Treść
The use of fillers in the production of plastic products is intended to improve their properties, the wider use and reduce prices. The ageing of polymers results in deterioration of strength properties of the material. Forecasting changes caused due to ageing allows to determine the feasibility of application of the composites under certain conditions. The article presents the results of investigations of polyethylene (Hostalen 7260, Lyondellbasell) with cardboard and dye composites before and after electrochemical ageing. Ageing process was performed in special chamber, in water solution of NaCl (35‰) at pH 7 and at 20°C for 720 h (current 0.3 A). Samples with the addition of 2% dye, 2% dye and 2% cardboard, 2% dye and 4% cardboard, 2% dye and 6% cardboard were tested. The carboard filler was made by mechanical fragmentation. The samples were injected using a KraussMaffei KM65-160C1 injection moulding machine. Tensile strength was measured. The thermal properties were analysed using a DSC method. Structure was observed using light microscope. Hardness was determined with ball pressing method. The aim of the investigations was to determine the influence of the filler on the composite properties and to receive a new, cheaper material. Changes in the degree of crystallinity, the melting point range, structure of the tested materials were revealed. The changes in mechanical properties of polyethylene with filler and dye before and after ageing were observed. The studies show that the electrochemical ageing causes significant changes in the properties of the tested materials.
