“…Various traditional thermoplastics such as polythene, polypropylene, acrylonitrilebutadiene-styrene copolymers, polyamide, polystyrene, poly(methyl methacrylate), poly(vinyl acetate), and polycarbonate were used as matrixes of polymer-wood composites [3][4][5][6][7][8][9][10]. These materials were also manufactured using thermosetting plastics like epoxy, polyurethane, and phenolic resin [11][12][13][14][15][16].…”

This paper presents the results of a study of the properties of a new composite material made from poly(vinyl chloride) plastisol (PVC) and conifer-derived wood flour. The material can be used for thermal insulation, floor coverings with high resistance to mechanical trauma, and protective coatings. The plastisol was made from emulsion poly(vinyl chloride), the plasticiser was bis(2-ethylhexyl) adipate, and the stabiliser was octyltin mercapeptide. Two types of flour were used: fine-grained and coarse-grained. Its properties, such as bulk density, oil number, and plasticiser number, were determined. The polymer-wood composite contained 20 or 30 wt.% wood flour in PVC. Plastisol was obtained by repeated mixing, mashing, and venting under vacuum. The produced composite material was gelated at temperatures of 130, 150, and 170 °C. The gelation process of the composites was studied in a Brabender apparatus. Samples in the form of polymer films were used to study density, hardness, thermal stability, and mechanical and thermomechanical properties. The structure of the composites was observed by scanning electron microscopy (SEM). A summary of all test results showed that composite films made from PVC plastisol with 20 wt.% of fine wood flour gelled at 150 °C had the most favourable physical, mechanical, and thermal properties.

“…These materials were also manufactured using thermosetting plastics like epoxy, polyurethane, and phenolic resin [11][12][13][14][15][16]. Fibre, wood chips, sawdust, and wood flour were used as fillers [3,4,8,9,11]. The wood material came from both deciduous and coniferous trees [6,[15][16][17].…”

“…However, these resins still have the main drawback of formaldehyde emission. According to the World Health Organization (WHO), formaldehyde is categorized as a carcinogen that causes environmental and health problems, and consequently the manufacturing of environmentally friendly adhesives to replace aldehyde-based adhesives has raised significant attention 2 . Biopolymer-based adhesives are promising non-toxic, inexpensive, and renewable alternatives 3 , 4 .…”

Environmentally friendly biopolymer-based wood adhesives are an inevitable trend of wood product development to replace the use of harmful formaldehyde-based adhesives. In this research, a new eco-friendly modified cassava starch waste-based adhesive via carboxymethylation (CMS), and blending with polyvinyl alcohol (PVA), tannic acid (TA) and green synthesized silver nanoparticles (AgNPs) was prepared. The effects of TA content on green synthesis of AgNPs (Ag-TA) and bio-adhesive nanocomposite properties were investigated. The use of 5 wt% TA for AgNPs synthesis (Ag-TA-5) resulted in a uniform particle size distribution. The plywood prepared with Ag-TA-5 provided the highest dry and wet shear strength at 1.95 ± 0.11 MPa and 1.38 ± 0.3 MPa, respectively. The water absorption and thickness swelling of this plywood remarkably decreased up to 10.99% and 6.79%, respectively. More importantly, the presence of Ag-TA in CMS/PVA adhesive successfully inhibited the invasion of mold and bacteria. Based on the cyclic delamination test, the adhesive bond durability of bio-adhesive containing Ag-TA-5 could meet the requirement of the AITC Test T110-2007 and was comparable to commercial adhesives. The added advantage of the prepared bio-adhesive was its synthesis from agro-waste products and possible economically viable production at industrial level.

“…In recent years, natural fibers, such as cotton, hemp, bamboo, and wood, have gained attention as suitable materials for reinforcing the polymer resin [11][12][13][14][15]. It has been reported that the incorporation of these materials improves the mechanical properties of WPCs by controlling their contents and interfacial properties [13,16,17].…”

“…However, the free energy of WPCs and wood veneer is low [24], and so it is necessary to improve the compatibility and interactions between these two materials to provide a suitable composite [25]. For this purpose, films such as MAPE and MAPP, as mentioned above, are often used to substitute traditional adhesives to improve the interfacial bonding properties and produce environmentally friendly composites [7,10,11,26]. In addition to the above methods, silane coupling agents, such as KH550, can impart wood veneers with a surface polarity, effectively enhancing the interfacial bonding strength and water resistance simultaneously [10,23,27].…”

Wood–plastic composites (WPCs) have received growing attention due to their good water resistance, environmental friendliness, and recyclability. For the application of WPCs in interior decoration and other high–value fields, it is necessary to preserve these characteristics whilst enhancing their mechanical properties and surface aesthetics. In this study, we used a sandwich structure and four interface modifiers to prepare wood veneer/wood flour–polyvinyl chloride composites (WWPVCs). The results revealed that the WWPVCs treated with a silane coupling agent exhibited superior interfacial bonding and mechanical properties compared to those obtained using other interface modifiers. The interfacial bonding strength of the treated sample reached 1.22 MPa, which was 122% higher than that of the untreated sample. In addition, the wood failure ratio of the optimal sample reached 80%. Furthermore, the dipping–peeling length was found to be shorter than those achieved using other interface modifiers after tests at 63 and 100 °C, indicating that the material treated using the silane coupling agent exhibits an excellent resistance to moisture and heat. Notably, silane coupling agents are easily prepared as solvent–based modifiers, and they do not release harmful gases (e.g., formaldehyde), thereby rendering them highly effective in the preparation of environmentally friendly WPC products.
