Description

一种保温结构一体化的复合免拆模板及其制备方法
技术领域
本发明涉及建筑保温材料技术领域，具体为一种保温结构一体化的复合免拆模板。
背景技术
外墙免拆模板及保温一体化，是一种新型建筑节能与结构一体化技术，它以水泥基双面层复合保温板作为永久性外模板，内侧浇筑混凝土，外侧抹抗裂砂浆保护层，通过连接件将双面层复合保温板与建筑结构牢固连接在一起，结构与保温同步施工，减少了施工工序和模板用量，缩短了施工工期，降低了施工成本，质量安全可靠，能够与建筑物同寿命。
目前，用于保温结构一体化的免拆模板大多是在挤塑板的两侧分别复合砂浆保护层，需要经过两次养护，为达到防火要求，挤塑板的外侧砂浆保护层厚度通常要在45mm以上，并要由粘接层、防火构造层、保护层等多层结构组成，生产效率较低，养护设备投入大，占用大量的厂房场地，而且外侧的保护层重量大，存在分层、脱落等安全隐患。
发明内容
针对现在技术的不足，本发明目的是提供一种强度高、防火性能好又具有优异热工性能的保温结构一体化的复合免拆模板及其制备方法，流水线生产，缩减了厂房场地用量，减少了设备投入，大大提高了生产效率。
本发明是采用下述技术方案实现的：

进一步，所述的模压无机胶苯颗粒保温板按以下步骤制备：a、将经过界面剂处理的聚苯乙烯颗粒与无机阻燃浆料混合、搅拌制成胶苯颗粒浆料，聚苯乙烯颗粒与无机阻燃浆料的重量比为1/6～9；b、将胶苯颗粒浆料注入模箱中，采用压力机压缩后锁紧模箱的上盖板；c、将模箱放置在养护室内，胶苯颗粒浆料保压养护4-6小时后脱模，再自然养护制成胶苯颗粒胚体；d、按要求规格对胶苯颗粒胚体进行切割制成模压无机胶苯颗粒保温板。模压无机胶苯颗粒保温板强度高(抗拉强度≥0.15MPa\抗压强度≥0.45MPa\抗折强度≥0.55MPa)、阻燃效果好(防火等级A2)、保温性能优异(导热系数≤0.05W/m.k)，还具有良好的韧性，在压力机作用下不破坏其物理性能。
进一步，所述的A级保温板厚度为35mm～45mm。
进一步，所述的A级保温板为一块或多块，当所述的A级保温板为多块时，板缝宽度为10mm～20mm，板缝内填充聚合物保温砂浆形成加强肋，还将多块A级保温板粘结成一体。

4、将钢丝网和水泥基布分别置于开卷机上，与传输机上的保温板同步进入双履带层压机，所述的双履带层压机链板设有加温装置，在双履带层压机运行过程中完成粘结剂(微发泡聚氨酯组合料)的发泡成型与熟化，将A级保温板、B级保温板、钢丝网和水泥基布粘结为一体；
5、经过切割机、翻板机，物料继续传输到砂浆铺装线，在A级保温板上面铺设内置玻纤网格布的聚合物砂浆后进入养护室养护；
6、养护完成后经过切割，制成保温结构一体化的复合免拆模板。
本发明的有益效果：本发明提供一种保温结构一体化的复合免拆模板及其制备方法，强度高、防火性能好、热工性能优异，流水化生产，减少了设备投入，降低了生产成本，缩减了厂房场地用量，生产效率高，市场优势明显。
