Abstract: By using a specific composition of solvent oil and subjecting the recycled waste plastic particles produced by a domestic waste plastic processing plant to liquefaction treatment under the conditions of a certain temperature and stirring rate, the liquefaction rate of recycled waste plastic particles in the specific solvent oil and the viscosity of waste plastic liquefied liquid were measured, and the correlation formula between the viscosity of waste plastic liquefied liquid and the concentration of recycled waste plastic particles was established. The experimental results demonstrated that the mass fraction of recycled waste plastic particles in the waste plastic liquefied liquid is the main factor affecting the liquefaction rate of recycled waste plastic particles and the viscosity of waste plastic liquefied liquid.
