TPO single side self composite of water-proof coiled material
Technical field
The utility model relates to a kind of waterproof roll, relates in particular to a kind of compound two-layer TPO single side self composite of water-proof coiled material with independent waterproof ability.
Background technology
Existing design specifications has a lot of schemes to adopt the collocation of inhomogeneity coiled material, utilizes without class coiled material advantage separately and forms mutual supplement with each other's advantages.But because the construction difference of inhomogeneity coiled material, what have is far from each other especially, and this has just brought the place of inconvenience profit to construction.In order to tackle the inconvenience in the construction, the TPO self-adhesion composite of water-proof coiled material of developing.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of two kinds of coiled materials that have independent waterproof ability separately are one by special process is compound, thus the TPO single side self composite of water-proof coiled material of the purpose that can reach the twice waterproof by once constructing.
The purpose of this utility model provides following technical scheme to realize: a kind of TPO single side self composite of water-proof coiled material, described waterproof roll comprises the self-adhesive rubber asphalt coiled material layer, the TPO coiled material layer, the multilayer layer structure is compound to be one, be compounded with the function transition zone between TPO coiled material layer and the self-adhesive rubber asphalt coiled material layer, be compounded with reserved function transition bonding layer above the TPO coiled material layer.
Adopt technique scheme, compared with prior art, the beneficial effects of the utility model are:
1, made full use of the TPO waterproof roll high strength, high-elongation, endurable thorn, weatherability is strong and the high-elongation of self-adhesive rubber asphalt waterproofing coiled material, crack resistance are strong, have advantages such as self-healing property, creep properties.
2, the self-adhesive rubber asphalt coiled material layer can be directly and concrete completely bond, realized that waterproof roll and concrete structure layer are well-bonded, effectively prevent to scurry the water phenomenon.
3, easy construction, abundant, saving duration of worker's method.Can adopt completely sticking method, wet shop method, overlay worker's method construction such as anti-sticking method according to the project situation difference.
4, overlap joint is easy.Can directly self-adhesive rubber asphalt coiled material layer and the overlap joint of the reserved function transition zone above the TPO coiled material layer be got final product, effectively improve bond strength, work progress is easier, and overlap joint is reliable, and can prevent plasticising oil swelling TPO coiled material layer in the self-adhesive layer, make its variable color, buckling deformation.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model
Among the figure, self-adhesive rubber asphalt coiled material layer 1, function transition zone 2, TPO coiled material layer 3 reserved function transition bonding layers 4.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further elaborated.
Present embodiment is a kind of TPO single side self composite of water-proof coiled material, and its structure is seen Fig. 1, is to be composited according to the order of sequence by one deck TPO coiled material layer 3, two layer function transition zones and one deck self-adhesive rubber asphalt coiled material layer 1.Between TPO coiled material layer 3 and self-adhesive rubber asphalt coiled material layer 1, be compounded with function transition zone 2, the top complex reservation function transition bonding layer 4 of TPO coiled material layer 3.
TPO coiled material layer 3 is homogeneous TPO coiled material or interior enhancing TPO coiled material.Adopting thickness is the interior enhancing TPO coiled material of 1.2~1.5mm, and it is the waterproof roll that one deck has independent water-proof function, has very high hot strength, elongation per unit length, tearing strength, puncture resistance and weather resistance.
Function transition zone 2 and reserved function transition bonding layer 4 are respectively metallized film, zinc-plated film, copper facing film or barrier multilayer (seven layers) co-extrusion films.Its role is to improve combined strength bination from sizing and TPO coiled material; Stop the speedup oil in the self-adhesive rubber asphalt coiled material layer 1 to permeate to TPO coiled material layer 3, and then swelling TPO coiled material layer 3, the coiled material buckling deformation caused.Reserved function transition bonding layer 1 long 5~10cm.
Self-adhesive rubber asphalt coiled material layer 1 thickness is 1.5mm.Self-adhesive rubber asphalt coiled material layer 1 also is the waterproof roll that one deck has independent water-proof function.
The utility model is one with self-adhesive rubber asphalt coiled material layer 1 and 3 two kinds of coiled materials that have independent waterproof ability separately of TPO coiled material layer by special process is compound, thereby can reach the purpose of twice waterproof by once constructing.Not only alleviate construction intensity, accelerated construction speed.And overlap joint is reliable, and can prevent plasticising oil swelling TPO coiled material layer in the self-adhesive layer, makes its variable color, buckling deformation.
TPO single side self composite of water-proof coiled material adopts following method construction: during construction, and after the basic unit of cleaning earlier, the brushing base treatment agent; Again TPO self-adhesion composite of water-proof coiled material is spread out and overlay the location; After slowly extracting barrier film out from its bottom then, use the pressure roller compacting; Between coiled material self-adhesive rubber asphalt coiled material layer 1 and reserved function transition zone 4 directly overlapped and get final product.
Through evidence, the utlity model has high strength, high-elongation, puncture-resistant, weatherability high-elongation, crack resistance strong and self-adhesive rubber asphalt waterproofing coiled material strong, have an advantage such as self-healing property. The setting of the reserved function transition bonding layer 1 of especially long 5~10cm makes that overlap joint is convenient and reliable, lap-joint does not have the variable color warpage, engineering method is various, saved the duration.
