Description
技术领域
建筑领域，流水线生产复合保温板。
背景技术
受亲睐的外墙保温粘锚体系，随着城市越来越高、越来越密，变的也越来越不适用。每当风、霜、雨、雪天气到来，与城市建筑关联的设计、施工、使用者便会忧心忡忡，担心保温层脱落，会产生严重的后果。因此，粘锚体系的建筑保温层已经不能适应现代城市建筑需要。墙体内置保温板、墙体免拆保温模板等，新的建筑保温体系开始得到广泛应用。新的体系必然派生出新的保温层材料要求，以前长期使用的建筑保温层材料，如聚苯乙烯发泡板EPS、聚苯乙烯挤塑泡沫板XPS、石墨阻燃聚苯乙烯泡沫板SEPS以及聚氨酯硬质泡沫板、岩棉板等保温裸板已经不能满足使用要求。新体系对保温层要求不仅要有好的保温效果，同时还要能抵抗现浇混凝土的冲击，不漏浆、能生根，与现浇混凝土粘接成整体。因此，简单的保温裸板已经不能适应新体系的要求，保温板必须升级成能生根、抗冲击、不漏浆的保温板方能使用，同时这种新的保温板还必须考虑运输、装卸、安装的便捷与低成本。
发明内容
保温裸板都是定尺的规格产品，但应用中尺寸总是千差万别。通常是用大尺寸产品，施工现场切割。这种做法不仅浪费而且污染环境。用聚氨酯硬质泡沫包边或粘接得到合适的保温板尺寸，是本公司的独门绝技，经常受到甲方和设计单位的点赞。聚氨酯硬质泡沫成型完美，强度和韧性都很好，尤其是聚氨酯硬质泡沫有很好的粘接强度，可以复合其他各种保温板材，如聚苯乙烯发泡板EPS、聚苯乙烯挤塑泡沫板XPS、石墨阻燃聚苯乙烯发泡板SEPS以及岩棉板、酚醛板、SG防火保温板等。因此，用聚氨酯包边同时形成公母槽结构，是解决大模内置，内置保温板体系，现浇混凝土施工跑浆的好方法。我们改进了聚氨酯板压发泡流水线，增加了两条侧链带，侧链带与上下主链带保持线速度同步，侧链带由高分子材料制备，形状是可插接的公母槽结构，改流动喷料口为固定喷料口，将一个喷料口增加为两个，喷料口安装在发泡流水线入口处，在原料保温板居中，两侧链带与原料保温板边缘之间位置。经改装和试车，实现了有聚氨酯公母槽的复合保温大板。不仅如此，而且可以采用有机与无机两种以上的保温板组合，即降低了成本，又集成了防火隔离带。看似完美，但在施工现场却遇到了麻烦，这种聚氨酯公母槽结构的复合保温大板无法使用，原因是，两层皮。因为，复合保温大板无法生根，于是也就不能和混凝土墙体实现整体浇注，成为一体。于是两层皮的严重问题出现了。解决这一问题的通常做法是李德板，即，两层钢板网，用斜插入保温层的钢条焊接成整体。但，这种通用做法有两个弊端。其一是与运输成本高而且装卸困难。其二是混凝土灌浆无法保证质量，墙体空间有限，而钢板网过于密集。看来问题一个接一个，左右都不是。研发人员经过无数次的实验，最后，找到了解决方法。在原料保温板两面，对称安装90°折边的C型钢条，将C型钢的折边压入保温层中，在复合保温板成型时，两边翻出的聚氨酯包覆在原料保温板两端，盖住C型钢两头，C型钢结实牢固的复合在保温板上，至此，两层皮、保温板无法生根的难题彻底解决。施工现场一个通丝，对穿于对称安装的两面的C型钢间，用螺丝上紧，穿出的通丝作为生根被混凝土紧紧的裹覆，通丝植入混凝土中。于是，两层皮的问题，彻底解决。C型钢条不仅解决了生根的问题，而且是对复合保温层强度的增强。聚氨酯公母槽包边，C型钢增强的复合保温板在流水线上，源源不断的制造出来。
进一步，一种复合保温板流水制备方法，由①在原料保温板的上下两面，对称压入与原料保温板等长度的C型钢，②压入C型钢的原料保温板入4链带板压发泡流水线，③打开4链带板压发泡流水线入口两侧的聚氨酯发泡料喷口，连续喷料，④发泡流水线出口连续产出复合保温板，连续板材经追锯定尺切割，⑤切割成型的复合保温板经包装成成品。所述，原料保温板是EPS苯板、XPS挤塑板、岩棉板、酚醛板、SG防火保温板的一种或两种以上的组合。所述，C型钢是两边都折有90°直边的钢带，所述压入安装是将C型钢的折边嵌入原料保温板中。所述，4链带板压发泡流水线是带有侧链带的板压发泡流水线，并且侧链带是公母槽的结构。发泡温度≤100℃。所述，流水线入口两侧是，原料保温板居中，两侧链带与原料保温板边缘之间位置。每喷口入流量120g～560g(m/min)。所述，切割是追锯切割，所述包装是薄膜包装。
