Abstract
本发明提供了一种基于改性聚氨酯的环保型金属面夹芯板。该技术方案首先分析了聚氨酯保温材料的成分特征，在此基础上对其配方进行了创新性改进。具体来看，本发明以聚己内酯多元醇、聚碳酸酯二醇和二羟基聚醚共同构成聚酯多元醇成分，以3‑乙基苯基异氰酸酯、2,2'‑亚甲基二苯基二异氰酸酯复配构成脂环族异氰酸酯成分，不仅实现了聚氨酯的化学改性，而且提升了安全性和环保性。此外，本发明添加了N‑邻苯二甲酰甘氨酸、邻苯二甲酸二环己酯等成分，有助于提高聚氨酯的发泡效果，从而改善芯材的保温性能。本发明不仅配方合理，而且制备工艺相对简单，工艺流程较短，成本较低，充分提高了生产效率，具有突出的技术优势。
Description
技术领域
本发明涉及建筑板材技术领域，具体涉及一种基于改性聚氨酯的环保型金属面夹芯板。
背景技术
金属面夹芯板是指上下两层为金属薄板，芯材为有一定刚度的保温材料，如岩棉、硬质泡沫塑料等，在专用的自动化生产线上复合而成的具有承载力的结构板材，也称为三明治板。夹心板的表层用材常见的有胶合板、纤维板、塑料板和金属薄板；芯材有轻木、橡胶、醋酸纤维、塑料和经树脂浸渍(或不经浸渍)的纸质或布质以及金属的蜂窝结构材料。
夹心板的表层材料对其物理性能和环境耐受性具有更重要的影响，而芯材则决定着夹芯板的保温、隔音等性能。芯材是具有一定大小的蜂窝状孔格结构材料。通常将牛皮纸逐张用特制的涂胶设备单面滚涂胶料，相邻层纸上涂胶部位错开其距离为两胶条间距的一半，涂胶线宽度为正六角形一边的长度。纸张叠合胶粘成垛，继用铡刀切成一定宽度，然后加热使胶液凝固，将两端拉开，即成六角形蜂窝结构。近年来，以聚氨酯保温材料为芯材的保温板得到了越来越广泛的应用。聚氨酯保温材料是一种性能优良的合成材料，它具有比强度高、导热系数小等优点。然而，目前常规聚氨酯芯材的环保性仍不理想，在生产过程中对环境存在一定污染，而且长时间使用过程中会产生一定的挥发性成分，对人体健康具有潜在影响。
