Problems solved by technology

[0004] For FRP acid storage tanks, there are many defects in current FRP acid storage tanks.
Due to the large difference in expansion coefficient between FRP and steel, FRP is prone to thermal expansion, so after a period of use, the FRP will fall off from the metal due to the expansion of FRP, and even the FRP acid storage tank will burst and cannot continue to be used; in addition, The current FRP acid storage tank is difficult to completely drain the acid in it, which makes cleaning difficult

Embodiment 1

[0052] Such as Figure 1-7 As shown, a glass fiber reinforced plastic acid storage tank includes six side panels, and the six side panels include a first side panel 17, a second side panel 6 opposite to the first side panel, a front panel, a rear panel, a top panel 2 and a bottom panel 15. The six side panels form a hexahedron; each corner of the hexahedron is provided with an arc-shaped filling body 12, and the arc-shaped filling body is made of a paste-like flexible corrosion-resistant adhesive.

[0053] Each side plate includes a support frame 100; one side of the support frame is provided with an adhesive layer 400, a glass steel plate layer 500 and a glass fiber reinforced plastic cloth laminate 60 in sequence; the glass fiber reinforced plastic cloth laminate 60 includes several layers of glass fiber cloth layers 602 ; The adjacent glass fiber cloth layers 602 are bonded by the resin layer 601 .

[0054] Preferably, the support frame can be made of common metal material...

Embodiment 2

[0060] This embodiment is based on Example 1, in order to further enhance the direct adhesive force between the adhesive layer and the support frame, and prevent the support frame and the adhesive layer from being peeled off due to excessive thermal expansion and contraction stress. . In this embodiment, the adhesive layer is improved.

[0061] Such as Figure 8 As shown, the adhesive layer is a flexible and toughened layer, and the flexible and toughened layer is made of a paste-like flexible corrosion-resistant adhesive.

[0062] The paste-like flexible corrosion-resistant adhesive is made by the following preparation method, including steps:

[0063] A. After heating the epoxy resin, dilute it to a fluid state with an epoxy resin diluent to obtain a flowing epoxy resin;

[0064] B, after mixing flow epoxy resin and dibutyl phthalate, obtain flow dynamic toughening resin;

[0065] C. After mixing the fluid dynamic toughening resin with the coupling agent, the fluid dynam...

Embodiment 3

[0087] In order to further solve the technical problem of expansion and cracking of the FRP acid storage tank caused by expansion stress, this embodiment further optimizes the FRP acid storage tank on the basis of Embodiment 2 as follows.

[0088] Such as Figure 1-6 Shown, a kind of FRP acid storage tank, described FRP acid storage tank comprises six side plates, and described six side plates are all made of side plates; Described six side plates comprise first side plate 17, and The second side plate 6, the front plate, the rear plate, the top plate 2 and the bottom plate 15 opposite to the first side plate; the six side plates surround a hexahedron; each corner of the hexahedron is provided with an arc-shaped filling body 12, The curved filling body is made of paste-like flexible corrosion-resistant adhesive. The first side plate is connected with the second side plate through anti-expansion and contraction rods 8 . Such as figure 2Shown in the figure is the connecting ...

Abstract

The invention discloses a glass fiber reinforced plastic acid storage tank and a preparing method. The glass fiber reinforced plastic acid storage tank comprises six side plates including the first side plate, the second side plate opposite to the first side plate, the front plate, the rear plate, the top plate and the bottom plate. A hexahedron is defined by the six side plates. Each corner in the hexahedron is provided with an arc-shaped filler made of a pasty flexible anticorrosion adhesive. The preparing method includes the steps of preparing the six side plates according to specifications, attaching the six side plates into the hexahedron through adhesive layers, filling each corner in the hexahedron with the corresponding arc-shaped filler through the corresponding adhesive layer, and conducting curing to obtain the glass fiber reinforced plastic acid storage tank. The glass fiber reinforced plastic acid storage tank solves the problems of stripping and expansion cracking due toexpansion of an existing glass fiber reinforced plastic acid storage tank, and the service life of the glass fiber reinforced plastic acid storage tank is prolonged.

Description

technical field [0001] The invention belongs to the technical field of glass fiber reinforced plastic acid storage tanks, and in particular relates to a glass fiber reinforced plastic acid storage tank and a manufacturing method thereof. Background technique [0002] Storage tanks are used to store refined chemical substances such as acids and bases, alcohols, gases, and acids. Storage tanks are widely used in North China. According to different materials, there are generally: polyethylene storage tanks, polypropylene storage tanks, glass fiber reinforced plastic storage tanks, ceramic storage tanks, rubber storage tanks, stainless steel storage tanks, etc. [0003] The steel sealed container used to store acid or gas is the steel storage tank. The steel storage tank project is an indispensable and important foundation for industries such as petroleum, chemical industry, grain and oil, food, fire protection, transportation, metallurgy, and national defense. Facilities, larg...
