New to regenerate, to avoid existing metal tank poor corrosion resistance, service life is short, and to surrounding soil, there are the risks of secondary pollution.
Double-layer composite material oil storage tank it is possible to prevente effectively from problem above appearance.But oil storage tank prepared by existing composite material, leads
Poor electrical performance, modulus are relatively low.It can be with the higher twin-wall oil tank of anlistatig mechanical property it is therefore desirable to design research and development one kind.
Currently, gas station's oil storage tank, the most commonly used is SF double walled tanks, internal layer uses cylinder of steel, outer layer compound using staple fiber
Material is molded, and perforation gap is formed between ectonexine, to monitor inside and outside wall leakage scenarios in real time.Due to staple fiber composite wood
Expect that intensity is relatively low, bearing capacity is weaker；In addition, perforation gap is smaller, blind area is easily formed, can not ensure that the comprehensive security of monitoring can
It leans on.
It is 201210035844.0 separately to have China Patent No., discloses a kind of glass fiber stereoscopic reinforced double-layer oil tank,
The oil tank includes steel tank and fiberglass tank body, the steel tank and fiberglass tank body successively from internal layer to outer layer
Between for glass fibre solid enhance hollow layer, the glass fibre solid enhancing hollow layer include be wrapped on steel tank
Glass fibre solid enhancing cloth and resin spray glass fibre solid enhancing cloth on after expansion curing formed hollow layer.This
Leakage of the glass fiber stereoscopic reinforced double-layer oil tank of invention equipped with unique leak detection system energy identification of hydrocarbon or underground water, is changed
Can namely hunt leak out steel tank or fiberglass tank body leakage.Ensure that user stops using and repaiies in time at the first time
It is multiple, fundamentally prevent the extraneous possibility of inflammable and explosive or noxious material outflow, timely eliminates underground water and soil
Security risk.
Above-mentioned patent two-compartment oil tank is using steel tank and fiberglass tank body, the anlistatig mechanical property of steel
Difference, tank body poor corrosion resistance, service life are short.
Invention content
In order to overcome the double walled tank of the above-mentioned prior art antistatic and poor mechanical property, tank body poor corrosion resistance uses the longevity
Short defect is ordered, that the present invention provides a kind of mechanical properties is more excellent, antistatic property is good, the burn into of resistance to oil product continuously penetrates through
The steel of non-blind area-composite material twin-wall oil tank.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of steel-composite material double-walled oil tank, including steel inner tank body and outer tank body, it is characterised in that：The inner tank body
Inner wall be equipped with the anlistatig erosion resistant coating that resin matrix impregnation of carbon fibers is formed, the outer wall of inner tank body is equipped with epoxy resin antirust
Layer is equipped with three dimension stereo fabric and infiltrates the hollow structure layer being compounded to form with resin base between outer tank body and antirust coat.
The outer tank body is that resin matrix is combined with glass fiber material.
The double-walled oil tank is equipped with lysimetric test pipe and operation well manhole.
A kind of preparation method of steel-composite material double-walled oil tank, includes the following steps：
(1) carbon fiber that resin matrix impregnates is pasted onto on the inner wall of steel inner tank body and forms anlistatig erosion resistant coating；
(2) modified epoxy resin is sprayed on the outer wall of steel inner tank body and forms antirust coat；
(3) porous three-dimensional stereo fabric is compounded to form with resin matrix using contact method on the surface of antirust coat hollow
Layer structure sheaf, hollow layer structure sheaf inside form communicating structure；
(4) outer tank body is formed using resin matrix and glass fiber material composite winding on the surface of hollow structure layer.
Contact method in step (3) is that resin matrix is immersed on porous three-dimensional stereo fabric, then by porous three-dimensional
Stereo fabric is bonded in the surface of antirust coat.
Modified epoxy resin is to add anlistatig graphite powder, epoxy resin and stone in the epoxy in (2)
The ratio of ink powder is 1:0.2-0.3.
The present invention has the following advantages：
1, the inner surface of the steel inner tank body of twin-wall oil tank of the present invention coat one layer can be with the chemical mediator of resistance to oil product pair
The corrosion of box hat, and the erosion resistant coating that can prevent the coating of static charge accumulation from being formed to extending the service life of equipment, and can promote
Electrostatic scatters, prevents from causing security risk because of the accumulation of electrostatic；Its outer surface sprays one layer of epoxy-modified rust-proof coating
The antirust coat that surrounding medium corrodes its box hat is solved, while the antirust coat can improve the binding force with intermediate structure layer, improved
The overall mechanical properties of tank body.
2, porous three dimension stereo fabric and resin material are combined by intermediate structure layer of the invention using contact method.
Feature one is that porous three-dimensional stereo fabric forms the hollow structure layer of continuous perforation non-blind area, makes to exist in leakage medium
Line monitors.The hollow structure layer and outer casing shell steel construction that feature two, porous three dimension stereo fabric are formed form an entirety,
Improve the intensity of equipment.
3, the outer tank body of twin-wall oil tank of the present invention winds composite molding using glass fibre and resin-based materials.One,
Fiberglass oil tank shell solves the galvanic corrosion problems in soil environment.Secondly, winding shaping process, improve product
Production efficiency reduces production cost.Thirdly, product quality advantageously ensured that using computer numerical control winding process technology.
