Description

一种绿色环保阻燃型双层管道
技术领域
本发明涉及环保材料技术领域，尤其涉及一种绿色环保阻燃型双层管道。
背景技术
管道是用管子、管子联接件和阀门等联接成的用于输送气体、液体或带固体颗粒的流体的装置。通常，流体经鼓风机、压缩机、泵和锅炉等增压后，从管道的高压处流向低压处，也可利用流体自身的压力或重力输送。管道的用途很广泛，主要用在给水、排水、供热、供煤气、长距离输送石油和天然气、农业灌溉、水力工程和各种工业装置中。
现有技术的管道的材质多为铁或者塑料件，其阻燃效果较差，一旦受到火灾，管道容易被烧毁。另外，目前常用的管道为单层结构，若其局部损伤，只能进行整体更换。
发明内容
本发明针对现有技术的不足，提供阻燃效果好、可拆卸的绿色环保阻燃型双层管道。
本发明通过以下技术手段实现解决上述技术问题的：一种绿色环保阻燃型双层管道，包括内层管道、外层管道，所述内层管道同轴内置于所述外层管道的腔体中；所述外层管道的外壁上涂覆有阻燃涂料层；所述阻燃涂料包括以下质量份数的原料制备而成：水性聚氨酯20～35份、水性丙烯酸树脂乳液17～42份、硅酸钠3～6份、聚磷酸铵2～4份、琥珀磺酸盐2～4份、硅烷类消泡剂0.5～2份、去离子水70～90份；所述外层管道的端部开设有卡槽，所述内层管道的端部设置有与所述卡槽相配合的凸起。
优选地，所述内层管道的厚度为1～5cm，所述外层管道的厚度为3～8mm。
优选地，所述阻燃涂料层的厚度为1～3mm。
优选地，所述内层管道的外壁上设置有条形楞，所述外层管道的内壁上开设有与所述条形楞配合的条形槽体。
优选地，所述条形楞、条形槽体的数量相同，每条形楞均沿着对应管道的轴向延伸。
优选地，若干根条形楞、若干条条形槽体分别绕成第一环形结构、第二环形结构。
本发明的优点在于：本发明通过在外层管道的外壁上涂覆本发明的阻燃涂料层，减少管道受热发生损伤的几率；本发明的阻燃涂料采用亲水性的水性树脂作为主体材料，避免了采用DMF、丙酮等危害人体健康的油性溶剂的使用；采用硅、磷阻燃剂复配代替卤素阻燃剂，安全无害；本发明采用双层可拆卸的结构，能方便进行局部维修、更换，也能针对不同的阻燃要求，选择不同的外层管道。
