Production of insulation material using styrene acrylic resin from animal and agricultural waste part 2: Mechanical properties, fire retardant, acoustic properties.

In this study, it was aimed to utilize the wastes of wheat straw, goose down and wood industry and bring them into the economy. A sustainable insulation material was produced using environmentally friendly water-based PVA styrene acrylic copolymer as a binder with these wastes. In the study, mechanical properties, acoustic absorption and burning resistance were examined. Response Surface Method Box-Behnken Design (RSM-BBD) was used for experimental design and optimization. As a result of mechanical tests, it was seen that the binder ratio had a very high effect on mechanical strength. It was observed that the acoustic absorption coefficient increases with the increase of each of wheat straw, wood shaving, goose down and water-based copolymer resin. Styrene acrylic copolymer was found to be suitable binder for agricultural wastes. AL 2 O 3 , MgO, and Zn[B 3 O 4 (OH) 3 ] were used to increase fire resistance. The results revealed that these compounds can be used as fire retardants for materials consisting of cellulosic-based fillers and water-based polymer binders. The best combustion results for the material were achieved with Zn[B3O4(OH)3]. Flame retardants reduced cellulosyl and polymeric mass loss by up to 61.5 %. It was observed that the best fire resistance was F27 sample, which started to extinguish after two minutes despite the continuation of the fire and extinguished immediately after the fire was removed. The study revealed that such materials can rival conventional materials for green credentials, technical, economic, and environmental aspects. • Styrene acrylic copolymer was found to be suitable binder for agricultural wastes. • Flame retardants reduced cellulosyl and polymeric mass loss by up to 61.5 %. • The best combustion results for the material were achieved with Zn[B 3 O 4 (OH) 3 ]. • Al 2 O 3 , MgO and Zn[B 3 O 4 (OH) 3 ] were suitable fire retardants for sample materials. • Wheat straw, sawdust, goose down and polymer had a good effect on sound insulation.
