Abstract
The invention provides a method for producing a thermoplastic polyurethane modified asphalt waterproof coiled material, which comprises the following steps: 1) preparing an asphalt layer with 8-12% of 10#petroleum asphalt, 30-50% of 90#petroleum asphalt, 6-10% of 46#petroleum asphalt, 6-14% of IPU and 25-35% of stone powder according to mass percentage; 2) placing each material in the step 1) in a stirring device, controlling the stirring temperature at 200-220 DEG C, stirring for 2 hours, uniformly mixing to obtain a mixed asphalt liquid, and then discharging; 3) placing the mixed asphalt liquid in a dipping pool of a dipping device, continuously passing a matrix through the dipping pool for completing the dipping technology, performing an adhesion technology of an isolation material after the dipping technology; and 4) cooling, coiling the materials by a material coiling device, and then packaging. Compared with a general SBS type asphalt modified waterproof coiled material, the waterproof coiled material prepared by the method has improvement on heat resistance, low temperature flexibility, tensile strength and the like.
Description
Technical field
The present invention relates to the building waterproof coil production field, particularly, is a kind of production method of modified asphalt waterproof coiled material.
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, and disclose its production method, with the waterproof roll that this kind production method is produced, can improve the comprehensive mechanical property of coiled material.
The present invention adopts following steps to produce this waterproof roll:
One, configuration bitumen layer:
Press mass percent, get 10# asphalt: 8%-12%; 90# asphalt: 30%-50%; 46# machinery oil: 6%-10%; The IPU(thermoplastic polyurethane): 6%-14%; Stone flour: 25%-35%;
Two, each component in the step 1 is put into mixing plant, the control whipping temp stirred 2 hours at 200 ℃ ~ 220 ℃, evenly became mix asphalt liquid, then discharging;
Three, mix asphalt liquid is packed into dipping unit in the dipping system makes the tire base pass through continuously dipping unit, finishes dipping process, and carries out the attach process of isolated material at the dipping process rear;
Four, cooling, and by coiled strip equipment coiled strip, pack again.
As preferably, in step 1, the mass percent content of described IPU is taken as 8%-10%, and under this content, the combination property of coiled material is the most stable.
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.
By the thermoplastic polyurethane modified asphalt waterproof coiled material that said method is produced, warp is compared to common SBS type asphalt modification waterproof roll, and the aspects such as its heat resistance, low temperature flexibility, tensile strength all make moderate progress.
Description of drawings
Fig. 1 is production method step schematic diagram involved in the present invention;
Fig. 2 is the all-round property testing parameter list of this thermoplastic polyurethane modified asphalt waterproof coiled material;
Fig. 3 is the combination property basic parameter table of SBS type modified asphalt waterproof coiled material.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
In embodiment one, the present invention adopts following steps to produce this waterproof roll:
One, configuration bitumen layer:
Press mass percent, get 10# asphalt: 8%-12%; 90# asphalt: 30%-50%; 46# machinery oil: 6%-10%; The IPU(thermoplastic polyurethane): 6%-14%; Stone flour: 25%-35%; The mass percent of each component all is proportions, in this scope, can arbitrarily adjust its content, only need satisfy each component percentage summation and is 100% and get final product; What particularly point out is, in the content of other each component kept substantially constant situation, the content of described IPU was 8% ~ 10% the time, and gained waterproof roll performance is the most stable;
Two, stir discharging:
Each component in the step 1 is put into mixing plant, and the control whipping temp stirred 2 hours at 200 ℃ ~ 220 ℃, evenly became mix asphalt liquid, then discharging;
Three, dip-coating is adhered to:
With pack into dipping unit in the dipping system of mix asphalt liquid, make the tire base pass through continuously dipping unit, finish dipping process, and carry out the attach process of isolated material at the dipping process rear.In this step, described tire base can be made of polyester felt, Chopped Strand Mat or fiberglass reinforcing polyester felt, and described isolated material can or reach the mineral pellet by polyethylene film, fine sand and consist of;
Four, cooling packing:
After finishing dip-coating, attach process, by coiled strip equipment coiled strip, pack again.
Thermoplastic polyurethane modified asphalt waterproof coiled material by said method production, requirement by GB18242-2008D is tested, contrast by Fig. 2, Fig. 3, can find out compared to common SBS type asphalt modification waterproof roll, this thermoplastic polyurethane modified asphalt waterproof coiled material all makes moderate progress at aspects such as heat resistance, low temperature flexibility, tensile strength.
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.
