Description
Technical Field
The invention relates to the technical field of plate processing, in particular to a melamine veneer compounding process.
Background
The melamine veneer which is faced by the melamine impregnated paper has a plurality of advantages. For example, various patterns can be printed on the melamine impregnated paper at will, and the color is bright; the melamine veneer has high surface hardness, wear resistance and heat resistance, and can resist the corrosion of common solvents such as acid, alkali, grease, alcohol and the like; the melamine veneer has smooth and clean surface, is easy to maintain and clean and has better weather resistance. Therefore, melamine impregnated paper is widely used for finishing various artificial boards such as fiber boards and particle boards. The artificial board after finishing can be used for manufacturing various furniture, cabinets and the like. After the surface of the melamine impregnated paper is added with the wear-resistant material, various reinforced floors can be manufactured. However, the melamine veneer also has some problems in use, such as the edge sealing is easy to break, and the color of the edge sealing cannot be completely consistent with the surface. In addition, some artificial boards such as stone-plastic boards, glass-magnesium boards, wood-plastic boards, foam boards, gypsum boards, inorganic cement boards and the like cannot be directly faced with melamine impregnated paper. Although the ecological board can be directly faced by the melamine impregnated paper, the inferior rate of the direct facing by the melamine impregnated paper is higher because the performance difference of the natural wood is larger. In addition, melamine impregnated paper cannot finish various profiled surfaces such as wood doors, decorative moldings, and the like.

Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments are briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without inventive efforts, wherein:
fig. 1 is a flow chart of a preferred embodiment of the melamine veneer compositing process of the invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a melamine veneer compositing process is provided, which comprises the following steps:
(1) the surface layer and the bottom layer are connected together through a hot pressing process, and the curing process between the surface layer and the bottom layer is completed simultaneously to obtain the laminated coating material, wherein the surface layer is melamine impregnated paper, and the bottom layer is kraft paper, parchment paper or non-woven fabric. Because the kraft paper, parchment paper or the non-woven fabrics of bottom are continuous coiled materials, through the hot pressing back the bottom can be with a slice melamine impregnated paper links together to the lamination cladding material also becomes the coiled material, and this coiled material setting can make things convenient for follow-up roll squeezer with the compound of lamination cladding material and base material board.
(2) The substrate plate 1 is firstly placed on the positioning conveyor 2 through a plate pushing machine or a plate sucking sports car, and the positioning conveyor positions the substrate plate. And after positioning, the upper surface of the base material plate is coated with glue by a glue coating machine 3. And (2) putting the laminated coating material 4 obtained in the step (1) on a constant-tension unreeling roller 5, entering a gap between an upper pressing roller 7 and a lower pressing roller 8 through a transition roller 6, entering a gap between the upper pressing roller and the lower pressing roller through a feeding roller table 10, and compounding the laminated coating material with the laminated coating material under the pressure action of the upper pressing roller.
