Foam concrete sandwich color wall steel plate and production technique thereof

Abstract

The invention provides a foam concrete sandwich color wall steel plate and a production technique thereof. The foam concrete sandwich color wall steel plate comprises a first steel plate layer, a second steel plate layer, a cement paste layer, a first foam concrete layer and a second foam concrete layer, wherein the first steel plate layer and the second steel plate layer are parallel; the cement paste layer is located between the first steel plate layer and the second steel plate layer; the space between the first steel plate layer and the cement paste layer is filled with the first foam concrete layer; and the space between the second steel plate layer and the cement paste layer is filled with the second foam concrete layer. The production technique comprises the steps of die-filling, pouring, die disassembling, combining, forming and the like. The foam concrete layers are adopted as a sandwich material and are not prone to combustion, and compared with traditional sandwich materials, the foam concrete layers are relatively hard and not prone to aging, the fracture resistance is relatively good, and the service life is relatively long. In addition, the foam concrete layers and the cement paste layer are used as the sandwich material, the effect that the sandwich color wall steel plate has the strength as traditional EPS composite wallboards is ensured, and no toxic gas is emitted at high temperatures.

Description

technical field [0001] The invention relates to a prefabricated board for building and its production process, in particular to a foam concrete sandwich color wall steel plate and its production process. Background technique [0002] Sandwich color wall steel plate is a new type of enclosure structure plate integrating load-bearing, heat preservation, waterproof and decoration. It is widely used in various buildings such as industrial plants, public buildings, composite houses, and purification projects. [0003] The traditional sandwich color wall steel plate usually uses color-coated steel plate as the surface material, self-extinguishing polystyrene, polyurethane, glass wool or rock wool as the core material, and is pressurized and heat-cured in a continuous molding machine with thermosetting adhesive. , Trimming, grooving, blanking and other processes are composited ultra-light building panels. Among these core materials, only rock wool and glass wool are non-combustible...

AI Technical Summary

Problems solved by technology

[0003] The traditional sandwich color wall steel plate usually uses color-coated steel plate as the surface material, self-extinguishing polystyrene, polyurethane, glass wool or rock wool as the core material, and is pressurized and heat-cured in a continuous molding machine with thermosetting adhesive. , Trimming, grooving, blanking and other processes are composited ultra-light building panels. Among these core materials, only rock wool and glass wool are non-combustible materials. The use of other sandwich materials in color steel sandwich panels It is very easy to cause fire. At the same time, because the steel plate of the traditional sandwich color wall steel plate is usually a flat structure, the sandwich material is usually soft material, and the flexural performance is relatively poor.

[0004] In addition, the inner and outer layers of the transmission sandwich color wall steel plate are produced separately and then combined into a sandwich color wall steel plate. Many sandwich materials are often produced for a long time before being applied to the sandwich color wall steel plate. Special treatment is required to ensure the tightness of the combination, and if the sandwich material is produced for too long, it is easy to age, which will affect the service life of the entire sandwich color wall steel plate
