The synthetic technology conditions of urea-formaldehyde resin with low free formaldehyde were studied. The urea-formaldehyde resin was modified by using melamine,polyvinyl alcohol and etherification to reduce the content of free formaldehyde, maintaining its stability and stiffness effects. The factors including formaldehyde/urea molar ratio, reaction temperature, and pH value to the effects of urea-formaldehyde synthesis performance were discussed. The configuration and performance were… CONTINUE READING
