本発明は水タンク用パネルの製造法に関するも
のであり、操作が簡単であり、且つ強度の大きい
耐蝕性の良好な水タンク用パネルを得ることので
きる、工業的な製造法を提供することを目的とす
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing water tank panels, and is an industrial method that is easy to operate, and can produce water tank panels with high strength and good corrosion resistance. The purpose is to provide a manufacturing method.
水タンク、油タンク等のタンク用パネルは周縁
部に立上りフランジ部を有する箱型方形の形状を
有し、このフランジ部で該パネルを隣接のパネル
と結合することによつてタンクが組立てられる。 Panels for tanks such as water tanks and oil tanks have a box-like rectangular shape with a rising flange at the periphery, and the tank is assembled by joining the panel to an adjacent panel at the flange.
水タンクは0.7Kg／cm2程度乃至それ以上の水圧

の水タンク用パネルを製造法には次のような難点
があつた。 The water tank must withstand water pressure of approximately 0.7 kg/cm 2 or more. Water tanks can be constructed from various materials, but if corrosion resistance is required, it is preferable to use FRP. There is no known method for manufacturing panels for water tanks, and the conventional method for manufacturing panels for water tanks has the following drawbacks.
FRPは液状の熱硬化性樹脂を硝子繊維よりな

硬化FRPと云う）を硬化せしめることによつて
製造することができる。しかしながらその都度樹
脂を補強体に含浸させるのは操作及取扱いが面倒
であるだけでなく、未硬化FRP中の硝子繊維量
割合（GCと云う）にバラツキが生じたり、或は
使用中に樹脂粘度が変化したりし易く、均質な製
品の得難い難点がある。 FRP can be manufactured by impregnating a reinforcing body made of glass fiber with a liquid thermosetting resin and curing this resin-impregnated reinforcing body (referred to as uncured FRP). However, impregnating the reinforcing body with resin each time is not only cumbersome to operate and handle, but also causes variations in the proportion of glass fibers (GC) in uncured FRP, or the resin viscosity increases during use. It is difficult to obtain a homogeneous product because it is easy to change.
このため硝子繊維束に増粘剤を含む液状の熱硬

られる利点を有している反面次のような難点を有
する。 For this purpose, a sheet molding compound (hereinafter referred to as
SMC) is widely used for FRP molding, and although this method has the advantages of being easy to handle and operate and producing homogeneous products, it has the following disadvantages.
一般にFRPの強度は、他の条件が一定の場合、
使用する硝子繊維束の長さを大とする程大となる
傾向を有する。このため強度の大きいFRP、例

続した硝子繊維束よりなるマツト（コンテイニユ
アスストランドマツト、以下CSMと略称）を使
用することが必要とされて来た。しかしながら、
補強体としてCSMを使用したSMCは成型性が悪
く欠肉等が生じ易い。 Generally, the strength of FRP is, when other conditions are constant,
It tends to increase as the length of the glass fiber bundle used increases. For this reason, when manufacturing FRP with high strength, for example, panels for water tanks with a pressure resistance of 0.7 kg/cm 2 or more, it is necessary to use pine made of extremely long, preferably continuous glass fiber bundles (hereinafter referred to as continuous strand pine). It has become necessary to use CSM (abbreviated as CSM). however,
SMC using CSM as a reinforcing body has poor moldability and is prone to underfilling.
このため、強度の大きい水タンク用パネルを
SMCのみを用いて工業的に製造することができ
ず、従来水タンク用パネルをSMCを用いて製造
する場合CSMの薄層で型面を覆い、ついでこの
CSMに所定厚みの2.5cm程度の長さの硝子繊維束
切断物を補強体として用いたSMCを重ね、該型
と対をなす型で押圧し加熱する方法が採用されて
いた。 For this reason, strong water tank panels are required.
Conventionally, when water tank panels were manufactured using SMC, the mold surface was covered with a thin layer of CSM, and then this
The method employed was to stack an SMC made of cut glass fiber bundles with a predetermined thickness of about 2.5 cm in length as a reinforcing body on a CSM, and press and heat it with a mold paired with the mold.
この方法によるときは、SMC中の樹脂が型の
挟圧、加熱によつてCSMに向つて流動する。従

法によるときは強度の大きいFRPをうることが
できるがSMCのみを用いる方法に比し操作が煩
雑であるのみならず、表面層中の樹脂の分布が不
均一となつたり、樹脂とCSMの馴染みが不良と
なつたりすることもあり、又得られたパネルの強
度も必らずしも充分と云えない難点があつた。 When using this method, the resin in the SMC flows toward the CSM due to the compression and heating of the mold. Therefore, when using this method, liquid resin must be added in advance.
Even if it is not impregnated with CSM, the surface layer is CSM.
You can get reinforced panels with. When using this method, FRP with high strength can be obtained, but not only is the operation more complicated than the method using only SMC, but the distribution of the resin in the surface layer becomes uneven, and the relationship between the resin and CSM increases. There were also disadvantages in that the fit may be poor, and the strength of the resulting panels was not necessarily sufficient.

ある。 The inventor of the present invention solved these difficulties and conducted repeated research to find a method for industrially manufacturing a water tank panel that is easy to operate, homogeneous, and has great strength. % length 8
Glass fiber bundle of cm or more and 1-5 cm of 5-80wt%
A sheet molding compound using pine made of glass fiber bundles as a reinforcing body is made into a box-shaped rectangular female mold with a rising flange on the edge, and a rectangular mold with an area slightly smaller than the square at the bottom of the box shape. The inventors have discovered that very suitable results can be obtained by curing the resin by applying pressure and heating with a pair of molds consisting of a male mold and a male mold, and have proposed the present invention.
何故このような結果が得られるのか明らかでは
ないが、上述のSMC（以下SMCという）を構成

を用いて例えば水タンク用パネルを製造しても、
均質な、欠肉等のないパネルをうることができ、
又短かい硝子繊維束が混入されているに拘らず、
強度の充分大きいパネルの得られることが判明し
た。 It is not clear why such a result is obtained, but the reinforcing body that constitutes the SMC (hereinafter referred to as SMC) described above has extremely good fluidity despite the use of long glass fiber bundles. , even if a panel for a water tank, for example, is manufactured using only SMC,
It is possible to obtain homogeneous panels with no missing parts, etc.
Also, despite the inclusion of short glass fiber bundles,
It has been found that a panel with sufficiently high strength can be obtained.
次に本発明を更に具体的に説明する。 Next, the present invention will be explained in more detail.
本発明においては８cm以上の硝子繊維束、好ま

繊維束を用いることにより成型性、強度の特に優
れたSMCを得ることができる。 In the present invention, a glass fiber bundle having a length of 8 cm or more, preferably a glass fiber bundle cut into a length of 12 to 200 cm (hereinafter referred to as a long fiber bundle) is used. If the length of the glass fiber bundle is less than 8 cm, a panel with sufficient strength cannot be obtained. By using glass fiber bundles with a length of 12 to 200 cm, it is possible to obtain SMC with particularly excellent moldability and strength.
そして長尺繊維束95〜20wt％、５〜80wt％の、
長さ１〜５cmの硝子繊維束（以下短繊維束とい

い。又短繊維束の量が５％以下では充分な効果が
得られず、又その量が80％以上となると充分な強
度を有するパネルを得ることができない。 And long fiber bundles 95-20wt%, 5-80wt%,
Glass fiber bundles (hereinafter referred to as short fiber bundles) having a length of 1 to 5 cm are mixed as uniformly as possible to form a mat-like product (hereinafter referred to as the main mat-like product).
If the short fiber bundle length is less than 1 cm, the strength of the FRP product will decrease, and it will be difficult to manufacture SMC.
Above this, SMC with sufficient fluidity cannot be obtained. Further, if the amount of short fiber bundles is less than 5%, a sufficient effect cannot be obtained, and if the amount is more than 80%, a panel with sufficient strength cannot be obtained.
なお、硝子繊維束としては直径６〜15μの硝子

A predetermined amount is continuously applied onto a resin film, a long glass fiber bundle and a short glass fiber bundle are dropped onto the resin film so that they are mixed as uniformly as possible, and then covered with another synthetic resin film and rolled. The glass fiber bundle is impregnated with the resin composition by compressing the glass fiber bundle, and the bundle is rolled up into a cylindrical shape and cured to thicken the resin composition to form an SMC.

It is appropriate to set it at around Kg/cm 2 .

The size of the present SMC is sufficient to cover almost the top surface of the mold, and there is no need to bend the present SMC to cover the side surface of the male mold corresponding to the flange portion. When the SMC is heated while being pressed with a box-shaped female mold that is paired with the mold, it becomes a book.
