It is often used for indoor building and decoration of various furniture and cupboards. Some panels, walls, cabinets, cabinet laminates, etc.
The melamine impregnated bond paper veneering comprises a direct veneering and a compound veneering, wherein the direct veneering refers to a process of directly pasting the melamine impregnated bond paper on a board blank of the ecological board, and the compound veneering refers to a process of firstly pasting the melamine impregnated bond paper on a poplar skin and then pasting the poplar board on the board blank. However, the traditional melamine impregnated bond paper has poor appearance quality after being laminated, and is easy to have the problems of dry flower, wet flower, surface pore, bright amount, bubbling, layering, no demoulding, plate warping, cracking, no wear resistance, no pollution resistance, no scratch resistance, no sun resistance, no steam resistance and the like.

In view of the above, the invention provides a melamine impregnated bond paper facing process, which solves the problems of dry flowers, wet flowers, surface pores, brightness, bubbling, layering, no demoulding, warping, cracking, no wear resistance, no pollution resistance, no scratch resistance, no sun resistance, no steam resistance and the like after facing.
On one hand, the invention provides a melamine impregnated bond paper overlaying process, which comprises the following steps:
step 1: scraping putty on the surface of the poplar: placing the poplar bark into a putty scraper for putty scraping, and adjusting the color of putty according to the color of the poplar bark, wherein the thickness of the putty takes the color of the poplar bark which can be seen clearly as a standard;
step 2: sanding the poplar surface: the poplar skin after scraping greasy completion with poplar face is put into the grinder and is sanded, according to poplar skin thickness adjustment grinder, the used abrasive band of sand light is 180 meshes or 240 meshes, sand light hourly speed: 75-100 m/min;
and step 3: edge sawing: placing the plate blank after the sanding of the poplar surface into an edge sawing machine for edge sawing operation;
and 4, step 4: hot-pressing and re-pasting: adhering the melamine impregnated bond paper to poplar wood veneer, and then putting the poplar wood veneer into a hot press for hot pressing, wherein the re-adhering hot pressing pressure of the hot press is 5-6 Map, the re-adhering hot pressing temperature is 95-100 ℃, and the re-adhering hot pressing time is 480-660 seconds; and (3) maintaining the pressure after the re-pasting hot pressing is finished, wherein the pressure maintaining value of the hot press is adjusted to 0-2 Map, the pressure maintaining temperature is 95-100 ℃, and the pressure maintaining time is 60-120 seconds.
Compared with the prior art, the melamine impregnated bond paper composite veneering process has the beneficial effects that:
the problems of dry flower, wet flower, surface pore, brightness, bubbling, layering, no demoulding, cracking and the like after veneering are solved, and the appearance quality of the ecological plate is improved.
Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The phenomenon of dry flower after the surface of the traditional melamine impregnated bond paper is coated refers to the fact that opaque white flower spots exist on the surface of a product, and is mainly caused by insufficient fluidity or insufficient flowing time of the bond paper. The phenomenon of wet-flower is also called water stain, which means that the surface of a product has fog-like marks, and the main reasons are that external water is brought to a plate, the content of urea glue is too high, and the opacity of the cured urea glue is similar to 'wet-flower'. The phenomena of surface pores and bright stars mean pinhole-like defects on the surface of a product, and the main reasons are caused by insufficient fluidity of glue and the penetration of urea glue to the surface. The phenomena of bubbling and layering refer to abnormal bulges on the surface of a product caused by gas contained in the product, and the separation phenomenon of the adhesive film paper and an ecological plate or the adhesive film paper is seriously caused, and the main reason is the phenomenon of plate explosion caused by overhigh hot pressing temperature and overlong time. The phenomenon of no demoulding refers to that the product is partially or completely adhered to a steel plate in the hot pressing process, and the reasons are short hot pressing time, incomplete resin curing due to low temperature or partial low temperature of a hot pressing plate, overhigh water content of a plate blank, overlarge gluing amount of glue film paper, overhigh volatile matter, unclean steel plate surface and the like. The cracking phenomenon refers to the generation of reticular or linear fine cracks on the surface of a product, and the main principle is that the structural deformation of the adhesive film paper glue after solidification is too small to cause mismatching with the expansion with heat and contraction with cold of a plate blank, cracks are easily generated after cooling, the closing speed of a hot press is too high, and the impact force on the adhesive film paper is large.
In order to solve the problems, the invention provides a melamine impregnated bond paper coating process, which comprises the following steps:
step 1: scraping putty on the surface of the poplar: placing the poplar bark into a putty scraper for putty scraping, and adjusting the color of putty according to the color of the poplar bark, wherein the thickness of the putty takes the color of the poplar bark which can be seen clearly as a standard;
step 2: sanding the poplar surface: the poplar skin after scraping greasy completion with poplar face is put into the grinder and is sanded, according to poplar skin thickness adjustment grinder, the used abrasive band of sand light is 180 meshes or 240 meshes, sand light hourly speed: 75-100 m/min;
and step 3: edge sawing: placing the plate blank after the sanding of the poplar surface into an edge sawing machine for edge sawing operation;
and 4, step 4: hot-pressing and re-pasting: adhering the melamine impregnated bond paper to poplar wood veneer, and then putting the poplar wood veneer into a hot press for hot pressing, wherein the re-adhering hot pressing pressure of the hot press is 5-6 Map, the re-adhering hot pressing temperature is 95-100 ℃, and the re-adhering hot pressing time is 480-660 seconds; and (3) maintaining the pressure after the re-pasting hot pressing is finished, wherein the pressure maintaining value of the hot press is adjusted to 0-2 Map, the pressure maintaining temperature is 95-100 ℃, and the pressure maintaining time is 60-120 seconds.
The invention strictly controls the hot pressing pressure, the hot pressing temperature and the hot pressing time, and then carries out pressure maintaining treatment after the hot pressing is finished, thereby solving the problems of dry and wet patterns, surface pores, bright quantity, bubbling, layering, no demoulding, cracking and the like after the surface is pasted, and improving the appearance quality of the ecological plate.
The techniques not described above are common general knowledge of the skilled person. The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
