産業上の利用分野
本発明は、断熱性、防音性に優れるとともに所望の色に
着色された着色パーライトの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for producing colored pearlite which has excellent heat insulation and sound insulation properties and is colored in a desired color.

向上させていた。Conventional technology Pearlite, which is made by crushing and firing pearlite raw stones such as pearlite, obsidian, and pinestone, is a glassy foam with closed pores, and is used in concrete because it is lightweight and has excellent heat and sound insulation properties. It is widely used as aggregate and heat insulating material, but because it is white, when used on indoor ceilings and walls, it is necessary to coat the surface with pigment or mix pigment into the adhesive. It was colored to improve its aesthetic appearance.
発明が解決しようとする課題
しかしながら、パーライトの表面に顔料をコーティング
したものは、パーライトが破壊された場合に白色の粉末

た。Problems to be Solved by the Invention However, products in which the surface of pearlite is coated with pigment have the disadvantage that when the pearlite is destroyed, it becomes a white powder, resulting in uneven color. This method has disadvantages of high cost and low durability depending on the MtR of the pigment.
課題を解決するための手段
本発明はこのような課題を解決するための手段として、

を含浸させ、焼成して発泡させる構成とした。Means for Solving the Problems The present invention provides the following means for solving the problems.
The structure is such that pearlite ore is crushed, impregnated with a pigment made of water-soluble metal salts, and then fired and foamed.

る。Effects of the Invention The present invention has the above-mentioned structure, and since the ore is crushed and impregnated with water-soluble metal salts as a pigment, it not only adheres to the surface but also penetrates into the interior by capillary action and develops color by firing. Even when pearlite is destroyed, it becomes a colored powder and no uneven coloring occurs.Therefore, pearlite produced by the method of the present invention can be used on ceilings and walls coated with adhesive. By spraying with pressurized air or spraying with adhesive, particles colored in the desired color can be attached, which has the effect of soundproofing and heat insulation, and is particularly effective in preventing earthquake condensation. In addition, since it can be colored in a desired color, it has the effect of improving the aesthetic appearance of the room.

ある。Examples Water-soluble metal salts used as pigments in the present invention include cobalt chloride, iron chloride, chromium chloride, etc., and may be appropriately selected depending on the desired color development.
The aqueous metal complex salt solution for ceramic coloring sold by 5ER-KNAPSACK under the trade name MERAPON is extremely suitable because it does not generate corrosive gas during firing.
