Description

Technical Field

[0001] The utility model relates to the technical field of building plates, in particular to a flame-retardant color steel plate. Background Art

[0002] Color steel plates are widely used in industries such as construction, home appliances, and transportation. In the construction industry, they are mainly used for roofs, walls, and doors of industrial and commercial buildings such as steel structure factories, airports, warehouses, and cold storage. Civilian buildings rarely use color steel plates. Generally, buildings such as factories that use color steel plates have relatively high structural strength requirements, and at the same time, the buildings need to have functions such as beauty and fire prevention. The structural strength of ordinary color steel plates is only reflected in the steel plates, and they do not have functions such as fire retardancy and heat preservation. Therefore, in order to increase the thermal insulation effect, color steel plates are generally used to sandwich plastic foam and other insulation materials between two layers of steel plates to achieve the thermal insulation effect. However, this structural strength is poor, and the internal filling material is a flammable material, which makes this steel plate prone to fire. In response to the above problems, people invented patent number: 202022171533.X, which discloses a heat-insulating flame-retardant color steel plate, a first color steel plate, an insulation layer and a second color steel plate, the first color steel plate and the second color steel plate are stacked in parallel, and metal plates are provided at the ends of the first color steel plate and the second color steel plate, and the metal plates are seamlessly connected to the first steel plate and the second steel plate to form a fully enclosed metal shell; the left end of the metal shell is provided with a mother groove, and the right end of the metal shell is provided with a sub-groove; the mother grooves of the two metal shells and the racks of the sub-groove are engaged by meshing; the insulation layer is provided inside the metal shell, and the side of the metal shell away from the insulation layer is plated with a corrosion-resistant layer, and the side of the corrosion-resistant layer away from the insulation layer is coated with a corrosion-resistant coating, and the side of the corrosion-resistant coating away from the insulation layer is composited with a fire-retardant coating. The heat-insulating flame-retardant color steel plate of the utility model scheme improves the thermal insulation effect of the color steel plate while also making the color steel plate have excellent flame retardant properties. However, the flame-retardant color steel plate still has the following problems: 1.
