Description

Pre-paved TPO waterproof coiled material

Technical Field

The utility model belongs to the technical field of waterproofing membrane.

Background

The pre-laid waterproof roll material commonly used in the current underground building waterproof engineering is constructed into a sand grain anti-sticking protective layer, a self-sticking layer and a sheet layer. When the coiled material is laid, the sand surface of the coiled material faces upwards, and a bonding effect is formed after the sand anti-adhesion protective layer and the self-adhesion layer and the concrete of the post-poured main structure are subjected to chemical reaction, so that the water channeling prevention effect is generated on the water resistance of the main structure due to the bonding effect. And only the empty pavement is needed between the coiled material and the concrete cushion layer, and the bonding procedure of the traditional asphalt coiled material and the cushion layer is not needed, so that the construction period is shortened, and the cost is saved.

However, the production difficulty of the pre-laid waterproof roll material relying on the chemical reaction is high, and the rubber mixing and gluing processes in the production process generate smoke which is not environment-friendly, so that the production method is not in accordance with the high requirements of people on environment protection. The sand is adopted as the structure of the viscosity-reducing protective layer, the sand needs to be coupled in advance, the coupling process is carried out at high temperature and high pressure, the high-risk operation process belongs to, and a large amount of smoke is generated in the production process, which is not in accordance with the current higher requirements of people on environmental protection.

The traditional pre-laid waterproof roll has high self weight due to sand grains on the surface, the self weight of the roll per square meter is 2.2-2.4 kg/m2, and for a roll of pre-laid roll with the width of 2m and the length of 20m, the weight of a single roll reaches 88-96 kg, so that high long-distance transportation cost and difficulty are caused, and great difficulty is caused in the secondary carrying process of workers on site.

The self-adhesive generates a rapid aging phenomenon under the exposure of natural light when the pre-laid waterproof roll relying on chemical reaction is in a state of on-site shutdown in the use process. The ultraviolet ageing time for the self-adhesive in the new standard GB23457-2017 of pre-laid waterproof rolls is 7 days, namely 196 hours, and the downtime of a construction site can far exceed the time. The aging of the self-adhesive of the coil may cause the reaction bonding effect of the coil and the main concrete to be poor or even failure.

SUMMERY OF THE UTILITY MODEL

The invention provides a pre-paved TPO waterproof coiled material to solve the technical problems.

The utility model provides a technical scheme that above-mentioned technical problem took is: the utility model provides a spread TPO waterproofing membrane in advance, its structural feature lies in: from top to bottom is equipped with upper surface interlock layer and TPO matrix layer in proper order, and upper surface interlock layer and TPO matrix layer hot pressing composite connection shaping, the thorn hair in the upper surface interlock layer is the magic subsides, and the magic subsides have the one side of thorn hair up, and thorn hair matter is hard, has crooked and hook.

Preferably, the bristles are made of nylon.

Preferably, the TPO carcass layer is made of thermoplastic polyolefin.

Further, the width of the upper surface occlusal layer is the width of the TPO carcass layer minus the width L of the lap joint edge.

Further, the width L of the overlapping edge is 80 mm.

The utility model has the advantages that: the utility model adopts the bending and hook of the bur in the magic tape and the post-pouring concrete to form mechanical engaging force, which can complete the pre-spreading anti-sticking effect of the pre-spread coiled material and the post-pouring concrete, the bur is made of nylon material, is not easy to burn, has no pungent smell, and meets the requirements of energy saving and environmental protection; because the weight of the bristles made of the nylon material is light, the weight of the pre-laid waterproof roll is reduced, and the transportation and the carrying are convenient; the bending and hook that thorn hair in the magic subsides had form mechanical interlock with post-cast concrete, and this kind of bonding structure has abandoned the natural glue that relies on chemical reaction's formula waterproofing membrane to adopt of pre-spread, has solved the ageing of coiled material self-adhesive and may lead to the relatively poor or even inefficacy problem of reaction bonding effect of coiled material and main part concrete.
