Abstract The demand for particleboard is increasing along with economic and population growth. However, two major barriers to the manufacture of particleboard are a shortage of raw materials (woodchips) and the emission of formaldehyde from conventional adhesives. Agricultural by-products such as corn stalks contain an abundance of renewable lignocellulosic fiber. This study evaluates the effect of citric acid as a natural adhesive and fire retardant addition on the physical, mechanical, and fire retardancy properties of particleboards fabricated from corn stalks. A cost-effective and inorganic salt, calcium carbonate, was tested to enhance the fire retardancy. Ammonium dihydrogen… More > Graphic Abstract

Abstract Corn stalk cellulose (CS)/used rubber powder (RP) composites were prepared by mixing, the silane coupling agent 3-Mercaptopropyl trimethoxysilane (KH590), r-Aminopropyltrieth oxysilane (KH550), isopropyl dioleic (dioctylphosphate) titanate (HY101) and bis-(γ-triethoxysilylpropyl)- tetrasulfide (Si69) were used to modify the interface of composites. The effects of the CS and coupling agents on the mechanical properties, thermal properties, interfacial morphology and structure of the composites were investigated, respectively. The results showed that the addition of CS could effectively improve the mechanical properties of the composites. Compared with the untreated composites, the interfacial bonding between CS and RP was significantly improved More >
