A granulated aggregate for wall materials containing a core material, a filler, and a binder is disclosed in Japanese Patent Publication No. 30829/1982. This conventional technology involves stirring and mixing sand as a core material, filler, pigment, and binder using a predetermined stirrer, thereby abrading the sharp protrusions of the sand and spreading the filler, pigment, etc. into the recessed parts. In this method, a granulated aggregate for wall materials having a nearly spherical shape is obtained by attaching the particles and spreading them over the entire surface. Therefore, this prior art is an excellent invention in that it processes sand having acute angular protrusions to obtain a granulated aggregate for wall materials having a nearly spherical shape. However, the purpose of this conventional technology is to obtain a granulated aggregate for wall materials that has a rich sense of mass, and is different from the present invention, which aims to obtain a lightweight granulated aggregate for wall materials. It is something. Note that the core material used in this conventional technology is one with a high bulk specific gravity such as natural stone, crushed stone, and kansui stone.
Further, the amount of filler is small at 2 to 20% by weight based on the core material.

との理由から、これらが壁材用造粒骨材の芯材と
して使用されたことはない。 On the other hand, in order to reduce the weight of wall materials, the use of porous materials and fibrous materials has been practiced for a long time. However, it is not possible to obtain granulated aggregate for wall materials with a stable color due to the uneven absorption of spread materials (fillers, binders, pigments, etc.) by the core material. It has never been used as a core material for granular aggregate.

In view of the problems of the prior art described above, the inventors of the present invention conducted various studies to achieve the intended purpose, and as a result, they finally succeeded in obtaining the granulated aggregate for wall materials according to the present invention.
即ち、本発明に係る壁材用造粒骨材は、次の特

る。Core material bulk specific gravity (x): 0.5-1 Particle size: 14 mesh or less and larger than 42 mesh is 70% or more Filler particle size: 100μ or less Blend amount: 360/x when granulating 1Kg of core material
~800/x One of the characteristics required of the core material used in the present invention is that the bulk specific gravity (x) be in the range of 0.5 to 1. If the bulk specific gravity (x) is too small, the core material may be broken or damaged by the pressure of a trowel during painting work, resulting in a lack of practicality as a granulated aggregate for wall materials. On the other hand, if the bulk specific gravity (x) is too large, weight reduction, which is one of the objectives of the present invention, cannot be achieved. Therefore, the bulk specific gravity (x) of the core material used in the present invention is limited to the above range. Examples of the core material within this range include hard pearlite, foamed granules of ore represented by pumice, fired granules of ore, and molded or foamed plastic granules.
また、本発明において使用する芯材に要求され

る。 Another characteristic required of the core material used in the present invention is that the core material has a particle size of 14 mesh or less and contains 70% or more of particles larger than 42 mesh. If the particle size is too coarse,
It is necessary to have a thickness of 14 mesh or less because the workability of painting as a wall material is poor and the wall surface after painting becomes rough and lacks elegance. However, if the particles are too fine, it will not be possible to granulate them, and if the proportion is too large, it will not be possible to obtain a stable color tone for the entire wall surface, so it is necessary that 70% or more of particles larger than 42 mesh be contained. be.
なお、本発明において使用する芯材は、前記特

とは云うまでもない。 It goes without saying that the core materials used in the present invention may be used not only singly but also as a mixture of two or more types, as long as they satisfy the above characteristics.
本発明において使用するフイラーとしては、例

このフイラーについても次の二つの特性が要求さ

得難くなるからである。また、前記した上限を越
えても造粒物を得られることもあるが、造粒物の
表面の滑らかさに欠けることになり、塗装作業性
が劣ることになる。 Examples of the filler used in the present invention include clay, talc, calcium carbonate, and kaolin. In the present invention,
This filler is also required to have the following two characteristics. One of them is that the particle size is less than 100μ. If it is larger than this,
This is because the specific surface area becomes smaller, making it difficult for the filler to adhere to the surface of the core material, making it difficult to obtain granules with a shape close to spherical. Further, even if the above-mentioned upper limit is exceeded, granules may be obtained, but the surface of the granules will lack smoothness, resulting in poor coating workability.
また、本発明において使用するフイラーに要求
されるもう一つの特性は配合量であり、１Kgの芯

であるということである。比表面積が小さい芯材

多過ぎると、余剰分のフイラーが展着できずに遊
離し、芯材に均質に固着し難くなる。 Another characteristic required of the filler used in the present invention is the blending amount, which is in the range of 360/x to 800/x when 1 kg of core material is granulated. When using a core material with a small specific surface area, the lower limit amount is sufficient, and when using a core material with a larger specific surface area, the upper limit amount is sufficient. The filler content is
If it is too small than 360/x, it will be difficult to obtain a stable color tone no matter what shape the core material is. On the other hand, if the blending amount of the filler is more than 800/x, the excess filler cannot be spread and becomes loose, making it difficult to uniformly adhere to the core material.
なお、本発明において使用するフイラーは、前
記特性を満足するものであれば、単独使用のみで
なく、二種以上のものを混合して使用してもよい
ことは云うまでもない。 It goes without saying that the filler used in the present invention may be used not only singly but also in a mixture of two or more types, as long as it satisfies the above characteristics.

ルや水を添加すればよい。 In addition to the core material and filler described above, the essential components constituting the granulated aggregate for wall materials include a binder. As this binder, one that is commonly used in manufacturing this type of granulated aggregate for wall materials may be used in accordance with a conventional method. Typical examples include synthetic polymers such as acrylic resin, vinyl resin, epoxy resin, urethane resin, polyester resin, polyamide resin, and silicone resin. These resins can be used alone or in combination. Since solvent-based emulsions have problems in terms of occupational health and environmental safety, resin emulsions that do not have these problems are suitable. Furthermore, from a practical standpoint, it is preferable to select one with excellent water resistance. Note that if the binder does not contain a solvent or if it contains a small amount of solvent, alcohol or water may be added.

This coloring agent can be arbitrarily selected from among those used as raw materials for dyes and inks, such as dispersed pigments, powdered pigments, and dyes, but it is easy to adjust the color and improve the color tone. In view of effectiveness, it is particularly preferable to use dispersed pigments. In addition, as special materials, pearl pigments and metallic materials such as aluminum powder can also be used.

を混入してもよい。 In order to obtain the granulated aggregate for wall materials according to the present invention, the binder, solvent, coloring agent, etc. are stirred in advance to form a dispersion liquid, and the surface of the core material is uniformly wetted with this, and then A predetermined amount of filler may be added, stirred using a stirrer, and dried. Further, the dispersion liquid and the filler may be used separately, for example,
A portion of the filler may be added after wetting the core with a portion of the dispersion, followed by the remaining dispersion and then the remaining filler. In this case, the color tone of the granulated aggregate for wall materials is mainly controlled by the colorant in the dispersion that is added later, so the colorant is not mixed in the dispersion that is added first, and The entire amount of the colorant may be mixed into the dispersion liquid added from.
