Description

TILES AND METHOD OF MANUFACTURING THEREOF FIELD OF THE INVENTION [0001]

The present invention relates to a tile and a manufacturing method thereof.

Fiber Reinforced Plastic (FPR) is a thermosetting plastic that can be recycled and can not be recycled since it is insoluble when it is set in any shape (bridging, vulcanization, hardening) . However, in general, it has a good mechanical property, electrical property, water resistance, chemical resistance, lightness and rust resistance, and high noble strength, so that it is widely used throughout the industry.

Since 2004, waste plastic waste (abbreviated as 'waste FRP'), which is abandoned in Korea, is now consuming more than 50 billion won a year, accounting for more than 2.5 million tons of waste.

As a method of treating waste FRP at present, there is a method of embedding only the remaining glass fiber after incineration, a mechanical method using residual aggregate after crushing, and a strong acid to separate a laminated layer of waste FRP to obtain a resin, And a chemical method in which a compound is additionally obtained by hydrolysis.

However, since this method uses strong acid, there are many risk factors such as FOSHAN LEAK, and all of these methods are not economical, and the treated wastes are buried in the soil and the sea. Therefore, secondary pollution is caused with lack of landfill It has a negative environmental impact.

To solve this problem, in many countries, waste FRP is divided into thermal, chemical, biological treatment or material recycling in order to be recycled. It is pointed out that double thermal recycling is a method of using heat obtained by incineration of waste FRP for power generation or heating, and economical efficiency due to air pollution and incineration facilities, and chemical recycling is a method of recovering and recycling raw materials by pyrolyzing waste FRP at high temperature It is still in the research stage.

Biological treatment methods are extremely limited in their use as methods for decomposing or developing materials that can be easily disassembled from the beginning. In addition, material recycling is a method of recycling waste plastic as a raw material for producing new materials by vertically separating the thermoplastic resin. The thermoplastic resin is cut and re-fused to be used in the production of building materials such as artificial wood and waste water pipes. The thermosetting resin is pulverized And it is recycled as a material without causing environmental pollution by using it as a substitute for fine aggregate of various concrete products, filling material of paints or resin products, sound absorbing material, impact resistant material, etc. Therefore, It is progressing.

However, these methods are mostly in the research stage, and there is not a lot of data to be written. Therefore, in order to effectively treat waste FRP, environmentally friendly and high value-added processing methods are required.

KR 1998-063390 A

In the past decades, the treatment of fiber-reinforced plastic wastes has resulted in serious ocean and soil contamination due to landfilling through crushing and incineration.

The specificity and features of the present invention will become more apparent from the following detailed description and examples, which are to be taken in conjunction with the accompanying drawings. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. Also, terms such as "first", "second", "one side", "another side" and the like are used to distinguish one element from another element, and the element is not limited thereto . DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the accompanying drawings.

The tile according to one embodiment of the present invention is formed by using a paste in which a fiber reinforced plastic waste (hereinafter referred to as 'waste FRP') powder and a resin are mixed. Therefore, these tiles have the characteristics of fiber-reinforced plastic, so that they have a long life span, are not only light but also strong and not easily decayed.

Here, the tile includes a surface formed by a square hexahedron having a small thickness and exposed to the outside, a back surface formed on the opposite side of the surface to be adhered to a wall surface or a bottom surface, and a side surface connecting the front surface and the back surface A concave portion may be formed on the back surface, or a pattern may be formed on the surface. That is, it is possible to improve the adhesion with the object to be adhered through the concave-convex portion, and it is possible to enhance not only the differentiation from the other products through the surface pattern, but also the aesthetics.

Meanwhile, a method of manufacturing a tile according to an embodiment of the present invention is a method of injecting a paste made into a mucilage form by mixing powder produced by grinding waste FRP with a resin into a mold, It is possible to paint the surface of the tile in advance by coating the gel coat, and the surface mat can be impregnated with the resin to remove bubbles.

Therefore, the waste FRP, which is normally incinerated or buried, can be easily recycled into tiles, thereby saving the cost for treating the waste FRP as well as protecting the environment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the tile 10 according to an embodiment of the present invention includes a body 11 formed of a square hexahedron. The body 11 is formed by using a paste in which waste FRP powder and a resin are mixed and has a back surface 12 attached to a wall surface or a bottom surface and disposed on the opposite side of the back surface 12 A surface 13 exposed to the outside is formed and a side surface 14 connecting them is formed to constitute the tile 10.

The back surface 12 of the body 11 has a concave and convex portion 12a to improve the adhesion and not easily separate from the wall surface or the bottom surface. In the case of the concave and convex portion 12a at this time, . The surface 13 of the body 11 is patterned so as to have an esthetic appearance as it is exposed to the outside. In the case of the pattern, a free coat is formed using a gel coat.

The tile according to one embodiment of the present invention can be formed by the following manufacturing method, which will be described with reference to the accompanying drawings.

3 to 8, in order to manufacture the tile 10, first, a mold 20 having a cavity 20c is prepared. The mold 20 has a cavity 20c having the same shape as the tile 10, The front mold 20a and the rear mold 20b are separately prepared.

The rear mold 20b is provided with a concavo-convex pattern on the cavity 20c so as to form a concavo-convex portion 12a on the rear surface 12 of the tile 10, And the glass fiber sheet is impregnated with the resin to remove the air bubbles. The front mold 20a is coated with a gel coat on the cavity 20c so that a pattern is formed on the surface 13 of the tile 10. [

On the other hand, when the mold 20 is prepared as described above, the waste FRP is pulverized by a grinder and mixed with a general synthetic resin to form a paste of a mucilage type. Then, the paste 22 is poured into the cavity 20c of the rear mold 20b and pressed against the front mold 20a.

When the paste 22 is completely hardened in the process of pressing the front mold 20a as described above, the front mold 20a is separated from the rear mold 20b and then the tile 10 is demolded to manufacture the tile 10 .

Hereinafter, the experimental results of collating the waste FRP tile with the ceramic tile according to an embodiment of the present invention are as follows.

As a result of measuring the weight and thickness of two specimens (300 mm × 300 mm) in order to know the physical properties of a general ceramic tile, it was confirmed that the weight of both specimens was about 1.5 kg and the thickness was about 9 mm. For the specimen shear test, the ceramic tiles were cut into 75 mm and shear strength was tested using three specimens.

Figure 112014060811094-pat00001

Next, to determine the physical properties of the waste FRP tile according to an embodiment of the present invention, the weight and thickness of the specimen (300 mm × 300 mm) of the same standard were measured. As a result, It was confirmed that the thickness was about 6 mm. For the specimen shear test, the ceramic tiles were cut into 40 to 45 mm each, and shear strength was tested using three specimens.

Figure 112014060811094-pat00002

As shown in the above table, a typical ceramic tile has an average strength of 22.86, whereas a waste FRP tile has a strength of about 45.53, which is about twice that of a conventional ceramic tile. Especially, since ceramic tile has a high modulus of elasticity, it can be easily broken at the time of work.

According to the test results, although the waste FRP tile is manufactured using waste powder recycled as a main component, it is generally lighter in weight than a commercially available ceramic tile, has a strength twice as strong as that of a commercially available ceramic tile, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention. It will be apparent that modifications and improvements can be made by those skilled in the art.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
