具体实施方式
实施例1
见图1至11，本实施例的绝热保温板100包括：真空绝热板11、包覆该真空绝热板11的至少一个侧面的发泡材料12，或所述发泡材料12整体包覆真空绝热板11。所述发泡材料外侧设有铝膜13，或发泡材料外侧涂覆有金属漆。
所述发泡材料12和铝膜13之间设有无纺布或玻璃纤维层14，铝膜13为镀铝膜或铝箔膜或铝塑膜；或，在发泡材料上包覆无纺布或玻璃纤维布后，涂覆金属漆（优选铝粉漆）。其中，玻璃纤维层的设置，可进一步提高防火性能。
该绝热保温板呈矩形，且至少在一对对称的边缘上设有台阶或斜面。
所述真空绝热板包括：芯材，用于真空封装该芯材的封装铝膜。
如图3或4，在绝热保温板相对的两侧设置台阶，以在铺设地面或墙面时，台阶部可以搭接，并使铺设的地面或墙面的外侧面平整，如图7或8。
或如图5、6，将分别在边缘设有凸棱与条形槽的两块绝热保温板进行对接，并使铺设的地面或墙面的外侧面平整，如图9。
或将绝热保温板制成如图10的凸字形，并与图1或2中的绝热保温板配合，铺设地面或墙面，其中，将相邻两块凸字形的绝热保温板的相邻端部的不具有真空绝热板的部分（即凹槽部），嵌入另一块图1或2中的平面式的绝热保温板进行拼接，并使铺设的地面或墙面的外侧面平整的同时，使得铺设的地板或墙板完全被真空绝热板覆盖，进一步提高加热性能。具体施工时，绝热保温板采用胶水或双面胶带进行固定。铺设的地板上方，可以设置地板或地暖盘管；铺设的墙板外侧面上可以设置墙纸或其他涂层。
实施例2
如图12-15，本实施例的可折叠便携式保温箱1，采用隔热镀铝膜或铝箔膜或铝塑膜材构成的矩形箱体，箱体的顶部具有可掀开的箱盖；箱体内具有由前板、后板、左板、右板、底板构成的容腔；容腔顶端口敞开，箱盖的内侧设有盖板2，箱盖将箱体闭合时，该盖板2适于嵌入所述容腔的顶端口，或盖板2适于整体覆盖所述容腔的顶端口；前板、后板、左板、右板、底板和盖板都包括：绝热芯板（优选真空隔热板、发泡板、包覆有发泡材料的真空隔热板等）。
隔热镀铝膜或铝箔膜或铝塑膜材包括依次叠层设置的：真空镀铝膜或铝箔膜或铝塑膜、PE膜、珍珠棉和PE编织布。该膜材柔性较好且耐冲击，且具有隔热、保温的功能。
底板的前边缘设有拉手带，底板的后边缘通过魔术贴连接在后板的底部；箱盖的前边缘整体向前延伸有延伸部21，该延伸部21通过魔术贴与箱体前侧面顶部相连，实现在箱体闭合时固定箱盖，并提升密封性；箱体左右两侧设有飞边3，各飞边3通过魔术贴与箱盖的顶面相连，以进一步固定箱盖，并提升密封性。
至少是前板、后板、左板、右板、底板和盖板之一的内侧面上设有用于放置蓄冷剂盒的网袋4，该网袋4的开口处设有魔术贴41,用于封闭网袋4的开口，以固定蓄冷剂盒。
若需将保温箱折叠，步骤包括：打开盖板，提起所述底板的拉手带并取出底板，然后将底板、左板、右板平行对齐设置后平行设于前板、后板之间，然后将箱体的前、后壁体向中央挤压，并用设有魔术贴绑带10收紧箱体的前、后壁体，然后将盖板向后折叠在箱体的后壁体上，即完成折叠、定型，如图2。
箱体的外侧面上设有透明袋5，以方便设置标签或快递单等。
邻近箱体左、右壁体的顶部和/或底部的外侧面上设有把手织带6，以便于搬运。
采用耐磨、耐冲击材料（如PC等塑料）制成的护角7，护角由彼此基本垂直的三个面构成，护角通过魔术贴或强力胶水或双面胶粘接于、或缝合于保温箱底部的四个角上。
箱体上设有与箱体的两侧相连的背带。
实施例3
在实施例1的基础上，本实施例存在如下变型：
如图16-18，在箱体底面上邻近各端角处缝制梯形的耐磨布8（优选帆布），并使底板底面上的各端角不被耐磨布覆盖；将耐磨片9（优选硅橡胶插片）的凸台插入耐磨布，耐磨片9整体基本呈三角形的片体，在耐磨片9的端角处设有凸台91；该凸台91设于箱体底面上的各端角处，且不被耐磨布覆盖，起到防撞防摩擦的作用。使用时，若采用一端拎空的方式拖行箱体，由于着地端的耐磨片的凸台起到支点的作用，故而保护了箱体底面不会受磨损。当耐磨片的凸台磨损后，直接更换新的耐磨片，使用便捷，成本低廉。
进一步优选的方案是，凸台底面中央设有安装槽，安装槽内设有金属小圆珠，小圆珠露出安装槽，起到防摩擦、减小阻力的作用。安装槽的槽口呈圆形且直径小于小圆珠的直径。
实施例4
在实施例1的基础上，本实施例存在如下变型：
见图19，本实施例的真空绝热板11的外侧面通过胶水或双面胶粘贴在一装饰板15的内侧面上，且该装饰板15在该真空绝热板11上的投影可完全覆盖该真空绝热板11；发泡材料12发泡成型在该真空绝热板11和装饰板15的内侧面上，并将该真空绝热板11的内侧面和四个端面包覆，进一步，也可同时将装饰板15的四个端面包覆。
装饰板15与发泡材料12的接触面上分布有槽或沉孔16，以使发泡材料12牢固固定在装饰板15上。所述沉孔16优选断面呈梯形（如图20）或带缺口的环形（如图21）或壶形（如图22）的沉孔，该沉孔16的顶端口孔径小于底部的孔径。采用该沉孔，可以使发泡材料12进入沉孔内发泡，使得装饰板15与发泡材料12连接牢固。
装饰板15为金属装饰板、木塑板、PVC板、石膏板等。所述发泡材料外侧设有铝膜13，或发泡材料外侧涂覆有金属漆。
所述发泡材料12和铝膜13之间设有无纺布或玻璃纤维层14。
显然，上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本发明的精神所引伸出的显而易见的变化或变动仍处于本发明的保护范围之中。
