【発明の属する技術分野】
本発明は、プレス成形による新規な抽象模様・外観・意匠を有する成形材料及び成形品、特に抽象模様を有するBMC成形材料に関するものである。
【0002】
【従来の技術】
周知のように、繊維強化熱硬化性樹脂(以下、FRPと略す)は、金属に比べ軽量で強度、耐蝕性に優れる等、多くの特徴を有しており、浴槽、浄化槽、等の住宅用部材、パイプ等の工業用部材、各種電気部品等、多岐に亘って使用されている。このようなFRPの成形方法には、多くの種類があるが、その一つにプレス成形法がある。この方法は、所定の温度に加熱された金型内にFRP材料を投入し、プレス機械で加圧・加熱硬化させる方法であり、FRP材料としては一般的にBMC、SMC等成形材料が用いられている。プレス成形法は、材料ロスが少ない、生産性が高い、作業環境が良い等、他のFRP成形法に比べ多くの長所を有し、FRP成形品の生産に広く用いられている。
【0003】
BMC、SMC成形材料は、このように多くの長所を有しているため、近年、バスタブ、洗面化粧台、台所カウンター等の人造大理石関係の用途にも広く利用されており、高級化、多様化のニーズに対応するため、色・柄等について様々な種類の製品が開発されている。例えば、特開平4−348155号公報では、アスペクト比1〜8の着色された繊維状物質を0.1〜4重量%混合するSMC成形材料が知られているが、このものは、砂岩模様の人造大理石である。
【0004】
こうした成形材料の色・柄としては、石目模様調の人造大理石が主流であり、その製法は、例えば石英、ガラス、大理石、雲母等の天然砕石、又は不飽和ポリエステル樹脂、アクリル樹脂等からなる人造粉砕物を添加配合して石目模様調人造大理石を得る方法が取られている。しかしながら、これらの方法で得られる石目模様調の人造大理石は、どれも似た外観であり、斬新性が乏しくなっている。
【0005】
一方、石目模様調以外の色・柄としては、筋状の流れ模様がある。その製法は、例えば、ベースコンパウンドに柄付け用カラーコンパウンドで流れ模様付けしたものを注型成形方法で流れ模様付き人造大理石とする方法である。
【0006】
しかしながら、注型成形では、一般的に流れ抽象模様を出し易いが、その反面、流れ筋の不自然な方向性や途切れ等の不具合が発生すれば、成形品として全く商品価値のない外観となり易いため、平板等の単純成形品であっても製造時には、細心の注意が必要で、更に、複雑な三次元形状品については形状的な制約があり、困難であった。こうした流れ抽象模様は、プレス成形法に至っては、尚更困難であり、未だ平板成形品での実用化も困難な状況にある。
【0007】
【発明が解決しようとする課題】
本発明の目的は、新規な斬新かつ高級感を有する抽象模様意匠の成形品が、平板形状はもとより複雑な三次元形状のものでも、プレス成形方法で簡単かつ安定的に成形できる成形材料、及び斬新な抽象模様を有する成形品にある。
【0008】
【課題を解決するための手段】
本発明者らは、新規意匠である独特の抽象模様を付与する方法について、鋭意研究した結果、本発明を完成するに至ったものである。
【0009】
即ち、本発明は、(A)熱硬化性樹脂、(B)重合性不飽和単量体、(C)繊維強化材、(D)着色有機繊維からなるラジカル硬化系成形材料をプレス成形法によって成形品を製造する方法であって、熱硬化性樹脂(A)が不飽和ポリエステル、ビニルエステル樹脂もしくはアクリル樹脂から選ばれるもので、着色有機繊維(D)が、平均繊維長0.1〜0.4mm未満で、アスペクト比15〜40のセルロース繊維であることを特徴とする抽象模様を有する成形品の製造方法を提供するものである。

【0014】
ジシクロペンタジエン系化合物とは、例えばジシクロペンタジエン、及びその誘導体が挙げられる。ジシクロ系不飽和ポリエステルは、ジシクロペンタジエンと無水マレイン酸に水を滴下反応して得られる反応生成物を更に多価アルコールとを反応して得る方法や、不飽和二塩基酸と多価アルコール類の反応生成物にジシクロペンタジンエンを反応する方法で製造される。
【0015】
本発明のエポキシアクリレート(II)とは、例えば、ビスフェノール・タイプのエポキシ樹脂の単独を、あるいは、ビスフェノール・タイプのエポキシ樹脂とノボラック・タイプのエポキシ樹脂との併用、1,6−ナフタレン型エポキシ樹脂のジ(メタ)アクリレート等になるものを指称し、その平均エポキシ当量が、好ましくは150〜450なる範囲内にあるようなエポキシ樹脂と、不飽和一塩基酸とを、エステル化触媒の存在下で、反応せしめて得られるものである。
【0016】
上記したビスフェノール・タイプのエポキシ樹脂としては、例えば、ビスフェノールA型エポキシ樹脂のジ(メタ)アクリレート、水添ビスフェノールA型エポキシ樹脂のジ(メタ)アクリレート、ビスフェノールAエチレンオキシド付加型エポキシ樹脂のジ(メタ)アクリレート、ビスフェノールAプロピレンオキシド付加型エポキシ樹脂のジ(メタ)アクリレート、ビスフェノールF型エポキシ樹脂のジ(メタ)アクリレート、1,6−ナフタレン型エポキシ樹脂のジ(メタ)アクリレート等を挙げることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a molding material and a molded article having a novel abstract pattern / appearance / design by press molding, and particularly to a BMC molding material having an abstract pattern.
[0002]
[Prior art]
As is well known, fiber reinforced thermosetting resin (hereinafter abbreviated as FRP) has many features such as light weight, strength and corrosion resistance compared to metal, and is used for housing such as bathtubs, septic tanks, etc. It is used in a wide variety of parts, industrial members such as pipes, various electric parts and the like. There are many types of such FRP molding methods, one of which is a press molding method. This method is a method in which an FRP material is put into a mold heated to a predetermined temperature, and is pressed and heated and cured by a press machine. As the FRP material, a molding material such as BMC or SMC is generally used. ing. The press molding method has many advantages over other FRP molding methods, such as low material loss, high productivity, and good working environment, and is widely used in the production of FRP molded products.
[0003]
BMC and SMC molding materials have many advantages, so in recent years they are widely used for artificial marble-related applications such as bathtubs, vanities and kitchen counters. Various types of products have been developed for colors and patterns to meet the needs of customers. For example, Japanese Patent Laid-Open No. 4-348155 discloses an SMC molding material in which 0.1 to 4% by weight of a colored fibrous substance having an aspect ratio of 1 to 8 is mixed. It is an artificial marble.
[0004]
As the color and pattern of these molding materials, stone-patterned artificial marble is the mainstream, and its manufacturing method is made of natural crushed stone such as quartz, glass, marble, mica, or unsaturated polyester resin, acrylic resin, etc. A method has been adopted in which artificial marble is added and blended to obtain a stone-patterned artificial marble. However, the stone-patterned artificial marble obtained by these methods all have a similar appearance and lack novelty.
[0005]
On the other hand, there is a streaky flow pattern as a color / pattern other than the stone pattern. The manufacturing method is, for example, a method in which a base compound is flow-patterned with a patterning color compound to form artificial marble with a flow pattern by a cast molding method.
[0006]
However, in cast molding, it is generally easy to produce a flow abstract pattern, but on the other hand, if there is a problem such as an unnatural direction or breakage of the flow line, it tends to have an appearance with no commercial value as a molded product. Therefore, even a simple molded product such as a flat plate requires careful attention during production, and a complicated three-dimensional shape product is difficult due to shape restrictions. Such a flow abstract pattern is still more difficult for the press molding method, and it is still difficult to put it into practical use in a flat plate molded product.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a molding material that can be easily and stably molded by a press molding method, even if a molded article of a novel novel and high-class abstract pattern design is not only a flat plate shape but also a complicated three-dimensional shape, and It is in a molded product with a novel abstract pattern.
