Description

Technical Field

[0001] The utility model relates to the field of waterproof coiled materials, in particular to a novel TPO composite waterproof coiled material. Background Art

[0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist the leakage of external rainwater and groundwater. It is a kind of flexible building material product that can be rolled into a roll. As a leak-free connection between the engineering foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project. Existing waterproof membranes such as the publication number CN219670419U, a kind of internal composite TPO / PVC maintenance special self-adhesive waterproof membrane, are composed of a first polymer sheet, a glass fiber non-woven composite layer, a second polymer sheet, a PP+PET non-woven composite layer, and a PVC self-adhesive waterproof membrane. The PP+PET non-woven composite layer is provided at the bottom of the second polymer sheet layer, the self-adhesive layer is self-adhesive to the bottom of the PP+PET non-woven composite layer, and the bottom of the self-adhesive layer is provided with an anti-adhesive isolation layer; the first polymer sheet layer and the second polymer sheet layer are both made of PVC or TPO material, the glass fiber non-woven composite layer is made of glass fiber non-woven fabric, the PP+PET non-woven composite layer is made of PP+PET non-woven fabric, the self-adhesive layer is made of thick butyl rubber, and the anti-adhesive isolation layer is an anti-adhesive isolation film.

[0003] During the production of the above-mentioned waterproof membrane, the first polymer sheet layer, the glass fiber non-woven composite layer, the second polymer sheet layer and the PP+PET non-woven composite layer are stacked and composited together layer by layer. However, during use, openings are inevitable at the joints between the first polymer sheet layer, the glass fiber non-woven composite layer, the second polymer sheet layer and the PP+PET non-woven composite layer. For this reason, we propose a new type of TPO composite waterproof membrane. Utility Model Content

[0004] The purpose of the utility model is to provide a new type of TPO composite waterproof membrane, including a composite layer component, the outer side of the composite layer component is fixedly wrapped with a thermally aspirated polyolefin sheet, the top of the thermally aspirated polyolefin sheet is evenly provided with multiple groups of protrusions, the bottom of the thermally aspirated polyolefin sheet is bonded with a polymer adhesive, and the bottom of the polymer adhesive is provided with a granular anti-sticking layer.

[0005] Preferably, the composite layer assembly includes a polymer sheet layer 1, a glass fiber non-woven composite layer, and a polymer sheet layer 2. The polymer sheet layer 1 is laid on the top of the glass fiber non-woven composite layer, and the polymer sheet layer 2 is laid on the bottom of the glass fiber non-woven composite layer.

[0006] Preferably: the top of the polymer layer 1 is fixedly connected to the thermally desirable polyolefin sheet, the bottom of the polymer layer 2 is fixedly connected to the thermally desirable polyolefin sheet, both sides of the polymer layer 1 are fixedly connected to the thermally desirable polyolefin sheet, both sides of the glass fiber non-woven composite layer are fixedly connected to the thermally desirable polyolefin sheet, and both sides of the polymer layer 2 are fixedly connected to the thermally desirable polyolefin sheet.

[0007] Preferably, the two ends of the thermally aspirating polyolefin sheet are in contact with each other and are fixedly connected to each other.

[0008] Preferably, the bottom of the thermally desirable polyolefin sheet is provided with a plurality of recessed portions, and the tops of the polymer adhesives are all pushed into the inner cavities of the recessed portions.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. During the production of the present invention, the composite layer assembly is wrapped by the thermally aspirated polyolefin sheet, so that the thermally aspirated polyolefin sheet can stably wrap the polymer layer 1, the glass fiber non-woven composite layer, and the polymer layer 2, thereby preventing the connections between the polymer layer 1, the glass fiber non-woven composite layer, and the polymer layer 2 from being exposed to the outside, thereby preventing the connections between the polymer layer 1, the glass fiber non-woven composite layer, and the polymer layer 2 from being easily opened.

[0011] 2. It is made of thermally resistant polyolefin sheets and synthetic polymer adhesives, with excellent properties such as high tensile strength, large elongation, impact resistance, tear resistance, chemical corrosion resistance, thermal aging dimensional stability, etc.; excellent chemical corrosion resistance: acid, alkali, salt corrosion, and resistance to the growth of microorganisms such as algae and mold.

[0012] 3. Through the multiple groups of recessed parts at the bottom of the thermally aspirated polyolefin sheet, the top of the polymer adhesive is pushed into the inner cavity of the recessed parts, thereby expanding the contact range between the thermally aspirated polyolefin sheet and the polymer adhesive, thereby making the bonding between the thermally aspirated polyolefin sheet and the polymer adhesive more secure;

[0013] 4. When in use, the pre-laid reverse-adhesive method is adopted for construction, which can be integrated with the self-waterproofing of the concrete structure. The polymer adhesive (polymer adhesive is the polymer self-adhesive film) and the uninitialized cement slurry in the post-cast concrete creep under pressure and penetrate the anti-adhesive layer in opposite directions, forming effective interpenetrating bonding and huge intermolecular forces. After the concrete solidifies, the gap between the polymer self-adhesive film waterproofing membrane and the main structure is sealed to the maximum extent, eliminating the water leakage channel.
