Description

Heat insulation board for refrigeration house

Technical Field

The utility model relates to the field of construction of a refrigeration house, in particular to an insulation board for the refrigeration house.

Background

A cold storage, which is one type of refrigeration equipment. The cold storage is a constant temperature and humidity storage device which creates an environment with different outdoor temperature or humidity by manual means and is used for food, liquid, chemical engineering, medicine, vaccines, scientific experiments and other articles. The cold store is usually located near a port of transportation or a place of origin. Compared with a refrigerator, the refrigeration house has larger refrigeration area and a common refrigeration principle. The most common heat insulation material in large and medium-sized cold storages generally adopts polyurethane foam as a sandwich board of the heat insulation material.

The polyurethane foam material of the refrigeration house is easy to break when the temperature is changed severely or is at a low temperature for a long time, so that the structural stability of the refrigeration house plate is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an insulation board for a refrigeration house, which aims to solve the problem that a polyurethane foam material of the refrigeration house is easy to break when the temperature is changed severely or is at a low temperature for a long time, so that the structural stability of a refrigeration house board is poor.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a heated board for freezer, includes the mainboard layer, fixed adhesion heat preservation on the mainboard layer side surface, the surface adhesion that the mainboard layer was kept away from to the heat preservation is fixed with first waterproof layer, one side surface adhesion that the heat preservation was kept away from to the mainboard layer is fixed with the flame retardant coating, the surface adhesion in the flame retardant coating outside has the second waterproof layer.

Further, the main board layer is a color steel plate.

Further, the heat preservation includes light polyurethane board and polystyrene foam board, the fixed adhesion of the surface that is close to the mainboard layer of first waterproof layer has the polystyrene foam board, the fixed adhesion of the surface that the polystyrene foam board is close to the mainboard layer has light polyurethane board.

Further, the first waterproof layer and the second waterproof layer are both high-density polyethylene plates.

Furthermore, the flame retardant coating is fire prevention stereoplasm rock wool board.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the overall structure is more stable through the arranged main board layer, the overall structure cannot be easily broken, the manufacturing cost is low, the liquefied vapor in the refrigerating chamber can be isolated through the arranged first waterproof layer, the internal moisture of the heat insulation layer is prevented from being affected, the stability of the overall structure is influenced, a good heat insulation effect can be achieved through the arranged heat insulation layer, the energy loss is reduced, the refrigerating chamber has excellent fireproof performance through the arranged fireproof layer, the fireproof layer can be well prevented from being wetted by external moisture through the arranged second waterproof layer, so that the refrigerating chamber has excellent waterproof performance, fireproof performance, strength performance and heat insulation performance, and the refrigerating chamber is suitable for being used as a material for manufacturing the refrigerating chamber.

Fig. 1 is a schematic front sectional view of an insulation board for a refrigerator.

In the figure: 10. a main board layer; 20. a heat-insulating layer; 21. a lightweight polyurethane board; 22. a polystyrene foam board; 30. a first waterproof layer; 40. a fire barrier layer; 50. and a second waterproof layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution:

the utility model provides a heated board for freezer, includes mainboard layer 10, mainboard layer 10 one side fixed adhesion heat preservation 20 on the surface, and the surface adhesion that heat preservation 20 kept away from mainboard layer 10 is fixed with first waterproof layer 30, and the surface adhesion that heat preservation 20 was kept away from to mainboard layer 10 is fixed with flame retardant coating 40, and the surface adhesion has second waterproof layer 50 outside the flame retardant coating 40.

In addition, the main board layer 10 is a color steel plate.

The heat insulation layer 20 includes a light polyurethane plate 21 and a polystyrene foam plate 22, the polystyrene foam plate 22 is fixedly adhered to the surface of the first waterproof layer 30 close to the main board layer 10, and the light polyurethane plate 21 is fixedly adhered to the surface of the polystyrene foam plate 22 close to the main board layer 10.

Wherein, the first waterproof layer 30 and the second waterproof layer 50 are both high-density polyethylene plates.
