Single-sided color steel inorganic silicon crystal smoke prevention and exhaust air duct plate and manufacturing method thereof

Abstract

The invention provides a single-sided color steel inorganic silicon crystal smoke prevention and exhaust air duct plate and a manufacturing method thereof. The single-sided color steel inorganic silicon crystal smoke prevention and exhaust air duct plate comprises an outer-layer color steel plate, an inner-layer inorganic silicon crystal plate and a middle-layer flame-retardant polyurethane gel, and the inner layer and the outer layer are bonded through the middle layer. The composite plate has the respective advantages of an inorganic silicon crystal plate and a color steel plate, and has the advantages of heat insulation, light weight, high strength and excellent fireproof and high-temperature-resistant performance. The color steel plate serving as the outer layer of the air duct is attractive, high in strength and resistant to impact, dust is not prone to being attached, cleaning is easy, the inorganic silicon crystal plate serving as the inner layer of the air duct is smooth in surface, small in wind resistance, resistant to corrosion, resistant to abrasion and long in service life, the inorganic silicon crystal plate is resistant to expansion and contraction, and the phenomenon of bending deformation caused by temperature changes cannot occur when the inorganic silicon crystal plate is bonded with the color steel to serve as a composite plate. Meanwhile, the manufacturing method and technological parameters are optimized, the adhesive layer is fast in curing, high in adhesion and suitable for continuous and fast production, and compared with other metal surface composite plates, the production cost is lower.

Description

technical field [0001] The invention relates to the field of smoke prevention and exhaust air ducts, in particular to a single-sided color steel inorganic silicon crystal smoke prevention air duct plate and a manufacturing method thereof. Background technique [0002] At present, the common air ducts on the market include inorganic fiberglass air ducts, galvanized steel air ducts, and color-plastic steel air ducts. Difficult, and bear heavy, make the load of building bigger. And other low-cost panels for air ducts, such as polyurethane panels and polystyrene panels, are light in weight and have certain thermal insulation properties, but their strength is poor, and their fire performance cannot meet the requirements. There are some disadvantages of brittleness and easy pulverization. [0003] The composite air duct panel is a composite panel composed of at least two materials, which can give full play to the advantages of different material panels and avoid their respective...

AI Technical Summary

Problems solved by technology

Because the core material of the composite sandwich panel is wrapped inside, and the inner surface of the single-sided composite panel is used as the inner surface of the air duct, so the requirements for the inner layer surface are higher, light heat preservation, heat insulation and fire prevention, and non-toxic. Toxic environmental protection, smooth surface are indispensable, and the composite bonding effect of the metal outer panel and inner panel also affects the final product quality, which limits the application and promotion of single-sided composite panels
