Abstract
PURPOSE: To insure the hot strength and disintegrativeness of titled molding sand, by coating the sand with double layers respectively comprising a phenol resin and a vinyl resin.
CONSTITUTION: Aqueous solution of polyvinylalcohol or polyvinylacetate possessing 400 or less mean polymerization degrees, is added to the silica sand by 0.1 or more weight precent as the solid solute; then, these materials are mulled by a sand mixer, and the surface of silica sand is coated by PVA or PVAc. This coating film is gelatinized by adding a monomer of boron compound or aqueous alkali solution of boron, for the purpose of intercepting the compatibility of the first coated film with the next coated film. The silica sand with gelatinized coating film is additionally coated by phenol resin, to finish the resin coated molding sand.
