Novel cold storage board

Abstract

The invention discloses a novel cold storage board. The novel cold storage board comprises a box-shaped panel. An opening is formed in the upper portion of the box-shaped panel, the opening is coveredwith a sealing panel, and the size of the opening corresponds to the size of the sealing panel. The sealing panel is connected with the box-shaped panel in a sealed mode, and wing edges are arrangedon the periphery the box-shaped panel. A vacuum insulation board is arranged on the lower surface of the sealing panel, and a vacuum insulation board is arranged on the inner bottom surface of the box-shaped panel. A filler layer is arranged between the two vacuum insulation boards in the box-shaped panel, and the filler layer is a rock wool insulating layer. The lower surface of the sealing paneland the vacuum insulation board are bonded by a flame-retardant polyurethane foaming agent, and the bottom surface of the box-shaped panel and the vacuum insulation board are bonded by the flame-retardant polyurethane foaming agent. Concave-convex reinforcing ribs are separately arranged on the outer bottom surface of the box-shaped panel and the upper surface of the sealing panel. The novel coldstorage board has good thickness of the thermal insulating layer and excellent heat preservation and thermal insulation effects; high density, strong endurance, good heat preservation and fireproof effects and strong overall tensile strength are achieved; and the novel cold storage board can be used in the field of cold storages, board rooms and the like.

Description

technical field [0001] The invention belongs to the technical field of boards used in cold storage buildings, and in particular relates to a novel cold storage board. Background technique [0002] At present, cold storage panels have become the mainstream panels used in cold storage buildings, energy saving and heat preservation, and easy installation; several important factors of cold storage panels include the density, heat preservation, and endurance of cold storage panels; because most of the existing cold storage panels are foam sandwiches Board, if this kind of foam sandwich cold storage insulation board wants to have a high density, then the foaming in the board needs to increase the amount of polyurethane, which will increase the thermal conductivity of the cold storage board at the same time, so that the insulation performance of the cold storage board will decrease and the board's The cost increases, and if the foaming density is too low, the durability of the cold...

[0002] At present, cold storage panels have become the mainstream panels used in cold storage buildings, energy saving and heat preservation, and easy installation; several important factors of cold storage panels include the density, heat preservation, and endurance of cold storage panels; because most of the existing cold storage panels are foam sandwiches Board, if this kind of foam sandwich cold storage insulation board wants to have a high density, then the foaming in the board needs to increase the amount of polyurethane, which will increase the thermal conductivity of the cold storage board at the same time, so that the insulation performance of the cold storage board will decrease and the board's The cost increases, and if the foaming density is too low, the durability of the cold storage board will decrease; in summary, the existing cold storage board still has poor strength, poor air tightness, poor flame retardancy, and poor thermal insulation. Disadvantages such as poor effect
