Abstract: A kind of polyester polyol isocyanate prepolymer interface compatibilizer is synthesized and successfully used in the preparation of biomass-waste plastics composites from corn straw meal and spent polypropylene.Suitable synthetic process conditions are explored,and the morphology,mechanical properties and thermal properties of the interface compatibilizer are characterized by scanning electron microscopy (SEM),thermogravimetric analysis (TG),Fourier transform infrared spectroscopy (FT-IR),etc.It is shown that the compatibilizer can effectively improve the compatibility between biological waste powder and PP.As compatibilizer content is 5.0 wt%,the maximum bending strength of the composites reaches 43.26 MPa,compared with the 34.83 MPa of the composites without the compatibilizer;and the tensile strength of the composites reaches 23.06 MPa,compared with the 15.70 MPa of that without the compatibilizer.Addition of the compatibilizer improves the thermal stability and water resistance of the composites.It is shown that this new type of compatibilizer exhibits moderate price,less dosage add higher compatible efficiency and other characteristics,which can solve the problems of current compatibilizers available.
