be applied to resin bumpers and 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 this embodiment, since the reinforcing member 100 can be heated independently of the member 10, in order to divert the drying heat at the time of painting, the reinforcing member 100 is attached to the base material 11 of the member 10. It does not need to be painted, so that the painting can be prevented from being hindered by the reinforcing member 100. - 特許庁Painting is applied to prevent corrosion and improve design, and if the painting is hindered, those functions will be impaired. It fulfills its original role well.

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 placed at a desired location on the member 10, the reinforcing member 100 can be immediately fixed to that location using the heat generation of the heat generating particles 120. FIG. Therefore, the reinforcing member 100 is less likely to be misaligned, and the 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。 Moreover, if the base material layer 110 contains a foaming agent, the thickness and density of the base material layer 110 can be changed by the foaming of the foaming agent. Further, if the base material layer 110 contains a foaming agent, it is possible to make the base material layer 110 more likely to absorb sound by foaming the foaming agent. Quietness can be improved when noise is a problem at a door or 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 this embodiment, the reinforcing material 100 has a single layer structure consisting of the base material layer 110 and does not have other layers other than the base material layer 110 . Therefore, when the reinforcing material 100 is arranged on the member 10, the deformation of the base material layer 110 is not hindered by other layers, and the reinforcing material 100 follows the shape of the member 10 well to support 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 embodiments described above, but can be variously modified 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 a single-layer structure consisting of a substrate layer as in the above embodiment, and may have other layers in addition to the substrate 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, a reinforcing member 200 shown in FIG. 5 has a reinforcing layer 201 laminated on the base layer 110 in addition to the base layer 110 of the above embodiment. The base material layer 110 and the reinforcing layer 201 are united so as not to be separated.

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, strength greater than or equal to that of the base layer 110 . In addition, the reinforcing layer 201 is deformable to some extent according to the base layer 110 . The reinforcement layer 201 is, for example, glass cloth, carbon fiber, or the like, but is not limited to these.

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 member 200 of the modified example is used in the same manner as in the above-described embodiment, is arranged so that the base material layer 110 is in contact with the member 10 which is the adherend, and is irradiated with the high frequency 1C. affixed.

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。 Like the reinforcing member 100 of the above embodiment, a single-layer structure that does not have a layer other than the base layer 110 is easier to deform and has excellent shape followability to the adherend. By having the reinforcing layer 201 on the inside, 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。 Both the reinforcing member 100 of the above embodiment and the reinforcing member 200 of the modified example have a sheet shape, but the size and shape of the reinforcing member of the present invention are not particularly limited. The shape and size can be appropriately designed accordingly.

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, application of the present invention is not limited to the automobile field, and the present invention may be applied to fields other than automobiles.
