Description

[Detailed Description of the Invention] (Objective of the Invention and Problems of the Prior Art) This invention relates to the construction of paving stones to be laid on the soil surface of an aquarium for breeding ornamental fish or potted plants. Conventionally, natural gravel or cobblestones have been used as paving stones laid in aquariums for ornamental fish.

However, as potted plants for aquariums and ornamental plants are placed indoors, it is a good idea to color them in green, white, red, blue, etc. to enhance the effect of cobblestones and other paving stones. It is being

Therefore, since the coloring of natural paving stones does not have sufficient color saturation and the coloring effect is difficult, paving stones based on plastic materials are being considered as an alternative paving stone material.

However, because synthetic resin paving stones have a low specific gravity, they have the disadvantage of floating or scattering in water, resulting in a lack of stability.Also, they are more expensive than natural stones, making them impractical.

The purpose of this invention is to provide a new and effective paving stone material that has been solved through many tests in order to improve the problems of the above-mentioned plastic paving stones.

(Structure and Examples of the Present Invention) The gist of the present invention is to form granules made of plastic or rubber as a base material, colored by adding fillers and colorants, or solidified into cobblestone-like or other suitable shapes. It is something to be molded.

That is, plastic or rubber materials (including synthetic rubber) are used as the base material, and fillers and coloring agents such as pigments and dyes are added as extenders to this material and solidified to form paving stones of appropriate colors such as green, red, and blue. It is something.

Examples of fillers include carbon black, calcium carbonate, barium sulfate, diatomaceous earth, coal ash,
Clay, silica, calcium silicate, white carbon, cellulose, lignin, asbestos, mica, quartz powder, slate powder, glass powder, and other materials are used as materials, and among these fillers, fillers with strong water resistance and molecular bonding properties are used. They are appropriately selected and mixed, pigments and dyes are added as colorants, and the materials are solidified into paving stones.

The suitable size of the paving stones is about 2 mm to 20 mm, but there are no particular restrictions on the size or weight of the paving stones.
As shown in the examples in Figure 1 a to e, the shape may be an appropriate shape such as a sphere or an ellipse, or it may be used as a paving stone with protrusions formed in a rectangular or hexagonal shape or a spherical shape like confetti for stability and taste. Possible things may also be figurative.

The mixing ratio of plastic and filler is 10% to 90% plastic material and 90% to 10% filler. The specific gravity of solidified paving stones is 2 to 10 times that of plastic.

The paving stone material formed in this way is used to raise goldfish, tropical fish, etc. by laying granules or cobblestones 1 on the bottom of the aquarium 2 as shown in the drawings of the embodiment, but the color changes with the water in the aquarium. It is effective.

(Effects of the present invention) The present invention is used as a paving stone material to be set in aquariums, potted plants, and other devices and places that require cobblestones, and has the following features and advantages over conventional paving stone materials.

First, since the specific gravity increases dramatically, the problems of floating or dissipating even when installed in water are completely eliminated.

In addition, since the material has excellent colorability and dyeability, the color of the paving stones is clearly displayed, enhancing the color effect of aquariums and flower pots, and serving as a fashionable indoor set for aquariums and the like.

In terms of price, since the material cost is low, the production and processing costs are low, and it can be provided as a paving stone material with many features and advantages, such as excellent practical economic efficiency.
