Problems solved by technology

But for waterproofing membranes used in construction, we blindly pay attention to its "waterproofness", but often ignore its "fire resistance" and "heat insulation", which also caused safety incidents.
The fire at CCTV’s new site in 2009 was caused by the burning anti-aircraft gun fireworks falling on the flammable EPDM waterproofing membrane on the roof, which ignited the insulation material, which triggered the fire and caused an economic loss of 600-700 million
[0005] At present, the main problems in PBT coils are: (1) poor flame retardancy, easy to cause fire, and poor safety; (2) low tensile strength and elongation at break; (3) weak performance against external tearing ; (4) easy aging, short service life

Description

technical field [0001] The invention relates to a plastic film manufacturing technology, in particular to a PBT coil and a production process thereof. Background technique [0002] Safety and waterproofing have always been two important issues in building waterproofing. The development and application scale of waterproofing materials can represent a country and region's emphasis on building safety in some respects. With the vigorous development of my country's construction industry, the use of waterproof membranes for construction has increased significantly year by year. But for waterproofing membranes used in construction, we blindly pay attention to its "waterproofness", but often ignore its "fire resistance" and "heat insulation", which also caused safety incidents. The fire at CCTV’s new site in 2009 was caused by the burning anti-aircraft gun fireworks falling on the flammable EPDM waterproof membrane on the roof, which ignited the insulation material, which triggered...
