Description

Fire Prevention Panel and Manufacturing Method Thereof The present invention relates to a flame-retardant panel and a method for manufacturing the same, and more specifically, to a flame-retardant panel and a method for manufacturing the same that can enhance durability along with improved flame-retardant performance. Generally, various building materials, such as interior and exterior materials, are used in structures like houses and buildings. These materials are manufactured by processing or molding in various ways using materials such as wood, synthetic resin, or metal. Panel-type materials are mostly used for interior finishing materials and materials, including walls, ceilings, and flooring, as well as for various furniture items such as doors and built-in furniture. Currently, most panel-type materials are primarily wood-based panels, with examples including solid wood, medium-density fiberboard (MDF), particleboard (PB), melamine board, plywood, and reinforced wood. In addition, wood-based panels such as the aforementioned medium-density fiberboard (MDF) or particleboard (PB) are the most widely adopted and used because they are inexpensive and can be mass-produced, and they can also provide a luxurious feel when finished with adhesive sheets. However, wood-based panels, which are widely used as conventional building materials, have disadvantages such as being very susceptible to flames due to their material properties, easily burning, or generating smoke during a fire. In the event of a fire, they can quickly develop into a large-scale fire or increase damage to human life and property. In particular, if sheets are attached, the rate of hazardous substance generation increases, which can cause even more serious problems. In addition, conventional wood-based panels, such as medium-density fiberboard (MDF) or particleboard (PB), have the disadvantage of being susceptible to moisture because wood is the main component, and can increase smoke generation in the event of a fire. Accordingly, to overcome the disadvantage of fire vulnerability of such wood-based panels, flame-retardant panels with flame-retardant properties are being proposed and disclosed. For the manufacture of flame-retardant panels, methods such as bonding films and other materials to flame-retardant materials (magnesium, gypsum), coating or laminating inorganic materials such as flame-retardant resins or glass fibers mixed onto materials (MDF, PB, etc.) or flame-retardant materials (magnesium, gypsum), bonding flame-retardant sheets to materials (MDF, PB, etc.) or bonding a film on top thereof, and bonding general low-pressure melamine sheets (LPM) to materials (MDF, PB, etc.) and coating a flame-retardant UV coating agent thereon are being used. In addition, the above-mentioned flame-retardant panel is a building material and falls under the category of fire-related flame-retardant items, and thus can be said to be related to the Fire Prevention Act. It must be a product that passes the test items specified in the standards for flame-retardant performance notified by the National Fire Agency pursuant to the Enforcement Decree of the Act on Installation, Maintenance and Safety Management of Firefighting Facilities and meets the standards. In other words, the flame retardant performance test for flame retardant panels includes test items such as afterburn time (within 10 seconds), afterburn time (within 30 seconds), charred area (within 50 cm²), charred length (within 20 cm), and smoke density (maximum smoke density, 400 or less), and all of the specified standards must be passed. Here, the "afterglow time" refers to the time from when the burner flame is removed until the state of burning with a rising flame ceases. The above "residual flame time" refers to the time from when the burner flame is removed until the state of combustion without raising the flame ceases (excluding the time during which residual flames occur). The above "carbonized area" refers to the area carbonized by the flame. The above "carbonization length" refers to the length carbonized by a flame. The above "maximum smoke density" refers to the amount of smoke generated during combustion. However, in conducting flame retardant performance tests on the aforementioned flame retardant panels, the test items of residual time and maximum smoke density have an inverse relationship; consequently, there are difficulties in passing the prescribed standards, such as the problem of the maximum smoke density being unsuitable when attempting to pass the residual time test, and the problem of the residual time being unsuitable when attempting to pass the maximum smoke density test. In order to solve these conventional problems, the applicant filed an application for a flame-retardant panel manufacturing technology and obtained registrations such as KR 10-1447235 (flame-retardant panel and method of manufacturing the same) and KR 10-1706226 (method of manufacturing a flame-retard
