Description
Technical field
The invention belongs to the fire resistant coating in fire resistant coating field, more particularly, to integrated house based plate.
Background technology
Integrated house (movable dwellings) is generally built by color steel, aluminium and some polymer electrolyte sheet materials, is connected
Water pipe, gas piping, power line, it is possible to move in.Its is cheap, be only with area house 1%-10%, build one it is general
Logical resident room needs ten months even more than 1 year, as long as and building such movable plank house a couple of days.But as safety is anticipated
Know and awareness of saving energy raising, requirement to integrated house also more and more higher.
Polyurethane hard coats be using isocyanates and polyethers as primary raw material, it is many in foaming agent, catalyst, fire retardant etc.
Plant in the presence of auxiliary agent, mixed by special equipment, the high molecular polymer through high pressure painting foam-in-place.Rigid polyurethane
Foam is a kind of novel synthetic material for having and being incubated with water-proof function, and its thermal conductivity factor is low, only 0.018~0.024W/ (m*
K), it is that thermal conductivity factor is minimum in current all insulation materials equivalent to the half of extruded sheet.RPUF master
Apply skin insulation, waterproofing and thermal insulation of roofing integration, heat-insulated heat preservation of refrigeration storage, pipe insulation material, building board,
Refrigerator car and the heat-insulated material of freezer etc..The organic based flame retardant of conventional halogen can cause construction environment severe, cause environmental pollution.And
Inorganic combustion inhibitor such as magnesium hydroxide, aluminium hydroxide etc., the addition big city of this based flame retardant cause the mechanical property of insulation material
Decline with heat-insulating property.Although the insulation selection polyurethane heat insulation material more and more built.However, due to polyurethane heat-insulation
There is the defect of flame retardant effect in material, improve its flame retardant effect and reach and meet the requirements and will seriously reduce its heat insulation effect, therefore, carry
The flame retardant effect of high polyurethane material simultaneously ensures that its heat insulation effect turns into contradiction.
Expanded graphite is a kind of cheap and purposes extremely wide material, is widely used in encapsulant, conductive material, adsorption material
Got the attention in material, catalysis material, medical material etc., especially fire-retardant fireproof material.
Mixed using expanded graphite as fire retardant into polyurethane coating, the problem of often there is phase separation, coating is long
Time stands, and expanded graphite can precipitate, and cause coating uneven, the progress to construction also results in very burden, so as to hinder
It is hindered in the application of paint field.
The content of the invention
It is an object of the invention to provide a kind of fireproof coating and its application method for integrated house profile material, so as to solve
The problem of in certainly above-mentioned background technology.
Technical problem solved by the invention is realized using following technical scheme：
A kind of fire prevention figure layer for integrated house profile material, including
Component A：
And B component：
Isocyanates.
In the present invention, as a kind of perferred technical scheme, the modified expanded graphite is through hydrogen peroxide by expanded graphite
After 50 degree are heated, reacted with epoxy type silane coupler, incited somebody to action by the method for grafting under proton catalyst effect etc.
The PPG key of quality is connected on expanded graphite, so as to obtain modified expanded graphite.
In the present invention, as a kind of perferred technical scheme, the particle mesh of expanded graphite described in the modified expanded graphite
Number is 40-80 mesh, and expansion multiplying power is 250-450 times.
In the present invention, as a kind of perferred technical scheme, the epoxy type silane coupler is γ-glycidyl ether oxygen
Propyl trimethoxy silicane (KH560)
Expanded graphite is modified, epoxy type silane coupler key is connected on expanded graphite, then in proton catalysis
Under conditions of agent (ammonia or acidic materials of catalytic amount), by etc. the PPG key of quality be connected on epoxide group, obtain
To the expanded graphite of modified by polyether glycol, so as to improve the lipophile of expanded graphite.Just in this way, by modified expansion stone
Ink is added in component A, and what the fire retardant can be stablized is present in the mixture, can not without conventional expanded graphite
The problem of enough stable homogeneous are mixed.
In the present invention, as a kind of perferred technical scheme, the foam stabilizer is silicone oil；The foaming agent is octafluoro third
Any one or more in alkane, a fluorine dichloroethanes HCFC-141b, 3-pentafluorobutane；The catalyst is TEDA liquid catalysts
Agent；The light stabilizer is titanium dioxide.
In the present invention, as a kind of perferred technical scheme, the PPG is poly- by initiator of bromo-derivative
Ethoxylated polyhydric alcohol.Its degree of functionality is 2, and hydroxyl value is 180-260mgKOH/g.
The component of A, B two is sufficiently mixed and has just obtained this and is used for the fireproof coating of integrated house profile material.
Invention also provides the application method of the fireproof coating for being used for integrated house profile material.The fire prevention is applied
Material is poured on profile plate, is heated, and is then covered one layer of overlay film in outermost layer, is produced.The coating appearance is smooth, and inside is existed
A large amount of densification bubbles.
In the present invention, as a kind of perferred technical scheme, the heating-up temperature is 40-120 DEG C.
Those skilled in the art should know, when expanded graphite makees fire proofing, be related to graphite and other components
Mix sex chromosome mosaicism, because the salinity of graphite surface is very high, and it is neither lipophilicity substance, nor hydroaropic substance.Therefore,
Expanded graphite is applied to here by the present invention, there is very big difficulty.The present invention is directed to such case, uses epoxy type silane
Coupling agent is bridge, carries out modified by polyether glycol to expanded graphite, i.e., expanded graphite is used into silane coupler, passes through grafting
Method PPG is loaded into expanded graphite top layer.Find that modified expanded graphite and polyethers are more in actual applications
First alcohol combination material has good compatibility, and material can be combined with PPG and produces extraordinary cooperative flame retardant effect, but
The mechanical performance to material does not have significant difference simultaneously.Experiment is proved, is not added with the case of modified expanded graphite, the oxygen of the coating
Index is 29, and oxygen index (OI) reaches more than 40 after addition modified expanded graphite, peak value HRR, peak value life cigarette speed and
CO yields reduce at least 8%, 35% and 16% respectively.
