Description
Technical field
The present invention relates to a kind of polymer membranes, more particularly, to a kind of roofing thermoplastic polyolefin TPO waterproofs
Coiled material and preparation method thereof belongs to waterproof chemistry Material Field.
Background technology
It is also increasing to the waterproof material demand of architectural engineering with the raising of present Building technology, quality is wanted
Ask also higher and higher, therefore the popularizing application prospect of novel high polymer waterproof roll is also more and more wide.Macromolecule waterproof is rolled up
Material is a kind of new construction material, its high-strength light, the multi-functional development trend for meeting building materials innovation of low energy consumption, common product
Kind has PVC waterproof rolls, EPDM waterproof rolls, CPE waterproof rolls and TPO waterproof rolls.In current waterproof material
In, more mature is exactly PVC waterproof roll, and PVC waterproof roll relative price is cheap, can be welded with body,
But there is the plasticizer extravasation technical barrier easy to migrate inside PVC waterproof roll, can not fundamentally solve,
Its using effect is eventually reduced, the scope of application is also greatly restricted.And TPO waterproof rolls are the height of latest development
Molecule class waterproof roll, it is to add the new of other auxiliary agents preparations as base-material using Petropols and ethylene, acetic acid, vinyl
Waterproof roll combines the weldability of the weatherabilities of EPDM coiled materials, low-temperature tenderness and PVC coiled materials, it has also become individual layer room
One of main material of plane system.
It is as follows to retrieve the document in relation to thermoplastic polyolefin TPO waterproof rolls：
