Description

스노우 타이어용 트레드 고무 조성물{Tread rubber compound for a snow tire}Tread rubber compound for a snow tire

본 발명은 스노우용 고무조성물에 환경규제를 받고 있는 PCA(Polycyclic aromatics)함량을 3% 미만으로 낮춘 오일과 중금속인 카드뮴과 납함량을 0.006%, 0.1% 미만으로 낮춘 아연화를 사용하여 기존의 아로마틱 오일과 아연화를 사용했을 때와 동일한 제반물성을 갖는 유해 물질을 최소화한 환경 친화적인 트레드 고무 조성물에 관한 것이다.The present invention is a conventional aromatic oil by using a zinc-lower oil lowering the content of cadmium and lead, which is a heavy metal lowered to less than 3% and PCA (Polycyclic aromatics) content under environmental regulations in the rubber composition for snow to less than 0.16%, 0.1% The present invention relates to an environment-friendly tread rubber composition which minimizes harmful substances having the same general properties as when using super-zincification.

종래에는 고무조성물에 보강제를 첨가하면 경화되기 때문에 배합고무의 유연성, 가공성을 개선할 목적으로 고무 분자간의 윤활제로 작용시켜 고무주고의 친화현상을 촉진하는 연화제인 오일을 사용하였다.Conventionally, since a hardening agent is added to a rubber composition, it is cured, and thus, an oil, which is a softening agent that acts as a lubricant between rubber molecules and promotes affinity of rubber, is used for the purpose of improving the flexibility and processability of compounded rubber.

특히 아로마틱 오일은 오염성, 저온특성, 발열 등은 타 오일보다 나쁘지만 가공성이 우수하여 주로 사용되어 왔으나, 최근 PCA를 함유한 오일을 이용하여 동물실험을 실시한 결과 PCA함량이 3% 이상일 경우 피부암을 유발할 가능성이 있는 것으로 보고되어, 유럽에서 오일내 PCA함량을 3%미만으로 규제하고 있다.In particular, aromatic oils have been used mainly due to their poor pollutability, low temperature characteristics, heat generation, etc., but they are excellent in processability.However, recently, animal experiments using PCA-containing oils may cause skin cancer when PCA content is 3% or more. It is reported that there is a restriction on PCA content in oil of less than 3% in Europe.

활성제로 널리 사용되는 아연화는 스테아린산과 반응하여 징크-스테아레이트를 형성하여 촉진제를 활성화시키는 역할을 하기 때문에 가류반응에 반드시 첨가되어야 하는 재료 중의 하나로 통상 3~10phr을 첨가하고 있다.Zincation, which is widely used as an activator, reacts with stearic acid to form zinc-stearate and thus activates an accelerator, and therefore, 3 to 10 phr is usually added as one of materials that must be added to the vulcanization reaction.

최근 유럽의 폐차 리사이클에 대한 법규 중 폐기물 및 유해물질(납, 카드뮴, 수은, 6가 크롬 등) 규제에 관련하여 타이어 내 중금속 함량을 낮추는 추세이다.Recent legislation on recycling waste trucks in Europe has led to a trend to lower the amount of heavy metals in tires related to waste and hazardous substances (lead, cadmium, mercury, hexavalent chromium).

이에 환경 규제치에 맞는 오일 및 아연화를 적용한 환경친화적인 고무 조성물의 개발이 요구되어 진다.Therefore, development of an environmentally friendly rubber composition applying oil and zinc that meets environmental regulations is required.

상기의 문제점을 해결하기 위하여 안출된 본 발명의 목적은, PCA함량이 낮은 오일과 중금속 함량이 낮은 아연을 고무조성물에 첨가함으로써, 기존의 스노우용 고무 조성물과 동일 물성을 가지며, 유해물질을 최소화한 환경 친화적인 고무조성물을 제공함에 있다.An object of the present invention devised to solve the above problems is, by adding zinc with a low PCA content oil and low metal content to the rubber composition, has the same physical properties as the rubber composition for snow, and minimizes harmful substances To provide an environmentally friendly rubber composition.

본 발명은 스노우 타이어용 고무 조성물에 대한 PCA함량이 낮은 오일과 중금속 함량이 낮은 아연을 적용한 환경 친화적인 고무조성물에 관한 것으로, 디엔계 고무에 LOW PCA오일을 10~40phr첨가함으로써, 기존의 스노우용 고무 조성물과 동일 물성을 가지며, 유해물질을 최소화한 환경 친화적인 고무조성물에 관한 것이다.The present invention relates to an environmentally friendly rubber composition using a low PCA content of oil and a low metal content zinc for a rubber composition for snow tires, by adding 10-40 phr of LOW PCA oil to the diene rubber, The present invention relates to an environmentally friendly rubber composition having the same physical properties as the rubber composition and minimizing harmful substances.

주원료가 되는 고무조성물은 SBR과 BR과 천연고무로 구성되거나, BR 또는 천연고무로 구성된다.The main rubber composition consists of SBR and BR and natural rubber, or BR or natural rubber.

상기에서 전자의 조성은 SBR 50~60중량부, BR 15~25중량부, 천연고무 35~45중량부가 바람직하며, 후자의 조성은 BR 35~45중량부, 천연고무 55~65중량부가 바람직하다.The composition of the former is preferably SBR 50-60 parts by weight, BR 15-25 parts by weight, natural rubber 35-45 parts by weight, the latter composition is BR 35-45 parts by weight, natural rubber 55-65 parts by weight. .

상기에서 오일의 PCA함량은 바람직하게는 3% 이하이며, 상기에서 아연화의 카드뮴 함량은 0.006%이하이고 납 함량이 0.1%이하로 하는 것이 바람직하다.In the above, the PCA content of the oil is preferably 3% or less, wherein the cadmium content of zincation is preferably 0.006% or less and the lead content is 0.1% or less.

상기에서 PCA의 함량이 적은 오일의 사용량은 10~40phr으로 하며, 저카드뮴 저납인 아연화의 사용량은 3~10phr인 것이 바람직하다.In the above, the amount of oil having a low content of PCA is 10 to 40 phr, and the amount of low cadmium low lead zincation is preferably 3 to 10 phr.
