Description
Technical field
The present invention relates to the fire-resistant water-proof sheet material of a kind of modification waste residue and preparation method.
Background technology
Pitch is a kind of important architectural waterproof material, because its water resistance is excellent, low price and being widely used.Polymer modified asphalt waterproof roll becomes because it possesses excellent high temperature performance the architectural waterproof material received much concern.But polymer modified asphalt waterproof roll is the same with common organic materials, easily can occur aging by the effect of the factors such as UV-light, heat, oxygen, cause that waterproof roll is hardening to become fragile, low temperature flexibility reduces fast, be difficult to the shrinkage of adaptation roof-base in the winter time under low temperature and occur cracking, thus cause waterproof layer to destroy, cause roof leakage, substantially reduce the work-ing life of roof waterpoof material.Therefore, improve the ageing-resistant performance of roofing flux, significant to the weather resistance improving building roof.
Carry out modification with thermoplastic elastomer to pitch, at home and abroad existing history for many years, using maximum is styrene-butadiene-styrene inlay section thermal plastic elastic body (SBS).SBS modifying asphalt has excellent high-and low-temperature resistance performance and elastic recovery properties, is the kind that in current polymer modified asphalt, consumption is maximum.But pitch and elastomer modifier are mainly containing C-H, C-C and C=C, and the effect in use by factors such as UV-light, oxygen, heat causes chemical bond rupture, and composition and structure changes, and causes performance degradation, work-ing life shortens.
Some research reports are had about raising elastomer modified asphalt roof waterpoof material ageing-resistant performance.Chinese patent CN102190957A proposes to add magnesium-aluminum-based laminar double hydroxide in pitch, utilize magnesium-aluminum-based laminar double hydroxide to ultraviolet physical shielding effect, improve the anti-ultraviolet ageing ability of elastomer-modified body pitch, but pitch in use occur except being subject to action of ultraviolet light aging except, also can be subject to the effect generation thermo-oxidative ageing of heat, oxygen, and magnesium-aluminum-based laminar double hydroxide is improving the effect of pitch heatproof air aging performance and not obvious.Oxidation inhibitor is joined in pitch, the thermo oxidative aging ability of pitch can be improved to a certain extent, but because oxidation inhibitor is low molecular weight organic compound, easily to be heated when it mixes under the high temperature conditions with heated bitumen volatilization, and itself also can reduce thermo oxidative aging ability because of aging, cause oxidation inhibitor can not be effective for a long time to the anti-aging effect of pitch.
Elastomerics (SBS) modified asphalt waterproof coiled material because having, drop down, crack resistance at low-temperature is widely used in waterproofing work by good high temperature anti-current.But asphaltic base waterproof roll in use can be subject to the impact of the factors such as light, heat, oxygen and occur aging, cause that waterproof roll is hardening to become fragile, low temperature flexibility significantly reduces.For SBS modified asphalt waterproof coiled material, agingly not only comprise the aging of pitch, also comprise the aging of SBS.For extending the work-ing life of elastomer modified asphalt waterproof roll, pole is necessary the ageing-resistant performance improving elastomer modified asphalt.Laminated dihydroxy composite metal hydroxide (LDHs) is a class supramolecule layer structure material.LDHs forms multi-stage superimposed laminate structure by layered double-hydroxide laminate and interlayer anion, and its inorganic laminate can play physical shielding effect to ultraviolet; If by between organic uv absorbers interposed layer, LDHs will be made to have the dual function of physical shielding and absorption to ultraviolet simultaneously.In addition, ultraviolet is when laminate multistage by LDHs, and higher order reflection and refraction can occur on layer ineface, energy also can weaken.
The present invention utilizes the industrial residues such as slag, flyash and desulfurated plaster to prepare a kind of Calucium Silicate powder sand plate plate, give full play to the synergy between different solid waste, produce and obtain the material of construction meeting national standard, not only can realize the comprehensive utilization of industrial solid wastes, the pollution of solid waste discharge to environment can also be reduced.
