Abstract
Description
本発明は、自動車の鋼板に補強性、耐デント性を付与するための鋼板補強シートに関する。 The present invention relates to a steel plate reinforcing sheet for imparting reinforcement and dent resistance to a steel plate of an automobile.
自動車に使用されている鋼板は、主として軽量化のための要請から、厚さが１ｍｍ以下の薄板鋼板が使用されている。薄板鋼板は、製鉄メーカーの研究開発等により、高強度のものが作られているが、自動車のドアアウターパネルなど、大きな面積を有し、外からの応力がかかりやすい場所においては、アウターパネルの裏側に鋼板補強材を貼付する対策が取られることが多い。 Steel sheets used in automobiles are thin steel sheets having a thickness of 1 mm or less mainly due to demands for weight reduction. Thin steel plates are made of high strength by research and development of steel manufacturers, etc., but have a large area, such as automobile door outer panels, where outer panel Measures are often taken to attach a steel plate reinforcement to the back side.
貼付される鋼板補強材としては、ゴム系、エポキシ樹脂系のものをシート状に加工し、粘着性を有するものが多く使用されている。但しシート状の補強材は、貼付のために人手が必要であり、自動車製造ラインにおける自動化の障害となっていた。このため、液状化した鋼板補強組成物が開発されるに至った。 As a steel plate reinforcing material to be affixed, a rubber-based or epoxy-resin-based material is processed into a sheet shape, and many have adhesiveness. However, the sheet-like reinforcing material requires manpower for sticking, which has been an obstacle to automation in the automobile production line. For this reason, the liquefied steel plate reinforcement composition came to be developed.
特開平１０−１６６５０３号には、薄肉鋼板の裏面に補強性樹脂塗布層が形成されている構造体が開示されており、この補強性樹脂塗布層は、エポキシ樹脂系塗料（軟質タイプのみを除く）で形成されている。
また、特開２００２−２２６９９５号には、液状エポキシ樹脂、潜在性硬化剤、アスペクト比（Ｌ／Ｄ）５以上の無機質充填剤を含有し、かつ該無機質充填剤の含有量が２０〜５０重量％であって高粘度粘稠物である塗布型板金補強材組成物が開示されている。
Japanese Patent Application Laid-Open No. 10-166503 discloses a structure in which a reinforcing resin coating layer is formed on the back surface of a thin steel plate. The reinforcing resin coating layer is an epoxy resin paint (excluding only a soft type). ).
Japanese Patent Application Laid-Open No. 2002-226995 contains a liquid epoxy resin, a latent curing agent, an inorganic filler having an aspect ratio (L / D) of 5 or more, and the content of the inorganic filler is 20 to 50 wt. %, A high-viscosity viscous material is disclosed.
しかし、液状、塗料状の鋼板補強材には、加熱硬化する過程において質量が大きく収縮するため、塗布されている鋼板に歪を発生させるという欠点が有り、該問題点を解消してなお、張り剛性、耐デント性に優れた液状、塗料状鋼板補強材は未だ無い。
そこで、従来のシート状の鋼板補強材が有する利点と、液状、塗料状鋼板補強材が有する、施工自動化という利点とを併せ有する鋼板補強シートを開発したものである。
However, liquid and paint-like steel plate reinforcements have the disadvantage of causing distortion in the coated steel plate because the mass shrinks greatly during the heat-curing process. There are no liquid or paint-like steel plate reinforcements with excellent rigidity and dent resistance.
Accordingly, a steel sheet reinforcing sheet has been developed that combines the advantages of a conventional sheet-shaped steel plate reinforcing material with the advantages of construction automation that the liquid and paint-like steel plate reinforcing material has.
ロボット等の機械により、容易に施工を自動化するためには、補強シートを貼着するための粘着力を、従来からの感圧性接着剤に頼らずして、容易に所定の箇所に固定できる能力が必要である。特開平５−１５２１１７号には、樹脂シートの仮止め性能を向上するために、熱硬化性樹脂に磁性粉末と発泡剤を添加した磁性補強シートが開示されている。 Ability to easily fix the adhesive force for sticking the reinforcing sheet to a predetermined place without relying on the conventional pressure-sensitive adhesive in order to easily automate the construction by a machine such as a robot. is required. JP-A-5-152117 discloses a magnetic reinforcing sheet in which a magnetic powder and a foaming agent are added to a thermosetting resin in order to improve the temporary fixing performance of the resin sheet.
しかし、該発明においては、仮止めのための粘着力は依然として熱硬化性樹脂の粘着力に依存しており、磁性粉末による磁力は、樹脂の粘着力を補強するために使われているに過ぎない。このため、該発明においては、従来の鋼板補強シートと同様に、シートの貼着面に離型紙を貼っておくことが必要であり、鋼板に貼りつける直前に、作業員により離型紙を剥してから、シートを貼り付けるという工程が必要である。 However, in this invention, the adhesive force for temporary fixing still depends on the adhesive force of the thermosetting resin, and the magnetic force by the magnetic powder is only used to reinforce the adhesive force of the resin. Absent. For this reason, in this invention, it is necessary to affix the release paper on the sticking surface of the sheet in the same manner as in the conventional steel sheet reinforcing sheet, and the operator releases the release paper immediately before attaching to the steel plate. Therefore, a process of attaching a sheet is necessary.
このような構成である以上、補強シートに磁力を用いているにもかかわらず、工程の自動化には全く寄与することができない。
また、作業員による貼着ミスにより、補強シートの張り直しが必要になった場合には、補強シートと鋼板の界面から剥がすことができずに、補強シートの層間を破壊して剥がしてしまった場合には、そのシートは所定の性能を発揮できない虞が大きいため、廃棄して、新しいシートを貼らざるを得ず、結果としてコストの増加となる。
また、貼着作業の直前に剥がす離型紙は、剥がした後は単なる廃棄物となるため、環境負荷を増大させる。
In addition, when it was necessary to re-stretch the reinforcing sheet due to a mistake in sticking by an operator, it was not possible to peel off from the interface between the reinforcing sheet and the steel sheet, and the layers of the reinforcing sheet were broken and peeled off. In such a case, the sheet has a high possibility of not being able to exhibit the predetermined performance. Therefore, the sheet has to be discarded and a new sheet must be pasted, resulting in an increase in cost.
Moreover, since the release paper to be peeled off immediately before the sticking operation becomes a mere waste after being peeled off, the environmental load is increased.
以上の課題を解決せんと、本発明者らは鋭意研究の結果、補強シートの仮止め貼着作業時に、補強シートに配合する樹脂の粘着力に全く依存することがないため離型紙を含まず、容易に自動機により貼着作業を行なうこと、また鋼板表面の防錆油が残存している状況においても所定位置に容易に貼着することができ、自動車の水洗工程、化成処理工程、電着塗装工程においても所定の位置を保持し続ける補強シートを開発したものである。
その要旨は以下に存する。
As a result of diligent research, the present inventors have not included release paper because they do not depend on the adhesive strength of the resin compounded in the reinforcing sheet at the time of temporarily attaching the reinforcing sheet. It can be easily applied by an automatic machine, and can be easily applied to a specified position even in the situation where rust preventive oil remains on the surface of the steel sheet. This is a development of a reinforcing sheet that keeps a predetermined position in the coating process.
The summary is as follows.
自動車用鋼板補強シートであって、ゴム系合成樹脂に磁気粉末を含有することによって、磁力のみで油面鋼板に貼着し、自動車の水洗工程、化成処理工程、電着塗装工程においても貼着位置を保持し、電着塗装後の加熱炉を通過する時の熱により鋼板に熱融着することを特徴とする磁着鋼板補強シート。
離型紙が貼られていないことを特徴とする、上記磁着鋼板補強シート。
以下に詳細を説明する。
A steel sheet reinforcing sheet for automobiles, which contains magnetic powder in a rubber-based synthetic resin, and is adhered to oil-surfaced steel sheets only by magnetic force, and is also adhered in the water washing process, chemical conversion treatment process, and electrodeposition coating process of automobiles. A magnetically-bonded steel sheet reinforcing sheet that maintains its position and is heat-sealed to a steel sheet by heat when passing through a heating furnace after electrodeposition coating.
The above-mentioned magnetically-adhered steel sheet reinforcing sheet, wherein a release paper is not pasted.
Details will be described below.
本発明になる補強シートに使用するゴム系合成樹脂としては、ポリブタジエンゴム、１，２ポリブタジエンゴム、スチレン−ブタジエンゴム、アクリルニトリル−ブタジエンゴム、ポリイソプレンゴム、クロロプレンゴム、イソブチレン−イソプレンゴムなどの共役ジエン系重合体が挙げられる。特に−OH、−COOH、−NH2、−NCO、−CH＝CH2等の官能基を有するゴムが挙げられる。上記のゴムの中でも、ポリブタジエンゴム、１，２ポリブタジエンゴム、スチレン−ブタジエンゴム、イソブチレン−イソプレンゴムが推奨される。これらのゴム成分は、硫黄を配合することにより、加熱されて加硫硬化反応を起こして強力に硬化し、鋼板に熱融着する。 The rubber-based synthetic resin used in the reinforcing sheet according to the present invention includes conjugates such as polybutadiene rubber, 1,2 polybutadiene rubber, styrene-butadiene rubber, acrylonitrile-butadiene rubber, polyisoprene rubber, chloroprene rubber, and isobutylene-isoprene rubber. A diene polymer is mentioned. Particularly, rubber having a functional group such as —OH, —COOH, —NH 2 , —NCO, —CH═CH 2 and the like can be mentioned. Among the above rubbers, polybutadiene rubber, 1,2 polybutadiene rubber, styrene-butadiene rubber, and isobutylene-isoprene rubber are recommended. By blending sulfur, these rubber components are heated and cause a vulcanization curing reaction to be hardened and thermally fused to the steel sheet.
本発明になる補強シートに使用する充填材としては、磁性粉末を使用することが必須である。磁性粉末としては、フェライト粉末（例えばバリウムまたはストロンチウムフェライト粉末）、希土類コバルト磁石粉末、アルニコ磁石粉末を挙げることができる。また、硫酸バリウム、炭酸カルシウム、タルク、クレー、亜鉛華等を併用することも可能である。上記の磁性粉末の配合量は、貼付する補強シートの重量に応じて、位置を保持するために必要な磁力を発揮する量が必要となる。ゴム系合成樹脂１００質量部に対する磁性粉末の配合割合は、２００〜６００質量部、より好ましくは、２５０〜４５０質量部である。 As the filler used in the reinforcing sheet according to the present invention, it is essential to use magnetic powder. Examples of the magnetic powder include ferrite powder (for example, barium or strontium ferrite powder), rare earth cobalt magnet powder, and alnico magnet powder. It is also possible to use barium sulfate, calcium carbonate, talc, clay, zinc white and the like in combination.

The steel plate reinforcing sheet according to the present invention has the following advantages as compared with a pressure-type temporary fixing reinforcing sheet that requires a conventional release paper.
That is, since it is not necessary to stick release paper, manufacturing cost can be reduced. In the pasting work on the automobile steel plate, the work is greatly reduced compared to the work of pasting the release paper after the worker peels off the release paper.
Conventional release paper has become waste, but since no waste is generated, it can contribute to the reduction of environmental burden.
In addition, when an operator has mistakenly pasted the reinforcing sheet, the re-sticking operation may be extremely difficult or a new reinforcing sheet may need to be pasted. In the case of a sheet, reattaching is extremely easy.
Furthermore, automation such as carrying a reinforcing sheet using an electromagnet, and sticking the reinforcing sheet to a steel sheet by switching off the electromagnet at a specified location is easily possible.
Since the performance as a steel plate reinforcing material is equal to or higher than that of conventional products, it can be used without any problem.
