Problems solved by technology

The combustion performance of the core material and adhesive after flame-retardant treatment can only reach Class B. Even if the combustion performance of the lightweight core material and adhesive both reach Class B, after compounding with the color steel plate, due to the strong heat conduction of the color steel plate effect, its combustion performance will often drop to D or E level

Embodiment 1

[0028] On the color steel sandwich panel production line, the color steel plate with a thickness of 0.3mm as the upper metal panel (1) and the color steel plate with a thickness of 0.3mm as the lower metal panel (2) are placed before the steel plate is grooved or the steel plate is grooved Finally, drip the adhesive on the side of the metal panel facing the light core material (3) through the glue dispensing device, and then apply the adhesive evenly through the glue leveling device to form an adhesive layer (4). The adhesive used is polyurethane adhesive (black and white glue ), consisting of white glue composed of combined polyether and black glue composed of isocyanate, the amount of black and white glue is 0.12kg / m 2 The upper and lower metal panels (1, 2) that have been coated with glue and the molded polystyrene (EPS) foam board as the lightweight core material (3) are compounded by a composite machine. The limiting oxygen index of the EPS foam board used is 34.5, and the...

Embodiment 2

[0031] In the color steel sandwich panel production line, the galvanized color steel plate with a thickness of 0.3mm as the upper metal panel (1) and the galvanized color steel plate with a thickness of 0.3mm as the lower metal panel (2) are placed before the steel plate is grooved Or after the steel plate is grooved, use the glue dispensing device to drip the adhesive on the side of the metal panel facing the light core material (3), and then use the glue leveling device to evenly coat the adhesive to form an adhesive layer (4). The adhesive used is polyurethane Adhesive (black and white glue), composed of white glue composed of combined polyether and black glue composed of isocyanate, the amount of black and white glue is 0.11kg / m 2 The upper and lower metal panels (1, 2) that have been coated with glue and the EPS foam board as the lightweight core material (3) are compounded by a composite machine. The limiting oxygen index of the EPS foam board used is 32.5, and the thickn...

Embodiment 3

[0034] In the color steel sandwich panel production line, the galvanized color steel plate with a thickness of 0.5mm as the upper metal panel (1) and the galvanized color steel plate with a thickness of 0.5mm as the lower metal panel (2) are placed before the steel plate is grooved Or after the steel plate is grooved, use the glue dispensing device to drip the adhesive on the side of the metal panel facing the light core material (3), and then use the glue leveling device to evenly coat the adhesive to form an adhesive layer (4). The adhesive used is polyurethane Adhesive (black and white glue), composed of white glue composed of polyether and black glue composed of isocyanate, the amount of black and white glue is 0.13kg / m 2 ; The upper and lower metal panels (1, 2) coated with glue and the extruded polystyrene (XPS) foam board as the lightweight core material (3) are compounded by a composite machine. The XPS foam board used has a limiting oxygen index of 30.5, and the XPS fo...

Abstract

The invention discloses a colour steel sandwich panel with high combustibility grades, which comprises an upper metal panel (1), a lower metal panel (2) and a light core material (3); and the light core material (3) is arranged between the upper metal panel (1) and the lower metal panel (2) and is integrally connected with a cementing compound layer (4) between the upper metal panel (1) and the lower metal panel (2) through the light core material (3); the colour steel sandwich panel with high combustibility grades is characterized in that: at least one fireproof parting strip (5) is arranged in the light core material (3) vertical to the upper metal panel (1) and the lower metal panel (2); and the thickness of the fireproof parting strip (5) is equal to that of the light core material (3). The invention also discloses a preparation method of the colour steel sandwich panel. The fireproof parting strip arranged in the colour steel sandwich panel can prevent flames from spreading, delay the heat transfer speed, weaken the drop melting degree of the light core material and the cementing compound, and greatly reduce the fire risk of the colour steel sandwich panel when in use. The preparation method is simple and convenient; moreover, the preparation method is also easy for control and industrial production.

Description

technical field [0001] The invention belongs to the technical field of a color steel sandwich panel and a preparation method thereof, and in particular relates to a color steel sandwich panel with a high combustion performance grade of a fireproof partition and a preparation method thereof. Due to the existence of fire-proof partitions, this type of color steel sandwich panel blocks the path of fire propagation and slows down the heat transmission speed, thus endowing the color steel sandwich panel with a high single combustion test level. Background technique [0002] Color steel sandwich panel refers to a new type of building material composed of light core material and metal panel. It has the characteristics of light weight, heat preservation, sound insulation, and quick construction. It is widely used in temporary buildings, warehouses, special buildings, large The roof, wall and interior and exterior wall decoration of span steel structure houses. The lightweight core ...
