In the following, the preferred embodiment of the present invention is described in detail.The example of these preferred embodiments is in attached drawing In illustrated.The embodiments of the present invention described shown in attached drawing and with reference to the accompanying drawings are only exemplary, and this The technical spirit and its primary operational of invention are not limited to these embodiments.
Here, it should also be noted that, in order to avoid having obscured the present invention because of unnecessary details, in the accompanying drawings only It shows the structure and/or processing step closely related with scheme according to the present invention, and is omitted little with relationship of the present invention Other details.
Embodiment 1
Fig. 1 shows the schematic cross-section with self-adhesive layer modified asphalt waterproof coiled material of an embodiment of the present invention.Such as Fig. 1 Shown, which is made of three parts, first part, that is, coiled material upper surface layer, and second part is the bitumen layer of centre, the Three parts are undersurface layer, this three parts forms the modified asphalt waterproof coiled material with self-adhesive layer.
Upper surface layer includes enhancing film 1, and enhancing film 1 covers the intermediate region of bitumen layer and exposes the edge of bitumen layer both sides The marginal portion (overlap edge) of partly (marginal portion of exposing is overlap edge), exposing is covered by isolated border film 4a, 4b.At this In invention embodiment, as an example, enhancing film 1 can be HDPE (high density polyethylene (HDPE)), PET (poly terephthalic acid second two Ester), polymeric membranes or the sheet material such as PP (polypropylene), isolated border film can be that PET applies silicon oil membrane.It can be monofilm to enhance film, Can also be multilayer complex films.When it is PET film to enhance film, which can be PET originals film, PET-PE composite membranes or PET platings Aluminium film, but the present invention is not limited thereto.
Pitch layer segment can be two or more layers structure.In the case of two layers, from top to bottom, first layer can be to change Property asphalt material or special asphalt material 2-1, the second layer is self-adhesion asphalt material 2-2.Modified asphalt layer 2-1 may be, for example, SBS and be modified drip Cobalt blue pigment or APP modified pitch material etc..Special asphalt material for example can be root-resistant type asphalt material, salt tolerant alkaline modified materials, flame retardant type Modified materials etc..In the case where pitch layer segment is multilayer, the bottom is self-adhesion bitumen layer, other layers can be modified pitch material And/or special asphalt material.In embodiments of the present invention, the thickness of self-adhesion bitumen layer is in 0.4mm or more.
Undersurface layer is formed by isolation film 3.Isolation film 3 can apply silicone oil PE (polyethylene) or PET isolation films.
In the embodiment shown in fig. 1, modified as an example, waterproof roll integral thickness may be, for example, 1.0~2.0mm Asphalt thickness is, for example, 0.6~1.6mm, and self-adhesion drip layer thickness is, for example, 0.4~1.0mm, and coiled material overall width is to be, for example, 1000mm, HDPE or PET enhancing film width are, for example, 950mm, and isolated border film width is for example respectively 50mm and 70mm, PE isolation Film width is, for example, 1060mm.These numerical value are merely illustrative, are not intended to limit the present invention, and waterproof roll of the invention can root It is flexibly set according to actual needs.
As described above, the modified asphalt waterproof coiled material disclosed by the invention with self-adhesive layer possesses modified bituminous pitch coiled material simultaneously The advantages of with self-adhesion asphalt felt, easy to use, sandwich of layers is common modified pitch material or special multi-modified asphalt, can be improved The heat resistance and ageing-resistant performance of coiled material, expand the application range of no-wadding adhesive coiled material, while reducing production cost.
Embodiment 2
As shown in Fig. 2, in addition to including the structure in Fig. 1, the waterproof roll in the present embodiment is also provided on enhancement layer Overlap line.Enhance 1 both sides of film and exposes bitumen layer, the first overlap edge 2a and the second overlap edge 2b.
Two overlap joint lines, i.e., the first overlap joint line 1a and second are respectively arranged at two overlap edge 2a, 2b on enhancing film 1 Overlap line 2b.First overlap joint line 1a and the second overlap joint line 2b are parallel with coil edge.
As shown in Fig. 2, the first overlap edge 2a and the second overlap edge 2b can be in unsymmetric structure (or being inclined symmetrical structure), That is the first overlap edge 2a's and the second overlap edge 2b is of different size.As an example, the first overlap edge 2a and the second overlap edge 2b Width may respectively be 2cm and 5cm, and the width value enumerated here is only preferable example, is not intended to limit the present invention.Another party Face, the first overlap joint line 1a and the second overlap joint line 1b can be symmetrically disposed on the enhancing film of waterproof roll namely the first overlap joint line Distances of the overlap joint line 1b of 1a and second away from corresponding coil edge can be equal.As an example, the first overlap joint line 1a and the second overlap joint line Distances of the 2a away from corresponding coil edge is 8-10cm, which is only preferable example, is not intended to limit the present invention.
In embodiment of the present invention, the first overlap joint line and the second overlap joint line can be formed in increasing by the modes such as coating or printing On strong film 1, but the present invention is not limited thereto.
It, can be by the first overlap edge of a waterproof roll in the state of mutually overlapping a waterproof roll with another waterproof roll It mutually overlaps with the second overlap edge of another waterproof roll, by means of overlapping line, can accurately be overlapped.Overlapped in construction When, short overlap edge side adheres to long overlap side side, and two overlap joint lines are just overlapped, need not measure, so that construction effect Rate is promoted.
Short overlap edge (the first overlap edge in such as Fig. 2) side can be adhered to long overlap side by the present invention in coiled material lapping (the second overlap edge in such as Fig. 2) side makes two overlap joint lines just be overlapped, need not measure, so as to without measuring In the case of realize precisely overlap joint, improve construction efficiency.
Further, embodiment of the present invention also specification lap width, not only solves the problems, such as coiled material alice, and The reliability for improving waterproof has widened the application range of no-wadding adhesive coiled material.
Generally speaking, the waterproof roll that the disclosed band of the present embodiment overlaps line can not only improve the heat resistance of coiled material and resistance to Ageing properties can also improve construction efficiency, improve the normalization of construction, can be widely used for all kinds of buildings non-exposed level, Underground and indoor engineering waterproof.
It should be noted that above-described embodiment is only the scope of the claims illustrated the present invention without limiting the present invention, Ren Heji It, should all be in the scope of patent protection of the present invention in the equivalents technology of the present invention.
