Description
Technical field
The present invention relates to field of material technology, and in particular to a kind of novel flame redundant material is more particularly to one kind and can be used for
The fire proofing of indoor decoration board.
Background technology
Requirement of the building board in the prior art for fire protection flame retarding is higher and higher, has developed multiple types
The flame-proof sheet material of type, as by plank add fire retardant by reach flame retardant effect, or directly using fire proofing come
Prepare building board.But there is also shortcomings for plank in the prior art, for example, these planks only have fireproofing passiveness work
With burning of the flame to plank itself can only be prevented.And the upgrading for not having flame retardant property plank to having installed,
It is only capable of realizing by removing and creating flame-proof sheet material.
Therefore, it is necessary to develop it is a kind of have reinforce flame retardant effect while can be used for upgrading existing plank flame retardant property
Fire proofing.
Invention content
The present invention provides a kind of novel flame redundant material, by the way that metal mesh, the graphite of quick conductive, acceleration pair are arranged on surface layer
The release of internal ignition resistant material, while adhesive phase is set in bottom, it can easily be attached directly to existing non-flame resistant plate
On material, to realize the technique effect reinforced flame retardant effect while can be used for upgrading existing plank flame retardant property.
To realize above-mentioned goal of the invention, the technical solution adopted by the present invention is as follows：A kind of novel flame redundant material, including thickness
Degree is the graphite tabletting of 1-3mm, and graphite tabletting upper layer is provided with is made metal mesh, the heat conduction by heat conduction fuse metal silk
A diameter of 0.1-1mm in fuse metal silk；The lower layer of the graphite tabletting is provided with composite flame-proof oxidant layer, the composite flame-proof
Oxidant layer thickness is 5-10mm；The lower layer of the composite flame-proof oxidant layer is provided with fire prevention bottom；Lower layer's setting of the fire prevention bottom
There is adhesive phase, several self threading pins for being used to connect with fire prevention bottom are additionally provided on the metal mesh；On the self threading pin
It is cased with gasket.Self threading pin and gasket are used to reinforce the supporting role of metal mesh, especially when the fire proofing of the present invention is set to top
When portion's wall, the deficiency of heat conduction fuse metal silk intensity can be effectively made up.
In yet other embodiments, the metal mesh be arranged to it is cellular, the six of the cellular formation
The length of side of side shape is 1-3cm.Cellular construction can save material, while also beautiful and generous.
In yet other embodiments, the fire prevention bottom be selected from hard polyurethane foams, lightweight aluminium sheet or
One kind in iron plate.Preferably mixed with the hard polyurethane foams of fire retardant, hard polyurethane foams have hard polyurethane foams
Higher anti-flammability and lower smokiness, therefore there is higher security performance.Bottom of preventing fires can also be selected from traditional light
The shortcomings that matter aluminium sheet or iron plate, metal material plank is heavier-weight, can influence the portability of fire proofing of the present invention.This hair
Bottom of most preferably preventing fires in bright is selected from hard polyurethane foams.The thickness of the hard polyurethane foams is 5-15mm.
In yet other embodiments, the composite flame-proof oxidant layer contains, and is uniformly mixed as mass fraction
Following powder：60-70% potassium nitrate, 3-5% basic magnesium carbonates, 2-4% potassium hyperchlorates, 10-25% phenolic resin, 5-10%
Nitrocellulose, 0.1-1% stearate.The composite flame-retardant agent can fire-retardant main function be decompose heat absorption and to combustion
Burn the inhibition of active group.It is believed that fire retardant is after heated, it may occur that decomposition reaction, decomposition reaction can absorb a large amount of heat, lead
The temperature of burning things which may cause a fire disaster is caused to reduce；The heated potassium dissociateed can inhibit the disseminator in burning chain reaction, such as O, H, OH
Equal free radicals, free potassium can recombinate to form more stable molecule with these active groups：Potassium oxide, potassium hydroxide etc., most
Fire-retardant effect is played eventually.Graphite flake also plays prior effect other than it can speed up heat conduction.When fire retardant starts
Afterwards, it decomposes generation or newly-generated potassium oxide can further react under the high temperature conditions with graphite, generate potassium and an oxygen
Change carbon, above-mentioned reaction is strong endothermic reaction, and the potassium generated can continue extinction free radical, and it is double with chemistry to reach material
Fire extinguishing acts on again.
Further, the grain size of the powder is 1-20 μm.When the grain size of powder is excessive, it can reduce and shed, adsorb work
With and so that flame retardant effect is reduced.
In yet other embodiments, the heat conduction fuse metal silk is selected from mock silver or tin bronze alloys
Manufactured wire.The primary and foremost purpose that heat conduction fuse metal silk is chosen is that have preferable heat conductivility, and have lower
Fusing point, suitable heat conduction fuse metal can be mock silver or tin bronze, and above-mentioned material heat conduction is good, fusing point is low.With conventional pilot
Thermometal such as copper is compared, although thermal conductivity not as good as copper, due to low-melting reason, can start to decompose in fire retardant or
Starting stage, that is, the fusible for starting loss, causes composite flame-proof oxidant layer to lose support, fire retardant all comes down in torrents to mistake rapidly
Fiery space reaches flame retardant effect with most fast speed.
In yet other embodiments, the fire prevention bottom is provided with corresponding with the metal mesh shape
Grid, forms accommodating chamber between the grid, and the accommodating chamber is used to accommodate the powder in composite flame-proof oxidant layer.By composite flame-proof
Oxidant layer is separated into small space, prevents powder from assembling to side when being readily transported, installing, composite flame-retardant agent is enable to be uniformly distributed.
The invention has the advantages that：
(1), the present invention uses heat conduction fuse metal silk and the dual heat conduction of graphite tabletting, the heat transfer of burning things which may cause a fire disaster to wire
After, high temperature can be transferred in whole network rapidly by wire, and graphite has layer structure, and heat-conducting effect is very in the horizontal direction
It is good, after heat transfer to graphite, heat can be transferred to rapidly entire plate of material, start the work of fire proofing with most fast speed
Make.
(2), fire retardant of the invention is powdered, has certain fugacity, compared to other flame-proof sheet materials, this hair
Bright fire retardant can be spilt into entire space, not only act as fire retardation, can also play the role of extinguishing burning things which may cause a fire disaster.
(3), graphite tabletting of the invention is ingenious in design, plays the role of heat conduction and participates in reaction dual.
(4), fire proofing of the invention is provided with adhesive phase, can be attached directly on existed building plank, convenient
It uses.
(5) though the heat conduction fuse metal silk cost of the present invention is higher than conventional thermal conductives metals such as copper, heat transfer efficiency is also not as good as copper
Equal conventional thermal conductives metal, but since fusing point is low, starts the starting stage i.e. fusible for decomposing or starting loss in fire retardant, cause
So that composite flame-proof oxidant layer is lost support, fire retardant all comes down in torrents to the space that catches fire rapidly, fire-retardant effect is reached with most fast speed
Fruit, whole flame retardant effect are better than the wire using copper.
