Research on Synthesizing Phenylic Phenolic Resin of Foundry Binder System

Abstract:

Resin in the foundry polyurethane binder is asked to be phenylic phenolic resin.The composition of the resin influences the capability of the polyurethane binder.In this paper.We studied on the synthesizing phenylic phenolic resin and obtained the better optimal technology conditions as following: used feculent point （80~90°C）to terminate the experiments;the optimal molar ratio of phenol to formaldehyde is from1∶1.5 to 1∶1.75;the formaldehyde concentration is 50%;the amount of catalyst is 0.05%~2% of the phenol.Phenylic phenolic resin that we get can enhance the strength of foundry cores and molds obviously.
