SG石膏基钢结构防火涂料
摘要：
本发明涉及防火涂料，特别适用于钢结构材料外表面防火涂层。属于消防材料技术领域。采用改性半水石膏为粘结剂，膨胀蛭石，珍珠岩，云母，特制添加剂(WH)，复合改性剂(FH)，轻质碳酸钙，按重量450-430∶115-130∶160-140∶30-40∶3-5∶8-12组成，且上述物料按序放入搅拌器搅拌20秒。本发明具有涂层不收缩，强度增长快，防火性能和抗裂性都有明显改善等优点。
摘要（英）：

The invention relates to a fire-retardant coating, in particular to a fire-retardant coating applicable to the outer surface of a steel structure material, and belongs to the technical field of fire-fighting materials. Modified semihydrated gypsum is used as an adhesive. The fire-retardant coating consists of expanded vermiculite, pearlite, mica, a special additive (WH), a composite modifier (FH) and light calcium carbonate in a weight ratio of (450-430):(115-130):(160-140):(30-40):(3-5):(8-12). A preparation method comprises the following steps of: sequentially putting the materials into a stirrer, and stirring for 20 seconds. The fire-retardant coating has the advantages that: the coating is not shrunk, the strength is increased quickly, and the fireproof performance and crack resistance are remarkably improved.
