Polyolefin TPO waterproof coil

Thermoplastic polyolefin (TPO) waterproof roll (TPO waterproof roll for short) is made of TPO resin based on the combination of weather resistance and heat resistance of ethylene propylene (EP) rubber and weldability of polypropylene. In the early 1990s, mechanical fixed pavement was applied to roof waterproof engineering. Because it has weather resistance of EPDM and weldability of plastic waterproof roll, it has reliable waterproof effect and outstanding aging resistance, so it develops rapidly. With its excellent physical and chemical properties and environmental protection properties, the coiled material has become the fastest growing waterproof material in the world. In the United States, TPO waterproof roll has accounted for 24% of the low slope commercial roofing material market in the United States, with an annual growth rate of more than 23%. In recent years, with the development of mechanical fixed single-layer roof system, high-performance TPO waterproof roll with energy-saving and environmental protection effect also has a rapid development momentum in China.

Products of various specifications are divided into

Reinforced TPO waterproof roll (H): thermoplastic polyolefin waterproof roll reinforced by polyester fabric in the middle of the roll.

Backing TPO waterproof roll (L): thermoplastic polyolefin waterproof roll with polyester non-woven fabric composite on the lower surface of the roll.

Homogeneous TPO waterproof roll (P): thermoplastic polyolefin waterproof roll without inner reinforcement or back lining.

Product characteristics

1. Advanced polymerization technology is adopted to combine EPDM with polypropylene, which has excellent weather resistance of EPDM and weldability of polypropylene.

2. Special formulation technology, no need to add any plasticizer which is easy to make the material brittle, no brittle phenomenon caused by the migration of plasticizer for general hot welding coil (such as PVC), and long-term waterproof function.

3. It has excellent high and low temperature resistance, and remains flexible with rubber like materials at a temperature of 50 ° C, and maintains mechanical strength at a high temperature.

4. Chemical resistance, acid, alkali, salt, animal oil, vegetable oil, lubricating oil corrosion resistance, algae, mold and other microbial growth resistance.

5. It has excellent root puncture resistant function and can be used as root puncture resistant coiled material of planting roof.

6. Heat resistant aging, good dimensional stability.

7. The light color surface, mainly white, has smooth surface, high reflectivity, energy saving effect and pollution resistance.

8. The components do not contain plasticizer and chlorinated polymer, and there is no harmful gas produced and released during welding and use, which is harmless to the environment and human health.

9. Hot welding construction is adopted for the joint, which can form a high-strength and reliable sealing waterproof layer.

10. Reinforced TPO waterproof roll is sandwiched with a layer of polyester fiber fabric in the middle; it provides high tensile property, high tear strength, fatigue resistance and puncture resistance of roll, which is more suitable for mechanical fixed roof system.

11. The fabric on the lower surface of the backing TPO waterproof coiled material makes the coiled material easier to bond with the base.

12. The homogeneous TPO waterproof roll has good plasticity and can be processed into various shapes after being heated to adapt to the practice of complex nodes.

Scope of application

It is mainly applicable to all kinds of roof waterproofing works such as industrial and civil buildings, public buildings, etc.

-H reinforced coiled material is suitable for roof waterproof system with mechanical fixing or air laying and coping;

-L-backing type coiled material is suitable for the waterproof system of the base full adhesion or empty paving and coping roof;

-P homogeneous waterproof roll is mainly used as flashing material.

Thermoplastic polyolefin (TPO) single layer roof system

TPO single-layer roof system refers to the roof system that uses single-layer TPO waterproof coiled material exposed for use, and uses mechanical fixation, full adhesion, air paving and coping method for construction.

I. TPO mechanical fixed single layer roof system

1. The TPO coil roofing system generally adopts mechanical fixation, that is, the reinforced TPO coil is laid empty on the base (or the fixed insulation board), in the adjacent lower layer coil joint area, the mechanical fastening screw and the fixed gasket are used to fix with the base, the upper layer coil covers the lower layer coil mechanical fastener, and the lap of the upper layer coil and the lower layer coil is welded by hot air, so that the coil is connected as a whole Sealed waterproof layer.

II. TPO full adhesive single layer roof system

The backing type TPO waterproof roll is fully adhered to the concrete or cement mortar base, and the adjacent TPO roll is welded with hot air to form an overall single-layer roof waterproof system.

III. TPO air paving and coping single layer roof system

The backing or reinforced waterproof coiled material shall be laid on the waterproof base empty, the adjacent TPO coiled material shall be welded with hot air, and the coiled material shall be paved with concrete blocks or pebbles

Roof waterproofing system.

Main supporting materials of the system

1. Homogeneous TPO prefabricated parts.

2. Base adhesive, cutting edge sealing, general sealing paste, coil cleaning agent.

3. Mechanical fixing screw, gasket, metal strip and load dispersion rope, etc

Key points of mechanical fixed single layer system construction

1. The thickness of the profiled steel plate as the base should be ≥ 0.75mm, and it must be reliably connected with the main structure. The connection between the steel plates should be smooth and continuous, without any sharp protrusion. The concrete base should be flat, dry, free of honeycomb, crack and other defects.

2. TPO coil pre laying: the coil shall be placed for 15-30 minutes after laying to fully release the internal stress of the coil and avoid wrinkling during welding.

3. Mechanical fixation of lower layer coil: the fixings shall be arranged in a straight and even way, and the spacing between fixings shall meet the design requirements. The fixings around the roof and in the corner area shall be provided with

MI.

4. Hot air welding: the upper coil covers the mechanical fastener of the lower coil, forming
