TPO self-adhesion composite of water-proof coiled material
Technical field
The utility model relates to a kind of waterproof roll, specifically a kind of TPO self-adhesion composite of water-proof coiled material with the metal tire.
Background technology
At present, TPO self-adhesion composite of water-proof coiled material is that two kinds of coiled materials that have independent waterproof ability are separately passed through special process compound to be one, to reach the purpose of twice waterproof through once constructing.TPO self-adhesion composite of water-proof coiled material has that intensity is higher, good extending performance, puncture, have advantages such as self-healing property, easy construction.But also there is following deficiency in this waterproof roll: size changing rate is big, resistant to thermal aging is bad, the coiled material planeness is bad; Cause when constructing easily and unreal empty phenomenon of basic unit's bonding; Especially at parapet; Comparatively obvious when negative and positive angle, water fall mouthful etc. comparatively the complicated construction position, long-term use causes application life easily, and situation such as bulging do not play in length, strain cracking, basic unit.
The utility model content
The utility model is the defective that exists to existing waterproof roll, and the TPO self-adhesion composite of water-proof coiled material of a kind of mechanical strength height, good water-proof effect is provided.
The technical scheme that the utility model adopts is: a kind of TPO self-adhesion composite of water-proof coiled material; It is the multilayer layer structure that is composited by TPO coiled material layer, function transition zone, self-adhesive rubber asphalt coiled material layer and antiseized spacer material layer, and said TPO coiled material layer comprises TPO coiled material layer, following TPO coiled material layer, is arranged on the metal tire basic unit between TPO coiled material layer and the following TPO coiled material layer; Said TPO coiled material layer is the composite bed that is formed by metal tire basic unit and the calendering of upper and lower TPO coiled material layer co-extrusion.
As preferred version, metal tire basic unit is a kind of in copper foil layer or the pure aluminum foil layer.The function transition zone is the barrier PP TYPE.
The thickness of TPO coiled material layer is 1.2-1.5mm.The thickness of self-adhesive rubber asphalt coiled material layer is 1.5-2.0mm.
Compared with prior art; This waterproof roll disclosed in the utility model is that the calendering of composition metal tire base co-extrusion constitutes between two-layer homogeneous TPO coiled material layer, increases the mechanical strength of coiled material, makes coiled material have certain rigid; Reduce the size changing rate of coiled material; Improve the bad performance of resistant to thermal aging, thereby play, the fall effect of the prefabricated typings of complex region such as mouth of negative and positive angle, water at parapet.
The beneficial effect of the utility model is:
1, the TPO self-adhesion composite of water-proof coiled material of band metal tire makes full use of that high strength, high-elongation, puncture, the weatherability of TPO self-adhesion composite of water-proof coiled material is strong, self-adhesive layer has advantages such as self-healing property;
2, as the Copper Foil or the pure aluminum foil of metal tire basic unit, mechanical strength is high, and opposing outside destroy ability is strong, at the waterproof construction position that has operation to intersect, is not easy to destroy;
3, have metal tire basic unit, the rigidity of coiled material is big, plays certain prefabricated styling during construction;
4, coiled material can effectively be avoided the damage of various human factors in work progress, effectively protects the integrality of self-adhesive layer, practices thrift the cost because of the impaired increase of coiled material.
Description of drawings
Fig. 1 is the layer structure sketch map of the utility model.
Among the figure: go up TPO coiled material layer 1, metal tire basic unit 2, following TPO coiled material layer 3, function transition zone 4, self-adhesive rubber asphalt coiled material layer 5, antiseized spacer material layer 6.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Referring to accompanying drawing 1, this TPO self-adhesion composite of water-proof coiled material, it is the multilayer layer structure that is composited by TPO coiled material layer, function transition zone 4, self-adhesive rubber asphalt coiled material layer 5 and antiseized spacer material layer 6.The TPO coiled material layer comprises TPO coiled material layer 1, following TPO coiled material layer 3, is arranged on the metal tire basic unit 2 between TPO coiled material layer 1 and the following TPO coiled material layer 3.The TPO coiled material layer is to roll the composite bed that forms by metal tire basic unit 2 with upper and lower TPO coiled material layer 1,3 co-extrusions.
As preferred version, metal tire basic unit 2 is a kind of in copper foil layer or the pure aluminum foil layer.Tire basic unit is that the effect of metal tire basic unit is the mechanical strength that increases coiled material, makes coiled material have certain rigid, when complex region is constructed, plays prefabricated styling.
Function transition zone 4 is the barrier PP TYPE, its role is to improve the combined strength bination from sizing and TPO coiled material; Prevent that the oil content in the self-adhesive layer from penetrating in the TPO layer.
The thickness of TPO coiled material layer is 1.2-1.5mm, has very high hot strength, elongation per unit length, tearing strength, puncture resistance and weather resistance.
The thickness of self-adhesive rubber asphalt coiled material layer is 1.5-2.0mm, the completely sticking method of suitable usefulness, wet shop method, overlays anti-sticking method construction, efficient is high, speed is fast, with the basic unit bonding firmly and do not have " scurrying water ".
The TPO self-adhesion composite of water-proof coiled material of this band metal tire disclosed in the utility model can adopt the construction of following method: during construction, earlier with parapet, the fall base cleaning of complex region such as mouth of negative and positive angle, water is clean, the brushing base treatment agent; The TPO self-adhesion composite of water-proof coiled material of band metal tire is spread out, and the location is pasted in prefabricated typing; Extract barrier film out from its bottom, installation of membrane is used the pressure roller compacting on basal plane.
Through evidence; When the TPO self-adhesion composite of water-proof coiled material of the utility model band metal tire makes full use of TPO self-adhesion composite of water-proof coiled material advantage; Effectively raise mechanical strength, the opposing outside destroy ability of coiled material; Rigidity is big, and prefabricated typing can overcome the foaming of creasing under the waterproofing course high temperature, and low temperature shrinks down to be broken.
