Description

DETAILED DESCRIPTION OF THE INVENTION In place of the conventional ceramic tiles made mainly of china clay, clay, etc. by molding and high-temperature firing, the present invention uses cement, gypsum, carbonated magnesilano, etc. as water and water consumable tiles. The main material is resin concrete, etc., whose binder is an inorganic material that hardens by reaction, or a thermosetting resin that hardens at room temperature or low temperature heating, such as polyester resin or acrylic resin, and extrusion molding eliminates the need for continuous firing. This paper relates to a method for manufacturing tiles.

Conventional tiles are durable materials that create a relatively smooth wall surface, and are rich in color tones, color schemes, and other designs.
It is a useful material as a construction material for the purpose of upgrading floor tiles and the like. However, in the case of both porcelain tiles and porcelain tiles, it is safe to use stone pottery stone, feldspar, etc. as raw materials and fire them in a tunnel oven at a high temperature of around 1000'C for a long time. In other words, it cannot be said that even if raw materials (1) are low in price, the cost of the fuel required for firing dwarfs the cost with the increase in energy costs such as oil prices, and today energy conservation is encouraged.

The aim of the present invention is to create a non-fired tile manufacturing method using a main raw material such as cement that becomes stale at room temperature or low temperature, which is completely different from the conventional molding method using a press or the like. By extruding a set of screws at room temperature, we can continuously and efficiently form a 3D pattern on both sides of the front with a freely designed design at the same time as extrusion, and we also form a 3D pattern on the back to assist in adhesion. It is an object of the present invention to provide a method for manufacturing fired tiles.

The method of the present invention will be explained in detail below according to the attached screen 1111.

Figure (1) is a side sectional view of an example of a tile to be manufactured by the method of the present invention, the size is 10 oz square, the thickness is usually 5 to 7X according to the JIS standard, and the surface has a three-dimensional pattern (1).
The depth is usually about 0.5 to 1.0.

Figure (2) is an example of a process chart for extrusion molding of a hydraulic inorganic material such as ordinary cement. In FIG. 2, (2) is a raw material that has been mixed and kneaded in a pre-caulking blender, kneader, etc., and is fed in a fixed amount from a hopper (3) of an extruder. On the one hand, raw materials include hydraulic inorganic materials such as cement and gypsum, and an example of a mixture is Portland cement 100 parts asbestos.
20 parts silica sand
300 parts methylcellulose 1 part water
It has a suitable amount of composition, and in this type of material, it corresponds to noncombustible material. On the other hand, polyester if #I resin or acrylic m (J
It is mainly composed of IF, etc., and is a synthetic resin that can be cured at room temperature or by heating.The compounding material is polyester 41 [5 days, 100 parts Charcoal/Rum]
It has a composition of 200 parts aluminum stearate, 5 parts methyl cellulose, 1 part, and when I#i, the material is semi-nonflammable. The materials supplied to the hopper (3) are transported by the upper screw (
In the vacuum degassing chamber formed by (5), the mixture is kneaded and fed by (4),
The air mixed in during stirring is degassed and brought down, kneaded and extruded by an extrusion screw (6), passed through a press-fit tapered tube (7), and then passed through a die (8) having a desired cross section.
), the extruded continuous molded product (9) moves on the conveyor (10),
The pallets are conveyed on the pallet conveying conveyor (13) installed at the bottom of After being cured using a curing method according to the characteristics of each material, the rice cakes are transferred to a pallet and then plated. This is the normal extrusion molding process, but in this process, (
8) The structure of the die is shown in Fig. 3 as a front view and as shown in Fig. 4 as a side view. Roll (17
), (18) are prepared, and the upper roll (17) is, for example, 1
If it is an interior tile of 0c, it is engraved by embossing a three-dimensional cross-section of the surface of the tile with a pattern of 3 vertical rows and 3 horizontal rows, that is, a certain arbitrary number of units such as about 300 x 300, and the F part roll is in line with this. The pattern for embossing the surface pattern, for example, as shown in FIG. 5, is a pattern engraved to help the material sink into the ground during construction 1, and is made to match the pattern on the upper roll.

Both rolls (17) and (18) are installed at the exit of the extrusion molded product at the end of the die so that the molded product is assembled perpendicular to the extrusion direction, and the rough cutting is performed between the largest convex portions of the embossed pattern portions of both rolls. L1, which is the minimum value for extruded products. ・The J-method is designed to have a thickness that is so thin that it will not stretch or break during pick-up and transportation immediately after extrusion, and For both rolls (17) and (18) are Ryokawa (19)
, (20) or a chain or other transmission system so that they rotate at the same circular speed in opposite directions.Usually, both rolls (17) and (18) are used to extrude the material, and by pressure, the extrusion speed of the material and the like are controlled. They rotate in sync, but if the diameter of the rolls is large, the upper roll (19) and the lower roll (18) may be rotated by a torque motor on either side. Rotation torque may be applied to assist the rotation.In this way, the plate extruded from the ion material inlet (21) through the die has a three-dimensional tile pattern on its surface, and a pattern on the tile itself. It is a continuous plate-like material, and it is either punched out into individual units using a punching press such as a Furikun Yong press while it is still soft immediately after extrusion, or it is cured according to the material and then hardened using a rotating machine. etc. to obtain individual unit tiles.The upper and lower rolls are adjusted in height by the upper and lower rolls (22) and (23), respectively.

In addition, after folding or before cutting, in the case of cement-based materials or other materials, apply a primer, perform multicolor printing by screen printing, multicolor flexo printing, multicolor offset printing, etc., and then apply ultraviolet rays. When a hardening type acrylic or urethane resin paint is applied to the entire surface and then irradiated with ultraviolet rays using an ultraviolet irradiation device, a hard surface coating film with a pencil hardness of about 2H to 4H is obtained. The ultraviolet curing reaction does not involve heating, and even if it does, the temperature is 40 to 60°C, and it does not affect the physical properties of the raw material of the present invention and does not cause deformation, bending, etc. The appearance is similar to that of fired tiles.

This is Hongyo's second invention, a non-fired decorative tile.The hardness is the key factor, so it is hard to get scratches, and the hardened film is formed on a non-flammable or semi-non-flammable material.
There is no danger of combustion even when used on the walls of kinochino, buses, etc. It has exactly the same aesthetic appearance as regular fired tiles. Moreover,
Because of this UV-cured protective film, the printed pattern on the base will not disappear, allowing it to maintain its beautiful appearance for a long time.

FIG. 6 shows a cross section of an example of a non-fired decorative tile, in which (9) is a non-fired tile substrate manufactured by the method of this patent, (24) is an alkali sealer or primer,
(25) is a printing ink, and (26) is an ultraviolet ray-containing chemically cured film.
