Abstract
PURPOSE: To impart a cellulosic material with excellent flame-retardancy together with high thermal stability, without lowering the characteristics of the cellulosic material, by compounding the material with a sulfonic acid group- containing modified condensate of melamine/dicyanodiamide/aldehyde.
CONSTITUTION: A cellulosic material is mixed with a sulfonic acid group-containing condensate of melamine/dicyanodiamide/aldehyde, preferably the condensate obtained by reacting the three components in an aqueous solvent at a (melamine):(dicyanodiamide) molar ratio of 1:(0.2W3), (melamine+dicyanodiamide): (aldehyde) molar ratio of 1:(1W6) and (aldehyde):(sulfonation agent) molar ratio of 1:(0.1W1). An additive effect can be attained by the addition of acids, guanidine, guanylurea, and ammonium salt-type flame retardant. The flame retardant treatment is preferably carried out by using a 7W60wt% aqueous solution in an amount to give 5W40pts.wt. of the flame retardant to 100pts.wt. of the cellulosic material.
