Ethane is as organic intercalation agent and above-mentioned montmorillonite with 1:1-4 mass ratio carries out organically-modified；Above-mentioned TDE is inserted
Layer modified montmorillonoid schematic diagram is as shown in Figure 3.Above-mentioned TDE-organo montmorillonite fire retardant can be in the best time in gas
Phase and condensed phase play flame retardant effect simultaneously, can effectively prevent modified pitch from producing melting drippage, it is to avoid pitch drops onto building
It is interior to trigger secondary resume combustion.Really solve the present situation of current bituminized shingle fire protecting performance difference, it is ensured that the fire safety of building, with compared with
Big social benefit.Wherein, TDE monomer due to the bond energy of the C-Br keys of itself it is relatively low, decomposition temperature is 300
DEG C or so, in burning, molecule starts to decompose, and the free radical that burning is produced can be caught, so as to delay or suppress the anti-of pyric chain
Should, while the HBr gases discharged are fire retardant, the surface that can be covered in material forms gas phase barrier layer, plays barrier and dilution
The effect of oxygen concentration.The reaction being directed to：
O+HBr=HO-+Br chain tra nsfers
There is highly reactive HO free radicals to play key in combustion for HO+HBr=H2O+Br chain terminations
Effect；When HO is replaced by the poor Br of reactivity, free chain reaction is just terminated.
Inorganic silicon own montmorillonite MMT (its chemical general formula is [(Al2-y, Mgy) 2] [Si4O10 (OH) 2] nH20)
Hydrochlorate lamella is preferable to the diffusion barrier properties of gas and small molecule, can form non-flammable carbonization when heated in combustible surface
Film, contact of the starvation with combustible.
The waterproof layer of the bituminized shingle of the present invention uses self-adhesive modified asphalt coating, possesses splendid adhesive property, upper surface
The surface of modified asphalt layer can be closely bonded with the mineral particle bed of material being overlying on thereon, it is ensured that the adhesion property of mineral pellet is closed
Lattice；The surface of lower surface modified asphalt layer is adhered to using yellow ground separation layer, using when convenient construction.
A side of upper surface and two sides of lower surface for the bituminized shingle of the present invention devises modified pitch certainly
Adhesive tape, the caking property between the self-adhesive tape of lower surface modified asphalt layer and basic unit is excellent, and intensity is more than 3N/mm, it is ensured that fabulous
Wind resistance take off ability, wind uplift resistance 97km/h tests pass through；The lower self-adhesive tape of upper bituminized shingle during construction paving bituminized shingle
Adhesive property between the upper self-adhesive tape of next bituminized shingle is compared excellent, and the stripping between upper self-adhesive tape and lower self-adhesive tape is strong
Degree is more than 2.0N/mm.
The bituminized shingle low temperature flexibility of the present invention is good, overcomes the easy season cracking of conventional bituminized shingle and breakable shortcoming.
The modified pitch of the present invention is not in the situation that mineral pellet comes off preferably with the adhesiveness of mineral pellet, is protected
Attractive in appearance and ageing resistace is demonstrate,proved, decay is small to reach the longer waterproof life-span.
The main raw material(s) that the present invention is used is all the common raw materials for producing modified asphalt waterproof coiled material, material source side
Just and cost is relatively low；And the adding proportion of fire retardant is also less in being formulated, influence will not be produced on modified pitch self-adhesive layer performance.
The not most part of the embodiment of the present invention, those skilled in the art can select from prior art as needed.
Disclosed above is only the embodiment of the present invention, but protection scope of the present invention is not limited thereto, and is appointed
What those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should using above-mentioned scope of the claims as
It is accurate.
