Method for characterizing regeneration effect of waste thermosetting plastic

The invention discloses a method for characterizing a regeneration effect of waste thermosetting plastic. The method is characterized by comprising the following steps: crushing and regenerating thermosetting plastic to obtain regenerated materials; grouping raw materials of the thermosetting plastic and the regenerated materials with different granularities into each powder group; testing the cross-linking density of each powder group; recording the minimum value of the cross-linking density; mixing each group of the regenerated material in each powder group with thermoplastic resin according to a set mass ratio; adding a chemical auxiliary agent for hot press molding to prepare a regenerated plastic product; preparing the regenerated plastic product into a sample and testing the mechanical strength; determining a regeneration coefficient gamma; and determining a quantitative index of the regeneration effect and judging that whether the regenerated powder reaches the index or not. The invention provides the
