Floating bead anti-fire door core board

Abstract

The invention relates to a floating bead fireproof door core plate, which is manufactured by the following raw materials according to weight proportion: 30-50 parts of fly ash, 20-30 parts of carbon powder, 10-20 parts of floating beads, 5-12 parts of magnesium chloride, 4-8 parts of polyester rubber, 2-4 parts of alum, 1-2 parts of potassium permanganate and 1-2 parts of ferrous sulfate. The floating bead fireproof door core plate has the advantages of proper weight, low price, and high fireproof and heat insulating performance. In addition, the core plate is inorganic, non-combustible, harmless and innocuous, which meets the technical requirements of the hot-pressing technology, meets the requirements of door core plate stock manufacture and can be used for producing fireproof doors andwindows with modern assembly line work, thus ensuring the fireproof door to have stable production quality and reliable fire resisting limitation and comply with the standard requirements.

Description

technical field [0001] The invention relates to the technical field of building materials, and relates to a fireproof door core board applied to steel, wood and steel-wood structures. Background technique [0002] With the rapid development of high-rise buildings in my country, various fireproof materials and fire doors such as steel, wood, steel and wood, and composite materials continue to emerge. Most of the existing fireproof materials use expanded perlite, aluminum silicate, ceramic cotton and other fireproof materials, and their prices are relatively high. Due to the fierce competition in the fireproof door market, some companies use low-priced, poor fireproof and fireproof performance in order to profit. Alternative materials, such as rock wool, cause serious quality problems for fire doors. [0003] At present, there are more than 400 enterprises producing fire doors in my country. Most of the inner core fillers of steel, wood and steel-wood structure fire doors pr...

AI Technical Summary

Problems solved by technology

Most of the inner core fillers of steel, wood and steel-wood structure fire doors produced are made of expanded perlite and aluminum silicate ceramic wool, but a considerable number of fire door manufacturers use low-quality, It is difficult to guarantee the appearance quality and fire resistance of fire doors if low-priced rock wool is used as the inner core filler, etc.

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.
