聚双酚酸苯基磷酸酯的合成及其与APP协同阻燃EVA的研究
Synthesis of a novel polyphosphate and its synergism with APP in flame retardant EVA
摘要
Abstract
A novel phosphorus-containing flame retardant, poly(DPA-PDCP), was synthesized by interfacial poly-condensation from DPA(diphenolic acid), a compound can be produced from biomass. The effects of reaction time, tetrabutyl ammonium chloride dose and NaOH dose on yields were analyzed. The experiment results showed that the optimum reaction conditions are as follows: T=25 ℃ , nTBAC:nDPA= 4%, nNaOH :nDPA=3, 1 h. The yield of the product was about 75%. Poly(DPA-PDCP) has good synergism with ammonium polyphosphate (APP) in flame retarding EVA. An LOI value of 25% can be achieved when the total loading of poly(DPA-PDCP)/APP(mass ratio= 4/1) was 30wt. %. The results of cone calorimeter indicates that the heat release rate (HRR) decreased by 62% when compared with those of neat EVA. TG curves showed that the initial decomposition temperature increased 32 ℃ and the amount of residues at 600 ℃ reached 27%. The results showed that the mechanism of poly(DPA-PD-CP)/APP is the solid-phase flame-retardant mechanism. Poly(DPA-PDCP) was carbon resource, when used togeth-er with APP existed distinet synergistie flame-ratardant effect.关键词
