Description

一种后置式结构防火保温板及其连续生产工艺
技术领域
本发明涉及一种后置式结构防火保温板及其连续生产工艺，属于建筑材料结构及其生产方法技术领域。
背景技术
岩棉作为具有A级阻燃性能的传统保温材料被广泛应用于外墙外保温领域，硬泡聚氨酯作为保温效果最好的新兴材料在外墙外保温领域极具发展前景。公告号为：102700227A，名称为夹芯板生产系统及其生产方法，该专利提供了一种夹芯板的生产方式，即在岩棉板上下两侧复合彩钢板；公告号为：202556821U，名称为：聚氨酯复合材料制品，该专利提供了一种聚氨酯复合材料制品，它包括上玻纤聚氨酯层和下玻纤聚氨酯层，其特征是，在上玻纤聚氨酯层和下玻纤聚氨酯层之间设有低密度聚氨酯泡沫夹芯层。这两种不同形式的保温装板，前者阻燃性能较好，但导热系数较高；后者阻燃性能一般，但保温性能优异，为充分发挥复合材料的优势，后置式结构防火保温板应运而生。
发明内容
本发明的目的在于解决上述现有技术存在的不足之处，提供一种产品质量稳定，保温性及防火性能好，产品安全可靠，工艺简便易行，生产效率高的后置式结构防火保温板及其连续生产工艺。
一种后置式结构防火保温板，其特殊之处在于包括起增强及防火作用的上卷材层8、下卷材层6，上卷材层8与下卷材层6之间设有起防火及保温作用的岩棉板2、起保温作用的聚氨酯泡沫层14，上卷材层8、下卷材层6、岩棉板2、聚氨酯泡沫层14复合为一体，后置式结构防火保温板的四周设有防水涂层16；
所述上卷材层8、下卷材层6是由阻燃型聚合物胶浆制备而成的界面片材，其基材为玻纤、网格布、无纺布中的任意一种。
一种后置式结构防火保温板的连续生产工艺，其特殊之处在于包括以下工艺步骤：
1）、将聚氨酯组合料的A料和B料加入组合料储料系统7，将胶粘剂加入喷胶机储料系统3，备用；
