Problems solved by technology

[0004] EPDM waterproofing membrane has excellent electrical insulation performance, and the charge is easy to accumulate to generate static electricity accumulation, causing dust suction, electric shock, and even sparks to cause vicious accidents such as burning, threatening the safety of people's lives and property. It is used in industrial and civil buildings. Causes certain hazards, which seriously restricts its application in chemical industry, oil refining, mine and other fields
[0005] EPDM waterproofing membranes mainly use base treatment agents, base adhesives, membrane seam adhesives and sealants during waterproof construction. Since EPDM rubber itself is an inert material, its polarity is extremely poor. The bonding effect with the adhesive is poor, and long-term use is prone to delamination, resulting in water leakage or micro-leakage, which seriously restricts the development of EPDM waterproofing membranes in the market, and has become an impact on EPDM waterproofing. The main problem of the use of coil
[0006] As a weather-resistant material, EPDM waterproofing membrane is recognized by the people, but at present, functional EPDM waterproofing membranes are mostly focused on flame retardancy, but the performance and combustion of waterproofing membranes in long-term use The cause is less concerned, poor wear resistance, poor antistatic ability in complex and harsh environments; short service life; general flame retardancy; Long-term use is easy to fall off with the glue, the strength and extensibility are average; the retention rate of tensile strength and elongation at break are poor;
[0007] The preparation method of existing EPDM waterproofing membrane is complex, high energy consumption, and not environmentally friendly
[0008] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
