Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a novel polyvinyl chloride decorative board, more specifically, it has a three-dimensional effect, a deep pearl-colored appearance, and a texture similar to paper, and has good design properties. The present invention relates to a polyvinyl chloride decorative board which has excellent paint surface properties and water resistance, and is suitable as a decorative board for floor coverings, kitchen materials, furniture materials, etc.

Conventional technology Conventionally, polyvinyl chloride decorative boards have been used, for example, those that are simply printed on the surface, those that have pigments kneaded into them, those that are coated on the base side, those that are laminated with a plastic film, or those that are coated on the bare side, or those that have a plastic film laminated on the surface. Matte finishing, embossed finishing, and combinations thereof are known.

However, such conventional polyvinyl chloride decorative laminates do not necessarily have sufficient design properties, and are not allowed to be used, for example, in kitchen materials or furniture materials that require a high-class look. There are drawbacks. In particular, the fact is that a polyvinyl chloride decorative board that is soft, has a pearly feel, has a three-dimensional effect, and has a deep color tone has not yet been found.

On the other hand, many paper decorative boards are integrated with resin, and some are known that have pearl printing and colored printing layered on the same paper surface, but paper with watermarks is also known. Those with a structure that gives a three-dimensional effect, such as the pearl printing layer or colored layer being visible through the paper, and those with improved water resistance without sacrificing the three-dimensional effect or matte feel of the paper,
It has not been found so far.

Problems to be Solved by the Invention Under these circumstances, the present invention has an excellent design, such as a three-dimensional appearance, a deep pearl-colored appearance, and the texture of paper, and also has excellent paint surface properties and water resistance. The purpose of this invention is to provide a polyvinyl chloride decorative board that has good properties and is suitable for use as kitchen materials, furniture materials, etc. that require a high-class feel.

Means for Solving the Problems As a result of intensive research to develop a polyvinyl chloride decorative board having the above-mentioned favorable properties, the present inventors have developed a transparent flexible polyvinyl chloride sheet (surface layer) and a paper with markings. (middle layer) and a colored soft polyvinyl chloride sheet (bottom layer) with a pearl pigment-containing coating layer on the surface. layer) and a transparent flexible polyvinyl chloride sheet containing a pearl pigment, or a transparent flexible polyvinyl chloride sheet having a coating layer containing a pearl pigment on its surface (middle layer), and a colored flexible polyvinyl chloride sheet (bottom layer). It was discovered that the purpose could be achieved by using a structural decorative board, and the present invention was completed based on this knowledge.

That is, in the present invention, (A) a colored flexible polyvinyl chloride sheet having a pearl pigment-containing coating layer on the surface is the lowermost layer, and (B) polyvinyl chloride fibers of 1 to 50 % by weight, acrylic fiber, rayon, and polyvinyl alcohol with a basis weight of 5 to 30 g/+*' and (C) a transparent flexible polyvinyl chloride sheet with a thickness of 0.03 to 2.0+u+ are laminated in sequence. The bottom layer is a polyvinyl chloride decorative board with a three-layer structure and (a) a colored soft polyvinyl chloride sheet, and on top of this sheet, (
b) A transparent flexible polyvinyl chloride sheet containing a pearl pigment or a transparent flexible polyvinyl chloride sheet having a coating layer containing a pearl pigment on the surface side, (C) 1 to 50% by weight of polyvinyl chloride fiber, acrylic fiber, and rayon. and polyvinyl alcohol, and (d) polyvinyl chloride consisting of a 4-layer structure in which transparent soft polyvinyl chloride sheets with a thickness of 03 to 2.0 m+m are sequentially laminated. The present invention provides decorative boards based on the above-mentioned products.

The present invention will be explained in detail below.

In the decorative laminate of the present invention, there is no particular restriction on the polyvinyl chloride resin used for the transparent flexible polyvinyl chloride sheet or the colored flexible polyvinyl chloride sheet, and any polyvinyl chloride resin that is used conventionally for polyvinyl chloride decorative laminates may be used. It can be used selectively.

These flexible polyvinyl chloride sheets usually contain a plasticizer component in an amount of 2 to 50% by weight. The plasticizer component consists of a plasticizer, a heat stabilizer, and a lubricant, and examples of the plasticizer include heptalic acid esters such as dioctyl phthalate, dibutyl phthalate, and butylbenzyl phthalate, dioctyl adipate, and adipine. Aliphatic dibasic acid esters such as di-n-butyl acid and dibutyl sebacate, glycol esters such as pentaerythritol ester and diethylene glycol dibenzoate, phosphoric acid esters such as tricresyl phosphate and triphenyl phosphate, and epoxidation. Epoxidized oils such as soybean oil and epoxidized linseed oil, acetyl tributyl citrate, acetyl trioctyl citrate,
Examples include citric acid esters such as tri-n-butyl citrate, trialkyl trimellitate, tetra-n-octyl pyromellitate, polypropylene adipate, and other polyester plasticizers, and each of these may be used alone. However, two or more types may be used in combination.

Examples of heat stabilizers include metal soaps such as calcium stearate, zinc stearate, and lead stearate, and organic tin compounds such as tribasic zinc sulfate, dibasic zinc phosphite, and dibutyltin laurate. Each of these may be used alone or in combination of two or more.

Furthermore, as lubricants, stearic acid, valmitic acid,
These include fatty acid lubricants such as myristic acid, fatty acid amide lubricants such as stearic acid amide, palmitic acid amide, and methylene bisstearamide, ester lubricants such as butyl stearate, polyethylene wax, and liquid paraffin. One type may be used, or two or more types may be used in combination.

Pearl pigments used in the decorative board of the present invention include:
Examples include natural mica, fish scale powder, metals such as bismuth, lead, and their compounds, and those coated with mica or titanium oxide. Of these, mica coated with titanium oxide has a high resistance to impurity. It is suitable because it provides a paper-like texture to the decorative board. Natural mica usually has a weight average particle diameter of 10 to 100 μm and a weight average thickness of 0.5
Those having a shoulder diameter of ~20μ, an average aspect ratio of 10 to 100, and a bulk specific gravity of 0.1 to 0.8 are used.

One type of the pearl pigment may be used, or two or more types may be used in combination.

In the decorative board of the present invention, there are no particular restrictions on the colorant used in the colored flexible polyvinyl chloride sheet, and any colorant can be selected from those conventionally used for coloring plastics. Such coloring agents include, for example, metals such as aluminum powder and bronze powder, carbons such as carbon black, oxides such as titanium oxide, zinc white, and red iron, sulfates such as precipitated barium sulfate, and calcium carbonate. Inorganic pigments such as carbonates such as basic magnesium carbonate, silicates such as clay, chromates such as yellow lead, aluminates such as cobalt blue, ferrocyan compounds such as navy blue; toluidine red , Permanent Carmine FB, Disassoe Mouth-AAA.

Azo pigments such as Lake Red C, polycyclic pigments such as phthalocyanine blue, indanthrone blue, and quinacridone red, dyeing lakes such as Victoria Pure Blue BO lake and alkali blue toner, azine pigments, and fluorescent pigments. and dyes such as basic dyes, acid dyes, oil-soluble dyes, and disperse dyes. These colorants may be used alone or in combination of two or more.

The decorative board of the present invention has a three-layer structure or a four-layer structure, and the bottom layer of the three-layer decorative board is provided with a pearl pigment-containing coating layer as layer (A) on the surface side. A colored flexible polyvinyl chloride sheet is used as the lowermost layer (a) of a four-layer decorative board. These bottom layers are layers that have the function of coloring in appearance from the surface layer.

The colored polyvinyl chloride sheet may contain the colorant therein, or may have a colorant-containing coating layer provided on the surface side. When a colorant is included, the content is usually selected within the range of 5 to 20% by weight. If this amount is less than 5% by weight, the coloring density will be insufficient, and if it exceeds 20% by weight, if desired, when another sheet is attached to the back side of the sheet with an adhesive, the adhesion will be poor and undesirable. .

On the other hand, when providing a colorant-containing coating layer on the surface side of the polyvinyl chloride sheet, for example, the colorant is applied to an acrylic resin, a polyester resin, a vinyl chloride/vinyl acetate resin, a polyolefin resin, or a composite resin thereof. A coating layer with a thickness of about 0.5 to 10 μm is created using a paint containing 5 to 20% by weight based on the total weight of resin and colorant, diluted with a solvent such as alcohol, ester, or ketone. Let it form.

If the content of the cough coloring agent is less than 5% by weight, the coloring density will be insufficient, and if it exceeds 20% by weight, the adhesion of the coating film to the polyvinyl chloride sheet and the bonding strength of the coating film itself will tend to decrease. Be looked at. In addition, if the thickness of the film is less than 0.5μ, the coloring by the paint film is insufficient, and if it exceeds IOμ, the adhesion of the paint film to the polyvinyl chloride sheet and the bonding strength of the paint film itself decreases. There is a tendency to do this, which is not desirable.

The thickness of this colored flexible polyvinyl chloride sheet is usually 0.
05 to 0.2+ue, and the content of the plasticizer component is advantageously in the range of 2 to 30% by weight from the viewpoint of lamination workability. If the content of this plasticizer-based component is less than 2% by weight, plasticity will be insufficient and processability will be poor; if it exceeds 30% by weight, if desired, if another sheet is attached to the back side with an adhesive, etc. This is not preferable because it causes problems with adhesive strength and flatness.

When the decorative board of the present invention has a three-layer structure, the coating layer containing the Burl pigment is provided on the surface side of the colored flexible polyvinyl chloride sheet. In this case, preferably 5 to 25% by weight of the burl pigment is added to, for example, acrylic, polyester, vinyl chloride/vinyl acetate, polyolefin resin, or a composite resin thereof, based on the total weight of the resin and pearl pigment. The pearl pigment-containing coating layer is formed by coating the mixture using a coating material diluted with a solvent such as alcohol, ester, or ketone. The thickness of this coating layer is 0
．． A range of 5 to 10 μm is preferred. If the content of the pearl pigment is less than 5% by weight, the light scattering, reflection, and light interference effects of the pearl pigment will not be sufficient, and if it exceeds 25% by weight, the hiding power will increase and the underlying colored layer will not be utilized. can be seen.

On the other hand, when the decorative board of the present invention has a four-layer structure, on the colored flexible polyvinyl chloride sheet of the layer (a), the layer (b) is a transparent flexible polyvinyl chloride sheet containing a pearl pigment or the surface of the transparent flexible polyvinyl chloride sheet containing a pearl pigment. A transparent flexible polyvinyl chloride sheet provided with a pearl pigment-containing coating layer is laminated on the surface. In the transparent flexible polyvinyl chloride sheet containing the pearl pigment, the content of the pearl pigment is usually selected in the range of 10 to 20% by weight. If this amount is less than 10% by weight, the light scattering, reflection, and light interference effects of the pearl pigment will be insufficient, and the design of the paper will not be utilized, and if it exceeds 20% by weight, the hiding power will increase and the underlying colored layer will be damaged. There is a tendency for it to be less reflected when viewed from the surface. In addition, when using a sheet provided with a burl pigment coating layer on the surface side of the transparent flexible polyvinyl chloride sheet, the coating layer is the second lower layer (A) in the three-layer structure described above. It is set up in the same way as.

The content of pearl pigment in this coating layer is usually selected in the range of 5 to 25% by weight, and the thickness of the coating layer is 0.5 to 1% by weight.
It is desirable that it be in the range of 0/711. If the pearl pigment content in the coating layer is less than 5% by weight, the light scattering, reflection, and light interference effects of the pearl pigment will be insufficient and the design of the paper will not be utilized, and if it exceeds 25% by weight, the hiding power will be reduced. Furthermore, there is a tendency for the colored layer of the base to be less reflected when viewed from the surface layer.

Furthermore, the thickness of the polyvinyl chloride sheet of layer (b) is usually selected within the range of 0.05 to 0.2 mm, and the content of plasticizer components in the sheet is controlled to ensure lamination processability. From this point of view, it is usually selected in the range of 5 to 30% by weight. If the content of this plasticizer component is less than 5% by weight, the plasticity will be insufficient and lamination processability will be poor; if it exceeds 30% by weight, thermal deformation will occur during lamination processing, resulting in poor reflection of the pearl pigment and optical interference. There is a tendency for light scattering to decrease.

The transparent flexible polyvinyl chloride sheet of layer (b) may contain the above-mentioned coloring agent as long as the transparency is not lost, if desired, for the purpose of diversifying color tones.

When the decorative board of the present invention has a three-layer structure, the (B) layer is made of polyvinyl chloride as the layer (A), that is, on the side surface of the coating layer of the colored flexible polyvinyl chloride sheet whose surface is provided with a pearl pigment-containing coating layer. Watermarked paper made of vinyl chloride fibers, acrylic fibers, rayon, and polyvinyl alcohol is laminated.

On the other hand, in the case of a four-layer structure, layer (b) is formed on the transparent flexible polyvinyl chloride sheet containing a pearl pigment or the transparent flexible polyvinyl chloride sheet having a pearl pigment-containing coating layer on the surface side ( c) Watermarked paper made of polyvinyl chloride fibers, acrylic fibers, rayon, and polyvinyl alcohol is laminated as a layer.

In order for the watermarked paper to have the texture of paper and also the bonding strength as a laminate, the basis weight should be 5 to 3.
It is necessary that the amount is 0 g/II2, preferably in the range of 5 to 22 g/II2. If the basis weight is less than 59/ml, the lamination properties are good, but the texture as a paper is insufficient;
If it exceeds 0y/ra'', the texture as a paper will further increase, but the overlapping pattern of the base color and the burl color will become difficult to see, and the bonding strength as a laminate will tend to decrease.

In the Sukashijin paper, polyvinyl chloride fibers function best in terms of bonding strength when laminated with polyvinyl chloride sheets, but since they are transparent in appearance, they do not contribute much to the design. The content of this polyvinyl chloride fiber in paper making must be selected within the range of 1 to 50% by weight, preferably 5 to 20% by weight. If this content is less than 1% by weight, the paper will tend to peel off, and if it exceeds 50% by weight, the design of the paper will tend to deteriorate. Further, the acrylic fiber functions both in bonding strength with the polyvinyl chloride sheet and in terms of design, and its content is usually selected in the range of 1 to 80% by weight, preferably 40 to 70% by weight. This amount is 1% by weight
If it is less than 80%, the paper will have poor design, and if it exceeds 80%, the paper tends to peel easily.

Furthermore, rayon functions to improve the design and paper strength of paper making, and as its content increases, the design of the paper improves and the paper strength also increases, but the adhesive strength of the polyvinyl chloride sheet becomes weaker and the strength of the laminate increases. Bond strength decreases. The content of the rayon is
It is usually selected in the range of 1 to 50% by weight, preferably 5 to 20% by weight. Further, polyvinyl alcohol functions to improve paper strength in paper making, and its content is usually selected in the range of 1 to 30% by weight, preferably 5 to 15% by weight. This amount is 1% by weight
If it is less than 30% by weight, the strength of the paper will not be sufficient, and if it exceeds 30% by weight, the transparency of the paper will tend to increase and the design will be poor. This kind of water-resistant paper does not contain any pulp components, so it has excellent water resistance.

In the decorative board of the present invention, in the case of a three-layer structure, the above-mentioned (
CC' on top of the watermarked paper of layer B), or in the case of a four-layer structure, on top of the watermarked paper of layer (c).
Transparent flexible polyvinyl chloride sheets having a thickness of 0.03 to 2.01 m, preferably 0.2 to 1.0 m+m are laminated as the layer ) and the layer (a). The thickness of this sheet is 0.03+
If it is less than 2.01 m, it will be difficult to obtain a product with a homogeneous appearance due to the unevenness of the underlying papermaking layer during lamination processing.
There is not much difference in appearance even if it exceeds this.

The more mirror-like the transparent flexible polyvinyl chloride sheet, the better the design of the decorative board, but the surface may be embossed or matted if desired. Also,
If desired, a colorant may be added to the transparent flexible polyvinyl chloride sheet for the purpose of diversifying color tones within a range that does not impair the transparency of the colorant.

The content of the plasticizer component in this transparent flexible polyvinyl chloride sheet is appropriately selected depending on the use of the decorative board, and for example, when used for floor coverings, it is preferably in the range of 15 to 40% by weight. In addition, when used for furniture doors etc.
A range of 15% by weight is preferred. In other words, when used in applications that are subject to considerable loads, it is advantageous to make it flexible in order to have good impact resistance, while when used in furniture etc., dimensional stability and flatness are required. Therefore, something that is somewhat hard is advantageous.

There are no particular limitations on the method for producing the polyvinyl chloride decorative laminate of the present invention, and methods commonly used in the production of conventional glass laminated decorative laminates, such as thermocompression bonding, can be used.

In the decorative board of the present invention, in order to improve wear resistance, scratch resistance, stain resistance, etc., a protective layer made of another resin is optionally added to the surface of the uppermost transparent flexible polyvinyl chloride sheet. It may be provided. Preferred examples of the resin include acrylic resins, epoxy resins, polyester resins, silicone resins, and composite resins thereof. In addition, the thickness of the protective layer is usually 5 to 20 pl+
selected within the range. If the thickness is less than 5 μm, the function as a protective layer will not be fully demonstrated, and if it exceeds 20 PII, the protective layer will tend to crack or peel, and the decorative board will tend to curl. It will be done.

Next, the decorative laminate of the present invention will be explained according to the attached drawings. FIGS. 1, 2, and 3 are sectional views showing different examples of the decorative laminate of the present invention, and FIG. A three-layer structure is shown in which a watermarked paper 3 and a transparent soft polyvinyl chloride sheet 4 are laminated in sequence on a colored soft polyvinyl chloride sheet 1 on which a coating layer 2 containing a burl pigment is provided.
