[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a modified graphite polyurethane insulation board, comprising...

[0025] The modified graphite polyurethane insulation board body 100 includes an insulation board connecting assembly 110 and an insulation board insulation protection assembly 120. The insulation board connecting assembly 110 is laid out in sequence and includes a board body 111. Connecting ears 114 and snap-fit ​​ears 115 are respectively provided on both sides of the board body 111. The connecting ears 114 and snap-fit ​​ears 115 are staggered. The insulation board insulation protection assembly 120 includes a polyurethane insulation layer 121. Alkali-resistant mesh cloth 124 is respectively provided on both sides of the polyurethane insulation layer 121. The alkali-resistant mesh cloth 124 is tightly attached to the polyurethane insulation layer 121. The insulation board insulation protection assembly 120 is used to improve the insulation of the insulation board and improve the protection of the insulation board insulation protection assembly 120. The insulation board connecting assembly 110 facilitates the splicing of the insulation board.

[0026] Please see Figure 2 and Figure 3 Connecting ears 114 and snap-fit ​​ears 115 are diagonally connected to both sides of the plate 111, and are staggered to prevent gaps when the two insulation boards are joined. A snap-fit ​​strip 116 is fixedly connected to the inner side of the snap-fit ​​ear 115, and a groove is provided on the inner side of the connecting ear 114 to mate with the snap-fit ​​strip 116, improving the connection's strength. The width of the connecting ears 114 and snap-fit ​​ears 115 is 0.5 times the width of the plate 111, facilitating joint installation and eliminating gaps. Limiting protrusions 112 are fixedly connected to the bottom of the plate 111, and are evenly distributed at the bottom. Matching limiting grooves 113 are evenly distributed at the top of the plate 111 to mate with the limiting protrusions 112, facilitating vertical positioning. The bottom of the limiting protrusion 112 is frustum-shaped, and the top of the limiting protrusion 112 is cylindrical. The top of the cylinder above the limiting protrusion 112 is arc-shaped. The limiting groove 113 is filled with adhesive, and the limiting protrusion 112 is bonded to the inside of the limiting groove 113.

[0027] Please see Figure 3 and Figure 4A polymer insulation mortar layer 123 is disposed between the inner side of the polyurethane insulation layer 121 and the alkali-resistant mesh 124, while the alkali-resistant mesh 124 is disposed on the outer side of the polymer insulation mortar layer 123. The polymer insulation mortar layer 123 significantly improves the adhesion and insulation effect of the insulation board, while the alkali-resistant mesh 124, as a reinforcing material, significantly improves the crack resistance and tensile strength of the insulation board. An inorganic fireproof coating 122 is disposed between the polymer insulation mortar layer 123 and the polyurethane insulation layer 121. Adding the inorganic fireproof coating 122 to the outside of the insulation board significantly improves its fire resistance. The outer side of the polyurethane insulation layer 121 is bonded to the alkali-resistant mesh 124, and a grid layer 125 is connected to the outer side of the alkali-resistant mesh 124, serving both decorative and protective functions, and also improving the durability and wind pressure resistance of the insulation board to a certain extent. A reflective heat insulation film layer 126 is attached to the outside of the barrier layer 125. The reflective heat insulation film layer 126 can effectively reflect solar radiation heat, reduce the temperature of the insulation board surface, and thus improve the heat insulation effect.

[0028] Working principle: When installing the modified graphite polyurethane insulation board body 100, a mixed adhesive is evenly adhered to the alkali-resistant mesh cloth 124 on the inner side of the polyurethane insulation layer 121. The modified graphite polyurethane insulation board body 100 is then pasted onto the wall. When multiple modified graphite polyurethane insulation board bodies 100 are pasted together in sequence, the locking strip 116 on one side of the insulation board connecting component 110 is engaged with the groove on one side of the connecting ear 114. At the same time, the limiting protrusions 112 of the upper and lower corresponding insulation board connecting components 110 are correspondingly bonded with the matching limiting grooves 113, thereby improving the firmness of the insulation board connecting component 110 installation.
