Abstract
The invention relates to reinforced and toughened modified regenerated PP plastic particles and a preparation method thereof. The plastic particles are prepared from the following components, by weight: 40-50 parts of PP which is polypropylene, 5-8 parts of a toughening agent which is POM, PVC, PET or PETG, 25-30 parts of a reinforcing agent which is glass fiber, organic fiber or asbestos, and 10-15 parts of a modification agent which is wollastonite or precipitated barium sulfate. The preparation method provided by the invention adopts contemporary latest plastic modification theories which are plastic multi-element composite modification, elastomer toughening, and inorganic filler toughening and reinforcing technologies. Regenerated homopolymerized PP is adopted as a main material, and is toughened and reinforced with the toughening agent, the reinforcing agent and the modification agent. As a result, POM, PVC, PET or PETG has a good toughening effect; glass fiber, organic fiber or asbestos has a good reinforcement effect; and wollastonite or precipitated barium sulfate has a good modification effect. The strength and toughness of PP are improved; various physical and mechanical performances reach design requirements; material comprehensive performance is improved; and production cost is reduced.
