Abstract
The invention aims to overcome the technical shortcomings of the existing door core corrosion steel plate of a steel fireproof door, and provides an environment-friendly pearlite fireproof door core plate made from a gluing system of an anti-halide accumulation and non-corrosion steel plate. In the invention, a water-soluble silicate binder, a water-soluble silicate curing system, a waterproof auxiliary and reinforced and toughened fiber are mixed with pearlite and pressed to form a pearlite fireproof plate; and the plate not only meets the related requirements on the safety, environmental protection, fireproof and waterproof performance and the like of a fireproof door core plate, but also can achieve the aim of preventing halide accumulation and corrosion of the steel plate.
Description
[technical field]
The invention belongs to a kind of labeled door production environment-friendly type perlite fireproof door core board that use, that do not corrode the labeled door steel plate that is applicable to, meet of the requirement of GB12955-2008 labeled door country new standard the labeled door packing material.
[technical background]
The employed binder system of present most of perlite fireproof door core board is the magnesia cement system; This system belongs to a kind of metastable state system; Time length will make door panel produce anti-halogen phenomenon and then corrosion fire resistance steel door panel, and this is the consistent defective of ordering to fire resistance steel door.Therefore at present a lot of fire resistance steel door manufacturing enterprises have received serious loss.
The objective of the invention is to overcome the deficiency that existing door core corrosion steel plate exists on technology; The environment-friendly type perlite fireproof door core board of the gluing system making of a kind of not anti-halogen, non-corrosive steel plate is provided; It had both satisfied the Essential Performance Requirements of anti-fire door core board material, can reach the purpose of not anti-halogen, non-corrosive steel plate again.
[content of the present invention]
Perlite fireproof door core board described in the invention and the described perlite fireproof door core board of other patents are different; Mainly show on the used cementing agent of perlite fireproof door core board; Develop the environment-friendly type perlite fireproof door core board material of a kind of halogenation, non-corrosive steel plate; Wherein cementing agent has played conclusive effect in this process, and curing system plays a key effect.
Adopt water-soluble silicate as cementing agent, its advantage is the characteristics that it has high temperature tolerance, high-adhesion, hardening time weak point, halogenation, non-corrosive steel plate, and the while has environmental protection, inexpensive, the advantage that is easy to get again.
The curing system of selecting for use comprises silicofluoride, condensed phosphate, inorganic acid, metal, metal oxide, soluble metallic salt and organic compound etc.Wherein silicofluoride is strict in adding use controls addition, and I haven't seen you for ages occurs being difficult to solidifying and meeting water-soluble phenomenon because addition is crossed, and adds to be prone to cause the pollution to environment at most.Add condensed phosphate, the proton that its hydrolysis discharges makes the water-soluble silicate gelation, generates silica sol and promotes to solidify.Adding inorganic acid provides hydrogen ion, guarantees the curing to water-soluble silicate.Adding metal, metal oxide and soluble metallic salt can react except that generating silica sol with water-soluble silicate, also generates a kind of water-fast white gelatinous precipitate, can play good curing waterproof action to water-soluble silicate.Organic compound (comprising organic lipid) hydrolyzable in water-soluble silicate discharges a kind of weak acid, impels the further gel of water-soluble silicate, and the water resistance of the water-soluble silicate after the gel is largely increased.
Add the waterproof auxiliary agent and comprise atoleine, silicone oil and some other silicone based waterproof auxiliary agent, make pearlite slab after curing, reach the excellent waterproof effect, promptly in water, soak and do not loose in 24 hours, water absorption is lower than 5%.
Add and strengthen compressive strength and the rupture strength that toughened fiber improves pearlite slab, comprise some short fibers, like alumina fibre, silicon oxide fibre etc.
Utilize agitator; Mixed liquor with perlite bulk cargo particle (80%-95%) and water-soluble silicate (70%-95%), water-soluble silicate curing system (0.5%-1.5%), waterproof auxiliary agent (0.5%-10%) and enhancing toughened fiber (1%-10%) etc. in stirred tank evenly stirs (being mass percent); Be pressed into the square sheet material of 50cm * 60cm * 4.8cm, compression ratio is 2: 1.
[specific embodiment]
(mass percent)
At present requiring the compressive strength of perlite fire-proof board in the labeled door production is 0.8MPa, and rupture strength is 8MPa, and 24h soaks water absorption rate less than 7%, and anti-combustion temperature is greater than 1000 degree etc.Therefore see preferred the 4th, the 5th assembly side through above data.
[this patent effect]
Result of implementation shows that the perlite fireproof door core by this prescription is made when satisfying compressive strength, rupture strength, coefficient of thermal conductivity, anti-combustion temperature, fire endurance, anti-immersion property, can not produce corrosion to steel plate.Meet the production of fire prevention every core material under the new national standard fully.
