Thermal-insulation sound-insulation fireproof colored steel sandwich plate and manufacturing process thereof

Abstract

The invention relates to the field of colored steel plates, in particular to a thermal-insulation sound-insulation fireproof colored steel sandwich plate and a manufacturing process thereof. The colored steel sandwich plate comprises two layers of colored steel plates, two side plates, two seal plates and a core material. A plurality of keels are arranged in gaps in the core material. The keels and the two colored steel plates jointly form a first cavity, a second cavity and a third cavity. A fourth cavity is formed between two corresponding keels. The first cavity, the third cavity and the fourth cavity are filled with polyurethane foam materials. The manufacturing process comprises the steps of laying of a bottom plate, laying of the keels, laying of a top plate, erecting of the side plates, sealing, pouring of foam raw materials, closing and natural foaming. According to the thermal-insulation sound-insulation fireproof colored steel sandwich plate and the manufacturing process thereof, the sound insulation effect and the thermal insulation effect are good, the flame-retardant level is high, automatic processing is convenient, and good industrial application prospects are achieved.

Description

technical field [0001] The invention relates to the field of color steel plates, more specifically, it relates to a heat-preserving, fire-proof and sound-insulating color steel sandwich panel and its manufacturing process. Background technique [0002] The color steel sandwich panel is an ultra-light building panel with a sandwich panel in the middle of two steel plates. The steel plate on the surface layer is coated with a color coating. 20~1 / 30), thermal insulation (the thermal conductivity value of the core material is ≤0.041W / m·k), high strength, bending and compression resistance, fast construction speed, bright color, etc., is a load-bearing, thermal insulation It is a new type of enclosure structure material that integrates waterproof, fireproof and decoration. It has been widely used in large industrial plants, warehouses, gymnasiums, supermarkets, activity rooms, clean workshops and other places that require thermal insulation and fire prevention.

Problems solved by technology

[0013] However, in the above technical solutions, the sound insulation performance of the color steel plate is not considered enough, because the sound can quickly propagate in the dense polystyrene core material, so the sound easily penetrates this kind of polystyrene color steel sandwich panel

However, if foamed polyurethane with good sound insulation effect is used as the core material, the bearing capacity of the produced color steel plate can only reach about 80% of that of the color steel sandwich panel made of polystyrene core material. If rock wool is used as the core material , although rock wool has good sound insulation performance, and the color steel sandwich panel made of rock wool core material has a strong bearing capacity, but rock wool generally has insufficient adhesion between the core material and the steel plate, and the rock wool core material and the steel plate The bonding force is only one-third to one-half of the bonding force between polystyrene core material and foamed polyurethane core material and steel plate.
