Description
본 발명은 분체도료의 제조공정에서 생성되는 부산물을 수집하여 불순물을 제거한 후 재사용하도록 한 분체도료의 재처리방법 및 장치에 관한 것이다.The present invention relates to a powder coating reprocessing method and apparatus for collecting by-products generated in the manufacturing process of powder coating to remove impurities and reuse them.
일반적으로 분체도료의 조성물은 수지, 용제, 안료, 첨가제로 구성되어 있고, 분체도료는, 그 구성물 중 용제가 함유 되어있지 않은 100% 고형분인 수지, 안료, 첨가제를 배합하여 균일하게 용융 분산시킨 분말분체도료로써, 일반적인 방법 (붓, 로라, 일반 스프레이 등)으로 도장을 하지 않고, 정전분체도장이나 유동침지도장을 하여 도막을 형성합니다.Generally, the powder coating composition is composed of a resin, a solvent, a pigment, and an additive, and the powder coating is a powder obtained by uniformly melting and dispersing a resin, a pigment, and an additive, which is a 100% solids containing no solvent. As a powder coating, it is not coated by a general method (brush, roller, general spray, etc.), but an electrostatic powder coating or a fluid immersion coating is formed to form a coating film.
이러한 분체도료의 장점으로는, 경제성이 높고, 회수분체도료의 사용이 가능하며, 폐기물이 없기에 폐기처리비용이 절감되고, 점착성이 없어 청소가 용이하다.Advantages of such powder coatings are high economical efficiency, recovery powder coatings can be used, waste disposal costs are reduced because there is no waste, and adhesiveness is easy to clean.
또한 용제에 의한 중독, 화재나 폭발 위험성이 없고, 대기오염이나 수질오염등 환경공해가 매우 적으며, 도장기술의 편리성으로 1회 도장으로 두꺼운 도막을 얻을 수 있고, 도장공정을 단축하여 생산성이 향상된다.In addition, there is no risk of poisoning, fire or explosion by solvents, and there is little environmental pollution such as air pollution or water pollution.With the convenience of painting technology, a thick coating film can be obtained by one coating. Is improved.
단점으로는 분체도료 전용도장기기 필요하고, 작업라인에서 색상의 교체가 곤란하며, 박막도장(40㎛이하)이 어렵고, 경화온도가 높으며, 도막의 평활도, 조색의 정밀도가 액체 분체도료보다 떨어진다.Disadvantages are the need for special coating equipment for powder coating, difficult to change color in the work line, difficult for thin film coating (less than 40㎛), high curing temperature, smoothness of paint and precision of color coating are inferior to liquid powder coating.
일반적인 분체도료의 제조공정은 도 3에 도시된 것과 같이, 수지와 안료 및 휠러를 공급하는 투입단계(S1)와, 이를 섞는 혼합단계(S2)와, 혼합후 가열하는 용융압출단계(S3)와, 용융압출된 분체도료를 냉각하는 냉각단계(S4)와, 이 냉각단계(S4)를 거친 후 미쇄하게 가루로 만드는 분쇄단계(S5)와, 이 분쇄단계(S5)를 거친 분체도료의 굵은 입자를 걸러내는 분리단계(S6)와, 이 분리단계(S6)를 거친 분체도료를 포장하는 포장단계(S7)로 이루어진다.As shown in FIG. 3, a general powder coating process includes a feeding step (S1) for supplying a resin, a pigment, and a wheeler, a mixing step (S2) for mixing the same, and a melt extrusion step (S3) for heating after mixing; Cooling step (S4) for cooling the melt-extruded powder coating, grinding step (S5) to make a fine powder after the cooling step (S4), and the coarse particles of the powder coating through this grinding step (S5) It consists of a separation step of filtering (S6), and a packaging step (S7) of packaging the powder coating through the separation step (S6).
이렇게 분체도료의 제조공정이 포장까지 완료되면 청소단계(S8)를 하게 됨은 물론이다.In this way, when the manufacturing process of the powder coating is completed to the packaging is a cleaning step (S8) of course.
상기와 같은 분체도료의 제조공정이 진행되는 동안 비산되는 분체도료를 집진기로 포집하거나 잔유물의 청소에 의해서 발생되는 폐분체도료를 포대에 수거한다.The powder coating, which is scattered during the process of manufacturing the powder coating as described above, is collected by a dust collector or the waste powder coating generated by cleaning the residue is collected on the bag.
이때 폐분체도료의 총중량을 100으로 보았을 때, 상기 용융압출단계(S3)에서 30%가 발생되고, 상기 냉각단계(S4)에서 10%가 발생되며, 상기 분쇄단계(S5)에서 15%, 상기 분리단계(S6)에서 30%, 상기 포장단계(S7)에서 5%가 발생되고, 마지막으로 청소단계(S8)에서 10%가 발생된다.At this time, when the total weight of the powder coating powder is 100, 30% is generated in the melt extrusion step (S3), 10% is generated in the cooling step (S4), 15% in the grinding step (S5), the 30% in the separation step (S6), 5% occurs in the packaging step (S7), and finally 10% occurs in the cleaning step (S8).
이렇게 수거된 폐분체도료는 흰색의 경우 액상으로 만들어 다른색과 조합하여 다른색상을 내는데 사용할 수 있으나, 색이 어두운 것이나 탁한색은 본래의 색을 내지 못해 지정장소에 매립하게 된다.The collected waste powder paint can be used to make a liquid in the case of white color and combine it with other colors, but the dark or turbid color can be buried in a designated place because it does not have the original color.
이렇게 매립되는 량은 전국적으로 년간 약 3,000톤에 이르고, 그 수치는 년간 11.2% 씩 증가하는 추세이며, 유해물질이 없는 분체도료의 사용을 권장하는 관계로 그 사용은 기하급수적으로 증가추세에 있다.The amount of landfill is about 3,000 tons per year nationwide, and the figure is increasing by 11.2% per year, and its use is increasing exponentially because it recommends the use of powder coating without harmful substances.
그러나 분체도료는 토양에서 분해가 되지 않아 지정된 매립장소에 매립해야 하므로 매립장소가 부족하게 되는 문제점이 있었다.However, because the powder coating is not decomposed in the soil, it has to be buried in a designated landfill place, there is a problem that the landfill site is insufficient.
본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 분체도료의 제조공정중에 발생된 폐분체도료를 수거하여 불순물을 제거한 후 아스콘의 제조에 사용되는 아스팔트와 일정비율로 섞어서 사용할 수 있도록 하므로서, 종래의 문제점을 해소함은 물론, 아스팔트제품의 품질을 향상시킬 수 있도록 한 분체도료의 재처리방법 및 장치를 제공함에 그 목적이 있다.The present invention has been made in view of the conventional problems as described above, by collecting the waste powder paint generated during the manufacturing process of the powder coating to remove impurities, so that it can be mixed with the asphalt used in the manufacture of ascone in a certain ratio. To solve the conventional problems, as well as to provide a method and apparatus for reprocessing powder coating to improve the quality of asphalt products.

한편 상기 분체도료의 재처리장치는, 저장된 폐분체도료(W)를 투입할 수 있도록 된 호퍼(11)와, 이 호퍼(11)의 위에 미세한 입자만이 통과되도록 그물형상으로 설치된 스크린(12)과, 상기 호터(11)의 하부에 설치되어 진동에 의해 상기 스크린(12)에 부어진 분체도료의 미세입자가 하부로 떨어지도록 된 진동기(14)를 포함한다.On the other hand, the powder coating reprocessing apparatus, the hopper (11) which can put the stored waste powder coating (W), and the screen 12 is installed in a net shape so that only the fine particles pass on the hopper (11) And a vibrator 14 installed at the lower portion of the hotter 11 so that the fine particles of the powder coating poured on the screen 12 by the vibration fall to the lower portion.
또한 상기 호퍼(11)의 하부로 떨어진 분체도료의 미세입자를 일측으로 이송하도록 설치된 이송스크류(15)와, 이 이송스크류(15)에 의해 이송된 분체도료를 승강시키는 버켓엘리베이터(16)와, 이 버켓엘리베이터(16)로 공급되는 분체도료에 포함된 미세입자등의 찌꺼기를 집진하는 집진기(17)가 상부에 설치된 저장싸이로(18)를 포함한다.In addition, the transfer screw 15 is installed to transfer the fine particles of the powder coating dropped to the lower side of the hopper 11, the bucket elevator 16 for elevating the powder coating transferred by the transfer screw 15, and The dust collector 17 which collects the fine particles etc. contained in the powder coating material supplied to this bucket elevator 16 includes the storage path 18 provided in the upper part.
여기서 상기 아스팔트와 폐분체도료는 중량비로 90:10 ~ 70:30로 혼합하여 사용하게 되면 아스팔트만을 사용하는 것과 비교하여 표1에 나타낸 것과 같이, 밀도(㎏/㎤), 마샬시험 공시체에 하중을 가하여 공시체가 파괴될 때의 하중인 안정도 (㎏), 다져진 역청 혼합물의 용적중 공극이 차지하는 용적을 백분율로 나타낸 공극률(%), 다져진 역청 혼합물의 골재 간극중 역청재가 차지하는 용적을 백분율로 나타낸 포화도(%) 및 후로우등의 성능이 향상된다.Here, when the asphalt and the powder coating powder are mixed in a weight ratio of 90:10 to 70:30, the density (kg / cm 3), and the load on the test specimens as shown in Table 1 are compared with those using only asphalt. Stability (kg), which is the load at the time of destruction of the specimen, the porosity (%) of the volume of the pore of the compacted bitumen mixture, %), And the performance of the flow is improved.
이때 아스팔트와 폐분체도료의 혼합되는 비율은 중량비로 85:15 즉, 15%로 혼합하였을 때, 그 성능이 가장 우수한 상태로 된다.At this time, the mixing ratio of the asphalt powder and the waste powder is 85:15 in weight ratio, that is, when mixed at 15%, the performance is the best state.
이렇게 제조된 아스콘이 품질향상되는 주원인은 폐분체도료에 함유되어 있는 레진(에폭시수지, 폴리에스텔수지)이 60% 함유하고 있어, 폐분체도료가 외부의 온도 120℃ 이상부터 레진의 분자가 망상형태를 유지하면서 열경화성 물질이 되어 소성변형 감소 및 안정도가 증가하는 것이다.The main reason for improved quality of Ascon is that 60% of the resin (epoxy resin, polyester resin) contained in the waste powder paint is contained. The thermosetting material is maintained while maintaining the plastic deformation and stability is increased.
상기와 같이 설명한 바에 의하면, 분체도료의 제조공정중에 발생된 폐분체도료를 수거하여 불순물을 제거한 후 아스콘의 제조에 사용되는 아스팔트와 일정비율로 섞어서 사용할 수 있도록 하므로서, 폐분체도료를 지정된 매립장소에 매립해야 하는 종래의 문제점을 해소할 수 있는 효과가 있다.As described above, the waste powder paint generated during the powder coating process is collected to remove impurities, and then mixed with the asphalt used in the manufacture of ascone at a predetermined ratio, thereby allowing the waste powder paint to be disposed at a designated landfill site. There is an effect that can solve the conventional problems to be buried.
아스콘제품의 품질이 밀도와, 안정도, 공극률, 포화도 및, 후로우등이 향상되는 효과가 있다.Ascon product quality has the effect of improving density, stability, porosity, saturation, and flow.
