With the development of society and the continuous progress of science and technology, people have higher and higher requirements on the sound of the environment where they live, study and work, and more and more attention is paid to the impact and harm of noise on people. At present, the main method to reduce noise is to control by using sound-absorbing or sound insulating materials. As a new material, wood plastic composite material is widely concerned by people, which meets the needs of modern people for outdoor sound absorbing wall panel. As far as the material properties of the wood plastic composite material are concerned, there is no good sound-absorbing property of wood products, but how to enhance the sound-absorbing property of WPC wall panel products can refer to the compounding of wood and other kinds of sound-absorbing materials to maximize the sound-absorbing property of wood plastic composite materials, which is the research direction of wood plastic composite sound-absorbing materials. According to the characteristics and requirements of wood products, it will be the future development trend to design and manufacture WPC wall panel sound-absorbing materials.

Decorative Sound Absorbing Wall Panel
WPC Sound Absorbing Wall Panel Material Expands Application Scope

Has acoustic properties for a variety of wood composite materials research has shown that the sound absorption, decoration, environmental protection, practical, there are certain deficiencies in a specific environment, such as the porosity and the wood composite materials are better acoustic noise reduction features, its application range is limited by a mechanical strength on the physical properties. As a new environmental protection material, the wood plastic composite wall panel material has been gradually paid attention to in terms of sound absorption performance. The excellent characteristics and application range of WPC wall panel material can meet the requirements of sound absorption and noise reduction in a specific space. Compared with the formed wood acoustic material, wood plastic composite acoustic material should expand its application range.

Improve The Sound Absorption Performance Of The WPC Wall Panel

First of all, in terms of sound absorption materials, the porous sound absorption mechanism is fully utilized to improve the ratio of raw materials of WPC wall panel materials, so as to achieve the interpenetration of internal pores and improve its sound absorption performance. At the same time, the structural design of the plastic and wood composite materials can be carried out by imitating the preparation method of wood perforated sound absorbing wall panel boards commonly seen in the market. It is mainly based on the plastic wood composite material, the surface and back of the hole, so as to get the resonant sound-absorbing material, the shape of the surface hole can be round, strip, micro-hole, etc., through adjusting the size of the aperture, density degree and shape to adjust the sound-absorbing performance of the composite sound absorbing wall panel. The back of the slotting method is mainly in the back of the plastic wood board slot, slot types are mainly arc slot, trapezoidal slot, square slot and other types. The opening method can widen the absorption of WPC audio segments and improve the sound absorption performance of the high-frequency band, enhancing plastic wood plank decorative and sound absorption, but the performance of the product and process improvement and improve, hole groove on the structure of research and development, make its one-time moulding, avoid multiple processing, has the best sound absorption performance.

Secondly, wood plastic composite material as a system of new materials, the most widely used as outdoor products. Through the improvement of new technology, research and development of new technology and application of new structure, more products suitable for indoor use are developed, such as the floor, wallboard, decorative board, ceiling, doors and windows, furniture, sanitary ware and other series products with sound absorption performance. In addition to the application of traditional industries, can also be applied to some other industries, such as automotive interior parts, such as car door guard, door trim, trunk interior. In the future, the development of plastic-wood composite sound-absorbing materials can follow the development path of product production scale, composite diversification, sound-absorbing full-frequency, new structure, practical diversification and wide application fields, which will be the research focus of wood plastic composite sound-absorbing materials.
