粒子状顔料でせつこうを着色する方法に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for coloring plaster with a fine particulate pigment in order to color code plaster molds, judge mold separability in the manufacturing process of plaster molds, etc. Regarding the method.
従来、顔料の粉末をそのまませつこうに混入し
ていた。
Previously, pigment powder was mixed directly into plaster.
しかし、微粒子どうしの混合のために顔料の分
散性が悪く、均一混合に長時間を要したり、色ム
ラが生じやすい欠点があつた。
However, due to the mixing of fine particles, pigment dispersibility is poor, it takes a long time to mix uniformly, and color unevenness tends to occur.
本発明の目的は、せつこうと顔料の均一混合を
短時間で行え、かつ、色ムラが生じにくい、優れ
たせつこうの着色方法を提供することにある。 An object of the present invention is to provide an excellent method for coloring plaster that can uniformly mix plaster and pigment in a short time and is less likely to cause color unevenness.
本発明の特徴手段は、微粒子状顔料を有機材料

その作用効果は次の通りである。
The characteristic means of the present invention is that a fine particulate pigment is attached to the surface of spherical particles made of an organic material, and the spherical particles to which the pigment is attached are mixed into plaster.
Its effects are as follows.
つまり、顔料を付着させた粒子は分散しやすい

In other words, the particles to which the pigment is attached have a spherical shape that is easy to disperse, and the spherical particles can be appropriately selected to have a particle size that provides good dispersibility. Particles can be mixed in, and furthermore, fine particulate pigment attached to each spherical particle can be uniformly dispersed and mixed into plaster in a short time. At this time, the spherical particles dispersed in the plaster are exposed not only inside the plaster but also on the plaster surface. Therefore, for example, when pouring plaster into a plaster mold and solidifying it, since the spherical particles are made of an organic material, plaster, which is an aqueous material, is difficult to mix with the spherical particles, and therefore, the plaster mold Hard to stick to surfaces. As a result, the mold separability between the newly solidified plaster and the plaster mold becomes high.
その結果、せつこうと顔料の混合を作業能率良
好にかつ確実に均一に行え、色ムラの無い良質の
せつこう型を容易迅速に造れるようになつた。ま
た、前記せつこう型は型分離性が高いものとなる
ので、手軽にせつこう製品を製造することができ

As a result, plaster and pigment can be mixed reliably and uniformly with good work efficiency, and high-quality plaster molds with no color unevenness can be easily and quickly produced. Moreover, since the plaster mold has a high mold separability, it has become possible to easily manufacture plaster products.
