Abstract
Description
본 발명은 디프코드지의 제조방법에 관한 것으로, 더욱 상세하게는 고무와 섬유의 접착력이 월등히 향상된 디프코드지의 제조방법에 관한 것이다.The present invention relates to a method for producing a diff code paper, and more particularly to a method for producing a diff code paper with improved adhesion of rubber and fibers.
일반적으로 타이어코드, 컨베이어벨트등으로 사용되는 고무보강제품은 폴리에스테르 또는 폴리아미드등과 같은 산업용 섬유에 고무를 피복하는 방법에 의해 제조되고 있다. 그러나, 이와 같이 고무보강섬유의 제조시 섬유에 고무를 직접 입힐 경우 섬유와 고무 사이의 접착력이 약하기 때문에 섬유와 고무가 쉽게 분리되는 문제점이 있다.Rubber reinforcement products generally used for tire cords, conveyor belts, etc. are manufactured by coating rubber on industrial fibers such as polyester or polyamide. However, when the rubber is directly coated on the fiber during the manufacture of the rubber reinforcing fiber as described above, there is a problem in that the fiber and rubber are easily separated because the adhesive force between the fiber and the rubber is weak.
이러한 문제점을 해결하기 위한 대안으로 고무보강제품 제조시에 섬유에 접착조성물을 처리한 후 고무를 피복하므로써 섬유와 고무 사이의 접착력을 향상시키는 방법이 일반적으로 이용되고 있다. 이와 같이 접착조성물을 섬유 표면에 처리하여 건조하는 것을 디핑(Dipping)공정이라 한다.As an alternative to solve this problem, a method of improving the adhesion between the fiber and the rubber by coating the rubber after treating the adhesive composition to the fiber during manufacture of the rubber reinforcement products is generally used. In this way, the adhesive composition is treated on the surface of the fiber and dried, which is called a dipping process.
디핑공정에 사용되는 접착조성물로는 통상적으로 레소시놀포르말린락텍스 (RFL)로 이루어진 조성물이 사용되고 있으며, 특히 폴리에스테르 섬유의 경우에는 그 분자 자체의 화학구조의 치밀성으로 인해 고무와의 친화성, 반응성이 다른 섬유에 비해 떨어지므로, 이를 보완하기 위하여 아닐린계 화합물에 섬유를 침적한 후 건조시키는 공정을 추가한 2욕법으로 처리하고 있다.As the adhesive composition used in the dipping process, a composition consisting of resorcinol formalin lactex (RFL) is usually used. Especially, in the case of polyester fiber, due to the compactness of the chemical structure of the molecule itself, Since the reactivity is inferior to other fibers, in order to compensate for this, it is treated by a two-bath method in which a step of immersing and drying the fibers in the aniline compound is added.
디핑공정은 레소시놀포르말린라텍스(RFL)로 이루어진 접착조성물 용액에 산업용 섬유를 침적하고, 건조, 열처리 및 열안정화하는 방법으로 수행된다. 접착조성물처리 후의 건조 및 열처리에 의해 레소시놀포르말린라텍스(RFL) 용액내에 포함되어 있는 수분이 증발되고, 고형분의 라텍스와 섬유가 물리적, 화학적으로 결합하여 섬유와 고무 사이의 접착력이 향상된다. 이러한 건조 및 열처리공정시 레소시놀포르말린라텍스(RFL) 용액에 포함되어 있는 수분을 완전히 제거하여야 하며, 이들 수분이 완전히 제거되지 않는 경우에는 레소시놀포르말린라텍스(RFL) 용액내에 포함된 수분이 가수분해를 일으켜 활성기를 소실시키므로 접착력이 저하되는 문제점이 발생한다.The dipping process is performed by depositing, drying, heat treating and thermally stabilizing industrial fibers in a solution of an adhesive composition composed of resorcinol formalin latex (RFL). By drying and heat treatment after the adhesive composition treatment, the water contained in the resorcinol formalin latex (RFL) solution is evaporated, and the latex and the fibers of the solid content are physically and chemically bonded to improve the adhesion between the fiber and the rubber. During this drying and heat treatment process, the water contained in the Lesosinol formalin latex (RFL) solution must be completely removed. If the water is not completely removed, the water contained in the Lesosinol formalin latex (RFL) solution is Since the decomposition causes the activator to be lost, a problem arises in that the adhesion is lowered.
이와 같은 문제점을 해결하기 위하여 종래로 부터 사용되어 온 건조공정의 일례는 송출된 폴리에스테르 섬유를 아닐린계 화합물의 제 1조에 침적한 후 제 1건조부(DRY ZONE-I) 및 제 2건조부(DRY ZONE-II)를 지나 고온부(HOT ZONE)를 통과시켜 건조시킨다음 레소시놀포르말린라텍스(RFL) 용액이 담지된 제 2조에 침적한 후 디프부(DIP ZONE) 및 노말라이징부(NORMALIZING ZONE)를 통과시켜 건조시키는 것이다.One example of a drying process that has been conventionally used to solve such a problem is to deposit the polyester fibers sent out in the first article of the aniline-based compound, followed by the first drying section (DRY ZONE-I) and the second drying section ( After drying through DRY ZONE-II), it is passed through HOT ZONE, and then dipped in Article 2 in which Lesocinol formalin latex (RFL) solution is loaded, followed by DIP ZONE and NORMALIZING ZONE. It is passed through to dry.
그러나, 이와 같은 종래의 건조방식에 의한 경우에는 수분이 완전히 제거되지 않기 때문에 고무보강제품의 제조에 있어서 최종 제품의 품질을 좌우하는 가장 중요한 요소인 섬유와 라텍스와의 접착력를 저하시켜 최종 고무보강제품에 있어 섬유와 고무가 서로 박리되는 현상이 발생되는 문제점이 있다.However, in the case of the conventional drying method, since moisture is not completely removed, the final rubber reinforcement product is degraded by lowering the adhesion between fibers and latex, which is the most important factor in the quality of the final product in the manufacture of rubber reinforcement products. There is a problem that the phenomenon that the fiber and the rubber is peeled off each other.
본 발명의 목적은 상술한 종래기술상의 문제점을 해결하는 것으로, 고무보강제품에서 고무와 섬유 사이의 접착력을 결정하는 섬유와 라텍스간의 접착력을 향상시킨 디프코드지의 제조방법을 제공하는 것이다.SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a method for producing a diff code paper which improves the adhesion between the fiber and the latex, which determines the adhesion between the rubber and the fiber in the rubber reinforcement product.
즉, 본 발명은 접착제조성물 용액에 산업용 섬유를 침적한 후 건조시켜 디프코드지를 제조함에 있어서, 아래와 같은 조건으로 저온 플라즈마 처리를 한 후 고무접착조성물 용액에 침지함을 특징으로 하는 디프코드지의 제조방법을 제공하는 것이다:In other words, the present invention is to produce a dip code paper by immersing the industrial fibers in the adhesive composition solution and then dried, the low temperature plasma treatment under the following conditions to produce a dip code paper, characterized in that immersed in a rubber adhesive composition solution To provide:
압력 : 대기압Pressure: atmospheric pressure
분위기 가스 : 아세톤 및 불활성 기체Atmosphere Gas: Acetone and Inert Gas
분위기 농도 : 5∼50ppmAtmosphere concentration: 5-50 ppm
코드지와 방전판 사이의 간격(L) : 10∼100㎜Spacing (L) between coded paper and discharge plate: 10-100mm
본 발명에서와 같이 고무접착조성물에 침지시키기 전에 저온 플라즈마 처리를 행하면 화학적으로는 소수성기가 친수성기로 변화되므로 용액에 대한 표면장력이 증가되고, 물리적으로는 섬유 표면에 돌기가 형성되어 접착면적이 확대되므로 전체적으로 섬유와 라텍스 및 섬유와 고무 사이의 접착력이 향상된다.If the low-temperature plasma treatment before the immersion in the rubber adhesive composition as in the present invention, the hydrophobic group is chemically changed to a hydrophilic group, so that the surface tension of the solution is increased, and physically, projections are formed on the surface of the fiber, thereby increasing the adhesive area. Overall, the adhesion between fibers and latex and between fibers and rubber is improved.
본 발명에서 이용되는 저온 플라즈마는 저압으로 배기된 감압용기내에 특정의 가스를 봉입하고 전극 사이에 고전압을 인가함에 의하여 발생하는 것으로, 이러한 방전에는 불꽃방전, 코로나방전, 글로우방전등의 여러가지 형태의 것이 있지만, 이 중에서도 방전이 균일하여 활성화작용이 우수한 글로우방전이 특히 바람직하다. 본 발명에서 방전은 놋쇠전극을 사용하여, 방전조건은 섬유에의 균일한 플라즈마처리를 위해 방전전력 80W, 전류 35㎃, 전원주파수 5㎑, 인가전압 3∼5㎸로 하는 것이 바람직하다.The low temperature plasma used in the present invention is generated by enclosing a specific gas in a low pressure exhaust vessel and applying a high voltage between the electrodes. There are various types of discharges such as spark discharge, corona discharge, and glow discharge. Among them, a glow discharge having a uniform discharge and excellent activating action is particularly preferable. In the present invention, the discharge uses a brass electrode, and the discharge conditions are preferably set to a discharge power of 80 W, a current of 35 kW, a power supply frequency of 5 kW, and an applied voltage of 3 to 5 kW for uniform plasma treatment to the fibers.
본 발명에서 플라즈마처리시의 압력은 만약 진공으로 할 경우에는 과다한 투자비가 소요되며 균일하게 코드지가 주행할 때 진공이 걸리는 부분에서 떨림이 발생하고 과다한 표면 에칭으로 섬유물성이 저하될 우려가 있기 때문에 대기압으로 하는 것이 필요하다.In the present invention, the pressure during the plasma treatment requires excessive investment if the vacuum is used, and since the vibration occurs in the part where the vacuum is applied when the code paper runs uniformly, and there is a fear that the fiber property may be degraded due to excessive surface etching, the atmospheric pressure It is necessary to do
본 발명에서 이용가능한 특정의 가스로는 예를들면, 아르콘, 헬륨, 네온, 크립톤, 크세논, 라돈등의 불활성기체 및 아세톤 가스를 들 수 있는데, 이들 중에서도 특히 아르곤 가스와 아세톤 가스의 혼합가스가 바람직하다.Specific gases usable in the present invention include, for example, inert gases such as arcon, helium, neon, krypton, xenon, radon and acetone gas. Among these, a mixed gas of argon gas and acetone gas is particularly preferable. .
이 때 가스의 분위기 농도는 5∼50ppm인 것이 바람직하다. 가스의 분위기 농도가 상기 범위를 벗어나면 방전처리에 의한 표면개질이 잘 이루어지지 않아 본 발명이 목적으로 하는 접착력 향상의 효과를 수득할 수 없게 된다.At this time, the atmospheric concentration of the gas is preferably 5 to 50 ppm. If the atmospheric concentration of the gas is out of the above range, the surface modification by the discharge treatment is not made well, it is impossible to obtain the effect of improving the adhesive force of the present invention.
본 발명에서 저온 플라즈마처리시 방전판과 코드지 사이의 간격은 10∼100㎜인 것이 바람직하다. 방전판과 코드지 사이의 간격이 10㎜ 미만이면 방전판과 코드지간의 접촉에 의해 코드지가 손상될 우려가 있고, 그 간격이 100㎜를 초과하는 경우에는 섬유에 대한 플라즈마처리 효과가 미흡하게 되어 접착조성물과 섬유 사이의 접착력이 저하되므로, 본 발명에서 방전판과 코드지 사이의 간격은 상기 범위내인 것이 필수적이다.In the present invention, the spacing between the discharge plate and the cord paper during the low temperature plasma treatment is preferably 10 to 100 mm. If the distance between the discharge plate and the cord paper is less than 10 mm, the cord paper may be damaged by the contact between the discharge plate and the cord paper. If the distance exceeds 100 mm, the plasma treatment effect on the fibers is insufficient. Since the adhesive force between the adhesive composition and the fiber is lowered, in the present invention, it is essential that the gap between the discharge plate and the cord paper is within the above range.
본 발명에서 플라즈마처리시간은 인가전압과 섬유와 방전판과의 간격에 따라 결정되는데, 통상적으로 플라즈마처리는 60∼180초간 행하는 것이 바람직하다.In the present invention, the plasma treatment time is determined according to the applied voltage and the distance between the fiber and the discharge plate. In general, the plasma treatment is preferably performed for 60 to 180 seconds.

(3) 원소함량분석 :(3) Elemental Content Analysis:
율진제작소(일본) ESCA-850 장치를 사용하여 ESCA 분석을 실시하였다. C1S,O1S, N1S의 스펙트럼의 피크 면적에 의해 표면의 상대원소비를 구하고, O1S의 파형분석에 의해 구성된 화학조성의 상대치를 구하였다.Yuljin Corporation (Japan) ESCA-850 apparatus was used for ESCA analysis. The relative elemental ratios of the surfaces were determined by the peak areas of the spectra of C 1S , O 1S , and N 1S , and the relative values of the chemical composition formed by the waveform analysis of O 1S were obtained.
상기 표 1을 통해서 확인할 수 있는 바와 같이, 본 발명 방법에 따라 건조부에 의한 건조이전에 저온플라즈마처리를 행하면 물과의 접촉각은 감소되고 표면장력은 증가되며, O1S의 함량이 상대적으로 증가하고 -C-0-,-C(=O)O-의 비율이 증가되는 것으로 보아 전체적으로 소수성기가 친수성기로 변화되므로 용액에 대한 표면장력이 증가되어 결과적으로 접착력이 월등하게 향상되는 것을 확인할 수 있다. 더우기, 제 3도A 및 B에 도시된 전자현미경사진을 비교해보면 본 발명에 따라 플라즈마처리를 행할 경우 섬유표면에 돌기가 형성되어 접착면적이 증가하므로 그만큼 섬유와 라텍스 사이의 접착력이 향상되는 것을 확인할 수 있다. 이와 같이 섬유와 라텍스간의 접착력이 향상되면 최종 고무보강제품으로 만들 경우 섬유와 고무 사이의 접착력이 증가하여 박리현상이 발생하지 않으므로 내구성이 탁월한 고무보강제품용으로 이용될 수 있는 이점을 갖는다.As can be seen from Table 1, when the low-temperature plasma treatment before drying by the drying unit according to the present invention, the contact angle with water is reduced and the surface tension is increased, the content of O 1S is relatively increased As the ratio of -C-0-,-C (= O) O- is increased, the hydrophobic group is changed to a hydrophilic group as a whole, and thus the surface tension to the solution is increased, and as a result, the adhesion is significantly improved. Furthermore, when comparing the electron micrographs shown in FIGS. 3A and 3B, when plasma treatment was performed according to the present invention, protrusions were formed on the surface of the fiber, and thus the adhesion area was increased. Can be. When the adhesion between the fiber and the latex is improved as described above, when the final rubber reinforcement product is made, the adhesive force between the fiber and the rubber is increased, so that peeling does not occur.
