Abstract
The utility model relates to a flame retardant, high-intensity and heat preserving type polyurea outerwear. The polyurea outerwear is characterized by comprising a polyurethane foaming layer (2), a first polyurea layer (3), a steel wire net (4), and a second polyurea layer (5) which are arranged on the outer surface of a tank body or a pipeline base material from inside to outside in sequence. The polyurea outerwear is prepared by the method comprising the following steps: (1) coating PU (Poly Urethane); (2) coating the first polyurea layer; (3) laying the steel wire net; (4) coating the second polyurea layer. The flame retardant, high-intensity and heat preserving type polyurea outerwear is fast to be constructed, high in intensity, and outstanding in flame retardant performance.
Description
Technical field
The utility model relates to a kind of flame-retardant high-strength insulation polyureas coat, is mainly used in the tank bodies of liquid gas carrier such as natural fuels or the insulation of pipeline.
Background technology
In natural gas carrier vessel, the tank that stores therein liquid methane is by different materials and can guarantee that the barrier layere of leak tightness forms.For storage and the transport of the liquid methane-163 DEG C of temperature, excellent insulation is indispensable.
In natural gas carrier vessel of new generation, be integrated into sealing in carrier (especially ship) structure and the tank of insulation and comprise two continuous leak tightness barrier layeres, the first barrier layere contacting with the product holding in tank and another are arranged on so-called the second barrier layere between the first barrier layere and carrier structure, and these two leak tightness barrier layeres and two adiabatic barrier layeres are alternately.
The second barrier layere is used for holding any seepage that may occur through the fluid cargo of this first barrier layere temporarily.
Therefore, under average (in seawater side or in the erosion of blue gas side), close barrier should guarantee to the leak tightness of blue gas reach at least ten five days (for connecting accumulator plant maximum duration) and therefore resistance to prolongation with seawater or with the contacting of blue gas (163 DEG C).
In order to reach the performance by international blue gas laws and regulations requirement, this double barrier or film are at present by current the first barrier layere (LNG contact with blue gas) of being made up of corrosion-resistant steel or INVAR (new SC1 concept) with by INVAR (NO96 technique) or what is called " sealing " the second barrier layere formation that TRIPLEX (for SC1 and MARK III technique) makes more widely now.Lasting at this barrier layere of normal work period the temperature of-100 to-120 DEG C.
But only double-deck tank body is also nowhere near, also need to be incubated processing outward at tank body, be usually said coat at the insulation construction of tank body outer cladding.
The coat of existing tank body or pipeline is prepared first spraying polyurethane (PU) foaming layer, then spray polyurea layer outside polyurethane foaming layer, then cut and be coated on outside polyurea layer with tin-plate.The defect of the method is:
One, the construction period long, hull enters dock while repairing, owing to cutting coated tin-plate construction slowly, can extend the length of the halt at dock, costs dearly.
Two, surface strength is low, impacts can produce pit with hammer on coat surface, and tank body is above deck exposed, once marine, emergency situations occurs, and anti-strike capability is poor, can have larger potential safety hazard.
Three, poor fire, in hull work progress, welding slag, molten iron that electric welding generates splash down on it, can cause fire.
summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of construct fast, intensity is high, the flame-retardant high-strength of good flame resistance insulation polyureas coat.
The purpose of this utility model is achieved in that a kind of flame-retardant high-strength insulation polyureas coat, it comprises polyurethane foaming layer, the first polyurea layer, wire net and the second polyurea layer, and described polyurethane foaming layer, the first polyurea layer, wire net and the second polyurea layer are set in turn in the outside face of tank body or pipeline base material from the inside to the outside.
Described wire net entirely coated or part is coated on outside the first polyurea layer.If hull interior conduit, wire net is only at the top that is laid on pipeline; If tank body, wire net needs complete coated.
In order to reach further heat insulation, antiseptic effect, be also coated with polyurethane white paint outward in the second polyurea layer.
The material selection corrosion-resistant steel of described wire net, aperture is 1-3mm.
Described polyurethane foaming layer is multiple-structure.
In one deck foam in multilayer polyurethane foaming layer, lay glass web.
Compared with prior art, the beneficial effects of the utility model are:
One, laying wire net is efficient and convenient, and short construction period has shortened hull and repaired the time, reduces service expenditure.
Two, intensity is high, and the setting of process wire net and two-layer polyurea layer has increased outer field intensity greatly, firmly impacts also can not produce any pit, distortion, high safety with hammer on coat surface.
Three, good flame resistance, in hull work progress, welding slag, molten iron that electric welding generates splash down on it, and wire net can produce and stop it, eliminates disaster hidden-trouble.
Brief description of the drawings
Fig. 1 is the section structure schematic diagram of the utility model flame-retardant high-strength insulation polyureas coat.
Wherein:
Base material 1, polyurethane foaming layer 2, the first polyurea layer 3, wire net 4, the second polyurea layer 5.
Detailed description of the invention
Embodiment 1:
Referring to Fig. 1, a kind of flame-retardant high-strength insulation polyureas coat that the utility model relates to, it is the surface coating polyurethane foaming layer 2 at tank body or pipeline base material, in outer coating the first polyurea layer 3 of polyurethane foaming layer 2, apply the second polyurea layer 5 outward at outer wire net 4, the wire net of arranging of the first polyurea layer 3.
If hull interior conduit, wire net is only at the top that is laid on pipeline; If tank body, wire net needs complete coated.
The material selection corrosion-resistant steel of described wire net 4, aperture is 1-3mm.
Embodiment 2:
In order to reach further heat insulation, antiseptic effect, outside the second polyurea layer 5 of embodiment 1, be also coated with polyurethane white paint.
