Problems solved by technology

In addition, the new national GB12955-2008 fire door standard has higher requirements for fire resistance temperature and fire resistance time (Class A fire resistance time: 1.5h, Class B fire resistance time: 1.0h), the existing fire door leaf is lower than the new national standard, so , need to find another way

Abstract

The invention discloses a fireproof door leaf, comprising a bottom layer, a surface layer, an intermediate layer arranged between the bottom layer and the surface layer as well as an edge sealing frame which is arranged around the intermediate layer and is arranged between the bottom layer and the surface layer. The fireproof door leaf is characterized in that the intermediate layer is composed of grids and fireproof material filled in the grids, the fireproof material is formed by mixing 40-75wt% of quartzitic sandstone particles, 13-40wt% of magnesium chloride solution, 10-40wt% of magnesium oxide and 1-3wt% of modifier, wherein the percentage concentration by weight of the magnesium chloride solution is 22-30%. The invention has the advantages of realizing simple structure, easy production, long fire resistance time, high fire resistance temperature, low production cost, strong stress endurance and stable quality, completely reaching and even exceeding the requirements of GB12955-2008 fireproof door new standard and achieving fire resistance time of 3 hours.

Description

technical field [0001] The invention relates to a building fireproof component, in particular to a fireproof door leaf. technical background [0002] At present, the existing fire door leaves are basically using perlite series products as the core material of the fire door leaves. Expanded perlite is a non-toxic, odorless, non-combustible, non-corrosive, acid and alkali resistant, heat-preserving, sound-insulating and heat-insulating product with a honeycomb structure inside. This product is mainly used for heat preservation and heat insulation of building roofs and walls ; lightweight aggregate of building materials; various industrial equipment, pipeline insulation layer; the inner wall of various cryogenic and cold storage projects; agricultural and horticultural soilless cultivation, improved soil, water and fertilizer, etc. Chemical industry, electric power, construction, metallurgy and other industries. The operating temperature is -256-800°C, the thermal conductivit...
