Nanometer fireproof door

Abstract

The invention discloses a nanometer fireproof door. The nanometer fireproof door comprises a door frame, a fireproof door plank and a door lock, the side edge of the door frame is hinged to the fireproof door plank through hinges, the door lock is arranged on the fireproof door plank, the fireproof door plank comprises an outer layer fireproof plate and an inner layer fireproof plate, a cavity is formed between the outer layer fireproof plate and the inner layer fireproof plate, connecting pieces are arranged in the cavity, one end of each connecting piece is connected with the outer layer fireproof plate, the other end of each connecting piece is connected with the inner layer fireproof plate, a dust absorption layer is arranged on the surface of the inner fireproof plate, a decoration layer is arranged on the surface of the outer layer fireproof plate, and nanometer films are applied to the surface of the dust absorption layer and the surface of the decoration layer respectively. The nanometer fireproof door is simple in structure, through the arrangements of the nanometer films, the inner layer fireproof plate and the outer layer fireproof plate, the fireproof effect can be achieved effectively, in addition, through the arrangement of the dust absorption layer, the dust diffusing in the air can be absorbed effectively, the indoor environment can be improved, the overall weight of the fireproof door is reduced, and meanwhile the structural strength of the fireproof door is not affected.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a nano fire door. Background technique [0002] Nanoscale structured materials are referred to as nanometer materials for short, which means that the size of their structural units ranges from 1 nanometer to 100 nanometers. Since its size is close to the coherence length of electrons, its properties change greatly due to self-organization brought about by strong coherence. Moreover, its scale is close to the wavelength of light, and it has a special effect of a large surface, so its properties, such as melting point, magnetism, optics, thermal conductivity, electrical conductivity, etc., are often different from those of the substance in its bulk state. the nature of the performance. Also because of the different characteristics of nanoscale structure materials, they are used in various industries. [0003] With the country's large-scale infrastructure construction, the dem...

Problems solved by technology

The performance requirements are getting higher and higher, such as the subways under construction in some large and medium-sized cities, the reconstruction and expansion of airports and stadiums, etc. In these important occasions, the requirements for the fire prevention and warning sectors have increased. For this reason, the country has promulgated a new standard GB12955-2008 "Fire Doors", and stipulates that the use of the old standard will be delayed until April 30, 2009. The implementation of the new standard is imperative, and the old standard can no longer meet the existing needs to a certain extent.

Moreover, the existing fire doors generally use fireproof board fireproof materials, and there are still shortcomings such as lack of aesthetic feeling on the outer surface of the fireproof board, poor fireproof effect, etc., and with the increasing environmental pollution, a lot of dust often permeates the air in the house. It also affects people's health, so we propose a nano fire door
