Description

Technical Field

[0001] The utility model belongs to the technical field of rigid foamed polyurethane boards, and particularly relates to an improved rigid foamed polyurethane board. Background Art

[0002] Rigid polyurethane foam, also known as rigid polyurethane foam, is second only to soft polyurethane foam in terms of usage in polyurethane products. Most rigid polyurethane foams have a closed-cell structure and offer excellent properties such as good thermal insulation, light weight, high specific strength, and easy construction. They also offer sound insulation, shock absorption, electrical insulation, and resistance to heat, cold, and solvents. They are widely used in refrigerator and freezer insulation, cold storage, refrigerated trucks, and other insulation materials, as well as in buildings, storage tanks, and pipelines. Smaller amounts are used in non-insulating applications, such as wood imitation and packaging. Generally speaking, lower-density rigid polyurethane foams are primarily used as thermal insulation (heat preservation), while higher-density rigid polyurethane foams can be used as structural materials (imitation wood).

[0003] When using existing rigid foamed polyurethane boards, they are usually directly glued and fixed to the position where they need to be used. However, after long-term use, the polyurethane boards are prone to detachment from the installation position and are prone to breakage when hit, resulting in poor performance of the polyurethane boards. In addition, the polyurethane boards are inconvenient to connect with adjacent polyurethane boards. Therefore, we need to upgrade and transform the existing technology. Utility Model Content
