摘要:
This invention relates to a solventless polyurethane no-bake foundry binder system comprising, as individual components (a) a polyol component comprising a polyether polyol, glycol, and an aromatic polyester polyol, (b) an organic polyisocyanate component, and (c) a liquid tertiary amine catalyst component. Foundry mixes are prepared by mixing the binder system with a foundry aggregate by a no-bake process. The resulting foundry shapes are used to cast metal parts from ferrous and non-ferrous metals.
摘要(中):
本发明涉及无溶剂聚氨酯无烘烤铸造粘合剂体系,其包含作为单独组分(a)包含聚醚多元醇,二醇和芳族聚酯多元醇的多元醇组分,(b)有机多异氰酸酯组分,和(c) 液态叔胺催化剂组分。 通过无烘烤工艺将粘结剂体系与铸造体组合物混合制备铸造混合物。 所得到的铸造形状用于从黑色金属和有色金属铸造金属部件。
