Description
Technical Field
The utility model relates to a building waterproof material technical field, especially a spread TPO waterproofing membrane in advance.
Background
The overlapping of coiled material usually adopts hot air welding or self-adhesive tape overlapping when it lays to pave TPO waterproofing membrane of the commonly used preliminary laying of underground construction waterproofing engineering at present.
During hot air welding, the lap joint strength of the coiled materials is good, but the defects are obvious, namely the construction speed is low, so that the construction period is long; moreover, welding has higher requirements on the skills of constructors, and the occurrence frequency of the phenomena of missing welding and insufficient welding in the construction process is higher. When the self-adhesive tape is used for lapping, due to the non-polarity of TPO, the common lapping can not achieve a good bonding effect.
Disclosure of Invention
The utility model aims at overcoming the defect of above-mentioned prior art, provide a construction comparatively convenient, a higher TPO waterproofing membrane of shop in advance of overlap joint intensity.
The utility model discloses can realize through following technical scheme: the utility model provides a pre-paved TPO waterproofing membrane, includes from last to the viscidity layer, butyl rubber self-adhesive layer, TPO matrix layer that stack set up down, its characterized in that: a front-face butyl rubber self-adhesive layer overlapping edge with the width of L is reserved on one side edge of the upper surface anti-adhesive layer of the butyl rubber self-adhesive layer in the width direction, and a front-face overlapping edge isolation film is arranged on the overlapping edge of the front-face butyl rubber self-adhesive layer; the bottom surface of the TPO carcass layer on the other side opposite to the overlapping edge of the front butyl rubber self-adhesive layer in the width direction is provided with a back butyl rubber self-adhesive overlapping layer with the width of L, and a back overlapping edge isolating membrane is arranged on the lower surface of the back butyl rubber self-adhesive overlapping layer.
The anti-sticking layer is quartz sand which is subjected to coupling post-treatment by a silane coupling agent, and the fineness of the anti-sticking layer is 50-80 meshes.
The width L of the front butyl rubber self-adhesive lap edge and the back butyl rubber self-adhesive lap layer is 50-100 mm.
The utility model relates to a spreading TPO waterproofing membrane's overlap joint mode in advance is the self-adhesion overlap joint, through spreading TPO waterproofing membrane in advance at the positive butyl rubber self-adhesion overlap joint limit overlap joint of each other that sets up with the back of width direction, distinguishes in traditional TPO waterproofing membrane's hot-blast welding and the overlap joint mode of sticky tape mutually, adopts the utility model discloses a self-adhesion overlap joint is more firm than traditional sticky tape overlap joint, and is more convenient than hot-blast welding construction.

Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The invention will be described in more detail with reference to the accompanying drawings:
as shown in fig. 1, the pre-paved TPO waterproof roll comprises an anti-adhesion layer 1, a butyl rubber self-adhesive layer 2 and a TPO carcass layer 3 which are stacked from top to bottom, wherein a front butyl rubber self-adhesive layer overlapping edge with a width of L is reserved on one side edge of the anti-adhesion layer 1 on the upper surface of the butyl rubber self-adhesive layer 2 in the width direction, and a front overlapping edge isolation film 6 is arranged on the front butyl rubber self-adhesive layer overlapping edge; the bottom surface of the TPO carcass layer 3 on the other side opposite to the overlapping edge of the front butyl rubber self-adhesive layer in the width direction is provided with a back butyl rubber self-adhesive overlapping layer 4 with the width of L, and a back overlapping edge isolating membrane 5 is arranged on the lower surface of the back butyl rubber self-adhesive overlapping layer 4.
The anti-sticking layer 1 adopts common quartz sand which is coupled and post-treated by a silane coupling agent, and the fineness of the common quartz sand is 50-80 meshes. The arrangement of the anti-adhesion layer is to avoid the stickiness of the butyl rubber self-adhesion layer to the shoes when the constructor walks back and forth.
The width L of the front butyl rubber self-adhesive overlapping edge and the back butyl rubber self-adhesive overlapping layer 4 is 50-100mm, and the width L adopted in the embodiment is 80 mm. The utility model discloses butyl rubber self-adhesive layer material in the pre-paved TPO waterproofing membrane adopts raw materials such as butyl rubber, tackifying resin, plasticizer, filler, viscosity modifier, vulcanizing agent, antiager to make.
Figure 2 shows, when specifically paving and pasting, will the utility model discloses spread TPO waterproofing membrane in advance and paste at the concrete basal plane, with two coiled material overlap joint completion backs of each other, at first tear positive overlap joint limit barrier 6, then tear back overlap joint limit barrier 5, laminate two self-adhesive layer overlap joint limits, can accomplish the overlap joint of coiled material.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
