Fireproof inorganic door

Abstract

The present invention discloses making process of fireproof inorganic door core and door leaf. The fireproof inorganic door core and door leaf is made with expended perlite 30 wt%, talcum powder 10 wt%, magnesia 20 wt%, magnesium chloride 20 wt%, urea formaldehyde glue 10 wt%, polyester glue 5 wt%, alum 3 wt%, potassium permanganate 1 wt%, and ferrous sulfate 1 wt%, and through mixing, hot pressing at pressure of 200-400 tons and temperature of 100-350 deg.c for 60-120 min. The fireproof inorganic door core and door leaf has high fireproof and heat isolating performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an inorganic non-combustible fireproof door applied to steel, wood and steel-wood structures. Background technique [0002] With the development of society and the acceleration of urbanization, more and more high-rise buildings have sprung up, and the problem of fire prevention has always been a problem that cannot be ignored for high-rise buildings. Therefore, the research and development of products such as fire doors Production and production have played a positive role in ensuring the safety of people's lives and property. [0003] At present, domestic fire doors are mainly divided into two categories: wooden fire doors and steel fire doors. The basic structure of the fire door is as follows: the door frame is made of flame-retardant wood, the two panels of the door leaf are flame-retardant plywood, the inner sides of the two panels are usually lined with inorgani...

Problems solved by technology

[0004] It can be seen from the above that the inner core filler of the fire door is particularly important for its fireproof effect, but in actual conditions, many fire door manufacturers use aluminum silicate ceramic wool more, but there are quite a number of fire door manufacturers in order to Self-interest, but using low-quality and low-priced rock wool as the inner core filler as fire-proof and heat-insulating materials, it is difficult to guarantee the appearance quality and fire-resistant performance of fire-resistant doors

Furthermore, although aluminum silicate ceramic wool and rock wool are inorganic products, they are all fibrous substances, which are seriously harmful to the human body and the environment, and are not conducive to human health.
