High-flame-retardant steel fireproof door made of environment-friendly filling material

Abstract

The invention discloses a high-flame-retardant steel fireproof door made of an environment-friendly filling material, and relates to the technical field of fireproof doors. The high-flame-retardant steel fireproof door comprises a fireproof door housing, wherein a storage box containing cavity is formed in the fireproof door housing; three lower sliding grooves are formed in the bottom end face ofthe inner wall of the storage box containing cavity; three upper sliding grooves are formed in the top end face of the inner wall of the storage box containing cavity; a T-shaped limiting groove is formed in the upper part of the storage box containing cavity; two limiting holes are formed in the inner wall of the T-shaped limiting groove; a distilled water storage box, a dry powder storage box and a yellow sand storage box are sequentially connected into the storage box containing cavity in a sliding mode from back to front; a T-shaped sliding block is connected into the T-shaped limiting groove in a sliding mode; and the distilled water storage box, the dry powder storage box and the yellow sand storage box are limited through the T-shaped sliding block. According to the high-flame-retardant steel fireproof door, the yellow sand storage box, the dry powder storage box and the distilled water storage box are combined for use, a fire can be extinguished step by step, and the fire is prevented from further spreading.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a steel fire door. Background technique [0002] The accredited laboratory designated by the Ministry of Fire and Economic Affairs, according to the new national standard for fire doors GB_12955-2008 implemented on January 1, 2009, has passed the fire door fire resistance test method, and has obtained the verification registration certificate and authorization issued by the Standard Inspection Bureau of the Ministry of Economic Affairs The identifier is called a fire door. [0003] At present, there are many kinds of fireproof materials used for doors on the market, with different fireproof performance. However, there are very few doors made of high-strength, environmentally friendly fireproof materials. For example, the steel fire door fillers currently used are mostly silicic acid fiber, rock wool sticky, etc. Their disadvantages are low strength, toxicity, great harm to t...
