As shown in fig. 1, the present invention provides an embodiment of a novel environment-friendly composite board.
This novel environmental protection composite board includes: the plate core 1 and a surface sheet 2 fixed to at least one surface of the plate core 1, and a thermal adhesive film 3 is provided between the surface sheet 2 and the plate core 1.
Specifically, the core is selected according to the application of the core, such as particle board, fiber board, solid wood particle board, and the embodiment is described with a honeycomb core, such as an aluminum honeycomb core. The surface sheet 2 is selected according to the application, and stainless steel, PVC, color steel, etc. may be used. The thickness of the thermoadhesive film 3 is selected according to the nature of the adhesive material and may generally be between 0.1 and 05 CM. The thermal bonding film may be an existing hot melt adhesive, such as EVA glue, PA glue, PES glue, PO glue, or TPU glue. The thermal bonding film can be flatly laid on two or two surfaces of the plate core for fixing the surface layer sheet material, and also can be flatly laid on the surface layer sheet material fixed with the plate core.
During manufacturing, the thermal bonding film 3 is arranged between the board core 1 and the surface sheet 2, the board core 1 and the surface sheet 2 are uniformly clamped and placed in a certain temperature place, the thermal bonding film is melted, the board core 1 and the surface sheet 2 are placed and cooled, the thermal bonding film is solidified, and the board core 1 and the surface sheet 2 are bonded to form the required composite board. The specific melting temperature and cooling temperature are determined according to the selected hot melt adhesive characteristics, for example, the cooling temperature can be normal temperature. When the thermal bonding film is melted to the curing process, uniform pressure is applied to all parts of the surfaces of the board core 1 and the surface layer sheet 2 and is kept until the hot melt adhesive is cured, so that the flat surface of the composite board obtained by compounding can be ensured. A small amount of hot melt adhesive is present between the skin sheet 2 and the honeycomb panel core fixing surface.
When the composite board is manufactured, only the thermal bonding film with uniform thickness is laid between the board core 1 and the surface layer sheet 2, and the gluing operation is not needed, so that the phenomenon that the board core and the surface layer sheet are poor in bonding stability due to uneven distribution in the gluing process is avoided, the process difficulty is reduced, and the bonding reliability of the composite board is improved.

The honeycomb panel core fixing surface 11 is provided with the accommodating groove 12, when the thermal bonding film is melted, because the thermal bonding film has a certain thickness, part of the hot melt adhesive enters the accommodating groove 12, so that the bonding area of the thermal bonding film and the honeycomb panel core can be increased, and the bonding strength is further improved.
In order to increase the contact area between the thermal bonding film and the surface sheet 2, the accommodating groove 12 is provided with an overflow glue opening 13, the overflow glue opening 13 can discharge redundant hot melt glue from the accommodating groove 12, the hot melt glue discharged from the overflow glue opening 13 is contacted with the surface sheet 2 and is connected with the hot melt glue in the accommodating groove 12 into a whole, the contact area between the honeycomb plate core and the surface sheet 2 can be increased after curing, and the bonding reliability is further improved.
If necessary, a guide groove (reference numeral) for engaging with the honeycomb core fixing surface may be provided on the adhesive surface of the skin sheet 2. Redundant hot melt adhesive overflows from the honeycomb panel core fixing surface and contacts with the guide slot when the hot melt adhesive is manufactured, and when the hot melt adhesive is solidified, the contact area of the hot melt adhesive and the surface layer sheet 2 is increased, so that the effect can be achieved.
In order to avoid the waste of the thermal bonding film, the thermal bonding film is provided with a network consistent with the fixing surface of the honeycomb plate core, as shown in fig. 5, when the honeycomb plate core is fixed, the thermal bonding film is superposed with the fixing surface of the honeycomb plate core, so that the fixing effect is achieved, the consumption of the thermal bonding film can be reduced, and the honeycomb plate core fixing device is more environment-friendly.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
