Inventor: GONG SUK TAE
IPC: E04B1/76
Filed: 2020-08-27
Abstract: A vacuum insulator is generally formed by inserting a gap for maintaining a vacuum between boards and extracting air from the edge thereof. The type of filler that forms the gap varies depending on developers. Glass fiber mats, eco-friendly organic fibers extracted from cocoa fruits, and non-woven fabrics are used as the filler. The filler is applied in a checkerboard pattern by plasticizing to create a filling gap formed as diaphragms that are separated from each other. Inside a vacuum chamber, plastic boards are attached to both sides of the filling gap, and pressed with a hot plate protruding in a checkerboard pattern so that the plastic boards come in contact with both the sides. When the vacuum insulator is in use, if the same is cut based on the traces of the hot plate, the vacuum insulator, of which the internal vacuum formed by each diaphragm is maintained and can be cut and used, can be made. In the above description, a structure for making the diaphragm has been described as the checkerboard pattern, which is for easy explanation of the invention. The structure can be applied and used in various shapes such as circular, triangular, and hexagonal shapes and various methods. In a thermocompression bonding method, a protruding portion for forming a thermocompression mold diaphragm results in a better result. The protruding shape is similar to that of a fibrous diaphragm, and a slightly narrow width thereof is better. In addition, instead of fibrous fillers, plastics with a checkered diaphragm structure can be used. In addition, the vacuum insulator can be formed on one side of an outer skin layer to protrude in a checkerboard shape and be used.
