Abstract

Natural rubber-based composite mixtures (NRC) are widely used as commercial material in vehicle tires, shock absorbers, suspension system components, and various engineering applications due to their superior performance properties. In addition to the extremely severe conditions of the working environments of rubber-based materials, it also contains a serious fire safety problem. In this study, thermal, flame retardant and mechanical properties of rubber composite mixtures prepared with the addition of carbon black (CB) and intumescent flame retardant agents (IFR) with different particle sizes to be used as raw materials in air suspension systems were investigated. The effect of filler materials and flame retardants used on NRC was investigated using thermal analysis (TGA), combustion tests, mechanical tests, SEM, and microscopic studies. It was observed that the thermal stability and flammability of the composites depend on the network structure, the content, and the type of the additive in the mixture obtained. Particle size reduction has a significant role on reducing NRCs flammability while also increasing their mechanical properties.

Özet

Doğal kauçuk esaslı kompozit karışımları (NRC), sahip oldukları üstün performans özellikleri sebebiyle araç lastiklerinde, amortisörlerde, süspansiyon sistem elemanları ve çeşitli mühendislik uygulamalarında bir tür ticari malzeme olarak yaygın bir şekilde kullanılmaktadır. Kauçuk esaslı malzemeler çalıştığı ortamlarda son derece ağır şartlara maruz kalmasının yanında ciddi bir yangın güvenliği sorununu da bünyesinde barındırmaktadır. Bu çalışmada, havalı süspansiyon sistemlerinde hammadde olarak kullanılacak farklı partikül boyutlarına sahip karbon siyahı (CB) ve alev ısısı ile reaksiyona girerek kabaran alev geciktirici ajanların (SRA) ilavesi ile hazırlanan kauçuk kompozit karışımlarının termal, alev geciktirici ve mekanik özellikleri araştırılmıştır. Kullanılan dolgu malzemeleri ve alev geciktiricilerin NRC üzerindeki etkisi termal analizler (TGA), yanma testleri, mekanik testler, SEM ve mikroskobik analizler ile incelenmiştir. Kompozitlerin ısıl kararlılığı ve yanıcılığı ağ yapısına, elde edilen karışımdaki katkı maddesinin içeriğine ve tipine bağlı olduğu gözlemlenmiştir. Parçacık boyutunun küçültülmesi, NRC'lerin yanıcılığını azaltırken aynı zamanda mekanik özelliklerini de arttırmada önemli bir role sahiptir.
