Description

Technical Field

[0001] The invention relates to the technical field of cold storage insulation boards, and in particular to an insulation board used for cold storage insulation. Background Art

[0002] A cold storage is a building that uses artificial refrigeration to allow a very fixed space to reach a specified temperature. This is also very convenient for storing items. The cold storage insulation board is a commonly used engineering construction material. The cold storage insulation board can ensure that the temperature loss in the cold storage is reduced, greatly reducing the energy consumption of the cold storage. It is one of the important devices for cold storage insulation and energy saving.

[0003] After searching, the applicant found that a Chinese patent disclosed "a composite insulation board for cold storage walls", and its publication (announcement) number is "CN210062239U". This patent mainly uses an eight-shaped rubber block to press down on the aluminum foil layer to open the aluminum foil layer to both sides. The glass wool layer can maintain good thermal insulation performance at high and low temperatures and has good sound absorption performance. It has good sound absorption effect on various sound waves and noises. The polyurethane foam layer has a good thermal insulation effect, and also has multiple effects such as heat insulation, sound absorption, and waterproofing. It is an environmentally friendly, energy-saving and easy-to-use material. The polyurethane foam layer is placed on the first plywood and the second plywood. The adhesive setting of the fixing block inserted into the groove opened on the polyurethane foam layer makes the polyurethane foam layer more firmly fixed. However, during the use of traditional cold storage insulation boards, the block cold storage insulation boards need to be spliced ​​and fixed to ensure the overall insulation effect of the cold storage. The splicing between traditional cold storage insulation boards does not have any connecting fixings to fix the spliced ​​cold storage insulation boards. They are all fixed by gluing. Due to the limitation of the validity period of the adhesive, the firmness of the glue may be reduced, which will affect the stability and connection strength of the cold storage insulation board splicing process, and may even affect the safety of the entire cold storage insulation construction process.
