چکیده
Sustainable coating solutions that function as a fire retardant for wood are still challenging topic the academic and industrial sectors. In this study, composite coatings of casein protein mixed with mica aluminum trihydroxide (ATH) were tested retardants plywood; degradation retardancy performance assessed cone calorimeter, thermogravimeter was used thermal stability measurement. The results indicated casein–mica composites beneficial coatings. heat release rate (HRR) total released (THR) sample coated reduced by 55% 37%, respectively; time to ignition increased 27% compared untreated sample. However, TTI casein–mica–ATH 156%; PHR THR 31% 28%, respectively. This is attributed yielded insulating surface layer, active catalytic sites, crosslink from endothermic decomposition ATH producing different fragments which create multiple modes action, leading significant roles in suppressing spread. action involved prepared presented detail. Coating wear resistance investigated using Taber Abrader, adhesion interaction between applying pull-off test. While addition three filler types caused decrease strength up 38%, their abrasion greatly much 80%.

The optimum level of nano-wollastonite consumption as fire-retardant in poplar wood (Populus nigra)
Fire-retarding properties of wollastonite nanofibers in poplar wood (Populus nigra) were studied here. Some physical properties such as water absorption, volumetric swelling and anti-swelling efficiency (ASE) were also measured. Specimens were prepared according to the ISO 11925 specifications for the fire-retarding properties and according to the ASTM D4446 -2002 specifications for th...

متن کاملUtilization of Magnesium Hydroxide Produced by Magnesia Hydration as Fire Retardant for Nylon 6-6,6
The present work investigates the use of magnesium hydroxide, produced by magnesia hydration, as a fire retardant in polymers. The hydration was carried out in an autoclave, at temperature of 130°C for 1 hour, and the product was further submitted to cominution in a jet mill. The solids were characterized with regard to their chemical composition, particle size distribution, surface area and mo...
