The nylon material is firmly bonded to the inner and outer panels with 3M structural adhesive, environmentally friendly all-purpose adhesive (SBS adhesive) or instant adhesive.
[0033] Furthermore, the thermally broken aluminum includes a first thermally broken aluminum 101, a second thermally broken aluminum 102, and a third thermally broken aluminum 103. The first thermally broken aluminum 101 is disposed within the rock wool insulation layer 200, and the second thermally broken aluminum 102 and the third thermally broken aluminum 103 are respectively disposed at both ends of the rock wool insulation layer 200.

The nylon is 25% glass fiber reinforced, with a thermal conductivity ≤0.3W / m·k, ensuring extremely high strength and excellent insulation. The frame is assembled into a single unit using nylon tees and nylon two-way connectors.
[0035] The rock wool insulation layer 200 uses basalt and other natural minerals as its main raw materials.

A certain amount of binder, dust-proofing oil, and water-repellent agent are then added to the rock wool fibers. After settling, curing, and cutting, it is formed with a density ≥70kg / m3 and a thermal conductivity ≤0.035W / m·k. The rock wool insulation layer 200 is firmly bonded to the color steel plate 300 and galvanized plate 400 using a two-component polyurethane adhesive or environmentally friendly all-purpose adhesive (SBS adhesive).
