Abstract
Bu çalışmada amaç, laminat parkenin yanmaya karşı dayanımını artırmaktır. Bu
nedenle, laminat parkenin taşıyıcı panelini oluşturan yüksek yoğunlukta lif levhalar (HDF)
için lif kaynağı olarak %50 kayın ve %50 sarıçam kullanılmıştır. HDF levhalar yangın
geciktirici (fire retardant) kimyasal maddeler ile muamele edilerek 6.5 mm kalınlıkta
üretilmiştir. Tam kuru lif miktarına oranla %3, %6, %9 oranlarında yanmayı geciktirici
boraks, borik asit, amonyum polifosfat ve alfa-x kimyasalları toz halinde ilave edilmiştir.
Daha sonra, HDF levhalarının yüzeyleri overlay, dekor ve balans kağıtları ile kaplanmış ve
laminat parkeler üretilmiştir. Elde edilen laminat parke deneme levhalarında standartlara
bağlı kalınarak fiziksel, mekanik, yüzey kalitesi özellikleri, serbest formaldehit miktarı,
mantar çürüklük dayanımı ve yanma özellikleri araştırılmıştır. %3, %6 ve %9 oranlarında
yanmayı geciktirici olarak ilave edilen kimyasalların, levhaların yanma dayanımını, mantar
çürüklüğü ve küf mantarı dayanımını artırdığı fakat fiziksel ve mekanik direnç özelliklerini
olumsuz etkilediği belirlenmiştir. Yanmayı geciktirici kimyasal maddelerin HDF levhalara
ilave edilmesi ile laminat parkenin yüzey kalitesi özellikleri üzerine etkilerinin olmadığı
ancak melamin emdirilmiş kağıtlara uygulanmasında ise olumsuz etki yaptığı tespit
edilmiştir.
The aim of this study to improve the fire resistance of laminate flooring. Therefore, high density fiber boards contain mixture of 50% of Beech and 50% of Scots Pine were used for laminated flooring boards. High density fiber boards were produced using flame retardant chemicals with the thickness of 6.5 mm. Fire retardants such as borax, boric acid, ammonium polyphosphate and alpha-x-chemicals were added in the powder form with the concentration of 3%, 6% and 9% of dry fiber weight. Afterwards, surfaces of HDF boards were coated with overlay, decor and balance sheets and then laminated floorings boards were produced. The physical, mechanical, surface properties, amounts of free formaldehyde, resistance of fungal decay and fire resistance of all produced laminated flooring samples were investigated in accordance to relevant standarts. Addition of fire retardant chemicals such as borax, boric acid, ammoniumpolyfosfat and alfa-x,were at 3%, 6% and 9% proportions improved the fire resistance, fungal decay and mold resistance but had a negative effect on both the physical and mechanical properties. It was also detectedthat the internal addition of fire retardant chemicals had no negative effects on the surface quality of HDF boards whereas the application of such chemicals on the melamineimpregnated papers had destructive effects on the surface properties of tested samples
