“…In all the samples, the torque values were lower, compared to the silicone index without inclusions, except for the sample with 10% filler added from the total weight of the material. The composite FarEastCon -Materials and Construction material obtained with the addition of wood flour filler added Smin and Smax, since the presence of fillers imparts a constraint on the deformation of the composite, and therefore the composite becomes harder and harder [9][10][11][12]. An excess of wood flour in the composite can lead to a deterioration in the bond between the filler and the base material (silicone) -the adhesive strength, and thus lead to a deterioration in the mechanical properties of the resulting composite.…”

According to modern standards, all courtyard, school and public playgrounds on which gaming equipment is installed must undergo tests of shock absorption of the surface under and around the equipment to prevent serious injuries to the child. In this regard, widely spread coatings on the basis of rubber chips. However, they not only do not meet the aesthetic requirements, but can also worsen the environmental situation when operating indoors. The paper describes a method for producing composites from wood flour and a silicone binder. The effect of wood meal content on the water absorption of composites as well as the effect of silicone content on the density of the results of the research showed that an increase in the content of wood flour significantly increases the water absorption of the resulting composite, that the composite material obtained with the addition of filler from wood meal, the values of the maximum and minimum elastic moment increased, since the presence of fillers imparts a restriction on the deformation of the composite, and, consequently, the composite becomes harder and harder. As a result of the studies carried out, it can be concluded that the use of silicone as binder and shredded wood waste as a filler makes it possible to obtain good quality elastic flooring with high aesthetic, operational and environmental properties.

“…Traditional synthetic polymers and composites based on them, in particular, polyethylene, despite the successful combination of production technology, the possibility of varying physical and mechanical characteristics and prices, create significant problems for ecology and the environment. An analysis of the scientific literature indicates that the solution to this problem is seen in the use of biopolymers or their combination with environmentally friendly fillers [1][2][3][4][5].…”

Natural fibers and biodegradable matrices are currently being considered as substitutes for synthetic fiber-reinforced polymer composites mainly in areas where high load-bearing capacity and high strength are not essential. This study compares a biodegradable wood-polymer composite (WPC) prepared by varying the weight of the base material PHB and a wood flour binder as reinforcement at a weight ratio of 50/50 and 60/40%, as well as a binder made of a high-density polyethylene with wood flour at identical ratios. The maximum flexural strength of 19.193 MPa was obtained using a 50/50 combination of PHB and wood flour. The maximum value of tensile strength was shown by composites of polyethylene with wood flour at a ratio of 60/40. The maximum values of impact strength were shown by composites with a lower filler content. The highest water absorption was shown by composites from the biodegradable PHB binder. Thus, the analysis of the results showed that not only the content of the filler, but also the matrix itself has the maximum effect on the strength characteristics.

“…The theoretical sugar recovery reaches 65-70%. In order to increase the efficiency of using plant raw materials and create a waste-free technology, it is advisable to use both the sugars isolated during hydrolysis, and the solid residue [20][21][22][23][24][25].…”

Use of Filled Bioplastics in Construction

Polymers and associated composite materials play an increasingly prominent role among structural materials. The relevance of the use of bioplastics as an alternative to synthetic polymers increases year by year. In this regard, the paper describes the production of a ligno-filled polymer material based on polyhydroxyalkanoates to be used in the production of building materials. The studies allowed us to produce the material from wood hydrolyzates. The highest yield of reducing substances in course of pine sawdust hydrolysis with 4% sulfurous acid occurred at 170°C. To obtain a biopolymer in liquid wood hydrolyzate medium, the Cupriavidus necator strain was used, which after 50 hours of cultivation gave a biopolymer yield of up to 15 g/l. The studies of the strength characteristics of the composite based on the obtained bioplastic and dried solid wood hydrolysates allowed us to produce a balanced composition for subsequent use in construction.
