In some embodiments, the PET composite impregnated bond paper veneer comprises, from top to bottom, a PET film layer 4, a glue layer 3, a thickness adjusting layer 5, an impregnated bond paper layer 2, a core layer 1, a thickness adjusting layer 5, and an impregnated bond paper layer 2 in sequence, wherein the PET film layer is only disposed on the surface of the impregnated bond paper on one side, during production, only the upper impregnated bond paper layer is subjected to roller coating with hot melt adhesive, and then the PET film is flatly attached, and the veneer with such a structure is generally used in a scene where only one side of the veneer needs to be facing outward.
In other embodiments, the PET composite impregnated bond paper veneer comprises a PET film, 4, a glue layer 3, an impregnated bond paper layer 2, a thickness adjusting layer 5, a core layer 1, a thickness adjusting layer 5, an impregnated bond paper layer 2, a glue layer 3, and a PET film layer 1 from top to bottom in sequence, and both sides of the veneer with such a structure have PET films, that is, both sides of the veneer have better brightness and strength.
The PET composite impregnated bond paper veneer is prepared by the following steps:
s1, preparing a finishing layer: and sequentially paving a thickness adjusting layer and a layer of impregnated adhesive film on the upper surface and the lower surface of the core layer, determining the number of the buffer layers according to the thickness of the core layer, pressing and pasting the core layer by a hot press, wherein the pressing and pasting temperature of the hot press is 130-200 ℃, the unit pressure is 1.0-2.0 MPa, the hot pressing time is 15-60 s, and obtaining the impregnated adhesive film paper veneer through hot pressing. The pressing temperature, the pressing pressure and the pressing time are direct factors influencing the pressing effect. The hot pressing temperature can influence the curing reaction speed of resin, when the pressing temperature is too low, the melamine glue can not be cured completely, so that the bonding effect is reduced, when the pressing temperature is too high, the curing speed of the impregnated paper is too high, the cracking or dry-out phenomenon is easily caused, and when the temperature is 130-200 ℃, the curing speed is more proper. The pressure during hot pressing can promote the impregnated bond paper, the thickness adjusting layer and the core layer to be combined, the bonding performance is improved, when the pressure is too low, the flowing and the permeation of resin in the impregnated bond paper can be reduced, the bonding strength of the impregnated bond paper, the thickness adjusting layer and the core layer is reduced, when the pressure is too high, the mechanical performance of the core layer can be damaged, even the thickness of the core layer is changed, particularly when the pressure is applied to a particle board, the pressure is not too high, and when the pressure is 1.0-2.0 MPa, the better bonding effect is achieved. Under the fixed condition of temperature and pressure, hot pressing time is longer, and then the resin solidification is more abundant, but hot pressing overlength makes the resin solidification excessive easily, and elasticity descends, and hot pressing time is too short makes the solidification insufficient again, produces the sticky board phenomenon easily, influences product quality, is 15 ~ 60s when hot pressing time, has better curing effect.
S2, compounding of the PET film: cleaning the surface of the impregnated bond paper veneer through a blowing mechanism, ensuring that no dust or stain is on the surface of the impregnated bond paper veneer, melting glue through a glue melting mechanism, wherein the glue melting temperature is 110-130 ℃, the molten PUR hot melt adhesive is coated on the surface of the impregnated bond paper through a roller coating device in a roller coating mode, the coating thickness is 0.04-0.06 mm, then flatly pasting a PET film on the PUR hot melt adhesive through a mirror surface sweeping roller, solidifying and maintaining, wherein the maintaining condition is that the temperature is lower than 30 ℃, the humidity is 50-70%, and maintaining is carried out for 48-60 h to obtain the PET composite impregnated bond paper veneer.
In the step S2, the temperature of the glue coating roller in the roller coating device is 110 to 120 ℃ to ensure that the PUR hot melt adhesive can be in a molten state for better gluing, and the temperature of the mirror sweeping roller is 120 to 130 ℃, which is higher, so that the excess PUR hot melt adhesive can be scraped off from the surface of the impregnated adhesive film paper to obtain an adhesive layer with a set thickness, thereby obtaining a veneer with a consistent thickness.
It should be noted that step S2 needs to be performed in a dust-free workshop, and the requirements on the ambient temperature and humidity are high, and the ambient temperature needs to be controlled to be 25 ℃ and the humidity needs to be 50-70%, so that the pasting process can be smoothly performed, and the PET composite impregnated bond paper veneer with firm adhesion and good appearance effect is obtained.
It should be particularly noted that, in the step S1, the thickness of the impregnated bond paper facing board needs to be strictly controlled, and it is necessary to ensure that the thickness deviation is smaller than 0.15mm, so that the thickness deviation of the core layer is required to be small, mainly because the gluing thickness of the PUR hot melt adhesive is only 0.04-0.06 mm, if the thickness deviation is too large, the inaccuracy of the thickness of the PUR hot melt adhesive in the step S2 is easily affected, and the thickness of the PUR hot melt adhesive directly affects the gluing effect, and finally affects the product quality, so that the thickness of the core layer is kept within the deviation range by additionally attaching the thickness adjusting layer on the surface of the core layer.
The preparation method of the PET composite impregnated bond paper veneer has the advantages of few processes, simple operation and easy realization, and can be completed through the hot-pressing and pasting processes, and the prepared PET composite impregnated bond paper veneer not only has the appearance effect of a UV veneer, but also has various physical and chemical properties superior to those of the UV veneer.
