Description

상용차의 공기스프링 타이어용 고무 조성물Rubber composition for pneumatic spring tires of commercial vehicles

본 발명은 상용차의 공기스프링 타이어용 고무 조성물에 관한 것으로, 더욱 상세하게는 가공 조제 및 오일을 사용하여 클로로프렌 고무의 함량을 증가시킴으로서 내열노화성 및 내오존성이 향상된 상용차의 공기스프링 타이어용 고무 조성물에 관한 것이다.The present invention relates to a rubber composition for a commercial vehicle air spring tire, and more particularly, to a rubber composition for a commercial vehicle air spring tire having improved heat aging resistance and ozone resistance by increasing the content of chloroprene rubber using processing aids and oils. It is about.

일반적으로상용차의 공기스프링 타이어용 고무 조성물에는 천연 고무 또는 천연 고무에 클로로프렌 고무를 소량 섞어서 사용하고 있다.In general, a small amount of chloroprene rubber is mixed with natural rubber or natural rubber in a rubber composition for commercial air spring tires.

상기한 종류의 고무 조성물은 신장율, 인장강도 및 내피로성 등은 우수하지만, 공기스프링 타이어 고무의 요구 특성인 내열노화성 및 내오존성이 불량하여 공기스프링 수명을 단축시킨다.The rubber composition of the above kind is excellent in elongation, tensile strength, fatigue resistance, etc., but shortens the air spring life due to poor heat aging resistance and ozone resistance, which are required characteristics of air spring tire rubber.

클로로프렌 고무는 내열노화성 및 내오존성이 우수하여 공기스프링의 요구 특성을 만족시키기 위하여 천연 고무와 함께 공기스프링 타이어용 고무 조성물에 첨가된다.Chloroprene rubber is added to the rubber composition for an air spring tire together with natural rubber in order to satisfy the required characteristics of the air spring because of excellent heat aging resistance and ozone resistance.

그러나, 천연 고무에 첨가할 수 있는 클로로프렌 고무는 최대 50중량부로 그 사용량이 제한되는데, 그 이상으로 사용하게 되면 가공시 점착 문제가 발생하여 반바리 혼합성 및 카렌다 작업성이 좋지 못하게 된다.However, the amount of chloroprene rubber that can be added to the natural rubber is limited to a maximum of 50 parts by weight, when used in excess of the adhesion problem occurs during processing, short-barrier mixing and calendar workability is not good.

본 발명자들은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 예의 연구한 결과, 상용차의 공기스프링 타이어용 고무 조성물에 가공조제 및 오일을 첨가하여 클로로프렌 고무를 다량 사용하게 되므로써 상용차의 공기스프링 타이어용 고무 조성물의 내열노화성 및 내오존성을 향상시킬 수 있음을 알게 되어 본 발명에 이르게 되었다.The present inventors earnestly studied in order to solve the problems of the prior art as described above, by adding a processing aid and oil to the rubber composition for the air spring tire of a commercial vehicle, a large amount of chloroprene rubber is used, so that the rubber for the air spring tire of a commercial vehicle It has been found that the present invention can improve the heat aging resistance and ozone resistance of the composition.

이에 본 발명은 방향족 오일, 나프텐 오일 또는 파라핀 오일 등의 오일과 가공조제로서 석유계 수지를 사용하여 상용차의 공기스프링 타이어용 고무 조성물에 클로로프렌 고무를 다량, 바람직하게는 최대로 90 중량부까지 사용하여 상용차의 공기스프링 타이어의 내열노화성 및 내오존성을 향상시키는데 그 목적이 있는 것이다.Accordingly, the present invention uses a large amount, preferably up to 90 parts by weight of chloroprene rubber in the rubber composition for air spring tires of commercial vehicles using oils such as aromatic oils, naphthene oils or paraffin oils and petroleum-based resins as processing aids. The purpose is to improve the heat aging resistance and ozone resistance of the air spring tire of a commercial vehicle.

본 발명은 천연 고무 10 내지 30 중량부에 클로로프렌 고무를 70 내지 90 중량부를 혼합하여 전체 고무의 합을 100 중량부로 하고, 전체 고무 100 중량부당 질소 흡착 표면적이 30 내지 41㎡/g이며, DBP 흡유량이 85 내지 97㎤/100g인 카본 블랙 30 내지 70 중량부, 방향족계와 탄화수소계 수지의 혼합물 1 내지 5 중량부, 오일 5 내지 15 중량부, 가류 촉진제 0.2 내지 2 중량부, 유황 0.5 내지 3 중량부, 산화아연 2 내지 10 중량부 및 산화마그네슘 1 내지 8 중량부로 이루어지는 것을 특징으로 하는 상용차의 공기스프링 타이어용 고무 조성물인 것이다.In the present invention, 70 to 90 parts by weight of chloroprene rubber is mixed with 10 to 30 parts by weight of natural rubber to add 100 parts by weight of the total rubber, and the nitrogen adsorption surface area is 30 to 41 m 2 / g per 100 parts by weight of the total rubber, and the DBP oil absorption amount 30 to 70 parts by weight of carbon black having 85 to 97 cm 3/100 g, 1 to 5 parts by weight of a mixture of aromatic and hydrocarbon resins, 5 to 15 parts by weight of oil, 0.2 to 2 parts by weight of vulcanization accelerator, and 0.5 to 3 parts by weight of sulfur. It is a rubber composition for a pneumatic spring tire of a commercial vehicle, characterized by consisting of 2 to 10 parts by weight of zinc oxide and 1 to 8 parts by weight of magnesium oxide.

이하, 본 발명을 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에서는 상용차의 공기스프링 타이어용 고무 조성물에 있어서, 천연 고무 10 내지 30 중량부에 클로로프렌 고무를 70 내지 90 중량부를 혼합하여 전체 고무의 합을 100 중량부로 한다.In the present invention, in the rubber composition for an air spring tire of a commercial vehicle, 70 to 90 parts by weight of chloroprene rubber is mixed to 10 to 30 parts by weight of natural rubber to add 100 parts by weight of the total rubber.

천연 고무는 신장율, 인장강도 및 내피로성은 우수하지만, 내열노화성 및 내오존성은 저조하므로서, 이러한 단점을 클로로프렌 고무가 보완해준다.Although natural rubber has excellent elongation, tensile strength and fatigue resistance, chloroprene rubber compensates for these disadvantages due to low heat aging and ozone resistance.

클로로프렌은 트랜스-1,4 구조 또는 시스-1,4 구조를 갖는 폴리클로로프렌을 사용한다.Chloroprene uses polychloroprene having a trans-1,4 structure or a cis-1,4 structure.

카본 블랙은 보강제로 사용되며 전체 고무 100 중량부당 30 내지 70 중량부를 사용한다. 카본 블랙은 질소 흡착 표면적이 30 내지 41㎡/g인 것이 바란직한데, 이 범위 이이의 것을 사용하면 보강 효과가 충분하지 못하다. 또한, 카본 블랙의 DBP 흡유량은 85 내지 97㎤/100g인 것이 바람직한데, DBP 흡유량이 상기 범위를 벗어나는 카본 블랙은 고무내에서의 분산성이 떨어진다.Carbon black is used as a reinforcing agent and 30 to 70 parts by weight per 100 parts by weight of the total rubber. It is desirable that the carbon black has a nitrogen adsorption surface area of 30 to 41 m 2 / g, but a reinforcing effect is not sufficient when using a material in this range or more. In addition, the DBP oil absorption of the carbon black is preferably 85 to 97 cm 3/100 g, but the carbon black whose DBP oil absorption exceeds the above range is poor in dispersibility in rubber.

방향족계와 탄화수소계 수지의 혼합물은 전체 고무 100 중량부당 1 내지 5 중량부를, 오일은 5 내지 15 중량부를 첨가한다. 오일과 가공조제인 방향족계와 탄화수소계 수지의 혼합물은 클로로프렌 고무를 종래 가공상의 이유로 천연 고무에 대해 최대로 50 중량부까지 사용하던 것을 점착 문제를 해결하여 최대 90 중량부까지 사용할 수 있도록 해준다.The mixture of the aromatic and hydrocarbon resins is added 1 to 5 parts by weight per 100 parts by weight of the total rubber, and 5 to 15 parts by weight of oil. The mixture of oil and processing aids, aromatic and hydrocarbon resins, allows the use of up to 50 parts by weight of chloroprene rubber for up to 50 parts by weight of natural rubber for conventional processing reasons.

본 발명에서 사용할 수 있는 오일은 방향족 오일, 나프텐 오일 또는 파라핀 오일이다.Oils that can be used in the present invention are aromatic oils, naphthenic oils or paraffin oils.

가류 촉진제, 유황, 산화아연 및 산화마그네슘의 사용량에 있어서, 전체 고무 100 중량부당 가류 촉젠제 0.2 내지 2 중량부, 유황 0.5 내지 3 중량부, 산화아연 2 내지 10 중량부 및 산화마그네슘 1 내지 8 중량부를 사용하며, 이 사용 범위를 벗어나면 가류시간이 부적합하게 된다.In the amount of vulcanization accelerator, sulfur, zinc oxide and magnesium oxide, 0.2 to 2 parts by weight of vulcanization accelerator, 0.5 to 3 parts by weight of sulfur, 2 to 10 parts by weight of zinc oxide, and 1 to 8 parts by weight of magnesium oxide per 100 parts by weight of the total rubber. Wealth is used, and if it is out of this range, the vulcanization time becomes inadequate.

가류 촉진제로는 테트라메틸티우람 디설파이드, 테트라메틸티우람 모노설파이드, 에틸렌 티오우레아 또는 디에틸 티오우레아를 사용한다. 유황은 천연유황, 디알킬디설파이드, 디아릴설파이드, 알킬페놀디설파이드 또는 디티오디몰포린을 사용한다.Tetramethylthiuram disulfide, tetramethylthiuram monosulfide, ethylene thiourea or diethyl thiourea are used as vulcanization accelerators. Sulfur uses natural sulfur, dialkyl disulfides, diaryl sulfides, alkylphenol disulfides or dithiodimorpholin.

상기와 같은 본 발명의 방법에 의해 클로로프렌 고무를 다량 사용하고 천연 고무를 소량 사용한 고무 조성물은 천연 고무를 다량, 클로로프렌 고무를 소량 사용한 고무 조성물과 비교하여 내피로성을 유지하면서 내열노화성 및 내오존성이 크게 향상된다.The rubber composition using a large amount of chloroprene rubber and a small amount of natural rubber by the method of the present invention as described above, compared to the rubber composition using a large amount of natural rubber and a small amount of chloroprene rubber, while maintaining fatigue resistance and resistance to heat aging and ozone Greatly improved.
