Description
Technical Field
The invention belongs to the field of furniture, and particularly relates to a furniture plate and a preparation method thereof.
Background
According to statistics, furniture pollution becomes the third major pollution source after relay building pollution and decoration pollution in the current residential and office environments. Furniture using artificial boards as base materials often emit formaldehyde outwards to different degrees in the using process, which is closely related to and unavoidable with the wooden boards formed by the main bodies of the furniture. First, the wood itself contains a certain amount of formaldehyde as required by its own vital activities. Secondly, the artificial boards are bonded together by using glue, and free formaldehyde remains if the reaction is insufficient during glue synthesis. For these two reasons, the conventional furniture products using wood as a raw material cannot solve the problem of formaldehyde emission.
In addition, although some wooden boards such as high-density fiberboard, low-density fiberboard, particle board (particle board), oriented structure chipboard, plywood and the like are selected for the traditional furniture, the preservative and additives with various functions and purposes are added in the manufacturing process, the problem of waterproofness cannot be completely solved due to the problems of the materials, and the wooden boards can deform when being wetted and shrink when being dried and can be corroded by termites.
The problem of formaldehyde release and water resistance in furniture materials and the problem that polyester materials cannot be applied to furniture due to insufficient hardness are solved.
Therefore, it is urgently needed to develop a PET sheet applicable to furniture.
