Abstract
The utility model relates to a polyurethane foaming vacuum heat preservation layer. Seal and wrap the polyurethane foaming heat preservation layer with film and make the film and the polyurethane foaming heat preservation layer become vacuum. The heat preservation layer isolate the part of heat conduction of air to greatly improve the heat preservation property.
Description
Technical field the utility model relates to a kind of polyurethane insulating foam layer, especially needs to adopt the various occasions of polyurethane foamed heat insulating to adopt this kind polyurethane insulating foam layer, can improve heat insulation effect, and saves the polyurethane thermal insulating material.
The known polyurethane foamed heat insulating of background technique normally directly forms thermal insulation layer with the polyurethane foaming in the interlayer of reserving, or makes various polyurethane insulation coating members with the polyurethane foaming in mould.At present thisly directly also exist defective with foam filled insulation of polyurethane or the method that is incubated with the polyurethane insulation coating member, owing to have the air clearance between polyurethane insulation coating and the thermal insulator, particularly the air clearance between the polyurethane expanded beads forms air heat conduction, influence heat preservation effect, generally adopted the way that adds thick insulation layer to remedy this defective at present.
Summary of the invention influences the problem of heat insulation effect in order to overcome air clearance between polyurethane insulation coating and expanded beads.The utility model provides a kind of polyurethane foaming vacuum heat-insulating layer, this kind polyurethane foaming vacuum heat-insulating layer is on former polyurethane insulating foam layer basis, in its peripheral film wrapped of using, the sealing of shape pouch, to vacuumize in the film bag again, make in the film bag and the formation of the gap between polyurethane expanded beads vacuum, the path of having blocked air heat conduction increases substantially its thermal insulation property.Can suitably reduce the thickness of polyurethane insulation coating with this kind polyurethane foaming vacuum heat-insulating layer, save the polyurethane thermal insulating material.
The technological scheme that its technical problem that solves the utility model adopts is: outside the polyurethane insulating foam layer, with the film wrapped sealing, vacuumize in the bag with polyurethane insulation coating behind the environmental sealing and film wrapped formation, form the polyurethane vacuum heat-insulating layer.
The beneficial effects of the utility model are, owing to do not have air heat conduction in the polyurethane foaming vacuum heat-insulating layer, and the polyurethane insulating foam layer that its heat insulation effect is excellent and common, and can suitably reduce the thickness of thermal insulation layer, save thermal insulating material, the reduction product cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional structural map of the present utility model.
1. feeding ports among the figure, 2. film, 3. polyurethane insulating foam layer, 4. polyurethane expanded beads, 5. gap between particle, 6. relief opening.
Embodiment
Among Fig. 1, polyurethane insulating foam layer (3) external sealed is wrapped in film (2).The polyurethane thermal insulating material is to be filled in film (2) by feeding port (1), makes gap (5) between the particle that is full of polyurethane expanded beads (4) in the film (2) and forms naturally, forms polyurethane insulating foam layer (3); Stuffing box packing mouth (1), with the air in the gap (5) in the film (2) and between the polyurethane particle by relief opening (6) pump drainage, make in the film (2) and the polyurethane particle between gap (5) be vacuum state, sealing relief opening (6) forms polyurethane foaming vacuum heat-insulating layer.
Claims (2)
1. a polyurethane foaming vacuum heat-insulating layer outside the polyurethane insulating foam layer, seals with film wrapped, and it is characterized in that: polyurethane insulating foam layer external sealed is wrapped in film.
2. polyurethane according to claim 1 foaming vacuum heat-insulating layer is characterized in that: the gap is a vacuum state in the film and between the polyurethane particle.
