Abstract
본 발명은 고무접착력과 내식성이 우수한 아연도금 벨트코드의 제조방법에 관한 것이다.The present invention relates to a method for producing a galvanized belt cord excellent in rubber adhesion and corrosion resistance.
본 발명의 방법은 여러 가닥의 아연도금 선재를 연선하여 스트랜드를 만들고, 이 스트랜드들을 재 연선하여 벨트코드를 제조함에 있어서, 형부기와 연선 포이스 사이에 냉각방청제 공급 호스를 설치하여 휘발성 용제가 함유된 냉각방청제가 40∼90방울/분의 양으로 적하되어, 형부기를 통과하면서 부분 꼬임 상태로 되어 포이스로 인입되기전의 스트랜드 표면에 도포되도록 한 데에 기술적 특징이 있다.In the method of the present invention, strands are formed by stranding several strands of galvanized wire, and the strands are re-twisted to manufacture a belt cord. A cooling and anti-corrosive supply hose is installed between the molder and the stranded wire to contain a volatile solvent. The cooling rust inhibitor is added dropwise in an amount of 40 to 90 drops / minute, and is technically characterized in that it is applied to the surface of the strand before being introduced into the poise by being partially twisted while passing through the mold swelling.
상기와 같이 부분 꼬임 상태의 스트랜드들 표면에 도포된 냉각방청제는 포이스와 벨트코드 사이에서 발생하는 마찰열에 의하여 용제가 휘발하면서 벨트코드를 냉각시켜 아연 도금층의 소부현상을 방지하며, 벨트코드 표면에는 방청 피막만을 잔류시켜 고무와의 접착력과 내식성이 우수한 벨트코드의 제조가 가능하게 된다.As described above, the cooling anti-corrosive agent applied to the surface of the strands in the partially twisted state cools the belt cord while the solvent is volatilized by frictional heat generated between the force and the belt cord, thereby preventing the galvanization of the galvanized layer. By leaving only the coating, it becomes possible to manufacture a belt cord having excellent adhesion to rubber and corrosion resistance.
본 발명의 방법에 사용되는 냉각방청제는 휘발성이 우수한 용제 90∼99wt%에 용제 가용성 수지 1∼10wt%를 용해하고, 이 용액에 0.1∼10g/l의 트리아진티올 유도체를 첨가하고 수소이온농도를 7이상으로 하여 만들며, 수지를 사용하지 않을 경우에는 트리아진티올 유도체를 무수 알코올류에 용해하여 사용한다. 단, 이때 사용하는 알코올류는 탄소의 수가 2개 이상인 것을 사용하는 것이 바람직하다.The cooling rust inhibitor used in the method of the present invention dissolves 1 to 10 wt% of a solvent soluble resin in 90 to 99 wt% of a highly volatile solvent, and adds 0.1 to 10 g / l triazine thiol derivative to the solution to increase the hydrogen ion concentration. If the resin is not used, triazine thiol derivative is dissolved in anhydrous alcohols. However, it is preferable that the alcohol used at this time uses the thing of two or more carbon numbers.
상기의 냉각방청제는 물이 완전히 배제된 것으로서, 압축공기로 포이스와 성형 중인 벨트코드를 냉각시켰던 종래의 방법과 달리 제조된 벨트코드의 보관시 수분에 의한 백청 발생을 억제하는 잇점도 있다.The cooling rust inhibitor is completely excluded from water, and has the advantage of suppressing the occurrence of white rust due to moisture when the belt cord is manufactured, unlike the conventional method of cooling the poise and the belt cord being molded by compressed air.
Description
본 발명은 고무접착성과 내식성이 우수한 아연도금 벨트코드의 제조방법에 관한 것으로서, 더 자세하게는 동일한 선경의 여러 소선들이 연선·결합된 스트랜드(strand)들을 다시 꼬아 벨트코드를 제조하는 연선공정에서 스트랜드들이 포이스 (poise)를 통과할 때, 스트랜드 아연 도금층의 마찰열에 의한 소부현상을 방지하기 위하여 포이스 입구에서 냉각제 역할을 하는 트리아진티올 유도체가 함유된 휘발성이 우수한 냉각방청체를 스트랜드에 도포하므로써 냉각방청제에 함유된 용제의 휘발에 의하여 포이스를 통과시 스트랜드의 충분한 냉각 효과가 얻어져 아연 도금층의 소부현상이 방지되면서 우수한 고무접착력과 백청 방지 특성을 갖도록 한 벨트코드에 관한 것이다.The present invention relates to a method for manufacturing a galvanized belt cord having excellent rubber adhesiveness and corrosion resistance, and more particularly, strands in a twisted pair process of twisting strands and strands of the same wire diameter twisted together to produce a belt cord. When passing through the poise, the strands are cooled by applying a highly volatile cooling rust preventive containing triazinethiol derivative which acts as a coolant at the inlet of the strand to prevent frictional burns caused by the heat of friction. The present invention relates to a belt cord having excellent rubber adhesiveness and anti-whitening characteristics while being able to obtain sufficient cooling effect of strands when passing through a poise by volatilization of a solvent contained in a rust preventive agent.
일반적으로 콘베이어 벨트 등에 사용되는 벨트코드는 아연도금된 선재를 필요한 선경으로 신선한 후 연선하여 스트랜드를 만들고, 이 스트랜드들을 다시 연선하여 제조된다.In general, belt cords used in conveyor belts are made of stranded wire after freshly galvanized wire rod to the required diameter, and the strands are manufactured by stranding the strands again.
이때, 상기의 연선공정에서 스트랜드 아연 도금층의 소부현상 방지와 벨트코드를 고무와 접착시키전까지 고무접착력에 악영향을 미치는 아연 도금층의 백청이 발생되지 않도록 하는 것이 벨트코드 제조의 핵심 사항이 된다.In this case, the core matter of the belt cord manufacturing is to prevent the burning of the strand zinc plated layer and prevent the white blue of the zinc plated layer from adversely affecting the rubber adhesion force until the belt cord is bonded with the rubber in the stranded wire process.
스트랜드들을 연선시, 스트랜드들은 포이스를 통과하게 되며, 이때 발생하는 스트랜들과 포이스 간의 마찰열에 의한 스트랜드 아연 도금층의 소부현상을 방지하기 위하여 압축공기를 불어 넣어 스트랜드들과 포이스를 냉각하여 왔으나, 압축공기에 의한 냉각으로는 아연 도금층의 소부현상을 완전히 방지할 수가 없다.When strands are stranded, the strands pass through the poise. The strands and the poise have been cooled by blowing compressed air to prevent quenching of the galvanized layer due to frictional heat between the strands and the poise. However, cooling by compressed air does not completely prevent quenching of the galvanized layer.
또한, 압축공기에는 미량의 응축 수분이 잔류하고 있고, 때로는 미세한 기름 성분까지도 함유되는 바, 이러한 수분과 기름이 벨트코드의 보관시 백청 발생과 표면 오염에 의한 고무접착력 저하 요인으로 작용하게 된다.In addition, a small amount of condensed water is left in the compressed air, and sometimes even a fine oil component is contained. This moisture and oil act as a factor of reducing rubber adhesion due to white rust and surface contamination when the belt cord is stored.
그리고, 벨트코드는 그 특성상, 코드를 구성하는 스트랜드들에 수분이나 기름 성분이 잔존하게 되면 백청이 발생하여 고무와의 접착력에 악영향을 미치게 되므로 이를 방지하기 위하여 초음파 세척을 하거나 크로메이트 처리를 할 수 있으나, 특히 크로메이트 처리는 환경오염 문제와 고무접착력을 떨어뜨리는 문제가 있다.In addition, the belt cord may have an ultrasonic effect or chromate treatment in order to prevent it because white rust is generated when water or oil remains on the strands constituting the cord, which adversely affects adhesion to rubber. In particular, chromate treatment has problems of environmental pollution and rubber adhesion.
다른 백청 발생 방지 방법으로는, 일본 특허공개 공보 평8-239776에 물의 분산성을 이용하여 황화물 이온이 아연과 반응하여 안정된 황화아연(ZnS) 피막을 형성시키는 방법이, 동 평8-67834에는 황화물과 수용성 수지의 혼합 수용액으로 코팅하는 방법이 개시되어 있다.As another method for preventing the occurrence of white rust, Japanese Patent Laid-Open Publication No. Hei 8-239776 uses a dispersibility of water to form sulfide ions with zinc to form a stable zinc sulfide (ZnS) film. A method of coating with a mixed aqueous solution of a water-soluble resin is disclosed.
그리고, 국내 특허공개 공보 1998-073309에는 수용성 수지와 물을 주성분으로 하는 조성물에 트리아진티올 화합물 및 인산 이온을 함유시킨 수용성 방청제가 알려져 있다.Also, Korean Patent Publication No. 1998-073309 discloses a water-soluble rust preventive agent comprising a triazine thiol compound and phosphate ions in a composition containing water-soluble resin and water as main components.
그러나, 상기의 방청 방법들은 수용성이거나 물을 주성분으로 하므로, 도포 후 강선과 강선, 스트랜드와 스트랜드 사이에 침투된 수지와 물의 영향으로 벨트코드를 권취한 보빈의 내측은 건조가 완전하지 않아 표면 얼룩을 발생시키고 잔류하는 수분은 고무접착력에 악영향을 미치게 되는 등의 단점이 있다.However, since the above rust-preventing methods are water-soluble or mainly composed of water, the inside of the bobbin wound around the belt cord due to the influence of resin and water penetrated between the steel wire and the steel wire, the strand and the strand after application is not completely dried, and thus stains the surface. Water generated and remaining has a disadvantage such as adversely affect the rubber adhesive force.
그리고, 황화수소 가스 또는 그것을 용해시킨 수용액을 이용하는 것은, 금속 표면에 황화물 형성시 발생하는 인체에 유해한 황화수소 가스 배출 때문에 쉽지가 않다.In addition, the use of hydrogen sulfide gas or an aqueous solution in which it is dissolved is not easy due to the release of hydrogen sulfide gas harmful to the human body generated when sulfides are formed on the metal surface.
본 발명은 벨트코드 제조시 오히려 수분 공급원으로서의 역활을 하게되는 냉각용 압축공기의 사용을 배제하고, 스트랜드들과 포이스에서 발생하는 마찰열을 이용하기 위하여 열에 의해 쉽게 증발하는 휘발성 용제에 고무와의 접착력을 향상시켜 주는 방청피막 코팅제를 혼합사용하므로써, 코팅제를 용해한 휘발성 용제 성분을 포이스 통과시의 냉각제로서 이용하고 벨트코드를 구성하는 강선의 아연 도금층 표면에 고무접착력과 내식성이 우수한 안정된 피막을 형성시킬 수 있는 코팅방법을 제공하는 데에 본 발명의 목적이 있다.The present invention eliminates the use of compressed air for cooling, which acts as a water source, rather than producing belt cords, and adheres to rubber to volatile solvents that easily evaporate by heat to utilize frictional heat generated from strands and poises. By using the anti-corrosive coating agent to improve the efficiency, the volatile solvent component in which the coating agent is dissolved is used as a coolant when passing through the poise, and a stable film having excellent rubber adhesion and corrosion resistance can be formed on the surface of the galvanized layer of the steel wire constituting the belt cord. It is an object of the present invention to provide a coating method that can be.

본 발명의 고무접착성과 내식성이 우수한 벨트코드의 제조방법은 스트랜드가 연선 포이스로 들어가기 직전에 고무접착성과 내식성 및 휘발성이 있는 본 발명 특유의 성분 조성으로 구성된 냉각방청제를, 적절한 양만큼 반 꼬임 상태의 스트랜드들 표면에 도포함에 기술적 요지를 두고 있는 것으로, 이때 사용되는 냉각방청제는 용제 가용성수지 1∼10wt%를 용제 90∼99wt%에 용해시킨 후, 이 용액에 트리아진티올 유도체를 0.1∼10g/l 첨가하고 수소이온농도를 7이상으로 하여 조성한 용액이며, 수지를 사용할 수 없을 경우에는 무수 알코올 용제에 트리아진 유도체를 0.1∼10g/l함유시켜 사용할 수도 있다.The belt cord manufacturing method of the present invention has excellent rubber adhesiveness and corrosion resistance, and the anticorrosive cooling anticorrosive agent composed of the unique ingredient composition of the present invention, which has rubber adhesiveness, corrosion resistance and volatility just before the strand enters the stranded wire, The technical essence is to apply to the surface of the strands. The cooling rust inhibitor used here is dissolved 1 to 10 wt% of solvent soluble resin in 90 to 99 wt% of solvent, and then 0.1 to 10 g / l of triazine thiol derivative in the solution. It is a solution which is added and has a hydrogen ion concentration of 7 or more, and when a resin cannot be used, it can also be used by containing 0.1-10 g / l of triazine derivative in anhydrous alcohol solvent.
본 발명은, 상기의 냉각방청제를 포이스 인입 직전의 스트랜드들 표면 위에 적하·도포시키므로써 포이스 통과시 발생하는 마찰열에 의하여 벨트코드 표면에 도포된 냉각방청제의 용제 성분만이 휘발하면서 포이스와 코드를 냉각시키고, 포이스를 통과하며 제조된 벨트코드의 표면에는 수지 성분의 방청제만을 잔류시켜 고무접착성과 내식성이 우수한 벨트코드를 제조하는 방법에 관한 것이다.According to the present invention, by dropping and applying the cooling rust inhibitor on the surface of the strands immediately before the introduction of the force, only the solvent component of the cooling rust agent applied to the belt cord surface by the frictional heat generated during the passage of the pore is evaporated. The present invention relates to a method of manufacturing a belt cord having excellent rubber adhesiveness and corrosion resistance by cooling the resin, passing through the pore, and leaving only a rust inhibitor of a resin component on the surface of the belt cord.
상기의 냉각방청제에 사용되는 용제 가용성 수지로는 쿠마론 수지가 좋으며, 이를 용해시키기 위한 용제로는 벤질 알코올, 염소화 용제, 에스텔류, 케톤류 및 석유계 용제가 좋고 특히 석유납사 또는 비티엑스(B.T.X.) 등이 바람직 하다.The solvent soluble resin used in the cooling rust preventive agent is a coumarone resin, and the solvent for dissolving it is preferably benzyl alcohol, chlorinated solvents, esters, ketones and petroleum solvents, in particular petroleum naphtha or BTX Etc. are preferable.
그리고, 수지를 사용하지 않을 경우에는 트리아진티올 유도체를 용해시켜 사용하는 용제로는 무수 알코올류를 이용하고 알코올류는 탄소의 수가 2개 이상인 것, 특히 무수 에탄올 또는 무수 푸로판올 등이 사용될 수 있다.In the case of not using a resin, anhydrous alcohols may be used as a solvent for dissolving the triazine thiol derivative, and alcohols may have two or more carbon atoms, in particular anhydrous ethanol or anhydrous furopanol. .
용제 가용성 수지와 용제의 배합 비율은 수지 1∼10wt%, 용제 90∼99wt%이다. 이때, 수지 함량이 1wt% 미만이고 용제가 99wt%를 초과하면 방청성분의 피막 두께가 불균일하게 되어 방청력의 부족과 벨트코드와 고무와의 접착력이 큰 편차를 갖게되며, 수지가 10wt%를 초과하고 용제가 90wt% 미만이면 수지 피막이 필요 이상으로 두꺼워져 고무와의 접착력이 오히려 감소하게 된다.The compounding ratio of solvent-soluble resin and a solvent is 1-10 wt% of resin, and 90-99 wt% of solvent. At this time, if the resin content is less than 1wt% and the solvent exceeds 99wt%, the film thickness of the rust preventive component becomes nonuniform, resulting in a lack of rust preventive power and a great deviation in adhesion between the belt cord and rubber, and resin exceeding 10wt%. If the solvent is less than 90wt%, the resin film becomes thicker than necessary, so that the adhesive strength with the rubber is rather reduced.
수지 피막의 코팅이 부적합할 경우에는 무수 알코올에 트리아진티올을0.1∼10g/l 용해시킨 용액을 벨트코드 제조시 연선 포이스 입구에서 적하시켜 피복하며, 트리아진티올 유도체는 1,3,5-트리아진-2,4,6-트리티올.모노나트륨염 등을 사용하고 물의 사용은 절대 배제하여야 한다.If the coating of the resin film is inadequate, a solution of 0.1 to 10 g / l of triazine thiol dissolved in anhydrous alcohol is added dropwise at the inlet of the stranded wire to prepare the belt cord, and the triazine thiol derivative is 1,3,5- Triazine-2,4,6-tritriol, monosodium salt, etc. should be used and the use of water should never be excluded.
상기 두 가지의 냉각방청체의 도포 방법은 연선 포이스 입구에서 직접 적하하는 것이 바람직하며, 도포된 냉각방청제는 포이스 통과시 발생하는 마찰열에 의해서 함유된 휘발성 용제만을 잃고 방청제만 벨트코드에 잔류하게 된다.The application of the two cooling rust preventers is preferably carried out directly at the inlet of the stranded wire, and the applied cooling rust prevents only the volatile solvent contained by the frictional heat generated during the passage of the force and only the rust preventive agent remains on the belt cord. do.
이때, 냉각방청제의 적하량은 40∼90방울(drops)/분 정도가 바람직하다. 적하량이 40방울/분 미만이면 냉각능력 부족으로 아연 도금층의 소부현상이 발생하여 벨트코드 표면에 얼룩이 생기며, 적하량이 90방울/분을 초과하면 용제의 휘발이 불충분하여 건조된 방청 피막을 형성시키기 어려워 보빈에 감겨진 벨트코드의 표면에 역시 얼룩이 생겨 외관을 해치고 고무와의 접착력에 좋지 않은 영향을 미친다.At this time, the dropping amount of the cooling rust inhibitor is preferably about 40 to 90 drops / minute. If the dripping amount is less than 40 drops / minute, the galvanized layer will be burned due to lack of cooling capacity, and the surface of the belt cord will be stained. If the dripping amount exceeds 90 drops / minute, the volatilization of the solvent will be insufficient, making it difficult to form a dried rustproof film. The surface of the belt cord wound on the bobbin will also stain the appearance and damage the appearance and adversely affect the adhesion to rubber.
본 발명 고무접착력과 내식성이 우수한 벨트코드 제조방법의 상기 기술적 구성과 구체적인 작용효과에 대한 자세한 사항은 본 발명의 바람직한 실시예를 도시하고 있는 도면을 참조한 아래의 설명에 의하여 명확하게 이해될 것이다.Details of the technical configuration and specific effects of the belt cord manufacturing method excellent rubber adhesion and corrosion resistance of the present invention will be clearly understood by the following description with reference to the drawings showing a preferred embodiment of the present invention.
도1은 본 발명의 방법을 수행하는데 적합한 벨트코드 제조장치의 개략 구조를 보인 정면도로서 이에 도시된 바와같이, 아연도금된 스트랜드(2)가 감긴 보빈(3)을 원통형의 쉘(6)(shell) 내에 설치되어 있는 플라이어(5)(flyer)에 장착시키고 보빈(3)에 부착되어 있는 브레이크(4)로써 스트랜드(2)의 장력을 조정한다.1 is a front view showing a schematic structure of a belt cord manufacturing apparatus suitable for carrying out the method of the present invention. As shown therein, a bobbin 3 wound with a galvanized strand 2 is formed into a cylindrical shell 6. The tension of the strands 2 is adjusted with the brakes 4 attached to the bobbin 3 and mounted on the pliers 5 installed therein.
장력 조정이 완료된 스트랜드(2)를 쉘(6)내에 배선한 후, 형부기(7), 포이스(10), 인출 캡스탄(14) 및 면포 받침대(12)를 거쳐 권취기(13)에 고정시키므로써 벨트코드 제조를 위한 준비 과정이 끝나게 된다.After the strands 2 of which tension has been adjusted are wired into the shell 6, they are connected to the winding machine 13 through the mold-splitting machine 7, the force 10, the drawing capstan 14, and the cotton cloth pedestal 12. By fixing, the preparation process for the belt cord manufacturing is completed.
상기와 같이 스트랜드(2)의 장착이 완료된 후, 인출 캡스탄(14)이 스트랜드를 당겨주는 것과 동시에 구동 모터(1)에 의하여 쉘(6)을 회전시키게 되면 스트랜드(2)들이 형부기(7)에서 1차 꼬여지고 포이스(10)를 통과하면서 완전한 꼬임 형태로 연선된다.After the mounting of the strands 2 is completed as described above, when the withdrawal capstan 14 pulls the strands and at the same time rotates the shell 6 by the drive motor 1, the strands 2 form the mold swelling machine 7. 1) twisted and twisted in a complete twisted form through the force (10).
이때, 냉각방청제 공급통(9)에 들어 있는 냉각방청제는 가는 호스(8)를 통하여 형부기(7)와 포이스(10) 사이를 지나는 반 성형 상태의 벨트코드(15) 표면 위로 적하되고, 포이스(10)를 통과하면서 휘발성분이 제거되어 방청제 피막이 형성된 벨트코드(11)의 제조가 이루어지게 된다.At this time, the cooling rust inhibitor contained in the cooling rust inhibitor supply cylinder 9 is dropped onto the surface of the belt cord 15 in the semi-molded state passing between the mold-keeping machine 7 and the pore 10 through the thin hose 8, As the volatiles are removed while passing through the pois 10, the belt cord 11 having the anti-rust film formed thereon is manufactured.
본 발명의 실시예로써, 상기와 같은 방법을 적용하여 선경이 0.62mm인 아연도금 선재를사용하고 냉각방청처리 방법을 달리하여 7 ×7구조의 직경 5.6mm 되는 벨트코드를 제조하였고, 각 시편에 대하여 고무와의 접착성, 내식성 및 표면 외관 상태를 평가한 결과는 다음 표1과 같다.As an embodiment of the present invention, a belt cord having a diameter of 5.6 mm of 7 x 7 structure was manufactured by using a galvanized wire having a diameter of 0.62 mm and applying a cooling rust treatment method by applying the above-described method. The results of evaluating the adhesiveness, corrosion resistance and surface appearance state with respect to rubber are shown in Table 1 below.
* Ｏ : 양호(무색투명), △ : 광택상실 및 약간 변색,* O: good (colorless and transparent), △: loss of gloss and slight discoloration,
×: 소부현상 발생 및 변색 심함×: occurrence of swelling phenomenon and severe discoloration
표1에서 고무접착력은 50L ×65W ×20D되는 가류몰드에 고무 콤파운드와 벨트코드를 넣고 가류온도 150℃, 압력 520 psi에서 53분간 가류하였으며, 상온에서 24시간 경과 후 인장시험기에서 벨트코드가 고무에서 이탈되는 힘을 측정하였다.In Table 1, the rubber adhesive force is 50L × 65W × 20D and the rubber compound and the belt cord are put in a vulcanization mold and vulcanized for 53 minutes at a vulcanization temperature of 150 ℃ and a pressure of 520 psi. After 24 hours at room temperature, the belt cord is The force that was released was measured.
그리고, 염수분무시험은 JIS Z-2371에 준하여 실시하고 48시간 후 백청 발생정도를 5점 만점으로 하여 평가하였다. 즉, 백청발생이 없으면 0점, 20%이하이면 1점, 20%초과 40%이하이면 2점, 40%초과 60%이하이면 3점, 60%초과 80%이하이면 4점, 80%를 초과하면 5점으로 평가하였다.The salt spray test was carried out according to JIS Z-2371 and evaluated after 48 hours with the degree of white rust generated as a perfect score of 5 points. That is, if there is no white rust, it is 0, 20% or less, 1 point, 20% or more, 40% or less, 2 points, 40% or more, 60% or less, 3 points, 60% or more, 80% or less, 4 points, 80% or more 5 points were evaluated.
상기의 실시예에서 사용한 수지는 석유계 용제에 쿠마론 수지를 사용하였고, 수지용액의 첨가 성분은 1,3,5-트리아진-2,4,6-트리티올.모노나트륨이며, 냉각방청제의 적하량은 공히 50∼60방울/분으로 하였다.As the resin used in the above examples, comarone resin was used as the petroleum solvent, and the additive component of the resin solution was 1,3,5-triazine-2,4,6-tritriol.mono-sodium. The dripping amount was 50 to 60 drops / minute.
상기 표1에서 알 수 있듯이 압축공기를 사용한 비교1은 냉각효과가 거의 없기 때문에 소부현상을 방지할 수가 없으며, 따라서 고무접착력 역시 가장 낮은 값을 보여 주고 있다.As can be seen in Table 1, the comparison 1 using compressed air is hardly prevented from quenching because there is little cooling effect, and thus the rubber adhesive force also shows the lowest value.
그리고, 비교2는 무수 에탄올을 사용함에따라 소부현상은 다소 억제되었으나 수지성분이 없는 용제만을 도포한 바, 여전히 고무접착력이 낮은 값을 갖는다.In comparison 2, the baking effect was somewhat suppressed by the use of anhydrous ethanol, but only the solvent having no resin component was applied, and thus the rubber adhesive force was low.
이상의 시험 결과에서 살펴본 바와 같이, 본 발명의 벨트코드는 비교예의 샘플과 달리 휘발성 용제와 벨트코드 표면에 형성된 수지피막때문에 포이스 통과시 표면 아연층의 열열화가 감소하여 아연층의 안정성이 유지되고, 그 위에 수지피막이 추가 피복되므로써 종래 비교예의 벨트코드 대비 월등한 고무접착력과 내식성을 갖게 되는 것이다.As seen from the above test results, the belt cord of the present invention, unlike the sample of the comparative example, due to the resin film formed on the surface of the volatile solvent and the belt cord is reduced thermal degradation of the surface zinc layer during the passage of the pore to maintain the stability of the zinc layer, The resin coating is further coated thereon to have superior rubber adhesion and corrosion resistance compared to the belt cord of the conventional comparative example.
이상에서 살펴본 바와 같이, 본 발명의 방법은 물이 완전히 배제되고 휘발성이 강한 용제를 매개로한 냉각방청제를 사용하므로써, 습기에 의한 아연 도금층의 백청과 포이스에서 발생하는 마찰열에 의한 아연 도금층의 소부현상을 효과적으로 방지해주는 잇점이 있다.As described above, in the method of the present invention, by using a cooling rust inhibitor through a solvent that is completely excluded from water and highly volatile, the baking of the zinc plating layer due to frictional heat generated in the white rust and the poise of the zinc plating layer due to moisture There is an advantage that effectively prevents the phenomenon.
또한, 벨트코드 표면에 잔류하는 수지 피막은 고무와의 접착력을 높여줄 뿐아니라 벨트코드의 표면 외관도 개선해주는 효과가 있다.In addition, the resin film remaining on the surface of the belt cord not only increases the adhesive strength with the rubber, but also improves the surface appearance of the belt cord.
