Description

Technical Field

[0001] The invention belongs to the technical field of board materials, in particular to a flexible building board material. Background Art

[0002] Panels are flat rectangular blocks of building materials made into standard sizes and used in the construction industry as wall, ceiling or floor components.

[0003] At present, traditional boards are rigid and only suitable for flat surfaces. This limits the application of such building boards and makes it difficult to adhere these boards to curved surfaces. In order to improve the flexibility of the boards, non-environmentally friendly materials such as plastics are usually added. Although adding non-environmentally friendly materials such as plastics can improve the flexibility of the boards, this is contrary to the concept of sustainable development and environmental protection. Summary of the invention

[0004] In view of this, the present invention provides a flexible building board that can be applied to curved surfaces to meet industrial needs.

[0005] A flexible building board comprises a composite core layer and a decorative layer arranged on one side of the composite core layer. The composite core layer comprises a first elastic sublayer, a second elastic sublayer arranged on one side of the first elastic sublayer, and at least one fiber layer arranged between the first elastic sublayer and the second elastic sublayer. Each fiber layer can be arranged on either the first elastic sublayer or the second elastic sublayer. The first elastic sublayer and the second elastic sublayer both comprise dolomite, calcium carbonate, and polyester. The decorative layer is arranged on the side of the first elastic sublayer facing away from the second elastic sublayer, and the toughness of the first elastic sublayer is greater than that of the second elastic sublayer, so as to achieve the bending of the flexible building board.

[0006] Furthermore, the first elastic sublayer and the second elastic sublayer both include silicon dioxide, silicate, iron oxide, oleamide, and barium sulfate. The content of dolomite is 78.8%, the content of calcium carbonate is 13.9%, the content of polyester is 3.8%, the content of silicon dioxide is 2%, the content of silicate is 1%, the content of iron oxide is 0.2%, the content of oleamide is 0.1%, and the content of barium sulfate is 0.1%.

[0007] Furthermore, the flexible building board further comprises an adhesive layer arranged on a side of the composite core layer facing away from the decorative layer.

[0008] Furthermore, the composite core layer also includes at least one fiber layer, which can be arranged in the first elastic sublayer and the second elastic sublayer. The fiber layer includes a plurality of fibers, which are overlapped or staggered, and the fibers are any one of glass fibers and carbon fibers.

[0009] Furthermore, the surface area of ​​the fiber layer is at least 10 m2 / g, and the porosity of the fiber layer is at least 20%.

[0010] Furthermore, the fiber has an arithmetic mean roughness of 6 to 30 microns, a diameter of 3 to 50 microns, and an aspect ratio of 135 to 1000:1.

[0011] Furthermore, the flexible building board also includes a connector arranged at the edge of the composite core layer, and the connector can be any one of a hinge and a flexible joint.

[0012] Furthermore, the composite core layer and the decorative layer have the same color.

[0013] Furthermore, the flexible building board also includes a transparent coating layer arranged on one side of the decorative layer, and the transparent coating layer is made of any one of polyurethane or polyurethane.

[0014] Furthermore, a printed pattern is arranged on the decorative layer, and an embossing is arranged on the transparent coating layer. When the transparent coating layer is arranged on the decorative layer, the embossing and the printed pattern correspond to each other.

[0015] Compared with the prior art, the flexible building board provided by the present invention realizes the bending of the board through the composite core layer. The composite core layer includes a first elastic sublayer and a second elastic sublayer arranged on one side of the first elastic sublayer. The toughness of the first elastic sublayer is greater than the toughness of the second elastic sublayer, that is, the inner and outer sides of the composite core layer have different flexibility values, so as to realize the bending of the flexible building board. In addition, each layer of the fiber layer can be arranged on any one of the first elastic sublayer and the second elastic sublayer, and the fiber layer improves the flexibility of the first elastic sublayer and the second elastic sublayer to facilitate the bending of the flexible building board. It can be seen from this that the flexible building board can be installed on a curved surface to meet different usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
