[발명의 상세한 설명]Detailed description of the invention

본 발명은 자동차용 타이어 측벽에의 이색(異色) 마킹(Marking) 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of dichroic marking on tire sidewalls for automobiles.

타이어의 측벽에 마킹을 하는 방법으로서는 타이어 가류금형에 마킹플레이트를 설치하므로서 마킹플레이트의 형상에 따라 타이어에 요철부가 형성되게 하거나(공개특허공고 84-6936, 본인의 실용신안출원 92-21385), 타이어 측벽에 백색고무를 식입(植入)하므로서 마킹을 하는 방법이 알려져 있다.As a method of marking on the side wall of the tire, by installing the marking plate on the tire vulcanization mold, the uneven portion is formed in the tire according to the shape of the marking plate (Publication Publication No. 84-6936, Applicable Utility Model Application 92-21385), or tire Background Art A method of marking by injecting white rubber into a sidewall is known.

본 발명은 특히 타이어 측벽에 백색 또는 이색 마킹을 하는 새로운 방법을 제공하므로서, 백색고무를 식입하여 백색마킹을 수행하는 종래의 타이어에 있어서의 크나큰 불편과 비경제성 및 타이어 안전상의 결점을 제거하기 위한 것이다. 타이어 측벽에 백색고무를 식입하여 마킹하는 종래의 방법은 그 공정이 복잡하여 많은 제조비용을 소요하는 결점이 있으며 타이어 측벽의 재질에 있어서의 균질성(Uniformity)를 상실케하여 품질에 부정적 영향을 부여할 우려가 있었다.The present invention provides a new method of white or dichroic marking on tire sidewalls, in particular, to eliminate significant inconveniences, inconsistencies and tire safety drawbacks in conventional tires incorporating white rubber to perform white marking. . The conventional method of injecting and marking white rubber into the tire sidewall has a drawback in that the process is complicated and requires a lot of manufacturing cost, and it has a negative effect on the quality by losing uniformity in the material of the tire sidewall. There was concern.

즉, 타이어 측벽에 백색고무를 식입하여 백색마킹을 형성시키기 위하여는 타이어의 측벽(Side wall)부재 압출성형시 측벽의 백색마킹 설치해당 부위에 백색고무 조성물을 동시에 압출시켜 타이어의 측벽용 고무판을 형성시킨후 그위에 피복층을 형성시키고 이를 이용하여 그린타이어를 제조하고, 이와 같이 하여 제조된 그린타이어의 백색고무 부분이 가류용 금형의 마킹플레이트 설치부위와 일치되게 가류용 금형에 그린타이어를 장입시키고, 이어서 그린타이어를 가류하게되면 백색마킹 부위 표면에 흑색의 고무 피복층이 얇게 피복되어 있으므로 흑색 피복층을 갈아 내어(Buffing) 백색문자가 표출되게 하여야 하는 복잡하고도 어려운 공정을 필요로 하게된다. 뿐만 아니라 이와 같이 하여 제조된 타이어는 측벽에 이질적인 백색고무 조성물이 매입되어 있어 타이어의 균질성(Uniformity)이 파괴되어 고속주행시의 안전성을 저해하며, 타이어의 판매전까지 백색마킹부위가 오염되지 아니하도록 보호막을 입혀야 하며,타이어의 일부에 돌출부가 형성되어 있어 다른 쪽과의 중량차가 발생되어 불균형의 문제가 발생하는 등의 결점이 있었던 것이다.That is, in order to form white marking by injecting white rubber into the side wall of the tire, the white marking installation of the side wall member during molding of the side wall member of the tire is performed. After forming a coating layer thereon to produce a green tire using the same, and the green rubber is charged to the vulcanization mold so that the white rubber portion of the green tire manufactured in this way coincides with the marking plate installation part of the vulcanization mold. Subsequently, when the green tire is vulcanized, a black rubber coating layer is thinly coated on the surface of the white marking part, thus requiring a complicated and difficult process of grinding the black coating layer to allow white characters to be displayed. In addition, the tire manufactured in this way is embedded with a heterogeneous white rubber composition on the side wall, which destroys the uniformity of the tire, impairing safety during high-speed driving, and protecting the white marking area from being contaminated until the tire is sold. It has to be coated, and a part of the tire is formed with a protrusion, such that a weight difference with the other side occurs, resulting in a problem of unbalance.

그리고 바코드가 표시된 라벨기재, 내열성수지로된 투명보호막, 열경화성수지로된 정착제층 및 이형지로 구성된 바코드 라벨을 그린적소에 부착시키는 기술이 일본국 공개특허공고 소60-187539호로 알려진바 있으나, 이는 완성전의 그린타이어에의 바코드설치에 관한 기술이어서 본 발명의 목적을 달성할 수 없으며 바코드가 표시된 라벨기재는 타이어의 고무와 신축성이 달라 이를 타이어의 마킹과 같이 광범위하게 또 다수의 곳에 설치하는 것이 적합치 아니하며 마킹수단으로 이용될 수 있는바 아니다.In addition, a technique of attaching a bar code label composed of a label base material on which a bar code is displayed, a transparent protective film made of a heat resistant resin, a fixing layer made of a thermosetting resin, and a release paper to a green place has been known as Japanese Patent Application Publication No. 60-187539. Previously, the technology of the bar code installation on the green tire can not achieve the object of the present invention, the bar code label label material is different from the rubber and elasticity of the tire, it is not suitable to be installed in a wide range and many places, such as the marking of the tire It can not be used as a marking means.

이에 본 발명은 타이어 측벽에 마커(Marker)를 형성시킴에 있어서종래와 같이 조성이 다른 이질의 고무를 식입치 아니하고 완성된 타이어의 측벽 표면에 얇은 마커를 부착하므로서 소기의 마킹 목적을 달성할 수 있도록 한 것이다.Therefore, in the present invention, a marker is formed on the sidewall of a tire, and thus, a thin marker is attached to the sidewall surface of the finished tire without injecting heterogeneous rubber having a different composition as conventionally, so as to achieve a desired marking purpose. It is.

즉, 본 발명은 이형지에 반사층을 가진 본체로 구성된 마커를 부착시킨후 마커 본체를 가류형성된 타이어의 임의 부위에 접합시키므로서 종래와 같이 복잡하고 어려운 제조공정을 생략하고 금형의 제조비용마저 절감하며, 마킹의 효과가 탁월할 뿐아니라 마킹을 임의로 교체 수선할 수 있게 하였는바, 이와 같은 본 발명을 첨부된 도면에 의하여 설명하면 다음과 같다.That is, the present invention by attaching a marker consisting of a main body having a reflective layer on the release paper and then bonding the marker main body to any part of the vulcanized tire, eliminating the complicated and difficult manufacturing process as in the prior art, and reduces the manufacturing cost of the mold, Not only is the effect of the marking excellent, but also allows the marking to be arbitrarily replaced and repaired. The present invention will be described with reference to the accompanying drawings as follows.

본 발명은 형광, 축광안료를 부가하여 특히 야간에 있어서의 반사효과를 극대화시킬 수 있는바, 이와 같은 실시예가 제2도의 (가)에 도시되어 있다.The present invention can maximize the reflection effect, especially at night by the addition of fluorescence, phosphorescent pigments, such an embodiment is shown in (a) of FIG.

즉, 합성수지 필름으로 형성된 이형지(1)에 UV보호막(2), 폴리우레탄 접착층(3), 축광안료층(4), 폴리우레탄접착층(5), 축광안료층(6), 백색안료층(7) 및 접착제층(8)을 차례로 형성시킨다.That is, the UV protective film 2, the polyurethane adhesive layer 3, the phosphorescent pigment layer 4, the polyurethane adhesive layer 5, the phosphorescent pigment layer 6, and the white pigment layer 7 on the release paper 1 formed of a synthetic resin film. ) And the adhesive layer 8 are formed in turn.

UV보호막(2)과 축광안료층(4) 사이에 폴리우레탄접착층(3,5)을 개재시키는 것은,축광안료의 입자가 비교적 크므로 안료입자와 UV보호막(2)간의 접착사태가 불량하여 타이어가 굴신작용을 할때에 균일이 생기는 것을 방지하기 위함이다.The polyurethane adhesive layers 3 and 5 are interposed between the UV protective film 2 and the phosphorescent pigment layer 4 because the particles of the photoluminescent pigment are relatively large and the adhesion between the pigment particles and the UV protective film 2 is poor. This is to prevent the formation of uniformity when flexing.

축광안료층(4)는 폴리우레탄 올리고머(Polyurethane Oligomer) 100부량(중량비 : 이하같음)에 녹색축광안료 100부량 및 형광 안료인 TOB 10부량 및 RF 5부량을 혼합하여 형성시킨다. RF는 Resorcinol Formaldehyed Resin을 의미하며, 이는 상품명 Penacolite Resin으로 거래되고 있다. 또한 RF는 -NCO기가 있어서 폴리우레탄 올리고머의 -OH Radial과 결합(Crosslinking)하여 경화시키는 역활을 한다. 백색안료층은 타이어의 흑색 바탕이 투시됨을 방지하여 축광안료의 시각효과를 증진시키게 한다The phosphorescent pigment layer 4 is formed by mixing 100 parts by weight of a polyurethane oligomer (weight ratio: equal to or less) with 100 parts of green photoluminescent pigment, 10 parts of TOB and 5 parts of RF, which are fluorescent pigments. RF stands for Resorcinol Formaldehyed Resin, which is traded under the trade name Penacolite Resin. In addition, RF has a -NCO group and serves to cure by crosslinking with -OH Radial of the polyurethane oligomer. The white pigment layer prevents the black background of the tire from seeing and enhances the visual effect of the phosphorescent pigment.

이와 같이 축광, 형광안료를 부가한 실시예외에 일반적인 백색마킹 방법에 사용될 수 있는 또다른 실시예가 제2도의 (나)에 도시되어 있다.Thus, another embodiment that can be used in the general white marking method besides the embodiment in which the photoluminescent and fluorescent pigments are added is shown in FIG. 2B.

즉, 합성수지 필름으로 형성된 이형지(1)에 UV보호막(2), 백색안료층(7), UV보호막(21) 및 접착제층(8)을 형성 시킨다.That is, the UV protective film 2, the white pigment layer 7, the UV protective film 21 and the adhesive layer 8 are formed on the release paper 1 formed of a synthetic resin film.

여기에 있어서의 백색안료층(7)은 폴리우레탄 올리고머 100부량에 백색안료인 TiO2100부량, 형광안료인TOB 10부량 및 RF 5부량을 혼가하여 형성시키는 것이 바람직하다. 여기에서 백색안료인 산화티타늄(TiO2)는 입자가 작기 깨문에 상기의 실시예에 있어서의 경우와 같이 폴리우레탄 접착층을 개재시킬 필요가 없다.The white pigment layer 7 is preferably formed by mixing 100 parts by weight of a polyurethane oligomer with 100 parts by weight of TiO 2 as a white pigment, 10 parts by weight of TOB as a fluorescent pigment, and 5 parts by weight of RF. Here, titanium oxide (TiO 2 ), which is a white pigment, does not need to be interposed with a polyurethane adhesive layer as in the above embodiment because of the small particle size.

이와 같이 형성된 제 2 도의 (가)와 (나)의 전사지는 이를 타이어 측벽(9)의 임의 위치에 부착할 수 있다.The transfer papers of (a) and (b) of FIG. 2 thus formed may be attached to any position of the tire side wall 9.

본 발명의 전사지를 타이어에 부착하는 방법은 다음과 같다.The method of attaching the transfer paper of the present invention to a tire is as follows.

타이어 측벽(9)의 마킹부위를 프라이머(Primer)를 도포한다. 프라이머는 희석제(thinner)에 D-PLYCOTY Powder를 2%(wt) 섞은 것이며, 1,3,5-Chlorosulfuric-iso-cyanurate의 화학구조, 즉, 강산 radial이 있어서 가류표면을 부식시켜 전사지와의 접착을 향상시켜주는 역활을 한다.A marking portion of the tire side wall 9 is coated with a primer. The primer is a thinner mixed with 2% (wt) of D-PLYCOTY Powder, and has a chemical structure of 1,3,5-Chlorosulfuric-iso-cyanurate, that is, a strong acid radial that corrodes the vulcanized surface and adheres to the transfer paper. Play a role in improving

Primer에는 RF를 20%정도 첨가하여 접착제와의 접착력을 향상 시킬 수 있다. 그리고 전사지의 접착제층에 용제(MEX ; RF=2 : 1)를 도포하여 접착제층과 프라이머를 도포시킨 타이어 표면과의 접착을 유도한다.Primer can improve the adhesion with adhesive by adding 20% RF. Then, a solvent (MEX; RF = 2: 1) is applied to the adhesive layer of the transfer paper to induce adhesion between the adhesive layer and the tire surface on which the primer is applied.

이와같이 타이어 표면에 프라이머를 도포하고 전사지의 접착제층에 용제를 도포한 후, 이를 제3도에 도시된 바와 같이 전사지를 타이어(T)의 마킹부위에 올려넣고 로울러(10)로 2∼3회 가볍게 눌러 접착한후 이형지(1)를 떼어낸다.In this way, after applying a primer on the tire surface and a solvent on the adhesive layer of the transfer paper, put the transfer paper on the marking portion of the tire (T) as shown in Figure 3 and lightly 2 to 3 times with the roller (10) Press to bond, then remove the release paper (1).

이때 타이어(T)는 팽창된 상태일 것이 바람직하다.In this case, the tire T is preferably in an inflated state.

이와 같은 본 발명은 간단한 접착 작업만으로 마킹작업을 수행할 수 있어 종래의 백색고무 식입 돌출마킹 방법에 비한다면 커다란 생산성 증가 및 제조 원가 절감 효과를 얻을 수 있으며, 이질의 백색고무를매입시키지 아니하여 타이어의 균질성을 해하지 아니하므로 고성능을 요하는 경주용 자동차의 타이어에도 실시될 수 있는 효과가 있다.Such a present invention can perform the marking operation only with a simple adhesive operation can be obtained a large productivity increase and a reduction in manufacturing cost compared to the conventional white rubber etched extrusion marking method, the tire does not buy heterogeneous white rubber Since it does not harm the homogeneity of, there is an effect that can be carried out to the tire of a racing car that requires high performance.

또한 본 발명의 제조방법에 의해 제조된 타이어의 마킹표면은 UV보호막으로 처리되어 있어 종래와 같이 마킹표면 보호막을 설치할 필요가 없다. 뿐만 아니라 종래의 백색고무 식입 돌출마킹은 물리적 충격에 의해 파손되거나 노화에 의한 변색등에 발생하더라도 수리가 불가능하나, 본 발명의 제조방법에 의해 마킹을 실시한 타이어는 미리 제조된 전사지를 부착만하면 되므로 누구나 손쉽게 수리작업을 실시할 수 있는 효과가 있다.In addition, the marking surface of the tire produced by the manufacturing method of the present invention is treated with a UV protective film, and there is no need to provide a marking surface protective film as in the prior art. In addition, the conventional white rubber etch protruding marking is impossible to repair even if it is broken by physical impact or discoloration due to aging. However, the tire marked by the manufacturing method of the present invention can be easily attached to anyone since it is only required to attach a pre-fabricated transfer paper. It is effective to carry out repair work.
