AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained fromwaste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the producedsilica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigatethe mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization ofcomposite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) andmeasurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles withvinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and loadfor comparison of measurements between different composite materials and to enable the choice of the material in terms ofoptimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double hydroxides are materials that are easily synthesized by several techniques giving the possibility to modulate the chemical composition and morphology of the reinforcement and they consist of a divalent and a trivalent anion hydroxide and the layers can be exfoliated and thus provide a material interesting for composite reinforcement. In this paper, Mn was used as a divalent and Al as a trivalent cation. The obtained particles were used as reinforcement for the preparation of composites in 1, 3, and 5 wt% quantities and prepared samples were compared to the matrix consisting of PMMA. Physical mechanical properties of the sample having the best mechanical properties (with 3 wt% of MnAl-LDH filers) exhibited 6.38% modulus of elasticity, 27% hardness, and 10% tensile strength improved values compared to the clear PMMA matrix. Toughness was lowered in this sort of composite compared to the pure matrix. Highlights: MnAl-LDH-PMMA composites improved modulus, strength, hardness Loss of toughness is tolerable for 3 wt% reinforcement Viscoelastic properties are improved for composites compared to matrix.

AB  - Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linterscross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystalviolet (CV) removal, was performed. Adsorption data fitting, obtained using the Langmuir model, gave116 mg g 1 (Pb2+), 179 mg g 1 (MB) and 482 mg g 1 (CV) at 25 ℃ for TOCell linters, while 101 mg g 1(Pb2+), 165 mg g 1 (MB) and 426 mg g 1 (CV) for TOCell membrane. After desorption dyes were subjectedto photocatalytic degradation while lead was transformed into stable lead phthalate (LP), and furtherused as filler in composites based on unsaturated polyester resins (UPR). UPR was synthesized fromwaste polyethylene terephthalate (PET). Structural characterization was performed using FTIR, SEM,and NMR methods. Composites loaded with acryloyl modified kraft lignin (A-KfL) and/or LP was testedfor tensile strength, Vickers microhardness, and fire resistance (UL-94 V method). The best mechanicaland fireproofing properties were obtained at 15 wt.% A-KfL and 40 wt.% Al(OH)3 addition. The resultsof the toxicity leaching test (TCLP) confirmed the environmentally safe stabilization of desorbed pollutantin the UPR matrix. Application of environmentally friendly membranes, susceptible to easy biodegradation, had low negative effects to the environment.

AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol(PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained fromrice husk. The structural and morphological properties of the obtained particles, b-UPR, as well ascomposites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magneticresonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electronmicroscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanicalproperties of composites was supported by hardness modeling. Improvement of the tensile strengthof the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named“b-UPR/SiO2-V” composite, has been achieved with 88% increase. The thermal aging process appliedto the b-UPR/SiO2-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR).The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of atable top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, aswell as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainablecomposites that are chemically synthesized from renewable sources is important from the aspect ofpreserving the environment and existing resources as well as the extending their life cycle.

AB  - Predmetni pronalazak opisuje novi protivpožarni materijal koji se koristi za proizvodnju cevnih prstenova kao pasivne zaštite od širenja vatre. Tehnološki proces se sastoji od dve faze. Prva faza uključuje mešanje poli(vinil-hlorida) ili poli(vinil-hlorida-co-vinil-acetata) kopolimera ili modifikovanih poli(vinil-hlorida-co-vinil-acetata) kopolimera sa plastifikatorima/modifikatorima, poput: ftalatnih plastifikatora, npr. diizononil ftalat - DINP, dioktil-adipat - DOA, 1-heksadecen ili metil ester masnih kiselina, azodikarbonamid (ADC), tri(kresil fosfat), plastifikatori na bio-osnovi (estri 2,5-furandikarboksilne kiseline i furan-2,5 diildimetanola), epoksidirano sojino ulje (ESU) i akrilna emulzija prema definisanoj tehnologiji korišćenjem toplog miksera. Druga faza uključuje dodavanje ekspandiranog grafita homogenizovanoj masi i obradu prema optimizovanoj tehnologiji korišćenjem ekstrudera i profiliranja u definisanoj dimenziji debljine traka od 4 - 6 mm, širine 70 - 400 mm i dužine 240 - 500 mm kao konačnog proizvoda.
AB  - The present invention describes a novel fire-retardant material used for the manufacture of pipe rings as passive protection against the spread of fire. The technological process consists of two phases. The first phase involves mixing of poly(vinyl chloride) or poly(vinyl chloride–co–vinyl acetate) copolymers or modified poly (vinyl chloride–co–vinyl acetate) copolymers with plasticizers/modifiers such as: phtalate type plasticizer, e.g. diisononyl phthalate – DINP, dioctyl adipate - DOA, 1-hexadecene or methyl esters of fatty acids, azodicarbonamide (ADC), tri(cresyl phosphate), bio-based plasticizers (ester of 2,5-furandicarboxylic acid and furan-2,5-diyldimethanol), epoxidized soybean oil (ESU) and acrylate emulsion accoridng to defined technology using hot mixer. The second stage involves addition of expanded graphite to homogenized mass and processing according to optimized tecnology using extruder and profiling at defined dimension of 4 - 6 mm thick, 70 - 400 mm wide and 240 - 500 mm long sheet as final product.

AB  - The present invention is a novel fire-resistant material used for the manufacturing of pipe collars as passive fire protection. The technological process consists of two phases. The first phase involves mixing poly (vinyl chloride-co-vinyl acetate) copolymers (VC-co-VAc) or a modified poly(vinyl chloride-co-vinyl acetate) copolymer (VC-co-VAc) with expandable graphite and plasticizers/modifiers such as: diisononyl phthalate - DINP, dioctyl adipate - DOA, 1- hexadecene or methyl esters of soybean fatty acids (MBS), azodicarbonamide (ADC), tri-p- cresyl phosphate, tri-m-cresyl phosphate or tri-o-cresyl phosphate, epoxidized soybean oil (ESO) and polyacrylate or poly(vinylacetate) emulsion. The second phase considers shaping the resulting mixture in a temperature-controlled press to make various samples, which are further tested. The samples had different dimensions: 4 - 6 mm thickness, 70 - 400 mm width and 240 - 500 mm length.
