In foreign countries, there are many names of aluminum-plastic plates, including aluminum composite panels; Some are called aluminum composite materials; In many European countries, aluminum-plastic plate is called Alucobond, which comes from a trade name of aluminum-plastic plate. There are not many foreign enterprises producing aluminum-plastic plates, but the production scale is very large. Famous companies include alusuisse company headquartered in Switzerland, Reynolds metal company of the United States, Mitsubishi company of Japan, Daming of Korea, etc. Taiwan auspicious, the mainland's famous enterprises are Ningbo Aijia building materials and so on.
[aluminum plastic plate] is composed of two materials (metal and non-metal) with different properties. It not only retains the main characteristics of raw materials (metal aluminum and non-metal polyethylene plastic), but also overcomes the shortcomings of raw materials, and then obtains many excellent material properties, such as luxury, colorful decoration, weather resistance, corrosion resistance, trauma resistance, fire prevention, moisture resistance, sound insulation, heat insulation and earthquake resistance; Light weight, easy processing and molding, easy handling and installation. Therefore, it is widely used in various architectural decoration, such as ceiling, wrapped column, counter, furniture, telephone booth, elevator, storefront, billboard and plant wall materials. It has become the representative of metal curtain wall among the three curtain walls (natural stone, glass curtain wall and metal curtain wall). In developed countries, aluminum plastic plate is also used in the manufacture of buses and train cars, sound insulation materials of aircraft and ships, design of instrument boxes, etc.
There are many kinds of aluminum-plastic plate, and it is a new material. Therefore, there is no unified classification method so far. It is usually classified according to the purpose, product function and surface decoration effect.
(1) Classification by purpose
a. The minimum thickness of the upper and lower aluminum plates of the aluminum-plastic plate for building curtain wall shall not be less than 0.50mm, and the total thickness shall not be less than 4mm. The aluminum material shall meet the requirements of GB / T 3880. Generally, 3000, 5000 and other series of aluminum alloy plates shall be used, and the coating shall be fluorocarbon resin coating. b. Aluminum plastic plate for exterior wall decoration and advertising. The upper and lower aluminum plates shall be antirust aluminum with a thickness of not less than 0.20mm, and the total thickness shall not be less than 4mm. The coating is generally fluorocarbon coating or polyester coating. c. The upper and lower aluminum plates of indoor aluminum-plastic plates generally adopt aluminum plates with a thickness of 0.20mm and a minimum thickness of no less than 0.10mm, and the total thickness is generally 3mm. The coating shall be polyester coating or acrylic coating.
(2) Classification by product function
a. The fireproof board adopts flame-retardant core material, and the combustion performance of the product reaches flame retardant grade (B1 grade) or non combustible grade (a grade); At the same time, other performance indexes must also meet the technical index requirements of aluminum-plastic plate. b. Antibacterial and mildew proof aluminum plastic plate coating the coating with antibacterial and bactericidal effects on the aluminum plastic plate to control the activity and reproduction of microorganisms and finally kill bacteria. c. Antistatic aluminum-plastic plate antistatic aluminum-plastic plate is coated with antistatic coating. The surface resistivity is less than 109 Ω, which is lower than that of ordinary aluminum-plastic plate. Therefore, it is not easy to generate static electricity and dust in the air is not easy to adhere to its surface.
(3) Classified by surface decoration effect
a. Coated decorative aluminum-plastic plate various decorative coatings are coated on the surface of the aluminum plate. Fluorocarbon, polyester and acrylic coatings are widely used, mainly including metal color, plain color, pearlescent color, fluorescent color and other colors. They have decorative effect and are the most common varieties in the market. b. Anodized colored aluminum-plastic plate is treated in time by anodizing. The aluminum alloy panel has unique colors such as rose red and bronze, which plays a special decorative effect. c. Laminating decorative composite board is to make the colored film adhesive on the aluminum plate coated with primer or directly pasted on the aluminum plate after degreasing treatment according to the set process conditions and relying on the action of adhesive. The main varieties are gang grain, wood grain board, etc. d. The color printed aluminum-plastic plate prints different patterns on the transfer paper with color ink through the advanced computer Phototypesetting printing technology, and then indirectly copies various natural patterns on the aluminum-plastic plate through the thermal transfer technology. It can meet the creativity of designers and the personalized choice of owners. e. Wire drawing aluminum-plastic plate adopts aluminum alloy panel with wire drawing treatment on the surface. Gold wire drawing and silver wire drawing products are common, which bring different visual feelings to people. f. The surface of mirror aluminum plastic plate and aluminum alloy panel is polished, just like a mirror.
(1) Super peeling degree
The aluminum-plastic composite plate adopts a new process, which improves the peel strength, the most key technical index of the aluminum-plastic composite plate, to an excellent state, and improves the flatness and weather resistance of the aluminum-plastic composite plate accordingly.
(2) The material is easy to process
The weight of aluminum-plastic plate per square meter is only about 3.5-5.5kg, so it can reduce the harm caused by earthquake and is easy to handle. Its superior construction can complete various shapes of cutting, cutting, edge planing, bending into arc and right angle with simple woodworking tools. It can cooperate with designers to make various changes. The installation is simple and fast, reducing the construction cost.
(3) Excellent fire resistance
The middle of the aluminum-plastic plate is flame-retardant PE plastic core material, and the two sides are extremely difficult to burn aluminum layers. Therefore, it is a safe fireproof material, which meets the fire resistance needs of building regulations.
(4) Impact resistance
Strong impact resistance, high toughness, bending does not damage the finish paint, strong impact resistance, and there will be no damage caused by wind and sand in areas with large wind and sand.
(5) Super weather resistance
As the fluorocarbon paint of PVDF based on kynar-500 has unique advantages in weather resistance, it will not damage the beautiful appearance in hot sunshine or cold wind and snow, and will not fade for 20 years.
(6) Uniform coating and various colors
After chemical treatment and the application of Henkel film technology, the adhesion between paint and aluminum-plastic plate is uniform, and the colors are diverse, giving you more choice space and showing your personalization.
(7) Easy maintenance
Aluminum plastic plate has been significantly improved in pollution resistance. China's urban pollution is relatively serious. It needs to be maintained and cleaned after a few years of use. Due to its good self-cleaning property, it only needs neutral cleaning agent and clean water to make the plate permanent as new after cleaning.
