Abstract

(57) [Problem] To provide a high value-added useful material such as a building material and a furniture material by increasing the strength and rigidity of a polystyrene foam plate. SOLUTION: A polyvinyl chloride-based styrofoam plate characterized in that a metal mesh plate is integrated into the inside thereof during foam molding to increase the strength.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement in a polyvinyl chloride-based polystyrene foam plate.

[0002]

[Prior art]

 Generally, a polyvinyl chloride-based styrofoam plate is injection molded by directly extruding polyvinyl chloride.

[0003]

[Problems to be solved by the invention]

 Since the above-mentioned styrofoam plate does not contain any other material in its interior, its hardness and strength are extremely low. For this reason, it is easily deformed and is used merely as a filling or cushioning material, and cannot be used as an interior material, partition, wall material, etc. of a building. Furthermore, it is impossible to use it as high value-added materials such as furniture.

[0004]

[Means to solve the problem]

 In order to address the above problems, the present invention provides a metal plate having a large number of holes punched therein during foam molding, a metal mesh plate cut by a press, and a knitted plate formed by knitting a metal wire. A polystyrene foamed styrene plate was devised, which is characterized by increasing strength by integrating a metal net plate.

Embodiment

 In the first embodiment of the present invention shown in FIG. 1, a polyvinyl chloride-based styrofoam plate is formed by integrally forming a flat metal mesh plate 11 inside a main body 10 during foam molding. The metal mesh plate 11 is made of a plate material or a wire material such as iron, stainless steel, or aluminum having a high hardness. It is used in the form of a net plate or a flat net plate formed by knitting a wire. Regardless of the form of the metal mesh plate used, the expanded styrol plate 1 formed by integrating the metal mesh plate inside the metal mesh plate has an increased strength and hardness and is less likely to be deformed. It will be a high value-added material for high-end interior materials such as decorative wall materials and furniture materials.

The polyvinyl chloride-based styrofoam plate 1 according to the present invention has a certain width at the time of molding, but when used as a building material, it must be joined in parallel to increase the width. In this case, as shown in FIG. 3, a recess 101 and a projection 102 are provided on both left and right sides of the styrofoam plate main body 10 so as to be fitted therein, and the two main bodies 10 can be combined to increase the width. . Further, in order to increase the strength and rigidity of the Styrofoam plate main body 10 and to prevent vertical and horizontal bending due to the widening thereof, at least one groove 103 is provided on one side of the main body 10 as shown in FIG. Is desirable.

In the second embodiment of the present invention shown in FIG. 2, a polyvinyl chloride-based styrofoam plate 1 ′ is integrally formed by inserting a corrugated metal net plate 11 ′ inside a main body 10 ′ during foam molding. It was formed by chemical molding. In this case, the corrugated metal mesh plate 11 'is made of a high-rigidity, high-strength wire of iron, stainless steel or aluminum. A net plate formed by knitting a cut or elongated net plate or a wire rod is formed into a corrugated shape, and then integrally formed with the Styrofoam plate main body 10 '. The basic structure of the styrofoam body 10 'is the same as that of the styrofoam plate body 10 of the first embodiment, and therefore will not be particularly described. In some cases, a hard polyvinyl chloride foamed styrofoam plate 12 is added to the surface of the plate body and integrally molded with the plate body 10 ′, thereby providing a high value-added material useful as a building material or furniture material.

[0008]

[Effect of the invention]

 The polyvinyl chloride foamed polystyrene plate according to the present invention is useful as a building material or furniture material by increasing its hardness and preventing deformation. Lowering the cost can lower the manufacturing cost.
