Melamine Tableware is a high molecular polymer, abbreviated as MF, the monomer is formaldehyde and melamine. Reaction with 37% formaldehyde aqueous solution, formaldehyde and melamine two monomers molar ratio of 2 to 3. The results show that the amount of formaldehyde is increased with the increase of the amount of formaldehyde, the reaction is easy to be carried out. When the amount of formaldehyde is changed, the melamine resin obtained from different hydroxymethyl melamine can be prepared. When the reaction system has pH = 8.5, Less reaction is easy to control; high temperature, fast reaction speed, in the 54 ~ 80 ℃ range of formaldehyde on the amount of little effect.
