Description

Pre-paved reverse-adhesion type TPO waterproof coiled material with mechanical meshing effect

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 the sand anti-sticking protective layer and the self-adhesive layer and the concrete of the post-poured main structure are subjected to chemical reaction to form a bonding effect. Such a bonding effect causes a water channeling prevention effect on waterproofing of the main body structure. 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.

But the production difficulty of the pre-laid waterproof roll material relying on chemical reaction is larger, and the rubber mixing and gluing processes in the production process generate smoke which is not environment-friendly, which is not in accordance with the higher requirements of people on environment protection at present. 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 aging time for the self-adhesive in the new standard GB23457-2017 of Pre-paved waterproof coiled material is 7 days, namely 196 hours. And the downtime at the worksite may well exceed this 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.

For the traditional pre-paved waterproof coiled material which depends on quartz sand as an anti-sticking layer, the puncture resistance is usually lower, the puncture strength is usually 350N, and the falling and scratching of the steel bar on the common construction site are difficult to avoid. When the subsequent procedure construction of pre-laying coiled materials, namely steel bar binding, needs to adopt more coiled material protection measures, the protection cost of finished products is increased, and the construction period is prolonged.

SUMMERY OF THE UTILITY MODEL

The invention provides a pre-paved and anti-sticking TPO waterproof coiled material with a mechanical meshing effect, and aims to solve the technical problems.

The utility model provides a technical scheme that above-mentioned technical problem took is: the utility model provides a take machinery interlock effect pave in advance and turn over to glue type TPO waterproofing membrane, its structural feature lies in: the thorn wool sheet, the butyl self-adhesive layer and the TPO carcass layer are arranged from top to bottom in sequence; the side of the thorn wool sheet with the thorn wool faces upwards; the thorn hair piece, the butyl self-adhesive layer and the TPO carcass layer are formed by hot-pressing composite connection.
