Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is a lightweight and easy-to-install non-fired tile that exhibits excellent aesthetics and is used for decorative finishing materials such as pillars, inner and outer walls, flooring materials, gates, and walls of buildings.

[0002]

[Prior art]

 Conventionally, tiles must be fired with common sense that they are made of porcelain and energy was required. In addition, defective ceramic tiles generated during the production process had to be disposed of as industrial waste.

[0003]

[Problems to be solved by the invention]

 In this invention, from the viewpoint of energy saving and resource saving, scraps such as defective ceramic tiles generated during the production process are reused as pulverized particles and used as tiles with excellent appearance without firing Is provided.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of such circumstances, and a synthetic resin emulsion is added to crushed particles of ceramic waste to form a tile by pressure.

[0005]

[Embodiment of the invention]

 By pressing a composition composed of ground ceramic waste particles into a tile using a synthetic resin emulsion as a binder, the surface exhibits a stone-like or brick-like pattern of ground ceramic waste particles. By mixing various types of ground ceramic waste particles, it is possible to arbitrarily change the stone-like or brick-like pattern.

The synthetic resin emulsions used in the present invention include acrylic resin emulsions, vinyl acetate resin emulsions, vinyl chloride resin emulsions, vinylidene chloride resin emulsions, styrene / butadiene resin emulsions, epoxy resin emulsions, and acrylic resin emulsions. Examples include acid esters, styrene, ethylene, vinyl esters, vinyl acetate, and copolymers with synthetic rubber.

For example, copolymers of these include acrylic / vinyl acetate copolymers, vinylidene chloride / butyl acrylate copolymers, ethylene / vinyl acetate copolymers, and the like. The amount of the synthetic resin emulsion composition used is in the range of 5 to 8% by weight in terms of solids. If it is less than 5% by weight, the physical properties of the tile will not be improved, and if it is more than 8% by weight, the nonflammability of the tile will be reduced.

In the present invention, in addition to the above, various surfactants as a dispersant, an emulsifier for stabilizing an emulsion, an anti-fraying agent for an emulsion, a thickener, Anti-sagging agents, anti-settling agents, anti-freezing agents and the like may be added. Further, for the purpose of improving the performance of the tile, a plasticizer, a stabilizer for preventing deterioration due to heat and light, and a fungicide for preventing the occurrence of mold may be added.

[0009] The crushed ceramic waste particles used in the present invention are defective in the ceramic production process. Rare, concrete products are black clay tiles, bricks, clay pipes, pottery tiles, interior and exterior Porcelain, such as tiles, floor tiles, and ceramic pipes, includes interior and exterior tiles, floor tiles, mosaic tiles, and sanitary ware. These products are used to crush defective products and waste.

[0010] The ground ceramic particles are fine, medium, and coarse, and the fine particles have a particle diameter of 0.1 to 0.5 mm, a medium of 0.5 to 1.5 mm, and a coarse of 1.5 to 3 mm, respectively. Adjust to 4 mm before use. In addition to crushed ceramic waste particles, silica powder, fly ash, silica fume, clay, talc, kaolin, slow-cooled blast furnace slag slag, and siliceous dust may be added as necessary.

[0011] The color of the ground ceramic waste particles differs depending on the original ceramic product, and a unique texture can be exhibited by blending them in various ways. For example, the addition of a moderate amount of white sanitary garbage waste ground particles to the coarse and fine ground brick ground particles makes it possible to express a completely new tile pattern that did not exist before.

[0012] To obtain an excellent stone-grained or brick-like appearance and excellent design on a tile surface by pressing a composition composed of a synthetic resin emulsion and ground ceramic waste particles into a tile. Was completed.

[0013] The shape and dimensions of the unfired tile can be designed arbitrarily, the dimensions are free and varied, and square, rectangular, triangular, round and other special shapes are possible. The size can be any size and shape, from small mosaic tiles to large tiles of 1 m or more. The form includes a flat plate and one with an edge part that is partially joined.

[0014]

【Example】

 An embodiment of the present invention will be specifically described.

Example As a synthetic resin emulsion, 12% by weight of a synthetic rubber-modified acrylic copolymer emulsion (6% by weight in terms of solid content), 75.5% by weight of crushed ceramic waste particles, and organic additives (dispersants, etc.) 4 0.0% by weight, 3.5% by weight of inorganic extender, and others 5. The composition having a composition of 0% by weight or more was sufficiently mixed and stirred by a vacuum degassing kneader.

The crushed particles of ceramic waste were crushed particles of Sanshu roof tiles, and the particle size was adjusted to 10 parts by weight and 70 parts by weight. To this was added 20 parts by weight of a medium weight of white sanitary ware waste ground particles.

The composition was pressure-molded into a two-piece tile having a thickness of 12 mm and cured at room temperature for 24 hours, followed by buffing the surface. The pressure for the pressure molding was 50 kgf / cm ² , and FIG. 1 shows the unfired tile. This unfired tile was proved to have the same weather resistance and wear resistance as the physical strength of ceramic tiles and higher.

[0018]

[Effect of the invention]

 The unfired tile according to the present invention could achieve the following effects which could not be achieved by the prior art by pressing and molding the ceramic waste particles and the synthetic resin emulsion into a tile shape.

Despite being unfired by using defective resin ground particles generated during the production process of ceramics and using a synthetic resin emulsion as a binder, it has a performance comparable to that of fired ceramic tiles. I was able to make a tile.

By changing the composition of the crushed ceramic waste particles, it was possible to arbitrarily express various stone tones and brick tones of a natural stone style.

[0021] The ceramic waste discarded as industrial waste can be effectively used, and can be formed by non-firing, so that the energy saving effect can be made extremely high.

The surface of the non-fired tile was able to exhibit a stone-like or brick-like appearance and excellent design properties, and further excellent texture was achieved by buffing.

The surface of the unfired tile is high in hardness and hard to be scratched, and can express the same texture as natural stone or brick. Further, since it is strong against acid, it is not contaminated by acid rain.
