この発明はカウンタ等に使用する人造大理石の製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of manufacturing artificial marble used for counters and the like.
熱硬化性樹脂にガラス繊維その他の添加剤、充填材を加
えた成形材料を加熱下で圧縮成形する従来の人造大理石
の製造方法においては、成形材料中に着色材料を点在さ
せ、成形時の材料の流動によって大理石模様を得ていた
。In the conventional method of manufacturing artificial marble, in which a molding material made of a thermosetting resin with glass fiber and other additives and fillers is compression-molded under heating, a colored material is dotted in the molding material, The marble pattern was obtained by the flow of the material.
ところが、この方法は材料の金型内の流動による柄づけ
であるために、柄の安定性に欠け、金型の形状に柄が影
響されるという問題があった。However, since this method attaches the pattern by the flow of the material within the mold, there is a problem that the pattern lacks stability and is affected by the shape of the mold.
さらに、着色材料を成形材料中に点在するために混合を
充分に行うと、着色材料と成形材料とが完全に混じり合
ってしまうので分散が完全な状態まで行えず、そのため
柄の分散むらが起きるという問題もあった。Furthermore, if the coloring material is dispersed in the molding material and is sufficiently mixed, the coloring material and molding material will be completely mixed together, making it impossible to achieve complete dispersion, resulting in uneven distribution of the pattern. There was also the problem of getting up.
この発明は大理石模様を安定して得ることができる人造
大理石の製造方法を提供することを目的とする。The object of the present invention is to provide a method for producing artificial marble that can stably obtain a marble pattern.
この発明の人造大理石の製造方法は、成形材料表面に浸
透性着色インクを大理石柄状に印刷し、ついで前記成形
材料を型内に投入して圧縮成形することを特徴とするも
のである。The method for manufacturing artificial marble of the present invention is characterized by printing penetrating colored ink on the surface of a molding material in the shape of a marble pattern, and then putting the molding material into a mold and compression molding it.
前記成形材料としては、シート・モールディング・コン

て、これに染料を溶解して得ることができ、成形材料内
への浸透性にすぐれたものである。As the molding material, sheet molding compound (SMC), bulk ψ molding compound (BMC), etc. can be used, and these are preferably white. The colored ink to be printed on the surface of the molding material I can be obtained by dissolving a dye in a polymerizable vinyl monomer as a solvent, and has excellent permeability into the molding material.
大理石柄の印刷方法としては、たとえばシルクスクリー
〉による方法があげられるが、とぐに限定されるもので
はなく、いかなる印刷方法を用いてもよい。As a method for printing the marble pattern, for example, a method using silk screen printing can be cited, but the method is not limited to this, and any printing method may be used.
印刷した成形材料は単独または複数枚を重ね合わせて金
型内に入れ、加熱下で圧縮成形して所定形状の人造大理
石を得る。この人造大理石の表面には、印刷によって形
成された着色インクの柄に対応するマーブル調の模様が
表現される。The printed molding material is put into a mold either singly or in layers, and compression molded under heat to obtain an artificial marble of a predetermined shape. On the surface of this artificial marble, a marble-like pattern corresponding to the colored ink pattern formed by printing is expressed.
次に、実施例をあげて説明する。Next, an example will be given and explained.
実施例：熱硬化性のポリエステル樹脂に水酸化アルミニ

材料１を示しており、その内部に着色インク２が浸透す
る。Example: SMC (thickness 2 mm), which is a mixture of thermosetting polyester resin, aluminum hydroxide, and glass fiber, is used as a molding material, and colored ink obtained by dissolving violet dye in styrene monomer is applied to the surface of this SMC. It was printed in stripes by screen printing. FIG. 1 shows a molding material 1 after screen printing, into which a colored ink 2 penetrates.
ついで、第２図に示すように、成形材料１の複数枚を重

理石５を得た。このものはマーブル調の編柄が表面に形
成されていた。Next, as shown in FIG. 2, a plurality of sheets of the molding material 1 were stacked to form a block 3 having a thickness of 50 rRIB, which was placed in a mold 4 and hot-press molded. Molding is 150°
C, 40 Ky/crA for 15 minutes. In this way, a sheet-like artificial marble 5 having a thickness of 15 mm as shown in FIG. 3 was obtained. This item had a marble-like pattern formed on its surface.
この発明によれば、人造大理石の表面に大理石模様を安
定して形成することができるという効果がある。According to this invention, there is an effect that a marble pattern can be stably formed on the surface of artificial marble.
