본 발명은 고흡수성 수지의 절단 장치 및 이를 이용한 고흡수성 수지의 제조 방법에 관한 것이다.The present invention relates to a device for cutting a super absorbent polymer and a method for producing a super absorbent polymer using the same.
고흡수성 수지(Super Absorbent Polymer, SAP)란 자체 무게의 500 내지 1,000 배 정도의 수분을 흡수할 수 있는 기능을 가진 합성 고분자 물질로서, 개발업체마다 SAM(Super Absorbency Material), AGM(Absorbent Gel Material) 등 각기 다른 이름으로 명명하고 있다. 상기와 같은 고흡수성 수지는 생리용구로 실용화되기 시작해서, 현재는 어린이용 종이 기저귀 등 위생 용품 이외에 원예용 토양 보수제, 토목, 건축용 지수재, 육묘용 시트, 식품 유통 분야에서의 신선도 유지제, 찜질 용품 등의 재료로 널리 사용되고 있다.Super Absorbent Polymer (SAP) is a synthetic polymer material capable of absorbing water of 500 to 1,000 times its own weight.As a developer, super absorbent material (SAM) and absorbent gel material (AGM) They are named differently. Such super absorbent polymers have been put into practical use as physiological tools, and nowadays, in addition to hygiene products such as children's paper diapers, horticultural soil repair agents, civil engineering, building index materials, seedling sheets, freshness-retaining agents, and steaming in the food distribution sector. It is widely used as a material for articles.
상기와 같은 고흡수성 수지를 제조하는 방법으로는 역상현탁중합에 의한 방법 또는 수용액 중합에 의한 방법 등이 알려져 있다. 역상현탁중합에 대해서는 예를 들면 일본 특개소 56-161408, 특개소 57-158209, 및 특개소 57-198714 등에 개시되어 있다. 수용액 중합에 의한 방법으로는 또 다시, 수용액에 열을 가하여 중합하는 열중합 방법, 및 자외선 등을 조사하여 중합하는 광중합 방법 등이 알려져 있다.As a method for producing such a super absorbent polymer, a method by reverse phase suspension polymerization or a method by aqueous solution polymerization is known. Reverse phase suspension polymerization is disclosed in, for example, Japanese Patent Laid-Open Nos. 56-161408, 57-158209, and 57-198714.

이들 도면들을 참조하면, 고흡수성 수지 절단 장치(100)는 지지대(160) 상에서 이동하는 고흡수성 수지(150)가 투입되는 투입부(110), 투입부(110)로 들어온 고흡수성 수지(150)를 절단하는 커터(120), 및 절단된 수지를 배출하는 배출부(140)를 포함한다.Referring to these drawings, the super absorbent polymer cutting device 100 is a supernatant absorbent resin 150 is introduced into the input unit 110, the input unit 110, the super absorbent polymer 150 moving on the support 160, Cutter 120 to cut the, and the discharge unit 140 for discharging the cut resin.
지지대(160)는 특별히 한정되는 것은 아니지만, 고흡수성 수지(150)를 이송시키기 위하여 하나의 컨베이어 벨트 또는 둘 이상의 컨베이어 벨트의 조합으로 이루어질 수 있다. 둘 이상의 컨베이어 벨트의 조합으로 이루어지는 경우, 그 연결 부위는 커터(120)에 대응하는 부위일 수 있다.The support 160 is not particularly limited, but may be formed of one conveyor belt or a combination of two or more conveyor belts to transfer the superabsorbent polymer 150. In the case of a combination of two or more conveyor belts, the connection site may be a site corresponding to the cutter 120.
커터(120)는, 예를 들어, 롤러형 커터일 수 있다. 구체적인 예에서, 커터(120)는 표면에 연속적인 패턴 날(122)이 형성되어 있을 수 있다. 롤러형 커터의 회전체(121)가 회전하면서 패턴 날(122)의 형상대로 고흡수성 수지(150)가 절단될 수 있다.The cutter 120 may be, for example, a roller-type cutter. In a specific example, the cutter 120 may be formed with a continuous pattern blade 122 on the surface. As the rotating body 121 of the roller-type cutter rotates, the superabsorbent polymer 150 may be cut in the shape of the pattern blade 122.
회전체(121)에서 돌출되어 있는 패턴 날(122)의 높이는 투입되는 고흡수성 수지의 높이보다 크기만 하면 특별히 한정되지는 않는다. 투입되는 고흡수성 수지의 높이는 공정 조건에 따라 달라질 수 있으므로, 특별히 한정되지 않는다.The height of the pattern blade 122 protruding from the rotor 121 is not particularly limited as long as it is larger than the height of the superabsorbent polymer. Since the height of the superabsorbent polymer to be added may vary depending on the process conditions, it is not particularly limited.
예시적인 실시예에서, 패턴 날(122)의 끝단은 톱니 형상으로 형성될 수 있다. 이 경우, 톱니는 패턴 날(122)과 동일한 평면 상에 형성될 수도 있지만, 상기 평면에 어긋나 형성될 수도 있다. 톱니가 패턴 날(122)과 동일한 평면에 어긋나 형성될 경우, 인접하는 두 개의 톱니는 서로 다른 방향으로 어긋나 있을 수 있다.In an exemplary embodiment, the ends of the pattern blade 122 may be formed in a sawtooth shape. In this case, the saw tooth may be formed on the same plane as the pattern blade 122, but may be formed shifted from the plane. When the teeth are shifted from the same plane as the pattern blade 122, two adjacent teeth may be shifted in different directions.
패턴 날(122)의 형태는 다각형 및 원형으로 이루어진 군에서 선택되는 하나 이상일 수 있다. 상기 다각형은 특별히 한정되지는 않지만, 예를 들어, 삼각형, 사각형, 오각형 및 육각형으로 이루어진 군에서 선택되는 하나 이상일 수 있다.The shape of the pattern blade 122 may be one or more selected from the group consisting of polygons and circles. The polygon is not particularly limited, but may be, for example, one or more selected from the group consisting of triangles, squares, pentagons, and hexagons.
예시적인 실시예에서, 패턴 날(122)은 한 가지 형태가 연속적으로 구성될 수도 있지만, 다른 형태가 혼합된 형태로 구성될 수도 있다.In an exemplary embodiment, the pattern blade 122 may be configured in one form continuously, but may be configured in a mixture of other forms.
패턴 날(122)로 정의되는 패턴의 크기는 공정 상 원하는 사이즈에 따라 다양하게 적용이 가능하다. 예를 들어, 평균 직경 5 mm 내지 100 mm 범위로 설정할 수 있지만, 이것만으로 한정되는 것은 아니다. 5 mm 미만인 경우에는 패턴 날(122) 사이 간격이 너무 협소하여 절단 과정에서 고흡수성 수지(150)가 밀려 불완전한 절단이 될 수 있고, 100 mm 초과인 경우에는 절단 공정으로 인한 원하는 효과를 얻기 어렵다는 문제가 있다.The size of the pattern defined by the pattern blade 122 may be variously applied according to a desired size in the process. For example, although it can set in the range of 5 mm-100 mm of average diameters, it is not limited to this. In the case of less than 5 mm, the spacing between the pattern blades 122 is so narrow that the superabsorbent polymer 150 may be pushed in the cutting process, resulting in incomplete cutting. There is.
예시적인 실시예에서, 지지대(160)는 별도의 구동 장치가 없는 것일 수 있다. 이 경우, 커터(120)의 회전력으로 고흡수성 수지(150)를 이송시키는 것도 가능하다.In an exemplary embodiment, the support 160 may be without a separate driving device. In this case, it is also possible to transfer the superabsorbent polymer 150 by the rotational force of the cutter 120.
고흡수성 수지(150)를 사이에 두고, 패턴 날(122)에 대응하는 위치에서 패턴 날(122)이 일부 함입될 수 있도록 홈(161)이 형성될 수 있다. 이 경우, 고흡수성 수지(150)가 일부 절단되지 않아 발생하는 불량을 방지할 수 있고, 보다 확실한 절단 효과를 가질 수 있다.The groove 161 may be formed to partially enclose the pattern blade 122 at a position corresponding to the pattern blade 122 with the superabsorbent polymer 150 therebetween. In this case, it is possible to prevent a defect caused by not cutting part of the super absorbent polymer 150, and may have a more reliable cutting effect.
배출부(140)의 경우에는 도 1에서와 같이, 지지대(160)가 연장되어 있을 수 있다. 하지만, 이것만으로 한정되는 것은 아니고, 별도의 지지대(160) 없이 절단된 고흡수성 수지(150)가 낙하하여 수납되도록 할 수도 있다.In the case of the discharge unit 140, as shown in Figure 1, the support 160 may be extended. However, the present invention is not limited thereto, and the superabsorbent polymer 150 cut without the support 160 may be dropped and accommodated.
한편, 도 1 및 2를 참조하여 고흡수성 수지 절단 장치의 일 구동예에 대해 설명하면, 컨베이어 벨트로 형성된 지지대(160)의 투입부(110) 상으로, 중합된 고흡수성 수지(150)가 투입되고, 고흡수성 수지(150)는 상기 지지대(160) 상에 안착되어 투입부(110)에서 배출부(140) 방향으로 이동할 수 있다. 이때, 지지대(160)의 이동은 상기 설명에서와 같이, 구동 장치에 의해 투입부(110)에서 배출부(140) 방향으로 이동하거나, 별도의 구동 장치 없이 지지대(160) 상부에 위치하는 커터(120)의 회전력에 의해 이동할 수 있다.Meanwhile, referring to FIGS. 1 and 2, a driving example of the superabsorbent polymer cutting device will be described. The polymerized superabsorbent polymer 150 is introduced onto the feed unit 110 of the support 160 formed of the conveyor belt. The superabsorbent polymer 150 may be seated on the support 160 to move from the input unit 110 to the discharge unit 140. At this time, the movement of the support 160 is moved in the direction of the discharge unit 140 from the input unit 110 by the drive device, as described above, or a cutter located above the support 160 without a separate drive device ( 120 can be moved by the rotational force.
상기 투입부(110)와 배출부(140)에 대해 보다 구체적으로 설명하면, 도 1 상에서 투입부(110)는 커터(120)를 기준으로 지지대(160)의 좌측 상부에 위치한다고 볼 수 있으며, 배출부(140)는 커터(120)를 기준으로 지지대(160)의 우측 상부에 위치한다 볼 수 있다.Referring to the input unit 110 and the discharge unit 140 in more detail, it can be seen that the input unit 110 is located on the upper left of the support 160 on the basis of the cutter 120, The discharge unit 140 may be located on the upper right side of the support 160 with respect to the cutter 120.
지지대(160) 상의 고흡수성 수지(150)는 지지대(160) 상부에 위치하는 커터(120)를 지나면서, 상기 커터(120)의 패턴날(122)에 의해 원하는 사이즈와 형상으로 절단될 수 있다. 상기 고흡수성 수지(150)의 절단되는 사이즈와 형상은 커터(120)에 형성된 패턴날(122)의 패턴 형상 및 크기에 따라 결정될 수 있다. 즉, 상기 커터(120)는, 표면에 연속적인 패턴 날(122)이 형성된 롤러형 커터일 수 있으며, 롤러형 커터의 회전체(121)가 회전하면서 패턴 날(122)의 형상대로 고흡수성 수지(150)가 절단될 수 있다.The superabsorbent polymer 150 on the support 160 may be cut into a desired size and shape by the pattern blade 122 of the cutter 120 while passing through the cutter 120 positioned on the support 160. . The cut size and shape of the superabsorbent polymer 150 may be determined according to the pattern shape and size of the pattern blade 122 formed on the cutter 120. That is, the cutter 120 may be a roller-type cutter having a continuous pattern blade 122 formed on a surface thereof, and the superabsorbent polymer in the shape of the pattern blade 122 may be rotated while the rotating body 121 of the roller-type cutter rotates. 150 may be cut.
다음으로, 상기 절단된 고흡수성 수지(150)는 지지대(160) 상에서 이동하여 지지대(160)가 연장되어 형성된 배출부(140)를 통해 배출될 수 있다. 다만, 이에 한정하는 것은 아니며, 배출부(140)는 별도의 지지대 없이 절단된 고흡수성 수지(150)가 낙하하여 수납되는 형태일 수 있다.Next, the cut superabsorbent polymer 150 may be discharged through the discharge unit 140 formed by extending the support 160 by moving on the support 160. However, the present invention is not limited thereto, and the discharge part 140 may have a shape in which the superabsorbent polymer 150 cut without a separate support drop is accommodated therein.
