[0024] Example 1

[0025] like Figs. 1-2 As shown, this embodiment provides a heat-insulating and waterproof roll material, including a roll material body 1. The roll material body 1 includes a reflective layer 2, a heat-insulating layer 3, a waterproof layer 4, an asphalt layer 5, and a self-adhesive layer 6 stacked together. The heat-insulating layer 3 includes a glass wool surface layer 31 and a mineral wool bottom layer 32. Polystyrene foam strips 33 are arranged in an array between the glass wool surface layer 31 and the mineral wool bottom layer 32. The cross-section of each polystyrene foam strip 33 is triangular. Aluminum silicate fiber felt 34 is filled between adjacent polystyrene foam strips 33.

[0026] The insulation layer 3 is a multi-layered insulation structure composed of a glass wool surface layer 31, a mineral wool bottom layer 32, polystyrene foam strips 33, and aluminum silicate fiber felt 34. This structure reduces heat absorption and conduction, effectively preventing heat transfer to the roofing membrane and the building interior. Both the glass wool surface layer 31 and the mineral wool bottom layer 32 are fibrous insulation materials. These materials have a fibrous structure with numerous tiny gaps between the fibers, effectively preventing heat conduction. The polystyrene foam strips 33 have a closed honeycomb structure containing air bubbles, which creates sealed pores or spaces, further reducing heat transfer. The combination of these three materials significantly slows down heat conduction, convection, and radiation, improving the insulation performance of the roofing membrane. The aluminum silicate fiber felt 34 further enhances the insulation effect. Combined with the polystyrene foam strips 33, it also improves the tear resistance and toughness of the roofing membrane, enabling it to withstand greater forces and facilitating use. Reflective layer 2 highly reflects solar infrared and ultraviolet rays, effectively preventing solar heat from accumulating and causing overheating on the surface of the membrane. Simultaneously, it automatically radiates heat to cool the membrane, reducing its surface temperature. The combination of reflective layer 2 and insulation layer 3 achieves multiple insulation effects, enhancing the membrane's overall insulation performance. Waterproof layer 4 strengthens the membrane's waterproofness, preventing water penetration. Asphalt layer 5, used in conjunction with self-adhesive layer 6, improves the bond between the membrane and the building structure.

[0027] In this embodiment, the reflective layer 2 has several reflective grooves 21, each groove 21 is coated with a reflective coating, and the outside of the reflective layer is coated with a waterproof adhesive. The reflective coating includes a base material, functional fillers, and additives. The reflective grooves 21 provide high reflectivity for solar infrared and ultraviolet rays, effectively preventing solar heat from accumulating and causing temperature rise on the object's surface. Simultaneously, it automatically dissipates heat through radiation, lowering the object's surface temperature and resulting in a significant reflective heat insulation effect. The waterproof adhesive protects the reflective coating from rainwater erosion, preventing it from affecting the reflective heat insulation effect.

[0028] In the embodiment, the reflecting groove 21 is a square reflecting groove 21. The square reflecting groove 21 can efficiently capture and concentrate sunlight, improving the reflection effect of sunlight.

[0029] In the embodiment, one side of the waterproof layer 4 is a wave-shaped structure 41, and the inner recesses of the wave-shaped structure 41 are each provided with a water-swelling sealing strip 42. The wave-shaped structure 41 can collect water infiltrating into the inside of the coiled material body 1 in the inner recesses, and the water-swelling sealing strip 42 in the inner recesses can absorb water, preventing water from continuing to infiltrate, and achieving good waterproof effect.

[0030] In the embodiment, the shape of the water-swelling sealing strip 42 is matched with the inner recesses of the wave-shaped structure 41. In this way, the water-swelling sealing strip 42 can be closely attached to the inner recesses, and is more conducive to absorbing water.

[0031] In the embodiment, the waterproof layer 4 is further filled with vulcanized rubber 43, and the vulcanized rubber 43 is located below the wave-shaped structure 41. The vulcanized rubber 43 can play an anti-corrosion role, prevent water from corroding the inside of the coiled material body 1, and also improve the strength, hardness and elasticity of the coiled material body 1, and optimize the mechanical properties.

[0032] In the embodiment, one end of the coiled material body 1 is provided with a lap joint surface 11, the other end of the coiled material body 1 is provided with a lap joint portion 12 lapped with the lap joint surface 11, and the contact surfaces of the lap joint surface 11 and the lap joint portion 12 are each coated with adhesive. The lap joint surface 11 and the lap joint portion 12 are arranged to facilitate quick connection of two coiled materials, and the adhesive can prevent displacement of the two coiled materials and improve the stability and sealing performance of the two coiled materials after connection.

[0033] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
