| Title of the article | The influence on the properties of metal hydroxides PVC-composition |
| Abstract. | We have studied the effectiveness of flame retardants in the composition of plasticized polyvinyl chloride compositions, intended for processing by extrusion, which was carried out on a twin screw extruder. The influence of fire retardants on the flammability of composites on the physical and mechanical properties, are set depending on the concentration of flame retardants, the degree of dispersion and hydrophobicity. It was found that with increasing content of flame retardants in all indicators of fire resistance of their efficiency is improved, while self-combustion was reduced by an average of 65 %. Indeed, it was found that an increase in the content of flame retardant fillers leads to a natural reduction in the mechanical properties. However, the samples containing aluminum hydroxide and magnesium hydroxide with a small particle size quite satisfy the requirements of plasticized PVC containing 30-40 pbw plasticizer. Thus, in the production of film-based materials calendering PVC plasticized-retardants is desirable to use fillers with a minimum grain size (20 and 40 microns). All the used flame retardants can be recommended as PVC excipients, including most likely hard and products where no such role antiperiruyuschaya schematic. |
