The effects of mole ratio of formaldehyde and melamine (F/M),solution pH,reaction temperature (T) and time (t) on the properties of foaming melamine-formaldehyde (MF) resin with caprolactam as modifier were investigated by orthogonal experiment where solid content,viscosity and storage time of the MF resin,density and size uniformity of the MF foam were used as performance evaluation parameters. The results of the experiments were analyzed by using the comprehensive scoring method and the integrated balance method. The optimum formula of prepar...
