Background technique
Ice bag is widely used in fields such as fruit freshness preserving, icing beverage refrigeration, medical domain refrigeration, food refrigerating and fresh-keeping, seafood meat preservation, carrier refrigerations, the cold-storage heat-preserving effect of ice bag determines primarily of its liner material, but the thermal insulating material that existing ice bag liner material is made primarily of individual layer aluminium foil, there is the defects such as cool-storage time is short, thermal insulation is poor, soundness is poor in this material, and does not generally have block-water effect.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provides a kind of heat-insulating composite material, can solve the defect that existing ice bag inner bag thermal insulating material exists.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of heat-insulating composite material, comprise: waterproof PVC film layer, nonwoven layer, expanded polyethylene foam layer, aluminium foil layer, described waterproof PVC film layer hot pressing is on the upper surface of nonwoven layer and link into an integrated entity with described nonwoven layer, the lower surface of described nonwoven layer adheres the upper surface at described expanded polyethylene foam layer by adhesive, described aluminium foil layer hot pressing is on the lower surface of described expanded polyethylene foam layer, the cavity of cellular structure is provided with in described expanded polyethylene foam layer, refrigeration agent is filled with in the cavity of described cellular structure.
In a preferred embodiment of the present invention, the thickness of described waterproof PVC film layer is 0.1-0.5 μm.
In a preferred embodiment of the present invention, the thickness of described expanded polyethylene foam layer is 3-8mm.
In a preferred embodiment of the present invention, the thickness of described aluminium foil layer is 2-4 μm.
The invention has the beneficial effects as follows: the present invention is by waterproof PVC film layer, nonwoven layer, expanded polyethylene foam layer and aluminium foil layer MULTILAYER COMPOSITE, there is good fastness, good heat-insulation effect, and in expanded polyethylene foam layer, be provided with the cavity of cellular structure, this cryogen is filled with in it at cavity, this material is made to have good cold-storage effect, in addition outerly adopt the waterproof PVC film layer with good block-water performance, water vapor permeable to be avoided in ice bag to outside bag.To pass through inside C, nonwoven layer, expanded polyethylene foam layer.
