矿棉吸声板已经研发出一套成熟的并且适用目前生产现状的覆膜喷砂生产工艺及系统。使用该技术系统生产出的覆膜喷砂矿棉吸声板具有外观品质高端、防潮性能优异、强度较高等优良特点，并且由于表面的细小砂粒可增加室内光线的漫反射，增加室内光线的柔和度。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请提供了一种覆膜喷砂矿棉板，其相比现有矿棉吸声板具有更高的防火性能，解决了现有技术中矿棉吸声板遇明火火势蔓延的问题。所述矿棉板包括基板和纤维毡，通过粘结剂粘结所述基板和纤维毡，所述纤维毡和粘结剂中包含阻燃剂。
在本申请提供的一种实施方式中，所述粘结剂选自醋酸乙烯酯、聚丙烯酰胺、醋酸乙烯-丙烯酸丁酯共聚乳液和聚乙烯醇中的一种或两种以上。
在本申请提供的一种实施方式中，所述纤维毡选自玻璃纤维毡、玻璃纤维表面毡和玄武岩纤维毡中的任意一种或更多种。
在本申请提供的一种实施方式中，所述粘结剂的用量为150g/m2至300g/m2。
在本申请提供的一种实施方式中，所述纤维毡的厚度为0.3mm至0.5mm、可选地，所述纤维毡的面密度为50g/m2至80g/m2；
在本申请提供的一种实施方式中，所述基板的厚度为12mm至20mm。
在本申请提供的一种实施方式中，所述粘结剂中的阻燃剂选自氢氧化铝、聚磷酸铵、三氧化二锑、三聚磷酸铝、八溴醚、五溴甲苯和氢氧化镁中的一种或多种。
在本申请提供的一种实施方式中，所述粘结剂中阻燃剂的含量为0.25wt.％至1wt.％；可选地，所述阻燃剂的用量为0.4wt.％至0.8wt.％。
在本申请提供的一种实施方式中，所述纤维毡中的阻燃剂选自聚磷酸铵、氯化石蜡、氯化聚乙烯、空心玻璃微珠和磷酸三甲苯酯中的一种或多种。
在本申请提供的一种实施方式中，所述纤维毡中的阻燃剂的含量为3.0g/m2至6.0g/m2。
在本申请提供的一种实施方式中，在所述纤维毡的表面上还可以外加装饰材料或功能性材料，所述装饰材料或所述功能性材料中不包含阻燃剂；
所述纤维毡表面附加的装饰材料或功能性材料的重量为50g/m2至300g/m2；所述装饰材料或功能性材料的厚度为0.05mm至0.3mm；
在本申请提供的一种实施方式中，所述外加装饰材料或功能性材料的方法包括涂覆或喷涂光触媒纳米涂料、喷砂和覆膜中的一种或多种。
本申请的有益效果包括：
虽然普通喷砂覆膜使用的材料可能是可燃材料，不具备阻燃性能，但是该材料应用在本申请提供的矿棉板后，即使普通喷砂覆膜材料燃烧，也不会使得火势蔓延。
本申请的具有高防火性能的覆膜喷砂矿棉板使用主体为聚磷酸铵的阻燃剂添加到纤维薄毡中的有利方面在于：使得薄毡具有阻燃性能，燃烧时无明火并且无蔓延趋势。
本申请通过选择合适的粘合剂，并选择合适的阻燃剂分别添加到粘合剂和纤维薄毡中并优化量的配比，提高了覆膜喷砂矿棉板的防火性能。
