Abstract
The utility model discloses a kind of thermal insulation box body, it is integrally formed by rotational molding technique, it includes double Shell, the insulating between double Shell and the adhesion promoting layer for bonding double Shell and insulating, the insulating includes foamed polyurethane layer and the vacuum insulation panel being wrapped in foamed polyurethane layer, and the shore hardness and particle diameter of the material powder of the adhesion promoting layer are all higher than the shore hardness and particle diameter of the material powder of the double Shell.The utility model adds the roughness of PE surface of shell by the addition of adhesion promoter layer so that PE housings and polyurathamc with close adhesion, can improve the service life and heat-insulating property of thermal-insulating body；And vacuum insulation panel is implanted in casing, further improves the heat insulation effect of incubator.
Description
Technical field
It the utility model is related to a kind of thermal insulation box body.
Background technology
Rotational moulding incubator generally use polyethylene (PE) rotational molding technique is processed into double-decker, and heat-insulating heat-preserving material is most
Using hard polyurethane foam, its drawback essentially consists in：
1st, after due to polythene material rotation molding, surface is smooth so that is difficult between hard polyurethane foam and housing
Close adhesion, therefore when temperature changes larger, the air in polyurethane foam produces expanding with heat and contract with cold effect, will make froth bed and
Plastics wooden partition departs from, and so as to cause thermal insulation box body outer wall to deform, inner hollow, influences the outward appearance and heat-insulating property of product；
2nd, the heat insulation effect of rotational moulding incubator is further improved, it is generally real by increasing the thickness of heat-insulating heat-preserving material
It is existing, so that incubator is heavy.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of thermal insulation box body.
To achieve the above object, the utility model uses following technical scheme：
A kind of thermal insulation box body, is integrally formed by rotational molding technique, including double Shell, heat-insulated between double Shell
Heat-insulation layer and the adhesion promoting layer for bonding double Shell and insulating, the insulating include foamed polyurethane layer and
The vacuum insulation panel being wrapped in foamed polyurethane layer, the shore hardness and particle diameter of the material powder of the adhesion promoting layer are all higher than institute
State the shore hardness and particle diameter of the material powder of double Shell.
Further, the vacuum insulation panel includes hard forming glass fibers core layer and vacuum encapsulates core layer
Metal foil.
Further, the thickness of the insulating is 20-30mm, and the thickness of the vacuum insulation panel is 5-10mm.
Further, the material of the double Shell and adhesion promoting layer is polyethylene, polyethylene used by double Shell
Its shore hardness≤58HD of material, granularity are 40-60 mesh；Its shore hardness of polythene material is more than used by adhesion promoting layer
62HD, granularity are 20-30 mesh.
After adopting the above technical scheme, the utility model compared with background technology, has the following advantages that：
1st, the utility model adds the roughness of PE surface of shell by the addition of adhesion promoter layer so that PE housings and
Polyurathamc can substantially prolongs the service life of thermal-insulating body with close adhesion, while ensure that heat-insulating property, insulation effect
Fruit is good；
2nd, vacuum insulation panel is implanted in casing, in the case where thermal-insulating body thickness is certain, improves heat-insulating property.
Brief description of the drawings
Fig. 1 is the utility model box structure diagram.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Embodiment
As shown in figure 1, a kind of thermal insulation box body, is integrally formed by rotational molding technique, including double Shell 1, located at bilayer
The adhesion promoting layer 4 of insulating and bonding double Shell 1 and insulating between housing 1, the insulating include
Foamed polyurethane layer 2 and the vacuum insulation panel 3 being wrapped in foamed polyurethane layer.
Wherein, the shore hardness of the material powder of adhesion promoting layer 4 and particle diameter are all higher than the shore of the material powder of double Shell 1
Hardness and particle diameter, so as to which the inner surface in double Shell 1 after the completion of rotational moulding forms rough layer so that double Shell 1 and foaming
Polyurethane can be with close adhesion.In the present embodiment, double Shell 1 and adhesion promoting layer 4 are prepared using polyethylene powders, so that two
There is good adhesion strength between person.Wherein, its trade mark of polythene material powder that double Shell 1 uses for
LLDPE3204, its shore hardness≤58HD, granularity are 40-60 mesh；Its trade mark of polythene material powder is used by adhesion promoting layer
HD9000P, its shore hardness are more than 62HD, and granularity is 20-30 mesh.
Vacuum insulation panel 3 includes hard forming glass fibers plate and the metal foil of vacuum enveloping core layer, its thickness
For 5-10mm, the thickness of the insulating after preparation is 20-30mm.
Preparation flow：Vacuum insulation panel is positioned in a mold, by PE powder by the locating dowel prepared by PE materials
(LLDPE3204 and HD9000P) pours into rotational moulding in mould, heats up, and insulation, after double Shell is cooled and shaped, vacuum insulation panel is
It is embedded in double Shell 1, and gap is present between the inwall of double Shell 1, liquid polyurethane (PU) is injected into double Shell
1, by rotational moulding in double Shell 1 foaming, that is, form foamed polyurethane layer 2.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by scope of the claims.
