Embodiment 1

[0040] Such as figure 1 As shown, a buried FRP double-wall oil storage tank adopting liquid medium monitoring, it includes: inner tank body (1), outer tank body (2) and hollow layer (3), described hollow layer (3 ) is formed by bonding the outer wall of the inner tank body (1) and the inner wall of the outer tank body (2) by a three-dimensional hollow fabric, and the outer wall of the outer tank body (2) is provided with a solid reinforcing rib (4), which is connected with the hollow layer (3 ) connected to the water storage tank (5), the manhole (6) and the lifting lug (7);

[0041] The inner tank body (1) is composed of an inner lining layer, an inner anti-seepage layer, a structural layer and an outer anti-seepage layer from the inside to the outside;

[0042] The outer tank body (2) is composed of an inner anti-seepage layer, a structural layer and an outer anti-seepage layer from the inside to the outside.

[0043]The above-mentioned buried FRP double-walled oil storage...

Embodiment 2

[0051] A method for preparing a glass fiber reinforced plastic double-wall oil storage tank monitored by a liquid medium, comprising the following steps:

[0052] a. Production of half-inner tank

[0053] First, lay polyester film on the half-inner tank winding mold with head, start the power device to make the winding mold rotate around the mandrel;

[0054] Then on the winding mold, the glass fiber surface mat is impregnated with thermosetting resin, and the inner liner is prepared by spraying or winding process; after the inner liner is cured, the surface of the inner liner is sprayed by spraying process, and the glass fiber jet yarn and thermosetting resin are sprayed at the same time , and then rolled to prepare the inner anti-seepage layer; after the inner anti-seepage layer is cured, the glass fiber reinforced yarn or fabric impregnated with thermosetting resin is laid on the surface of the inner anti-seepage layer by winding process to prepare the structural layer; the...

Abstract

The invention discloses a preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank monitored through a liquid medium. The glass fiber reinforced plastic double-wall oil storage tank comprises an inner tank body (1), an outer tank body (2) and a hollow layer (3). Three-dimensional hollow fabric is adhered to the outer wall of the inner tank body (1) and the inner wall of the outer tank body (2), so that the hollow layer (3) is formed. A solid reinforced rib (4), a water storage tank (5) communicated with the hollow layer (3), an inlet (6) and a lug (7) are arranged on the outer wall of the outer tank body (2). According to the buried glass fiber reinforced plastic double-wall oil storage tank, tensile modulus and mechanical strength are high, corrosion resistant performance and seepage resistant performance are good, petroleum products can be monitored online in real time, safety performance is high, weight is light and service life is long. The preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank is reasonable in technology design and strong in maneuverability. Compared with the prior art of a female die and injection forming technology, the preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank can greatly improve structure strength of a tank body, reduce device investment and raw material cost, save labor and improve production efficiency.

Description

technical field [0001] The invention relates to an oil storage tank, in particular to a buried FRP double-wall oil storage tank which is used in a gas station and is monitored by a liquid medium, and a preparation method thereof. Background technique [0002] With the rapid development of my country's automobile industry, the number of automobile gas stations is increasing day by day. In my country, oil storage tanks in gas stations generally adopt horizontal steel structures. Due to the influence of surrounding humid environment, stray current, oil erosion and other factors, the tank body is easily corroded. Corrosion not only greatly shortens the service life of the storage tank, but more seriously, it may cause the leakage of refined oil. Once refined oil leaks, it will not only cause serious pollution to the soil and groundwater resources that human beings depend on for survival, but also seriously threaten human health. [0003] The use of FRP double-wall oil storage ...
