Апстракт:
In this paper, the upcycling of recycled polypropylene with the addition of waste paper, appropriate compatibiliser, lubricant and antioxidant is presented. In the research work, compounding was performed on the twin-screw extruder. The addition of waste paper varied from 5 wt.% to 30 wt.% in the 5 wt.% steps. To improve the compatibility between the paper and rPP, the graft copolymer PP-g-MA was added in a concentration of 4 wt.%. The research proved, that good homogenisation was achieved with addition of lubricant, and the oxidation was prevented with addition of antioxidant. For the characterisation purposes, the test speciments were prepared by injection moulding, according to ISO 527 (form 1BA), ISO 178 and ISO 179. The results of tensile and bending tests proved that E modulus increased significantly with addition of 30 wt.% waste paper. Tensile and bending strength increased up to 41 %, as well. The results of DMA tests showed the same tendency. With the research it was proved, that with addition of more than 20 wt.% of waste paper, strength and storage moduli increased, while the impact strength practically remained unchanged. The research results proved, that composite is industrial applicable since high compatibility was achieved.
