Referring to fig. 1 and 2, in the present embodiment, the composite board is mainly used to enclose a relatively isolated space to perform the functions of thermal insulation, heat insulation and fire prevention, and is often used for isolating plant workshops or equipment. The composite panel includes outer plates 100, an insulating layer 200 sandwiched between the outer plates 100, and a foamed layer 300 surrounding the insulating layer 200. The foaming layer 300 has a ring structure, and the foaming layer 300 is sandwiched between the two outer plates 100 to seal the periphery of the heat insulating layer 200.

The insulation layer 200 is sealed by the foaming layer 300 and the two outer plates 100, so that rainwater or other substances can be effectively prevented from entering the insulation layer 200, and the heat insulation performance of the insulation layer 200 can be effectively guaranteed.

In this embodiment, the heat insulation layer 200 is a rock wool layer made of rock wool boards. The rock wool is an inorganic substance, is an A-grade fireproof material, has the functions of sound absorption, heat preservation, water prevention, fire prevention and flame retardance, and enables the composite board to have the capabilities of sound absorption, heat preservation, water prevention, fire prevention and flame retardance.

In this embodiment, the two outer plates 100 are metal plates, and the metal plates enhance the mechanical properties of the composite plate and effectively maintain the shape of the composite plate. The metal plate may be made of metal material such as aluminum, steel, etc. The plate shape of the outer plate 100 may be a flat plate, a corrugated plate, a trapezoidal plate, or the like, as required.

The outer panel 100 serves as a shaping function to maintain the shape of the composite panel when the composite panel is in use. The outer panel 100 covers the heat insulating layer 200 to prevent rainwater or other substances from entering the heat insulating layer 200 from both the upper and lower surfaces of the heat insulating layer 200, thereby performing waterproof, fireproof and dust-proof functions.

The foam layer 300 is formed by foaming polyurethane to seal the periphery of the insulation layer 200, and the outer panel 100 seals the upper and lower surfaces of the insulation layer 200, thereby sealing the insulation layer 200 between the outer panel 100 and the foam layer 300 to seal the rock wool panel.

In practical application, the heat conductivity coefficient of the rock wool is 0.035W/m x DEG C, the national standard requirement of mass water absorption of the rock wool is less than 10 percent, and the national standard requirement of volume water absorption is less than 10 percent. The heat transfer coefficient of rock wool materials is influenced by the water absorption rate of the rock wool, the higher the heat conductivity coefficient is, the poorer the heat insulation performance of the rock wool board is, and meanwhile, the higher the water absorption rate is, the weight of the rock wool board is increased, so that the pressure bearing capacity of the box body is reduced, and the risk of deformation and damage of the box body is increased; polyurethane is used for sealing the periphery of the rock wool board, the polyurethane is used for sealing the peripheral gaps of the rock wool board, the water absorption path of the rock wool board is blocked, the heat insulation performance of the box board is improved, and the structural strength of the composite board is ensured.

Meanwhile, the polyurethane is a low-thermal-conductivity material, the thermal conductivity coefficient is 0.022W/mXDEG C, and the composite board can achieve better heat insulation performance at the foaming layer 300.

The frame 400 closes and covers the outer circumference of the foam layer 300 to protect the foam layer 300. During transportation or installation, the polyurethane material of the foam layer 300 is prevented from being impacted or scratched, and the foam layer 300 is prevented from being damaged.

In this embodiment, the frame 400 is formed of four separate strip-shaped structures, and corresponds to four outer side surfaces of the foaming layer 300. In some embodiments, the frame 400 is an integrally formed ring structure.

In this embodiment, the frame 400 is made of plastic, and the material of the frame 400 is Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), Polystyrene (PS), or acrylonitrile-butadiene-styrene copolymer (ABS).

In this embodiment, the outer plate 100, the thermal insulation layer 200, and the frame 400 are integrally foamed with the foaming layer 300, so that the foaming layer 300 is adhered to the outer plate 100, the thermal insulation layer 200, and the frame 400, so that the composite plate is an integral body. The rock wool of insulating layer 200 is the loose structure of rock wool silk pressfitting, and the bending resistance bearing capacity is less strong, adopts polyurethane foaming banding processing all around, and each spare part adhesion becomes a whole, and rock wool board self intensity improves, improves the structural strength of whole composite sheet for the structure of composite sheet is more stable. The foaming layer 300 adheres to the periphery of the rock wool board to maintain the rock wool board in a flat laid state.
