效果例
下表1给出了采用本发明实施例1、2、3与对比例1、2、3、4的热稳定抗形变保温板的各性能分析结果。
表1
通过表1中实施例与对比例的实验数据比较可以明显发现,实施例1、2、3制备的热稳定抗形变保温板的耐热性、抗压强度、与金属层的结合强度和剥离强度较好;
从实施例1、2、3和对比例1、2的实验数据比较可发现,利用羟基乙氧基萘与甲醛进行加成缩合反应,制成的酚醛树脂基体中含有萘和大量羟基,提高刚性,增强抗压强度,引入的一氯均三嗪衍生物上的羧基与酚醛树脂基体上的羟基反应,在酚醛树脂基体上引入更多的芳环,进一步增强抗压强度,同时一氯均三嗪衍生物还能够与酚醛树脂基体形成互穿聚合网络结构,纠缠在芳核之间,降低了酚醛树脂的脆性,增强了耐热性,一氯均三嗪衍生物上的磺酸基还能够与保温层反应,增强剥离强度;从实施例1、实施例2、实施例3和对比例3、4的实验数据比较可发现,在醇酸树脂上引入环氧基后,再与叠氮羟基噻烷反应,提高了保温层与酚醛树脂泡沫板的粘结性,环氧基还能够与叠氮羟基噻烷上的羟基反应,在保温层上引入叠氮基,增强保温层与金属层的附着力;保温层浆料上的羟基还能够与酚醛树脂泡沫板上的磺酸基反应,将保温层与酚醛树脂泡沫板紧密连接,增强剥离强度。
对于本领域技术人员而言,显然本发明不限于上述示范性实施例的细节,而且在不背离本发明的精神或基本特征的情况下,能够以其他的具体形式实现本发明。因此,无论从哪一点来看,均应将实施例看作是示范性的,而且是非限制性的,本发明的范围由所附权利要求而不是上述说明限定,因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何标记视为限制所涉及的权利要求。
