Abstract

To reduce the fire hazard of acrylonitrile butadiene-styrene (ABS), the Sb₂MoO₆ (AM) nanosheets were successfully prepared by a simple hydrothermal method using SbCl₃ and NaMoO₄·2H₂O as Sb and Mo sources, respectively. At different loading levels (0–10 wt%), the Sb₂MoO₆ nanoflakes can be uniformly dispersed in the ABS matrix. Compared with pure ABS, the tensile strength of ABS/AM10 composite with 10 wt% of AM increased by 13%, indicative of the reinforcement effect of AM. Moreover, the introduction of AM did not reduce the initial decomposition temperature of ABS composites, but significantly increased the residue at 600 °C, demonstrating the improved carbonization. AM effectively improved the fire safety of ABS, and 5 and 10 wt% of it decreased the peak heat release rate (PHRR) of ABS/AM5 and ABS/AM10 by 19.7% and 32.9%, respectively. The peak smoke production rate (PSPR) of ABS/AM10 was reduced by 32.4% relative to that of ABS. The improved fire safety of ABS/AM composites was mainly attributed to the physical barrier effect of Sb₂MoO₆ nanosheets. Therefore, this work proposes a feasible approach for the preparation of fire-retardant and strong ABS composites based on metal-oxide nanomaterials.

合成多功能 Sb2MoO6 纳米片，提高 ABS 树脂的防火安全性和机械强度

为了降低丙烯腈-丁二烯-苯乙烯（ABS）的火灾危险性，研究人员分别以 SbCl3 和 NaMoO4-2H2O 为 Sb 和 Mo 源，通过简单的水热法成功制备了 Sb2MoO6（AM）纳米片。在不同的负载水平（0-10 wt%）下，Sb2MoO6 纳米片都能均匀地分散在 ABS 基体中。与纯 ABS 相比，含有 10 wt% AM 的 ABS/AM10 复合材料的拉伸强度提高了 13%，这表明 AM 具有增强作用。此外，AM 的引入并没有降低 ABS 复合材料的初始分解温度，但却显著提高了 600 °C 时的残余物，这表明了碳化效果的改善。AM有效提高了ABS的防火安全性，5 wt%和10 wt%的AM使ABS/AM5和ABS/AM10的峰值热释放率（PRR）分别降低了19.7%和32.9%。与 ABS 相比，ABS/AM10 的峰值产烟率 (PSPR) 降低了 32.4%。ABS/AM 复合材料防火安全性的提高主要归功于 Sb2MoO6 纳米片的物理阻隔效应。因此，本研究提出了一种基于金属氧化物纳米材料制备阻燃性强的 ABS 复合材料的可行方法。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
