In addition, a detailed description of a mixer, a kneader, a dryer or a grinder, which is a mechanical device used in the manufacturing process of the melamine synthetic resin, will be omitted, and hereinafter, the first mixing process, the cooling process, the second mixing process, and the third mixing process. And the fourth mixing process, kneading process, drying process, and grinding process will be described.
또한, 본원발명에서 청구되는 상기 중량부는 멜라민 합성수지 100중량부에 대한 함량비를 의미함을 첨언한다. In addition, it is noted that the weight part claimed in the present invention means a content ratio with respect to 100 parts by weight of melamine synthetic resin.
[제1혼합공정] [First mixing process]
상기 제1혼합공정은, 상기 멜라민을 포함한 혼합물의 물성을 변성하여 pH를 10 내지 11로 맞추는 공정으로서, 상기 혼합기에 장입된 혼합물을 가열하여 알킬화함으로써 변성 멜라민 합성수지를 얻는 공정이다.The first mixing step is a step of modifying the physical properties of the mixture containing melamine to adjust the pH to 10 to 11, and is a step of obtaining a modified melamine synthetic resin by alkylating by heating the mixture charged in the mixer.
상기 제1혼합공정은, 포르말린 46.5∼60중량부 - 에탄올 11.2∼20중량부 - 헥사메틸렌테드라민 0.001∼0.11중량부 - 트리에틸렌글리콜 0.42∼0.61중량부 - 가성소다 1.01∼1.95중량부를 교반하여 혼합한 후, 멜라민 23∼35중량부 및 소포제 0.05∼0.15중량부를 첨가하고 교반하여 혼합한다.In the first mixing step, formalin 46.5-60 parts by weight-ethanol 11.2-20 parts by weight-hexamethylenetetramine 0.001-0.11 parts by weight-triethylene glycol 0.42-0.61 parts by weight-caustic soda 1.01-1.95 parts by weight and mixing Then, 23 to 35 parts by weight of melamine and 0.05 to 0.15 parts by weight of an antifoaming agent were added and stirred to mix.
상기 제1혼합공정에서는 상기 포르말린이나 멜라민을 포함한 혼합물을 75∼100℃의 온도로 50∼90분 동안 반응시킴이 바람직하다.In the first mixing step, it is preferable to react the mixture containing formalin or melamine at a temperature of 75 to 100 ° C for 50 to 90 minutes.
상기 포르말린과 상기 멜라민의 함량은 이후에 설명하게 되는 천연성분의 함량에 따라 달라지지만, 제1혼합공정에서는 상기 포르말린 46.5∼60중량부를 첨가하였고 상기 멜라민 23∼35중량부를 첨가하였다.The content of the formalin and the melamine varies depending on the content of natural ingredients to be described later, but in the first mixing process, 46.5-60 parts by weight of the formalin was added and 23-35 parts by weight of the melamine was added.
상기 포르말린의 함량은, 상기 포르말린과 상기 멜라민의 몰비(1.4 ∼2.1)에 따라 달라질 수 있지만, 상기 포르말린이 46.L5 중량부 미만인 경우 상기 멜라민의 미반응이 발생하고, 상기 포르말린이 60중량부 이상인 경우 상기 포르말린에서 환경호르몬이 발생할 우려가 있다.The content of the formalin may vary depending on the molar ratio of the formalin and the melamine (1.4 to 2.1), but when the formalin is less than 46.L5 parts by weight, unreacted melamine occurs, and the formalin is 60 parts by weight or more In this case, there is a risk that environmental hormones are generated in the formalin.
상기 멜라민의 함량이 23중량부 미만이면 내마모성이 저하되고 외관미를 향상하기가 어려우며, 상기 멜라민의 함량이 35중량부를 초과하면 강도가 지나치게 높아져 가공성 및 취급성이 떨어진다.If the content of the melamine is less than 23 parts by weight, the wear resistance is lowered and it is difficult to improve the appearance, and when the content of the melamine exceeds 35 parts by weight, the strength is too high, resulting in poor processability and handling.
상기 제1혼합공정에서의 가열온도 및 가열시간을 75∼100℃ 및 50∼90분으로 한정한 이유는 상기 에탄올 등의 급격한 증발을 억제하고 상기 포르말린이나 상기 멜라민 등과의 반응성을 향상하기 위한 것이다.The reason for limiting the heating temperature and the heating time in the first mixing step to 75 to 100 ° C and 50 to 90 minutes is to suppress rapid evaporation of the ethanol and the like and to improve the reactivity with the formalin or the melamine.
상기 에탄올과 상기 가성소다는 상기 멜라민 합성수지의 pH를 조절하는 성분으로서 상기 에탄올의 경우 11.2∼20중량부를 첨가하였고, 특히 상기 에탄올과 헥사메틸렌테드라민과 트리에틸렌글리콜과 가성소다는 상기 멜라민과의 반응과정에서 촉매제로서 기능하므로 미량을 첨가하였다.The ethanol and the caustic soda are components to adjust the pH of the melamine synthetic resin, and in the case of the ethanol, 11.2 to 20 parts by weight was added. In particular, the reaction of the ethanol with hexamethylenetetramine, triethylene glycol and caustic soda with the melamine As a catalyst in the process, a small amount was added.
또한, 상기 소포제는 상기 멜라민 합성수지의 제조과정에서 거품형태로 이물질을 제거하는 성분으로서, 상기 멜라민 합성수지 100중량부에 대해 0.05∼0.15중량부를 첨가하여 이물질의 잔존량을 최소화하였다.In addition, the anti-foaming agent is a component that removes foreign substances in the form of bubbles during the manufacturing process of the melamine synthetic resin, by adding 0.05 to 0.15 parts by weight to 100 parts by weight of the melamine synthetic resin to minimize the residual amount of foreign matter.
[냉각공정][Cooling process]
상기 냉각공정은 상기 제1혼합공정에서 생성되는 혼합물을 실온보다 약간 높은 온도로 냉각하여 상기 혼합물을 안정화시키는 공정으로서, 상기 혼합물의 냉각온도는 45∼59℃가 바람직하지만, 이에 한정하지는 않는다.The cooling process is a process of stabilizing the mixture by cooling the mixture produced in the first mixing process to a temperature slightly higher than room temperature, and the cooling temperature of the mixture is preferably 45 to 59 ° C, but is not limited thereto.
[제2혼합공정][Second mixing process]
상기 제2혼합공정은, 상기 멜라민을 포함한 혼합물의 물성을 변성하여 pH를 9 이하로 낮추는 공정으로서, 상기 혼합기에 장입된 혼합물을 가열하여 알킬화함으로써 변성 멜라민 합성수지를 얻는 공정이다.The second mixing step is a step of modifying the physical properties of the mixture containing melamine to lower the pH to 9 or less, and is a step of obtaining a modified melamine synthetic resin by alkylating by heating the mixture loaded in the mixer.
상기 제2혼합공정은, 멜라민 28∼40중량부 - 포르말린 27∼40중량부 - 헥사메틸렌테드라민 0.17∼1.1중량부 - 개미산 0.033∼0.085중량부 - 혼합제 0.17∼1.1 중량부 - 트리에틸렌글리콜 0.13∼0.37중량부를 넣고 교반하여 혼합한다.The second mixing process, 28-40 parts by weight of melamine-27-40 parts by weight of formalin-0.17-1.1 parts by weight of hexamethylenetetramine-0.033-0.085 parts by weight of formic acid-0.17-1.1 parts by weight of mixing agent-0.13-triethylene glycol Add 0.37 parts by weight and stir to mix.
상기 제2혼합공정에서는 상기 포르말린이나 멜라민을 포함한 혼합물을 80∼100℃의 온도로 50∼80분간 반응시킴이 바람직하다.In the second mixing step, it is preferable to react the mixture containing formalin or melamine at a temperature of 80 to 100 ° C for 50 to 80 minutes.
상기 포르말린과 상기 멜라민의 함량은 이후에 설명하게 되는 천연성분의 함량에 따라 달라지지만, 제2혼합공정에서는 상기 멜라민 및 상기 포르말린은 각각 28∼40중량부 및 27∼40중량부를 첨가하였다.The content of the formalin and the melamine varies depending on the content of natural ingredients to be described later, but in the second mixing process, the melamine and the formalin added 28 to 40 parts by weight and 27 to 40 parts by weight, respectively.
상기 멜라민과 상기 포르말린의 함량비는 상기 제1혼합공정과 같은 이유의 함량비를 갖으므로 이에 대한 설명은 생략한다.The content ratio of the melamine and the formalin has a content ratio for the same reason as the first mixing process, so a description thereof will be omitted.
상기 헥사메틸렌테드라민과 상기 개미산과 상기 트리에틸렌글리콜은 상기 멜라민 및 포르말린의 촉매제의 기능을 수행하며, 상기 개미산은 상기 멜라민 합성수지의 pH를 조절하므로 0.033∼0.085 중량부를 첨가하였고, 상기 헥사메틸렌테드라민과 상기 트리에틸렌글리콜를 미량 첨가하여 촉매재의 기능을 부여하였다.The hexamethylenetedramin, the formic acid and the triethylene glycol function as a catalyst for the melamine and formalin, and the formic acid adjusts the pH of the melamine synthetic resin, so 0.033 to 0.085 parts by weight was added, and the hexamethylenetedramin And the triethylene glycol was added in a small amount to impart the function of the catalyst material.
상기 제2혼합공정에서 상기 멜라민 합성수지의 결합력을 증대하기 위한 수단으로서 상기 혼합제 0.17∼1.1중량부를 첨가하였다.In the second mixing step, 0.17 to 1.1 parts by weight of the mixing agent was added as a means for increasing the bonding strength of the melamine synthetic resin.
상기 제2혼합공정에서의 가열온도 및 가열시간을 80∼100℃ 및 50∼80분으로 한정한 이유는 상기 헥사메틸렌테드라민 등의 급격한 증발을 억제하고 상기 포르말린이나 상기 멜라민 등과의 반응성을 향상하기 위한 것이다.The reason for limiting the heating temperature and the heating time in the second mixing process to 80 to 100 ° C and 50 to 80 minutes is to suppress rapid evaporation of the hexamethylenetetramine and to improve reactivity with the formalin or the melamine. It is for.
[제3혼합공정][3rd mixing process]
상기 제3혼합공정은 상기 제2혼합공정에서 생성된 혼합물의 유동성을 확보하는 공정으로서, 상기 멜라민 합성수지 100중량부에 대하여, 에탄올 10∼30중량부 - 순수 7∼70중량부를 첨가하고 60분 이내로 유지함으로써 상기 혼합물을 액상상태로 유지시킴은 물론 안정화시킨다.The third mixing process is a process for ensuring the fluidity of the mixture produced in the second mixing process, and 10 to 30 parts by weight of ethanol-7 to 70 parts by weight of pure water and within 60 minutes of 100 parts by weight of the melamine synthetic resin By holding it, the mixture is kept in a liquid state and is stabilized as well.
상기 에탄올 및 상기 순수는 이후에 설명하는 건조공정에서 증발하는 특성을 갖고 있으므로, 제3혼합공정에서는 각각 10∼30중량부 및 7∼70중량부를 첨가하였으나 이에 한정하지는 않는다.Since the ethanol and the pure water have evaporation characteristics in a drying process described later, 10 to 30 parts by weight and 7 to 70 parts by weight were added in the third mixing process, respectively, but are not limited thereto.
상기 제3혼합공정에서의 가열온도 및 가열시간을 80∼100℃ 및 60분 이내로 한정한 이유는 상기 에탄올이나 상기 순수의 급격한 증발을 억제하고 상기 제2혼합공정에서 용해되지 않은 조성물의 반응성을 향상하기 위한 것이다.The reason for limiting the heating temperature and heating time in the third mixing process to within 80 to 100 ° C and 60 minutes is to suppress the rapid evaporation of the ethanol or the pure water and improve the reactivity of the composition not dissolved in the second mixing process. It is to do.
[제4혼합공정][4th mixing process]
상기 제4혼합공정은 상기 제3혼합공정에서 유동성이 증대된 혼합물을 결합력을 증대하는 공정으로서, 상기 멜라민 합성수지 100중량부에 대하여, 실리콘 0.5∼3중량부 - 혼합재 2.1∼10중량부를 첨가하였다.The fourth mixing step is a step of increasing the bonding strength of the mixture having increased fluidity in the third mixing step, and 0.5 to 3 parts by weight of silicone-2.1 to 10 parts by weight of the mixture was added to 100 parts by weight of the melamine synthetic resin.
상기 제4혼합공정에서는 상기 실리콘이나 혼합제를 포함한 혼합물을 80∼100℃의 온도로 40∼60분간 반응시킨다.In the fourth mixing step, the mixture containing the silicone or the mixing agent is reacted at a temperature of 80 to 100 ° C for 40 to 60 minutes.
상기 혼합재는 성형제품의 열전도도를 높여 성형과정에서의 이형성을 향상하는 특징이 있으므로 2.1∼10중량부를 첨가하였고, 상기 실리콘은 상기 혼합물의 결합력을 증대하는 특징이 있으므로 0.5∼3중량부를 첨가하였다.The mixed material has a feature of increasing the thermal conductivity of a molded product to improve the releasability in the molding process, so that 2.1 to 10 parts by weight was added, and the silicone was added with 0.5 to 3 parts by weight because of the characteristic of increasing the bonding strength of the mixture.
상기 혼합재를 2.1 중량부 미만으로 첨가하는 경우 성형제품의 이형성이 저하되어 손상이 있으며, 상기 혼합재를 10 중량부 이상으로 첨거하는 경우 성형제품이 변형될 우려가 있으므로, 2.1∼10중량부로 한정하였다.When the mixture was added in an amount of less than 2.1 parts by weight, the molded product was deformed and damaged, and when the mixture was added in an amount of 10 parts by weight or more, the molded product could be deformed, so it was limited to 2.1 to 10 parts by weight.
상기 실리콘을 0.5 중량부 미만으로 첨가하는 경우 상기 혼합물의 결합력을 증대하기 미흡하였고, 상기 실리콘을 3.0 중량부 이상으로 첨가하는 경우 결합력이 증대되어 성형제품이 변형될 우려가 있었다.When the silicone was added in an amount of less than 0.5 parts by weight, it was insufficient to increase the bonding strength of the mixture, and when the silicone was added in an amount of 3.0 parts by weight or more, there was a fear that the molded product was deformed due to an increase in the bonding strength.
상기 제4혼합공정에서의 가열온도 및 가열시간을 80∼100℃ 및 40∼60분으로 한정한 이유는 상기 실리콘이나 상기 혼합제가 골고루 용해되는 온도 및 시간을 고려한 것으로서 이에 한정하지는 않는다.The reason for limiting the heating temperature and the heating time in the fourth mixing process to 80 to 100 ° C and 40 to 60 minutes is to consider the temperature and time at which the silicone or the mixing agent is evenly dissolved, but is not limited thereto.
[혼련공정][Kneading process]
먼저, 상기 혼련공정은 상기 제4혼합공정에서 생성된 혼합물에 상기 천연성분을 첨가하고 교반하여 골고루 분포시키는 공정으로서, 상기 멜라민 합성수지 100중량부에 대해, 천연성분 50∼450중량부를 첨가하였다. First, the kneading process is a process of adding the natural ingredients to the mixture produced in the fourth mixing process and distributing them evenly, and with respect to 100 parts by weight of the melamine synthetic resin, 50 to 450 parts by weight of natural ingredients are added.
상기 천연성분의 함유량이 50중량부 미만인 경우 상기 성형제품에서 발생하는 유해성분의 제거가 어렵고, 상기 천연성분의 함유량이 450중량부 이상인 상기 성형제품의 결합력이 저하되므로, 상기 천연성분의 함유량으로서 상기 멜라민 합성수지 100중량부에 대해 50∼450중량부로 한정하였다. When the content of the natural component is less than 50 parts by weight, it is difficult to remove harmful components generated in the molded product, and the content of the natural component is lower than 450 parts by weight of the molded product. It was limited to 50 to 450 parts by weight relative to 100 parts by weight of the melamine synthetic resin.
상기 천연성분은 상기 멜라민 합성수지의 용도에 따라 다양한 함량으로 첨가할 수 있으나, 상기 혼련공정에서는 50 ∼450중량부로 한정하였으며, 상기 천연성분의 종류에 따라 상기 혼련시간은 달라질 수 있다.The natural ingredients may be added in various contents depending on the use of the melamine synthetic resin, but in the kneading process was limited to 50 to 450 parts by weight, and the kneading time may vary depending on the type of the natural ingredients.
상기 혼련공정에서는 상기 천연성분을 포함한 혼합물을 80∼100℃의 온도로 60∼120분간 혼련함이 바람직하며, 상기 가열온도 및 가열시간은 상기 천연성분의 혼련량을 고려한 것으로 이에 한정하지는 않는다.In the kneading step, it is preferable to knead the mixture containing the natural component at a temperature of 80 to 100 ° C. for 60 to 120 minutes, and the heating temperature and heating time are not limited to this considering the amount of kneading of the natural component.
상기 천연성분은 옥파우더, 펄프, 견운모, 백운모 중 적어도 어느 하나 또는 이들을 혼합물이 바람직하지만, 그 밖에도 자수정이나 맥반석이나 황토 등을 적용하더라도 본원의 기술범주에 포함됨은 당연하다. The natural component is preferably at least one of ox powder, pulp, silk, and muscovite, or a mixture thereof, but it is natural that it is included in the technical category of the present application even if amethyst, mackban, or ocher is applied.
[건조공정][Drying process]
상기 건조공정은 상기 혼련공정에서 생성된 혼련물을 100℃ 이하의 온도에서 60분 이내로 가열하여 수분으로 제거하는 공정으로서, 상기 혼합물에 포함된 수분이나 에탄올 등의 함량을 최소화하는 공정을 의미한다.The drying process is a process of heating the kneaded product produced in the kneading process at a temperature of 100 ° C. or less within 60 minutes to remove moisture, and means a process of minimizing the content of water or ethanol contained in the mixture.
상기 건조공정에서 건조 온도가 높거나 건조 시간이 길어지면 수지의 유동성에 악영향을 끼칠 우려가 있고, 상기 건조 온도가 낮거나 시간이 짧으면 수지의 경화 속도가 늦어져 밀도가 저하될 우려가 있다. When the drying temperature is high or the drying time is long in the drying process, there is a fear of adversely affecting the fluidity of the resin. If the drying temperature is low or the time is short, the curing speed of the resin is slowed and the density may decrease.
[분쇄공정][Crushing process]
상기 분쇄공정은 상기 건조공정에서 건조된 건조물을 상기 분쇄기에 장입한 상태에서 200∼400 메쉬로 분쇄하여 파우더로 제조하는 공정이다. The crushing process is a process of pulverizing the dried material dried in the drying process into 200 to 400 mesh in a state loaded in the pulverizer to produce powder.
[성형공정][Molding process]
상기 성형공정은 상기 분쇄공정이 완료된 파우더를 프레스나 성형기로 성형하여 성형제품으로 제조하는 공정으로서, 상기 성형제품은 환경호르몬의 차단효과가 있으므로 인간이 거주하는 실내제품으로 적용한다.The molding process is a process in which the pulverized process is completed by molding a powder with a press or a molding machine to produce a molded product. Since the molded product has a blocking effect of environmental hormones, it is applied as an indoor product inhabited by humans.
상기 성형제품은 인조대리석과 같은 건축자재, 씽크대나 욕조와 같은 부엌가구, 장롱을 포함한 가구제품, 타일이나 천정재나 바닥재와 같은 실내장식물, 건축물의 내장재, 의료기 등의 실내제품에 적용한다.The molded products are applied to construction materials such as artificial marble, kitchen furniture such as sinks or bathtubs, furniture products including wardrobes, interior decorations such as tiles and ceiling materials or flooring materials, interior materials of buildings, and indoor products such as medical devices.

(3) 제3혼합공정(3) Third mixing process
상기 혼합기에, 에탄올 20중량부와 순수 50중량부를 첨가하고 30분 동안 유지한 결과, 상기 천연성분을 첨가하기에 적합한 액상상태로 유지되어, 상기 혼합물이 유동성이 확보되었음을 알 수 있었다. As a result of adding to the mixer, 20 parts by weight of ethanol and 50 parts by weight of pure water and holding for 30 minutes, it was found that the mixture was maintained in a liquid state suitable for adding the natural ingredients, and the fluidity was ensured.

To the mixture produced in the third mixing process, 2.0 parts by weight of silicone and 6 parts by weight of the mixture were added and reacted for 50 minutes. As a result, the silicone or the mixture was dissolved in the mixture and could not be visually confirmed.
(5) 혼련공정(5) Kneading process
상기 혼합기에, 상기 천연성분인 상기 옥파우더 50중량부와 상기 펄프 10중량부와 상기 견운모 10중량부를 첨가하고 90분 동안 교반한 결과, 상기 혼합물 중에 천연성분이 골고루 분포하고 있음을 확인할 수 있었다.As a result of adding to the mixer, 50 parts by weight of the natural ingredient, ox powder, 10 parts by weight of the pulp, and 10 parts by weight of the silkworm, and stirring for 90 minutes, it was confirmed that the natural ingredients were evenly distributed in the mixture.

As a result of molding the pulverized product produced in the crushing process into a panel-shaped building material using a press, it was confirmed that natural components such as the ox powder were evenly kneaded on the outer surface of the building material.
(8) 소결론(8) Sintering theory
상기 성형공정에서 성형된 건축자재의 외표면에 상기 옥파우더와 같은 천연성분이 골고루 혼합되어 있고, 이로 인해 상기 천연성분의 자체특성에 의해 환경호르몬을 포함한 유해물질의 분해량이 증대될 것으로 예측된다.Natural components such as the ox powder are evenly mixed on the outer surface of the building material molded in the molding process, and accordingly, it is expected that the amount of decomposition of harmful substances including environmental hormones will increase due to the nature of the natural components.
