Description

[Detailed description of the invention] This invention relates to a method for manufacturing a decorative fist plate.

A plurality of material veneers are bonded by hammering and pressure using a mounting agent to obtain an assembled frift, and this assembled material veneer is sliced in a direction intersecting the product NIfi to cut each of the material veneers [
In the method of obtaining S-finish decorative car boards in which ji resembles the grain pattern of natural wood, the summer wood part t-
To express this, the conventional method has been to color the veneer of the material in the same color as the coloring agent used for gluing the material veneer together, and to express the summer wood part with the cut surface of this colored stain. There is.

However, the S-finished decorative wafer board obtained by such a method is not included in the above-mentioned collection [j! During the lamination and pressure ASS bonding process in the process of obtaining the 711-titch tube, the colored adhesive penetrates into the material layers located in the 70 and 70-way joints, and as a result, the resulting laminated decorative veneer is damaged as shown in the first factor. The boundary between the spring wood part 1 and the summer wood part 2, which is the colored layer ia, is blurred, and the boundary between the spring wood part and the summer wood part is clear, as seen in natural wood, giving a rich natural feel. I couldn't get summer wood.

In order to solve this problem, the present applicant previously proposed a method of providing a v-pv Q on one side of a spring material wire board in advance to prevent penetration of a colored board adhesive. That is, in this method, as shown in FIG. 2, before applying the colored adhesive to form the summer material part, adhesive No. 11F4A is applied to one side of the spring material veneer 3 using a low v coater 4. Applying 11
1. Next, stack 6 pieces of 1lIl pattern paper on one side and laminate them with 7vs board and pressure 111N! Wear it and see/
After forming L/1ii17, peel off the release paper 6 (fBl, C1 in the same figure), color it in a summer wood color with a coater 8, and apply a colored board adhesive 9 to the top surface (FIG. U) It is a thing. However, this method does not work! Since the process of forming 7 is required, productivity is low and manufacturing costs are high.

Therefore, an object of the present invention is to provide a method for manufacturing a decorative veneer that can reproduce the entire summer wood part l1IVc with a rich natural feel.

An example of Jin's invention is shown in the Yria device.

That is, in this method of manufacturing decorative veneer, a laminated decorative veneer with a grain pattern expressed on the surface of the material is obtained by the following steps.

(11 While transferring the material veneer 3' for spring material in one direction, apply the VC curing accelerator 10 and transparent adhesive 5 to the L side of this material laminated board 3', and heat press with hot row ν11 to Then, on top of this, a colored board jlAi9 colored in the color of summer wood is applied (Fig. 3).

f21 A plurality of spring material veneers 3' are laminated so that the applied surfaces of the In-era colored mold adhesive 9 are aligned in a predetermined direction, and l:EJIII is adhered at the unevenness 4112 to form an uneven assembly flitch 13.
(Figure [F] 1.cl).

+31 The obtained nine-concave-convex assembly frift 13 was sliced from a predetermined direction intersecting the laminated surface, and the above □
LIQ diagram 0. The cut surface of the colored plate adhesive 9 of the summer wood color and the spring wood color are expressed on the entire wood surface in a board-like manner, thereby obtaining a decorative car board 15. [F])).

The formation of the pre-arranged l+glue II 7' and the application of the colored adhesive 9 are carried out by the third factor (as shown in AIK, the material electric plate 3' is transferred in one direction and the curing accelerator lO is applied to one side thereof. , the application of the transparent adhesive 5, the application of the heat press and the colored board adhesive 9 are carried out continuously.The hardening accelerator IIA agent 10 accelerates the hardening of the transparent adhesive 5 during thermocompression bonding. , this curing accelerator 10 may be applied to the material electric board 3' at the same time as the transparent adhesive 5, or after applying the transparent adhesive 5 for a certain diameter. It is also possible to apply the adhesive 5 at VC.

The hardening accelerator IO is applied by mixing it with a suitable solvent and spraying it with a sprayer 14. As a curing accelerator, when using a urethane resin as the transparent adhesive 5,
Dibutyltin diquarate or the like can be used by dissolving it in ethyl acetate A/.

After applying the curing accelerator 10 and the transparent adhesive 5, press CI-A/11' while applying heat using a hot roller yli.
By pressing, the transparent adhesive 5 is cured, and an impermeable sheath IVM 7' is obtained on the raw material veneer 3'.

In this way, by using the curing accelerator 1O, the transparent adhesive 5 can be heated to Hot Row IV 11.7' Less Row A/
The sealing layer 7' can be easily formed by simply beat pressing while passing between l1' and l1'.
The processing tube for the material heavy plate 3 is carried out continuously. However, by using the Hoftro-11, there is no foaming of the Sea IV layer 7 compared to when heat pressing is performed with a press plate.
It is possible to obtain three uniform sea surfaces. It is preferable to use the same adhesive as the transparent adhesive 5 (for example, urethane resin) to ensure good bonding with the colored adhesive 9F'i and the spring 7'. .

Incidentally, as the spring wood material veneer 3', it is also possible to use a wood material veneer as is, but it is also possible to use a spring wood color dyeing bath (dye 1.0%
) may be dyed in advance and used as a spring wood colored veneer.

The thus obtained laminated decorative veneer 15 has one of the two parts of the summer wood part 2' completely separated from the spring wood part 1' by the sealing layer 7', as shown in @3 Fig. 1ElK. F
i It has a clear boundary, and the coloring adhesive 9 permeates into the spring wood part 1' due to pressure adhesion on the other unsealed surface 7L/, so the color becomes lighter as it moves away from the boundary, and it becomes like natural wood. This shows the subtle color change seen from spring wood to summer wood. □ As described above, the method for producing a decorative veneer of the present invention involves the formation of sea A/1ilB on one side of the spring wood material veneer and the summer wood color [abrasive 1I11! This process is carried out continuously with the application of S adhesive, and has the effect of being easy to reproduce at low cost.
