Description of the invention (5) Flame 3 1, contact with the bottom surface of the fireproof paper 2 4, at this time, due to the internal expansion of the graphite, the graphite is gradually expanded by heat, forming an expansion zone 241 and contacting the flame 31. Black, but does not spread to the side, that is, the expansion zone 241 does not expand. Referring to the third C and FIG. 4C, the flame generator 30 is adjusted to produce a larger flame 31, and still contacts the bottom surface of the fireproof paper 24. At this time, since the area of the contact flame 31 becomes larger, a larger one is formed. The expansion zone 241 has an expanded thickness d2. Although the portion contacting the flame 31 is black, it does not spread to the side, that is, the expansion zone 241 does not expand. Finally, please refer to the third D and D diagrams to close the flame generator 30. Since the bottom surface of the fireproof paper 24 has no fire, 31, the larger expansion zone 241 is immediately burned, and the remaining flame time and ember time are Extremely short, in line with the safety regulations of most fireproof building materials. Therefore, please refer to the fifth picture. 'If the invention is made into a wallpaper for house interiors, in the event of a fire, the part burned by the flame will become black and swell, but will not expand and spread, and will block the flame. Passed to the other side of the wallpaper, so it can effectively prevent fire and avoid burning. In summary, the advantages and effects of the present invention can be summarized as follows: [1] The fire function is excellent. Since the product of the present invention is burned by the flame, the internal expandable graphite expands, but it has the characteristics of blocking flame transmission and not burning to the garden, and therefore has an excellent fireproof function. [2] The range of applications is extremely wide. Since the present invention is a type of paper product, it can be rolled up, made into a sheet-like shape, easy to be cut, and goodly constructed, and can be made into a fireproof wallpaper, a fireproof wrapping paper sleeve (protecting important items such as magnetic sheets, optical discs). Film, etc.)
