Organic board materials include conventional wood fiberboard, particle board, europa board, wood fiberboard, and the like. Most of the organic plates are inflammable and have poor fireproof performance and the problem of formaldehyde release. Particularly, after water absorption, the expansion of the plate body directly leads to the loss of the service performance.

Hereinafter, embodiments of the composite panel according to the present application are described in detail with reference to the accompanying drawings.
Fig. 1 is a perspective view showing a composite plate according to the present application. Fig. 2 is a sectional view showing a composite plate according to the present application.
Referring to fig. 1 and 2, a composite panel according to an embodiment of the present application includes a first panel 10, a second panel 20, and at least one connector 30.
As shown in fig. 1, the first plate 10 may include, for example, a first substrate 11, a first tensile layer 12, and a first pressure resistant layer 13 from top to bottom.
The first substrate 11 may be formed of a cement cured layer, and may include a planar outer surface 11a and an inner surface 11b disposed parallel to the outer surface 11 a.
The first stretch resistant layer 12 may include a first surface 12a and a second surface 12b disposed parallel to the first surface 12 a. The first surface 12a of the first tensile layer 12 is attached to the inner surface 11b of the first substrate 11 and disposed on the inner surface 11b of the first substrate 11 under a predetermined tensile pre-stress.
The first pressure-resistant layer 13 may be formed of a cement cured layer, and may include a first surface 13a, a second surface 13b disposed in parallel with the first surface 13a, and a plurality of first raised ribs 13c protruding outward on the second surface 13b, disposed in parallel and uniformly with each other. The first pressure resistant layer 13 is arranged with its first surface 13a against the second surface 12b of the first stretch resistant layer 12.
Therefore, the first substrate 11, the first tensile layer 12, and the first pressure resistant layer 13 are bonded together under a predetermined tensile prestress that ensures the first tensile layer 12.
The second sheet 20 may include, for example, a second substrate 21, a second tensile layer 22, and a second compressive layer 23.
The second substrate 21 may be formed of a cured layer of cement, and may include a planar outer surface 21a and an inner surface 21b disposed parallel to the outer surface 21 a.
The second tensile layer 22 may include a first surface 22a and a second surface 22b disposed parallel to the first surface 22 a. The first surface 22a of the second tensile layer 22 is attached to the inner surface 21b of the second substrate 21 and is provided on the inner surface 21b of the second substrate 21 under a predetermined tensile prestress.
The second crush zone 23 may be formed of a cement cured layer, and includes a first surface 23a, a second surface 23b arranged in parallel with the first surface 23a, and a plurality of second raised ribs 23c protruding outward on the second surface 23b and arranged in parallel and uniformly with each other. The second tensile layer 23 may be disposed with its first surface 23a conforming to the second surface 22b of the second tensile layer 22.
Therefore, the second substrate 11, the second tensile layer 22, and the second pressure resistant layer 23 are bonded together under a predetermined tensile pre-stress that ensures the second tensile layer 22.
At least one connecting member 30 may be disposed between the first plate 10 and the second plate 20 to rigidly connect the two such that the outer surface 11a of the first base plate 11 of the first plate 10 and the outer surface 21a of the second base plate 21 of the second plate 20 are parallel to each other by a first predetermined distance D1. The first predetermined distance D1 may be sized according to the design thickness of the composite plate.
The second surface 13b of the first pressure resistant layer 13 of the first plate 10 and the second surface 23b of the second pressure resistant layer 23 of the second plate 20 are disposed to face each other.
The first protrusion ribs 13c of the first pressure resistant layer 13 of the first panel 10 are disposed opposite to the second protrusion ribs 23c of the second pressure resistant layer 23 of the second panel 20 and maintained at a second predetermined distance D2 from each other. The range of the second predetermined distance D2 may be determined according to the amount of elastic deformation allowed by the first and second boards 10 and 20. In addition, a cushion pad (not shown) may be included between the first raised ribs 13c of the first pressure resistant layer 13 of the first panel 10 and the second raised ribs 23c of the second pressure resistant layer 23 of the second panel 20. The cushion may comprise a resilient material.
The predetermined tensile pre-stress of the first tensile layer 12 of the first plate 10 is equal to the predetermined tensile pre-stress of the second tensile layer 22 of the second plate 20.
Because the first and second plates 10, 20 are identical in composition and the features are located opposite each other, the first and second plates 10, 20 can be identical preforms with proper design to make the structure symmetrical. Therefore, the design of the molds for manufacturing the first and second plates 10 and 20 is reduced, and the design of the manufacturing line for manufacturing the first and second plates 10 and 20 is also simplified. Thus, after the first plate 10 and the second plate 20 are manufactured, they are connected by the connecting members, and the composite panel as described above is manufactured. In case the connecting elements are also cement cured layers, the combination of the first plate 10, the second plate 20 and the at least one connecting element 30 may be seen as a time-phased combination of cement cured layers only.
Fig. 3, 4 and 5 are sectional views showing cross sections of the composite panel shown in fig. 2.
Referring to fig. 3, according to one embodiment of the present application, the composite panel may further include a first waterproof material layer 14 and a second waterproof material layer 24.
The first waterproof material layer 14 may be formed of a waterproof material, and may include a first surface 14a and a second surface 14b opposite to the first surface 14 a. The first waterproof material layer 14 may be provided on the second surface 13b of the first pressure-resistant layer 13 and the first convex rib 13 c.
The second waterproof material layer 24 may be formed of a waterproof material, and may include a first surface 24a and a second surface 24b opposite to the first surface 24 a. A second waterproof material layer 24 may be disposed on the second surface 23b of the second pressure-resistant layer 23 and the second convex ribs 13 c.
The first waterproof material layer 14 and the second waterproof material layer 24 may include a resin composite material. Therefore, during the manufacturing process of the first and second panels 10 and 20, the water in the cement cured layer adjacent thereto can be prevented from being analyzed out, thereby avoiding any contamination or material mixing to other features in the subsequent production due to the water analysis out. Further, since the first waterproof material layer 14 and the second waterproof material layer 24 are resin composite materials, they have good adhesion to the cement cured layer and are finally integrated without peeling.
Referring to fig. 4, according to one embodiment of the present application, the composite panel may further include a first facing 15 and a second facing 25.
The first facing 15 may be disposed on the outer surface 11a of the first substrate 11 as a final facing of the first sheet 10.
The second facing 25 may be disposed on the outer surface 21a of the second substrate 21 as a final surface layer of the second board 20.
The first facing 15 and the second facing 25 may comprise the same material, for example, a resin composite. The resin composite material has a good adhesive effect on the cement cured layer. In addition, the resin composite directly contacts the mold during the manufacturing process of the first plate 10 or the second plate 20. The surface quality of the surface layer of the first board 10 or the second board 20 formed of the resin composite material is higher because the solid particle size of the resin composite material is smaller compared to the cement cured layer. Further, by using a release agent or the like, the resin composite material is more easily released than a cement cured layer, and the yield is greatly improved.
Referring to fig. 5, according to one embodiment of the present application, the composite panel may further include a first scrim layer 16 and a second scrim layer 26.
The first scrim layer 16 may be disposed on the second surface 13b of the first pressure resistant layer 13 and the first raised ribs 13 c.
A second scrim layer 26 can be disposed on the second surface 23b of the second crush layer 23 and the second raised ribs 23 c.
Fig. 6 is a schematic plan view showing an arrangement of raised ribs and vertical ribs of a composite panel according to the present application. Fig. 7 is a schematic plan view illustrating one embodiment of a connector of a composite plate according to the present application. Fig. 8 is a schematic plan view illustrating another embodiment of a connector of a composite plate according to the present application.
Referring to fig. 6, according to an embodiment of the present application, the composite plate may further include a plurality of first vertical ribs 13d and a plurality of second vertical ribs 23 d.
The plurality of first vertical ribs 13d may be perpendicular to the first raised ribs 13c and uniformly disposed between any two of the first raised ribs 13 c.
The plurality of second vertical ribs 23d may be perpendicular to the second raised ribs 23c and uniformly disposed between any two of the second raised ribs 23 c.
The plurality of first raised ribs 13c and the plurality of first vertical ribs 13d may form a lattice on the first pressure resistant layer 13, the plurality of second raised ribs 23c and the plurality of second vertical ribs 23d form a lattice on the second pressure resistant layer 23, and the lattice on the first pressure resistant layer 13 and the lattice on the second pressure resistant layer 23 face each other.
Fig. 6 shows a case where a plurality of first raised ribs 13c and a plurality of first vertical ribs 13d are provided on the first pressure resistant layer 13 or a plurality of second raised ribs 23c and a plurality of second vertical ribs 23d are provided on the second pressure resistant layer 23 vertically and horizontally in the drawing. However, the composite plate according to the present application is not limited thereto, and as will be appreciated by those skilled in the art, the plurality of first raised ribs 13c and the plurality of first vertical ribs 13d on the first compressive layer 13 or the plurality of second raised ribs 23c and the plurality of second vertical ribs 23d on the second compressive layer 23 may be arranged in any orientation with being perpendicular to each other, for example, rotated at an angle of 45 degrees in the orientation shown in fig. 5 to be a diamond-shaped grid.
Referring to fig. 7, the at least one connecting member 30 may be a frame disposed in one direction, and may be formed of a cement cured layer. In addition, at least one connector 30 may also be combined with the arrangement of the first and second raised ribs 13c and 23 c. That is, a frame may be disposed between the first and second protrusion ribs 13c and 23 c. Even the at least one connector 30 may be a first raised rib 13c and a second raised rib 23c provided on the edge of the composite panel to be coupled to each other.
Referring to fig. 8, the at least one connecting member 30 may be a frame disposed at the periphery, and may be formed of a cement cured layer. In addition, a horizontally disposed frame may also be combined with the arrangement of the first and second vertical ribs 13d and 23 d. That is, the horizontally disposed frame may be the first and second vertical ribs 13d and 23d disposed on the upper and lower edges of the composite panel.
Further, the at least one connector 30 may be any other type of connector, such as cement nails, metal connectors, and the like.
Referring back to fig. 1, the gap between the first plate 10 and the second plate 20 may be optionally filled with a filler 70. The filler 70 may include a lightweight material, an acoustic panel, or an insulation panel. The lightweight material may comprise one of foam plastic, bamboo sawdust, perlite, foamed concrete, or any combination of two or more thereof. The sound insulation board or the heat insulation board can be properly selected on the basis of the known technology in the field according to the design requirements of the composite board. Further, it is noted that even without the filler 70, the space between the first panel 10 and the second panel 20 has superior sound insulation and thermal insulation properties by itself.
In a preferred embodiment, the first and second raised ribs 13c and 23c may include an unsaturated resin.
In a preferred embodiment, the first and second vertical ribs 13d and 23d may include an unsaturated resin.
In the case of adding an unsaturated resin, the first and second raised ribs 13c and 23c and/or the first and second vertical ribs 13d and 23d will decrease the hardness and brittleness. Therefore, it is easy to embed or screw in a metal member, for example, a thread insert 40 (see fig. 9) which will be described in detail below.
In a preferred embodiment, the first tensile layer 12 and the second tensile layer 22 may comprise wire mesh, mesh cloth, plastic perforated sheet, or metal perforated sheet. The wire mesh may comprise a wire mesh. The scrim may comprise glass fibers. The metal orifice plate can be, for example, a common steel orifice plate, a high manganese steel orifice plate, or the like. The plastic orifice plate may be, for example, a flame retardant plastic orifice plate. Those skilled in the art can appropriately select in design according to the application use of the composite panel.
In a preferred embodiment, the cement cured layer comprises one of a rapid hardening early strength sulphoaluminate cement, an aluminoferrite cement, a portland cement, a magnesium oxychloride cement, a magnesium phosphate cement, an aluminous cement, or a combination of any two or more thereof. However, the embodiments of the present application are not limited thereto, and any other types of cement and cement-cured layers may be selected, and a retarder and a waterproofing agent may be added to the cement-cured layers. The set retarder in the set layer of cement may include, for example, lignosulfonate and derivatives thereof, low molecular weight cellulose and derivatives thereof, hydroxycarboxylic acid (salts), organophosphonic acid (salts), boric acid (salts), composites, and the like. The cement waterproofing agent may include, for example, inorganic compounds and organic compounds, and the inorganic compounds may include ferric chloride, modified silicon, zirconium compounds, and the like. The organic compounds may include fatty acids and salts thereof, silicone surfactants (e.g., sodium methyl silanol, sodium ethyl silanol, polyethyl hydroxy siloxane), paraffin, bitumen, rubber, and water-soluble resin emulsions. The silicone zirconium can be used for a cement-based infiltration crystallization waterproof system. Those skilled in the art can make appropriate selections according to actual needs in design.

One of the great disadvantages of cement pre-forms is the difficulty of driving in the nail and the poor nail-holding power. In order to solve such a technical problem, according to the embodiments of the present application, the composite panel has unsaturated resin added to the raised ribs or the vertical ribs at the positions where nails (including bolts and nuts) are required for connection, that is, as described above. The unsaturated resin is a viscous liquid obtained by dissolving a linear polymer compound containing unsaturated dibasic acid or dihydric alcohol, which is obtained by condensation polymerization of dibasic acid and dihydric alcohol, in a monomer (usually styrene). The addition of unsaturated resins to the cement cured layer can reduce brittleness, enhance toughness and flexibility. By adding unsaturated resin, the solidified layer of cement can be screwed into the self-tapping screw after solidification, so that the problems of difficult nail penetration and poor nail holding power of the composite board are solved.
As shown in fig. 9, the composite plate may also include one or more thread sockets 40 according to one embodiment of the present application. One or more thread sockets 40 may be embedded at positions corresponding to the first and second raised ribs 13c and 23 c.
An outer end face 41 of one or more thread sockets 40 of the composite plate may be coplanar with outer surface 11a of first substrate 11 or outer surface 21a of second substrate 21. Of course, the outer end face 41 of one or more thread inserts 40 may be higher or lower than the outer surface 11a of first substrate 11 or the outer surface 21a of second substrate 21, depending on the application of the composite plate.
As shown in fig. 11 and 12, the outer wall surface of one or more thread inserts 40 of the composite plate is provided with self-tapping threads 42. In the case where the outer wall surface of one or more of the thread inserts 40 of the composite panel is provided with self-tapping threads 42, the thread insert 40 may be embedded in the composite panel or may be screwed into the composite panel by the self-tapping threads 42. That is, in this case, the depth of the thread socket 40 in the composite plate is adjustable. Additionally, as shown in FIG. 9, internal threads within the threaded socket 40 may be used to screw in to secure any object that needs to be secured to the composite panel, such as a television, air conditioner, switch base, etc.
In the absence of the threaded socket 40, where it is desired to secure objects to the composite panel for various purposes, as shown in fig. 10, small holes may also be temporarily opened at the locations of the raised or vertical ribs of the composite panel and screwed into the composite panel with self-tapping screws. This also benefits from the addition of an appropriate amount of unsaturated resin to the cement cured layer at such locations.
