Description
Technical field
The present invention relates to fire proofing material manufacturing field, and in particular to a kind of based on the anti-of PAM- inorganic matrixes phase separation polymerization
Flint glass film and its preparation method and application.
Background technology
One kind of flame resistant glass category safety glass, it is that one kind can stop flame, smog, heat radiation, prevent propagation of flame,
Within a certain period of time, the special glass with the transparency of integrality, stability is kept, and there should be certain shock resistance strong
Degree, remains to play a protective role within a certain period of time under 1000 DEG C of flame baking.Flame resistant glass is now just progressively extensive
Applied to construction sites such as large public building cut-off, fire compartment, outdoor curtain walls, flame resistant glass with transparent for characteristic, it is maximum
Meet to limit Building Fire Protection and the harmony of the aesthetics of architecture.
By structure point, flame resistant glass includes two categories below：Single-sheet fire-resistant glass and composite fireproof glass.Single-sheet fire-resistant glass
The shortcomings that be that can only obstruct flame, it is but not heat-insulated, and antidetonation, shock resistance are poor.Composite fireproof glass includes using sandwich method
The A class doubling method compound heat-insulation types and A classes prepared with grouting method does not send out pouring type flame resistant glass black.Sandwich method is prepared compound anti-
Flint glass is although heat-insulated, antidetonation, shock resistance, but fire resistance is generally poor；And pouring type flame resistant glass prepared by grouting method, although
It has preferable fire integrity and preferable effect of heat insulation, but due to containing substantial amounts of moisture in its grouting so that fire prevention
The thickness of glass is big, and weight is big, and which has limited its installation cost and use range.Meanwhile due to being to customize during processing
Double glazing box in perfusion as formed gel layer after fire-resistant fluid, this causes the processed complex of filling type flame resistant glass, and
And the compound glass after sizing the shortcomings of can not arbitrarily cutting.
The content of the invention
In view of the shortcomings of the prior art, the present invention proposes a kind of flame resistant glass for the polymerization that is separated based on PAM- inorganic matrixes
Film and its preparation method and application, the flame resistant glass film can be by after any cut, and doubling becomes compound between two blocks of glass
Flame resistant glass.Such a flame resistant glass is manufactured simple, and weight is small, area is big, variable properties, processing is installed and transporter
Just.Concrete technical scheme is as follows：
A kind of preparation method of the flame resistant glass film based on the polymerization of PAM- Polymer phase separations, this method are specific as follows：Will
The saturated aqueous solution of the acrylamide and N, N ' of 30~60 parts by weight-methylene diacrylamide mixture, 40~70 parts by weight and
pH>9 inorganic matrix saturated aqueous solution is sufficiently mixed, then the mass fraction of 0.2~1.5 parts by weight of addition is into mixed liquor
10% initiator, after stirring, by salivating shaping or mould molding, polymerization obtains the phase separation polymerization of PAM- inorganic matrixes
Flame resistant glass film；
Described inorganic matrix is made up of one or both of waterglass and aluminium salt by any proportioning.
Further, described inorganic matrix also includes sodium chloride, and the content of described sodium chloride is no more than inorganic matrix
The 15% of gross weight.
Further, described aluminium salt is aluminium chloride or aluminum sulfate or alum or water miscible meta-aluminate.
Further, described waterglass is sodium silicate or KP1.
Further, described initiator is hydrogen peroxide, potassium peroxydisulfate or ammonium persulfate.
The flame resistant glass film that a kind of preparation method by above-mentioned any one obtains.
A kind of flame resistant glass made of above-mentioned flame resistant glass film, it is by upper and lower layer glass and doubling upper and lower two
Flame resistant glass film composition between layer glass.
Compared with prior art, beneficial effects of the present invention are as follows：
After the flame resistant glass film polymerizeing that is separated based on PAM- inorganic matrixes of the present invention can arbitrarily be cut, doubling is to two pieces
Between glass, become compound flame resistant glass, preparation technology is simple, obtained flame resistant glass weight is small, area is big, property can
Become, processing is installed and transport is all very convenient.Under the high temperature sintering of fire, inorganic constituents is alkaline, is embedded in compound
Moisture content vaporizes so that macromolecule resin foaming turns into foamed resin.Meanwhile the inorganic substrate of doping is covered in the bubble of foamed resin
On foam wall, the flame-retardant layer of inorganic substrate covering is formed.Meanwhile in the presence of high temperature of fire, inorganic substrate is further sintered
And crosslinking condensation is the refractory material coating of inorganic porous property structure, and the coating is turned into inorganic fire skeleton, improve
The mechanical strength of fireprotection layer, fire resistance and effect of heat insulation, and can play mechanical integrity and insulating refractory in a fire
Effect.
