Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of board material, especially a novel calcium silicate board. BACKGROUND

[0002] Calcium silicate boards are widely used in residential and commercial buildings for constructing fire-resistant walls and partitions. In addition, their moisture resistance and sound absorption properties make them suitable for various indoor applications, such as walls, partitions, and ceilings. This is particularly beneficial in high-humidity areas. Furthermore, their smooth and stable surface makes them suitable substrates for flooring and wall tiles, ensuring a level and uniform base during installation.

[0003] However, calcium silicate boards are known for their brittleness, especially if they are thin or subjected to impact or stress. This brittleness can lead to cracking or breaking if mishandled during installation or use. Moreover, although calcium silicate boards are moisture-resistant, if not properly sealed or exposed to moisture and temperature changes for extended periods, calcium silicate boards can further absorb moisture over time, affecting the lifespan of the calcium silicate board.

[0015] As shown in the structure schematic view of the novel calcium silicate plate provided by the utility model, the novel calcium silicate plate comprises a composite layer 10, a decorative layer 20 arranged on one side of the composite layer 10, and a wear-resistant layer 30 arranged on the side of the decorative layer 20 away from the composite layer 10. Figure 1 The base building plate further comprises other functional modules such as assembly components and the like, which should be the technology known to those skilled in the art, and will not be described in detail here.

[0017] The calcium silicate core layer 11 is made of calcium silicate, silicon dioxide and aluminum oxide, wherein the calcium silicate core layer 11 is mainly made of calcium silicate. Since calcium silicate is a natural material, it is non-toxic and does not contain formaldehyde, so the safety of the calcium silicate core layer 11 is improved, and it has good sound insulation function. In addition, since the calcium silicate material itself has good fireproof performance, combined with the use of the fiber layer 12, the fire resistance limit of the plate can be further improved, so that the structure remains stable in the case of fire. In this embodiment, the thickness of the calcium silicate core layer 11 is 6mm.

[0018] The fiber layer 12 comprises a plurality of fibers 121 arranged in a staggered manner. The fibers 121 are at least one of glass fibers, cellulose fibers, and carbon fibers. The fiber layer 12 and the fibers 121 are all prior art, wherein the fiber layer 12 is a porous network structure, and the fiber layer accounts for 5-20 wt% of the core layer 11, which proportion can ensure that the plate maintains proper flexibility while enhancing its impact resistance and structural stability. In the present embodiment, the fiber layer 12 has a surface area of at least 10 m / g, a porosity of at least 20%, a fiber roughness value of 6-30 mg / 100 m, a fiber diameter of 3-50 microns, and a fiber length-diameter ratio of 135-1000:1, all of which are used to improve the bonding effect between the fiber layer 12 and the composite layer 10.

[0019] The adhesive layer 13 is made of a polymer adhesive, which can be any one or a combination of vinyl, polyvinyl chloride (PVC), polyethylene (PE), polyurethane (PU), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polytrimethyl terephthalate (PTT), polyethylene naphthalate (PEN), polyethylene terephthalate glycol (PETg), and / or polypropylene (PP). The adhesive layer 13 is used to form an integral whole of the fiber layer 12 and the calcium silicate core layer 11, and is a prior art which will not be described here.

[0020] The decorative layer 20 is arranged on one side of the composite layer 10, and has a thickness of 1 mm. The decorative layer 20 can be any one of a printed pattern and a textured pattern, and is used to improve the aesthetics of the composite layer 10. The decorative layer 20 is a prior art which will not be described here.

[0021] The wear-resistant layer 30 is arranged on the side of the decorative layer 20 away from the composite layer 10, and improves the wear resistance of the decorative layer 20, facilitating the use of the novel calcium silicate plate. The wear-resistant layer 30 has a thickness of 0.6 mm, and is a prior art which will not be described here.

[0022] Compared with the prior art, the novel calcium silicate plate provided by the utility model is combined with the acid calcium core layer 11 and the fiber layer 12 to form an integral whole through the adhesive layer 13 in the composite layer 10, wherein the fiber layer 12 comprises a plurality of staggered fibers 121, the fiber layer 122 is a porous network structure, the fiber layer 122 accounts for 5-20wt% of the calcium silicate core layer, the fiber layer 12 and the acid calcium core layer 11 form an interconnected structure, the fiber layer 12 serves to enhance the strength and flexibility of the calcium silicate core layer 11, the fiber layer 12 can reduce the water absorption of the plate and improve the durability of the plate in a humid environment. It can be seen that the novel calcium silicate plate improves the strength, flexibility, impact resistance and durability of the plate.
