摘要：

Intumescent flame retardant thermoplastic starch (TPS) as char forming agent, ammonium polyphosphate (APP) and expandable graphite (EG) were used to prepare thermoplastic starch/ethylene-vinyl acetate copolymer (TPS/EVA) foam composites by melt mixing, mill plasticizing and sulfuration foaming. The effect of thermoplastic starch content on the flame retardant, mechanical and processing properties of TPS/EVA foam composites was investigated. With the introduction of char forming agent TPS, flame retardancy and charring of TPS/EVA foam composites could be significantly improved. With increasing TPS content, tensile strength, elongation at break and tearing strength of TPS/EVA foam composites showed a downward trend after firstly rising and specific gravity showed a modest rise. The TPS/EVA foam composites had best comprehensive properties at the loading of 6%TPS, i.e. LOI 26.5%, UL-94 V-0 rating, tensile strength, elongation at break, tearing strength and specific gravity 2.395 MPa, 177.48%, 10.59 N·mm-1, 0.21452, respectively. ©, 2015, Chemical Industry Press.
