Furniture board and preparation method thereof

Abstract

The invention belongs to the field of furniture, and discloses a preparation method of a furniture board. The method comprises the following steps: adding nanometer silicon dioxide into ethylene glycol for dissolving; adding purified terephthalic acid, and carrying out an esterification reaction to obtain an esterified product; mixing diethylene glycol with dibasic acid, adding a titanium catalyst, and carrying out a polymerization reaction to obtain a prepolymer; adjusting temperature and pressure, and carrying out a hybrid reaction on the esterified product and the prepolymer to obtain a PETraw material with a melting point of 110-120 DEG C; carrying out melt extrusion on the PET raw material, and carrying out needling, hot bonding or spinning melting treatment to obtain a PET non-wovenfabric; pretreating the PET non-woven fabric with the melting point ranging from 110 DEG C to 120 DEG C and a PET non-woven fabric with a melting point ranging from 225 DEG C to 260 DEG C to obtain aPET non-woven fabric pre-material; and cutting, hot-pressing and cooling the pre-material to obtain the furniture board. The preparation method is simple and stable in process and suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of furniture, and in particular relates to a furniture board and a preparation method thereof. Background technique [0002] According to statistics, furniture pollution has become the third largest pollution source after construction pollution and decoration pollution in the living and office environment. Furniture based on wood-based panels often emits formaldehyde to varying degrees during use, which is closely related to its main body consisting of wooden panels and is unavoidable. First of all, wood itself contains a certain amount of formaldehyde because of the needs of its own life activities. Secondly, wood-based panels are bonded together with glue. If the glue is not fully reacted during synthesis, free formaldehyde will remain. Because of these two reasons, traditional wood-based furniture products cannot solve the problem of formaldehyde release. [0003] In addition, the wood panels used in traditional...

Because of these two reasons, traditional wood-based furniture products cannot solve the problem of formaldehyde release

[0003] In addition, the wood panels used in traditional furniture, such as high-density fiberboard, low-density fiberboard, particle board (particle board), oriented strand board, plywood, etc., although some preservatives and additives for various functional purposes The problem of the material itself also cannot completely solve the problem of water resistance. It will deform when it gets wet, shrink when it dries, and it will also be eroded by termites.

[0004] In order to effectively solve the problem of formaldehyde release and water resistance in furniture materials and the problem that polyester materials cannot be used in furniture because of insufficient hardness
