Abstract
The invention relates to a high polymer modified asphalt waterproof coiled material for a bridge of a railway. Long fiber polyester non-woven fabric is taken as a matrix; dipping material layers are adhered on the upper and lower surfaces of the matrix; coating material layers are adhered on the outer surfaces of the dipping material layers; a facing insulation material of quartz sand of 40 to 80 meshes is adhered on the outer surfaces of the coating material layers; and the coating material layer comprises the following components in percentage by mass: 40 to 55 percent of asphalt, 10 to 15 percent of engine oil, 10 to 15 percent of SBS synthetic rubber, 5 to 10 percent of polypropylene, 5 to 20 percent of rubber powder and 5 to 15 percent of filler. The high polymer modified asphalt waterproof coiled material for the bridge of the railway has the advantages of no fracture when bent at -35 DEG C, no deformation at the high temperature of 120 DEG C, using interval of between -20 DEG C and +60 DEG C, flexibility and function still maintained at -60 DEG C, high water resistance, no water absorption, no performance attenuation under long-time water erosion, no penetrating possibility under the pressure of 0.4MPa, and capability of effectively resisting the load of traveling trains.
Description
Technical field
The present invention relates to a kind of railway bridges and culverts waterproofing course, relate in particular to a kind of asphalt water-proof coiled material.
Background technology
Reinforced Concrete Bridge causes various diseases because of suffering the rainwater etch, and seriously shorten application life, needs the bridge culvert is done waterproofing work.And the high and low temperature resistance of waterproofing course, ageing-resistant performance, with durable attachment adhesive property, the fatigue resistance the dynamic load effect under on the concrete bridge deck be the key index of its waterproofing course quality of measurement.
The tire base that prior art medium pitch waterproof roll is made of polyester blank or glass fiber blank, tire base upper and lower surface is pasted with impregnated material layer, and the external surface of impregnated material layer is pasted with modified bitumen coating material layer, and coating material layer external surface is pasted with the clad can isolated material.Its modified bitumen contains pitch, machine oil, SBS synthetic rubber, polypropylene, rubber powder and filler etc. in coating and expecting.The problem of its existence mainly is that the material of coating can not satisfy high temperature performance simultaneously, or high temperature trickling phenomenon is arranged, or low temperature flexibility is poor, the low temperature flexibility temperature now the end only be-25 ℃, low temperature is crisp firmly, cracking etc., is unfavorable under the low temperature constructing; Bridge surface waterproof layer is easy under the traffic dynamic loads destroy bearing, and will be pulsed hydraulic action behind the waterproofing course local damage and peels off expansion etc.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of railway bridges and culverts polymer modified bituminous waterproof sheet material, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
It is the tire base that the present invention adopts long polyester nonwoven, and tire base upper and lower surface is pasted with impregnated material layer, and the external surface of impregnated material layer is pasted with the coating material layer, and coating material layer external surface is pasted with the clad can isolated material of 40-80 order quartz sand; The coating material layer comprises: pitch, machine oil, SBS synthetic rubber, polypropylene, rubber powder and filler; The mass percent interval of each component is: pitch 40～55%, machine oil 10～15%, SBS synthetic rubber 10～15%, polypropylene 5～10%, rubber powder 5～20%, filler 5～15%.
Compared with prior art, beneficial effect of the present invention is: do not rupture-35 ℃ of following bendings, 120 ℃ of high temperature are indeformable, and-20 ℃ of use intervals to+60 ℃ of scopes still keep toughness and function under-60 ℃; Excellent water resistance does not absorb water, and performance is unattenuated under the long-term erosion of water, is not penetrated under the effect of 0.4MPa pressure; Excellent bond performance, firm and durable with basic unit bonding, 2,000,000 times repeatedly under pressure and the tension tack coat do not have cracking, be highly resistant to the load of driving.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is described in further detail:
The present invention is achieved by the following technical solutions:
It is the tire base that the present invention adopts long polyester nonwoven, and tire base upper and lower surface is pasted with impregnated material layer, and the external surface of impregnated material layer is pasted with the coating material layer, and coating material layer external surface is pasted with the clad can isolated material of 40-80 order quartz sand; The coating material layer comprises: pitch, machine oil, SBS synthetic rubber, polypropylene, rubber powder and filler; The mass percent interval of each component is: pitch 40～55%, machine oil 10～15%, SBS synthetic rubber 10～15%, polypropylene 5～10%, rubber powder 5～20%, filler 5～15%.
The present invention is compared with prior art: adopted long polyester nonwoven, must not use short fiber polyester non-woven fabric or glass fiber blank; The material formula ratio of coating is different from general modified bitumen prescription fully; The clad can isolated material quartz sand of preferred suitable fineness.Based on above change, the present invention has realized satisfying simultaneously the high temperature performance of coiled material.
Preparation method of the present invention is:
Make earlier the high-polymer modified pitch material of coating: squeeze into No. 90 pitches of 50 parts of PetroChina Company Limited., be the modified bitumen base-material; 13 parts of Zhenghai refinery machine oil improve the coiled material cryogenic property; Be warming up to 160 ℃-200 ℃ dehydrations 1 hour, add 15 parts of Beijing swallow SBS modifier, starting colloid mill grinds, temperature is controlled at 180 ℃-200 ℃, grinds to add 7 parts of Hebei after qualified again and produce polypropylene and continue to grind, and polypropylene can improve the coiled material high-temperature behavior, add 5 parts of rubber powders at last and 10 parts of fillers are regulated rare denseness, rubber powder is beneficial to asphalt modification, and filler plays filling effect, is beneficial to the coiled material moulding.Select suitable long polyester nonwoven tire base cloth (being to sell), saturating with the preimpregnation oil immersion, extract, coat certain thickness above-mentioned modified bitumen again on both sides, the two sides spreads that 40-80 order quartz sand clad can, cooling, rolling, volume are cut, packing etc., formulates the coiled material of specific thicknesses and length.
