Polypropylene (PP) is currently the second largest general-purpose plastic. With the development of industries such as construction, automobiles, home appliances and packaging, waste PP has become one of the largest waste polymer materials in recent years. At present, the main ways to deal with waste PP are: incineration for energy supply, catalytic cracking to prepare fuel, direct utilization and recycling. Considering factors such as technical feasibility, cost, energy consumption and environmental protection in the process of processing waste PP, recycling is the most commonly used, effective and most advocated way to deal with waste PP.
Due to the influence of factors such as light, heat, oxygen and external force during use, the molecular structure of PP will change, and the product will become yellow, brittle, or even cracked, resulting in PP toughness, dimensional stability, thermo-oxidative stability and workability. It is obviously worse, and it is difficult to directly use waste PP to manufacture products to meet the requirements of processing and use.
Therefore, the recycling technology of waste PP continues to develop. Alloying with other polymers or compounding with fillers can significantly improve the processing performance, thermal properties, physical and mechanical properties of waste PP, and realize the high performance of waste PP.
