Abstract: In this work, a type of fireresistant coiled materials used as for steel structure protection was prepared by using lowdensity polyethylene (PE-LD), ethylenepropylenedienemonomer rubber (EPDM) and chlorinated polyethylene (CPE) as base materials. The influence of base materials on the performance of fireresistant coiled materials was investigated. The results indicated that the fireresistant coiled materials achieved better fire resistance, higher tensile strength and greater elongation at break when CPE was used as a base material, whereas they exhibited lower flexural strength and modulus when EPDM was used as a base material. When a compound of CPE and EPDM was used as base materials at a weight ratio of 6:4, the fireresistant coiled materials not only gained an expansion ratio of 22 and good fire resistance but also achieved much better mechanical properties in terms of tensile strength of 2.31 MPa, elongation at break of 855.47 %, flexural strength of 5.47 MPa and flexural modulus of 6.11 MPa. It is concluded that the compound of CPE and EPDM was more suitable as a based material for preparation of the fireresistant coiled materials due to the advantage of intumescent flame retardancy.
Key words: fire-resistant coiled materials for steel structure protection, ethylene-propylene-diene monomer rubber, chlorinated polyethylene, fire-resistant performance, low-density polyethylene
