Description
【０００１】[0001]
この考案は自動車用板ばねを構成する板ばね部材の表面を被覆して錆を防止す る防錆塗装膜に関する。 The present invention relates to a rust preventive coating film that covers the surface of a leaf spring member that constitutes a leaf spring for an automobile to prevent rust.
【０００２】[0002]
従来、自動車のクッションとして用いる板ばねは、長さの異なる数枚の板ばね 部材を重ねで構成されるが、その板ばね部材の表面に防錆を目的として形成する 防錆塗装膜は、ジンクリッチ塗料を浸漬法により塗布することによって形成して いる。 Conventionally, leaf springs used as cushions for automobiles are constructed by stacking several leaf spring members with different lengths.The rust-preventive coating film formed on the surface of the leaf spring members for the purpose of rust prevention is zinc. It is formed by applying the rich paint by the dipping method.
【０００３】[0003]
しかしながら、上記したジンクリッチ塗装による防錆塗装膜にあっては、防錆 性が良好であるものの擦れ負荷に対する密着力に欠け、例えば板ばね部材が重な り合う部分では塗装が擦られて剥がれてしまうことがあり、従って板ばね部材同 士の合い面にて防錆塗装膜が剥離し、ここから錆が発生することが多かった。 また、どぶ漬けによるジンクリッチ塗装においては、亜鉛膜の厚みにばらつきが 生じ易く、これを均一に形成するためには難しい条件設定や、塗料に対して二度 漬け若しくは三度漬けする行程管理が必要となり、コスト高を招いていた。 However, the above-mentioned zinc-rich coating anti-corrosion coating film has good anti-corrosion properties, but lacks the adhesion force against rubbing load. Therefore, the anticorrosive coating film peeled off at the mating surfaces of the leaf spring members, and rust often occurred from there. Also, in zinc-rich painting by dobu-zuke, the thickness of the zinc film is likely to vary, and it is difficult to set uniform conditions and to control the process of dipping the paint twice or three times. It was necessary and costly.
【０００４】 本考案の課題は、ジンクリッチ塗装に代り、塗装層の均一化が容易で、且つ板 ばねに対する密着性が良く擦れ負荷に強い板ばねの防錆塗装膜を提供することに ある。An object of the present invention is to provide a rust-preventive coating film for a leaf spring, which is easy to make the coating layer uniform, has good adhesion to the leaf spring, and is resistant to rubbing load, instead of the zinc rich coating.
【０００５】[0005]
上記した課題を解決する為に本考案は、板ばね部材の表面に塗布するゴムプラ イマー層とこの上に重ねて塗布するゴム糊層とからなるものである。 In order to solve the above-mentioned problems, the present invention comprises a rubber primer layer applied on the surface of the leaf spring member and a rubber glue layer applied over the rubber primer layer.
【０００６】[0006]
以上の手段によれば、板ばね部材の表面に塗布されるゴムプライマー層は板ば ね部材に対して弾性的に密着して板ばねの全面を被覆し、錆の発生を防止する。 また、ゴムプライマーは、板ばね部材の表面に塗布された際にはその固形分が等 しく分散して均一なゴム膜を形成し、ゴム糊層に対しては接着強化材として作用 する。 According to the above means, the rubber primer layer applied to the surface of the leaf spring member elastically adheres to the leaf spring member to cover the entire surface of the leaf spring and prevent rusting. Further, when the rubber primer is applied to the surface of the leaf spring member, its solid content is evenly dispersed to form a uniform rubber film, and acts as an adhesion strengthening material for the rubber glue layer.
【０００７】 上記したゴムプライマー層の上に塗布されるゴム糊層は上記したゴムプライマ ーを介して板ばね材に対して強く接着し、ゴムプライマー層と共に擦れ負荷に追 従して弾性変形する緩衝層として働き、また、塗布の際には上記ゴムプライマー 同様に均等なゴム層を形成する性質を有する。The rubber glue layer applied on the above-mentioned rubber primer layer strongly adheres to the leaf spring material through the above-mentioned rubber primer, and it is elastically deformed by rubbing with the rubber primer layer and following the load. It functions as a layer and has the property of forming a uniform rubber layer upon application, like the rubber primer.
【０００８】[0008]
本考案は以上説明したように、板ばね材の表面にゴムプライマー層とゴム糊層 とからなる防錆塗装膜を形成するものであるから、従来のジンクリッチ塗装によ るものと比較すると、板ばね部材に対する密着性が良好であると共に、両ゴム層 が擦れ負荷に追従して弾性的に変形することにより擦れ負荷を効果的に緩衝して 剥がれを防止することができるので、擦れ負荷の生じる板ばね部材の重ね部分の 塗装膜が剥がれて同部分から錆が発生するようなこともない。 As described above, the present invention forms a rust-preventive coating film consisting of a rubber primer layer and a rubber glue layer on the surface of a leaf spring material. Adhesion to the leaf spring member is good, and both rubber layers elastically deform following the rubbing load to effectively cushion the rubbing load and prevent peeling. There is no possibility that the coating film on the overlapping portion of the leaf spring member will be peeled off and rust will be generated from that portion.
【０００９】 また、ゴムプライマーとゴム糊は固形分の溶解性に富み、これを塗布すること により均一な塗布膜ができる。よって塗装膜を均一に形成して良好な防錆性を維 持する為の行程管理を容易に行うことができ、コストの低減をも図ることができ る。Further, the rubber primer and the rubber paste have a high solid content solubility, and by applying them, a uniform coating film can be formed. Therefore, it is possible to easily control the process for uniformly forming the coating film and maintaining good antirust property, and it is possible to reduce the cost.
【００１０】[0010]
以下、本考案の一実施を図面に基づいて説明する。 図１にて示す板ばねは長さの異なる数枚の板ばね部材ａを重ね合わせことにより 構成してある。 An embodiment of the present invention will be described below with reference to the drawings. The leaf spring shown in FIG. 1 is constructed by stacking several leaf spring members a having different lengths.
【００１１】 板ばね部材ａは図２によって示すように、全面に防錆塗装を施してから板ばね として組み付けるものであり、その防錆塗装は図２における拡大図にて示すごと く、板ばね部材ａの表面に塗布するゴムプライマー層１と、その上に重ねて塗布 するゴム糊層２とから成っている。As shown in FIG. 2, the leaf spring member a is to be assembled as a leaf spring after applying rust prevention coating to the entire surface. The rust prevention coating is as shown in the enlarged view of FIG. It comprises a rubber primer layer 1 applied on the surface of the member a and a rubber glue layer 2 applied on top of it.
【００１２】 一層めのゴムプライマー層１は、ゴムプライマーの原液を溶剤にて薄めたもの をスプレー塗布する。そして板ばね部材ａの表面に塗布されたゴムプライマーは 、その後の溶剤の揮発に伴って乾燥し、その後、空気中の水分を吸収して自然硬 化する。For the first rubber primer layer 1, a stock solution of the rubber primer diluted with a solvent is spray-coated. The rubber primer applied to the surface of the leaf spring member a dries as the solvent volatilizes thereafter, and thereafter absorbs moisture in the air and naturally hardens.
【００１３】 上記したように板ばね部材ａに対してスプレー塗布されたゴムプライマーは、 その固形分が等しく分散する性質に富み、よって硬化後には均一なゴム膜が形成 される。また、上記ゴムプライマーは金属地に対する密着性が良好であると共に 、ゴム糊層２を板ばね部材ａに対して強固に接着させる接着強化材としての働き がある。As described above, the rubber primer spray-coated on the leaf spring member a is rich in the property that the solid content is evenly dispersed, so that a uniform rubber film is formed after curing. Further, the above-mentioned rubber primer has good adhesion to a metal material and also has a function as an adhesion reinforcing material for firmly adhering the rubber glue layer 2 to the leaf spring member a.
【００１４】 ゴム糊層２は、上記したゴムプライマー層１と同様に溶剤で薄めたものをスプ レー塗布するか若しくは刷毛塗りすることにより塗布する。塗布されたゴム糊は 自然加硫し、上記したゴムプライマー層２を介して板ばね部材ａに対し強固に接 着する。尚、上記の如く形成されたゴム糊層２はゴムプライマー層１よりも厚く 、良好な弾性を発揮する。The rubber glue layer 2 is applied by spray-coating or brush-coating with a solvent, as in the case of the rubber primer layer 1 described above. The applied rubber paste is naturally vulcanized and firmly adheres to the leaf spring member a via the rubber primer layer 2 described above. The rubber glue layer 2 formed as described above is thicker than the rubber primer layer 1 and exhibits good elasticity.
【００１５】 上記したように防錆塗装を施した板ばね部材ａは、前記したように長さの異な るもの同士を所定枚数重ね合わせて板ばねとして組み付けた後、該板ばねの表面 に化粧用の黒塗装をスプレー塗布して仕上げる。尚、この黒塗装は化粧用のもの であるために省略することもできる。As described above, the leaf spring member a coated with the rust preventive composition is assembled as a leaf spring by laminating a predetermined number of pieces having different lengths as described above, and then applying the makeup to the surface of the leaf spring. Finish by spraying a black paint for. Since this black coating is for makeup, it can be omitted.
【００１６】 以上の如く構成した板ばねは、防錆塗装膜をゴムプライマー層１とゴム糊層２ から構成したものであるから、板ばね部材ａに対する防錆塗装膜の密着性が非常 に高くなる上に、板ばね部材ａ同士の合い面において擦れ負荷が生じる状態にあ っても、両ゴム層１，２がその擦れ負荷に追従して弾性的に変形するので、擦れ 負荷を効果的に緩衝し、塗装膜の剥がれを防止することができる。したがって、 従来のもののように、擦れ負荷が頻繁に生じる板ばね部材の重ね部分の塗装膜が 剥がれて同部分から錆が発生するうような不具合もない。In the leaf spring constructed as described above, the rust preventive coating film is composed of the rubber primer layer 1 and the rubber glue layer 2, so that the adhesion of the rust preventive coating film to the leaf spring member a is very high. Moreover, even if a friction load is generated on the mating surfaces of the leaf spring members a, both rubber layers 1 and 2 are elastically deformed following the friction load, so that the friction load is effective. It is possible to prevent the peeling of the coating film by buffering. Therefore, unlike the conventional one, there is no problem that the coating film of the overlapping portion of the leaf spring member, which is frequently subjected to a rubbing load, is peeled off and rust is generated from the portion.
【００１７】 また、ゴムプライマー層１とゴム糊層２とは塗布する際に固形分が等しく分散 する性質に富むので、その塗装膜を均一に形成することが容易である。よって防 錆塗装膜を均一に維持する為の行程管理も容易になり、コストの低減を図ること ができる。Further, since the rubber primer layer 1 and the rubber glue layer 2 are rich in the property that the solid content is evenly dispersed when applied, it is easy to uniformly form the coating film. Therefore, the process for maintaining the rust preventive coating film evenly becomes easy, and the cost can be reduced.
