Description
본 발명은 열가소성수지를 이용하여 자연산 왕골 이나 인초를 대신하여 사용할 수 있는 인조 풀을 제조하는 방법에 관한 것으로서, 돗자리 또는 바닥용 깔개등을 제조할 수 있는 인조 풀을 얻기 위한 것이다.The present invention relates to a method of manufacturing artificial grass that can be used in place of natural royal bone or incho using thermoplastic resin, and to obtain an artificial pool capable of manufacturing a mat or a floor covering.
통상의 자연산 왕골이나 인초는 생활용품의 하나인 돗자리, 바닥용 깔개를 제조하는 재료로 오래 전부터 사용되어 왔다.Ordinary natural royal bones or ingots have been used for a long time as a material for manufacturing mats and floor coverings, one of household goods.

이하 첨부도면에 의거 보다 상세하게 설명하면 다음과 같다.When described in more detail based on the accompanying drawings as follows.
제1과정, 도 1a와 같이 통상의 사출기와 유사한 불로어 방식의 압출기로 풍선형태의 연속적인 원통형 필름을 압출한다.In the first process, a continuous cylindrical film in the form of a balloon is extruded with a blower type extruder similar to a conventional injection molding machine as shown in FIG. 1A.
제2과정, 도 1b와 같이 상기 원통형 필름을 압착롤러를 이용하여 두 겹의 필름으로 납작하게 하고 압작된 필름의 양단을 커터날로 양분하여 단일 필름으로 분할한다.In the second process, as shown in FIG. 1B, the cylindrical film is flattened into two layers of film using a compression roller, and both ends of the compressed film are divided into cutter blades and divided into a single film.
제3과정, 도 1c와 같이 양분된 단일 필름을 길이방향을 당겨 연신함으로서 연신방향의 섬유질이 형성된다.In the third process, the stretched fiber is formed by drawing the bisected single film in the longitudinal direction as shown in FIG. 1C.
제4과정, 도 1d와 같이 연신된 필름을 스플리팅 롤러에 통과시켜 로울러에 형성되어 있는 핀형상의 칼에 의하여 연신방향의 직각방향으로 넓혀주면서 칼날의 절개에 의하여 불규칙한 그물망 형태의 조직으로 스플리팅 가공한다.In the fourth process, as shown in FIG. 1D, the stretched film is passed through a splitting roller to be spread in an irregular network form by cutting the blade while widening it in the direction perpendicular to the drawing direction by a pin-shaped knife formed in the roller. Pleating process.
제5과정, 도 1e와 같이 스플리팅된 필름을 원통의 다이스를 통과시켜 하나의 합사형태의 끈으로 만듬과 동시에 향료 또는 방충재 등을 투입한다.In the fifth process, as shown in FIG. 1E, the split film is passed through a cylindrical die to form a single braided string, and at the same time, a fragrance or insect repellent is added.
제6과정, 합사형태의 끈으로 뭉쳐진 원통형 합사형태의 끈의 표면에 표면제를 도포하여 완성하는 과정을 갖는다.The sixth process has a process of applying the surface agent to the surface of the cylindrical braided yarn strapped together by the braided yarn.
상기와 같은 공정을 이루는 본 발명의 각각 과정에 대한 작용을 설명한다.The operation of each process of the present invention constituting the above process will be described.
제1과정의 필름제조 공정은 압출기(1)에 열가소성수지(2)를 투입하여 바람과 스크류의 작용으로 다이스(3)로부터 연속적으로 인플레이션시켜 원통형의 필름(10)으로 압출한다.In the film manufacturing process of the first process, the thermoplastic resin 2 is introduced into the extruder 1 and continuously inflation from the die 3 by the action of wind and screw to extrude into the cylindrical film 10.
이때, 압출되는 원통형의 필름(10)의 지름은 200~300mm이고 필름의 두께는 3,400 ~ 3,900denier가 바람직하다.At this time, the diameter of the cylindrical film 10 to be extruded is 200 ~ 300mm and the thickness of the film is preferably 3,400 ~ 3,900denier.
이렇게 압출된 원통형의 필름(10)은 블로우성형 압출기(1)의 압출온도가 90~250℃로서 사용되는 열가소성 수지의 특성에 따라 결정되는 것으로서 폴리프로필렌(Poly- propylene)인 경우에는 110℃에서 압출하고 폴리에틸렌(Polyethylene)은 보다 낮은 약 80℃ 내외에서 압출한다.The cylindrical film 10 extruded as described above is determined according to the characteristics of the thermoplastic resin used as the extrusion temperature of the blow molding extruder 1 at 90 to 250 ° C. In the case of polypropylene, the extrusion film is extruded at 110 ° C. Polyethylene is extruded around lower than about 80 ℃.
이렇게 압출되는 원통형의 필름(10)은 다이스(3)에서 압출되는 동시에 외부의 공기와 접촉하여 냉각되는 과정에서 그 표면이 불규칙한 요철(凹凸)이 형성된다.The cylindrical film 10 to be extruded in this way is extruded from the die 3 and at the same time the irregular surface of the irregular surface is formed in the process of cooling in contact with the outside air.
이러한 제1과정을 거처 압출된 원통형의 필름(10)은 다음의 제2과정으로 진행되는데 이 과정에서는 풍선처럼 부풀은 원통형의 필름(10)을 압착하여 두 겹의 필름(10)으로 납작하게 한다.The cylindrical film 10 extruded based on the first process proceeds to the next second process, in which the flattened cylindrical film 10 is compressed into a flat two-layer film 10. .
이렇게 납작해진 필름(10)의 양단에 커터칼(5)을 삽입하여 절개하고 분리함으로써 단일필름(11)으로 양분한다.The cutter knife 5 is inserted into both ends of the flattened film 10 and then cut and separated, thereby dividing into a single film 11.
이러한 제2과정은 상기 제1과정에서 원형의 풍선형태로 압출하는 것이 압출된 필름의 두께를 보다 균일하게 유지 할 수 있는 장점을 갖게 되고 외부의 공기와 접촉하여 보다 안정된 필름을 얻을 수 있기 때문이다.This second process is because the extrusion in the form of a circular balloon in the first process has the advantage of maintaining the thickness of the extruded film more uniformly and can contact the outside air to obtain a more stable film .
본 제2과정에서 분리된 단일필름(11)은 제3과정의 연신가공을 행하게 되는데 이는 단일필름(11)의 온도가 약 50 ~ 200℃의 범위 내에서 6 ~ 8배의 연신율을 갖는 연신필름(12)으로 가공된다.The single film 11 separated in this second process is subjected to the stretching process of the third process, which is a stretched film having an elongation of 6 to 8 times in the temperature range of the single film 11 is about 50 ~ 200 ℃ It is processed into 12.
이렇게 연신된 연신필름(12)은 연신방향으로 분자배열이 이루어지면서 매우 조밀한 섬유질이 생성되는데 이는 연신방향에 대한 인장력을 갖게함과 아울러 섬유질 결방향의 직각방향으로 용이하게 분리될 수 있는 조건을 충족하게 된다.The stretched stretched film 12 thus forms a very dense fiber as the molecular arrangement is made in the stretching direction, which has a tensile force in the stretching direction and conditions that can be easily separated in the direction perpendicular to the fiber grain direction. Will be satisfied.
상기의 제3과정에서 연신된 연신필름(12)은 다음의 제4과정에서 스플리트로울러의 작용에 의하여 섬유질 결방향의 직각으로 인장력을 가하여 동시에 스플리트로울러에 형성되어 는 칼날에 의하여 부분절개를 시켜 섬유질을 이완하여 줌으로서 불규칙한 그물망을 형성하는 과정을 수행하는데 이 제4과정의 장치는 롤러형상에 나선형의 날카로운 칼날을 부착한 스플리트롤러(6)의 구조를 갖는다.The stretched film 12 stretched in the third process is subjected to a partial incision by a blade formed at the same time by applying a tensile force at a right angle in the fiber grain direction by the action of the split roller in the fourth process. The process of the fourth process has a structure of a split controller 6 attached with a spiral sharp blade in the shape of a roller.
이 스플리트롤러(6)는 중앙을 기준으로 나선방향이 대응되는 형태로서 스플리트롤러(6)의 회전에 의하여 나선방향은 회전축의 바깥으로 밀어내는 힘을 발생한다.The split controller 6 has a form in which the spiral direction corresponds to the center, and the spiral direction generates a force pushing the spiral direction out of the rotation shaft by the rotation of the split controller 6.
위와 같은 스플리트롤러(6)를 약 300rpm의 속도로 회전시키고 상기 연신필름(12)을 접촉시켜 약 160 ~ 240m/min의 속도로 이동시키면 스플리트롤러(6)의 표면에 형성된 날카로운 칼날이 연신필름(12)의 표면과 마찰하여 섬유질의 결방향에 대하여 직각방향으로 넓혀주어 섬유질이 불규칙한 그물망형상으로 절개된 필름(13)으로 형성되게 된다.Rotating the above-described splitter 6 at a speed of about 300rpm and contacting the stretched film 12 to move at a speed of about 160 ~ 240m / min sharp blade formed on the surface of the splitter 6 is stretched By rubbing against the surface of the film 12 and widening in a direction perpendicular to the grain direction of the fiber, the fiber is formed into a film 13 cut into an irregular mesh shape.
이렇게 형성된 그물망형상으로 절개된 필름(13)은 다음의 제5과정에서 하나의 합사형태의 끈으로 뭉쳐졌을 때 섬유질 사이에 작은 공간부를 갖고 있는 합사형태의 끈 필름(14)으로 형성되게 된다.The film 13 cut into the mesh shape thus formed is formed of a braid-shaped string film 14 having a small space between fibers when agglomerated with a single braided string in the following fifth process.
즉, 제5과정의 공정구성은 구성체 외부에 히터(8)를 장착하여 구성체를 열가소성수지의 변형온도에 적합한 온도로 가열하고 있으며, 그물망 형상으로 부분절개된 필름(13)을 합사형태의 끈으로 변환시키기 위하여 다이스(7)를 통과하여 원형의 합사형태의 끈(14)으로 뭉치게 되는 것이며 이의 인입구에는 합사형태의 끈 조절기(7a)를 설치하여 뭉쳐지는 합사형태의 끈(14)의 지름을 조절할 수 있게되며 그 뭉처지는 과정을 용이하게 하기 위하여 히터(8)를 부착한 것이다.That is, in the fifth process, the heater 8 is mounted on the outside of the structure to heat the structure to a temperature suitable for the deformation temperature of the thermoplastic resin, and the film 13 partially cut into a mesh shape is formed by a braided string. In order to convert through the die (7) it will be bundled into a circular braided string 14, and the inlet is provided with a braided string regulator (7a) to install the diameter of the braided string 14 It is possible to adjust and to attach the heater (8) to facilitate the uniting process.
한편, 상기 과정에서 뭉쳐지는 합사형태의 끈(14)의 지름을 조절하면 그 뭉쳐지는 지름에 대하여 그물망필름(13)에서 수치가 차지하는 충전율은 약 70 ~ 90%가 된다.On the other hand, by adjusting the diameter of the string 14 of the braided bundle in the above process, the filling rate occupied by the numerical value in the net film 13 with respect to the diameter of the bundle is about 70 ~ 90%.
위와 같이 가공된 제5과정의 합사형태의 끈(14)은 비교적 탄력이 있는 합사형태의 끈체가 되지만 표면의 미관이 좋지 않으며 감촉이 합성수지의 질감이 그대로 들어나고 합성수지의 특유한 냄새가 나기 때문에 이를 보다 자연산에 가까운 형태로 가공하는 것이 바람직하며, 특히 자연산이 갖고 있는 단점을 보완하도록 합사형태의 끈으로 변환시키기 위한 다이스(7)를 통과할 때 향료를 약 2 ~ 3중량%를 첨가하고 항균과 건강을 위하여 원적외선 방출제 또는 방염제, 변색방지제 등을 약 10 중량% 첨가한다.The braided yarn 14 of the fifth process, which is processed as described above, becomes a braided braid that is relatively elastic, but the aesthetics of the surface are not good, and the texture of the synthetic resin is intact and the peculiar smell of the synthetic resin appears. It is preferable to process the product into a form close to natural acid, and in particular, add about 2 to 3% by weight of fragrance when passing through the die 7 for converting into a braided string to compensate for the disadvantages of natural acid, For this purpose, about 10% by weight of a far infrared ray releasing agent or flame retardant or discoloration preventing agent is added.
이렇게 제5과정을 거친 합사형태의 끈(14)은 제5과정의 구성체와 일체로 구성되고 지름이 약 1.0 ~ 1.5mm인 표면제 투입다이스(9)를 통과시키는 제6과정을 행하게 되는데, 이 제6과정의 표면제 투입다이스(9)의 내측에는 표면제투입구(9a)를 전둘레에 천공하여 피막제를 투입하여 약 160 ~ 250m/min의 속도로 통과시키면 표면제가 코팅된 인조풀(20)이 생산된다.Thus, the braided string 14 having the fifth process is integrally formed with the structure of the fifth process and performs a sixth process of passing the surface injection die 9 having a diameter of about 1.0 to 1.5 mm. Inside the surface agent injection die 9 of the sixth process, the surface agent injection hole 9a is perforated in the entire circumference, and the coating agent is introduced and passed through at a speed of about 160 to 250 m / min.

이때, 표면제 투입다이스(9)를 통과되는 속도가 100 ~ 160m/min이면 인조풀(20)의 표면이 딱딱한 느김을 주게되고 250m/min이상이면 인조풀(20)의 표면이 너무 얇고 거칠어지는 문제점이 발생한다.At this time, if the speed passing through the surface-injection die 9 is 100 ~ 160m / min gives a surface of the artificial pool 20 is a hard slow, if the surface of the artificial pool 20 is too thin and rough if more than 250m / min A problem occurs.
그리고, 표면제투입다이스(9)의 통과지름이 1.0mm이면 표면제(15)를 도포하고 통과되는 순간 압축력이 해제되어 인조풀(20)의 지름이 1.1 ~ 1.2mm로 팽창하게 되어 자연산의 인초가 가지는 평균적인 지름의 양호한 인조풀(20)을 얻게 된다.Then, if the passing diameter of the surface preparation injection die (9) is 1.0mm, the surface agent 15 is applied and the compressive force is released at the time of passing, and the diameter of the artificial pool 20 expands to 1.1 to 1.2mm, and the natural inflorescence With this, a good artificial pool 20 having an average diameter is obtained.
위와 같이 제조된 본 발명의 인조풀은 자연산의 왕골이나 인초를 대신하여 충분히 활용될 수 있는 장점을 갖게 되며, 특히 자연산의 인초는 최대길이 89 ~ 105Cm에 이르는 극히 제한된 길이를 갖고 있으나 본 발명에 의하여 제조되는 인조풀은 그 길이를 무한하게 제조할 수 있는 것으로서, 보다 다양한 크기의 돗자리 또는 바닥용 깔개를 제작할 수 있게 되며, 공급이 원할하여 보다 저렴한 제품을 생산할 수 있는 장점을 갖게 되는 것이다.Artificial grass of the present invention prepared as described above has the advantage that can be fully utilized in place of natural royal bone or incho, in particular the natural incho has an extremely limited length up to a maximum length of 89 ~ 105Cm but by the present invention The artificial pool to be manufactured is to be infinitely produced in the length, it is possible to manufacture a mat or floor mat of a variety of sizes, it will have the advantage that can be cheaper to produce a cheaper product.
