Abstract

A plastic refrigerator lining solves the problem of refrigerator electric leakage, achieves the effect of insulation better, and reduces cost for users.

Description

The refrigerator lining of plastics

Technical field

The utility model relates to a refrigerator, and wherein the plastic lining material is made.

Background technology

At the health liner of producing refrigerator, paper from plastic material production, by the high impact polystyrene material method that is squeezed, use these tables in the thermoforming process, the shape that it is final, liner between state artistic expression polyurethane injects and the exterior wall of health, due to the blowing agent that injects polyurethane cause chemical degradation process and use, the sheet resistance of plastic fuselage liner contact polyurethane material increases reinforcement material, have high chemical resistance, but the cost with plastic material of high chemical resistance is quite high.

Summary of the invention

In order to overcome the problem of refrigerator electric leakage, the utility model provides a kind of refrigerator lining of plastics.

The technical scheme that its technical problem that solves the utility model adopts is: comprise exterior wall; sell its health; wherein in the Food & Drink project, the cabin refrigerator is laid; closure compartment; form the inboard of an inner bag health; by plastics, there is its inherent compartment inner surface to form a barrier; to thermoforming producing zone and the insulation volume of the outer protective layer material of the outer layer protection main stor(e)y between chemistry and disposal, exterior wall is produced high density polyethylene (HDPE) and high impact polystyrene provides the chemical resistance to polyurethane foams.

It has better played the effect of insulation the utility model, lowers user's cost.

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the schematic diagram of the refrigerator lining of plastics.

The specific embodiment

With reference to Fig. 1, (1) comprise exterior wall (2), its health and Food & Drink project are wherein sold in compartment (3) in placing, liner (4) closure compartment (3) wherein insulation sale amount (5) thermoforming between polyurethane production plastic material and liner (4) and outer wall (2) injects, liner (4) has outer protection layer (6) section within it, in the face of surface, compartment (3), thereby formed such as oil and washing agent, remaining in external protection and insulation volume (5(6) main stor(e)y (7) the use chemical barrier between cleaning and disposal, refrigerator (1) the present invention includes main stor(e)y (7) high impact polystyrene, high density polyethylene (HDPE) (mixing liner (4) high density polyethylene (HDPE) produced), (3) material mixes provides HTPS and high density polyethylene (HDPE), packing material (six), the main stor(e)y (7) of stack is from manufacturing the mixture of inner bag (4), in outer field protective layer (6), this is again that first is dull and stereotyped, the table of a unit, first, by their extruder, and give the thermoforming process of its net shape.Afterwards, liner (4) (2) the polyurethane heat-insulation volume (5) that is placed on exterior wall injects.In injection process, as the freon blowing agent, for making polyurethane heat-insulation volume (5), fill, in embodiments of the present invention, main stor(e)y (7) from mixing production by high density polyethylene (HDPE), blowing agent provides chemical resistance to carry it to the adverse effect of polyurethane, and main stor(e)y (7) further remains on liner (4) dimensional stability of cooling stage, the means of the packing material that the liner (4) increased after the contained means thermoforming by high impact polystyrene and mechanical resistance reduce costs on the other hand.

Claims

1. the exterior wall (2) that forms of refrigerator (1), box (3) is sold its health and wherein Food & Drink the inside placement, inner bag (4) (3) closure compartment, the thermoforming plastic manufacture of materials has liner (4) and the outer wall (2) between protective layer (6) the insulation volume (5) that its inherent compartment inner surface (3) forms chemical attack and a main stor(e)y (7) (6) external protection and insulation volume (5) and the barrier between disposing is outer, wherein polyurethane is disposed and is injected, the main stor(e)y (7) (4) that the mixture of liner produces-Gao high impact polystyrene (HIPS)-high density polyethylene (HDPE) (HDPE)-increase-volume (three) provides the composite material of HTPS (HIPS) and high density polyethylene (HDPE) (HDPE),-and-packing material (six).
