Natural stone has become one of the indispensable decorative materials in the market due to its rich texture and high hardness. However, stone as a non-renewable resource, in order to reduce the excessive consumption of the earth’s resources, people pay more and more attention to the rational use of stone. The appearance of the imitation stone aluminum veneer makes up for the defects of the traditional stone itself, and can achieve the decorative effect of imitation stone without consuming resources, and is more and more favored by the majority of owners. So, what is imitation stone aluminum veneer? Today we will talk about this knowledge, hoping to help everyone.

1. What is stone grain aluminum veneer?
- The appearance and texture of imitation stone aluminum veneer are very similar to natural stone, and it can be said that the decorative effect is the same as that of stone. In terms of performance, the physical properties of the imitation stone aluminum veneer are better than those of natural stone, and the recyclability of the imitation stone aluminum veneer is more worthy of promotion
- The imitation stone aluminum veneer is processed and produced by the aluminum veneer manufacturer using high-grade aluminum alloy plates, and its thickness is: 1.5mm, 2.0mm, 2.5mm, 3.0mm, and other thicknesses can be customized. The stone pattern on the surface of the imitation stone pattern aluminum veneer is sampled from the real material, which is rich in stone texture and more realistic. And there are many surface stone patterns, which can innovate more beautiful patterns on the existing stone patterns and colors.
2. The advantages of stone grain aluminum veneer:
- Simulation effect: In addition to the simulation effect of natural slate, it also realizes the designer’s unique creativity with luxurious atmosphere and creative shape and color, giving the building a unique personality.
- Environmental protection and energy saving: It is an efficient and environmentally friendly exterior wall coating refined from chemically synthesized high molecular polymers with excellent performance.
- Waterproof and stain resistance: Effectively prevent cracks in the base layer, the coating is dense, soft, waterproof and error resistance is far superior to other curtain wall building materials, with excellent self-determination ability and error resistance.
- Lightweight and safe: high safety performance, only 1/6 of the weight of building materials, preventing potential safety hazards.
- Fast construction: It has excellent operability and greatly shortens construction time.
- Cost-effective: Compared with the basic price of traditional natural stone per square meter, the price of imitation stone is about 1/5 of that of natural stone.
- Strong plasticity: Aluminum veneer has strong plasticity and can be processed into complex structural styles such as flat plates, curved plates, and concave-convex textures.
3. Stone pattern aluminum veneer process:
There are two main surface treatment processes for imitation stone aluminum veneer: one is stone thermal transfer process, the other is imitation stone paint
3.1 Stone thermal transfer process
The first part of the processing of stone-grained aluminum veneer is to carry out sheet metal forming first, and then process it into a preset shape according to the drawing design. It is necessary to add reinforcing ribs and add corner codes. Then, it is treated before spraying to remove impurities on the surface of the aluminum veneer. Make the paint film better adhere to the surface of the aluminum veneer.
The second major part is powder coating and transfer printing. Powder spraying is to use the principle of electrostatic spraying to make the dry powder coating adsorb on the aluminum alloy sheet. After high temperature baking, the surface powder solidifies into a solid and bright coating. Wrap the sprayed aluminum veneer with the selected stone pattern transfer paper, and fix it with high temperature resistant adhesive tape to prevent the stone pattern transfer paper from loosening and affecting the texture effect.
In addition, the transfer surface of the stone pattern aluminum veneer should be directly attached to the front side of the stone pattern heat transfer paper. Bake the wrapped stone-grain aluminum veneer. The baking time and temperature need to be comprehensively determined according to the selected materials and the depth of the transfer texture. After baking, take out the baked stone-grain aluminum veneer. , tear off the thermal transfer paper, and finally clean the surface.
3.2 Imitation stone paint process
After five coats and five bakes, the paint is subjected to a high temperature of 224°C to 255°C, and the dry film thickness of the formed baking paint is: polyester 20μm～25μm, fluorocarbon 25μm～30μm. In addition, the surface is covered with 10μm thick varnish. Relying on high quality to ensure weather resistance. The warranty period of PVDF board is 20 tau. It can be used as exterior wall and curtain wall board.
Imitation stone paint surface gloss is high. The high-gloss board can reach 100°～110°, the board surface is smooth and not stained with oil, and the oil pen painting can also be wiped clean. Among them, clean board varieties, with special materials added to paint, anti-static, anti-dust, suitable for use in kitchens, disinfection rooms, operating rooms and other places, is an ideal anti-fouling cleaning board.
The imitation stone paint aluminum veneer is handled with a hand-held spray gun, and the imitation stone paint aluminum veneer needs to be placed in a cool place to dry naturally. In addition, the imitation stone paint can also use imitation stone lines on the surface of the aluminum veneer to achieve the effect of imitating stone.
