여기서, 상기 DOP는 보호덮개의 경도를 조절하기 위한 것으로, 63 중량부를 초과하게 되면 보호덮개의 경도가 떨어지고 상기 63 중량부보다 낮아지게 되면 경도가 높아지게 된다. 상기 가공조제는 보호덮개를 성형할 때 물성을 조절하기 위한 것이고, 상기 S-T는 배합된 조성물이 실린더 내에서 용융되어 압출될 때 실린더의 내벽에 붙는 현상을 방지하기 위한 것이며, 상기 AC-629는 보호덮개의 표면을 매끄럽게 하는 왁스 역할을 한다.Here, the DOP is for controlling the hardness of the protective cover, the hardness of the protective cover is lowered if it exceeds 63 parts by weight, the hardness is increased when the lower than 63 parts by weight. The processing aid is to control the physical properties when molding the protective cover, the ST is to prevent the phenomenon that the blended composition adheres to the inner wall of the cylinder when the melt is extruded in the cylinder, the AC-629 is protected It acts as a wax to smooth the surface of the cover.
한편, 상기한 바와 같은 조성물들을 이용하여 본 발명의 보호덮개를 제조하는 방법을 도 1을 참조하여 구체적으로 설명하면 다음과 같다,On the other hand, the method for producing a protective cover of the present invention using the composition as described above with reference to Figure 1 in detail as follows,
상기 도 1에 도시한 바와 같이, 전술한 표 1의 조성물들을 배합하고, 이를 호퍼에 투입한다. 상기 호퍼에 투입된 배합물은 실린더의 내부로 공급되는데, 상기 실린더는 3단계로 이루어진다. 즉, 상기 실린더는 3부분으로 이루어지고 가열되는 온도에 차이가 있으며, 구체적으로는 입구의 온도는 120±3℃이고 중간부분의 온도는 105±3℃이고 끝부분의 온도는 130±3℃이다. 이때 상기 실린더의 스크류 회전수는 500rpm이 바람직하다.As shown in FIG. 1, the compositions of Table 1 described above are blended, and these are put into a hopper. The compound injected into the hopper is supplied into the cylinder, and the cylinder has three stages. That is, the cylinder is composed of three parts and there is a difference in the heating temperature, specifically, the temperature of the inlet is 120 ± 3 ℃, the temperature of the middle portion is 105 ± 3 ℃ and the temperature of the end is 130 ± 3 ℃ . At this time, the screw rotation speed of the cylinder is preferably 500rpm.
이후, 상기 배합물은 실린더의 각 단계별로 가열되어 젤 상태로 용융되어진 후, 보호덮개 형상의 다이스를 통과하면서 보호덮개 형상을 가지는 고형체가 인출된다. 상기 인출된 고형체는 냉각수를 통과하면서 식혀지게 되고, 이후 롤러에 의해 인발되고, 약 0.5m의 길이로 절단된다. 이때 상기 다이스의 온도는 140℃이고, 인발속도는 10rpm이 바람직하다. 또한 상기 냉각수의 온도는 20℃가 이상적이다.Thereafter, the compound is heated in each stage of the cylinder to be melted in a gel state, and then a solid having a protective cover shape is drawn out while passing through a protective cover-shaped die. The drawn solid is cooled while passing through the cooling water, then drawn out by a roller, and cut to a length of about 0.5 m. At this time, the temperature of the die is 140 ℃, the drawing speed is preferably 10rpm. In addition, the temperature of the cooling water is ideally 20 ℃.
