Description

一种防火装饰石膏板及其生产方法
技术领域
本发明涉及建筑用装饰板材，具体为一种防火装饰石膏板。
背景技术
目前，石膏板以其质轻、成本低、隔音、隔热的特点成为备受关注的新兴建筑装饰材料，但是国内装饰石膏板生产，大多以石膏粉为原材料，经过压花滚筒搅拌成型后压花，虽然具有精美的图案，但是板强度差，防火性能一般；吊顶后容易下垂，其易脆抗形变能力差的缺点使其应用受到一定的限制，目前市场上的防火板材为了提高装饰板的强度及抗火性能，一般采用内附钢骨或者贴附防火纤维毡等方式，这样的板材不仅成本高，且生产工艺复杂，吊顶重量大，装饰施工速度低，因此目前的防火类装饰板产品质量及生产工艺存在较大的缺点。
发明内容
本发明的目的就是要提供一种造价低、使用方便、强度高、耐热防火性能高的防火装饰石膏板及其生产工艺。
本发明的技术目的是这样实现的：一种防火装饰石膏板，包括铝箔、纸面石膏板、压花浮雕，铝箔贴附在纸面石膏板背面，压花浮雕为树脂、CaCO3按照3∶1组合而成防火涂料，喷涂在纸面石膏板正面，所述纸面石膏板，其原料配比为：58份的脱硫石膏建筑石膏粉，5份的变性淀粉，1份的发泡剂十二烷基硫酸钠，2份的玻璃耐火纤维，34份水。
一种防火装饰石膏板的生产方法为：将纸面石膏正面朝上在辊道输送下，经过滚花压筒，对纸面石膏板压花速度为16m/min，经过棕刷表面清洁后，由喷涂机进行专用耐火乳胶涂漆两遍，第一遍喷涂后初步干燥，再进行二次喷涂，最终形成具有平均厚度2.5mm的涂料层；与喷涂同步，施胶机在纸面石膏板背面进行施胶，厚度1.5mm的铝箔在纸面石膏板施胶后进行背后贴膜，经过喷涂与贴膜的纸面石膏板，以20m/min的速度进入电热烘干箱内，在温度为90℃-120℃下，经过1小时烘干，干燥后既得本发明产品。
通过压花、涂漆烘干后的纸面石膏板不仅提高了装饰板抗形变能力及抗火能力，同时本防火装饰石膏板结构简单、施工方便、生产造价低，强度高，具有推广意义。
附图说明
图1为本发明实施例剖面结构示意图。
具体实施方式
如图中所示：一种防火装饰石膏板，包括铝箔1、纸面石膏板2、压花浮雕3，铝箔1贴附在纸面石膏板2背面，压花浮雕3为树脂、CaCO3按照3∶1组合而成防火涂料，喷涂在纸面石膏板2正面，所述纸面石膏板2，其原料配比为：58份的脱硫石膏建筑石膏粉，5份的变性淀粉，1份的发泡剂十二烷基硫酸钠，2份的玻璃耐火纤维，34份水。
防火装饰石膏板的生产方法为：将纸面石膏板2正面朝上在辊道输送下，经过滚花压筒，对纸面石膏板2压花速度为16m/min，经过棕刷表面清洁后，由两部喷涂机进行专用耐火乳胶涂漆两遍，第一遍喷涂后初步干燥，再进行二次喷涂，最终形成具有平均厚度2.5mm的涂料层；与喷涂同步，施胶机在纸面石膏板2背面进行施胶，厚度1.5mm的铝箔1在纸面石膏板2施胶后进行背后贴膜，经过喷涂与贴膜的纸面石膏板2，以20m/min的速度进入电热烘干箱内，在温度为90℃-120℃下，经过1小时烘干，干燥后进入纵向锯切机，然后转角进行横向锯切，形成基本尺寸600×600(mm2)的防火装饰石膏板制品，最后经过周边塑料包膜后下线。
铝箔1的具有降噪、隔热反热辐射的特点，石膏板具有遇热释放水蒸气的特点，内填充有防火纤维纸面石膏板2具有的防火性能，耐火涂料和铝箔1贴膜的组合使得板材防火性能进一步加强。
本实施例产品与现有防火类装饰板产品性能主要指标对比如下：
