Title of the articleWood-polymer composites based on polyvinylchloride modified by amorphous silica
Abstract.In the work investigated the use of aerosil (amorphous silica) as coupling agent for wood filled PVC formulations to improve the interfacial interaction between PVC and wood flour. Samples were prepared by extrusion on a twin screw extruder. Studied the effect of aerosil on technological, physical, mechanical and performance properties of the composites. It is shown that its use leads to a slight difficulty processing composition, namely increasing the melt pressure in the die from 51 to 57 bar and the engine load greater than 2 times. However, the optimal concentration of aerosil in composites (0,75 phr) causes an increase in strength of the composites by 27 %, reducing their water absorption is 2,3 times, and flammability. Thus, the modification of wood-polymer composites based on PVC by aerosil is more efficient compared with previously used coupling agent (silica sol) is not optimum, only the improved properties of composites, but also processability, requiring no modification changing the existing for their manufacture.
Keywords.wood-polymer composite, polyvinylchloride, amorphous silica, extrusion, flammability.
