Tributyl Phosphate (TBP) is classified as organophosphorus compounds and shows a fire retardant effect in different material. In this work, lime splitting cattle leathers was tanned two type vegetable tannings, Mimosa (Group 1) and Tara (Group 2) and then TBP was applied to the non-finished vegetable tanned leathers at different concentrations. (0%, 7%, 14%, 21%) After the flame retardant mixture applied to the vegetable tanned leathers, samples were finished with a standard finishing recipe. Fire retardant effect on TBP treated leathers was determined by LOI test. Also morphological properties of leathers by SEM, molecular binding characterization of leathers by ATR-FTIR Analysis and color properties of leathers by CIE Lab Color Analysis were researched. The results showed that TBP treated vegetable tanned leathers were good flame retardant effect.

BİTKİSEL TABAKLANMIŞ DERİLERDE TRİ BÜTİL FOSFATIN (TBP) ALEV GECİKTİRİCİ ETKİSİ

Öz

Organo fosforlu bileşikler sınıfında yer alan Tribütil Fosfat kimyasalı; farklı materyallerde alev geciktirici etki göstermektedir. Bu çalışmada; kireçlik yarması sığır deriler Mimoza (Grup 1) ve Tara (Grup 2) olmak üzere iki çeşit bitkisel tabaklayıcı ile tabaklanmıştır ve sonrasında (0%,7%, 14%, 21%) farklı konsantrasyonlarda finisajı yapılmamış bitkisel tabaklanmış derilere TBP uygulanmıştır. Bitkisel tabaklanmış derilere alev geciktirici karışım uygulandıktan sonra örnekler standart bir finisaj reçetesi ile mamul hale getirilmiştir. TBP ile iyileştirilmiş derilerin alev geciktirici etkisi LOI testi ile tanımlanmıştır. Ayrıca SEM ile derilerin morfolojik özellikleri, ATR-FTIR ile derilerin moleküler bağ karekterizasyonu ve CIE Lab Renk Analizi ile derilerin renk özellikleri araştırılmıştır. Sonuçlar TBP ile iyileştirilmiş bitkisel tabaklanmış derilerin iyi bir alev geciktirici etkiye sahip olduğunu göstermiştir.
