Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for adhering a thin sheet of decorative wood veneer to a base material such as a wooden baseboard.

[Background technology]

For decorative purposes such as the door and the edges of the ceiling, decorative wooden boards were pasted onto the uneven wood and plywood. In this case, as shown in FIG. 3, adhesive lO is applied on plywood 9, decorative veneer 11 is placed on top of it, and! In Step 112, the decorative veneer 11 is pressed and bonded onto the base plate 9, but the decorative veneer 11 is pulled during the pressing process, causing the problem of the decorative veneer 11 cracking. Paper at 11.

The veneer was reinforced by lining it with cloth, etc., but when lining the nest board with paper, cloth, etc. or gluing it to plywood, wrinkles and bulges tend to occur in the nest board, and it is easy to fix once glued. The problem was that it wasn't.

[Purpose of the invention]

The object of the present invention is to provide a method for adhering sheet-like objects, which does not require reinforcement such as lining, and can adhere sheet-like objects such as nest board 9 paper to a base material such as plywood without causing cracks or tears. [Disclosure of the Invention] The method of adhering a sheet-like article according to the present invention includes sequentially placing an adhesive sheet and a sheet-like article on a base material, and bonding the sheet-like article at a temperature at which the sheet-like article is not bonded. The sheet-like material is pressed onto the base material to align the sheet-like material along the surface of the base material, and then the sheet-like material is adhered onto the base material by pressing under heat.

In this way, a sheet-like material is placed on one base material via an adhesive sheet, and after the sheet-like material is aligned with the surface of the base material, it is heat-pressed, so it is possible to use a sheet-like material such as a nest board, paper, cloth, etc. that has low strength. The base material may be a wooden base plate, etc., which may be flat or may be a base material with irregularities.

Examples of adhesive sheets used include adhesive sheets such as melamine resin sheets, paper, cloth, etc. impregnated with adhesive,
Furthermore, hot melt resin sheets etc. can be used. Next, the bonding method of the present invention will be explained in order. First, apply a predetermined amount of adhesive on the base material, then place the adhesive sheet on the
Furthermore, the entire thin sheet-like material is placed on this adhesive sheet. Next, the adhesive sheet and the sheet-like material are preformed by pressing them onto the base material at a temperature at which the sheet-like material is not bonded, for example, at a temperature such that the adhesive sheet and the sheet-like material are aligned along the surface of the base material. At this time, since the adhesive does not come into direct contact with the sheet-like object, there are fewer cracks due to tension, and air easily escapes, causing wrinkles.

There is little occurrence of blistering, and repairs can be easily performed@Furthermore, in this state, wrinkles or overlaps may occur in the adhesive sheet. Thereafter, the 7-piece autumn garment is pressed through the adhesive sheet under heat and adhered onto the base material.

In addition, in order to reduce the coefficient of friction between the adhesive sheet and the sheet-like object during the preforming process, it is recommended to apply fine powder of an adhesive of the same quality as the adhesive sheet to further prevent the sheet-like object from cracking or tearing. Preferably C. Furthermore, whether the base material is flat or has small irregularities,
Or, if high adhesive strength is not required,
An adhesive sheet is placed directly on the base material without applying any adhesive onto the base material, and after sprinkling fine powder of the same adhesive onto the adhesive sheet, a 7-tate-shaped object is placed on it, and the above-mentioned process is performed. Press in the same manner. The adhesive, adhesive sheet, and fine powder used must all have adhesive strength when pressed under heat in the final step. In this way, adhesives, adhesive sheets,
By using fine powder in combination, the adhesive strength is improved compared to the case of using adhesive alone or hot melt adhesive alone.

Next, the adhesion method of the present invention will be explained with reference to examples. Example 1: A wood veneer (150 x 300 sa++) with a thickness of 0.4 m was placed on a base plate 1 (base material) as shown in Fig. 1. In order to bond the melamine-polyamide adhesive, a predetermined amount of melamine-polyamide adhesive was first applied to the plywood by IK, then a 0.3 W+ thick polyester sheet hot melt adhesive was placed on the plywood, and homogeneous fine powder (particle size Micron) was sprayed on the surface and a nest board was placed on top of it. After that, the wood veneer is cold-pressed onto the base plate 1 using a sheet of hot melt adhesive to conform to the surface shape of the base plate 1, and then pressed at 150°C for 2 minutes to bond it. .

As a result, it was possible to bond without cracking, blistering, or overlapping, whereas conventional products would crack without backing.

Example 2: In order to continuously pressure bond the backing paper with a thickness of 0.1 to the wood nest board (base material), area-amino adhesive was applied to the upper surface of the Kl board 2 using a roll coater 3 as shown in Fig. 2. The agent 4 is applied, a melamine resin sheet 5 is placed on top of it, and a paper 6 is placed on top of it, and after being pressed with a cold roll 7, it is heated and pressed with a hot roll 8, and is glued together. 〇 [Effects of the Invention] According to the present invention, there is an effect that a sheet-like material such as a nest board 9 paper having low strength can be bonded onto a base material without reinforcing it.

Claims (2)

[Claims] (1) The adhesive sheet and the sheet-like material were placed on the base material in sequence, and the sheet-like material was pressed onto the base material at a temperature that would not allow the sheet-like material to be bonded, so that the sheet-like material was aligned with the surface of the base material. A method of adhering sheet-like objects, in which the sheet-like objects are then bonded onto the base material by pressing under heat. (2) Claim No. 1, wherein the base material surface is an uneven surface.
