[0002] Graphite extruded board is a high-performance thermal insulation material made of polystyrene resin and special graphite material. This material is heated and extruded through a special process and has a honeycomb closed-cell structure. Its closed-cell structure is filled with C02 gas, which does not damage the ozone layer. Therefore, it is more environmentally friendly than traditional materials using CFC or HCFC gas. Graphite extruded board is widely used in the field of building insulation and has become one of the first choices for future building insulation materials due to its excellent performance.

[0003] However, the existing conventional graphite extruded board has poor thermal insulation, which makes the internal and external environments of the graphite extruded board very different, and the quality and performance are greatly affected by the humidity of the environment. Excessive humidity will affect its thermal insulation and heat preservation performance, and even cause volume expansion and deformation. It is also easily affected by the environment and accelerates aging, which leads to the problem of poor use effect of the graphite extruded board, greatly reducing the practicality of the graphite extruded board.
