Abstract
The invention provides a thermoplastic polyurethane (TPU)-modified asphalt waterproof coiled material. The TPU-modified asphalt waterproof coiled material comprises a blank base, an asphalt layer coated on the blank base and an isolation material. The asphalt layer comprises: by mass, 8 to 12% of 10# petroleum asphalt, 30 to 50% of 90# petroleum asphalt, 6 to 10% of 46# machine oil, 25 to 35% of mountain flour and 6 to 14% of TPU. Compared with a thermoplastic styrene-butadiene rubber (SBS)-modified asphalt coiled material, the TPU-modified asphalt waterproof coiled material has higher heat resistance, low-temperature flexibility, tensile strength and fluidity of molten asphalt.
Description
Technical field
The present invention relates to the building waterproof coil field, particularly, is a kind of modified asphalt waterproof coiled material that comprises tire base and bituminous water-proof coating.
Background technology
Waterproof roll mainly is to locate for construction wall, roofing and tunnel, highway, refuse landfill etc., play a kind of flexible building material product that is curled into web-like of resisting extraneous rainwater, ground water seepage, being connected as ne-leakage between engineering foundation and the building, is the barrier of whole engineering waterproofing.
Present waterproof roll is mainly asphalt water-proof coiled material, comprise the tire base that is made of materials such as polyester felt, Chopped Strand Mat or fiberglass reinforcing polyester felts, dip-coating in the bitumen layer of tire primary surface, and the spacer material layer of upper and lower surface consists of.Wherein for the variation of the component of bitumen layer, can affect to a great extent the performance of waterproof roll, such as heat resistance, low temperature flexibility, impermeability, tensile property etc.For present modified asphalt waterproof coiled material, primary raw material adopts the SBS(thermoplastic styrene butadiene rubber of more amount in the bitumen layer except pitch) as solvent, its content is about about 10%, this kind coiled material is aspect heat resistance, and 100 ℃ of left and right sides tire bases do not fire, pitch is without trickling, low phenomenon; The low temperature flexibility aspect keeps low temperature flexibility about-25 ℃; Tensile strength is at 350N/50mm-900N/50mm; This kind performance parameter is at some comparatively under the rugged environment, still be difficult to resist, as under the impact of the north than cold air, temperature may be lower than subzero 30 ℃, coiled material is easily embrittlement just, and at Equipment for Heating Processing places such as close boilers, local ambient temperature may be higher than 100 ℃, then may cause the burning of tire base; In addition, in the dipping process process, SBS type modified pitch is under the melting dip-coating state about 190 ℃, and is mobile relatively poor, is unfavorable for that evenly entirely dip-coating is in the tire primary surface at the bitumen layer material; Therefore, present SBS type modified asphalt waterproof coiled material still haves much room for improvement.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of thermoplastic polyurethane modified asphalt waterproof coiled material, this kind waterproof roll can further improve its heat resistance, low temperature flexibility, tensile strength than SBS type modified bituminous pitch coiled material, and improves the flowability under the pitch molten condition.
The technical solution adopted for the present invention to solve the technical problems is: this thermoplastic polyurethane modified asphalt waterproof coiled material comprises tire base, the bitumen layer of dip-coating on the tire base, and isolated material;
Described bitumen layer comprises 10# asphalt, 90# asphalt, 46# machinery oil, stone flour; Also comprise hot thermoplastic polyurethane (IPU); The content of each component is as follows by mass percentage:
10# asphalt: 8%-12%;
90# asphalt: 30%-50%;
46# machinery oil: 6%-10%;
IPU:?6%-14%;
Stone flour: 25%-35%.
As preferably, the mass percent content of described IPU is 8%-10%, and under this content, the combination property of coiled material is best.
As preferably, described tire base is made of polyester felt, Chopped Strand Mat or fiberglass reinforcing polyester felt.
As preferably, described isolated material is made of in polyethylene film, fine sand and the mineral pellet one or more.
Beneficial effect of the present invention is: this thermoplastic polyurethane modified asphalt waterproof coiled material has further improved its heat resistance, low temperature flexibility, tensile strength by after the component of bitumen layer is improved, and has improved the flowability under the pitch molten condition.

Fig. 3 is the combination property basic parameter table of SBS type modified asphalt waterproof coiled material.
Among the figure 1,10# asphalt; 2,90# asphalt; 3,46# machinery oil; 4, thermoplastic polyurethane (IPU); 5, stone flour.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one:
This thermoplastic polyurethane modified asphalt waterproof coiled material comprises tire base, the bitumen layer of dip-coating on the tire base that is made of polyester felt, Chopped Strand Mat or fiberglass reinforcing polyester felt, and isolated material;
The formation of described bitumen layer comprises 10# asphalt 1,90# asphalt 2,46# machinery oil 3, stone flour 5 shown in Fig. 1 embodiment; Also comprise hot thermoplastic polyurethane (IPU) 4; The content of each component is as follows by mass percentage:
10# asphalt: 10%;
90# asphalt: 40%;
46# machinery oil: 10%;
IPU:?10%;
Stone flour: 30%.
Described isolated material is made of in polyethylene film, fine sand and the mineral pellet one or more, decides on concrete field of employment.
Above-mentioned thermoplastic polyurethane modified asphalt waterproof coiled material according to the test method of GB18242-2008, is tested test specimen, and its Specifeca tion speeification that reaches as shown in Figure 2.Contrast SBS type modified asphalt waterproof coiled material shown in Figure 3, as seen, this thermoplastic polyurethane modified asphalt waterproof coiled material all is improved at aspects such as heat resistance, low temperature flexibility, tensile strength; And in process of production, under 195 ℃ of molten conditions, in the asphalt dip coating process, the flowability of asphalt grout significantly improves, and has more uniform dip-coating effect.
In another embodiment, the mass percent of IPU is got 8%, and carried out many groups of tests, combination property mean parameter and Fig. 2 of coiled material are suitable as a result, and when the mass percent of IPU was got beyond the 8%-10%, performance subsided a little, but still is better than SBS type modified asphalt waterproof coiled material.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
