Abstract :Discarded corn husk fibers/ polylactic acid composites containing ammonium polyphosphate and pentaerythritol as flame retardants were prepared by blended hot mastication process． The factors affecting the results were hot processing temperature, time, and pressure, mass fraction of discarded corn cob husk fibers made by flame retardant treatment, etc. Under the optimal technology conditions, the flame retardancy and mechanical properties were determined as follows: limiting oxygen index was 35.2 %; bending strength was 84 MPa; tensile strength was 40 MPa; impact strength was 6.4 KJ/m2. The flame retarded composites made of pre-treated corn husk fibers and polylactic acid with good flame retarded and mechanical properties could be used in building materials, furniture, decorative materials and other fields.
Keywords : Discarded corn husk, flame retardant treatment, polylactic acid, composites， flame retarded properties, mechanical properties
