Abstract
The utility model relates to a ultralow temperature heat-preservation sandwich panel, belonging to the technical field of heat-preservation material manufacture, which is mainly composed of an outer steel plate (4) and an inner steel plate (1) arranged in parallel, a foam heat-preservation layer (2) arranged between the outer steel plate (4) and the inner steel plate (1), foam welding holes (3) distributed on the inner steel plate (1) alternately, and an anti-freezing paint layer (5). when manufactured, an appropriate foam spraying machine is used to spray polyurethane foam plastics at the space between the outer steel plate and the inner steel plate from the foam welding holes, after foaming, the foam welding holes are sealed by frozen welding wires, epoxy anti-freezing paint layer is spread on the surface of the inner steel plate. The utility model has reasonable design and can improve heat preservation effect, after actual inspection and application, the utility model is applied at below minus 55 DEG C to minus 63 DEG C, and in particular is applicable for instant freezing and storage of tunnies and similar rare fishes in deep sea.
Description
Technical field
The utility model relates to a kind of ultralow temperature insulation sandwich board, belongs to insulation material manufacturing technology field.
Background technology
Existing insulation sandwich board is mainly the version of filled polyurethane foamed plastic between two block plates, directly sprays foaming usually between two block plates, causes some position foamed plastic layer too closely knit, easily makes steel plate deformed; And some position influences heat insulation effect because of foaming the space that exists not in place, and this type of insulation sandwich board generally is applicable under 0～-18 ℃ of state and uses, is difficult to adapt to the instructions for use under the ultralow temperature state.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can adapt to the ultralow temperature insulation sandwich board of instructions for use under the ultralow temperature state.
The utility model is the ultralow temperature insulation sandwich board, comprises the outer steel plate and the interior steel plate that be arranged in parallel, places the insulating foam layer between outer steel plate and the interior steel plate, and steel plate is provided with foaming welding hole spaced apart in it is characterized in that.During manufacturing, respectively by spraying foamed plastic between foaming outside steel plate of welding hole and the interior steel plate, after foaming finishes, the foaming welding hole is sealed with freezing welding wire with spray bubble machine.
The cloth hole density of described foaming welding hole on interior steel plate can be 5～16 hole/rice
2The aperture of described foaming welding hole can be 20～50 millimeters.Described foaming welding hole can be even distribution setting on interior steel plate.
The thickness of described insulating foam layer can be 200～500 millimeters.The material of described insulating foam layer can be rigid foams such as polyurethane or epoxy resin.
The thickness of described outer steel plate can be 10～20 millimeters.The thickness of steel plate can be 8～16 millimeters in described.Surface of steel plate also can apply antifreeze enamelled coating in described.
The utility model is reasonable in design, foaming welding hole spaced apart is offered in employing on steel plate, during fabrication with the pressure-air of expanded materials such as polyurethane by dry oil free, spray between outer steel plate and the interior steel plate by the foaming welding hole with special use spray bubble machine, effectively guaranteed the evenly closely knit of insulating foam layer.Overcome the too closely knit shortcoming that easily makes steel plate deformed, has the standoff effects heat insulation effect of insulating foam layer in the prior art.The utility model can effectively improve heat insulation effect, through practice examining and application, is applicable under-55 ℃～-63 ℃ temperature and uses, and is specially adapted in the deep sea fishing the instant chilled storage to famous and precious fish such as tunas.

Fig. 2 is an A-A face structure cutaway view shown in Figure 1.
The specific embodiment
The utility model places the insulating foam layer 2 between outer steel plate 4 and the interior steel plate 1 mainly by outer steel plate 4 that be arranged in parallel and interior steel plate 1, foaming welding hole 3 spaced apart on the steel plate 1 in placing, antifreeze enamelled coating 5 formations such as grade on steel plate 1 surface in being coated on.During manufacturing, respectively by spraying polyurethane foam plastics between foaming welding hole 3 outside steel plates 4 and the interior steel plate 1, after foaming finishes, with freezing welding wire foaming welding hole 3 is sealed, at the antifreeze enamelled coating of interior steel plate 1 surface-coated epoxy resin with special-purpose spray bubble machine.
