the recycled thermosetting flour composites and method for preparing the same are disclosed . the silane coupling agent is used as a coincidental bridge between recycled thermosetting flour and plastic materials , to apparently promote the mechanical properties of composites by linking with each other . as a result , the recycled polyolefin and recycled thermosetting flour are applied through interfacial modification , coupling , modification , mixing and granulating process to generate a composite with better mechanical properties and recycle the resource .
