Example 1:

[0019] like Figure 1 As shown, this embodiment provides a glass fiber insulation board, which includes a glass fiber layer 1, a flame-retardant fiber layer 5 fixedly disposed on the top of the glass fiber layer 1, an anti-corrosion layer 4 disposed on the top of the flame-retardant fiber layer 5, an anti-crack layer 3 fixedly disposed on the bottom of the glass fiber layer 1, and a heat insulation layer 2 fixedly disposed on the bottom of the anti-crack layer 3.

[0020] A fiberglass insulation board includes a fiberglass layer 1, a flame-retardant fiber layer 5 fixedly disposed on top of the fiberglass layer 1, an anti-corrosion layer 4 fixedly disposed on top of the flame-retardant fiber layer, a crack-resistant layer 3 fixedly disposed on the bottom of the fiberglass layer 1, and a heat insulation layer 2 fixedly disposed on the bottom of the crack-resistant layer 3. By setting the heat insulation layer 2, heat is reflected away from the board after sunlight shines on it, improving the board's heat insulation performance. Simultaneously, the low heat reflection ensures a good heat insulation effect. Compared to existing technologies, this solves the technical problem of poor heat insulation or thermal insulation performance of existing boards, which reduces their practicality.

[0021] Further, the material of the heat insulation layer 2 is heat-reflecting material. The heat insulation layer 2 comprises a polyimide film and an aluminum foil layer, the polyimide film is fixedly connected to the upper and lower ends of the aluminum foil layer, and through the cooperation between the polyimide film and the aluminum foil layer, the heat can be reflected away after the sunlight is irradiated on the plate, thereby improving the heat insulation performance of the plate.

[0022] Further, the material of the anti-cracking layer 3 is carbon fiber material, the carbon fiber has high tensile strength, thereby further improving the overall tensile strength of the plate.

[0023] Further, the anticorrosive layer 4 is coated paint, thereby realizing the anticorrosive function of the plate.

[0024] Further, the material of the flame-retardant fiber layer 5 is polyimide fiber. The polyimide fiber is resistant to high temperature, self-extinguishing after leaving the fire, has good heat insulation property, has good flame-retardant effect, and achieves the effect of improving the flame-retardant property of the plate.
