同時に満足する化粧板全製造することは困難である。On the other hand, there is also a method of overlaying a paper impregnated with a thermosetting resin on the decorative veneer. Although a satisfactory design can be obtained by this method, the surface hardness is inferior to that obtained by WPC treatment, and the crack resistance is also insufficient. In general, crack resistance and surface hardness are contradictory properties, so
Using the conventional overlay method, in which a sheet of resin-impregnated paper is simply hot-press molded onto a decorative veneer, it is difficult to produce a complete decorative veneer that satisfies both properties of crack resistance and surface hardness at the same time.

The structure consists of a decorative veneer bonded to a substrate via an adhesive, and a thermosetting i resin having an elongation in the cross direction of 20% or more after curing of the resin.
Layer v1 fat-impregnated paper, and then apply the same elongation to 10q on top of this.
It is characterized by stacking thermosetting resin-impregnated papers having a hardness equal to or less than b and simultaneously molding them under heat and pressure.

。First of all, the decorative veneers used in the present invention include decorative veneers of white wood such as cedar and cypress, which have a golden texture, as well as wood mallets that cannot be subjected to WPC treatment due to the presence of resin curing inhibitors in the wood. A decorative veneer made of softwood such as Spanish mackerel or cedar or hardwood such as zelkova is used. These decorative veneers are bonded onto the plywood substrate by conventional methods. As the adhesive, a mixed adhesive consisting of a thermosetting resin adhesive and a thermosetting resin bonding agent, such as a mixture of modified synthetic rubber latex and amino resin,
Alternatively, modified rubber latex or the like is suitable. [Thermosetting resin bonded to a decorative veneer by heat and pressure)] β-impregnated paper is thin paper, nonwoven fabric, synthetic paper, etc. with melamine resin or unsaturated polyester resin.

いてそのクロス方向の伸びが影響する。A semi-cured material impregnated with acrylic resin, diacryl phthalate resin, etc. is used. Here, the impregnated paper for the lower layer should be one with an elongation rate in the cross direction of 20 or more after resin curing, and the impregnated paper for the upper layer should be one with an elongation rate of 10 or less in the cross direction after resin curing. Use. The elongation in the cross direction refers to the elongation in the direction perpendicular to the longitudinal direction of the fibers in the direction in which the fibers of the impregnated paper are arranged. Generally, when impregnated paper is thermocompression bonded to a decorative veneer, the cross direction of the impregnated paper is aligned with the width direction of the board. Therefore, in order to improve the board width accuracy, the elongation rate of this impregnated paper is influenced by its elongation in the cross direction.

After curing under curing conditions for a pressing time of 1 o, a tensile test was conducted at a tensile rate of 10 m/min using a test piece with a width of 15 m and a thigh length of 150 + m* with the cross direction as the long axis direction.
When elongation at break is measured, it is given as the ratio of the length at break to the length before the test. The basis weight of thin paper, nonwoven fabric, synthetic fiber paper, etc. used as a base material for impregnation is 25~
Use something about 40g and 2 arms. If the basis weight of the base material for impregnation is less than 25 YAI, the amount of resin to be impregnated and retained in the base material will be insufficient and the desired performance cannot be imparted. At? In the above case, the amount of resin impregnated will be excessive and the appearance peculiar to natural products of the υ decorative veneer will be significantly impaired. In general, both surface hardness and crack resistance are proportional to the amount of resin impregnated, but from the viewpoint of impregnated paper cost and workability, it is recommended to impregnate the above-mentioned impregnated base material with thermosetting resin. The amount is in the same range as conventionally commonly used plywood and decorative veneer, that is, 2
00~300t/lr? is sufficient.

極めて大きな利点を有する。In the manufacturing method of the present invention described above, thermosetting resin-impregnated paper with a cross-direction elongation rate of 20% or more after curing is used as the impregnated paper for the lower layer and is hot-press molded on the decorative veneer, so there is relatively large shrinkage. It is held on the surface of the decorative veneer and acts to prevent dimensional changes due to expansion, while also relaxing the transmission of stress to the decorative veneer in response to external forces. Furthermore, a thermosetting resin-impregnated paper with an elongation rate of 10 or less after curing is used as the upper layer impregnated paper, and is laminated on the lower layer impregnated paper and hot-press molded to ensure high surface hardness and overall crack resistance. Decorative laminates with excellent properties and surface hardness can be manufactured. Furthermore, the manufacturing method of the present invention is comparable in workability to the conventional method of overlaying a single impregnated paper, and it is possible to obtain a decorative board with significantly superior quality performance. This has extremely large practical advantages.
