“…In recent years, zinc hydroxystannate (ZHS) has attracted growing attention owing to significantly improving flame retardancy of poly (vinyl chloride) (PVC). Compared with other inorganic flame retardants, ZHS have outstanding properties, such as low addition, low toxicity, and high efficiency, and will become a useful replacement of the conventional inorganic fillers [ 15 – 17 ]. Unfortunately, ZHS as flame retardant is less competitive in terms of cost and has a poor compatibility like other inorganic fillers in PVC bringing about the deterioration of mechanical properties, which is undesirable for the fabrication of high-performance materials.…”

A novel flame retardant, zinc hydroxystannate-decorated graphene oxide (ZHS/GO) nanohybrid, was successfully prepared and well characterized. Herein, the ZHS nanoparticles could not only enhance the flame retardancy of GO with the synergistic flame-retardant effect of ZHS but also prevent the restack of GO to improve the mechanical properties of poly (vinyl chloride) (PVC) matrix. The structure characterization showed ZHS nanoparticles were bonded onto the surface of GO nanosheets and the ZHS nanoparticles were well distributed on the surface of GO. Subsequently, resulting ZHS/GO was introduced into flexible PVC and fire hazards and mechanical properties of PVC nanocomposites were investigated. Compared to neat PVC, thermogravimetric analysis exhibited that the addition of ZHS/GO into PVC matrix led to an improvement of the charring amount and thermal stability of char residue. Moreover, the incorporation of 5 wt.% ZHS/GO imparted excellent flame retardancy to flexible PVC, as shown by increased limiting oxygen index, reduced peak heat release rate, and total heat release tested by an oxygen index meter and a cone calorimeter, respectively. In addition, the addition of ZHS/GO nanohybrids decreased the smoke products and increased the tensile strength of PVC. Above-excellent flame-retardant properties are generally attributed to the synergistic effect of GO and ZHS, containing good dispersion of ZHS/GO in PVC matrix, the physical barrier of GO, and the catalytic char function of ZHS.

“…The intumescent char with a higher degree of graphitization can prevent the heat and mass transfer between the combustion zone and the condensed phase, leading to a great decrease in pHRR, THR and TSR 54 . Besides, the tin compounds (ie, tin phosphate) in the char residue of EP/TETP composites proved by XRD may have smoke suppressive ability for EP 55,56 . Therefore, TETP exhibits good flame‐retardant and smoke suppressive efficiency in EP.…”

A nitrogen-containing metal-organic phosphonate, that is, tin ethylenediamine tetramethylene phosphonate (TETP) was synthesized, characterized, and then used as the flame-retardant additive in epoxy resin (EP). The flame retardancy, smoke suppression, thermal stability, and mechanical performances of the EP/TETP composites were thoroughly evaluated. It is found that the EP composite with 7.0 wt% of TETP (EP/TETP-7) can pass UL-94 V-0 rating with a high LOI value of 29.5%. Cone calorimeter results show that the peak heat release rate, total heat release, and total smoke release of EP/TETP-7 are decreased by 45.7%, 27.3%, and 37.3%, respectively, compared with pure EP. Besides, the production rates of CO and CO 2 of EP/TETP-7 are reduced remarkably. Thermogravimetric analysis results indicate that the char residue of EP/TETP-7 at 800 C is almost double than that of pure EP. Moreover, the incorporation of TETP has less influence on the mechanical performances and thermal resistance (ie, glass transition temperature) of EP/TETP composites.

“…Recently, they investigated the flame retardant properties of PVC treated with two different morphologies of CaCO 3 coated by ZHS. [ 46 ] The PVC treated with ZHS‐coated dendritic fibrillar CaCO 3 had almost the same LOI value as that of the PVC treated with ZHS‐coated cubic CaCO 3 under the same loading amount. Higher ZHS content was beneficial for improving the flame retardant effects of the hybrid, but produced more smoke.…”

As a versatile star product, poly(vinyl chloride) (PVC) has kept active in our daily life all through since it was invented. However, the severe fire hazard and heavy smoke produced during combustion, particularly the extensively used flexible PVC products, have been puzzling manufacturers and researchers for ages. Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced. Meanwhile, the flame retardant mechanisms and experimental analysis results are described to understand the relationship between characters of flame retardants (including chemical compositions, structures or morphologies) and fire performance of the composites. The potential substitutes for traditional harmful flame retardant antimony trioxide are discussed aiming to the emphasis on increasing prominent environmental concerns. In particular, one section is dedicated to new approaches for the preparation of novel environmentally friendly and high-efficiency flame retardants. It is hoped that this review will not only summarize the new emerged flame retardants and smoke suppressants for PVC, but also provide the new trend to prompt sequent exploration in both academic research and industrial application.
