Description

Tile including citrus peel pulp and manufacturing method thereof {Tile including citrus peel pulp and Manufacturing method of the same}

The present invention relates to a tile comprising a citrus foil pulp and a method of manufacturing the same, and specifically, by mixing citrus peel and pulps with citrus peel, the excellent firmness and humidity control function of the Korean paper and the color and aroma of the citrus foil. Of course, the present invention relates to paper tiles which simultaneously exhibit functions such as antimicrobial activity.

Recently, as the quality of life has improved, interest in interiors has increased for a more comfortable and personalized living environment. In the process of changing the interior, even the new building's interior materials, which have never been used, are often removed and newly installed, and most of the demolition interior materials are made of wood, stone, or wallpaper, which can be difficult to dispose of. Even if it is, the cost of disposal is not negligible, and it has an adverse effect on the environment such as generation of harmful gases such as dioxins.

In addition, the wood used in the interior is commonly used for chemical preservatives for the preservation or by using a formalin treatment process, residual harmful substances are released even after construction to contaminate the indoor air, widely used for wall decoration The wallpaper also contains chemicals contained in the raw material itself or used in the printing process, which may act as a source of indoor air after construction. Since the stone itself contains a large amount of harmful substances, volatile organic compounds (VOCs) emitted from building materials or finishing materials accumulate indoors when ventilation is inadequate, especially in winter, with atopic dermatitis, asthma and headaches. It is a cause of the syndrome, and it is known to emit harmful substances over a long period of time, which takes 2 to 4 years to reduce the amount of VOC contained in building materials by half. In order to minimize sick house syndrome, a ventilation facility for forcibly evacuating indoor air, an air cleaner, or a harmful gas reduction technology using a photocatalyst have been used. However, the effect is still not meager, and additional equipment is needed or expensive to maintain when using ventilation facilities or air purifiers, and photocatalytic coating requires more fundamental problem solving, such that the function is lost due to abrasion. Do.

As a solution, a technology related to a tile made of paper has been developed. For example, in the method of manufacturing a molded product using waste paper of Korea Patent Publication No. 2004-25982, after compression molding and heat drying by mixing waste paper and a binder, Provided a method of manufacturing a molded product by applying and heating and drying the infrared ray generator and ceramic (or Teflon) step by step, and in the manufacturing method of building interior materials using the waste paper of the Republic of Korea Patent Publication No. 2005-37793 shredded waste paper in two steps After dissociation and extraction of pulp, the mixture was formed by mixing with volcanic stone powder, gypsum, a water-soluble adhesive, and a waterproofing solution, and then spraying and drying additives such as an antibacterial agent and a flame retardant to provide a method of manufacturing a building interior agent. The above techniques commonly provide a method of manufacturing interior materials such as tiles using paper, but in the case of the above techniques, the functional part is limited to the coated part, not the product itself, and the functional part is worn when the surface is worn out for a long time. This may fall, and there is a limit that it does not exhibit high strength due to the short fiber length because it uses pulp prepared from waste paper.

In the present invention, the pulp as a main component to provide a method of producing an environmentally friendly tile with less emissions of harmful substances during use as well as after disposal.

In addition, the present invention is antimicrobial, anti-fungal and excellent deodorizing power, there is a far infrared radiation and anion emitting function, to provide a tile that can create a healthy indoor environment and prevent sick house syndrome.

The present invention provides a tile comprising a citrus foil pulp and a duck pulp and a method of manufacturing the same by mixing cooked citrus fruit and Doc pulp.

The duck pulp constituting the tile according to the present invention has a characteristic of excellent strength because of its long fiber, pH of weak alkalinity, and low content of lignin, which causes sulfidation, so that it is not easily discolored. In addition, the paper made of doc pulp has a certain space between the fibers to absorb or release moisture according to the surrounding humidity to control the humidity and has an excellent soundproofing effect. On the other hand, citrus gourds produce about 60,000 tons (2004) per year on Jeju Island, but only 30% of them are used as herbs, fertilizers and feeds, and the remainder is dumped on the ocean, becoming a source of marine pollution. Since marine dumping of land waste is prohibited, new treatment is needed. The pulp component obtained by cooking these citrus fruit cakes gives aesthetics with the appearance of a subtle citrus flavor and a yellow color, and has functions such as antibacterial, antifungal and deodorizing properties. Therefore, the tile of the present invention including the docpulp and citrus foil pulp exhibits various functionalities and at the same time has an environmentally friendly feature.

The manufacturing process of the tile according to the present invention includes a citrus peeling step, a pulp mixing step, a wetland forming step, a drying step, and may add a coating step as necessary.

In the citrus peeling step, citrus peels are prepared, raw materials are removed, washed with water, and then added to sodium hydroxide to prepare a citrus peel. Citrus gourd paste contains citrus gourd pulp, and also contains ingredients such as wax and essential oils contained in citrus gourd.

In the pulp mixing step, the pulp mixture is prepared by mixing citrus sautumate, Doc pulp and additives. At this time, in order to improve the physical properties and workability of the tile, additives such as flame retardant, desiccant, mental reinforcing agent, antifoaming agent and the like can be mixed. It can also mix further within the range which does not reduce the characteristic of a pulp.

In the wetland formation step, the pulp mixture in contaminated state is put in a molding mold and dehydrated to form a wetland. When forming wetlands, a method similar to the conventional paper manufacturing method is used, but natural dehydration or mechanical dehydration can be freely selected.

In the drying step, the wetlands are dried to produce tiles.

In addition, a coating step may be added in order to impart desirable physical properties such as flame retardancy, waterproofness, or add aesthetics as necessary.

In the coating step, a coating agent containing a component selected from flame retardants, waterproofing agents, varnishes, pigments and the like is applied to the tiles, and then dried again to complete the tiles.

Since the tile according to the present invention is composed mainly of natural pulp prepared from citrus bak and doc, the content of volatile organic compounds is lower than that of conventional tiles, so that there is no risk of contaminating indoor air. It is small in amount and has eco-friendly features. In addition, the tile according to the present invention exhibits antimicrobial and antifungal properties and is excellent in deodorizing power and emits far infrared rays and emits negative ions. Therefore, the tile has an effect of creating a healthy indoor environment and preventing sick house syndrome.

The manufacturing process of the tile according to the present invention includes a citrus peeling step, a pulp mixing step, a wetland formation step, a drying step, and may further include an application step as necessary, and the detailed manufacturing method will be described in detail below step by step. do.

In the citrus peeling step, citrus peels are prepared, raw materials are removed, washed with water, and then added to sodium hydroxide to prepare a citrus peel. At this time, if the mixing amount of water is too high or too low, the workability is poor during wetland formation. Therefore, it is preferable to mix 100-200 parts by weight of water with respect to 100 parts by weight of citrus fruit, and if the amount of addition of sodium hydroxide is too small or the boiling time is too short, cooking If the addition amount of sodium hydroxide is too high or the boiling time is too long, the fiber may be damaged and the strength and yield of the pulp may be reduced, so that 0.1 to 1 parts by weight of sodium hydroxide is mixed with 100 parts by weight of citrus gourd. It is preferable to cook for ˜50 minutes.

In the pulp mixing step, the pulp mixture is prepared by mixing citrus sautumate, Doc pulp and additives. The duck pulp is used as a conventional paper pulp used in the manufacture of Korean paper, but mixing too small amount compared to citrus gourd decreases the strength and mixing too much amount decreases the effect of adding citrus fruit. It is preferable to contain 5 to 200 parts by weight of dried pulps with respect to 100 parts by weight of cooked matter.

In addition, it is also possible to further mix wood pulp, in which case it is possible to relatively reduce the cost, especially when using the paper pulp recycled wood pulp can significantly reduce the cost. If the amount of wood pulp is too small, there is no additive effect, and if too much, the strength may be relatively low. Therefore, it is preferable to include 1 to 50 parts by weight based on the dry state with respect to 100 parts by weight of citrus peel.

On the other hand, to enable the tile to exhibit more desirable physical properties or to further mix the additives for the convenience of the work process, the additives consisting of one or more components selected from flame retardants, desiccants, strength enhancers, antifoaming agents, If the mixing amount is too small, there is no effect of the addition, if too much, the physical properties of the tile may be degraded or it may not be good in terms of environmental friendliness, so mix 0.5 to 5 parts by weight of the additive with respect to 100 parts by weight of citrus peel.

In the wetland formation step, the pulp mixture in contaminated state is put in a molding mold and dehydrated to form a wetland. At this time, the molding frame is a shape in which the bottom or side can drain water as the foot, and uses a frame of size and height that meets the standard of the tile to be manufactured. Rapid dewatering can also be used.

In the drying stage, the wetland is dried to produce tiles, and when drying, natural drying may be used, or drying may be performed more quickly using a dryer.

In addition, a coating step may be added in order to impart desirable physical properties such as flame retardancy, waterproofness, or add aesthetics as necessary.

In the coating step, a coating agent consisting of one or more components selected from flame retardants, waterproofing agents, varnishes, pigments, etc. is applied to the tiles, and then dried again to complete the tiles. At this time, if the amount of the coating agent is too small, the coating effect is inferior, and if too much may cause the functionality of the tile itself, it is preferable to apply 0.5 to 10 parts by weight of the coating agent to 100 parts by weight of citrus peel. Do.
