Abstract

The widespread use of polymeric materials in various industries and fields of activity is explained by the thermal stability of polymers, their high strength characteristics, and the durability and reliability of synthetic materials. The introduction of additives can change the physical-mechanical, thermophysical, optical, electrical, frictional and other performance characteristics of the original (base) polymer. The purpose of the article is to investigate the safety of using isophthalic acid filler in a polymer composition. Methodology. Application of theoretical research methods, regulatory documents. Results. The spheres of polymeric materials application are considered. Ways of creating polymers with specified properties by introducing fillers into their composition, which change not only the operational characteristics, but also the physical and chemical characteristics of the original polymer are investigated. In view of the identification for danger of using isophthalic acid as a filler for phenylone, its physicochemical composition, stability, reactivity, toxicity, and environmental impact are studied. The measures and means of ensuring fire and explosion safety, means of controlling hazardous exposure, precautionary measures for personnel and personal protective equipment when working with isophthalic acid are considered. As a result of the research, it is possible to obtain an optimal polymer composition with improved plastic characteristics and safe properties. Scientific novelty. The possibility of obtaining an optimal polymer composition is shown: with improved plastic characteristics due to the addition of the biodegradable isophthalic acid filler fenilon to the polymer material; safe properties for humans and the environment, namely the absence of toxic substances release under the influence of heat, light and other external actions. Practical value. The resulting polycomposite material with updated plastic characteristics and safety properties can be used for further processing of secondary polymer raw materials.

二苯二甲酸作为高分子材料成分的安全性
聚合物材料在各种工业和活动领域的广泛应用是由聚合物的热稳定性、高强度特性以及合成材料的耐久性和可靠性来解释的。添加剂的引入可以改变原(基)聚合物的物理-机械、热物理、光学、电学、摩擦等性能特征。本文的目的是研究在聚合物组合物中使用间苯二甲酸填料的安全性。方法。应用理论研究方法,规范性文件。结果。讨论了高分子材料的应用领域。研究了通过在聚合物的组成中引入填料来制造具有特定性能的聚合物的方法,这些填料不仅改变了聚合物的操作特性,而且改变了原聚合物的物理和化学特性。针对苯并苯二甲酸作为苯的填料的危险性鉴定,对苯并苯二苯甲酸的理化成分、稳定性、反应性、毒性和环境影响进行了研究。考虑了在使用间苯二甲酸时确保火灾和爆炸安全的措施和手段、控制危险暴露的手段、人员和个人防护设备的预防措施。作为研究的结果,有可能获得具有改进的塑料特性和安全性能的最佳聚合物组合物。科学的新奇。所示为获得最佳聚合物组合物的可能性:由于在所述聚合物材料中添加了可生物降解的间苯二甲酸填料fenilon,因而具有改善的塑性特性;对人类和环境的安全性能,即在热、光和其他外界作用的影响下不释放有毒物质。实用价值。所得的复合材料具有更新的塑性特性和安全性能,可用于二次聚合物原料的进一步加工。
