Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an organic compound,

More particularly, the present invention relates to a method for manufacturing organic materials, which is excellent in process efficiency and cost-saving compared to a conventional method for producing organic materials using molds.

Organic is a brass product that was used by the court and chapters since the Joseon Dynasty. It has strong durability, antibacterial and anti-bacterial properties, and it has been used for a wide range of applications such as tableware, baskets and sidewalks.

On the other hand, the atmospheric concentration of the gas generated from the burning has increased sharply due to the rapid increase in the use of fossil fuels such as briquettes and petroleum, and the rust on the surface of organic products is easily generated by these gases, . In addition, due to the development of technology, a variety of functional new materials have been developed to replace organic materials, and the demand for organic materials has rapidly decreased.

However, recently, attention has been focused on organic products, which focus on the pale color of the organic products and the inherent functionality of the organic products, thereby improving the aforementioned problems.

Generally, such an organic product is manufactured by pouring and dissolving organic matter dissolved in a mold, and then kneading the product to form a product. There has been a problem in that a separate mold has to be manufactured and a process of knocking for a long time and a process for producing light have been required, so that mass production is impossible and the economic efficiency such as a long time is deteriorated. In addition, since it is not a mechanization method, the uniformity of the product is lowered, resulting in a high defect rate.

In addition, in the case of organic waste, a large amount of voids are generated in the organic product due to the bubbles generated in the manufacturing process, resulting in a decrease in durability and oxidation due to the internal gas in the void.

Accordingly, various studies have been conducted to reduce the production time and mass production without deteriorating the function of the organic product.

Hereinafter, the present invention will be described in more detail.

Organic manufacturing method

≪ Production step of the melt &

First, tin and copper, which are raw materials for organic production, are prepared.

Thereafter, the tin and copper are mixed and melted at a predetermined temperature to prepare a melt.

In the present invention, the mixing ratio (weight ratio) of tin and copper is not particularly limited and may be selected within an appropriate range according to the required physical properties of the organic product. For example 20 to 40 wt.% Of tin and 60 to 80 wt.% Of copper, more preferably 20 to 30 wt.% Of tin and 70 to 80 wt.% Of copper. When mixed within the above range, the produced organic product may exhibit excellent antibacterial and thermostability.

In the present invention, the temperature at which the melting process is carried out is not particularly limited, but may be appropriately selected within a range in which the mixture can be completely melted. Specifically, it can be appropriately selected according to the intrinsic melting point of the mixed tin and copper and the degree of the appropriate melting point change according to the mixing ratio thereof, and can be performed at a temperature of, for example, 1000 to 1500 ° C. When the melt is melted in the above-mentioned temperature range, the homogeneity of the melt is excellent and the appropriate viscosity is exhibited, so that the ingot manufacturing process described later can be easily performed.

≪ Production step of ingot>

Next, the melt is produced as a sheet-like ingot.

The method for producing the ingot in the form of a plate is not particularly limited. For example, the ingot may be produced by pouring the melt into a flat mold and then solidifying. In detail, a predetermined groove The ingot can be separated from the mold through the groove in the rim and the ingot can be produced in a uniform size.

In the present invention, the temperature at which the plate-like ingot is hardened is not particularly limited. However, when the plate is used, it can be carried out at a temperature at which separation from the frame is easy without deformation of the ingot. For example, Lt; RTI ID = 0.0 > of < / RTI >

Thereafter, a step of rolling the plate-like ingot may be further performed.

In order to enable the mass production of organic products and to reduce the defect rate of the product, it is required that the produced plate-shaped ingot has the same thickness. The tin can be easily broken at a temperature of 550 ° C or higher, It is most important to adjust the temperature to an appropriate range.

In the present invention, it is possible to perform the rolling process by heating the plate-like ingot so that the temperature of the ingot can be maintained at 500 to 550 ° C, thereby making it possible to produce the plate-like ingot of uniform thickness without changing the shape.

Further, the bubbles generated in the melt forming process and the like are removed through the step of rolling the ingot so as to satisfy the above-mentioned temperature range, whereby the voids of the final organic product can be reduced and the durability can be remarkably improved. Further, It is possible to reduce the occurrence of oxidation of the interior of the organic product.

On the other hand, when the temperature of the ingot is less than 500 캜 in the rolling process, a part of the ingot hardens and cracking or breakage may occur during the rolling process. When the temperature exceeds 550 캜, the viscosity excessively increases and molding may be difficult.

In the present invention, the method of the rolling process is not particularly limited. However, it is possible to produce a uniform thickness required by using rollers. In the case of simply controlling the temperature of the support plate in the rolling process, The forming ability of the ingot may deteriorate. In the present invention, it is possible to heat the rollers, the supporting plate and the roller mold of the machine so that the plate-shaped ingot itself can be maintained at 500 to 550 ° C during the process.

In the present invention, the temperature control of the rolling process can be performed by attaching a temperature sensor inside the apparatus in which the rolling process is performed to detect the temperature change of the ingot, and applying heat using a torch lamp, a comb bear, However, it is not particularly limited.

When a plate-like ingot having a predetermined thickness is produced through the above-described process, it is possible to carry out a process of cutting the ingot into a predetermined size to meet the size of the required product. In this case, the ingot can be maintained at a temperature range of 500 to 550 ° C. .

<Hydraulic Forming Step>

The plate-shaped ingot having the same size and thickness manufactured according to the above-described method is hydraulically molded into the shape of the desired product.

Conventionally, in a process for producing a crude organic product, a repeated kneading process is performed in order to obtain a desired product shape. In this process, since the temperature of the ingot continuously changes, problems such as a large number of micro cracks . In addition, even when only the temperature in the process is controlled, micro-cracks may occur in the organic material due to the temperature of the apparatus used in the forming process, thereby lowering the durability of the product and preventing the quality of the product from being maintained uniformly There was a problem.

The hydraulic forming step according to the present invention is performed by heating the plate-shaped ingot so as to maintain the temperature at 500 to 550 ° C, thereby making it possible to produce an organic product having excellent durability with uniform quality, and to mass-produce the product.

When the ingot satisfies the above temperature in the hydraulic forming step, it is possible to prevent occurrence of cracks or fractures that may occur in the step of applying pressure.

In the present invention, the hydraulic forming process may be performed by applying pressure to the plate-like ingot by using a mold suitable for the desired product shape. For example, when the plate-like ingot itself is maintained at a temperature of 500 to 550 ° C A step of inserting a plate-like ingot between the upper mold and the lower mold which are respectively heated and then pressurizing the plate.

Specifically, the hydraulic forming process may be performed using an apparatus having a pair of male and female upper and lower molds. After placing the plate-shaped ingot on the lower mold, pressure is applied to the ingot by the upper mold Thereby making it possible to produce an organic material having a desired shape. A predetermined spring and an adjusting plate may be disposed on the inner lower portion of the lower mold, thereby buffering instantaneous pressure applied by the upper mold, thereby making it possible to produce a desired shape of the organic material.

In the present invention, the hydraulic forming process can be performed by applying lubricating oil to the upper portion of the plate-like ingot, and then pressing the upper portion of the ingot, thereby reducing the friction between the upper die and the ingot, do.

In the present invention, the kind of the lubricating oil is not particularly limited, and for example, Teflon oil can be used.

The method of manufacturing an organic material according to the present invention may further include a step of polishing after the hydraulic molding step when gloss is required depending on the product. The method of performing the polishing process is not particularly limited and can be applied without any particular limitations as long as it is a method that is usually performed in the art.

The organic products manufactured through the above process can be mass-produced into organic products of the same type using a CNC automatic lathe.

The method for producing an organic material according to the present invention may further include a step of cooling at 10 to 20 ° C after the hydraulic forming step. The shape of the organic material is hardened through the cooling process,
