完成するに至つた。 Conventionally, the three-layered hot water storage tank used as a hot water storage tank has an inner liquid layer made of unsaturated polyester and glass fiber, and due to its hot water resistance, corrosion resistance, and durability, the usable temperature is 80°C or lower. It was hot. When the temperature exceeds that temperature, the inner layer in contact with the liquid has been made of enameled steel plate or stainless steel plate, but these have the drawbacks of corrosion due to defects such as pinholes after many years of use, and are expensive. There is nothing that can be done. In order to solve these problems, the inventors of the present invention have conducted various studies and found that a polypropylene sheet is impregnated with a stretchable reinforcing fiber fabric, and at least a portion of the reinforcing fiber fabric is applied onto the unimpregnated surface of the polypropylene sheet. ,
By laminating and curing reinforced plastics made of thermosetting resin and reinforcing fibers (hereinafter simply referred to as reinforced plastics), the polypropylene layer and reinforced plastic layer are made extremely strong using the reinforcing fiber fabric as an intermediary. The inventors discovered that it is extremely effective to obtain a mechanically bonded composite material and use the polypropylene surface of the composite material as the liquid contact surface for the liquid layer on the inner surface of a hot water storage tank, leading to the completion of the present invention.

層として特に好適である。 Since the reinforced fiber fabric impregnated with the polypropylene sheet of the present invention has elasticity, it can be easily drawn into any shape by bending or vacuum forming, and can be formed into a relatively arbitrary shape. Because of the integration, the drawn polypropylene sheet does not deform after forming, and polypropylene has very good hot water resistance, making it particularly suitable as a liquid layer on the inner surface of a hot water storage tank.

維が挙げられる。 The hot water storage tank of the present invention is composed of three layers: an inner liquid layer 1, an intermediate heat insulating layer 2, and an outer skin layer 3.The inner surface polypropylene sheet layer 1a provides hot water resistance, and the plastic layer 1b enhances strength and rigidity. The hot water storage tank is formed by sharing the roles of an intermediate heat insulating layer 2 for heat retention, and an outer skin layer 3 for appearance and weather resistance. Second
1a in the figure is a polypropylene sheet layer impregnated with a reinforcing fiber fabric 4 having elasticity. The sheet itself preferably has a thickness of 0.5 to 3.0 mm, and may contain various commonly used additives and fillers. Examples of methods for impregnating a polypropylene sheet with a stretchable reinforcing fiber fabric include a continuous press-fitting method using heated rolls, a hot press-fitting method using a heated hydraulic press, and the like. The heating temperature in this case is preferably 140 to 155°C, which is 5 to 20°C lower than the melting point of polypropylene (MCI method). This polypropylene sheet has excellent hot water resistance but low strength and rigidity, so it is lined with a reinforced plastic layer using impregnated reinforced fiber fabric as a mediator.
The lack of strength and rigidity is compensated for. That is, a polypropylene sheet is impregnated with a stretchable reinforcing fiber fabric, leaving at least a portion of the fabric, and a reinforced plastic is laminated on the unimpregnated side of the fabric and cured. The stripped fabric is impregnated into the reinforcing plastic layer to form an extremely strong and integrated internal liquid layer. The reinforcing fiber fabric used here includes reinforcing fibers such as glass fiber, carbon fiber, vinylon fiber, Tetron fiber, polypropylene fiber, and Kevlar fiber, among which glass fiber is most suitable. These reinforcing fibers are woven into a harp-like tricot knitting or stockinette knitting to create a stretchable fabric. Examples of the thermosetting resin forming the reinforced plastic layer include unsaturated polyester resin, epoxy resin, and phenol resin, and examples of the reinforcing fiber include glass fiber.

れる。 Conventionally, there are sheets made by extruding a mixture of resin and glass chips on the market, but when bending or drawing by vacuum forming is performed, the glass fibers in the resin separate at the interface with the resin. This resulted in a decrease in strength and hot water resistance, and had the disadvantage that the internal solution seeped out during long-term use. On the other hand, since the polypropylene of the present invention is impregnated with a stretchable reinforcing fiber fabric, it easily follows deformation during bending and vacuum forming, and prevents interfacial peeling between the polypropylene sheet and the fabric. Does not occur. Furthermore, since the reinforced plastic is layered on the surface of the unimpregnated fabric and cured, the polypropylene and reinforced plastic are strongly integrated using the fabric as an intermediary, creating an inner surface liquid layer that has both hot water resistance, strength, and rigidity. It will be done.

First, 2000 g of a 1.5 mm thick polypropylene sheet and glass yarn were placed on a flat mold in a heated hydraulic press.
M
Approximately half of the fabric was pressed into the polypropylene sheet under hot press-fitting conditions of ~150°C, pressure of 20 Kg/cm 2 , and pressurization time of 60 seconds to obtain a polypropylene sheet impregnated with a stretchable reinforcing fiber fabric. Next, this polypropylene sheet is bent into a cylindrical shape with the woven side facing outward, the ends of the sheet are wrapped, and the outside and inside ends are welded using a polypropylene welding rod made of the same material as the sheet to form side walls. A bottom plate and an upper mirror plate were respectively created by shaping using vacuum forming. Next, by welding and joining these as shown in 5, 6, and 7 using a polypropylene welding rod, a storage tank made of the polypropylene layer of the inner surface liquid layer 1 was manufactured. And Polylite FG-283
(Unsaturated polyester resin manufactured by Dainippon Ink & Chemicals Co., Ltd.) A mixed resin containing 1.0 parts of methyl ethyl ketone peroxide as a catalyst and 1.5 parts of 0.6% cobalt naphthenate as an accelerator is applied to unimpregnated fabrics. After applying it to a certain surface and thoroughly impregnating it, 450 g/m 2 of chopped strand pine is laminated using a mixed resin of the same composition and cured to form a reinforced plastic layer that is strongly integrated with the polypropylene layer. A storage tank with an inner liquid layer 1 was obtained. Next, the side wall, bottom plate, and upper mirror plate of the outer skin layer 3, which had been previously formed by press molding using SMC molding material DICMAT-2454 (manufactured by Dainippon Ink and Chemicals Co., Ltd.), were incorporated. In this case, in order to maintain a uniform thickness of the intermediate heat insulating layer, a 70 mm thick spacer block 8 made of urethane block was incorporated. Next, two holes with a diameter of 12 mm were made in a part of the upper end plate, and urethane resin was injected into one of the holes to form the intermediate heat insulating layer 2. Finally, a manhole 9, which was separately formed in the same manner, was set to complete the cylindrical hot water storage tank.

Glass yarn on 1.5mm polypropylene sheet
A polypropylene sheet in which the glass cloth was pressed was created by stacking knitted glass cloth at 250 g/m 2 and passing it through a hot pressure roll heated to approximately 150℃.Then, the sheet was cut into 1300 mm x 1300 mm and 1000 mm x It was vacuum formed into a box shape of 1000mm x 150mm. In this case, the surface into which the glass cloth is pushed is the inside of the box. Next, this was set in a mold, three sheets of glass fiber (450g/ m2 continuous filament mat) were charged, and the surface was covered with Polylite PS-261 (unsaturated polyester resin manufactured by Dainippon Ink and Chemicals Co., Ltd.). ) for 100 copies,
A resin compound containing 50 parts of calcium carbonate, 1.0 part of methyl ethyl ketone peroxide as a catalyst, and 0.1 part of 0.6% cobalt naphthenate as an accelerator was poured on top of the 992 mm x 992 mm x 70
2 mm urethane foam, then charge 2 sheets of glass fiber (450 g/m 2 continuous filament mat) on top, and pour the resin compound onto the surface of the foam at a mold temperature of 80°C and a molding pressure of 10°C.
By press forming under the conditions of Kg/cm 2 and pressurizing time of 10 minutes, a unit panel board for a rectangular tank having a three-layer structure shown in FIG. 2 was obtained. These panel plates were joined with bolts and nuts via packing to obtain a panel type square hot water storage tank.
