Description

[Detailed Description of the Invention] [Objective] In a method of manufacturing laminated decorative wood veneers using laminated decorative veneers, in particular, to eliminate unevenness during wiping processing during finishing and achieve a finish that gives a hard feel. The purpose is to

[Background Art] Laminated decorative veneers are manufactured by stacking an appropriate number of raw material veneers with an adhesive, sandwiching them between molds and pressing them together to form a flitch, and slicing this. This sliced veneer is usually about 0.3 to 0.6 mm in diameter, and is used as a decorative wood board by pasting it onto a substrate as a veneer.

After pasting the laminated decorative veneer on the board,
Wiping is performed on two sides, but in the case of conventional laminated decorative veneers, uneven wiping occurs due to differences in the quality of the raw wood veneers, which deteriorates the quality of the precious wood decorative veneers.

This invention was made in view of the following circumstances.

Note that the wiping treatment here means applying a wiping agent to the surface of the laminated decorative veneer and rubbing or brushing the applied surface with a cloth. The wiping agent is a mixture of a solvent, a resin, and a pigment.

[Disclosure of the Invention] The present invention provides a method for removing the adhesive, which is attached to a substrate before wiping.
It is characterized by applying a water-soluble acrylic resin emulsion to the surface of the decorative veneer, drying it, and then sanding it.

The conventional laminated decorative veneer used here can be used as is. Conventional wiping agents are also sufficient. The wiping process may be performed using a conventional method. The thickness of the laminated decorative veneer also follows the usual method. Approximately 0.3~Q, 5mm
Use one with a certain thickness. The board is also made of plywood, which has been used in the past.

To manufacture decorative wood veneers, laminated decorative veneers are first processed. Then, it is attached to the substrate. Next, primary sanding is performed. In this case, approximately 200-grit sandpaper is used. However, the purpose is not to limit the use to sandpaper, and other methods may be used as long as sanding can be performed.

And it is not the intention to limit the number of sandpapers.

The water-soluble acrylic resin emulsion described above is applied to the sanded surface. There are no limitations on this water-soluble acrylic resin emulsion. The concentration is also arbitrary. Coating conditions are adjusted depending on the concentration or desired coating thickness. After applying the water-soluble acrylic resin emulsion, it is dried. Drying conditions are also arbitrary. After drying, perform secondary sanding. Sandpaper is 2
Use something around number 00. This is not intended to limit sanding.

After the above pretreatment, a normal wiping process is performed. Next, explanation will be given based on an experimental example.

Experimental example I conducted an experiment using the contents in the table below.

In the above table, processing agent A is a water-soluble acrylic resin emulsion, and the product name is indicated for each. The thickness of all raw material veneers was 0.3 m.

For the first sanding, No. 200 sandpaper was used, the amount of treatment agent applied was 120 to 150 g/cd, and the drying was at SO"C for 1 hour. For the second sanding, No. 200 sandpaper was used.

After sanding, wiping was performed by a conventional method, and when the difference in wiping unevenness was compared with that of an untreated sliced veneer, good results were obtained for Nos. 3, 4.7, and 8 as examples.

[Effects] This invention is characterized in that before wiping, a water-soluble acrylic resin emulsion is applied to the surface of the laminated decorative veneer adhered to the substrate, dried, and sanded, thereby reducing uneven wiping during wiping. As soon as the
A hard feel has been added to the veneer, making it possible to manufacture high-quality decorative wood veneers.
