Abstract

Polyvinyl chloride/calcium carbonate (PVC/CaCO₃) composites are widely used in the construction industry to fabricate flooring materials. However, PVC materials have raised concern due to the large quantity of plasticizers introduced during PVC product processing. Studies have reported that volatile organic chemicals (VOCs) are toxic with side effects on human health and the environment. Therefore, polypropylene (PP) is proposed as an alternative polymer for developing calcium carbonate-based polymer composite sheets for flooring applications with improved thermal, mechanical, and flammability properties. This work reviews the scientific and technological advances in the field of polypropylene/calcium carbonate–carbon nanomaterials or clay nanocomposites to develop a better understanding of how to develop superior nanocomposites for use in flooring applications. This work explores various studies about the synergistic effect of combining nanofillers (i.e., carbon nanomaterials or layered clays) with intumescent flame retardants and the synergist effect of nanofillers (i.e., multi-walled carbon nanotubes/montmorillonite) without intumescent flame retardants on thermal, mechanical, flammability properties, and morphologies of polypropylene. The generated information will facilitate the design of flooring materials based on PP with improved thermal, mechanical, and flammability properties. Therefore, it was confirmed that there is a relationship between the morphology (dispersion state of nanofillers in the PP), and mechanical properties, as well as the flammability of PP composites.

Highlights

The relationship between preparation, structure, property, and mechanisms
The synergism effect of inorganic flame retardants, multifunctionality, and flooring application
Challenges and future outlook on the development of PP/CaCO₃ /inorganic FR

聚氯乙烯/碳酸钙（PVC/CaCO3）复合材料在建筑业中被广泛用于制造地板材料。然而，由于在 PVC 产品加工过程中引入了大量增塑剂，PVC 材料引起了人们的关注。研究报告指出，挥发性有机化学物质（VOC）具有毒性，会对人类健康和环境产生副作用。因此，有人建议将聚丙烯（PP）作为一种替代聚合物，用于开发具有更好的热性能、机械性能和可燃性能的地板用碳酸钙基聚合物复合板材。本研究回顾了聚丙烯/碳酸钙-碳纳米材料或粘土纳米复合材料领域的科学和技术进展，以便更好地了解如何开发用于地坪应用的优质纳米复合材料。这项研究探讨了纳米填料（即碳纳米材料或层状粘土）与膨胀型阻燃剂结合的协同效应，以及不含膨胀型阻燃剂的纳米填料（即多壁碳纳米管/蒙脱石）对聚丙烯的热、机械、可燃性能和形态的协同效应。这些信息将有助于设计出具有更好的热性能、机械性能和可燃性能的聚丙烯地板材料。因此，研究证实，聚丙烯复合材料的形态（纳米填料在聚丙烯中的分散状态）、机械性能和可燃性之间存在着一定的关系。亮点碳纳米材料和粘土基 PP/CaCO3 复合材料的新进展制备、结构、性能和机理之间的关系无机阻燃剂的协同效应、多功能性和地板应用 PP/CaCO3 / 无机阻燃剂发展的挑战和未来展望
