Application of PU-coated paper on aluminum honeycomb panels

 

As a high-performance composite material, aluminum honeycomb panels are widely used in construction, transportation, aerospace, and other fields due to their lightweight, high strength, corrosion resistance, easy processing, and other characteristics.

Finish foil paper, as an important part of the Aluminum Honeycomb Panel, plays a key role in improving the material’s performance, beautifying the appearance, and enhancing the service life.

 

In this paper, we will analyze the application of Finish Foil on aluminum honeycomb panels， including its definition and characteristics, advantages, production process, etc.

 

Introduction of the characteristics of aluminum honeycomb panel

 

Aluminum honeycomb panel is a kind of lightweight and high-strength panel，made of two or more layers of aluminum alloy panel and honeycomb aluminum core in the middle，compounded by a special process.

 

Its characteristics mainly include the following aspects:

1. Light weight and high strength

Aluminum honeycomb tekboard is mainly used for furniture making such as desk, office table etc, the honeycomb structure makes the whole furniture’s weight down but also keep the strength for daily using. Due to the metal material has better strength than the nature wood or others wood like board, so aluminum tekboard can serve you for a long time, after applying the wood grain finish foil paper on the aluminum honeycomb, this material will be an amazing wood like board compared with plywood, MDF or others.

 

2. Corrosion Resisitence

Aluminum alloy has good corrosion resistance and can resist a wide range of chemicals.  Aluminum alloy is a kind of material with good corrosion resistance and it is not a positive material different from iron grey which can be active with coffee, tea, milk etc wet liquid food, some makeup product, or kitchen additive food. The corrosion resistance is a great feature of aluminum tekboard furniture board.  ）

 

3. Sound and heat insulation

The aluminum honeycomb structure is a special design to isolate sound, the noise will be down and down during the transmission of sound after multiple layers air and aluminum. If we use this honeycomb aluminum board as a wall panel, I think it is great for a peaceful space, so do furniture, no more sound shake. Heat insulation is the special feature of aluminum, it is a famous heat insulation material in metals, so it is always used for warm machines in winter.)

 

4. Easy processing

Aluminum honeycomb panels can be made into kitchen countertops, can be easily cut to the right size, easy to install. It can also be used for bathroom partitions, waterproof and moisture-proof and easy to clean. It has highly customizability to meet the needs of different home styles, and is an ideal decoration material for life.

 

Ⅱ Definition and characteristics of Finish Foil Paper

1. Definition

Finish Foil Paper is a material used to decorate and protect the surface of aluminum honeycomb panels. It is usually made of resin, paper, and ink. This kind of paper has PU coating on the surface, do not need to paste on the wood and then paint， like board. The medium is white glue or wood glue, no harmful substances to health, or environmental protection.

 

2. Characteristics

Scratch resistance

In the process of opening and closing the cabinet door of the wooden wardrobe, the cabinet door will rub against the border of the wardrobe. At the same time, during daily cleaning and sorting of clothes, it may also accidentally touch the surface of the cabinet door. But the cabinet door decorated with PU paper can resist these frictions, will not show signs of wear and tear, and always maintains a beautiful appearance.

 

Dirty resistance

Dining room chairs are often stained with food, such as oil stains, soup, etc. PU paper does not absorb water and has a smooth surface. If the back and seat cushions of the chair are decorated with PU paper, when the soup splashes on it, the stain will not penetrate quickly, but stay on the surface. We can clean easily. And even after multiple such cleanings, the color and pattern of the PU paper will not change.

 

Sickness resistance

When students or office staff use sticky items such as glue and tape on the desk, it may stick to the table. If the desk is decorated with PU paper, it is relatively easy to deal with. Because the surface of PU paper is smoother, the glue will not stick as easily as it does on ordinary wood. For the residual glue marks of the tape, you can use alcohol to clean it up, which will not cause damage to the surface of the PU paper or leave obvious marks.

 

 

3. A wide variety of designs available for decorating foil

Wood Grain

 

Solid PU Paper

 

New trend

Classic PU Coated

 

4. Influence of Price Factors

Raw material cost: The price fluctuation of raw materials such as decorative paper, water-based resin, surface paint, etc.

 

Color types: The price of some special effects or precious wood grain colors is higher, while the price of common colors is relatively low.

 

Oil plate thickness

An increase in the thickness of the plate means that more PU coating material has to be used in the production process, which has its own cost, and an increase in the amount of PU coating material used increases the cost of purchasing the raw material accordingly.

 

Molding: If the modeling of paint-free paper is relatively simple, such as just flat texture patterns, single geometric shapes, etc., the production process is relatively simple, the cost is low, and the price will be relatively cheap. When the paint-free paper has a complex modeling design, such as three-dimensional effects, irregular curves, etc., the production process requires a higher level of technology and more complex processes, which will increase the production costs, resulting in higher prices.

.

Ink Quality: High-quality inks can render better colors. For example, when printing wood grain patterns, high-quality inks can realistically restore the natural color and texture of wood. High-quality ink has good color stability, and the colour is not easy to change after a long time of light. For furniture, this is very important, because furniture will be tested by various environmental factors in the process of use. High-quality inks cost more, so the price of paintless paper using these inks will also be relatively high.

 

Ⅲ Production process of PU-coated paper

1 Production process

• Preparing raw materials

wood pulp, titanium dioxide, talcum, kaolinite

• Preparing equipment/material

place cylinder sets aside of the production line（All of these cylinder sets need to be cleaning in the washing machine）

place based paper on the machine

• Adjusting color
• adjusting the ink color on the sample
• scratching color to matching
• adjusting based painting color
• pulling painting to the container for printing
• adjusting painting color again

 

• Printing
• Printing based color on paper
• Printing second paint color
• Printing third painting color
• Printing fourth painting color

 

1.5 Coating

• First PU coating for paint protection
• Second PU coating for paint protection

 

1.6 Cutting

• Cut the finished foil paper as required by roll
• Check the paper quality

 

1.7 Packaging

• Check the paper quality
• Packaged with oil paper(anti-water, anti-dirt)

 

1.7 Drying

For PU coating on the surface can be dried out better, we always don’t package the top finish foil at 50 degrees.

 

Ⅳ Advantages of Finish Foil’s application in aluminum honeycomb panels

1. Good bonding with aluminium honeycomb panels

Finish Foil can be tightly bonded with aluminium honeycomb panels by means of adhesives and other means, and it is not easy to be detached or delaminated, which ensures the integrity and stability of the decorative materials.

2. Easy to process and mold

Finish Foil can be bent, folded, and cut according to different design requirements, and when combined with aluminium honeycomb panels, it can meet a variety of complex shapes and structural needs.

For example, in the decoration of a desk, a curved decorative material may be required to fit the shape of the desk. Aluminium honeycomb panels affixed with Finish Foil can be made into curved panels through special processing technology

3. Good resistance to contamination

The surface of Finish Foil is not easily stained, so it is easy to clean and maintain as it is not easily adhered to dust and stains. For example, in an environment prone to oil pollution, such as the kitchen, aluminum honeycomb panels with Finish Foil are used as cabinet panels, and only need to be wiped with a damp cloth when cleaning, saving cleaning time and costs.
