Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stone-tone composite material that can be used as a wall material for buildings.

[0002]

[Prior art]

 Plate-shaped wall materials used for the exterior and interior of buildings include plate-shaped processed products of natural stone and artificial marble, or the surface of base materials of plywood and ceramic products, sheet-shaped or sheet-shaped products. Decorative processed products with a decorative material attached are used as wall materials for the dry method.

[0003] In recent years, as a stone-grained composite material, white cement or synthetic resin adhesive is used as a binder, and aggregates such as cold water stone and silica stone are mixed on a plate-shaped substrate surface such as plywood. There is also a sand-walled composite material in which cement mortar or resin mortar is sprayed or ironed.

[0004]

[Problems to be solved by the device]

 However, wall materials made of natural stone or artificial marble have the drawbacks of being expensive, heavy, and poor in machinability. In addition, painted finishes and processed products with decorative materials tend to have monotonous wall surfaces and have a defect in decorative effect. In addition, the appearance of the sand wall composite material as described above is such that a speckled pattern appears on the surface, and does not have an appearance having a reflection light surface peculiar to natural stone.

An object of the present invention is to provide a stone-tone composite material which is relatively lightweight, has good cutting and adhesive workability, and has a reflection light surface peculiar to natural stone.

[0006]

[Means for Solving the Problems]

 The present invention is a surface layer obtained by mixing mica and transparent or translucent beads in synthetic resin through a middle layer mainly composed of synthetic resin and aggregate on a sheet-shaped or plate-shaped substrate. Is a stone-grained composite material that forms

Next, the present invention will be described with reference to the side sectional view of FIG. The sheet-shaped or plate-shaped base material 1 in the present invention includes wood products such as plywood and particle boards, ceramic products such as gypsum boards and silica boards, and sheets such as paper and non-woven fabric. A sheet or plate-shaped substrate having good machinability, which is used as a substrate for construction such as a sheet-shaped substrate, is applied.

The intermediate layer 2 formed on the surface of the sheet-shaped or plate-shaped base material 1 is obtained by fixing a coating material containing a synthetic resin 21 and an aggregate 22 as main components. Is an acrylic, epoxy, urethane, unsaturated polyester, vinyl ester, or other room temperature or active energy ray curable resin, and is a synthetic resin for paints that has excellent adhesiveness and physical and chemical properties. Is applied.

As the aggregate 22, particles or powder having a particle size of 0.05 to 5 mm, such as cold water stone, silica sand, natural stone, marble, artificial aggregate, and lightweight aggregate (hollow body), are applied. Wood is also applied.

The synthetic resin 21 and the aggregate 22 are mixed at an arbitrary ratio within a range of 100 to 300 to 1000 in terms of solid content weight.

The surface layer 3 is formed by fixing a coating material in which mica 32 and transparent or semitransparent beads 33 are mixed in a synthetic resin 31, and the synthetic resin 31 is an acrylic type or an epoxy type. It is a room temperature or active energy ray curable resin such as urethane type, unsaturated polyester type or vinyl ester type, which has excellent adhesiveness and physical and chemical properties. There must be. The synthetic resin 21 for the intermediate layer 2 may be the same or different, and the same type of resin is suitable from the viewpoint of adhesion to the intermediate layer 2.

The mica 32 is an adjoining biotite granite having a grain size of 0.5 to 6.0 mm, and is a white-walled Kali feldspar, soda plagioclase, thin gray quartz, or black phosphorus. It has a crystal structure with each component such as the shape of biotite, and the crystal plane consists of a plane. When mica (black, brown, silver, gold, red, etc. that develop color depending on a specific temperature) is added to the resin and some of the mica pieces are present in the resin so as to incline, the appearance of natural stone appears. You can get something close to.

As the transparent or translucent bead 33, a transparent glass bead having a particle size of about 0.1 to 3.0 mm can be used. The semitransparent beads include inorganic fillers such as silas balun and fly ash foam, and plastic beads such as silicone resin and epoxy resin.

The mixing ratio of the synthetic resin 31, the mica 32, and the transparent or translucent beads 33 forming the surface layer 3 is a solid weight conversion value, and the mica is 2 to 10 with respect to 100 parts of the synthetic resin. 20 to 100 parts in the case of parts and glass beads, and 8 to 40 parts in the case of plastic beads having a specific gravity of 1.0.

As the method for producing the stone-tone composite material of the present invention, the surface of the base material 1 is treated with a sealer or an adhesive 4 if necessary, and the synthetic resin 21 and the bone forming the intermediate layer 2 The liquid mixture of the material 22 is applied and formed by means such as spraying, roller, iron coating, and flow coater method, and the surface layer 3 is formed after drying at room temperature or by heating. It can be obtained by applying a mixture of the synthetic resin 31, mica 32 and beads 33 by the above-mentioned means.

It should be noted that if the interface between the intermediate layer 2 and the surface layer 3 has irregular irregularities, the appearance of a stone tone looks three-dimensional, giving a feeling similar to natural stone.

[0017]

[Effect of device]

 The stone-grained composite material of the present invention exhibits a stone-grained appearance having a unique reflected light surface due to the aggregate of the intermediate layer and the mica and transparent or translucent beads in the surface layer, and Since the base material is sheet-shaped or plate-shaped, secondary processing such as cutting and bonding is easy, and it is useful as a building material for construction or construction.
