It is anticipated that the creation of wood-polymer composites (WPC) made of naturally renewable polymers and their derivatives (biocomposites) would have a significant practical use due to the rise in prices for synthetic thermoplastic polymers derived from oil and gas. Furthermore, the necessity to replace synthetic polymers such as polyethylene, polypropylene, polyvinyl chloride, and others as components of composite materials is also associated with environmental hazards caused by their low degradation rate in the natural media (soil, water, and air). A further problem for manufacturers of WPC is the legislative requirement for autonomous neutralisation of production waste. One of the potential materials for practical application in the production of WPC are binders based on plasticised cellulose acetates. Russian and foreign scientists have studied the influence of the degree of acetylation of cellulose acetate on the properties of polymeric materials that do not contain lignocellulose fillers. There is no information found concerning the secondary use of cellulose acetate waste for the production of WPC. This article presents the results of an investigation into the hot pressing of biocomposites with a polymer phase of plasticised cellulose acetates of varying degrees of acetylation and fillers: wood flour and waste acetate photographic film. An experimental and statistical dependence of the effect of the degree of acetylation of cellulose acetate and filler content in the biocomposite on its properties was developed, sufficient to exceed a confidence level of 0.9. The experimental specifications included decomposition in activated soil, water absorption, bending strength, Brinell hardness, etc. Some test results showed that the derived biocomposites have the same level of properties as the reference WPC, which consists of a high-density polyethylene phase with a wood flour content of 50 %. The derived dependencies allow us to predict changes in the properties of biocomposites at different degrees of acetylation of plasticised cellulose acetate and filler content. Moreover, they solve the problem of choosing the optimal chemical combination for WPC for manufacturing a specific product by hot pressing. © 2023, Northern Arctic Federal University named after M V Lomonosov.
