Description
技术领域
本发明涉及建筑墙体外墙外保温隔热材料领域,尤其涉及一种免拆复合保温模板的生产方法。
背景技术
建筑节能是我国长期坚持的基本国策,由于国家强制执行的力度加大,建筑节能材料发展十分迅速,建筑节能已成为全国备受关注的焦点问题,也是我国今后经济建设中的一件大事,传统的外墙保温已不适应当前形势发展的需要,有机外墙外保温板带来的火灾事件、群死、群伤,惨祸不断,触目惊心,无机发泡材料在节能效果和抗冲击强度,吸水率、耐久性还达不到标准要求,这就要求我们在工艺上革新,在技术上创新,尽快加速研制开发新产品,以此推动我国建筑节能健康快速发展。
我国建筑节能与防火安全的现状;由于我国的建筑节能起步晚,和发达国家相比差距大,技术落后,品种少。在保温节能效果方面并不理想,节能效果真正达到65%以上者还不足50%,在工程质量方面存在着不合理的保温层构选,不合理的保温层抹灰,不合格的保温材料设计,不合理的空腔构造,不合理的饰面配套,面层开裂,还存在着墙体耐久性问题;抗风化和大气稳定性问题;防水问题;隔声问题;尤其是施工工艺、施工安装方式,接点构造,质量验收,施工及管理问题,从而造成了外墙外保温层的局部破损、层面开裂,渗水、脱落,耐久性差,保温效果达不到设计要求。
越是保温效果好的产品,防火性能越差。公安部出台规定,今后民用建筑要选用燃烧性能为A级(即不燃材料)的外墙外保温材料,旨在遏制易燃可燃外墙外保温材料引发火宅的势头。
但现实是我国市面上使用的建筑外墙外保温材料主要为:EPS板、XPS板和PU板等有机保温材料。即使加足量的阻燃剂,也不可能达到“A级”。
现有的单一有机保温材料已不能满足市场和使用需求,本申请研发一种有机与无机材料复合保温隔热材料,解决已有保温材料的缺陷、完善建筑节能材料,是非常有必要的。
发明内容
本发明的目的在于提供一种免拆复合保温模板的生产方法,以解决上述技术问题。有机与无机材料相复合的保温隔热材料、以解决已有保温材料的缺陷、更好地更有效的完善建筑节能材料,使千家万户和社会受益,人民和国家财产免遭损失。
首先应解决的技术是免拆保温模板的导热和强度,温差变化对产品的影响,用无机材料怎样去包裹有机材料、解决墙体保温材料的保温隔热、防水防火的性能,并使产品工业化生产中解决实质性的难关,在使用过程应达到震动频率高而不损失的目的。以及整个外墙外保温系统的耐候性,防水防火,不开裂,不空鼓脱落,杜绝外墙外保温工程质量隐患。
本发明所要解决的技术问题采用以下技术方案来实现:
一种免拆复合保温模板的生产方法,其特征在于,步骤如下:
(1)制备粘结砂浆
粘结砂浆由如下重量百分比的原料制成:40%-50%的425#水泥、40%-50%的水洗砂、1%-2%的羟丙甲基纤维素、0.5%-1%的甲基纤维素、13%-15%的可再分散乳胶粉,以上各原料百分比之和满足100%;
上述各原料加适量水搅拌5min以上,制成湿浆料即得粘结砂浆;
(2)粘结砂浆送到底层已铺设好第一层网格布的成型机中滚压、刮平,粘结砂浆在第一层网格布上铺设厚度为3-5mm;
(3)在刮平的粘结砂浆上铺设挤塑板,挤塑板中间开孔以增加抗压强度和抗拉强度;
(4)在挤塑板上再铺设一层3-5mm厚的粘结砂浆,在该粘结砂浆上铺设第二层网格布;
(5)在第二层网格布上设置3-5mm厚的抹面胶浆,在抹面胶浆上铺设第三层网格布,滚压网格布使网格布的网孔内充满浆料;
(6)自然固化后进行切割,即可。
所述抹面胶浆如下重量百分比的原料制成:40%-50%的425#水泥、40%-50%的水洗砂、1%-2%的羟丙甲基纤维素、0.5%-1%的甲基纤维素、8%-12%的可再分散乳胶粉、2%-4%的长纤维、1%-2%的保温粉,以上各原料百分比之和满足100%。
所述网格布为加强耐碱网格布。
本发明的有益效果是:
本发明的产品利用无机胶凝材料包裹有机材料EPS颗粒,将它们有机地结合起来,达到保温模板的导热系数低、隔热性能好,更能达到防水、防火的功能;既解决了原有保温材料的火灾隐患,又达到不渗水、开裂、空鼓脱落。
本产品的特性既达到建筑节能要求,又针对现有技术不足而研发的防水防火,杜绝外墙外保温系统工程质量隐患,并可广泛应用在框架结构的梁柱、剪力墙,楼板或层面与砼同时施工,与墙体同寿命,既解决了热桥部位保温隔热又代替模板,降低了工程的综合经济造价。
