Aluminum -plastic composite plate referred to as aluminum -plastic plates. It is a new material made of aluminum plates that have been treated and painted with paint, and polyethylene plastic plate as the core layer. The aluminum plastic board was first developed and produced by AIUSINGEN in Germany, and was improved by the Dutch FORKEN and ALOCA. After the 1990s, the quality of the product gradually stabilized to reach a higher level.
Because aluminum -plastic boards are composed of two materials (metal and non -metal) that are completely different in nature, it not only retains the main characteristics of the original composition material (metal aluminum, non -metallic polyethylene plastic), but also overcomes the shortcomings of the original composition materials , And also obtained many excellent material performance. Such as luxurious and beautiful, gorgeous and colorful decoration; weather resistance, corrosion resistance, impact resistance, fire prevention, moisture -proof, insulation, sound insulation, seismic resistance; light quality, easy processing molding, easy to carry and install, can be quickly constructed. These properties open up a broad prospect for aluminum -plastic panels.
Due to the many advantages of material performance, aluminum -plastic boards are widely used in various architectural decorations, such as ceiling, bag pillars, counters, furniture, telephone booths, elevators, storefalls, dustproof room wall materials, factory wall materials, factory wall materials Wait, the representative of the metal curtain wall of the three major curtain walls (natural stone, glass curtain wall, metal curtain wall). In developed countries, aluminum -plastic boards are also used in the manufacturing of buses and train boxes. Equipment, outer boxes, etc. The development of aluminum -plastic composite board in my country has only been in just ten years, and has achieved significant results. In the future, it will achieve greater development. The prospects are very broad, and the main reasons are as follows. First, aluminum -plastic board is a new type of decorative material. It has the unparalleled advantages of many other traditional decorative materials and has strong competitiveness in decorative materials.
2. my country's urban construction and real estate and decoration industries have developed rapidly, and the demand for decorative materials is very large. After the national economy has developed to a certain level, the decoration grade of the construction industry has begun to rise. This provides favorable objective conditions for the development of aluminum -plastic boards. Third, after more than ten years of efforts, the performance and application technology of aluminum -plastic composite board products have gradually been accepted by my country's architectural community. In the future, with the improvement of construction specifications, the application in the curtain wall will be further expanded. The mainstream glass curtain wall of the curtain wall has the defects of light pollution, and future development will inevitably be limited. 4. At present, the export situation of aluminum -plastic composite boards in my country is very good. This is because Chinese products are strong in terms of quality and price. As long as the quality of quality is grasped, the next stage will be obtained on this basis. More progress.
V. Aluminum -plastic composite board, as a new type of composite material, has a wide range of uses. It can not only be used in curtain walls, indoor and outdoor decorations, but also further expand to other fields. For example, civil engineering and cars such as tunnels and other vehicles. Although my country's aluminum -plastic composite board has achieved rapid development, it should still be seen that there are still many challenges in the future, and there are still a lot of work to do in terms of production technology and application technology. For example, aspects.
First, aluminum -plastic board raw material problems. Raw materials are the basis for producing qualified products. We must continue to carry out research and development of supplementary raw material technology that helps improve product quality or reduce costs on the basis of meeting the performance requirements of aluminum plastic boards.
For example, research on low -molten high -molecular membranes. This can not only avoid the burns of fluorocarbon coating, but also reduce the energy consumption in the composite process. For another example, carry out research on PE recycling materials to ensure the quality of aluminum -plastic composite board products.
Second, further development of aluminum -plastic board functions. The current development trend of decorative materials is to develop in the direction of the integration of decorative materials and functional materials, that is, the decoration and functionality of the material should be considered as possible during the design of the material. As a new type of decorative material, aluminum plastic boards must work hard on product functional development.
For example, research on electromagnetic shielding functions and thermal insulation functions. On the coating material, some development and research on functions such as antibacterial and fire prevention are performed. Third, in -depth research on the durability of aluminum plastic boards.
A large part of the aluminum -plastic board is used for outdoor, used as curtain wall or outdoor decoration. The outdoor environment is quite bad. Although since its birth in Europe in 1969, aluminum -plastic boards have been tested for more than 30 years, the problem of durability (service life) is still the focus of people's attention.
At present, the life of aluminum -plastic board manufacturers is generally dependent on the information provided by the paint. But this is still incomplete, because the performance of the coating depends not only on the coating variety used, but also related to the coating process. In addition, as the durability of aluminum -plastic plates, the environmental corrosion behavior of polymer membranes and core materials and its composite needs to be considered.
In addition, the exterior wall aluminum plastic plate also has high peeling strength during testing, but it will produce aluminum -plastic layered phenomena in engineering. Fourth, in -depth research on production technology. Composite is the key process of the production of aluminum -plastic composite boards. The determination of technical parameters such as composite temperature, time, pressure and other technical parameters is mainly based on experience. There are certain limitations. It is very important to guide the actual production reality.
