Energy-saving environment-friendly composite color steel plate and production method thereof

Abstract

The invention discloses an energy-saving environment-friendly composite color steel plate. The energy-saving environment-friendly composite color steel plate comprises a color steel plate, a super-flame retardant crosslinked polyethylene foaming material plate, an iron red phenolic aldehyde anti-rust paint layer and a molybdenum disulfide coating. During production, the super-flame retardant crosslinked polyethylene foaming material plate, the iron red phenolic aldehyde anti-rust paint layer and the molybdenum disulfide coating are sequentially coated on the color steel plate. The energy-saving environment-friendly composite color steel plate disclosed by the invention has the advantages that the energy-saving environment-friendly composite color steel plate utilizes an adhesive-free laminating heat treatment technology and can be tightly adhered with a super-flame retardant crosslinked polyethylene foaming material plate, then the plate is protected by virtue of the iron red phenolicaldehyde anti-rust paint layer and the molybdenum disulfide coating, and the characteristics of thermal insulation, sound insulation, watertightness, prevention of moisture condensation and weather resistance of a building can be achieved only by virtue of a single-layer super-flame retardant crosslinked polyethylene foaming material plate and a single-layer color steel plate.

Description

technical field [0001] The invention relates to a plate and a manufacturing method thereof, more specifically, an energy-saving and environment-friendly composite color steel plate and a manufacturing method thereof. Background technique [0002] At home and abroad, more and more factory buildings are constructed with steel frames and color steel plates. The advantages lie in firm structure, fast construction time and low cost. However, color steel plates themselves only have the function of sheltering from wind and rain. , sound insulation, flame retardant and other functions, almost three types of thermal insulation materials and color steel plates are used in the market, and the advantages and disadvantages of each of these three types of materials are explained: [0003] 1. EPS (polystyrene) foam board is low in cost. Due to the characteristics of the foam material, it has basic properties such as heat preservation and sound insulation. However, due to the relationship b...

Problems solved by technology

[0003] 1. EPS (polystyrene) foam board is low in cost. Due to the characteristics of the foam material, it has basic properties such as heat preservation and sound insulation. However, due to the relationship between the molecular structure of the foam material, the effect on the basic performance is low. In terms of construction, it is necessary to use thicker foam boards and use glue to compound double-sided color steel plates. This process not only reflects the problem that the glue is not environmentally friendly, but also means that due to the use of double-layer color steel plates and thicker materials, it cannot Effectively reduce costs. In addition, this foam board can be used to make non-flame retardant and flame retardant products. Although it can have self-extinguishing flame retardant characteristics, the burning rate is very fast. Once the fire source fails to leave in time, a large area will be produced. Melting, can not really show the effect of blocking combustion, and this foam board will produce a lot of black smoke and dioxin after burning, which will directly affect personal safety and environmental pollution

[0004] 2. PU (polyurethane) perfusion foam board has basic properties such as heat preservation and sound insulation due to the characteristics of the foam material, but due to the relationship between the molecular structure of the foam material, the effect on the basic performance is low. If it is used in construction, It needs to use double-layer color steel plate, and the core is perfused with PU (polyurethane) rigid foaming process. It can produce non-flame retardant and flame retardant products. The advantage is that it is light in weight and can be foamed on site. In the early stage of synthesis, the material has good performance in sound insulation, heat insulation, and waterproof, but after the time of material synthesis, it begins to deteriorate, and in a high-humidity environment, the deterioration will accelerate, so it is not conducive to outdoor environments. In addition, the foaming material burns at a high speed and produces hydrogen cyanide gas, which will directly affect personal safety and environmental pollution.

[0005] 3. Rock wool and glass fiber cotton: This material has the characteristics of non-spontaneous combustion and non-combustibility, but due to the relationship between the raw material and the manufacturing process, it is prone to the problem of chipping. After human contact, skin and eye irritation problems are common, and severe cases affect the respiratory tract. Health, coupled with the poor waterproof performance of this type of product, the outer layer is usually covered with a film during production, but with the damage of the service life, it is still impossible to completely avoid the occurrence of chipping.
