Wood plastic wall panels was born in the 1960s and was hailed as one of the world's top ten scientific achievements in the early days. In the early 1990s, Terex began to produce composite materials consisting of polyvinyl chloride and 50% wood fiber and began to apply them to the building door and window industry.
As a new type of composite material, wood plastic wallboard is made of wood fiber and high-density polyethylene plastic. During the production process, wood fiber, polyethylene, and other auxiliary materials are mixed, extruded, and molded to form a strong and durable wood plastic board.
As a new type of environmentally friendly material, it gradually replaces traditional materials such as wood, stone, tile, wallpaper, etc., and becomes one of the most popular indoor wall decoration materials.
To fully understand the environmental protection and physical and chemical properties of wood plastic wall panels, it is very important to understand their material composition.
| Element | Element Type | Function |
Plastic | The commonly used PVC resin model is SG7 | Used to enhance the weather resistance, waterproofness, durability, and plasticity of materials. |
Wood fiber or plant Cellulose | The ratio is 30%~70%. Generally, 150~180 μm (80~100 mesh) wood powder is used, and poplar wood powder is more commonly used. | Improve the structural strength of materials |
Calcium carbonate | Light calcium carbonate or heavy calcium carbonate with a particle size of 11~13 μm (400~1 250 mesh) | Improve the hardness and strength of the material as well as its dimensional stability and reduce production costs |
Coupling agent | Commonly used coupling agents include silane coupling agents, titanate coupling agents, and maleic anhydride grafted modified high-density polyethylene (J-607) | Solving the problem of poor interfacial compatibility between highly polar wood and weakly polar plastics |
Stabilizer | Composite lead salt stabilizer, organic tin stabilizer, calcium zinc stabilizer | Prevent PVC resin from decomposing during processing and extend the service life of the product |
Plasticizers | Commonly used plasticizers include dibutyl phthalate (DBP), dioctyl phthalate (DOP), dioctyl sebacate (DOS), etc. | Improve its processing performance |
Lubricants | Commonly used lubricants include stearic acid, polyethylene wax, lead stearate, polyester wax, ethylene bis fatty acid amide, paraffin, oxidized polyethylene wax, etc. | Improve melt fluidity and surface quality of extruded products |
Colorants | Commonly used colorants include yellow, red, black, white, etc. | Change the color of a substance |
Foaming agent | There are two commonly used foaming agents: endothermic foaming agents (such as sodium bicarbonate) and exothermic foaming agents (such as azodicarbonamide AC). | Improves the impact performance and ductility of the material and greatly reduces the density of the product |
UV stabilizers | Light shielding agent, UV absorber, quencher, free radical scavenger | Prevent polymer degradation or loss of mechanical properties in composite materials |
Others | Antimicrobial Agent | Inhibit and kill surface bacteria to prevent the growth of microorganisms |
After understanding the specific material composition of wood plastic wall panels, let's take a look at their comprehensive physical and chemical properties.
Wood plastic wall panels have a variety of excellent physical properties, including the following:
1.1 Good strength
Wood plastic wall panels have high strength, can withstand large external forces, and are not easy to deform or damage.
1.2 High hardness
Its surface hardness is high, usually 2 to 5 times that of wood, and can resist certain wear and tear and external impact.
1.3 Anti-slip
Anti-slip treatment is added to the surface to make it more anti-slip and textured.
1.4 Wear resistance
After special treatment, wood plastic wall panels are highly resistant to wear and tear and are not easily damaged by daily use.
1.5 Not easy to crack
Due to different composite materials and advanced processing technology, cracking is difficult.
1.6 No insect bites
Unlike pure wood materials, wood-plastic wall panels do not contain nutrients and are not easy to attract insects, so they are more resistant to insects.
1.7 Low water absorption
The water absorption rate of wood-plastic wallboard is low. It has no affinity with water and is not easily swollen or deformed by moisture.
1.8 Anti-aging
The specially treated wood-plastic wall panels have good anti-aging properties, which enables them to maintain the stability of the finish and structure during long-term use.
1.9 Anti-corrosion
Wood plastic wall panels are not susceptible to moisture and corrosion, and can still maintain good performance in a humid environment.
1.10 Anti-static and anti-ultraviolet
After special treatment, it can effectively resist the damage of static electricity and ultraviolet rays, maintaining a beautiful surface and stable performance.
1.11 Insulation, heat insulation, flame retardant
Wood plastic wall panels also have good thermal insulation properties and can isolate electric current. At the same time, they also have good thermal insulation properties to maintain the stability of indoor temperature.
In addition, by adding flame retardants, they also have good flame retardant properties, which can delay the spread of fire in the event of a fire.
1.12 No toxic substances
No toxic substances or hazardous chemicals are contained, and no harm is caused to the environment and human health.
1.13 Recyclable
As an environmentally friendly material, it is recyclable and meets our environmental standards.
1.14 Biodegradation
Some wood-plastic wall panel materials are biodegradable, reducing pollution to the environment.
Similarly, wood-plastic wall panels have a variety of chemical properties and can still maintain good appearance and properties when used in some low-acid and low-alkali environments.
2.1 Acid and alkali resistance
Wood plastic wall panels have good resistance to a variety of chemical substances and are not easily corroded by acids and alkalis.
2.2 Antibacterial property
After adding an antibacterial agent, it can effectively inhibit the growth of bacteria and mold and ensure environmental hygiene.
2.3 Stability
Under different temperature and humidity conditions, wood plastic wall panels can maintain chemical stability and are not easy to deteriorate.
2.4 Non-volatility
Wood plastic wall panels have the characteristics of low volatile organic compound release, so they are safer and more environmentally friendly during use.
After understanding the various characteristics of wood plastic wall panels, you also need to understand their advantages and limitations to better understand whether it is suitable for different purposes.
Strong plasticity: Wood-plastic wall panels are rich in colors and can be customized according to personal preferences, fully reflecting your personalized style.
Easy installation: Secondly, its installation does not require complicated procedures, saving operation time and cost, and it has strong processability and is easy to nail, plan, saw, and drill.
Good sound absorption effect: In addition, it also has a good sound absorption effect and good energy-saving performance, and indoor energy saving can reach more than 30%.
Long service life: Wood-plastic wall panels have a long service life. According to relevant surveys, they can be used for 10-50 years.
Uneven quality: There are many types of wood-plastic wall panels in the building materials market, and the quality of products from different merchants varies. A background investigation and sample quality inspection are required when purchasing.
Brittle texture: Although it can withstand daily minor collisions and pressure without deformation, it will still be damaged if it falls from a height or is hit by heavy objects.
Wood plastic wall panels are most widely used in the building materials industry, mainly for indoor and outdoor wall decoration, ceilings, etc. Its waterproof, moisture-proof, insect-proof, and termite-proof properties make it an ideal building material.
