目前市场上有哪些A级防火保温材料

目前市场上有哪些A级防火保温材料 提要:目前用于外保温系统的不燃保温材料主要有发泡陶瓷保温板、复合水泥发泡保温板、加气混凝土板、岩棉板(条)等4类。(2)屋面:可做倒置式保温屋面，发泡陶瓷保温板平铺在防水层之上的找平砂浆层上，发泡陶瓷保温板上做水泥砂浆保护层即可。 一、外保温系统不燃保温材料分类 目前用于外保温系统的不燃保温材料主要有发泡陶瓷保温板、复合水泥发泡保温板、加气混凝土板、岩棉板(条)等4类。 1、发泡陶瓷保温板 由无机陶瓷材料经高温焙烧制得的发泡陶瓷保温板材，简称陶瓷保温板。 2、复合水泥发泡保温板 以水泥、粉煤灰、硅灰等为主要材料，经发泡、养护、切割加工等工艺制成的闭孔轻质憎水保温板。 3、加气混凝土板 以轻质材料、硅质材料和发气剂等原料，经一定生产工艺压蒸而成的轻质混凝土板材。 4、岩棉板 以天然火成岩等为主要原料，经高温熔融，用离心法等制成的棉以热固型树脂为粘结剂生产的板材。 二、各种不燃保温材料的特点和系统做法 1、发泡陶瓷保温板 是采用陶瓷陶土尾矿、陶瓷碎片、掺加料等作为主要原料，经1100?左右的高温焙烧，自然熔融发泡形成高气孔率的均匀闭孔陶瓷材料。具有热传导率低、不燃、防火、与水泥砂浆及混凝土等相容性好、吸水率低、热胀冷缩下不变形、不收缩等优点。 Million.
