摘要: A material for a mold of the invention contains as a major component a refractory aggregate and a curable binder containing a polyfunctional acrylamide having two or more ethylenically unsaturated groups per molecule. This material is excellent in low-temperature fast-setting properties, degradation resistance and working life, and is particularly suited as a mold material for casting a low-melting metal such as aluminum alloy.
摘要翻译: 的模具材料包括作为主要成分,一个耐火骨料(100重量份)和固化性粘合剂(1)(重量份0.3-5,优先。0.5-3重量份)。 (1)含有具有两个或多个烯unsatd的多官能丙烯酰胺(-50重量%或更多,优先。70重量%或更多,最好90%(重量)或更多)。 GPS。 每摩尔。 (1)包含选择。 具有一个烯unsatd单官能丙烯酰胺。 GP。 和/或一种其他烯unsatd。 CPD。 :如环氧树脂,三聚氰胺树脂,氨基甲酸乙酯,呋喃CPDS。 和反应电棒。 的合成。 多官能丙烯酰胺是CPDS之一。 由通式(I),(II)和(III)表示,其中R是氢或1-5C烷基GP。 因此,模具材料可以包含硅烷偶联剂,固化进展试剂,其包含聚合引发剂或混合。 聚合的进展试剂和聚合引发剂,和聚合引发剂。
