Application of Silent Plastic Wood Decking

By Seven Trust |

The development of indoor plastic wood decking as a product that follows the development trend will definitely become a mainstream product in the near future. But currently in China, plastic wood decking is mostly used outdoors. Even the plastic wood decking used indoors has a wooden feel and can be made into a variety of colors. However, because wood is a polar substance, its surface has partially unsaturated polar genes, while the plastic used to make WPC is a non-polar material, making the compatibility between decorative veneers and WPC deck base materials an urgent problem to be solved.

In terms of practicality, plastic wood decking is damaged due to creep deformation under a certain sustained force and releases different types of pollutants.These shortcomings limit consumer acceptance to a certain extent and hinder the promotion and application of plastic wood decking as indoor deck laying materials.In addition, the hardness of the plastic wood deck is relatively large. When people walk on the plastic wood deck, their shoes will make loud noises with their footsteps and the plastic wood deck.Even if someone is walking in the next room or in the public corridor, you can hear the sound. If there are multiple people walking around indoors at the same time, the overall noise generated will be very loud. Therefore, it is particularly important and urgent to solve the problem of loud or even noise when walking on plastic wood decks.

The existing technical solution is to set a cork pad on the deck. The cork pad serves as a silent pad.It can buffer the vibration generated between the deck and the ground as people walk, thereby reducing the noise generated by people walking on the deck and achieving a mute effect.However, cork silent pads are more expensive due to the material, and the cork material is not wear-resistant and easy to wear. In addition, since it is used for noise reduction and muting on the deck, the main function and function of the mute mat is to buffer vibration and absorb noise, but the noise absorption effect of cork material is not ideal.The new environmentally friendly silent plastic wood decking includes two upper and lower buffer layer structures, namely the upper buffer layer and the lower buffer layer. The upper buffer layer buffers and absorbs the impact and vibration of the plastic wood deck when people walk.The lower buffer layer provides secondary buffering and secondary absorption of the impact and vibration of the plastic wood decking on the ground.The double buffering and absorption effect ensures that the plastic wood deck has a good mute effect, effectively reducing the noise generated when people walk on the plastic wood deck. The thickness range of the upper buffer layer and lower buffer layer is reasonably set to ensure the mute effect while saving materials and ensuring that the overall thickness of the plastic wood deck is reasonable.

The lower buffer layer is made of silent material foam, so the rigidity and density of the lower buffer layer are lower, which is beneficial to better buffering the impact and vibration between the deck and the ground, and is beneficial to better absorbing noise.Compared with the middle material layer of traditional plastic wood decking, due to the higher proportion of plasticizer in the production formula of the upper buffer layer, the upper buffer layer has good flexibility, lower hardness, and higher elasticity.In addition, the thickness of the upper buffer layer is one, thereby ensuring the buffering and absorption effect of the upper buffer layer. This environmentally friendly silent deck provides more possibilities for the market while bringing warmth to people's lives.
