Abstract

The presented study was focused on the development of a sustainable type of composite characterized by improved flame retardance. Polyamide 6 (PA6) was modified with the addition of biocarbon (BC) and organic phosphorous flame retardant (OP). The initial part of the study was aimed at the evaluation of the OP:BC system efficiency, while the final part of the research focuses on the preparation of composites with basalt fibers (BF) reinforcement. Composite materials were modified using 20% of the OP:BC mixture at different ratios. The reinforced samples were modified with an additional 20% of the BF filler. Prepared samples were subjected to detailed analysis, mechanical properties evaluation, thermal analysis, microscopic observations, and burning tests. The results indicate that the application of the developed concept led to a large decrease in flammability for most of the investigated PA6-based materials; however, the most interesting results refer to materials containing a balanced OP:BC system.

开发一种新型可持续阻燃聚酰胺 6（PA6）基复合材料，并用生物碳/磷阻燃剂/盐纤维体系（BC/OP/BF）进行改性。材料性能和可燃性评估

本研究的重点是开发一种可持续的复合材料，其特点是阻燃性能得到改善。通过添加生物碳（BC）和有机磷阻燃剂（OP）对聚酰胺 6（PA6）进行改性。研究的最初部分旨在评估 OP:BC 系统的效率，而研究的最后部分则侧重于使用玄武岩纤维 (BF) 增强复合材料的制备。使用 20% 的 OP:BC 混合物以不同比例对复合材料进行改性。增强样品则使用额外 20% 的玄武岩纤维填料进行改性。对制备的样品进行了详细分析、机械性能评估、热分析、显微观察和燃烧试验。结果表明，应用所开发的概念可大大降低大部分 PA6 基材料的可燃性；不过，最有趣的结果是含有 OP:BC 平衡体系的材料。

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.
