The porous layer is a sheet of material selected from the group consisting of polyethylene, polypropylene, polystyrene, and polyvinyl chloride having a plurality of pores including two spaced apart sides. The solid layers are respectively formed on the sides of the porous layer and coextruded with the porous layer, and each of the solid layers is a layer of material selected from the group consisting of polyethylene, polypropylene, polystyrene, and polyvinyl chloride. The sheets of the holes, each of which has a thickness smaller than the thickness of the porous layer. The plate is designed by the above structure, and has the advantages of light weight, low cost and convenient construction.

Description

Plate

The present invention relates to a sheet, in particular to a sheet suitable for use in the construction and decoration industries.

In the past, the building formwork, floor and partition panels used in the construction industry and the decoration industry were mostly made of wood, but they were heavy, low in strength, thermal expansion and contraction, non-fireproof and waterproof, easy to grow insects and damp and rot. Disadvantages, and short service life can not be reused many times, especially damage to forest resources causing environmental damage, so there are many problems to be solved. Therefore, some manufacturers use steel plates instead of wood to make building formwork, or use single or multi-layer solid plastic plates instead of wood to make floors and partitions, which can not only be fireproof, not rot, not deformed, but also It has improved strength and can be reused, but it still has the disadvantages of heavy weight and high cost, so the design still needs to be improved. The present invention provides a sheet made of a plastic material that can reduce weight and reduce cost to provide consumers with a choice.

Accordingly, it is an object of the present invention to provide a sheet material that overcomes at least one of the disadvantages of the prior art.

Thus, the novel sheet comprises a porous layer and two solid layers. The porous layer is a sheet of material selected from the group consisting of polyethylene, polypropylene, polystyrene, and polyvinyl chloride having a plurality of pores including two spaced apart sides. The solid layers are respectively formed on the sides of the porous layer and coextruded with the porous layer, and each of the solid layers is a layer of material selected from the group consisting of polyethylene, polypropylene, polystyrene, and polyvinyl chloride. The sheets of the holes, each of which has a thickness smaller than the thickness of the porous layer.

Referring to FIG. 1 and FIG. 2, an embodiment of the present invention is applicable to architectural templates, floors and partitions of the construction industry and the decoration industry, etc. The sheet 1 is a layered structure comprising a porous layer 2, and two A solid layer 3.

In terms of the structure of the porous layer 2 and the solid layers 3, the porous layer 2 is a layer of material selected from the group consisting of polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC). And a sheet having a plurality of pores, the porous layer 2 comprising two spaced side faces 21. It is to be noted that the porous layer 2 is a foamed foamed layer which can be formed by chemical foaming or It is made by physical foaming, and its foaming density can be adjusted according to the required strength and cost. The solid layers 3 are respectively formed on the side faces 21 of the porous layer 2, and each of the solid layers 3 is made of a material selected from the group consisting of polyethylene (PE), polypropylene (PP), and polystyrene (PS). Polyvinyl chloride (PVC) and non-porous sheets, each of which includes a surface 31 spaced apart from the porous layer 2 and flattened.

Further, in view of the size of the porous layer 2 and the solid layers 3, the thicknesses of the solid layers 3 are equal to each other, and the thickness of each of the solid layers 3 is smaller than the thickness of the porous layer 2, of course, The thickness of the solid layer 3 may not be equal. In the present embodiment, the thickness of the sheet material 1 is 5-20 mm, preferably 9-15 mm, and the thickness of the porous layer 2 and the solid layer 3 is The ratio is not particularly limited, and the thickness of the sheet 1 is 15 mm. In this case, the thickness of the upper middle and lower sheets in FIG. 2 may be 0.5:14:0.5, 1:13:1, 2: The design of 11:2, 3:9:3, etc., the thicker the thickness of the porous layer 2 in the middle, the lower the cost. Further, the solid layers 3 may be made identical or different colors to each other as needed, and the color of the porous layer 2 may be the same or different.

Referring to Fig. 3, in the manufacture, the sheet 1 is made of two coextrusion extruders 4, and is made of polyethylene (PE), polypropylene (PP), polystyrene (PS), and polyvinyl chloride (PVC). A new plastic material or a general-purpose plastic recycled material is used for co-extruding the foaming molding, thereby forming a three-layer sheet in which the porous layer 2 is in the middle and the solid layers 3 are on both sides, and the three layers are formed. The material of the sheet is the same, the compatibility is high, and the co-extrusion is integrated into one body, and the problem of peeling off does not occur.

In summary, the novel sheet material 1 is a three-layer co-extruded foaming sheet, and the porous layer 2 can reduce the overall weight. The solid layer 3 can make the overall surface flat and increase in strength, so the above structure is Designed to prevent flames, water, decay, insects, no deformation, no delamination, and light weight, high strength, low cost, flat surface, easy construction and reusable, and Any length, width, hardness and thickness can be customized, which is quite convenient and practical, so it can achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
