Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a decorative material having a wood grain pattern.
To provide a decorative material with a wood grain pattern exhibiting a so-called 5-zukuri-like board grain state by polishing Japanese materials such as cedar, pine, and cypress to remove the soft parts of the spring wood and leaving the hard parts of each village. It is something.

[Conventional technology]

Decorative materials with wood grains include: [1] Printing a wood grain pattern with pearl ink to express the shine of natural wood; (H) After printing a wood grain pattern on a base material for decorative materials that has been subjected to surface treatment. This entire surface is coated with two coats of matte paint, and then the entire surface is printed with glossy paint in the shape of wood grain that matches the wood grain pattern to bring out the shine of natural wood (%
Publication No. 52-4603), [iii) After printing a wood grain pattern on the base material for decorative materials, the winter wood part-1- of this wood grain pattern is printed with a build-up of PVC sol ink, and if necessary, By forming a matte layer with mud ink on the spring wood part of the wood grain pattern, a decorative wood grain material with an undulating pattern (% 1986-5786, 1987-5787, JP 56-5787, Publication No. 56-5788)
etc. exist.

[Problem that the invention seeks to solve]

By the way, in each of the above decorative materials, [I] and [11]
The decorative materials described in 2. not only do not have a tactile three-dimensional effect, but also lack a visual three-dimensional effect because the glazed parts aiming for a three-dimensional effect are formed flat, and the wood grain pattern of natural wood is not good. There are disadvantages in that there is a large difference in the feel of the decorative material, and the three-dimensional effect of the surface of the decorative material is likely to be diminished due to unevenness on the surface of the plywood used as the decorative base material.

In addition, Me (IN
Note that the decorative material in item ) includes a step in the manufacturing process that uses PVC sol ink, and the drying properties in this step are poor, and a step is required to gel the PVC sol ink. Therefore, the manufacturing process is complicated, and the build-up formed on the wood-grained winter wood portion is unnatural, and the transparency is also unnatural.

However, Japanese materials such as cedar, pine, and cypress are polished to remove the soft parts of the spring wood, and the hard parts of each village are left behind to create a decorative material that exhibits a so-called 5-zukushi style, that is, winter wood. There is no wood-grained decorative material that faithfully reproduces the two conditions: the parts are protruding and have a glossy surface, and the shaved spring wood parts are concave and matte. is the current situation.

[Means for solving problems]

The 5-zukushi style wood grain decorative material of the present invention comprises a base material for a decorative material having a printed pattern layer with a wood grain pattern of a winter wood part and a spring wood part on the surface, and a winter wood part in the printed wood grain pattern layer. A winter wood part fill-up printing part made of a thermosetting synthetic resin layer formed by a gravure printing means in direct contact with the printed pattern layer, and a spring part in the printed pattern layer of the wood grain pattern. The spring material part is provided with a spring material part printed part made of a matte-like synthetic resin layer formed on the region of the material part so as to be in direct contact with the printed pattern layer, and furthermore, the material part is made of the thermosetting synthetic resin. The surface of the winter material part overlay printed part made of a layer is formed to protrude more than the surface of the spring material part printed part made of a synthetic resin layer which also exhibits a matte tone.

In the 5-zuku Q tone wood grain decorative material of the present invention having the above structure, the base material for the decorative material is a general sheet-like material used as this type of base material, for example, a basis weight of 23 to 3007.
In addition to paper sheets and Parzoboard, sheets made of resin such as polyethylene, polypropylene, and polyester,
Various types of wood and plywood are used.

The printed pattern layer of the wood grain pattern on the surface of the base material for decorative materials is
Usually, vinyl chloride-vinyl acetate copolymer, nitrocellulose, etc. are coated with a binder ink or paint, for example, by roll coating.

It is generally formed through a base coat layer formed by coating with a common coating method such as gravure coating, bar code coating, or air knife coating.

A printed pattern layer with a wood grain pattern is produced, for example, by adding a dye, a coloring agent such as Kao I'-1, or a pearl pigment or metal powder pigment to a vehicle made of vinyl chloride-vinyl acetate copolymer or nitrocellulose. 1 - Add additives such as plasticizers, stabilizers, waxes, greases, desiccants, auxiliary desiccants, curing agents, thickeners, 2 dispersants, fillers, etc. as necessary, and add solvents and diluents. It is formed by printing a wood grain pattern consisting of a winter wood part and a spring wood part using general printing methods such as gravure, offset, and offset gravure, using all the ink or paint that has been sufficiently kneaded with It is something.

On the area of the winter wood part in the printed pattern layer of the wood grain pattern,
The overlay printed portion of the winter material part, which is formed so as to be in direct contact with the printed pattern layer, is formed by gravure printing means using ink or paint using a thermosetting synthetic resin as a vehicle. For example, polyol components such as polyvinyl chloride polyol, acrylic polyol, polyester polyol, polyether polyol, cellulose polyol, and polyols made of derivatives thereof, and tolylene diisocyanate-1, methylene diisocyanate-1, and xylene diisonanate. .

An acid catalyst such as para-toluenesulfonic acid is completely added to an alkyd resin component such as urethane resin or glyptal resin, which is an addition product with an isocyanate component such as hexamethylene diisocyanate, and an amine resin component such as urea resin or melamine resin. A two-component curing type resin such as an epoxy resin consisting of an acid-cured amino alkyd resin, an epoxy resin component, and a polyamine component such as polyamide, ethylenediamine, diethylene triamine, or a polybasic acid such as phthalic anhydride; Alternatively, extender pigments used mainly to increase the solid component ratio of inks and paints, such as bary l-, precipitated barylum sulfate, chalk, and precipitated calcium carbonate, are added to vehicles such as resins made from block polymers. , white plaster, alumina white, clay, talcum powder, heptium silicate, precipitated magnesium carbonate, gloss white, sachin white, bentonite, etc.
If necessary, add a gloss control agent or anti-blocking agent such as micro silica or Teflon powder made by calcining precipitated silica, and further add a coloring agent made of any dye or pigment, a bright coloring agent, and a solvent/diluent. , for example, esters such as methyl acetate, ethyl acetate, butyl acetate, toluene,
Inks or paints are used that are thoroughly kneaded with various solvents such as aromatic solvents such as xylene, alcoholic solvents such as methanol, ethanol, and isozorobyl alcohol, and ketone solvents such as methyl ethyl ketone, methyl isobutyl ketone, and cyclohexanone. . In the ink or paint, when an inorganic opaque pigment is used as a coloring agent, it is preferable that the amount of the pigment be 5 or less so that the proportion of the total component is 2 or less. Even when using it, it is preferable to keep it below 10 parts.
By blending the coloring agent, the printed portion of the winter wood part is adjusted to have both transparency and surface gloss, and to exhibit the so-called amber color that the winter wood part of natural wood embodies.

The glittering color former, which can be added as desired, is a pearl pigment with a particle size of about 5 to 60 microns made by coating the surface of finely powdered mica with titanium oxide or iron oxide and making it into flakes or scales, or a bronze pigment. Metal powder pigments made of metal powder, such as powder, aluminum powder, copper powder, etc., are used, but it is preferable that this bright coloring agent is also kept at 10q6 or less in the total components of the ink or paint.

In addition, typical composition ratios of the ink or paint for forming the above-mentioned winter wood part overlay printing part are as follows: (1) Extender pigment: 1σ to 50 parts by weight (2)
Coloring agent: 0 to 15 parts by weight (3
) Glitter coloring agent: 0 to 15 parts by weight (4) Solvent:
・・・・・・・For urethane-based vehicles, 15-35 parts by weight of a polyol component and 5-35 parts by weight of an incyanate component are added to 20-50 parts by weight, and for aminoalkyd-based vehicles. In the case of an epoxy vehicle, 30 to 60 parts by weight of the vehicle may be added, and in the case of an epoxy vehicle, 30 to 50 parts by weight of the vehicle may be added.

The winter material part overlay printing part is usually built up to a thickness of about 10 to 150μ, and is used as a winter material part overlay printing part that realizes gradation by gravure multi-stage printing means. This creates a wood grain pattern that more closely resembles natural wood. This winter material part overlay printing part is usually formed by a gravure printing method, for example, the number of screen lines is 2.
0 l/in ch ~10013/in
It is preferable that the printing plate be formed by gravure printing using a plate with a high corrosion depth obtained by further etching a plate made using a screen such as a Munsen screen, a grain screen, a spiral screen, a parallel screen, etc. If the corrosion depth of the gravure printing plate is less than 100μ, the build-up effect of the printed overlay of the winter material part will be insufficient, while if the corrosion depth exceeds 300μ, the winter material part will be sufficiently sharp. Since it is difficult to obtain a built-up printed area, it is optimal to form the plate using a gravure printing plate with a corrosion depth of about 100 to 300 μm.

Generally, when a deep plate is obtained by etching, there is a close relationship between the shape of the corrosion cells of the obtained plate, the printability and the build-up effect obtained. In other words, if the ratio of the cell width to the bank width in a corroded cell of a printing plate is 8=1 or more, the pattern obtained with this printing plate will lack sharpness, and the ratio of the cell width to the bank width will be less than 1. If the ratio is less than 1:1, the resulting pattern will have a poor build-up feel, so the ratio of the cell opening to the bank width should be 1:1.
It is preferable to use a ratio within the range of =1 to 8:1. Furthermore, in the corrosion cells of the printing plate, if the ratio of the cell width to the depth is 5:1 or more, the ink transferability during the printing process is good, but the transferred ink tends to flow; Ratio of cell frontage to depth is 1=
If it is less than 1, the ink transferability is likely to be poor during the printing process, so the ratio of the cell opening to the depth should be 1:1 to 65.
:1 is preferably used.

In the area of the spring wood part in the printed pattern layer of the wood grain pattern mentioned above,
The spring material part printed part, which is formed to be in direct contact with the printed pattern layer, is made of a binder component made of vinyl chloride-vinyl acetate copolymer or a thermosetting resin such as polyurethane resin. , extender pigments such as Micronrica for matting, coloring pigments added as necessary, plasticizers, slip agents, waxes, greases, drying agents,
It is made of ink or paint that has been sufficiently kneaded with the addition of thickeners, dispersants, solvents, diluents, etc., and the overlay printing of the winter wood part is higher than the surface of the spring wood part printed part. It is constructed so that the surface of the part is convex.
