Description

一种钢化防火防爆玻璃及其生产工艺
技术领域
本发明涉及防火玻璃设计制造技术领域，特别是涉及一种钢化防火防爆玻璃及其生产工艺。
背景技术
目前，国内外市场上常见的防火玻璃大多为夹层复合防火玻璃和夹丝防火玻璃，前者中加入的防火胶粘剂在紫外线照射下很快就变成乳白色并产生气泡，严重影响玻璃的透光性，使用寿命较短，且采用手工操作与控制，生产效率地下，产品质量难以保证，无法进行大规模工业化生产，而夹丝防火玻璃不仅透光度欠佳且不能阻止热量辐射，还存在着安装笨重等问题，限制了作为建筑物外墙玻璃的使用。此外，还有一种单片防火玻璃，采用喷涂法对普通浮法玻璃进行钢化。
而现有单片防火玻璃的制作，一般只是以普通平板玻璃或钢化玻璃等材料作为原片，在这些半成品制品的基础上，进行抛光、清洗以及防火处理等工艺流程和方法处理，满足防火玻璃的性能要求。其防火玻璃的质量达到国家标准的性能指标，主要表现在尺寸偏差、外观质量、耐火性能、弯曲度、透光度等方面。现有防火玻璃的制作方法主要是将玻璃在高温环境下加热，然后在高压风气流的作用下进行冷却，该制作方法存在许多弊端，主要是强度不高、抗冲击和耐热防火性能差,极大地限制了其使用范围，因此急需一种高强度的防火玻璃。
但是，现有的楼房大多为高层建筑，若发生玻璃碎裂，玻璃碎片会从高层向底面坠落。
发明内容
本发明所要解决的技术问题是，克服现有技术的缺点，提供一种钢化防火防爆玻璃，在玻璃发生碎裂时，减少甚至消除坠落碎片。
为了解决以上技术问题，本发明提供一种钢化防火防爆玻璃，包括至少一个夹胶防爆单元，夹胶防爆单元包括至少两块钢化玻片，相邻钢化玻片之间通过胶黏层粘结相连，相邻夹胶防爆单元之间通过铝格条支撑连接，两夹胶防爆单元与铝格条围成真空隔层。
技术效果：建筑门窗用的玻璃一般都是单片钢化玻璃，如果破裂，碎掉的玻璃颗粒会掉落。本方案中钢化玻片发生爆裂时，玻璃碎片会粘附在胶黏层上，大大减少了玻璃碎块掉落的情况。并且本方案中用钢化玻片构成夹胶玻璃，再用夹角玻璃组合成中空玻璃，可以更好的起到节能的作用。
本发明进一步限定的技术方案是：钢化玻片的厚度为2～5mm。
本发明进一步设置为，胶黏层的厚度为0.45～1mm。
本发明进一步设置为，夹胶防爆单元远离铝格条的面上涂有防火液层。
本发明进一步设置为，防火液的组份按照质量份数为，钾水玻璃20-40份、水100份、氰基丙烯酸酯8-10份、二羟基聚二甲基硅氧烷5-7份、十二醇脂3-7份、季戊四醇0.2-0.5份、环氧大豆油1-4份、三氧化二铝12-15份、陶粒11-13份、混合偶联剂0.5-1份、稳定剂2-4份、触变剂0.2-0.4份、增稠剂2-5份、杀菌剂1-2份。
本发明的另一目的在于，提供一种用于制造上述任意方案的钢化防火防爆玻璃用钢化玻片的工艺，包括，
切大片，将玻璃原料切割成适当的大小，得到片状粗坯；
预处理，根据成品钢化玻片的形状、结构，对片状粗坯进行钻孔、划线、掰边、抛光处理；
洗涤干燥，对预处理后的玻片进行清洗并烘干；
高温软化，将烘干的玻璃送入加热炉内加热，炉内温度为580℃～680℃，加热时间根据玻璃厚度不同在60s～180s，玻璃厚度越小，所选用的炉内温度越低；
风栅淬冷，当玻璃厚度为2mm时，玻璃的出炉速度为不低于540mm/s，且玻璃厚度每增加0.5mm，出炉速度降低10mm/s，同时向软化的玻璃上均匀的吹冷风；
急冷阶段，急冷风压在8～24kPa，改变风栅到玻璃之间的距离，可对风压进行微调，根据所生产的钢化玻璃厚度不同，选用不同的急冷风压，玻璃厚度越小，所选用的急冷风压值越大；
冷却阶段，保持冷风温度不变，并减小风压，使冷却风压保持在2kPa；
收集成品，包装入库。
本发明的有益效果是：
(1)本发明的钢化防火玻璃，表面具有防火液层，防火液层不但可以起到防火的作用，还可以起到保护钢化玻璃的作用，外力作用在本发明的防火防爆玻璃上时，先作用在防火液层上，起到一个保护缓冲的作用；
(2)本发明的钢化防火玻璃中具有真空隔层，在楼房门窗上安装时，可以起到良好的隔热节能作用；
(3)本发明中胶黏层不但可以起到防止玻璃碎片掉落的作用，还可以在发生外力撞击时，起到缓冲作用，减小外力继续向钢化防火玻璃内冲击的趋势。
