〔産業上の利用分野〕
この発明は、タンク内壁面のライニング方法に係わり、
更に詳しくは二輪車や四輪車等に使用される鋼製の素材

ンク内壁面のライニング方法に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for lining the inner wall surface of a tank.
More specifically, the inner wall of vehicle fuel tanks, which are made of steel materials used in motorcycles and four-wheeled vehicles, is lined with a resin-based lining material to a specified thickness to prevent cracks from occurring during a collision or collision. The present invention relates to a method of lining the inner wall surface of a tank to effectively prevent fuel from leaking.
従来、二輪車や四輪車等の燃料タンクは、殆どが鋼製の
素材により成形されている。Conventionally, most fuel tanks for motorcycles, four-wheeled vehicles, etc. are made of steel.
また、航空機用のブラダ−型燃料タンクは、ゴム状弾性
体などより成形されている。Furthermore, bladder-type fuel tanks for aircraft are made of rubber-like elastic material or the like.
然しなから、前者の二輪車や四輪車等の燃料タンクの場
合には、素材が鋼製であるため、公知のプレス成型法に
より比較的簡単に成型でき、また低コストにて成型する
ことが出来る反面、内壁面が錆易く、しかも衝突時には
クランク等が入り易いために、衝突時等には燃料洩れに
よる火災が発生し易いと言う問題があった。However, in the case of the former fuel tanks for motorcycles and four-wheeled vehicles, the material is steel, so it can be relatively easily molded using a known press molding method, and can be molded at low cost. However, since the inner wall surface is easily rusted and the crank etc. are easily inserted in the event of a collision, there is a problem that a fire is likely to occur due to fuel leakage in the event of a collision.
また、後者の航空機用のブラダ−型燃料タンクの場合に
は、耐油性、耐水性に優れ、また柔軟性に富んでいるた
め、衝撃が加わっても簡単にクランク等が発生しないと
言う利点はあるが、成型時には一つずつの成形型が必要
であり、極めて高価となる問題があった。In addition, in the case of the latter, bladder-type fuel tanks for aircraft, they have excellent oil and water resistance, and are highly flexible, so they have the advantage of not easily cranking when subjected to impact. However, there was a problem in that each mold was required for molding, making it extremely expensive.
この発明は、かかる従来の課題に着目して案出されたも
ので、衝撃時にクランク等が発生しても燃料洩れ等がな
く、しかも錆の発生も防止でき、更に軽量で安価に製造
出来るタンク内壁面のライニング方法を提供することを
目的とするものである。This invention was devised by focusing on such conventional problems, and is a tank that does not leak fuel even if a crank or the like occurs during an impact, prevents rust, and is lightweight and inexpensive to manufacture. It is an object of the present invention to provide a method for lining an inner wall surface.
この発明は上記目的を達成するため、中空状に形成した
タンク本体の給排口から、一定量の耐水性を有し、かつ

や錆の発生を有効に防止出来、また安価に製造出来るよ
うにしたことを要旨とするものである。In order to achieve the above object, this invention injects a certain amount of lining material such as a thermoplastic resin that is water resistant and flexible when hardened, through the supply and discharge ports of a tank body formed in a hollow shape. By coating the lining material uniformly on the inner wall of the tank body and curing it to line the inner wall of the tank without rotating the tank body, fuel leakage and rust can be effectively prevented, and it is also inexpensive. The gist of this is that it can be manufactured in a number of ways.

で錆の発生もなく、更に安価に製造出来るものである。The present invention is configured as described above, and when a crack or the like occurs due to impact on the tank body, the flexible lining material such as rubber or resin that is lined on the inner wall surface of the tank body is Since there is no cranking, fuel leakage can be effectively prevented, and since the inner wall surface of the tank body is coated with a lining material, rust does not occur, and the tank can be manufactured at a lower cost.
以下、添付図面に基づき、この発明の詳細な説明する。 Hereinafter, the present invention will be described in detail based on the accompanying drawings.

一なコーテイング膜を形成する。The method for molding the tank body 1 described above is as follows:
is formed into a hollow shape by rotational molding using a steel material, and a predetermined amount of the above-mentioned lining material 2 is injected from the fuel injection port 3 of the tank body 1, and then the lining material 2 is injected 3 times per minute to
Rotate 20 times at a predetermined rotational speed to form a 1.5 mm to 2. A uniform coating film with Otxm flexibility is formed.
以上のように構成することにより、タンク本体ｌの内壁

、燃料洩れ等も発生しない。With the above configuration, the inner wall surface of the tank body l does not come into direct contact with fuel, etc., and therefore rust etc. do not occur.
Furthermore, even if a crack occurs in the tank body 1 due to the collision, no crack occurs in the internal lining material 2, so no fuel leakage occurs.

ある。This invention involves injecting a certain amount of a lining material such as a thermoplastic resin that is water resistant and flexible when hardened through the supply port of the tank body formed into a hollow shape as described above.
By applying the lining material uniformly to the inner wall of the tank body and curing it to line the inner wall of the tank without rotating the tank body, fuel leakage will not occur even if the tank body is cranked during an impact. It also has the effect of being lightweight and inexpensive to manufacture.
