Binder System For Reduced Metal Mold Reaction

A binder system for refractory materials used in sand casting processes, especially two-part polyurethane-based binder systems used in the cold box or no bake process, has less metal-mold reaction when a separate third part is used. The third part is an alkyl silicate, such as tetraethyl orthosilica...

Summary:A binder system for refractory materials used in sand casting processes, especially two-part polyurethane-based binder systems used in the cold box or no bake process, has less metal-mold reaction when a separate third part is used. The third part is an alkyl silicate, such as tetraethyl orthosilicate ("TEOS"), an alkyl orthoformate, such as trimethyl orthoformate (TMOF) or triethyl orthoformate (TEOF), or combinations thereof. 当使用单独的第三部分时，用于在沙子铸造过程中使用的耐火材料的粘合剂体系，尤其是在冷芯盒或无烘烤过程中使用的两部分聚氨酯类粘合剂体系的金属-模具反应较少。第三部分是硅酸烷基酯诸如原硅酸四乙酯("TEOS")、原甲酸烷基酯诸如原甲酸三甲酯(TMOF)或原甲酸三乙酯(TEOF)或它们的组合。
