Definitions
- the present invention relates to a non-combustible heat insulating sheet, a manufacturing apparatus thereof, and a manufacturing method thereof, and more particularly, to maintain stiffness by bonding an aluminum foil with a flame-retardant adhesive layer between glass fiber fabrics in which a non-flammable coating layer is evenly laminated on both sides. It is easy to cut, and has insulation and flame retardancy, it prevents fire as well as fire due to other causes, it has a considerable delay effect to prevent the fire from getting on the back of the product.
- the present invention relates to a non-combustible heat insulating sheet, a manufacturing apparatus thereof, and a method of manufacturing the same, which can reduce human injury, and can simultaneously provide a light shielding, heat shielding, and cooling effect.
- Non-flammable or flame retardant fabrics are made of non-combustible resins on general textile fabrics as well as special textile fabrics to make them less burned. It is mainly composed of fiberglass fabrics, non-woven fabrics, and other fabrics that require flame retardancy. Adopt.
- fiber yarns are made of synthetic resin or glass fibers such as polyester, acrylic, polypropylene, and the like.
- the fabric is primarily finished through a weaving process to form a woven fabric by weaving the fabric yarn by weaving the warp yarn and the warp yarn through a separate weaving machine.
- the textile fabric firstly finished through this weaving process is a post-processing method, which allows the weft yarns and the warp yarns to be fixed to each other in a cohesive state in a separate coating machine to prevent loosening of each fiber yarn and impart proper stiffness to the back side of the fabric.
- the coating liquid coating step of applying a coating liquid having a nonflammable to be carried out and the coating liquid drying process for drying and fixing the coated coating liquid is finally completed.
- non-combustible fabrics refer to fabrics having a property that is almost incombustible
- flame-retardant fabrics refer to fabrics having a property of being hard to burn, that is, capable of being burned over time. Therefore, nonflammable fabrics have better flame resistance characteristics than flame retardant fabrics, and it is better to use glass fiber fabrics to further increase nonflammability.
- Korean Patent Publication No. 10-2009-0095822 has been proposed as an invention for a conventional non-combustible glass fabric.
- Non-combustible fabric provides a non-combustible by laminating a non-combustible coating layer on the glass fiber fabric, but in reality there is only a non-combustible non-flammable and there is a problem that does not provide sufficient incombustibility in fire.
- the existing flame retardant fabric has a problem that the flame retardant coating liquid does not evenly penetrate the fiber fabric, the fire retardant performance is significantly lowered in the event of a fire, the fabric is not smooth because the components of the coating liquid is not smooth.
- the present invention has been created by the necessity as described above, by providing a non-flammable coating layer of aluminum foil between the glass fiber fabric laminated evenly on both sides to have insulation and flame retardancy to prevent fire as well as fire due to other causes In addition, there is a significant delay effect in preventing fire from being transferred to the back of the product, and since there is almost no toxic gas, the human can be evacuated, so it can reduce the casualties and at the same time obtain the shading, shading, and cooling effect.
- An object of the present invention is to provide a non-combustible insulating sheet, a manufacturing apparatus thereof, and a manufacturing method thereof.
- the present invention is provided with a flame-retardant adhesive layer between the plurality of flame-retardant glass fiber fabric and aluminum foil to maintain the stiffness of the glass fiber fabric, so that it is attached to the wall with a stapler, nails, pieces, etc. like plywood to the insulation construction of the building
- a non-combustible heat insulating sheet an apparatus for manufacturing the same, and a method of manufacturing the same, which can be applied to, can be attached with wallpaper paste or adhesive, and are easily cut with a knife or scissors.
- an object of the present invention is to provide a non-combustible heat insulating sheet, a manufacturing apparatus, and a manufacturing method thereof, which makes the glass fiber fabric soft and smooth.
