Abstract
The utility model relates to a high strength insulation construction of low temperature jar body, its characterized in that: including first foam blanket (1), first foam blanket (1) is covered at jar body surface face, and the surface of this first foam blanket (1) is equipped with wire net (2), it has second foam blanket (3) to fill in the clearance of wire net (2) and first foam blanket (1) to second foam blanket (3) fill the mesh gap of wire net (2) full, and the surface of second foam blanket (3) is spouted and is had polyurea layer (4). This kind of high strength insulation construction of low temperature jar body is through laying the wire net on first foam blanket surface to use the slower PU liquid of foaming speed to fill down from the mesh of wire net in the clearance of wire net and first foam blanket, form the second foam blanket of surfacing, afterwards at its surface coating polyurea. The surfacing is smooth not to the utmost for the insulation construction who makes like this to need not to peg the wire net, insulation construction is airtight completely, has improved the heat preservation effect.
Description
Technical field
This utility model relates to the high-strength insulation structure of a kind of low temperature tank body, and the heat-insulation layer as low temperature tank bodies such as liquefied gas uses.
Background technology
In a new generation's natural gas carrier vessel, depositing the storage tank being incubated liquid, tank surface is coated with insulation construction and plays the effect that storage seals and is incubated, and is possible to prevent fluid seepage.
But when the liquefied gas heat insulation tank surface on ship was carried out heat-insulation layer making in the past, be by the scene at tank surface spray foam, re-lay steel wire, last spray polyurea completes to make.But internal PU foam-formed (needing polishing for reaching aesthetic froth bed) is depended in the outer surface molding of the insulation construction so made, and causes polyurea layer out-of-flatness, rough attractive in appearance；Simultaneously steel wire need nail on foam, complex process, and polyurea layer can not be filled up completely with in the gap of foam and steel wire, cause what polyurea layer can not spread to leave no gaps, there is the hidden danger entered in insulation construction of pouring water, have impact on heat insulation effect.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, it is provided that a kind of outer surface is mellow and full smooth, it is not necessary to peg steel wire, and the most airtight, it is ensured that the high-strength insulation structure of the low temperature tank body of heat insulation effect.
The purpose of this utility model is achieved in that
A kind of high-strength insulation structure of low temperature tank body, this insulation construction includes the first froth bed, first froth bed overlays on tank surface, the surface of this first froth bed is provided with steel wire, the gap of described steel wire and the first froth bed is filled with the second froth bed, and the second froth bed is full by the mesh gap filling of steel wire, and the surface of the second froth bed is sprayed with polyurea layer.
Described steel wire aperture is 1-3mm.
The material of described steel wire is rustless steel.
The thickness of described second froth bed is 0.1 ~ 10mm.
Polyurethane white paint it is also coated with outside described polyurea layer.
The material of described first froth bed uses the foam of fast foaming, and the material of the second froth bed uses the foam foamed at a slow speed.
Compared with prior art, the beneficial effects of the utility model are:
The high-strength insulation structure of this low temperature tank body is by laying steel wire on the first froth bed surface, and the PU liquid that use expansion rate is slower in the gap of steel wire and the first froth bed irrigates from the mesh of steel wire, the gap of steel wire and the first froth bed is filled up by PU liquid, and the mesh of steel wire is also filled up by PU liquid, PU liquid starts foaming, form the second froth bed, and gap is fully filled with, again the second froth bed surface is evened out beyond the part of steel wire, form the second froth bed of surfacing, subsequently at its surface spraying polyureas.The insulation construction so made surfacing not to the utmost is smooth, and without pegging steel wire, insulation construction is the most airtight, improves heat insulation effect.
Accompanying drawing explanation
Fig. 1 is the arrangement schematic diagram of the high-strength insulation body structure surface arc cystosepiment of this utility model low temperature tank body.
Fig. 2 is the top view of steel wire in Fig. 1.
Wherein: the first froth bed 1, steel wire the 2, second froth bed 3, polyurea layer 4.
Detailed description of the invention
See Fig. 1 and Fig. 2, this utility model relates to the high-strength insulation structure of a kind of low temperature tank body, this insulation construction includes the first froth bed 1, described first froth bed 1 uses the foam of fast foaming, first froth bed 1 overlays on tank surface, the surface of this first froth bed 1 is provided with steel wire 2, described steel wire 2 aperture is 1-3mm, and the material of steel wire 2 is rustless steel, the gap of described steel wire 2 and the first froth bed 1 is filled with the second froth bed 3, the thickness of this second froth bed 3 is 0.1 ~ 10mm, and the second froth bed 3 is full by the mesh gap filling of steel wire 2, second froth bed 3 uses the foam foamed at a slow speed, the surface of the second froth bed 3 is sprayed with polyurea layer 4, in order to reach the most heat insulation, antiseptic effect, polyurethane white paint it is also coated with outside polyurea layer 4.
The preparation method of the high-strength insulation structure of a kind of low temperature tank body is:
(1), the first froth bed spraying
At the low temperature resistant priming paint that tank surface spray last layer is the thinnest, after surface spraying PU, PU foam, form the first froth bed by spray gun.
(2), steel wire is laid
The steel wire originally cut out in advance is laid on the first froth bed surface.
(3), the second froth bed spraying
The PU liquid using expansion rate slower irrigates from the mesh of steel wire, the gap of steel wire and the first froth bed is filled up by PU liquid, and the mesh of steel wire is also filled up by PU liquid, PU liquid starts foaming, form the second froth bed, and gap is fully filled with, then the second froth bed surface is evened out beyond the part of steel wire, form the second froth bed of surfacing.
(4), polyureas spraying
At the surface spraying polyureas of the second froth bed, form polyurea layer.
