Development of Halogen-free Composite Liquid Flame Retardant and Application of Flexible Polyurethane Foam
The paper compares the performance of the mainstream liquid flame retardant in the market with the self-developed flame retardant EPPE,and develops a halogen-free composite liquid flame retardant through the selection and evaluation of liquid flame retardant,the selection and evaluation of anti core burning agent,and the determination of the addition amount of anti core burning agent.With 10 portions of the composite liquid flame retardant,the Q(A)flame retardant grade of FMVSS-302 and XF303-2001(soft flame retardant polyurethane foam)can be passed.The mainstream liquid flame retardants B and A can only achieve the same flame retardancy level by adding more than 15 parts.The composite liquid flame retardant has a small amount of addition and good flame retardancy,which has good market promotion prospects.
