Preparation and Properties of Tapioca Starch-Banana Fiber Composites Modified with Magnesium Hydroxide

Abstract:

Banana fiber/tapioca starch (BFRTPS) composites modified by magnesium hydroxide (Mg(OH)₂) were prepared with glycerin as the plasticizer, banana fiber as reinforcement and thermoplastic tapioca starch as matrix. Rheological properties testing showed that Mg(OH)₂ take a strong effect to the preparation processing and made it hard to mix while the content increasing. Mechanical properties testing revealed that at the range of the Mg(OH)₂ content from 5 to 20phr, the tensile strength of the composites increased from 12.8MPa to 24.8MPa at 15phr Mg(OH)₂ content, but its elastic modulus was increased with the increasing of Mg(OH)₂, reached the maximum of 3100MPa at 20phr Mg(OH)₂ content. Obviously, Mg(OH)₂ has an enforced effect to the composites. Combustion performances of the composites was improved by Mg(OH)₂, the limited oxygen index(LOI) of the composites reached to 31% while the content of Mg(OH)₂ was 20phr, and then the result of flammability testing achieved UL94HF-1 and UL94 V-0 level.
