[0002] The process of coated sand is to mechanically mix powdered thermosetting phenolic resin with raw sand and solidify it when heated. Later, it developed into using thermoplastic phenolic resin plus latent curing agent (urotropine) and lubricant to prepare coated sand through a certain coating process. When the coated sand is heated, the resin coated on the surface of the sand particles melts. Under the action of the methylene group decomposed by urotropine, the molten resin quickly changes from a linear structure to a non-melting body structure, thereby solidifying and forming the coated sand.
