Lightweight fireproof filling material for metal door produced by expansion perlite and preparation method thereof

Abstract

The invention discloses a lightening fireproof filling material for producing metal door by expanded perlite and a process for preparation. The material comprises expanded perlite, magnesium oxide, magnesium sulfate, calcium hydroxide, aqueous adhesive and water proofing agent, the volume weight is between 200-300kg / m3, the proportionings of each component according to weight percentage respectively are that the expanded perlite takes 45-65, the magnesium oxide takes 15-25, the magnesium sulfate takes 5-15, the calcium hydroxide takes 0.5-4 and the aqueous adhesive takes 2-5. Employing the technical scheme, the product has the advantages of high mechanical strength, light weight, high grade of fire resistance, good effect of sound absorption and acoustic insulation, strong anti-weatherability, heat insulation, heat preservation and energy conservation, easy production and no poison, on hazard and no radiation and the like. The product can be widely used in metal door industry, architectural materials industry and the related industries.

Description

technical field [0001] The invention relates to a lightweight material, in particular to a lightweight fireproof filler which can be used in industries such as antitheft doors, fireproof doors, steel entrance doors and other metal doors, building materials and other industries. Background technique [0002] At present, metal doors such as anti-theft doors, fire doors, and steel entrance doors generally use honeycomb paper and calcium silicate board sandwiched with aluminum silicate cotton as filling materials. The shortcomings of honeycomb paper are: it will burn in case of fire, has no fireproof performance, has poor sound absorption and heat insulation performance, is easy to be affected by moisture, will soften in case of water, and has poor waterproof and water resistance. The disadvantages of calcium silicate board sandwiched with aluminum silicate wool are: low fire resistance level, melting at high temperature, no fire prevention effect, high production cost, asbestos...

AI Technical Summary

Problems solved by technology

The disadvantages of honeycomb paper are: it will burn in case of fire, has no fireproof performance, poor sound absorption and heat insulation performance, is easy to be affected by moisture, will soften when it meets water, and has poor waterproof and water resistance performance.

The disadvantages of calcium silicate board sandwiched with aluminum silicate wool are: low fire resistance level, melting at high temperature, no fire prevention effect, high production cost, asbestos irritation, and great damage to human body by dust inhalation. The State Environmental Protection Administration clearly stipulated in 2005 that household products must not contain asbestos, and adhesives must not contain harmful substances such as formaldehyde and benzene

[0003] The building materials currently used are generally clay bricks and cement products, which have the disadvantages of heavy weight, low strength, poor sound insulation, heat insulation and fire prevention; although relevant scientific research institutions, manufacturers and people of insight have conducted research on the above problems For example, the State Intellectual Property Office authorized and announced on August 24, 2005 a light-weight sound-insulating, heat-insulating, and fire-resistant building material and its manufacturing method. Its patent number is 021084467. Catalysis, to produce inorganic light particles, using inorganic light particles and unsaturated polyester to stir and mix each other, and then molding, so that the unsaturated polyester can be glued and consolidated to make various boards Light-weight sound-insulation, heat-insulation and fire-proof building materials such as strips, bars and columns; its disadvantage is that the production process is complicated and the cost is high, so it is difficult to popularize and apply in the market

[0004] For this reason, many scientific research institutions, manufacturers and people of insight have carried out development and research on the above-mentioned problems, but there is no better improvement method so far.
