Description

Manufacturing method of a PS board for balcony shelving, and a PS board for balcony shelving produced by the same The present invention relates to a method for manufacturing a PS board for a balcony shelf and a PS board for a balcony shelf manufactured by the said method. More specifically, the invention relates to a method for manufacturing a PS board for a balcony shelf that is used as a board material for a shelf manufactured in an assembly or detachable manner for a shelf used to place or display items on a balcony of an apartment or building, and has the characteristics of being lightweight, making it convenient to transport and handle, not rotting even in environments with condensation or high humidity, having a long lifespan so that it can be used semi-permanently, having excellent flame retardancy so that it has excellent resistance to fire, and also having excellent resistance to mold and stains. In general, balconies exist in residential apartments, mixed-use buildings, and commercial buildings. Shelves are installed in a modular fashion on the balconies to store various items, and boards for stacking items are installed on the shelves using anchors or screws. At this time, the above shelf boards are often manufactured using wood, plastic, glass, or metal, but they are frequently made using wood for reasons such as cost-effectiveness and structural stability. For these wooden shelves, MDF, which is typically manufactured using sawdust, or PB panels, made by grinding wood, are commonly used. In particular, for apartments constructed by public corporations such as LH or SH, MDF or PB panels are frequently used to ensure economic efficiency. However, in the case of MDF or PB boards as described above, balconies in apartments and the like are separated from the outside by a single concrete wall, creating an environment where condensation or moisture is very likely to form inside, and there is a problem that the MDF or PB easily rots due to condensation or moisture. As such, if the balcony shelves rot due to condensation or moisture, mold and odors develop, which can be very harmful to the human body and are also very unsightly, leading to complaints. Therefore, there is a need to develop technology capable of solving the existing problems of such balcony shelves. In particular, there is a significant need to develop balcony shelf panels that can be used semi-permanently by overcoming the short lifespan of existing MDF or PB products caused by moisture or condensation, while also offering excellent economic efficiency with no significant price difference and possessing the characteristic of not easily catching fire. If we look at the conventional technology related to this, First, Korean Published Patent No. 10-2016-0116363 discloses a method for manufacturing exterior panels for building structures, and specifically, a method for manufacturing expanded polystyrene panels formed by compressing and melting polystyrene injected with a hydrocarbon gas such as pentane or butane while applying steam, comprising: a polystyrene aging step in which the polystyrene injected with the hydrocarbon gas is aged in a natural state for 4 to 8 hours to adjust the amount of hydrocarbon gas to 40 to 50%; a polystyrene filling step in which the aged polystyrene is filled into a mold and the density of the filled polystyrene is adjusted; and a first compression step in which steam is applied to the polystyrene and press-compressed to have a density corresponding to 10 to 20 kg/㎥. A method for manufacturing an exterior panel for a building structure using high-density polystyrene is disclosed, wherein a secondary compression step is performed by applying steam to the polystyrene and press-compressing it to achieve a density of 38 to 44 kg/m³, and the polystyrene into which gas is injected is compressed to produce expanded polystyrene, thereby lowering the degree of expansion of the polystyrene to enable density improvement and uniformity, while also improving strength so that it can be used as a lightweight exterior panel for a building. However, the exterior panels for building structures according to this technology are mainly related to the manufacture of expanded polystyrene panels for insulation construction of buildings, and have little relevance to shelf panels for use in interior balconies of buildings, and the panels manufactured by this technology have limitations in that they cannot be used as shelf panels because they are weak in terms of strength and toughness. In addition, Korean published patent No. 10-2009-0061407 relates to a composite panel manufactured using natural stone, and discloses a natural stone composite panel in which a plate made of aluminum, iron, copper, tin, zinc, etc., either alone or in a plated or alloyed state, and other metal plates are adhered to the back side of a thinly sliced natural stone, and a substrate in which organic materials such as polyvinyl chloride, polyethylene, polypropy
