| titleOfInvention | Resin coated sand grain for shell mold |
| abstract | PURPOSE: To obtain a molding material for a shell mold having an excellent collapsing property after casting by coating a binder consisting of a phenolic resin and phenylphosphonous acid compd. on the surface of molding sand thereby constituting resin coated sand grains. n CONSTITUTION: The binder consisting of the phenolic resin and phenylphosphonous acid compd. is coated on the surface of the molding sand to form the resin coated sand grain for the shell mold. The phenylphosphonous acid compd. is the compd. expressed by the general formula (where R 1 and R 2 are a group selected from a hydrogen group, alkyl group of 1W5C and phenyl group). The desirable phenolic resin is a solid resol resin and the phenylphosphonous acid compd. is used at a ratio of 0.5W7pts.wt. per 100pts.wt. phenolic resin. The molding material for the shell mold having the excellent collapsing property after casting is thus obtd. n COPYRIGHT: (C)1987,JPO&Japio |
