Description
【０００１】
【発明の属する技術分野】
本発明は、家具の部材や建材として用いられる人造大理石の組成物に関するものである。
【０００２】
【従来の技術】
従来から、合成樹脂と充填剤と柄を表現する柄材、硬化剤などの添加物を配合した人造大理石の樹脂組成物を所望の形状の金型に注型し、加熱してこの注型物を硬化させてることにより人造大理石を形成することが知られている。
【０００３】
人造大理石を製造するための原料となる合成樹脂としては、従来よりポリエステル系、アクリル系、ビニルエステル系などが用いられ、これらの充填剤として、水酸化アルミニウム、炭酸カルシウム、シリカ、ガラスパウダーなどが用いられ、更に、人造大理石の柄を表現する各種柄材が用いられている。
【０００４】
柄材は、その表現により添加量が増えると特に耐衝撃強度が低下して製品強度の低下を招くため、多量の添加ができないのが現状であった。
【０００５】
また、柄材の分布が人造大理石の厚み方向に不均一であるため、柄表現が不均一・斑模様になることが多かった。また、柄材の形状として球状のもののみを用いると、人造大理
石の表面側から見た場合、その球の表面部に一番近い部分だけが強調され、クッキリ感がなく全体がぼけた感じになるという問題があり、一方、柄材として扁平状のもののみを用いた場合、全体がクッキリ感で強調され、ぼけた感じがなくなってしまうという問題があった。
【０００６】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、人造大理石の柄表現を奥行き感、深み感、立体感のある表現とすることができると共に、柄材の分布を均一にして外観性に優れたものとすることができる人造大理石の組成物を提供することを課題とし、また、クッキリ感とぼけた感じを同一化して柄表現をより奥行き感、深み感、立体感のある表現とすることができる人造大理石の組成物を提供することを課題とするものである。
【０００７】
【課題を解決するための手段】
上記課題を解決するために本発明に係る人造大理石の組成物は、合成樹脂に充填剤と柄を表現する柄材、硬化材などの添加物を配合して得られる人造大理石の組成物において、複数種類の比重の異なる柄材を混合し、該混合する複数種類の比重の異なる柄材が球状をした柄材と偏平状をした柄材であり、この比重の異なる球状をした柄材と偏平状をした柄材がいずれも上記人造大理石の組成物に用いる合成樹脂、充填剤と同じ合成樹脂、充填剤で構成され、且つ、合成樹脂と充填剤との配合比を変えると共に異なる着色剤を添加して着色した樹脂組成物の硬化物を粉砕して得られたものであることを特徴とするものである。このような構成の人造大理石の組成物を用いて人造大理石を製造することで、形成される人造大理石の厚み方向に比重の異なる柄材が比重差により厚み方向に分布し、奥行き感、深み感、立体感のある人造大理石を得ることができ、また、球状をした柄材によるぼけた感じと、扁平状をした柄材によるクッキリ感とを併せもった奥行き感、深み感、立体感のある人造大理石を得ることができるものである。
【０００８】
そして、充填剤の粒径を３〜５０μとすることが好ましい。これにより人造大理石の組成物における分散性が向上し、また、得られる人造大理石の耐衝撃性が向上するものである。
【０００９】
また、充填剤として水酸化アルミニウムを用い、水酸化アルミニウムの配合量を樹脂１００重量部に対して１５０〜３００重量部とするのが好ましく、これにより得られる人造大理石の耐衝撃性能が低下しないようにできるものである。
【００１０】
【発明の実施の形態】
以下、本発明を実施形態に基づいて説明する。
【００１１】
本発明の人造大理石の組成物に使用する合成樹脂としては、アクリル樹脂、ポリエステル樹脂、ビニルエステル樹脂など通常の注型法で使用される合成樹脂を用いるが、使用する合成樹脂としては特に限定されるものではない。
【００１２】
また、充填剤としては、水酸化アルミニウム、シリカ、炭酸カルシウムなど通常の注型法で使用されるものが用いるが、使用する充填剤としては特に限定はない。
【００１３】
以下に述べる実施の形態においては合成樹脂としてビニルエステル樹脂を用い、充填剤として水酸化アルミニウムを用いた配合系を例に説明する。
【００１４】
ビニルエステル樹脂はビスフェノールＡ型やノボラック型などのものを用いるが特に限定されるものではない。このビニルエステル樹脂に充填剤として水酸化アルミニウムを配合する。
【００１５】
水酸化アルミニウムは、人造大理石の衝撃強度安定性の面からあらかじめ各種シランカップリング剤で処理されたものを用いることが好ましく。また，配合量が多くなると耐衝撃性能が低下してくる傾向となるため、樹脂１００重量部に対して１５０〜３００重量部が好ましい。
【００１６】
また、充填剤の粒径は人造大理石の組成物における分散性と得られる耐衝撃性の両面から３〜５０μのものが好ましい。
【００１７】
本発明に使用する柄材は、上記合成樹脂と充填剤（実施形態ではビニルエステル樹脂と水酸化アルミニウム）とで構成され、更に、各種の着色剤を添加して着色した樹脂組成物に硬化剤を適宜添加して加熱して硬化物を得て、この硬化物を目的とする粒径に粉砕する
ことで形成したものであり、合成樹脂と充填剤との配合比を変えることで、柄材の比重の異なるものを形成する。また、この比重差をつけた柄材としては、球状と扁平形状のもの を形成する。
ここで、上記のように合成樹脂と水酸化アルミニウムとの配合比で決まってくる柄材を得るための樹脂組成物は、人造大理石の樹脂組成物の比重と等しいかより大きいものとする。また、各色、あるいは柄材の大きさ（粒径）によっても、複数種類の比重の異なる柄材を設計製造して得ることができるものである。
【００１８】
このようにして調製された比重の異なる球状の柄材と扁平形状の柄材を目的とする柄表現に合うように適宜量添加配合する。
【００１９】
ここで、注型用の金型は上型と下型とから構成され、下型面が製品の表面側になるように設計されている。すなわち、人造大理石の組成物が金型内に注入されて満たされた時、その後加熱されて組成物が硬化する過程において、本発明の柄材は人造大理石の製品の厚み方向に、その比重差により分布が生じ、比重差の大きい程（比重が大きくなる程）沈降して金型の下面、すなわち製品表面側に集まる形になる。
【００２０】
したがって、従来の比重差をつけない柄材の構成に比べ、柄材が製品表面側に集まる構成となり、柄材の添加量が概ね１／２以下の量でも同様の柄を表現することが可能となり、また、従来のものよりも、柄材が少量で柄表現ができるから、その添加によって製品強度が極端に低下するようなことがないものである。また、柄材の色別や粒の大きさに比重差をつけることにより、沈降速度が異なるようにすれば、厚み方向にそれらの分布が生じて、更に複雑で立体感のある柄を表現することができるものである。
【００２１】
更に、上記比重差をつけた複数の柄材の形状が、球状と扁平形状であるのでこの２種類を混合・配合して注入した組成物は製品の厚み方向の表面側に立体的に分布を持ち、且つ、球状の柄材によるぼけた感じと、扁平な柄材によるクッキリ感が同時に表現され、全体的に透明感や深み感、奥行き感、立体感に優れた人造大理石を得ることができるものである。
【００２２】
人造大理石を製造するに当たっては、ビニルエステル樹脂及び充填剤に本発明の柄材を配合し、更に、硬化剤、及び各種添加剤を所定の割合で配合し、撹拌機等により混合撹拌して人造大理石の組成物を調製するものである。
【００２３】
このようにして得られる人造大理石の組成物を３〜５０Ｔｏｒｒ程度の減圧下で真空脱泡処理をし、脱泡され得られた人造大理石の組成物を所定の形状をした金型内に注入し、５０〜１１０℃の温度で３０〜１２０分間加熱する。ここで、加熱することで人造大理石の組成物中のビニルエステル樹脂とスチレンモノマー等の重合性モノマーが共重合反応を進行させて人造大理石の組成物の硬化成形を行うことができるものである。
【００２４】
このようにして得られた本発明の組成物を用いて成形した人造大理石は、人造大理石の柄表現をクッキリ感とぼけ感を同一化して非常に奥行きのある表現とすると共に、柄材の分布を均一化して外観性（透明感や深み感、奥行き感、立体感など）の優れた人造大理石を得ることができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a composition of artificial marble used as a furniture member or building material.
[0002]
[Prior art]
Conventionally, an artificial marble resin composition containing additives such as a pattern material expressing a pattern, a synthetic resin, a filler, and a curing agent is poured into a mold having a desired shape, and this cast is heated. It is known that an artificial marble is formed by curing.
[0003]
As synthetic resins that are used as raw materials for producing artificial marble, polyester-based, acrylic-based, vinyl-ester-based, etc. have been conventionally used, and these fillers include aluminum hydroxide, calcium carbonate, silica, glass powder, etc. In addition, various pattern materials that represent artificial marble patterns are used.
[0004]
In the present situation, the pattern material cannot be added in a large amount because the impact strength is lowered and the product strength is lowered particularly when the added amount is increased by the expression.
[0005]
In addition, since the distribution of the pattern material is not uniform in the thickness direction of the artificial marble, the pattern expression is often non-uniform and spotted. In addition, when only the spherical shape is used as the pattern material, when viewed from the surface side of the artificial marble, only the part closest to the surface part of the sphere is emphasized, and there is no clear feeling and the whole is blurred. On the other hand, when only a flat material is used as the pattern material, there is a problem that the whole is emphasized with a clear feeling and the blurred feeling disappears.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the pattern expression of the artificial marble can be expressed with a sense of depth, depth, and three-dimensionality, and the distribution of the pattern material is made uniform to improve the appearance. The objective is to provide an artificial marble composition that can be made excellent, and to make the pattern expression more depth, depth, and three-dimensionality by unifying the clear and blurred feeling. It is an object of the present invention to provide a composition of artificial marble that can be processed.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the composition of artificial marble according to the present invention is a composition of artificial marble obtained by blending additives such as a pattern material expressing a filler and a pattern with a synthetic resin, a curing material, A plurality of types of pattern materials having different specific gravities are mixed , and the plurality of types of pattern materials having different specific gravities to be mixed are a pattern material having a spherical shape and a flat pattern material. Each of the shaped pattern materials is composed of the same synthetic resin and filler as the synthetic marble and filler used in the above-mentioned artificial marble composition, and the blending ratio of the synthetic resin and the filler is changed and different colorants are used. It is obtained by pulverizing a cured product of a resin composition added and colored . By producing artificial marble using the composition of artificial marble having such a structure, the pattern material having different specific gravity in the thickness direction of the formed artificial marble is distributed in the thickness direction due to the difference in specific gravity, resulting in a sense of depth and depth. It is possible to obtain an artificial marble with a three-dimensional feeling , and also has a sense of depth, depth, and three-dimensionality that combines a blurry feeling with a spherical pattern material and a clear feeling with a flat pattern material. An artificial marble can be obtained.
[0008]
And it is preferable that the particle size of a filler shall be 3-50 micrometers. Thereby, the dispersibility in the composition of the artificial marble is improved, and the impact resistance of the resulting artificial marble is improved.
[0009]
In addition, it is preferable to use aluminum hydroxide as a filler, and the blending amount of aluminum hydroxide is preferably 150 to 300 parts by weight with respect to 100 parts by weight of the resin, so that the impact resistance performance of the resulting artificial marble is not lowered. It can be made.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments.
[0011]
As the synthetic resin used in the composition of the artificial marble of the present invention, a synthetic resin used in a normal casting method such as an acrylic resin, a polyester resin, or a vinyl ester resin is used, but the synthetic resin to be used is particularly limited. It is not something.
[0012]
Moreover, as a filler, what is used by normal casting methods, such as aluminum hydroxide, a silica, and calcium carbonate, is used, but there is no limitation in particular as a filler to be used.
[0013]
In the embodiment described below, a compound system using a vinyl ester resin as a synthetic resin and aluminum hydroxide as a filler will be described as an example.
[0014]
Vinyl ester resins such as bisphenol A type and novolac type are used but are not particularly limited. Aluminum hydroxide is blended in the vinyl ester resin as a filler.
[0015]
It is preferable to use aluminum hydroxide that has been treated with various silane coupling agents in advance from the viewpoint of impact strength stability of the artificial marble. Further, since the impact resistance performance tends to decrease as the blending amount increases, 150 to 300 parts by weight is preferable with respect to 100 parts by weight of the resin.
[0016]
The particle size of the filler is preferably 3 to 50 μm from the viewpoint of dispersibility in the artificial marble composition and the obtained impact resistance.
[0017]
The pattern material used in the present invention is composed of the above synthetic resin and filler (in the embodiment, vinyl ester resin and aluminum hydroxide), and further, a curing agent added to the resin composition colored by adding various colorants. Is formed by appropriately adding and heating to obtain a cured product, and pulverizing the cured product to a target particle size. By changing the blending ratio of the synthetic resin and the filler, the pattern material Of different specific gravity . Further, as the pattern material with the specific gravity difference, a spherical material and a flat material are formed.
Here, the resin composition for obtaining the pattern material determined by the blending ratio of the synthetic resin and aluminum hydroxide as described above is equal to or greater than the specific gravity of the artificial marble resin composition. Also, a plurality of types of pattern materials having different specific gravities can be designed and manufactured depending on each color or the size (particle size) of the pattern material.
[0018]
The spherical pattern material and the flat pattern material having different specific gravities prepared as described above are appropriately added and blended so as to match the intended pattern expression.
[0019]
Here, the casting mold is composed of an upper mold and a lower mold, and the lower mold surface is designed to be the surface side of the product. That is, when the artificial marble composition is injected into the mold and filled, the pattern material of the present invention has a difference in specific gravity in the thickness direction of the artificial marble product in the process of heating and then curing the composition. As a result, the larger the difference in specific gravity (the greater the specific gravity), the more settled and gathered on the lower surface of the mold, that is, on the product surface side.
[0020]
Therefore, compared to the conventional pattern material configuration that does not give a specific gravity difference, the pattern material is gathered on the product surface side, and the same pattern can be expressed even if the amount of the pattern material added is approximately 1/2 or less. In addition, since the pattern can be expressed with a small amount of pattern material compared to the conventional one, the addition of the pattern material does not cause the product strength to be extremely lowered. In addition, if the sedimentation speeds are made different by giving specific gravity differences to the color of the pattern material and the size of the grains, their distribution occurs in the thickness direction to express a more complicated and three-dimensional pattern. It is something that can be done.
[0021]
Furthermore, since the shapes of the plurality of patterns having the specific gravity difference are spherical and flat, the composition injected by mixing and blending these two types has a three-dimensional distribution on the surface side in the thickness direction of the product. The artificial marble with excellent transparency, depth, depth, and three-dimensionality can be obtained as a result of having both the softness of the spherical pattern material and the clearness of the flat pattern material. Is.
[0022]
In producing artificial marble, the pattern material of the present invention is blended with the vinyl ester resin and the filler, and further, the curing agent and various additives are blended at a predetermined ratio, and mixed and stirred by a stirrer or the like. A marble composition is prepared.
[0023]
The artificial marble composition thus obtained is subjected to vacuum defoaming treatment under a reduced pressure of about 3 to 50 Torr, and the defoamed artificial marble composition is injected into a mold having a predetermined shape. And heating at a temperature of 50 to 110 ° C. for 30 to 120 minutes. Here, by heating, a vinyl ester resin in the composition of the artificial marble and a polymerizable monomer such as a styrene monomer cause a copolymerization reaction to proceed, whereby the artificial marble composition can be cured and molded.
[0024]
The artificial marble molded using the composition of the present invention thus obtained has a very deep expression by making the pattern expression of the artificial marble clear and blurred, and the distribution of the pattern material It is possible to obtain an artificial marble having a uniform appearance and excellent appearance (transparency, depth, depth, stereoscopic effect, etc.).
