Abstract: Amidated melamine film and hard foam materials were prepared from amidated melamine resin,
which was synthesized from addition and polycondensation reaction of amidated melamine, formaldehyde,
mixed alcohols and other additives with amidated melamine produced from stearyl chloride amidation. The
structure and properties of amidated melamine, amidated melamine resin, thin film and rigid foam materials
were then characterized by FTIR, NMR, TG , SEM and EDS. The results showed that the introduction of
hydrophobic alkyl long chain increased the contact angle of amidated melamine from 0° to more than
133.5°. With the amination degree increased, the water tolerance point temperature of amidated melamine
resin decreased gradually, while the viscosity and the insoluble particles displayed a contrast trend.
Compared with conventional melamine resin, the amidated melamine resin (whether films or hard foam
materials) didn’t show significant reduction in mechanical properties. The compressive strength of sample
was up to 39.5 MPa, the bending strength of the rigid foam material was up to 345.8 kPa and the
compression strength was up to 315 kPa. Meanwhile, the amidated melamine resin exhibited excellent
water resistance and hydrophobic effect. The water absorption rate was only 1.1% at 24 h, the volume water
absorption rate of the rigid foam reduced to 2.0%, the water contact angle of the film increased to 107.5°,
