Abstract
It has always been the goal of flame retardant research to improve the flame retardancy of a polymer efficiently without compromising comprehensive properties such as mechanical properties. For polyvinyl alcohol (PVA), inspired by the multiple hydrogen bonding in spider silk, we design a new type of compound containing phosphorus and nitrogen with multiple hydrogen-bonding reaction sites (N,N',N''-tris(2-aminoethyl)phosphoric triamide (TE)) as it is flame retardant. The dynamic cross-linking structure is constructed, and the hyperdispersion of flame retardancy is achieved by the hydrogen bond self-assembly between TE and PVA, thus the high-performance flame retardant PVA is obtained. With only a 10 wt % addition of TE, the PVA film with a thickness of 0.15 mm can reach the UL94 VTM-0 level, and its tensile strength, ductility, and initial decomposition temperature can be increased by 33, 15, and 12 °C, respectively. In addition, the hydrogen-bonding effect and flame retardant mechanism are characterized and studied. This work overcomes the shortcomings of traditional flame retarding approaches and provides an effective strategy for the preparation of flame retardant polymers with an excellent performance.

[PMID: 32694665 PMCID: PMC7374163 DOI: 10.1038/s41598-020-68910-6] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 07/03/2020] [Indexed: 12/03/2022] Open
Abstract
A novel eco-friendly halogen-free cardanol-based flame retardant with P, Si, and N on the chain backbone (PSNCFR) was synthesized and incorporated into phenolic foams (PFs). PSNCFR was comprehensively investigated via Fourier transform infrared spectroscopy and nuclear magnetic resonance. PSNCFR endowed PFs with flame retardancy, contributed to generating a composite char defense against flames, and efficiently prevented smoking from PFs. PSNCFR introduction improved the flexural strength of the PFs to approximately 155% of that of pristine PF. PSNCFR-modified PFs displayed a high limiting oxygen index value of 41.9%. The results of cone calorimeter show that the mean heat release rate, mean effective heat of combustion, and total heat release of the PSNCFR-modified PFs reduced by 26.92%, 35.71%, and 31.25%, respectively. In particular, the total smoke production of the PSNCFR-modified PFs decreased by 64.55%, indicating excellent smoke inhibition. As for the mechanism, the condensation and gas phases during pyrolysis were responsible for the synergistic flame retardancy in the modified PFs. The findings demonstrate that PSNCFR can be used in PF preparation to overcome their drawbacks of internal brittleness and flammability.
