Embodiment 1
[0027] A method for preparing an on-line monitoring composite material double-walled oil storage tank. The double-walled oil storage tank consists of an anti-corrosion layer 1, an inner tank structure layer 2, an intermediate structure layer 3 and an outer tank structure layer 4 from the inside to the outside. An online monitoring well 5 is arranged on the double-walled oil storage tank, and a monitoring and alarm system 6 monitors whether the double-walled oil storage tank leaks oil. The anticorrosion layer 1 is made of antistatic carbon fiber.
[0028] The preparation method of the composite double-walled oil storage tank monitored on-line comprises the following steps:
[0029] (1) Preparation of anti-corrosion layer: the resin matrix is impregnated with carbon fiber composite material, and wound on the surface of the mold to form an anti-corrosion layer;
[0030] (2) Preparation of the inner tank structure layer: winding the resin matrix and the glass fiber composite ma...

The invention discloses a preparing method for a composite material double-wall oil storage tank monitored online. The preparing method comprises the following steps that firstly, a carbon fiber composite material is immersed in a resin base body, and an antiseptic layer is formed on the surface of a die in a winding manner; secondly, the resin base body and a glass fiber composite material are wound to form an inner tank body structural layer; thirdly, a middle structural layer is formed on the surface of the inner tank body structural layer through a resin base and glass fiber three-dimensional fabric wetting contact method; fourthly, the resin base body and the glass fiber composite material are wound to form an outer tank body structural layer on the surface of the middle structural layer; and fifthly, an online monitoring well led to the middle structural layer is arranged on a tank body, and the middle structural layer is fully filled with a NaCl electric conduction mixed salt solution with the concentration being 25%-30%. The structure compressive property is improved. The through middle layer is fully filled with the mixed salt solution, the online monitoring facility is arranged on the top of the oil tank, and real-time online monitoring is conducted on safe running of the oil storage tank.
Description
technical field [0001] The invention belongs to the technical field of composite material oil storage tanks, and in particular relates to a preparation method of an on-line monitoring composite material double-wall oil storage tank. Background technique [0002] With the gradual strengthening of environmental protection awareness and the gradual improvement of relevant laws and regulations, the underground oil storage tanks used in gas stations are being replaced to avoid the risk of secondary pollution of the surrounding soil due to poor corrosion resistance and short service life of existing metal storage tanks. The double-layer composite oil storage tank can effectively avoid the above problems. However, the existing oil storage tanks made of composite materials have poor electrical conductivity and low modulus. Therefore, it is necessary to design and develop a double-wall oil storage tank with higher mechanical properties that can resist static electricity. [0003] C...
