一种耐高温耐腐蚀的钢质防火门
摘要：
本实用新型涉及一种防火门，尤其涉及一种耐高温耐腐蚀的钢质防火门。属于防火门制造技术领域。一种耐高温耐腐蚀的钢质防火门，包括门框和门扇，所述门框和门扇通过防火铰链连接，所述门扇釆用冷轧钢板做面板，所述门扇内填充有改性膨胀珍珠岩。本实用新型把膨胀珍珠岩放在反应前驱液中，然后在一定条件下是使反应前驱液生成树脂，使得所述膨胀珍珠岩成为被该树脂完全浸润的膨胀珍珠岩，赋予了该珍珠岩的树脂特性，不仅使得该珍珠岩更耐火耐腐蚀，并且使得该珍珠岩在高温下的抗冲击性能得到增强、粉化率显著降低。因此，用该膨胀珍珠岩制成的防护门芯层具有良好的防护性能。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model relates to a fire door especially relates to a high -temperature and corrosion resistance's steel fireproof door. Belong to and prevent that fire door makes technical field. A high -temperature and corrosion resistance's steel fireproof door, includes door frame and door leaf, door frame and door leaf pass through fire safety hinge and connect, the door leaf adopts the cold -rolled steel sheet to make the panel, the door leaf intussuseption is filled with modified expanded perlite. The utility model discloses put expanded perlite in reaction forerunner liquid, then make reaction forerunner liquid generate the resin under certain condition, make expanded perlite becomes the expanded perlite who is soaked completely by this resin, has given the resin characteristic of thispearlite, not only makes this pearlite more fire -resistant corrosion -resistant to make the shock resistance of this pearlite under high temperature obtain the reinforcing, pulverization rate is showing and is reducing. Consequently, the guard gate sandwich layer of, making with this expanded perlite has good barrier propterty.
