Abstract
The invention provides a novel polyethylene and polyester waterproof coiled material, which belongs to the technical field of waterproof materials. The coiled material comprises a polyester non-woven fabric, a polyethylene anti-seepage film and a hanging belt, wherein the central part of the hanging belt is arranged between the polyester non-woven fabric and the polyethylene anti-seepage film, and two ends of the hanging belt both penetrate the polyester non-woven fabric. The waterproof coiled material is characterized in that the polyethylene anti-seepage film and the polyester non-woven fabric are welded together by ultrasonic waves with intensity greater than 20 MPa and the waterproof coiled material is provided with ultrasonic welding spots. The novel polyethylene and polyester waterproof coiled material has the advantages of convenience in construction, good waterproof effect, simple structure, conservation of time and labor, saving of production cost and wide market space.
Description
Technical field
The present invention relates to a kind of structure of waterproof roll, the structure of especially a kind of novel polyethylene, polyester waterproof coiled material, belongs to waterproof material technical field.
Background technology
Composite geo-membrane refers to the waterproof roll be combined into one by one of polyethylene (PE), polyvinyl chloride (PVC), haloflex (CPE), ethylene-propylene copolymer (EPC) several antiseepage film and polyester or polypropylene non-woven fabric.If directly composite geo-membrane is laid on concrete, waterproof effect is poor, once be punctured, easy to leak.The existing waterproof roll for constructing tunnel, generally be made up of non-woven fabrics and antiseepage film, that face that antiseepage film contacts with non-woven fabrics is provided with connection strap, connection strap two ends are fixed in antiseepage film, then the middle part of non-woven fabrics, connection strap is passed successively with one end of suspender belt, last pass non-woven fabrics (being arranged in the middle part of suspender belt between polyester non-woven fabric and polyethylene antiseepage film and being connected with connection strap, suspender belt two ends are each passed through non-woven fabrics) again.In use, directly waterproof roll is laid on the construction surface in tunnel, and the two ends of suspender belt are connected on constructing tunnel face.The waterproof roll of this structure, complex structure, first needs connection strap two ends to be fixed in antiseepage film, then also need a large amount of manpower that suspender belt is passed connection strap, non-woven fabrics and antiseepage film are linked together, not only consume material, also waste time and energy, and increase production cost.
Summary of the invention
The object of the invention is, in order to for above-mentioned the deficiencies in the prior art, to provide one to save production cost, structure is simple, time saving and energy saving novel polyethylene, polyester waterproof coiled material.
The object of the invention is to be achieved through the following technical solutions: a kind of novel polyethylene, polyester waterproof coiled material, comprise polyester non-woven fabric, polyethylene antiseepage film, suspender belt, be arranged between polyester non-woven fabric and polyethylene antiseepage film in the middle part of suspender belt, suspender belt two ends are each passed through polyester non-woven fabric, it is characterized in that, the ultrasonic bonding that described polyethylene antiseepage film, polyester non-woven fabric are greater than 20MPa by intensity links together, and described waterproof roll is provided with the solder joint of ultrasonic bonding.
Hot melt adhesive layer is provided with between described polyethylene antiseepage film and polyester non-woven fabric.
On described waterproof roll, the solder joint of ultrasonic bonding is dot matrix distribution.
The solder joint of ultrasonic bonding on described waterproof roll is star, triangle, circle or square.
The solder joint integrated distribution of ultrasonic bonding on described waterproof roll is at the middle part of waterproof roll.
Distance between the solder joint of adjacent two rows is 20-50mm, and the distance between the solder joint of adjacent two row is 20-50mm.
The thickness of described polyester non-woven fabric is 0.1-0.5cm.
The thickness of described polyethylene antiseepage film is 0.3-0.7cm.
The length of described suspender belt is 30-60cm, and the width of suspender belt is 0.5-3.5cm.
The present invention adopts the complex method of ultrasonic bonding polyethylene antiseepage film and polyester non-woven fabric to be combined with each other, ultrasonic bonding is the body surface utilizing dither wave loops to weld to two need, when pressurizeing, make the mutual friction of two body surface phases and the fusion that formed between molecular layer.Ultrasonic bonding speed is fast, and weld strength is high, good airproof performance, and polyester non-woven fabric and polyethylene antiseepage film can be made firmly to link together.
The present invention replaces traditional welding/technique for sticking, without the need to arranging connection strap, with low cost, cleanliness without any pollution and can not disfiguring workpiece; Welding process is stablized, and all welding parameters all carry out tracing and monitoring by software systems, once find that fault is easy to carry out getting rid of and safeguarding.PUR be arranged so that the connection between polyethylene antiseepage film and polyester non-woven fabric is more firm.During use, waterproof roll is laid on the construction surface in tunnel, and suspender belt two ends are fastened on constructing tunnel face.Distance between the solder joint of adjacent two rows is 20-50mm, distance between the solder joint of adjacent two row is 20-50mm, the waterproof roll that the pad of dot matrix distribution makes to be laid on tunnel top is stressed more equal, and the main integrated distribution of pad is at the middle part of waterproof roll, tunnel is generally arch, waterproof roll is laid and is suspended on the arch face in tunnel, its stress point mainly concentrates on middle part, and both sides need not pad too much, namely the tie point that the both sides of polyester non-woven fabric and polyethylene antiseepage film need not be too many, more time saving and energy saving like this, save cost.The thickness of polyester non-woven fabric is 0.1-0.5cm, the thickness of polyethylene antiseepage film is 0.3-0.7cm, and the length of suspender belt is 30-60cm, and the width of suspender belt is 0.5-3.5cm, these data make the result of use of waterproof roll more, the achievement being through a large amount of experiments and repeatedly studying.
The present invention is used for constructing tunnel, easy construction, good water-proof effect, and structure is simple, time saving and energy saving, has saved production cost, has had the wide market space.
