흑색도와 부착성이 개선된 타이어 수리용 페인트 조성물{PAINT COMPOSITION IMPROVED BLACKNESS AND ADHESIVE FOR TIRE REPAIR}Tire repair paint composition with improved blackness and adhesion {PAINT COMPOSITION IMPROVED BLACKNESS AND ADHESIVE FOR TIRE REPAIR}

본 발명은 흑색도와 부착성이 개선된 타이어 수리용 페인트 조성물에 관한 것으로, 더욱 상세하게는 타이어와 도포물의 색차가 적어 수리 흔적이 드러나지 않으며, 부착성이 우수하여 타이어에 가해지는 마찰이나 충격에 도막이 씻기거나 벗겨지지 않는 타이어 수리용 페인트 조성물에 관한 것이다.The present invention relates to a paint composition for repairing tires with improved blackness and adhesion, and more particularly, a trace of repair due to a small color difference between the tire and the coating is not revealed, and the coating film is excellent in adhesion and friction applied to the tire. A paint composition for repairing tires that is not washed or peeled off.

타이어 제조시 가류공정 중 고무의 흐름 불량, 가류 후 몰드에서 탈착시 타이어 표면의 찢김 현상, 약품분산 문제 및 이물질 등에 의한 불량과 같이 공정상에 결함이 발생하며, 이와 같은 타이어의 외관에 대한 결함은 타이어 성능에는 영향을 주지 않으나 미관상의 문제로 인해 불량 처리되어 불량률 상승원인이 된다. When manufacturing tires, defects occur in the process such as poor flow of rubber during the vulcanization process, tearing of the surface of the tire when detaching from the mold after vulcanization, defects due to chemical dispersion, and foreign matters. It does not affect the tire performance, but due to aesthetic problems, it is treated poorly and causes a failure rate increase.

따라서, 이러한 타이어의 결함부위는 수리공정을 통해 수리하고, 수리한 흔적을 감추기 위하여 타이어 수리용 페인트를 도포한다.Therefore, the defective part of the tire is repaired through the repair process, and the tire repair paint is applied to hide the repaired trace.

상기한 타이어 수리용 페인트는 수리한 흔적을 감추기 위하여 타이어의 색상과 색차가 없거나 적어야하며, 수리공정을 단순하게 하기 위하여 별도의 건조과정 없이 자연상태에서 건조 및 경화가 이루어져야 한다. 또한 타이어의 장기간 보관시 에도 기온이나 습도 등과 같은 자연조건에 도막이 벗겨지거나 색상의 변화가 없어야 할 뿐만 아니라 운송이나 주행시에 발생하는 충격 또는 세차시에 도막에 손상이 없어야 한다.The above-mentioned tire repair paint should have no or little difference in color and color of the tire to hide the repaired trace, and should be dried and cured in a natural state without a separate drying process in order to simplify the repair process. In addition, long-term storage of the tire should not have peeling or color change due to natural conditions such as temperature and humidity, but also damage to the film during impact or car wash.

기존의 타이어 수리용 페인트는 유기 용제에 카본블랙과 합성고무를 용해, 분산시켜 사용하였으며, 근래에 들어 유기용제의 인체유해성 및 화재의 위험으로 폴리에스테르수지와 실리케이트 및 카본블랙 등을 물을 용매로 하여 분산시켜 사용하였다.Conventional tire repair paints have been used by dissolving and dispersing carbon black and synthetic rubber in organic solvents.In recent years, water has been used as a solvent for polyester resins, silicates, and carbon black due to the risk of human health and fire hazard. It was used by dispersing.

그러나 기존의 수리용 페인트는 착색제로 고무배합용 카본(Rubber black)을 사용하고 있어 타이어의 표면에 도포할 경우 도포부위의 색상이 타이어의 원색과 차이가 남에 따라 제품의 외관에 불만족스러운 경우가 많았다.However, the existing repair paint uses rubber black as a colorant, and when it is applied to the surface of the tire, there is a case that the appearance of the product is unsatisfactory because the color of the applied part is different from the primary color of the tire. Many.

상기 고무배합용 카본은 고무배합시 충전제의 목적으로 사용되는 것으로 배합시 인장강도 및 보강성등을 개선할 목적으로 사용하고. 주로 N200, N300, N400등이 사용되는데 사용의 편의를 위하여 카본입자는 왁스나 오일로 코팅된 그래눌(granular)타입을 사용한다.The rubber compounding carbon is used for the purpose of fillers in rubber compounding and is used for the purpose of improving tensile strength and reinforcement. Mainly N200, N300, N400, etc. are used. For the convenience of use, carbon particles use a granular type coated with wax or oil.

이러한 카본들은 단지 기계적 특성을 고려하여 제조된 것들로서, 잉크 및 도료에 사용하는 목적이 아니므로 미적인 측면이나 도장을 위한 특성이 배제되어 있으며, 단독으로 페인트의 안료로 사용하는 경우에는 피도체의 표면에서 광택이나 흑색도(Blackness)의 차이로 인해 타이어의 표면과 이질감을 주게 되는 단점이 있었다.These carbons are manufactured by considering mechanical properties only, and are not intended for use in inks and paints, and thus exclude aesthetic or paint properties, and when used alone as pigments in paint, the surface of the object Due to the difference in glossiness or blackness (Blackness) had a disadvantage of giving the tire surface and heterogeneity.

또한, 기존의 수리용 페인트로 도포된 타이어는 보관이나 운반시 대기중의 습기나 타이어 간의 접촉으로 인해 표면의 마찰 및 세차로 도막이 탈착되는 경우가 있었다. In addition, in the case of tires coated with conventional repair paints, the coating film may be detached due to friction on the surface and washing due to moisture in the air or contact between the tires during storage or transportation.

본 발명은 상기한 문제점을 해결하기 위하여 창안된 것으로, 본 발명의 목적은 착색력 및 흑색도가 우수한 안료용 카본을 사용하여 수리용 페인트의 도포 표면이 타이어 본래의 고무 색상과 이질감이 없도록 함으로써 수리흔적이 드러나지 않도록 하고, 소광제를 첨가하여 광택을 줄이고 잉크나 페인트가 같은 고유의 은은하고 미려한 색상을 지니도록 한 흑색도와 부착성이 개선된 타이어 수리용 페인트 조성물을 제공하는 데 있다.The present invention was devised to solve the above problems, and an object of the present invention is to use a pigment carbon having excellent coloring power and blackness, so that the coating surface of the repair paint does not have a difference between the tire's original rubber color and a sense of heterogeneity. The present invention provides a tire repair paint composition having improved blackness and adhesion, which is not exposed, and a matting agent is added to reduce gloss and make the ink or paint have the same unique silvery and beautiful color.

또한, 도막의 첨착성 및 견고성 등의 향상으로 타이어 표면에 대한 부착력을 높여 마찰이나 충격에 도막이 씻기거나 벗겨지지 않도록 한 흑색도와 부착성이 개선된 타이어 수리용 페인트 조성물을 제공함에 있다.In addition, the present invention provides a paint composition for repairing tires having improved blackness and adhesiveness by increasing adhesion to a tire surface by improving adhesion and firmness of the coating film so that the coating film is not washed or peeled off due to friction or impact.

Figure 112007092227935-pat00001
Figure 112007092227935-pat00001

상기 표 1에서와 같이 각각의 수리용 페인트를 제조하였으며, 비교예에서 실리케이트와 카본의 분산을 위해 별도의 분산작업 후 제조된 분산액을 나머지 성분과 혼합시켰다. 또한 실시예1과 실시예2의 경우에도 카본의 분산은 별도의 분산작업을 거친 후 분산액을 나머지 성분들과 고르게 혼합시켜 주었다.Each repair paint was prepared as shown in Table 1, and in the comparative example, a dispersion prepared after a separate dispersion operation for dispersing silicate and carbon was mixed with the remaining components. In addition, in the case of Example 1 and Example 2, the dispersion of carbon after the separate dispersion operation was evenly mixed with the remaining components.

아래의 표 2는 상기의 비교예와 실시예에 의하여 제조된 수리용 페인트를 사용하여 실제 타이어의 사이드 부분에 도포하여 작업성, 부착성, 내수성, 색상 및 건조성을 비교한 것이다.Table 2 below compares the workability, adhesion, water resistance, color and dryness by applying to the side of the actual tire using the repair paint prepared by the comparative examples and examples.

상기 작업성은 실제 타이어 공장에서 사용하는 방식으로 핸드 스프레이를 사용하여 도막의 균일성 및 흘러내림 등을 관찰하였고, 상기 부착성은 페인트가 건조된 후에 같은 힘으로 손으로 문질러 묻어나는 정도를 비교하였으며, 상기 내수성은 도막의 건조 후 타이어를 물에 침적시키고 표면에 물을 흘려보내서 도막이 씻기는지의 여부로 시험하였다.The workability was observed in the uniformity and dripping of the coating film using a hand spray in the manner used in the actual tire factory, and the adhesion property was compared with the degree of rubbing by hand with the same force after the paint was dried. The water resistance was tested by drying the coating film after immersing the tire in water and flushing the surface with water.

또한, 상기 색상은 육안으로 타이어의 표면상에서 페인트의 미도포 부위와 도포부위의 색차를 비교하였고, 상기 건조성은 각 제품을 상온에서 어플리케이터를 이용하여 30마이크로 미터의 도막으로 만든 후에 손으로 접촉시 손에 완전히 묻어나오지 않을 때까지의 시간을 측정하였다.In addition, the color was visually compared the color difference between the uncoated area of the paint and the coated area on the surface of the tire, the dryness of each product by using an applicator at room temperature using a coating film of 30 micrometers and then touched by hand The time until not completely buried in was measured.

Figure 112007092227935-pat00002

상기 표 2에서와 같이, 상기 표 1의 비교예의 스프레이에 의한 작업성은 양호한 수준이었으며, 부착성 시험시 손에 약간은 묻어나오는 경향이 있었으나 사용에 지장을 초래할 정도는 아니었으며, 도장표면의 색상은 페인트 특유의 광택으로 도포부위와 미도포 부위의 차이가 확연하였다.As shown in Table 2, the workability by the spray of the comparative example of Table 1 was a good level, and tended to be slightly stained on the hand during the adhesion test, but was not enough to cause problems in use, the color of the painted surface The distinctive gloss of the paint showed a clear difference between the coated and uncoated areas.

반면, 실시예1과 실시예2는 스프레이 작업성은 비교예와 같이 양호한 수준이었으며, 부착성은 거의 손에 묻어나오지 않을 정도로 우수하였다. 특히 타이어 도포시 비교예와 대비하여 훨씬 미려한 표면을 보여주었다. 그리고 흑색도면에서 우수하였고, 광택이 없어 도포면과 비도포면의 차이가 매우 적었다.On the other hand, in Example 1 and Example 2, the spray workability was a good level as in the comparative example, and the adhesion was excellent enough to hardly get on the hand. Particularly, when the tire was applied, the surface was much more beautiful than the comparative example. In addition, it was excellent in black drawing, and there was little difference between coated and uncoated surfaces because of lack of gloss.

이와 같이, 본 발명은 안료용 카본과, 콜로이달 실리카 분산액과, 우레탄수지 또는 에틸렌 비닐 아세테이트 수지를 사용하여 수리용 페인트의 부착성과 강도 및 내구성 등을 높이고, 소광제의 사용으로 미려한 외관을 갖도록 하여 기존의 수리용 페인트에 비해 보다 개선된 효과를 갖는 유용한 발명이다.As described above, the present invention uses pigment carbon, colloidal silica dispersion, urethane resin or ethylene vinyl acetate resin to increase the adhesion, strength and durability of the repair paint, and to have a beautiful appearance by using a matting agent. It is a useful invention with an improved effect compared to existing repair paints.
