Abstract

PURPOSE:To obtain a decorative material with woody feeling by a method wherein uniform resin treatment is done by sanding a surface, which is prepared by setting thermosetting resin. CONSTITUTION:Soft spring wood parts 2 are ground by subjecting the surface of wood based material (solid lumber, veneer, laminated lumber and the like of conifer) to a relief process or sandblasting. Next, resin 4 is filled in recessed by applying the thermosetting resin 4 such as urethane resin, polyester resin or the like on said surface and, after that set. After the setting, the whole surface is ground by sanding and finally coated in color. Accordingly, the color tone of summer wood parts 3 (annual ring lines) can be freely controlled. Since the soft spring wood parts 2 is coated with thermosetting resin 4, the strength and hardness of the surface is enhanced and consequently the scratch resistance and the like of decorative material is improved. Further, by grinding the surface through sanding, cracks are prevented from developing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a decorative material used for wood flooring and the like.

[Conventional technology]

Traditionally, decorative materials such as flooring materials are made by vacuum impregnating a wooden veneer with polyester resin and curing it by heating and pressurizing it.
It had improved properties such as hardness, mechanical strength, and heat resistance.

On the other hand, another known method is to overcoat the surface of a wooden veneer with a resin and then cure the resin. In addition to polyester resin, acrylic resin,
Phenol resin etc. were used.

[Problem to be solved by the invention]

In the case of vacuum impregnation with resin, a vacuum pot is required and production is performed in batches, which has the drawbacks of low production efficiency and large-scale equipment.

Additionally, the overcoat method has the disadvantage that surface unevenness tends to occur due to differences in the permeability of the resin to various types of veneers.

Furthermore, the decorative materials obtained by these methods have a problem in that the woody texture disappears due to resin treatment.

Therefore, an object of the present invention is to provide a decorative material that has a high production efficiency, can be uniformly treated with resin without requiring large-scale equipment, and has a woody feel.

[Means to solve the problem]

The decorative material of the present invention is obtained by applying a thermosetting resin to the surface of a wooden material, curing it by heating, sanding the surface, and then painting the surface.

The decorative material of the present invention also includes a base plate, and a wooden veneer that is adhered to the surface of the base plate, coats a thermosetting resin on the surface, heats and hardens the surface, sands the surface, and then paints the surface. It also includes those with

[Effect]

According to this invention, since a thermosetting resin is applied to a wooden material or a wooden veneer and cured, continuous production is possible and large-scale equipment such as a vacuum pot is not required.

By sanding the surface of a hardened thermosetting resin, the surface is ground and the resin becomes uneven on the surface due to the difference in permeability of the resin, giving it a woody feel.

[Example] An example of the present invention will be described based on FIG. 1st
The figure shows the process of manufacturing this decorative material.
The surface of the material (solid softwood, veneer, laminated wood, etc.) is floated or sandblasted, and the soft spring material 2 is ground (see (A) and (B) in the same figure). The summer wood part 3 (annual ring line) remains and the surface becomes uneven. Next, a thermosetting resin 4 such as urethane resin or polyester resin is applied to the surface and the resin 4 is filled into the recess (FIG. 4(C)).
Then, the resin 4 is cured by heating and applying pressure if necessary ((D) in the same figure). After curing, the entire surface is sanded to grind the surface ((E) in the same figure), and colored coating is applied.

Therefore, the color tone of the summer wood portion 3 (annual ring line) can be freely controlled by the degree of sanding. Further, since the thermosetting resin 4 is applied to the soft spring material portion 2, the surface strength and hardness are increased, and scratch resistance and the like are improved. Furthermore, surface grinding by sanding separates the resins 4 from each other (see (E) in the same figure), thereby preventing the occurrence of cranks.

In addition, as shown in Fig. 2, a wooden veneer 6 (for example) is laminated and adhered to the surface of the base plate 5 (for example, a base plate), and then a colored thermosetting resin is applied and hardened by pressing. After sanding, the base plate 5 may be colored or painted.The base plate 5 used is one that has been subjected to resin impregnation treatment (WPC treatment).

In this case as well, in addition to the above-mentioned advantages such as preventing cranking and improving surface strength and hardness, it also improves water resistance and heat resistance, and also makes it possible to control annual ring color and base color.

Next, a method for manufacturing the decorative material shown in FIG. 2 will be explained based on FIG. 3. First, the veneer 6 and the base plate 5 are attached at an angle of 120 degrees using an adhesive (water-based vinyl urethane resetting adhesive SB, etc.).
C. Press at 8 kg/cd for 80 seconds to bond. Next, polyester resin is applied to the surface of the veneer 6, and
It is hardened by pressing at 8 kg/c+j for 3 minutes at °C, and then seasoned for 1 day and night to reduce the moisture content to 4% or less. Furthermore, the surface of the veneer 6 is sanded. For sanding - #60, #120, #150. ．． #18
0 etc. can be used. Painting is done using urethane resin.
Apply the undercoat, intermediate coat, and topcoat in that order.

FIGS. 4(A) to 4(D) show a method of manufacturing a decorative material that allows free color patterns to be easily applied to the decorative material. Same figure (
In A), the decorative material is colored by coloring the base prior to overcoating with a thermosetting resin. The same figure (B
), coloring is performed after sanding, the same figure (C
) is overcoated with colored resin and colored.

In the same figure (CD), color painting is done in the final process.

When these methods are used, there is no need to prepare a large number of colored resins and color the decorative material as in the past, and the process is simplified.

[Effects of the Invention] According to the present invention, since the thermosetting resin is applied and cured, continuous production is possible and large-scale equipment such as a vacuum pot is not required.

By sanding the surface of the hardened thermosetting resin, the surface is ground, eliminating differences in the permeability of the resin, eliminating unevenness of the resin on the surface, and creating a woody feel.
