Abstract
The utility model provides a thermoplastic polyurethane modified polyvinyl chloride self-adhesion waterproof roll material which sequentially comprises an anti-ageing layer, a polyvinyl chloride waterproof layer, a blocking layer, a rubber modified asphalt self-adhesion layer and an isolation layer, wherein the anti-ageing layer refers to a thermoplastic polyurethane resin modified polyvinyl chloride layer and is not less than 0.4mm in thickness. The roll material is not less than 1.8mm in overall thickness. Compared with the prior art, the roll material has the advantages and the positive effects that as the anti-ageing layer is arranged and the advantages of excellent anti-ageing performance, high strength, high extension and the like of thermoplastic polyurethane are fully utilized, the problem of volatile migration of a plasticizer is solved when the roll material is applied to a one-layer roofing project; due to the blocking layer between the polyvinyl chloride waterproof layer and the rubber modified asphalt self-adhesion layer, the problem of seepage of oil of the rubber modified asphalt self-adhesion layer into the polyvinyl chloride waterproof layer is solved, and the service life of the roll material is prolonged.
Description
Technical field
The utility model belongs to waterproof roll technical field, especially relates to a kind of thermoplastic polyurethane modified polyvinyl chloride adhesive waterproof coil.
Background technology
Polyvinyl chloride adhesive waterproof coil is that the self-adhesive rubber asphalt that the synthetic rubber such as a kind of SBS of take, tackifier and high-quality asphalt etc. are mixed with is base-material, ageing-resistant polyvinyl chloride is as top surface, and strippable painting silicon barrier film or painting silicon barrier paper are the waterproof material that the antiseized isolated material of lower surface is made.
In existing technology, polyvinyl chloride adhesive waterproof coil generally comprises separation layer, polyvinyl chloride layer, rubber modified asphalt self-adhesive layer and separation layer.Because being all adopts dioctyl ester (DOP) to make plasticizer, when single-layer roof is used, due to plasticizer volatilization migration, can make polyvinyl chloride adhesive waterproof coil season cracking, bring harm to the safety of watertight composition; The oil content of rubber modified asphalt self-adhesive layer is to polyvinyl chloride watertight composition infiltration problem.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of thermoplastic polyurethane modified polyvinyl chloride adhesive waterproof coil, is particularly useful for single-layer roof waterproof and uses.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Thermoplastic polyurethane modified polyvinyl chloride adhesive waterproof coil, comprises anti-aging layer, polyvinyl chloride watertight composition, barrier layer, rubber modified asphalt self-adhesive layer and separation layer successively.
Further, described anti-aging layer is TPU modified polyvinyl chloride layer.
Further, the thickness of described anti-aging layer is not less than 0.4 millimeter, and the integral thickness of described coiled material is not less than 1.8 millimeters.
Further, described barrier layer consists of seven-layer co-extrusion high-isolating film.
Further, described rubber modified asphalt self-adhesive layer is rubber modified asphalt layer.
Advantage and the good effect that the utlity model has are: compared with prior art, because the utility model is provided with anti-aging layer, make full use of the advantages such as the ageing-resistant performance, high strength of thermoplastic polyurethane excellence, high extension, while making coiled material be applied to single-layer roof engineering, solved the problem of plasticizer volatilization migration, between polyvinyl chloride watertight composition and rubber modified asphalt self-adhesive layer, be provided with oil content that barrier layer solved rubber modified asphalt self-adhesive layer to polyvinyl chloride watertight composition infiltration problem simultaneously, extended the service life of coiled material.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, anti-aging layer 2, polyvinyl chloride watertight composition 3, barrier layer
4, rubber modified asphalt self-adhesive layer 5, separation layer
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of thermoplastic polyurethane modified polyvinyl chloride adhesive waterproof coil is layer structure, comprise successively anti-aging layer 1, polyvinyl chloride watertight composition 2, barrier layer 3, rubber modified asphalt self-adhesive layer 4 and separation layer 5, the integral thickness of described coiled material is not less than 1.8 millimeters;
Described anti-aging layer is TPU modified polyvinyl chloride layer, through plastic extrusion, calendering technology, processes, and its thickness is not less than 0.4 millimeter, has the performances such as excellent ageing-resistant performance, percentage elongation is large, tensile strength is high;
Described polyvinyl chloride watertight composition 2 is processed through plastic extrusion, calendering technology by Corvic;
Described barrier layer 3 consists of seven-layer co-extrusion high-isolating film;
Described rubber modified asphalt self-adhesive layer 4 is rubber modified asphalt layer, by SBS modified pitch, adds the auxiliary agents such as binder resin to process.
Described separation layer 5 is by polyethylene silicon oil lamella.
The utility model thermoplastic polyurethane modified polyvinyl chloride adhesive waterproof coil is mainly used in the waterproofing works such as hydraulic engineering, roofing, side wall, basement, makes waterproof purposes.During use, separation layer 5 is taken off, rubber modified asphalt self-adhesive layer 4 is laid in polymer cement Binder Materials, rubber modified asphalt self-adhesive layer can form mutual string network structure with polymer cement Binder Materials, finally forms continuous mechanical adhesion.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
