Description

스테인레스판의 마찰방지용 고밀도 폴리에틸렌지의 제조방법Manufacturing method of high density polyethylene paper for preventing friction of stainless steel plate

본 발명은 스테인레스판의 제조공장에서 제조되는 스테인레스판을 둥글게 말아 출하시에 서로 접촉되는 스테인레스판이 마찰등에 의하여 긁힌 흠이 발생되는 것을 방지하기 위한 스테인레스판의 마찰방지용 고밀도 폴리에틸렌지의 제조방법에 관한 것이다.The present invention relates to a method for producing a high-density polyethylene paper for preventing friction of a stainless steel plate to prevent the occurrence of scratches caused by friction, etc. of the stainless steel plates rolled round the stainless plate produced in the manufacturing factory of the stainless steel plate round.

종래의 스테인레스판을 제조하는 업체에서는 스테인레스판의 표면의 마찰과 긁힌 흠을 방지하기 위하여 원형으로 권취되는 스테인레스판의 사이에 종이를 끼우게 되는 바, 종이는 종이의 지분에 의한 결함(흠)유발로 인하여 수요가들의 불만을 해소하지 못하고 있는 실정이다.In order to prevent friction and scratches on the surface of the stainless plate, a company that manufactures a conventional stainless plate sandwiches paper between the stainless steel plates wound in a circle. Due to this situation, the consumer's dissatisfaction cannot be resolved.

즉, 적정 폭을 유지하기 위하여 종이를 자를 때 남아있는 지분과 종이를 생산할 때 남아있는 이물이나 지분이 부착되어서 스테인레스판의 표면을 손상시키거나 쉽게 찢어지게되는 문제가 따르게 되었다.That is, in order to maintain an appropriate width, the remaining stake and the remaining foreign matter or stake are attached to the paper when the paper is cut, and the surface of the stainless plate is easily damaged or torn.

본 발명은 상기와 같은 문제점을 해결하기 위하여 신율(종축으로 430-620%, 횡축으로 580-650%정도), 내열강도(100℃ X 30sec), 인장강도(종축으로 510-640Kg/mm2, 횡축으로 510-570Kg/mm2), 인열강도(종축으로 160-241Kg/cm2, 횡축으로 270-385Kg/cm2)를 향상시켜 신율이 거의 없고, 내열강도는 상온에 가깝고(접촉온도에 적응이 쉬우나 80℃이상에서는 열화의 속도가 매우 심함) 인장강도는 종축으로 7Kg/15mm 횡축으로 1.6Kg/15mm이며, 인열강도는 종축으로 25-30g, 횡축으로 45-55g인 종이에비하여 우수한 효율을 발휘되게 한 스테인레스판의 마찰방지용 고밀도 폴리에틸렌지의 제조방법을 제공할 수 있도록 한 것이다.The present invention to solve the above problems elongation (430-620% in the longitudinal axis, 580-650% in the horizontal axis), heat resistance (100 ℃ X 30sec), tensile strength (510-640Kg / mm 2 , longitudinal) the horizontal axis in 510-570Kg / mm 2), tear strength (almost no elongation improves 270-385Kg / cm 2) as 160-241Kg / cm 2, the horizontal axis with the vertical axis, also heat resistant steel is close to room temperature (the contact temperature It is easy to adapt, but the rate of deterioration is very high above 80 ℃) Tensile strength is 7Kg / 15mm on the vertical axis and 1.6Kg / 15mm on the horizontal axis. It is to provide a method for producing a high-density polyethylene paper for preventing friction of the stainless plate exhibited efficiency.

를 혼합하여 제조함을 특징으로 한 것이다.It is characterized by the fact that it is prepared by mixing.

전기에서, HDPE 7000F는 55%에서 함량이 증가되면 인장강도 및 파열강도가 낮아지고, 함량이 감소되면 인장강도 및 파열강도는 높아진다. HDPE 8000F는 10%에서 함량이 높아거나 낮아지면 기본적인 물성(세로장력) 및 제품현상이 불균일하게 된다.In the former, HDPE 7000F increased its tensile strength and bursting strength at 55% and decreased its tensile strength and bursting strength at 55%. If the content of HDPE 8000F is higher or lower at 10%, the basic properties (vertical tension) and product phenomenon become uneven.

LDPE 303은 HDPE 8000F와 같이 8%에서 함량이 높아지거나 낮아지면 기본물성치인 가로장력과 제품형성이 불균일하게 된다. 전분(7000FT3)은 12%가 되어야 제품의 조직이 보강되며 적정비율을 넘거나 부족하면 기본물성의 조직이 이루어지지 않는다.LDPE 303, such as HDPE 8000F, increases or decreases in content at 8%, resulting in non-uniform transverse tension and product formation. Starch (7000FT3) should be 12% to reinforce the organization of the product. If it exceeds or falls short of the proper ratio, the organization of basic properties is not achieved.

EVA(E120A)는 2.5%에서 신축, 방습, 필름의 미끄러지는 현상을 방지하며 2.5%선에서 비닐의 제조과정을 도와준다. FP1-5는 5%를 기준으로 첨가하면 제품의 내열성을 증가시키는데 함량을 높이면 제품의 형성이 잘 되지않고, 함량을 줄이면 내열성이 떨어진다.EVA (E120A) prevents stretch, moisture and film slipping at 2.5% and aids in the manufacturing of vinyl at 2.5%. When FP1-5 is added on the basis of 5%, the heat resistance of the product is increased. If the content is increased, the product is not formed well. If the content is reduced, the heat resistance is poor.

대전방지제(帶電防止劑)는 4%에서 마찰에 의한 물체의 정전기발생을 방지하는 역할을 하는데 함량이 증가되면 제품형성이 불균일하게 되고 함량이 감소되면 정전기발생억제력이 매우 불량하게 된다.Antistatic agent (帶電 防止 劑) serves to prevent the static electricity generation of the object by friction at 4%. When the content is increased, the product formation becomes uneven, and when the content is decreased, the static electricity generating power is very poor.

RB(Rubber)는 3.5에서 EVA역활의 보조제로 사용되는 것으로서 신축, 방습, 미끄럼발생을 방지하게 되는 것인데, 특히 제품의 신축성을 월등히 향상시키며 함량이 증가되면 제품의 형성이 불균일하게되고 함량이 증가되면 신축, 방습, 미끄러짐발생방지작용이 양호하게 발휘되지 못하게 된다.RB (Rubber) is used as an adjuvant of EVA role in 3.5, and it prevents stretching, moisture proof, and slipping. Especially, when the content is increased and the content is increased, the product formation becomes uneven and the content is increased. Stretching, moisture proof, slip prevention prevention action is not exhibited well.

상기 조건을 다음 그림과 표에서 잘 설명해준다. 표 1에서 보는 것처럼 연신율은 본 발명재에 고무를 3.5% 첨가하여 종이에 비하여 월등히 좋은 것을 알 수 있다.The above conditions are illustrated in the following figure and table. As shown in Table 1, the elongation is 3.5% by adding rubber to the present invention, it can be seen that much better than the paper.

즉, 평균적으로 종축 연신이 500%이상인데 반하여, 종이는 거의 없는 것임을 알 수 있다.In other words, the average longitudinal stretch is 500% or more, while the paper is almost absent.

또한 고밀도 폴리에틸렌(HDPE) 7000F는 55%에서, 고밀도폴리에틸렌(HDPE) 8000F는 10%에서 최적임을 알 수 있다. 그림 1은 표 1의 각 성분별 신율에 대한 표시이다. 내열강도는 불소수지(FP2-5)를 5%정도 첨가할 때부터 좋은 결과를 나타내었다.In addition, it can be seen that HDPE 7000F is optimal at 55% and HDPE 8000F is 10%. Figure 1 shows the elongation for each component in Table 1. The heat resistance showed good results when 5% of fluorine resin (FP2-5) was added.

표 2에는 나타나지 않았지만 본 발명재에 전분(유화제:POP)7000FT3를 12%정도 첨가하였을 때 내열강도가 100℃/30sec 이상되었다.Although not shown in Table 2, when the starch (emulsifier: POP) 7000FT3 was added about 12% to the present invention, the heat resistance was 100 ° C / 30 sec or more.

표 3은 각 성분별 종횡의 인장강도를 나타냈는데 본 발명재는 고밀도폴리에틸렌을 55%첨가했을 때 종축으로 620kg/cm2이고, 횡축으로 540인데 반하여 종이는 종축으로 7kg/15mm이고, 횡축으로 1.6kg/15mm로 나타났다.Table 3 shows the tensile strength of each component in the longitudinal direction. The present invention is 620kg / cm 2 in the vertical axis and 540 in the horizontal axis when 55% of high density polyethylene is added, while paper is 7kg / 15mm in the vertical axis and 1.6kg in the horizontal axis. / 15mm.

그림 3은 각 성분별 인장강도를 나타냈다. 또한 인열강도를 보면 본 발명재는 위의 각 성분에 불소수지를 5% 첨가하여 내열성이 아주 우수한데 표 4와 같이 인열강도가 종축으로 160에서 241까지 나왔고, 횡축으로 270-385까지 나왔고, 종이는 종축으로 25-30이고, 횡축으로 45-50까지 나왔다. 또한 본 발명재에는 비닐의 정전기발생을 방지하는 역할을 하는 대전방지제(帶電防止劑)를 4% 정도 첨가하여 종이에서 잘 발생하는 정전기현상을 예방할 수 있었다. 또한 표 5에서 알 수 있는 바와 같이 냉간압연시 본 발명재를 사용할 때 동일한 압하율 조건하에서도 광택이 향상되었으며 스테인레스판사이의 층간마찰을 해소시킬 수 있었다.Figure 3 shows the tensile strength of each component. In addition, the tearing strength of the present invention is 5% by adding fluorine resin to each of the above components, the heat resistance is very excellent, as shown in Table 4, tear strength was from 160 to 241 in the vertical axis, 270-385 in the horizontal axis, The paper was 25-30 in the longitudinal axis and 45-50 in the horizontal axis. In addition, the present invention was able to prevent the static phenomena well generated in the paper by adding about 4% of the antistatic agent (帶電 防止 劑) that serves to prevent the generation of static electricity of the vinyl. In addition, as shown in Table 5, when using the present invention during cold rolling, the gloss was improved even under the same rolling reduction conditions, and the interlayer friction between the stainless plates could be eliminated.

이와 같은 본 발명은 인장강도는 종축으로 7kg/15mm이고 횡축으로는 1.6kg/15mm이며, 인열강도는 종축으로 25-30g, 횡축으로 45-55g인 종이에 비하여 매우 우수한 효율을 발휘시킬 수 있음과 아울러 종래의 종이에 비하여 스테인레스판에 잔존하는 오일(OIL)에 의한 열처리후의 결함해소와 냉간압연시 본 발명재를 사용시 동일한 압하율 조건하에서도 광택을 향상시킬 수 있고, 스테인레스판사이의 층간마찰을 해소킬 수 있게 되어 스테인레스판의 표면손상을 방지할 수 있는 효과가 있다.The present invention has a tensile strength of 7kg / 15mm in the longitudinal axis and 1.6kg / 15mm in the horizontal axis, tear strength is 25-30g in the longitudinal axis, 45-55g in the horizontal axis can exhibit a very good efficiency. In addition, it is possible to improve the gloss even under the same rolling reduction conditions when the present invention material is used in cold rolling and the defects after heat treatment by oil remaining in the stainless steel plate (OIL) as compared to the conventional paper. It can be eliminated, there is an effect that can prevent the surface damage of the stainless plate.
