“…Resol phenol -formaldehyde resins (RPFR) are widely used in the production technology of composite materials for various purposes [4,7,10,11,30]. These resins, along with the availability, cheapness and simplicity of the technology for preparing compositions, have a number of disadvantages [12,14,17,18,24].…”

The article presents the results of research on the production of effective inorganic fillers and chemically resistant composite polymer-mineral materials based on industrial waste. The aim of the work is to develop the technological foundations for the production of inorganic fillers and highly filled filling compositions for use in chlorine-containing media. Materials with high resistance to hydrochloric acid are graphite and quartz sand. Thermal power plant (TPP) ash was used as an acid-resistant filler in the compositions. The simplex lattice planning method was used to determine the areas of compositions with the best properties. Two components were selected: formaldehyde rubber resin and mineral filler (TPP ash) as a binder. As the third component, hydrolytically active fillers were used - anhydrite, phosphogypsum and phosphorus production slag. A preliminary operation was performed to remove hygroscopic moisture from the filler.The influence of the nature of mineral fillers on the chemical stability and durability of the obtained composites is investigated. The nature of the interaction of mineral fillers with a polymer binder was determined, and chemical interaction of the hydroxyl groups of the filler and the methyl groups of the polymer took place. The mathematical planning method was used to optimize the chemical resistance and durability of the compositions of the studied substances. Based on the results of this study, optimal compositions of compositions, anhydrite, phosphogypsum and phosphoric slag were selected. These composites, with the highest possible degree of filling, have high target characteristics.

“…In thermoset polymers, phenol-formaldehyde (PF) resin is one of the most common formaldehyde-based resins, which provides outstanding adhesion performance, high-temperature resistance, flame resistance, and electric insulation. Thus, phenol-formaldehyde (PF) resins have been and are still being used extensively in the industry [ 16 , 17 ]. Besides, the PF resin is a widely used wood adhesive in the industrial production of exterior-grade plywood panels, oriented strand board panels, and particleboards due to its excellent strength, temperature stability and resistance to moisture [ 18 ].…”

The effect of incorporating different loadings of oil palm bio-ash nanoparticles from agriculture waste on the properties of phenol-formaldehyde resin was investigated in this study. The bio-ash filler was used to enhance the performance of phenol-formaldehyde nanocomposites. Phenol-formaldehyde resin filled with oil palm bio-ash nanoparticles was prepared via the in-situ polymerization process to produce nanocomposites. The transmission electron microscope and particle size analyzer result revealed that oil palm bio-ash nanoparticles had a spherical geometry of 90 nm. Furthermore, X-ray diffraction results confirmed the formation of crystalline structure in oil palm bio-ash nanoparticles and phenol-formaldehyde nanocomposites. The thermogravimetric analysis indicated that the presence of oil palm bio-ash nanoparticles enhanced the thermal stability of the nanocomposites. The presence of oil palm bio-ash nanoparticles with 1% loading in phenol-formaldehyde resin enhanced the internal bonding strength of plywood composites. The scanning electron microscope image revealed that phenol-formaldehyde nanocomposites morphology had better uniform distribution and dispersion with 1% oil palm bio-ash nanoparticle loading than other phenol-formaldehyde nanocomposites produced. The nanocomposite has potential use in the development of particle and panel board for industrial applications.
