Abstract

PURPOSE:To obtain a decorative board having anti-slip effect without changing the beautiful appearance thereof, in preparing the decorative board by laminating wooden veneer to a base board, by adding an oleoresin to a paint. CONSTITUTION:Wooden veneer comprising teakwood or cherry wood is laminated to a base board such as plywood or inorg. board and an oleoresin obtained by injuring a pine tree to a paint such as a polyurethane resin paint to perform painting. Thus obtained decorative board has excellent anti-slip effect.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of manufacturing a decorative board in which a wooden veneer is adhered to a substrate and a paint made by adding oleoresin is applied.

[Background technology]

Conventionally, it has been a widely known and publicly used technique to apply paint to protect the surfaces of flooring materials, edge decks, etc. and maintain their aesthetic appearance, but when paint is applied, a resin layer is formed and the slipperiness is However, this has resulted in the problem of slipping when walking, sometimes causing falls and injuries.

Therefore, in order to improve such defects, there is a method of roughening the surface of the resin layer by abrasive treatment after painting, or adding inorganic substances such as slag particles to the paint to create fine irregularities on the surface of the resin layer. Methods have been tested and some have been put into practical use.

However, such improved technology not only has the drawbacks of damaging the resin layer and causing frequent occurrence of top*'6 on the coating equipment, but also has the drawback that it does not fully achieve its original purpose of preventing slipping. Was.

[Purpose of the invention]

The present invention aims to eliminate all of the drawbacks of the conventional decorative laminate manufacturing method described above, provide society with a decorative laminate manufacturing method that can effectively prevent slippage, and thereby contribute to the development of this industry. It is something to do.

[Structure of the invention]

Hereinafter, the method for manufacturing decorative plywood of the present invention will be described in detail.

The present invention can be applied to a substrate such as plywood, inorganic board, chip board, particle board, insulation board, metal plate, etc. with a thickness of 0.2% to 5% obtained from teak wood, backing material, etc.
．． A 0x wood veneer is pasted with an area resin adhesive, a pheno-A/resin adhesive, a -urethane resin adhesive, etc., and a polyurethane resin paint and polyester μ are applied to the front and surface of the wood veneer. A decorative board is obtained by adding oleoresin, a viscous liquid obtained by streaking a standing tree of the genus Pinus, to a paint such as a resin paint.

Turbentin obtained by steam distillation of oleoresin has an appropriate degree of polymerization and good compatibility with paints, so it is easy to use and has an excellent anti-slip effect.

Furthermore, even when rosin, which is a residue after steam distillation of oleoresin, is added to the paint, the anti-slip effect is excellent.

Hereinafter, the effects of the present invention will be explained based on practical examples.

Example 1 A polyurethane paint 1 in which a paint with the following formulation was applied to the surface of a wooden veneer attached to plywood and its friction coefficient was measured.
00 parts Oleoresin 10 parts Example 2 The conditions were the same as in Example 1, and the formulation was as follows.

Polyurethane paint 100 parts Turventin 6 parts ! i1! Example 3 Ordinance 3 Same as Example 1, the formulation was as follows.

Polyurethane paint 100 parts Rosin 7 parts Comparative Example The conditions were the same as in Example 1, only the polyurethane paint was applied.

By adding only a small amount to i-paint, it exhibits an outstanding anti-slip effect and has the effect that the aesthetic appearance of the resin layer does not change at all.

Claims (5)
